Clearly aimed at a micro, small, or home office, or as a personal printer in any size office, the Samsung ML-2955ND ($130 street) is small enough to fit on a desk comfortably, yet offers an appropriate paper capacity and speed to serve as either a personal or shared printer. It doesn't hurt at all that the price is low enough to make it highly affordable as well.
The ML-2955ND has a lot in common with the slightly more expensive Brother HL-2270DW ($150 street, 4 stars), starting with a similar size. Both are smaller than many inkjets. The ML-2955ND measures 7.7 by 13.7 by 13.3 inches (HWD). That makes it taller than the Brother printer by a little less than an inch, but it also gives it a slightly smaller footprint.
Shared features include wired network support, along with a USB connection, and essentially identical paper handling. The network support makes the printers easy to share. The paper handing is appropriate for either a micro office or personal use, with a 250-sheet tray, 1-sheet manual feed, and built-in duplexer for printing on two sides of the page. Neither printer offers additional paper handling options.
One feature the HL-2270DW offers that the ML-2955ND doesn't is wireless network support. If you need WiFi, however, you can get the Samsung ML-2955DW ($150 street), which Samsung says is identical to the ND version except for the added WiFi.
Setup and Speed
For my tests, I set up the ML-2955ND on a network using a wired connection and installed the driver on a system running Windows Vista. Setup was standard fare. On our business applications suite, I timed the printer (using QualityLogic's hardware and software for timing) at an effective 8.5 pages per minute (ppm), a speed that's best described as acceptable but unimpressive.
The printer is certainly slower than I'd expect for the 29 ppm rating, which is roughly the speed you should see for printing text documents without graphics or photos. The HL-2270DW, for example, is rated at 27 ppm, but came in or our tests at 11.7 ppm. Under the category of being faster than expected, the HP LaserJet Pro P1102w ($149 direct, 3.5 stars), which is rated at only 18 ppm, managed 11.4 ppm on our tests.
Output Quality and Other Issues
Output quality is just a touch below par overall, with text that's a small step below par, absolutely par graphics, and photos at the low end of the very tight range where most mono lasers fall. The good news is that even with slightly below par text quality for a mono laser, the text is easily good enough for most business use. You shouldn't have any complaints about it unless you have an unusual need for small fonts.
As with most mono lasers, graphic output was easily good enough for any internal business need. Depending on how demanding you are, you may consider it good enough for PowerPoint handouts and the like. Photo output was more than good enough to print recognizable images from photos on Web pages. Depending on how demanding you are, once again, you may or may not consider them good enough for output like client newsletters.
One other issue that demands mention is the printer's running cost. The claimed 3 cents per page isn't particularly high for this price range, but it is 0.9 cents higher than Brother claims for the HL-2270DW. With only a $20 difference in initial price, if you buy the Brother printer, you can make up the difference by printing roughly 2,200 pages over the lifetime of the printer. Anything more than that, and the Brother printer will be cheaper in the long run.
Partly making up for this potentially higher total cost is the Samsung printer's Eco mode which, with default settings, switches the printer to duplex printing and toner saver mode with one touch of a button on the control panel. However, Samsung doesn't say how much the toner saver mode actually saves.
As may seem obvious, the Samsung ML-2955ND can be a good fit as a shared printer in a micro office or as a personal printer in any size office. If you're considering it, however, you should take a look at the Brother HL-2270DW as well. Depending on how many pages you expect to print, either choice could wind up being the better buy.

BEIJING (AP) ? Clouds of smoke from Lunar New Year fireworks sent air pollution readings soaring in the more sensitive measurement system Beijing started using a little more than a week ago, reports said Sunday.
Readings of fine particulate matter called PM2.5 reached 1.593 milligrams per cubic meter on the Jan. 22 eve of the holiday, about 100 times worse than the amount considered good for 24-hour exposure, the city's environmental bureau said.
The reading drew wide publicity in the local media on Sunday. The popular Beijing Youth Daily praised the city government for taking a more critical look at air pollution, while urging residents to consider the environmental effects of setting off fireworks.
The readings moderated under relatively clear skies in recent days. By noon Sunday, before the weeklong holiday ends and people return to work, the level stood at a relatively good 0.039.
Beijing is frequently cloaked in yellow haze that obscures buildings a couple of blocks away. On particularly bad days, schools cancel outdoor activities and hospitals treat more people ? particularly the elderly ? for respiratory complaints.
The city began measuring the small particles in the air and releasing the readings on Jan. 21, as concern has grown over Beijing's air pollution from all sources. PM2.5 ? particles less than 2.5 micrometers in size, or about 1/30th the width of an average human hair ? are believed to be the greatest health risk because their smallness means they can lodge deeply in the lungs.
Beijing previously had only given PM10 measurements of coarser particles, which indicated pollution was "light," leading to accusations the true extent of the problem was hidden.
The U.S. Embassy since last year has released PM2.5 readings from a device on its rooftop and some residents have tested the air in their neighborhoods and posted the results online.
The embassy measured more pollution than the city on Sunday, but the sampling stations are 10 miles apart or more.
Beijing says its PM2.5 measuring station is about 4 miles (7 kilometers) west of central Tiananmen Square.

A clinical study published Monday in the online edition of the Archives of Neurology is the first of its kind to link participation in reading, brain games and writing with a decreased production of a special protein whose presence has been linked to Alzheimer's disease.
Synopsis of Clinical Study
Three groups of study participants were observed and tested periodically over a five year period: Group One: 65 healthy individuals, mean age of 76.1 years; Group Two: 10 individuals diagnosed with Alzheimer's disease; and Group Three: The control group, 11 individuals with a mean age of 24.5 years, as noted in the Archives of Neurology.
Conclusions reached by the study panel were that people who were involved in the greatest levels of cognitive activities in the early and middle parts of their lifespans were the least likely to have the brain deposits of amyloid.
Although the physical activity of the participants were not observed during this study, researchers inferred that many people who choose a lifestyle involving cognitive activities also participate in a lifestyle that includes physical activity. Based on this inference, researchers extrapolated that both cognitive and physical activity throughout the lifespan contribute to fewer deposits of amyloid in the brain.
Acceptance of Amyloid Deposits in Brain Being Associated with Alzheimer's Disease
A study published June 2011 in the Annals of Neurology speaks to the association of amyloid deposits in the brain, along with subsequent atrophy, in Alzheimer's disease. Study authors noted that the deposits and some brain atrophy were present even before cognitive symptoms such as memory loss are evident.
The Alzheimer's Association published an entry commenting on the validity of this study, commenting that it was well conducted and controlled research using the most up-to-date techniques in brain imaging. The association concurred with the findings.
Known Prevention and Treatment of Amyloid Brain Deposits
MedlinePlus, a service of the U.S. National Institutes of Health, explains that the cause of amyloid brain deposits is unknown -- as well as the treatment of the deposits. Until future research can reveal more information in this area, the current findings that point to cognitive and physical activity as ways to stave off these protein deposits provide an avenue of hope.
What This Study Means to Baby Boomers
As ABCNews.com reports, Alzheimer's disease is the most common form of dementia after age 60. Although not conclusively proven, it is currently thought that amyloid deposits in the brain lead to the development of the dreaded disease.
While baby boomers and their seniors cannot turn back the clock to change lifestyle factors in their early lives, they can make lifestyle choices now -- to participate in cognitive activities such as reading, writing and playing various games and to participate in regular physical activity -- that may decrease their chances of developing Alzheimer's disease.
Smack dab in the middle of the baby boomer generation, L.L. Woodard is a proud resident of "The Red Man" state. With what he hopes is an everyman's view of life's concerns both in his state and throughout the nation, Woodard presents facts and opinions based on common-sense solutions.

Android powers on with added steam from the Kindle and Nook
The latest figures for the tablet market have been published by Strategy Analytics.
And the analyst firm has recorded more slippage in slate market share for Apple. The figures are for Q4 2011 market share, and show that the iPad has dropped to 58% from 68% in the final quarter of 2010.
That?s a considerable chunk of the market to lose to Android, which now holds 39%, up 10% year-on-year. The 40% mark is a figure that, earlier last year, some analysts were predicting Android would only reach in 2014.
Apparently the Kindle Fire and Nook budget Android slates represent some 40% of the Android slate share, so are currently driving the droid tablet world in the catch-up stakes, as anticipated.
Of course, these are estimates for tablets shipped, and how many are actually sold to consumers is another matter which is entirely more difficult to quantify.
Apple does tend to keep its inventory moving tightly with demand, and of course, the iPad 3 is just around the corner which could ? and very likely will ? change the market again.
Neil Mawston, Executive Director at Strategy Analytics, commented: ?Android captured a record 39 percent share of global tablet shipments in Q4 2011, rising from 29 percent a year earlier. Global Android tablet shipments tripled annually to 10.5 million units.?
?Android is so far proving relatively popular with tablet manufacturers despite nagging concerns about fragmentation of Android?s operating system, user-interface and app store ecosystem.?
Global tablet shipments were 67 million units for 2011, up 260% on the previous year. The analyst firm noted consumers were increasingly purchasing tablets rather than laptops or even entry-level desktops.

MELBOURNE, Australia ? If anyone knows how Novak Djokovic feels after sweating and scrapping for almost five hours in the Australian Open semifinals, it's his next opponent ? Rafael Nadal.
A day after Nadal beat Roger Federer in four compelling sets, Djokovic dug deep to overcome Andy Murray 6-3, 3-6, 6-7 (4), 6-1, 7-5 on Friday night after 4 hours, 50 minutes.
Defending champion Djokovic will face Nadal in a third straight Grand Slam final on Sunday. It's a reversal from three years ago, when Nadal had to regroup after his own lengthy semifinal.
The Spaniard needed 5 hours, 14 minutes in 2009 to get past compatriot Fernando Verdasco in the longest men's singles match in the tournament's history. He was so exhausted, he didn't lift a racket the following day.
Yet when the final rolled around, he beat Federer ? who had an extra day to rest ? in five sets that reduced the usually composed Swiss player to tears.
Now a weary Djokovic has less than 48 hours to prepare to face Nadal, one of the most fit players in the game.
"I know that I maybe have a mental edge because I've won six finals. ... We played in 2011 and I've had lots of success against him," Djokovic said. "That's going to be my main priority and concern the next day and a half, to physically be able to perform my best and be ready to play five sets."
Djokovic won 10 titles in 2011, six of them by beating Nadal in finals. Just as Nadal has the mental edge over Federer, Djokovic has developed a hold over the Spaniard.
But the No. 1-ranked Djokovic has shown chinks in his armor at Melbourne Park this year. Against David Ferrer in the quarterfinals, he struggled to breathe through most of a straight-sets win and at one point, clutched his leg in agony.
Against Murray, he looked completely spent again when he hobbled gingerly back to his chair after dropping serve to go down 2-1 in the third set.
"He's done it many times before," Murray said. "He runs very well even when he's breathing heavy. I was ready for that. He was similar in the last match. But he moved fine."
Murray had his own slump when he lost the fourth set in 25 minutes ? an aberration in a match featuring long baseline rallies that quite often ended in errors.
One rally in the eighth game of the second set ended after 41 shots. The third set lasted nearly an hour and a half, with the opening game taking almost 15 minutes alone. There was one serve-volley point in the entire match, won by Murray.
The gap between the top-ranked player and the No. 4 was mostly indiscernible throughout a match featuring 18 breaks of serve and almost as many changes in momentum.
When a scampering Murray knocked a forehand into the net on the final point, Djokovic collapsed onto the court. He shared a warm hug with his old friend Murray, sank to his knees and did the sign of the cross, then turned to his players' box and thumped his chest.
Many of his 70 match wins in 2011 seemed to come easy ? this was anything but.
"Definitely one of the best (wins) under the circumstances," Djokovic said. "Time wise, I think this was one of the longest, if not the longest, that I've played in the later stages of a Grand Slam.
"As a tennis player, you practice hard every single day knowing that you will get an opportunity to be part of such a great match and on such a high level."
After losing the last two finals at the Australian Open, Murray went out a round earlier this time but left more encouraged than ever that he can break through and become the first British man to win a Grand Slam singles title since 1936.
"Tonight's match was important for many reasons," the 24-year-old Murray said. "Obviously I wanted to win first and foremost. But also sort of after last year, the year that Novak's had, I think there's a very fine line between being No. 1 in the world and being 3 or 4. I think that gap, I feel tonight I closed it.
"My job over the next two or three months is to surpass him and the guys in front of me."
After Victoria Azarenka and Maria Sharapova go for the women's title and the No. 1 ranking on Saturday, Djokovic will bid for his fifth major title in Sunday men's final, with the chance to become only the fifth man in the Open Era to win three straight Grand Slam titles.
If he can achieve that, Djokovic would make 10-time Grand Slam winner Nadal the first man since the Open Era began in 1968 to lose three straight major finals. Just like Nadal three years ago, Djokovic doesn't plan on doing much before Sunday's final.
"I think I had enough time spent on the court. Now it's all about recovery," said Djokovic, who has won 19 consecutive Grand Slam matches.
After a year in which almost everything went his way and he overtook Nadal and Federer for the No. 1 ranking, Djokovic is just finding out what it feels like to be the hunted rather than the hunter.
"I'm aware now that everyone wants to win the major title, get that No. 1 spot, he said. "It's normal. It's something I'm prepared for."

The Dow Jones industrial average was trading near its highest close since the 2008 financial crisis Thursday afternoon after solid news on factory orders and strong earnings from U.S. manufacturers highlighted the economy's growing momentum.
Broader market indexes edged lower, though they are also sharply higher this year. Traders appear less afraid of spillover damage from the European debt crisis, and data on jobs and manufacturing have been consistently strong.
"With global risk off center stage and attention going back to the fundamentals, this market was ready to explode, which is exactly what it is doing," said Doug Cote, chief market strategist with ING Investment Management.
Before the market opened, the government reported that unemployment claims rose only modestly last week after a steep decline the week before. The long-term trend still indicates an improving job market.
Orders to factories for long-lasting manufactured goods increased in December for the second straight month, and a key measure of business investment rose solidly.
That strong demand was apparent in quarterly earnings reports from U.S. manufacturers. 3M stock rose 1.1 percent after its fourth-quarter profit beat Wall Street's estimates.
Caterpillar, the world's biggest heavy equipment maker, soared 3 percent, the most of the 30 companies in the Dow, after beating analysts' estimates last quarter. The company expects to do the same this year as global demand remains high.
The Dow Jones industrial average was up 14 points, or 0.1 percent, at 12,771 shortly after noon. 3M and Caterpillar led the gains.
The Dow is within reach of its post-financial crisis high of 12,810, reached in April 2011. The last time it closed higher than that was on May 20, 2008, when it settled at 12,826. The Dow's post-crisis high during the trading day was 12,928, reached in May 2011.
The Dow is up nearly 5 percent so far this year. The S&P 500 and Nasdaq have gained even more.
The Dow would need to rise another 11 percent to get to its record high close of 14,164, reached on Oct. 9, 2007.
The Standard & Poor's 500 index fell three points to 1,322. It was dragged lower by volatile financial companies and telecommunications firms. The Nasdaq composite index shed seven points to 2,811.
AT&T fell 2 percent, by far the most of the 30 companies in the Dow, after its earnings missed Wall Street's forecasts. The company remains heavily dependent on the Apple iPhone, which it pays to subsidize, but recently lost its exclusive rights to sell the phone in the U.S.
Stocks had their highest close in eight months Wednesday after the Federal Reserve said it plans to keep interest rates extremely low until late 2014 to encourage lending and investment and support the economic recovery.
The announcement lifted investments across many markets and continents. Bond prices rose in the U.S. and Europe. So did commodities, the euro, emerging market currencies and European stocks.
The yield on the 10-year Treasury note fell to 1.95 percent from 1.99 percent late Wednesday. The prospect of more bond-buying by the Fed helped make Treasurys more attractive. A bond's yield falls as demand for it increases.
A strong bond auction by Italy also brightened Europe's outlook, signaling to investors that lenders believe Italy will not be dragged into the debt crisis. And Greece resumed talks with its lenders over writing off some of its crushing debt.
Benchmark indexes in France, England, Germany and Italy closed up 1 to 2 percent.
Among the other U.S. companies making big moves after reporting quarterly earnings:
? Time Warner Cable Inc. rose 7 percent after the company reported earnings that were far above analysts' estimates. The national cable TV provider also raised its dividend 17 percent to 56 cents per share and announced plans to buy back more of its own stock.
? United Continental Holdings, the parent company of United and Continental airlines, surged 7.4 percent. The company's fourth-quarter loss narrowed, its adjusted earnings were more than double what analysts had expected and the cost of integrating the two companies fell.
? Netflix soared 21.5 percent, the most of any stock in the S&P 500, after the video streaming and DVD-by-mail company reported a huge gain in customers and a bigger fourth-quarter profit than analysts had expected.
? Colgate-Palmolive rose 1.3 percent after saying it will raise prices in the U.S. for the first time in years to cover higher costs for materials. The company's profit declined last quarter, but core sales in emerging markets were much stronger.

BENGHAZI, Libya (AP) ? Moammar Gadhafi loyalists have seized control of a Libyan mountain city in the most serious challenge to the central government since the strongman's fall, underlining the increasing weakness of Libya's Western-backed rulers as they try to unify the country under their authority.
The taking of Bani Walid, one of the last Gadhafi strongholds captured by the new leadership late last year, was the first such organized operation by armed remnants of Gadhafi's regime. A simultaneous outbreak of shootings in the capital and Libya's second largest city Benghazi raised authorities' concerned that other networks of loyalists were active elsewhere.
The security woes add to the difficulties of the ruling National Transitional Council, which is struggling to establish its authority and show Libyans progress in stability and good government. Bani Walid's fall comes after violent protests in Benghazi, where Libyans angry over lack of reform stormed the NTC headquarters and trashed offices.
In Bani Walid, hundreds of well-equipped and highly trained remnants of Gadhafi's forces battled for eight hours on Monday with the local pro-NTC revolutionary brigade, known as the May 28 Brigade, said Mubarak al-Fatmani, the head of Bani Walid local council. The brigade was driven out and Gadhafi loyalists then raised their old green flag over buildings in the western city.
Four revolutionary fighters were killed and 25 others were wounded in the fighting, al-Fatmani said.
There were no immediate signs that the uprising was part of some direct attempt to restore the family of Gadhafi, who was swept out of power in August and then killed in the nearby city of Sirte in October. His sons, daughter and wife have been killed, arrested or have fled to neighboring countries.
Instead, the fighting seemed to reflect a rejection of NTC control by a city that never deeply accepted its rule, highlighting the still unresolved tensions between those who benefited under Gadhafi's regime and those now in power. Those tensions are tightly wound up with tribal and regional rivalries around the country.
The May 28 Brigade had kept only a superficial control over the city, the head of Bani Walid's military council, Abdullah al-Khazmi, acknowledged.
"The only link between Bani Walid and the revolution was May 28, now it is gone and 99 percent of Bani Walid people are Gadhafi loyalists," he said.
He spoke to The Associated Press at a position on the eastern outskirts of Bani Walid, where hundreds of pro-NTC reinforcements from Benghazi were deployed with convoys of cars mounted with machine guns, though there was no immediate move to retake the city.
The fighters who captured the city Monday night belong to Brigade 93, a militia newly created by Gadhafi loyalists who reassembled after the fall of the regime, said al-Khazmi and al-Fatmani. The fighters, flush with cash and heavy weaponry including incendiary bombs, have been increasing in power in the city, they said.
There was no possibility to confirm their claims. However, there were no mass evacuations from the town after the clashes, an indication that the residents appear to accept the new arrangement, said Ali al-Fatmani, a revolutionary brigade commander in Bani Walid.
Authorities in Benghazi, where the NTC is centered, appeared concerned that the Bani Walid uprising could have sent a signal to other cells of Gadhafi forces.
An AP reporter who was present in the Benghazi operation room heard military commanders on Monday saying coordinated incidents of drive-by shootings in Tripoli and, to a lesser extent, Benghazi erupted as news of the Bani Walid takeover spread. In Tripoli, some shops closed, and fighters responsible for security in the capital were on a state of alert over the shootings.
Five months since the Gadhafi regime's fall and three months since his death, the National Transitional Council has so far made little progress in unifying its armed forces. Instead it relies largely on multiple "revolutionary brigades," militias made up of citizens-turned-fighters, usually all from a specific city or even neighborhood.
The militias were created during the months of civil war against Gadhafi's forces last year, and since the war ended in October, the various brigades remain in control of security affairs of each city they liberated. Though loyal to the NTC, they have also feuded among themselves and acted on their own initiative, and the council has been unable to control them.
A month ago, Gadhafi loyalists attacked another revolutionary brigade from Tripoli that entered Bani Walid, killing 13, said Mubarak al-Fatmani.
"The council (NTC) did absolutely nothing," said al-Fatmani, who resigned from his local council chief post to protest the NTC's failure to investigate the ambush. He still holds his position, since his resignation has not yet been accepted.
The council has faced increasing complaints that it is doing little to bring stability to the country. It faces a daunting task, since Gadhafi's regime stripped Libya of most institutions, and the civil war has stirred up widespread divisions, rivalries and resentments.
In the Benghazi unrest last Saturday, protesters broke into the NTC headquarters, smashed windows and carted off furniture and electronics, then threw bottles at NTC chief Mustafa Abdul-Jalil as he tried to address them and torched his car. The next day, Abdul-Jalil suspended the Benghazi representatives on the council in an apparent attempt to appease protesters. The deputy chief of the NTC resigned in protest over the suspension.
Bani Walid, a city of 100,000 located in the mountains 90 miles (140 kilometers) southeast of Tripoli, held out for weeks against revolutionary forces after Gadhafi's fall from power, with loyalist fighters dug into its formidable terrain of valleys and crevasses. Pro-NTC fighters finally took it in October.
The main tribe in Bani Walid is a branch of the Warfala tribal confederation, which stretches around the country with around 1 million members. The Bani Walid branch was one of the most privileged under Gadhafi, who gave them top positions and used their fighters to try to crush protests in the early months of last year's uprising against his rule.
That has left a deep enmity between the tribe and others. Ali al-Fatmani said Bani Walid loyalists were among Gadhafi troops that tried to march on Benghazi during the civil war and were used to in the siege of Zawiya, west of Tripoli. There were reports, he said, that Bani Walid fighters desecrated graves of fallen revolutionary fighters in Zawiya.
"The hatred and mistrust have been building up during the revolution," said al-Fatmani, himself a Warfala.

ScienceDaily (Jan. 23, 2012) ? An international team of researchers has discovered 13 new regions of the genome associated with the timing of menopause. These genes shed light on the biological pathways involved in reproductive lifespan and will provide insights into conditions connected to menopause, such as breast cancer and heart disease.
Menopause is a major hormonal change that affects most women when they are in their early 50s. The timing of menopause can have a huge impact on fertility, as well as influencing the risk of a range of common diseases such as breast cancer. It has been known for some time that genetic factors influenced the onset of menopause, however until recently very few genes had been identified.
In the new study, published in the journal Nature Genetics on 22 January 2012, Dr Anna Murray, University of Exeter, Peninsula College of Medicine and Dentistry (PCMD) Dr John Perry, PCMD and WTCHG, University of Oxford, and dozens of international collaborators, examined the genomes of over 50,000 women. They identified 13 novel gene regions associated with menopause onset, and confirmed four previously identified. Most of the 17 regions include genes related to DNA damage/repair or the immune system, whilst others are linked to hormonal regulation.
Dr Perry said: "The new findings highlight biological pathways not previously associated with reproductive lifespan, and may provide insights into the other conditions connected with menopause age, such as cardiovascular disease and breast cancer."
The association with breast cancer is related to the length of time a woman menstruates in total and is thought to be related to oestrogen exposure over a lifetime -- in fact earlier menopause is protective for breast cancer. Cardiovascular risk is increased in post-menopausal women compared to pre-menopausal and reduced oestrogen is thought to be a key component of this increased risk. Genetic studies will be beneficial in working out exactly what the relationships are between these conditions.
Dr. Murray added: "Menopause is a process most women go through, yet we know very little about what governs the timing of this key event in a woman's life. By finding out which genes control the timing of menopause we hope to be able understand why this happens very early to some women, reducing their chances of having children naturally."
The authors said they expected further research will identify additional genes, and also assess the impact of these genetic regions on related reproductive disorders. The research team are currently investigating women who had very early menopause, before 45 years, to determine whether the new menopause genes play a role in this clinically important condition which affects over five per cent of women.
Besides Dr Murray and Dr Perry, senior authors on the study include Professor Kathryn Lunetta and Dr Joanne Murabito at the Boston University schools of Public Health and Medicine, and Jenny A. Visser, a scientist at Erasmus Medical Center in Rotterdam (Netherlands).

CHICAGO ? Sen. Mark Kirk of Illinois could lose full use of his left arm and experience facial paralysis after a weekend stroke that required emergency surgery, but his physician said Monday the prospects for a complete mental recovery are strong.
Dr. Richard Fessler said it likely would be "very difficult" for the first-term Republican senator to regain movement in his left arm, and that his left leg and face also may be affected. Kirk was in intensive care at Northwestern Memorial Hospital, where he appeared to recognize those around him and was responding to verbal commands, Fessler said.
Though Fessler could not say when Kirk would be able to return to work, he described the senator as "young, very healthy and in good shape."
"Sen. Kirk's job is cerebral, and I believe the functions required to do his job are going to be fine," said Fessler, a neurosurgeon who removed a 4-by-8-inch piece of Kirk's skull Sunday night to relieve swelling on his brain.
Kirk, 52, had reported feeling dizzy and checked himself into Lake Forest Hospital over the weekend before being transferred to Northwestern. Tests showed he had a tear in the carotid artery on the right side of his neck. Carotid arteries carry blood to the brain and carotid tears are a common cause of strokes in people in their 50s or younger.
Fessler said Kirk would undergo rehabilitation, but added that the "the prospects for his full physical recovery, particularly on the left side of his body, are not great."
Dr. Joseph Broderick, a University of Cincinnati stroke expert, said that when removing part of the skull is required, "that is a pretty significant stroke" that likely has caused substantial damage.
The damage typically occurs when clots formed from a carotid artery tear lodge in the brain, depriving brain cells of oxygen. Brain cells then die and may fill with fluid, causing swelling. The process can take days or even weeks, he said.
"Those people almost always will have some type of deficit long-term. Some may get back to being functional, but some are left with very severe deficits," Broderick said.
Kirk's family said in a statement that he had "always shown great courage and resilience and we are confident that the fighter in him will prevail."
"We are very grateful for the excellent treatment and care provided by the doctors and their medical teams ... We are equally grateful for the love and support of our family and friends," the family said.
Illinois Sen. Dick Durbin, a Democrat, said Monday he was shocked to learn of Kirk's stroke because Kirk appeared to be a picture of health. A Kirk aide said the senator is a regular swimmer and has to pass medical checks every six months in the reserves.
West Virginia Sen. Joe Manchin, with whom Kirk planned to sit during Tuesday night's State of the Union Address, issued a statement calling Kirk a "dear friend and truly a great American."
He said he's confident Kirk "will make a speedy recovery and I will do everything I can to support him and his family until he is able to join us back here in Washington."
People can return successfully to high-profile jobs after serious brain injuries. Sen. Tim Johnson, D-S.D., suffered a brain hemorrhage in December 2006 and returned to the Senate the following fall. His speech was a bit slurred, and sometimes he used a scooter to get around. He later won re-election and chairs the Banking Committee.
Tradition holds that Kirk will continue to hold his seat in the Senate while recovering from the stroke. Democrats currently have a 51-47 advantage in the chamber, including the two independents who caucus with the party.
Kirk, a Naval reserve commander, won Barack Obama's vacated Senate seat for the Republican Party in 2010 after a hard-fought election during which the moderate from Chicago's northern suburbs had to make the transition to a statewide candidate who had to appeal to more conservative voters.
Kirk won the seat by campaigning as the level-headed voice of experience facing a young Democrat, citing his five previous terms in Congress.
Upon reaching the Senate, Kirk landed a seat on the powerful Appropriations Committee and late last year joined forces with Democratic Sen. Bob Menendez of New Jersey in imposing crippling sanctions on Iran.
The two senators sponsored an amendment to the annual defense bill that targets foreign financial institutions that do business with the Central Bank in Tehran. In a rare unanimous vote, the Senate backed the measure 100-0. Obama signed the wide-ranging defense bill with the sanctions on New Year's eve.

TAMPA, Fla. ? Ron Paul says he has no intention of running for president as a third-party candidate, though he's continuing to keep the door open a crack.
The Texas congressman is stopping short of saying no -- because he says he's not an absolutist. Paul notes that he once left Congress vowing not to return, only to run again.
But Paul says he doesn't have any plans to run outside the GOP and that he might even be able to endorse rival Newt Gingrich if he's the nominee. Paul says he is happy that Gingrich keeps hinting at attacking the Federal Reserve and jokes that if he could get Gingrich to listen to him on foreign policy, as Paul puts it, "we might just be able to talk business."

Katy Perry is cutting Russell Brand out of her life in more ways than one.
Late-night comedian Stephen Colbert brought his "exploratory committee," and satirical love for Super PACs, to South Carol...
The 27-year-old "Firework" singer has unfollowed her soon-to-be ex-husband on Twitter. As of Friday, Perry is still one of the 78 people Brand subscribes to via the social networking site.PHOTOS: Katy's crazy cleavage
It's not surprising, given that Perry is only communicating with Brand, 36, via phone or email. "She's limiting those interactions," a source tells the new issue of Us Weekly (out now). "He's being so atrocious that she feels like she never really knew him."
VIDEO: Why did Katy and Russell call it quits?
Perry has been keeping Brand off her mind by focusing on her career: she performed in Jakarta, Indonesia, on Thursday, and she recently shot an Adidas ad in Santa Barbara, Calif.
"She doesn't want to look battered and have people for sorry for her," a Perry source tells Us. "She's very strong and confident."PHOTOS: Katy and Russell's zany romance

YANGON, Myanmar ? Myanmar's president has told a U.S. newspaper that his country's democratic reforms are irreversible, as he urged the West to lift sanctions. He even dangled the possibility of giving opposition leader Aung San Suu Kyi a Cabinet post.
"We are on the right track to democracy," President Thein Sein said in the interview with The Washington Post published Friday, his first with Western media. "Because we are on the right track, we can only move forward, and we don't have any intention to draw back."
Suu Kyi's National League for Democracy responded to the newspaper report by saying it would be too early for the U.S. and its allies to lift economic sanctions because the reforms aren't complete yet. It also welcomed the notion of a Cabinet post for Suu Kyi, while saying it was too early to discuss the matter.
Thein Sein's government took office in March, ending a half century of military rule. Since then, it has rolled out reforms at a pace that has surprised even Myanmar's staunchest critics.
Thein Sein said he felt his government had met the West's conditions for lifting sanctions by releasing many political prisoners, scheduling parliamentary elections for April 1 and allowing Suu Kyi among others to participate.
"What is needed from the Western countries is for them to do their part," he said.
Thein Sein repeatedly called for the lifting of severe economic sanctions that the U.S., European Union and others imposed while Myanmar was under military rule. He said the sanctions hurt the people of Myanmar much more than the former junta leaders and were holding back the country's economic progress.
The U.S. and European Union have praised the recent reforms but said they will monitor how the April vote is conducted, among other considerations, before revising sanctions.
Suu Kyi has said she will personally contest the elections, a historic event that could usher the Nobel laureate and former political prisoner into her first parliamentary seat.
"If the people vote for her, she will be elected and become a member of Parliament. I am sure that the Parliament will warmly welcome her. This is our plan," Thein Sein said.
Asked if he would like to see Suu Kyi in his government, Thein Sein replied: "If one has been appointed or agreed on by the Parliament, we will have to accept that she becomes a Cabinet minister."
Nyan Win, the spokesman for Suu Kyi's National League for Democracy, said it was premature to speak of a Cabinet post but that Suu Kyi "is a very capable leader and she could take any leading position." He also said it was too early to lift sanctions.
"We acknowledge that reforms have been made in the country and we welcome the reforms. However, we don't consider the reforms complete yet," Nyan Win said.
After a recent visit to Myanmar, U.S. Sen. Mitch McConnell said he would take his cue on lifting sanctions from Suu Kyi. He said a key test would be free and fair conduct of April 1 elections. He also sought more moves to end ethnic violence, and for Myanmar to discontinue its relationship with North Korea, which is suspected to have sold it missiles in defiance of U.N. Security Council resolutions. Some in the U.S. Congress maintain that there is ongoing nuclear cooperation between the two countries.
Thein Sein said the two countries have diplomatic relations but denied any military ties with North Korea.
"These are only allegations," he said. "We don't have any nuclear or weapons cooperation with (North Korea)."
Thein Sein said that the government was committed to ending the country's long-running ethnic conflicts and was currently communicating with all armed ethnic groups. Cease-fire pacts have been signed with some, including the Karen.
"Soon we will try to achieve an eternal peace in country. However, this will require time," he said.

ScienceDaily (Jan. 20, 2012) ? By tweaking the smallest of parts, a trio of University at Buffalo engineers is hoping to dramatically increase the amount of sunlight that solar cells convert into electricity.
With military colleagues, the UB researchers have shown that embedding charged quantum dots into photovoltaic cells can improve electrical output by enabling the cells to harvest infrared light, and by increasing the lifetime of photoelectrons.
The research appeared online last May in the journal Nano Letters. The research team included Vladimir Mitin, Andrei Sergeev and Nizami Vagidov, faculty members in UB's electrical engineering department; Kitt Reinhardt of the Air Force Office of Scientific Research; and John Little and advanced nanofabrication expert Kimberly Sablon of the U.S. Army Research Laboratory.
Mitin, Sergeev and Vagidov have founded a company, OPtoElectronic Nanodevices LLC. (OPEN LLC.), to bring the innovation to the market.
The idea of embedding quantum dots into solar panels is not new: According to Mitin, scientists had proposed about a decade ago that this technique could improve efficiency by allowing panels to harvest invisible, infrared light in addition to visible light. However, intensive efforts in this direction have previously met with limited success.
The UB researchers and their colleagues have not only successfully used embedded quantum dots to harvest infrared light; they have taken the technology a step further, employing selective doping so that quantum dots within the solar cell have a significant built-in charge.
This built-in charge is beneficial because it repels electrons, forcing them to travel around the quantum dots. Otherwise, the quantum dots create a channel of recombination for electrons, in essence "capturing" moving electrons and preventing them from contributing to electric current.
The technology has the potential to increase the efficiency of solar cells up to 45 percent, said Mitin, a SUNY Distinguished Professor. Through UB's Office of Science, Technology Transfer and Economic Outreach (STOR), he and his colleagues have filed provisional patent applications to protect their technology.
"Clean technology will really benefit the region, the state, the country," Mitin said. "With high-efficiency solar cells, consumers can save money and providers can have a smaller solar field that produces more energy."
Mitin and his colleagues have already invested significant amounts of time in developing the quantum dots with a built-in-charge, dubbed "Q-BICs." To further enhance the technology and bring it to the market, OPEN LLC is now seeking funding from private investors and federal programs.

TUESDAY, Jan. 17 (HealthDay News) -- The experimental cancer drug regorafenib appears to extend survival slightly in patients with metastatic colorectal cancer, a new trial indicates.
Regorafenib is a so-called multikinase inhibitor, which targets several of the ways cancer develops and grows, researchers said.
"The drug was tested on patients with metastatic colorectal cancer who had progressed after standard therapies, meaning they had no treatment options available," lead researcher Dr. Axel Grothey, a professor of oncology at the Mayo Clinic, said during a noon press conference at the Gastrointestinal Cancers Symposium in San Francisco on Tuesday.
The drug is designed to stop tumor progression, both by preventing cancer cells from growing and by preventing these cells from developing the blood vessels needed to keep them alive, the researchers explained.
In the trial, more than 700 patients with metastatic colon cancer were randomly selected to receive regorafenib or placebo.
In addition, all patients received care to treat symptoms, but not to change the course of the disease, the researchers noted.
Treatment included antibiotics to fight infections, painkillers and corticosteroids.
The investigators found that patients taking regorafenib survived an average of 6.4 months, compared with five months for those receiving a placebo -- an increase in survival of 29 percent.
In addition, 44 percent of the patients taking regorafenib responded to the drug or had their cancer slowed, compared with 15 percent of the patients receiving placebo, they reported.
Based on these findings, the trial was stopped in October so that all patients could be offered the drug.
The trial was funded by the maker of regorafenib, Bayer HealthCare Pharmaceuticals.
"The drug helped patients live longer," said Dr. Len Lichtenfeld, deputy chief medical officer for the American Cancer Society. "But you have to keep in mind that these patients had advanced disease."
And, the gains were modest, he added. "Patients who got the drug lived about one month longer. Unfortunately, the difference between the groups in the time it took for the disease to get worse was small -- about six days," he said.
Lichtenfeld thinks that using the drug earlier in treatment might have more impact. "But not every drug, when moved earlier in the course of the disease, is necessarily proven to be effective," he cautioned.
Grothey noted regorafenib is being tested in a phase 2 trial in patients with earlier stage colorectal cancer, in hopes that the results will be even more dramatic.
Research presented at medical meetings should be viewed as preliminary until published in a peer-reviewed medical journal.

MYRTLE BEACH, S.C. ? The Republican presidential contenders on Monday campaigned their way into the first of two debates before a pivotal weekend primary in South Carolina, with Mitt Romney savoring an endorsement from the latest campaign dropout and his pursuers struggling to emerge as the race's principal conservative.
Hours before the debate, former Utah Gov. Jon Huntsman withdrew from the race and announced his support for Romney despite their differences. He appealed to all remaining contenders to stop attacking one another.
There appeared little likelihood of that happening, either in the TV commercials, mail and other advertising blanketing the state ahead of Saturday's vote or, possibly, on the debate stage itself.
Romney wasn't present for Huntsman's endorsement, and Newt Gingrich, Rick Santorum, Rick Perry and Ron Paul all but ignored it as they sought to slow the front-runner's momentum in the race to pick a Republican rival to President Barack Obama this fall.
Romney has victories in the only two contests of the campaign thus far, the Iowa caucuses and New Hampshire primary earlier this month. Gingrich has conceded that the former Massachusetts governor will likely be the party's nominee if he is similarly victorious in South Carolina, an assertion that none of the others in the race has so far contested.
That raised the significance of the night's debate, as well as another one scheduled for Thursday in Charleston.
Romney is the leader in the public opinion polls in South Carolina, although his rivals hope the state's high, 9.9 percent unemployment rate and the presence of large numbers of socially conservative evangelical voters will allow one of them to slip by him.
Huntsman was the second campaign dropout to endorse Romney, after former Minnesota Gov. Tom Pawlenty. Minnesota Rep. Michele Bachmann, who quit after a last-place finish in Iowa, has not yet said which of the remaining contenders she supports. Herman Cain, who left the race in December after facing allegations of sexual impropriety, has promised an endorsement soon.
Huntsman's parting announcement included a reference to the differences he and Romney had. But he left the podium without responding to questions about his remark last week, in the run-up to the New Hampshire primary, that Romney was unelectable and out of touch.
It was unclear why Romney did not attend the announcement. He was in town for a later campaign appearance and then the debate.
Gingrich and Perry both began their day at a Martin Luther King Jr. Day observance, where they praised the legacy of the slain civil right legacy.
At about the same time, Santorum was complaining that attacks launched against him by a political action committee supporting Romney was spreading lies. He called on Romney to ask the group to edit or remove its ads from the air.
The attack on Santorum is patterned after one that helped send Gingrich into a nosedive in the polls in the final weeks of the Iowa caucus campaign.
Gingrich made similar demands on Romney to rein in his supporters, but was ignored.
Paul, who generally keeps a light campaign schedule, had a mid-afternoon speech to the state tea party convention.
