Cobook, A Slick Address Book App That Doesn?t Upload Your Data

cobook-01The mundane Address Book was big news this week due to the privacy fiasco, but here's a post about an impressive address book app with a different approach to privacy. Cobook is a Mac contact management app that's simple, powerful and actually fun to use. The software, made by a boot-strapped startup, is now in a free beta test, with 60,000 downloads since it launched at the end of January. Cobook is what the Mac OSX Address Book should be. It sits in the menu bar or can be undocked and instantly synchronizes with Apple's Address Book. Any data entered into Cobook gets synced to your other computers and devices. Because it?s a native app, adding contacts, assigning tags, and editing contact info is very quick. Your Facebook, Twitter, and LinkedIn contact info can also be pulled in, and if you hover over it, a pop-up window displays your contacts' Facebook info, Tweets, or LinkedIn profile.

Universal robot gripper sinks shots, throws darts, makes us feel inadequate (video)

Universal Gripper
Soon there will be little left for us puny humans. Robots have long since replaced us at most menial tasks, now they're looking to claim our lucrative professional sports contracts. They've already proven their mettle at baseball, basketball and hockey. Now researchers at the University of Chicago and Cornell are getting their coffee-filled balloon bot in on the action -- albeit with slightly less ambitious prey in its sights. Dorm room stoners proficient in NERF basketball, drunken dart fanatics and school yard marble hustlers may all be answering to this mechanical party favor soon enough. Don't believe us? Check out the video after the break. Just hope this guy is on your team in the next round of beer pong.

Smoking cessation meds shows promise as alcoholism treatment, study suggests

ScienceDaily (Feb. 15, 2012) ? A medication commonly used to help people stop smoking may have an unanticipated positive side effect for an entirely different vice: drinking alcohol. A new study by University of Chicago researchers finds that varenicline, sold as Chantix, increases the negative effects of alcohol and therefore could hold promise as a treatment for alcoholism.

A group of heavy-to-moderate social drinkers given a single dose varenicline three hours before an alcoholic beverage reported increased dysphoria and reduced "liking," even when researchers controlled for the effects of nausea from the drug. Those effects upon the subjective response to alcohol could reduce drinking in people prone to bingeing and other forms of abuse.

"We found that varenicline increased the unpleasant effects of alcohol and decreased drug liking," said Emma Childs, PhD, research associate at the University of Chicago Medicine and first author of the study published in Alcoholism: Clinical and Experimental Research. "Thus, we think that varenicline may reduce drinking by altering the effects of alcohol."

Some patients prescribed Chantix to quit smoking have anecdotally reported a reduction in consumption of alcohol as well, and controlled studies in animals and humans have supported the effect. Researchers are now looking for neurobiological mechanisms that connect varenicline, a partial agonist of the brain's nicotinic receptors, with reduced alcohol craving or consumption.

"Smokers who use varenicline are approximately two to three times more likely to remain abstinent six months or more after their quit date," said Childs. "After it was approved, several patients treated with varenicline also reported reductions in their drinking, so investigators began to assess if this was an actual effect and how it might be produced."

The new experiment is the first to look at the acute effects of a single dose of varenicline on the subjective response to a subsequent alcoholic drink. Subjects were recruited based on heavy drinking behavior, not smoking behavior -- though the recruits did smoke 4 cigarettes a day on average.

15 subjects (8 men and 7 women) were brought to the laboratory for six different sessions. On each day, the subject received either a varenicline or placebo capsule, and then three hours later was given a drink containing 0, 0.4, or 0.8 mg/kg alcohol. Researchers monitored the effects of the drink on cardiovascular and eye movement measures, and subjects filled out questionnaires to report the subjective effects of the drink.

Compared to sessions where the subjects received a placebo pill, varenicline increased nausea, heart rate, blood pressure. After an alcoholic drink, self-reported dysphoria was increased while alcohol effects on subconscious eye movements (a measure of the drugs' objective effects) were reduced. Even after controlling for the effect of nausea upon the subsequent response to a drink, the increased dysphoria and reduced "drug liking" after drinking alcohol remained significant.

By increasing the negative effects of alcohol, varenicline might be most effective in people who are unable to stop consuming alcohol after only one drink, Childs said.

"Our findings shed light on the mechanism underlying why people consume less alcohol when they have taken varenicline," said Childs. "The pleasurable effects of alcohol, for example feeling 'buzzed' and talkative, are associated with greater consumption and binge drinking. Some people lose control of their alcohol consumption during a drinking episode, for example they may aim to only have one or two drinks but end up drinking say four or five. If varenicline counteracts these positive effects by producing unpleasant effects, then as a result people may consume less alcohol during a drinking episode."

The authors cautioned that their study only examined the acute effect of a single dose of varenicline, rather than the sustained exposure experienced with regular use of the drug. But because the effectiveness of varenicline has already been proven as a smoking cessation drug, the unanticipated effects on drinking may make people struggling with both behaviors a logical first target.

"Varenicline may find a nice niche in those individuals who are both nicotine and alcohol dependent, who we know represent a large portion of alcohol-dependent individuals," added Hugh Myrick, associate professor of psychiatry at the Medical University of South Carolina, who was not involved in the study. "Since there is a high comorbidity between nicotine and alcohol dependence, a single medication that could decrease the use of both substances would be ideal."

Analysis: New China landing vessels point to Pacific rivalry (Reuters)

HONG KONG (Reuters) ? As looming budget cuts force the Pentagon to plan for a smaller U.S. navy, China is accelerating the launch of new, increasingly capable warships as part of a sustained drive to become a major maritime power.

Shanghai's Hudong Zhonghua Shipbuilding Company late last month launched the fourth of China's new 071 amphibious landing ships according to reports carried by Chinese military web sites and the state-controlled media.

While most attention has been drawn to the ongoing sea trials of China's first aircraft carrier, military analysts say the expanding fleet of 20,000 tonne landing ships, the biggest domestically designed and built vessels in the Chinese navy, delivers a far more immediate boost to Beijing's global influence.

"Having a significant fleet of large amphibious assault vessels clearly suggests a desire for power projection," says Christian Le Miere, a maritime security researcher at the International Institute for Strategic Studies in London.

"If you want the surgical insertion of forces, for a range of reasons, then you need amphibious response ships."

MILITARY RIVALRY

China's naval buildup comes amid mounting maritime tensions in the Asia-Pacific region, which is likely to be one of the main geopolitical stress points in the coming decade.

Military planners previously had focused mainly on a potential conflict in the Taiwan strait. More recently, however, Japan and China have locked horns over islands each claims in the East China Sea; Vietnam, the Philippines and other nations are disputing territorial claims with China over parts of the South China Sea thought to be rich in oil and gas.

The U.S. Navy has announced it will deploy its own new amphibious assault vessels, the Littoral Combat Ships, to the "maritime crossroads" of the Asia-Pacific theater, stationing them in Singapore and perhaps the Philippines.

Xi Jinping, the man destined to become China's new president later this year, called for enhanced military cooperation between the Pacific powers during a meeting with U.S. Defense Secretary Leon Panetta on Monday in Washington.

Xi, the son of a famous guerrilla commander from the 1930s, also met with President Barack Obama and was treated to a rare show of honors at the Pentagon, including on a 19-gun salute.

But Panetta, alluding to the strains in the relationship, called for more transparency from Beijing about its military build-up.

LARGEST SHIPBUILDER

The Chinese navy is expected to deploy up to eight of the type 071 ships that can carry up to 800 troops, hovercraft, armored vehicles and medium lift helicopters. The first of the class launched in 2006, the Kunlunshan, has already deployed with Chinese naval forces to the Indian Ocean and the pace of construction appears to have quickened with the third and fourth vessels completed within the last five months.

And, military commentators and retired Chinese naval officers say, early design work has already started on a bigger, more capable landing ship.

For the Chinese navy, the country's thriving commercial shipbuilding industry is providing a springboard for further improvements in the size and sophistication of new classes of warships, military experts say.

China in 2010 overtook South Korea to become the world's biggest shipbuilder and industry experts say the leading state-owned shipyards are steadily improving skills and technology with the launch of bigger and more complex oil tankers, container ships and other, more specialized vessels.

Along with more than two decades of rapid growth in military spending, this shipbuilding expertise has transformed the Chinese navy from an obsolete, coastal defense force to a blue water fleet that is expanding its influence into the Pacific and Indian Oceans.

China's best warships and submarines are now armed with advanced air defense weapons and long range, anti-ship missiles.

In its annual report to Congress on the Chinese military, the Pentagon last year said the People's Liberation Army (PLA) navy now has about 75 major warships, more than 60 submarines, 55 medium and heavy amphibious ships and about 85 smaller, missile-armed fast attack craft.

As a major trading power with a growing dependence on imported energy and raw materials, this naval expansion is crucial for the country's security, according to Chinese military planners.

"The safety of China's personnel, assets and shipping lanes is very important for its economy," wrote Senior Captain Wang Xiaoxuan, the director of the PLA's Naval Research Institute, in the official China Daily newspaper last month. "To guarantee this, it needs a strong navy."

SHRINKING US NAVY

Military strategists dismiss crude comparisons between navies based on the number of ships alone and most experts agree that the U.S. navy with its 285-strong fleet including 11 aircraft carriers, more than 70 nuclear powered submarines and 22 cruisers remains the world's overwhelmingly, dominant navy.

In size, firepower, integration with other important weapons systems and battle experience, the best U.S. warships enjoy a clear advantage over those of China and most combatants from other navies.

However, it is also clear that under the Obama administration's plan to shave almost $487 billion from the Pentagon budget over the coming decade, the U.S. navy will shrink as China's fleet continues to grow in size and quality.

To meet its budget target, the U.S. navy proposes to retire seven cruisers and two amphibious vessels, delay work on new ships and submarines and scrap some programs which could see the fleet shrink to less than 250 ships, according to senior Pentagon officials.

These cuts come as the Obama administration mounts a "pivot" to Asia following the U.S. withdrawal from Iraq and anticipated exit from Afghanistan.

As part of this effort to boost defense cooperation in Asia, the U.S. military is now holding its annual Cobra Gold joint exercises which run until February 17 in Thailand with troops from the host country, Indonesia, Malaysia, Singapore, South Korea and Japan. It will hold joint naval exercises next month with the Philippines near the disputed Spratly islands.

SECOND-RANKED SPENDER

This shift of military firepower to Asia and renewed emphasis on building closer ties with traditional, regional allies is partly aimed at countering the rapid growth of Chinese military muscle.

After more than two decades of double digit growth, the annual expansion of China's official military outlays dropped to 7.5 per cent in 2010 in the aftermath of the global financial crisis but spending bounced back last year with a 12.7 per cent increase to $91.5 billion.

Most foreign analysts believe China understates its defense budget.

The Pentagon estimates total Chinese military outlays in 2010 were more than $160 billion which would easily make it the second ranked defense spender behind the US.

The Obama administration is proposing to spend $525 billion on the military in 2013.

For the expanding Chinese navy, the widely publicized deployment of the refurbished, former Ukrainian aircraft carrier, the Varyag, on its sea trials last year was seen as an important milestone in China's bid to become a major sea power.

However, most Chinese and foreign experts believe it will be years before the carrier will be operationally ready with aircraft, weapons and supporting vessels.

PROTECTING OVERSEAS NATIONALS

In contrast, military analysts say the amphibious landing ships already provide Beijing the option of deploying troops and their equipment in wartime or in response to less serious peacetime contingencies, including operations to protect the more than 800,000 Chinese nationals working overseas.

"In non-combat roles, they are more meaningful than an aircraft carrier," says Gabe Collins, an Ann Arbor, Michigan-based specialist on maritime affairs for the China SignPost research group.

"They are geared to using choppers, troops, hovercraft and even armored vehicles. Now they can say: 'We've just had three people kidnapped here, let's go and do something about it'."

More ominously for smaller regional powers, these ships could also be used to land Chinese troops on disputed territory in the South China Sea, analysts say.

However, it is in so-called "soft power" that the amphibious landing vessels could make their initial contribution as China attempts to reassure regional nations that its growing military might poses no threat.

The Chinese military clearly recognized that the U.S. was able to gain substantial goodwill from its effective response to the 2004 Indian Ocean Tsunami with its aircraft carriers and amphibious assault ships ferrying supplies, medical teams and rescue crews ashore, according to Chinese and Western commentators.

Some analysts believe this experience was a factor in Beijing's decision to launch its first, large, military hospital ship that could be deployed to assist other nations in times of crisis as well as support Chinese amphibious forces in combat.

The hospital ship, launched in 2007, was late last year deployed on a humanitarian medical mission to Latin America and the Caribbean.

Retired NFL players still seeking better benefits

(AP) ? The group of retired NFL players that was part of the labor talks during the lockout last year has not given up a push for better post-career care.

The dozens of players, including several members of the Pro Football Hall of Fame, filed a lawsuit against the NFL Players Association last fall. The complaint alleges the union illegally sacrificed some of the league revenue that was supposed to go toward additional retirement benefits so that current players could keep more money.

U.S. District Judge Susan Richard Nelson will hear oral arguments from both sides in court on Wednesday in Minnesota.

NFLPA spokesman Carl Francis says the union won't comment on the lawsuit. The NFLPA has filed a motion to have the case dismissed.
