Shuttle Astronauts Add The ISS’s Last Major Piece

From Discover Magazine:

The International Space Station is almost done. Astronauts on board the current space shuttle Endeavour completed the first of three spacewalks to install the last major component of the ISS: the Tranquility module. Its huge windows will offer ISS residents 360-degree view of space, the station, and our home world.

The U.S. Tranquility module — shaped like a soda can — is the last major American addition to the station, now 98% complete. Its placement completes 11 years of U.S. construction work on the outpost, which the United States has spent more than $50 billion building [USA Today]. An Italian team designed the module’s magnificent dome, which measures 10 feet in diameter. Seven windows provide the panoramic view.

Analysis: Chocolate May Reduce Stroke Risk

From USA Today:

Just in time for Valentine's Day, research out this week suggests eating chocolate may have a positive impact on stroke. Don't go buying too many heart boxes just yet, though, say the study authors.

A new analysis, which involved a review of three prior studies, suggests eating about a bar of chocolate a week can help cut the risk of stroke and lower the risk of death after a stroke. But the evidence is still limited, says study author, neurologist Gustavo Saposnik at St. Michael's Hospital, University of Toronto.

Cyber Warriors

From The Atlantic:

When will China emerge as a military threat to the U.S.? In most respects the answer is: not anytime soon—China doesn’t even contemplate a time it might challenge America directly. But one significant threat already exists: cyberwar. Attacks—not just from China but from Russia and elsewhere—on America’s electronic networks cost millions of dollars and could in the extreme cause the collapse of financial life, the halt of most manufacturing systems, and the evaporation of all the data and knowledge stored on the Internet.

Evolution On The March

From Philadelphia Inquirer:

New DNA findings show that human genetic mutations are more recent, more rapid than once thought.

Conventional wisdom holds that if you could bring back someone from 40,000 years ago, he or she would blend perfectly well with today's population.

After all, the fossils show that our ancestors were "anatomically modern" by 100,000 years ago, and by 40,000 B.C., they were creating complex tools and art.

It was easy to assume our species hadn't evolved much since then.

Now molecular biology is overturning that assumption.

Scientists Freeze Water With Heat

From Live Science:

Imagine water freezing solid even as it's heating up. Such are the bizarre tricks scientists now find water is capable of.

Popular belief contends that water freezes at 32 degrees Fahrenheit (0 degrees Celsius). Surprisingly, if water lies in a smooth bottle and is free of any dust, it can stay liquid down to minus 40 degrees F (minus 40 degrees C) in what's called "supercooled" form. The dust and rough surfaces that water is normally found in contact with in nature can serve as the kernels around which ice crystals form.

A Menu For Feeding 9 Billion

From New York Times:

Science Magazine has removed the pay wall from “Food Security: The Challenge of Feeding 9 Billion People.” The paper concludes, as many have before, that keeping up with humanity’s needs as numbers and appetites crest toward mid-century poses big challenges. But it expresses optimism that a sustained focus on efficiency, technology and policy innovations can do the trick. (The images above, from the paper, show how investments in water storage and other measures helped restore vegetation in a dry region in Niger.) Here’s the summary:

Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably. A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here.

Google Takes On The Telecoms

From The Wall Street Journal:

Google's decision to build a gigabit-a-second broadband network serving between 50,000 and 500,000 people predictably won plaudits from the Federal Communications Commission and public interest groups. But if Google truly wants to help speed the development of universal high-speed Internet access, as it says, it will need to do much more.

After all, there isn't a huge technical challenge building a fast network. Verizon Communications already is operating one that runs at 2.5 gigabits a second, offering television, Internet and phone. The maximum Internet speed it offers is 50 megabytes per second, but it easily can turn that up. It is spending $23 billion over several years to roll out the network to pass 18 million homes in largely suburban and urban areas.

U.S. Government Wants To Track Its Citizens Through Their Cell Phones

Feds Push For Tracking Cell Phones -- CNET

Two years ago, when the FBI was stymied by a band of armed robbers known as the "Scarecrow Bandits" that had robbed more than 20 Texas banks, it came up with a novel method of locating the thieves.

FBI agents obtained logs from mobile phone companies corresponding to what their cellular towers had recorded at the time of a dozen different bank robberies in the Dallas area. The voluminous records showed that two phones had made calls around the time of all 12 heists, and that those phones belonged to men named Tony Hewitt and Corey Duffey. A jury eventually convicted the duo of multiple bank robbery and weapons charges.

As the blizzard-bound residents of the mid-Atlantic region get ready to dig themselves out of the third major storm of the season, they may stop to wonder two things: Why haven't we bothered to invest in a snow blower, and what happened to climate change? After all, it stands to reason that if the world is getting warmer — and the past decade was the hottest on record — major snowstorms should become a thing of the past, like PalmPilots and majority rule in the Senate. Certainly that's what the Virginia state Republican Party thinks: the GOP aired an ad last weekend that attacked two Democratic members of Congress for supporting the 2009 carbon-cap-and-trade bill, using the recent storms to cast doubt on global warming.
