From Science Daily:

ScienceDaily (Jan. 4, 2010) — DNA that is left in the remains of long-dead plants, animals, or humans allows a direct look into the history of evolution. So far, studies of this kind on ancestral members of our own species have been hampered by scientists' inability to distinguish the ancient DNA from modern-day human DNA contamination.

Mankind's Greatest Explorations And Adventures

Corbis

From Time Magazine:

From the Moon to Mount Everest, our list of the greatest leaps and highest climbs in human history.

The crew of Apollo 11 faced risks that were literally out of this world. Engine failure could have left them stranded on the lunar surface or forever lost in space. Solar radiation and re-entry heat could have cooked them alive. A space-suit failure could have suffocated them in the most gruesome way. By today's standards, Apollo 11's technology was primitive — the onboard navigation computer contained only 74 kilobytes of memory, not enough to store a single MP3 music file. But as soon as Neil Armstrong took his first tentative step on the lunar surface, the risks were forgotten. For an all-too-brief moment, everyone on the planet was caught up in the thrill of human achievement, of a millennia-old fantasy come to life. Other lunar explorers would follow, but Apollo 11 was the first to take the giant leap for mankind.

Genetically modified rice cleared for commercial sale could be growing on Chinese farms as early as next year, making China the first country to allow commercial cultivation of GM strains. The field trials required for any new variety are now under way, following official safety clearance November.

Two varieties, called Huahui 1 and Bt Shanyou 63, received clearance and should be launched within the next two years. Both contain "Bt" proteins from the Bacillus thuringiensis bacterium to protect them against the rice stem borer, the most serious rice pest in China.

10 Sci-Fi Weapons That Actually Exist

Behold the Laser Avenger, a cannon that could be used to take down incoming aircraft. Boeing was able to shoot a drone out of the sky with the hummer-mounted laser, even though it’s not particularly high-powered. It cooked the remote-controlled aircraft using a somewhat feeble 1-kilowatt beam. More recently, the company shot down another UAV using a low-power laser paired with its Mobile Active Targeting Resource for Integrated eXperiments, or Matrix, system during a test in White Sands, New Mexico.

From The Danger Room:

Sure, the gear may look like it came straight out of Avatar or Battlestar Galactica. But all of the laser weapons, robots, sonic blasters and puke rays pictured here are real. Some of these weapons have already found their way onto the battlefield. If the rest of this sci-fi arsenal follows, war may soon be unrecognizable.

From Technology Review:

We already have the technology for discovering hidden explosives, but it could lead to long lines.

The bomb that Umar Farouk Abdulmutallab reportedly tried to set off as his flight neared Detroit on Christmas could have been detected using existing screening technologies, had they only been used. Not only could the explosives have been spotted using back-scatter X-rays or millimeter wave technology--which can see through clothes--invisible traces of the explosive could have been detected using chemical sensors. But both technologies, if used to screen all passengers, would lead to long lines at airport security checkpoints.

Global Warming ALERT: British Experts Predicting Coldest Winter In 100 Years

From YID With LID:

Word to the British, you better buy a new winter coat. Experts are predicting that this will be one of the coldest winters in the past 100 years. This kind of weather was predicted by scientist, Mojib Latif who back in September predicted that earth was going to cool off for the next 20-30 years. Latif said the cooling would be the result of changes to ocean currents and temperatures in the North Atlantic, a feature known as the North Atlantic Oscillation (NAO) and the NAO may be partly the cause of warming during the past 30 years.

Its ironic that in Britain, home of the Climate Research Unit of the University of East Anglia, recently made famous by the climategate is facing one of the coldest winters in 100 years, experts predict temperatures hitting minus 16 degrees Celsius (+3 Fahrenheit).

The Royal Society formed on a dreary night in London 350 years ago, when the acquisition of scientific knowledge was little more than a hobby for amateurs and polymaths. As part of the celebrations, world-leading researchers have been invited to Britain to thrash out the most pressing questions facing science today: what is consciousness? Where did the universe come from? How are we ever going to feed everybody? Whatever the scientists decide, it will reflect the agenda for the next two decades.

What And When Is Death?

From The New Atlantis:

All living things die. This is not new and it has nothing to do with technology. What is new in our technological age, however, is an uncertainty about when death has come for some human beings. These human beings, as an unintended consequence of efforts to prevent death, are left suspended at its threshold. Observing them in this state of suspension, we, the living, have a very hard time knowing what to think: Is the living being still among us? Is there still a present for this person or has the long reign of the past tense begun: Is he or was he? The phenomenon is popularly known as “brain death,” but the name is misleading. Death accepts no modifiers. There is only one death. Has it occurred or not? Alive or dead?

No Rise of Atmospheric Carbon Dioxide Fraction In Past 160 Years, New Research Finds

Science Daily (Dec. 31, 2009) — Most of the carbon dioxide emitted by human activity does not remain in the atmosphere, but is instead absorbed by the oceans and terrestrial ecosystems. In fact, only about 45 percent of emitted carbon dioxide stays in the atmosphere.

However, some studies have suggested that the ability of oceans and plants to absorb carbon dioxide recently may have begun to decline and that the airborne fraction of anthropogenic carbon dioxide emissions is therefore beginning to increase.
