New Super-Heavy Element Discovered That Points Towards 'Strange Materials Of The Future'
Physicists have discovered a new super-heavy element that had been labeled a nuclear 'missing link' by scientists.
The element 117 is roughly 40 per cent heavier than lead and has been given the temporary name ununseptium, which refers to its atomic number.
Researchers believe the element points towards a concoction of more massive and stable elements that could be used to create strange and unpredictable new materials.

First Footage From World's Deepest Volcanic Vents
From New Scientist:
At this depth, the water is hot enough to melt lead, and the pressure it exerts means that every square centimetre has to withstand the weight of five hefty men.
"It was like wandering across the surface of another world," says Bramley Murton, a geologist at the National Oceanographic Centre (NOC) in Southampton, UK, who piloted the Hy-Bis underwater vehicle around these deep volcanic vents and filmed them for the first time.

Happy 50th Birthday To The Search For Extraterrestrial Intelligence!
From Popular Science:
Celebrating half a century of no aliens
Fifty years ago today, on April 8th, 1960, a Cornell astronomy professor named Frank Drake pointed a radio telescope at the star Tau Ceti in the hope of hearing broadcasts from extraterrestrial intelligence. Naturally, he didn't hear anything out of the ordinary. But with this experiment, Drake began the decades-long search for aliens, known as the Search for Extraterrestrial Intelligence (SETI), that celebrates its 50th anniversary today. Over the last half century, SETI has failed at its initial goal of contacting aliens, but succeeded mightily in bringing new attention to astronomy, helping to develop cloud computing, and inspiring generations of new scientists.

'World Needs A Barometer Of Life'
The world needs a "barometer of life" to prevent ecosystems and species being lost forever, scientists have warned.
Existing schemes, they said, did not include enough species from groups such as fungi and invertebrates to provide a detailed picture of what is at risk.
Writing in the journal Science, the researchers said the barometer would increase the number of species being assessed from almost 48,000 to 160,000.
The data would help identify areas in need of urgent action, they added.

US Launches Agency To Monitor Evereyone
All hail BIMA, the new U.S. biometrics agency.
Collecting fingerprints and other biometric data has long allowed law enforcement and the military alike to track down wanted individuals, solve cases, or just keep tabs on people. Now what was a U.S. government task force under the U.S. Army has officially become a full-scale national security agency in charge of biometrics, according to the Secrecy News blog run by the Federation of American Scientists.

Picking Our Brains: Can Ee Regenerate The Brain?
From New Scientist:
YOU were born with all the brain cells you'll ever have, so the saying goes.
So much for sayings. In the 1990s, decades of dogma were overturned by the discovery that mammals, including people, make new neurons throughout their lives. In humans, such "neurogenesis" has been seen in two places: neurons formed in the olfactory bulb seem to be involved in learning new smells, while those born in the hippocampus are involved in learning and memory.

Bats Could Inspire New Radar Systems
From The Telegraph:
Bats which have evolved to avoid having their echo signals blocked by interference could help scientists develop more efficient sonar and radar systems.
Bats emit high-pitched sounds to locate obstacles and prey as they fly, but when travelling in packs there is a risk the noises might overlap and interfere.
A similar problem arises when a bat chases a moth through thick foliage. Signals bouncing off the leaves can overlap and set up interference.

Better Military Technology Does Not Lead to Shorter Wars, Analysis Reveals
From Science Daily:
ScienceDaily (Mar. 31, 2010) — It is generally assumed that military technology that is offensive rather than defensive in nature leads to shorter wars. Yet, a new doctoral thesis from the University of Gothenburg, Sweden, shows that this assumption is not correct.
For long, researchers have thought that offensive military technology, such as armoured cars and attack jets, makes it easier to shorten the duration of a war. It is also generally perceived that when the offensive technology is more effective than the defensive technology, it is more advantageous to start a war.

Which States Pay Highest Gas Prices
Gas Prices as a percent of income varies by state. See how each state fares. Credit: Karl Tate/LiveScience
From Live Science:
Everyone grumbles when prices at the pump rise, but some drivers pay more depending on where they live. A new study shows how gas price spikes hurt the wallets of drivers in some states more than in others.
On average, Mississippi drivers spent more than 6 percent of their annual income on gas in 2009, compared to drivers in Connecticut and New York who spent just 2.5 percent of their income on gas. But a price spike similar to the one in July 2008 would have worsened the imbalance — Mississippi drivers would have seen driving costs shoot up to 11 percent as opposed to just 4.3 percent for Connecticut and New York.

On June 1, 2009, Air France Flight 447 disappeared in turbulent weather en route from Rio de Janeiro to Paris. For the remainder of the summer, two major efforts were launched by search and rescue crews to find the remains of the plane and the 228 people who had been on board, with great hopes of also finding the two data recorders. So far, 51 bodies and 1,000 pieces of wreckage have been found, but not the data recorders, which only emit signals for 30 days.
Finding the so-called black boxes is key to understanding what happened to the airplane.

From ABC News:
Cinnamon and Ginseng Stretch Life of a Worm; Will They Stretch Yours?
Most Americans have used herbal drugs during the past year, even though in nearly all cases there is no clear scientific evidence that they work. Now, an international team of scientists has found a way to collect that evidence, and even determine which components of very complex compounds are doing the work, and which aren't.

Mobile Nuclear Reactors Could Provide Power And Jet Fuel For Military, DARPA Says
From Popular Science:
Making U.S. Navy carrier groups and Army bases more self-sufficient and energy-efficient could mean turning to mobile nuclear reactors. The Pentagon's DARPA scientists have put forth the modest proposal of deploying miniature reactors to convert hydrogen and carbon into military jet fuel, as well as providing power, The Register reports.

Oceanology: Tethered Antenna Keeps Subs In Touch
From New Scientist:
ROBOTIC submarines have always had trouble when it comes to picking up GPS signals and communicating with their operators. That's because radio signals do not travel far underwater. If the submarines do not surface regularly in order to check their position, they run the risk of drifting off-course.
This problem could now be solved, thanks to a wing-like antenna that piggybacks on small submarines. The antenna ascends to the surface on a tether as and when needed, enabling satellite communications, including GPS readings. It can even carry a camera to serve as a kind of periscope for the sub's controller.

The Male Brain: More Complex Than You Think
From Time Magazine:
Despite all that old talk about Mars and Venus, men and women are much more biologically alike than not. But differences in the way our brains are built shed light on everything from the way we flirt to the way we fight to how we raise our boys, says neuropsychiatrist Dr. Louann Brizendine in her provocative new book, The Male Brain. The author talked to TIME about sex, the daddy brain and why some men may be built to cheat.

Orca The Dolphin Killer
From The Daily Mail:
This is the shocking moment a killer whale leapt from the sea to kill an exhausted dolphin.
The six-ton hunter had chased the female dolphin through the waves before swimming up under her and slamming into her, flipping her 30 feet into the air and breaking her back.
The dolphin died almost instantly and the killer whale, or orca, and the rest of its pod then closed in to devour her and her helpless youngster, turning the sea red.
