A Blood Test For Depressions

Blood Test Could Someday Diagnose Depression. U.S. Navy

Study Of The Day: Blood Tests Can Accurately Diagnose Depression -- The Atlantic

PROBLEM: Depression has traditionally been diagnosed with a questionnaire that assesses patients' reported symptoms. This process varies greatly, however, since it relies heavily on the clinician's experience and resources.

METHODOLOGY: To test if an objective biological test could improve diagnosis accuracy, scientists recruited 36 adults with major depression and 43 healthy participants for a blood screening. They measured the levels of nine biomarkers associated with depressive symptoms, such as inflammation, the development and maintenance of neurons, and the interaction between brain structures involved with stress response and other key functions.

Nanodust Explosives?



Dust Causes Explosions, And Apparently Nanodust Causes Mega-Explosions -- Popular Science

Along with annoyingly adhering to your TV screen and tabletops, dust can be a deadly material, exploding with enormously destructive force in places like coal mines, sugar refineries and grain silos. The explosive properties of normal dust are pretty well known, but what about non-traditional dust? Not all dusts are created equal — and dust derived from the materials of the future could present a very different type of danger.

A Bill Of Rights For Dolphins?

Flippin' heck: A coalition of scientists are calling for a bill of rights to protect dolphins like bottlenose Fungie who loves to entertain sightseers in boats in Dingle, Ireland

A Bill Of Rights For Dolphins: They're So Smart We Must Treat Them As 'Non Human Persons' Say Scientists -- Daily Mail

Dolphins are so intelligent that they should be thought of as ‘non-human persons’ and given their own bill of rights, it is claimed.

A coalition of scientists, philosophers and animal welfare groups have come up with a declaration of dolphin rights which they hope will one day be enshrined in law.

This would stop them being kept in zoos and waterparks, and being attacked by fishermen.

Its Been 50 Years Since John Glenn Circled The Earth


50 Years Later, Celebrating John Glenn’s Feat -- New York Times

In the winter of 1962, the nation needed a hero.

Americans had yet to recover from the Soviet Union’s launching of the first spacecraft, Sputnik, in October 1957 — a rude jolt to our confidence as world leaders in all things technological. The space race was on.

Soon after he took office in 1961, President John F. Kennedy had thrown down the challenge to send men to the Moon by the end of the decade. But the Russians still set the pace, boastfully. They launched a dog into orbit, then the first man, Yuri A. Gagarin, and another, Gherman S. Titov.

The United States lagged, managing only two 15-minute suborbital astronaut flights — only five minutes of weightlessness each time.

New Formula One Cars

2012 Ferrari Formula one car.

Formula One Gets Ugly -- Sydney Morning Herald

In 1954 Ferrari produced the 553 Squalo, an aggressive, thrusting Formula one car named in Italian for the shark it resembled. In 1962, it released a road car called 250 GT Lusso, or Italian for "beautiful".

For 2012, Ferrari has given us the less evocatively named Platypus. Or rather, almost the entire F1 field has earned the sobriquet thanks to their misshapen, stepped nose sections that promise some of the ugliest-looking Formula one cars in years. F1ugly, in fact.

The Search For Dark Energy


The Dark Side Of The Universe -- The Economist

Scientists are trying to understand why the universe is running away from them.

AT FIVE tonnes and 520 megapixels, it is the biggest digital camera ever built—which is fitting, because it is designed to tackle the biggest problem in the universe. On February 20th researchers at the Cerro Tololo Inter-American Observatory (pictured), which sits 2,200 metres (7,200 feet) above sea level in the Atacama desert of northern Chile, will begin installing this behemoth on a telescope called Blanco. It is the centrepiece of the Dark Energy Survey (DES), the most ambitious attempt yet to understand a mystery as perplexing as any that faces physics: what is driving the universe to expand at an ever greater rate.

Will Diseases Soon Become 'Impossible To Treat'?

Experts Fear Diseases 'Impossible To Treat' -- The Independent

Alarming rise in bacteria resistant to antibiotics, Government report finds.

Britain is facing a "massive" rise in antibiotic-resistant blood poisoning caused by the bacterium E.coli – bringing closer the spectre of diseases that are impossible to treat.

Experts say the growth of antibiotic resistance now poses as great a threat to global health as the emergence of new diseases such as Aids and pandemic flu.

Professor Peter Hawkey, a clinical microbiologist and chair of the Government's antibiotic-resistance working group, said that antibiotic resistance had become medicine's equivalent of climate change.

Project Avatar


Project Avatar: U.S. Military Researches Ways For Soldiers To Control Robot 'Surrogates' Using Just Their Minds -- Daily Mail

The U.S. military is researching ways for its troops can use their minds to remotely control androids who will take human soldiers' place on the battlefield.

The Defense Advanced Research Projects Agency (Darpa), the Pentagon's hi-tech research arm, has earmarked $7million for research into the project, nicknamed Avatar.

The ultimate goal of the project sounds, bizarrely, much like the fantastical plot of the the film of the same name.

Despite Bio-Terrorism Fears, H5N1 Research Will Be 'Eventually' Published

An image taken through an electronic microscope of the H5N1 virus, also known as the "bird flu." Virologist Ron Fouchier of the Erasmus Medical Center in Rotterdam has developed a new mutation of the H5N1 virus. Outside the lab, the disease has only been transmitted from animals to humans. Fouchier's mutation makes it airborne, creating the possibility of human-to-human transmission. CDC / dapd

WHO Delays Hugely Significant Decision On Whether To Publish Details Of Lethal Man-Made Flu That Could Kill Half The People It Infects -- Daily Mail

* H5N1 bird flu virus kills half of humans that contract it
* Research into more contagious forms of virus
* Editor says 'we have to publish in complete form'
* Insists publication is essential to create vaccine

The World Health Organisation has delayed its decision as to whether controversial research into a dangerous new man-made mutant form of the bird flu virus should be made public.

Scientists, health officials and science journal editors have this week been locked in talks on whether the study should be released amid fears it could be exploited by bioterrorists.

The controversial research shows how to make a mutant strain of the H5N1 virus, which kills roughly half of those who contract it, more contagious.

Are Ocean Plankton Impacting Earth's Climate?

Maria Maldonado of the University of British Columbia argues that understanding the chemistry of phytoplankton is key to controlling Earth's climate

Are Ocean Plankton The Key Ingredient That Decides The Future Of Earth's Climate? -- Daily Mail

* Phytoplankton provide half planet's oxygen
* Can soak up 45 billion tons of carbon dioxide per year
* CO2 'buried' in deep ocean for centuries
Tiny ocean 'phytoplankton' have a huge impact on Earth's climate - and understanding them could be key to the planet's future health.

Canadian scientist Maria Maldonado is researching why the phytoplankton thrive in some areas, and how they survive in areas with hostile conditions.

The tiny single-celled algae soak up 45 billion tons of carbon dioxide every year - transferring 16 billion tons to the deep ocean. They provide half the planet's oxygen supply.

Understanding them is vital to understanding - and regulating - our planet's health, Maldonado says.

Tweaking The Fracking Process To Prevent Environmental Damage

Men with Cabot Oil and Gas work on a natural gas valve at a hydraulic fracturing site in South Montrose, Penn. Hydraulic fracturing, also known as fracking, stimulates gas production by injecting wells with high volumes of chemical-laced water in order to free up pockets of natural gas below.

It's Not Fracking's Fault, Study Says -- MSNBC

A university study asserts that the problems caused by the gas extraction process known as hydraulic fracturing, or "fracking," arise because drilling operations aren't doing it right. The process itself isn't to blame, according to the study, released today by the Energy Institute at the University of Texas at Austin.

The report is likely to add new fuel to a blazing controversy over fracking. Researchers reviewed the evidence contained in the reports of groundwater contamination from three prominent shale-rock formations where the process is employed: the Barnett Shale in North Texas, the Marcellus Shale in Pennsylvania, New York and other areas of Appalachia; and the Haynesville Shale in western Louisiana and northeast Texas.

Tight oil, the new oil source unlocked by new drilling technologies, is bearing such good results it could quickly compete with Canada’s oil sands as a top secure supply of North American oil.

With companies like Devon Energy Corp., Talisman Energy Inc., Encana Corp., Exxon Mobil Corp. pushing big spending toward tight oil, analysts are ratcheting up their production forecasts for the supplies, which are largely based in the United States.

“Tight oil is changing the landscape in North America,” Steve Fekete, managing consultant at Purvin & Gertz, said at an oil sands industry conference in Calgary this week.

Nanosecond Trading Could Make Markets Go Haywire -- Wired

The afternoon of May 6, 2010 was among the strangest in economic history. Starting at 2:42 p.m. EDT, the Dow Jones stock index fell 600 points in just 6 minutes. Its nadir represented the deepest single-day decline in that market’s 114-year history. By 3:07 p.m., the index had rebounded. The “flash crash,” as it came to be known, was big, unexpected and scary — and a new study says flash events actually happen routinely, at speeds so fast they don’t register on regular market records, with potentially troubling consequences for market stability.

Could Hurricanes Wreck $700m Offshore Wind Farms In U.S.? Experts Predict HALF Of Proposed Turbines Will Be Ruined In 20 Years -- Daily Mail

* Pittsburgh researchers' study follows up on U.S. energy report in 2008
* Energy officials want wind farms to generate 20% of electricity by 2013
* Plans for farms in Massachusetts, New Jersey, North Carolina & Texas
* Experts say current design can only withstand Category 3 hurricanes
U.S. energy officials have set a bullish target for wind farms to generate one fifth of the country’s electricity by 2030 - but Mother Nature certainly isn’t going to make it easy.

Academic experts at Carnegie Mellon University in Pittsburgh, Pennsylvania, say half of the turbines at four proposed offshore wind farms are likely to be destroyed by hurricanes in their 20-year life.

The proposed wind farms at Massachusetts, New Jersey, North Carolina and Texas could cost $175million each, but the researchers believe current designs of turbines mean many will not survive.
