Hot-air balloon rides - researchers advise 'proceed with caution'

Posted: 04 Nov 2013 01:23 PM PST

Investigation of hot-air balloon-related injuries and deaths in the U.S. reports that targeted interventions may improve crash outcomes and decrease the number and severity of balloon crash injuries.

Genetic study demonstrates Israel's wild boars originated in Europe

Posted: 04 Nov 2013 12:27 PM PST

Scientists had no reason to suspect Israeli wild boars were any different than their brothers and sisters roaming the Middle East. Now, a researcher demonstrates that, unlike the Near Eastern wild boars in surrounding countries, Israel's wild boars originated in Europe, brought to Israel starting almost 3,000 years ago by the Philistines and other seafaring raiders.

How common are habitable planets? One in five stars may have Earth-size, potentially habitable planets

Posted: 04 Nov 2013 12:27 PM PST

Astronomers analyzed all four years of Kepler data in search of Earth-size planets in the habitable zones of sun-like stars, and then rigorously tested how many planets they may have missed. Based on this analysis, they estimate that 22 percent of stars like the sun have potentially habitable Earth-size planets, though not all may be rocky or have liquid water, a presumed prerequisite for life.

Fossil of largest known platypus discovered in Australia

Posted: 04 Nov 2013 12:27 PM PST

Until recently, the fossil record indicated that the platypus lineage was unique, with only one species inhabiting the Earth at any one time. This picture has changed with the spectacular find of a new, giant species of extinct platypus that was a side-branch of the platypus family tree.

Physicist discovers black holes in globular star clusters, upsetting 40 years of theory: Could there be ripples in spacetime?

Posted: 04 Nov 2013 12:26 PM PST

An astrophysicist was part of a team of researchers that discovered the first examples of black holes in globular star clusters in our own galaxy, upsetting 40 years of theories against their possible existence.

Fishy behavior solves an animal locomotion mystery

Posted: 04 Nov 2013 12:25 PM PST

The puzzling, apparently wasteful habit of some animals to exert force in the direction opposite of where they want to go actually has an important purpose: to increase both stability and maneuverability.

Snakes control blood flow to aid vision

A new study shows that snakes can optimize their vision by controlling the blood flow in their eyes when they perceive a threat.

Quantum 'sealed envelope' system enables 'perfectly secure' information storage

Posted: 04 Nov 2013 07:12 AM PST

Breakthrough guarantees "unconditional" security of information by harnessing quantum theory and relativity, and has been successfully demonstrated on a global scale for the first time.

Lasers might lead to cure for brain diseases such as Alzheimer's and Parkinson's

Posted: 03 Nov 2013 11:03 AM PST

Researchers have made a discovery that may lead to the curing of diseases such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease (the so called mad cow disease) through photo therapy.
