Birth of planets revealed in astonishing detail in ALMA’s 'best image ever' Posted: 06 Nov 2014 05:20 AM PST Astronomers have captured the best image ever of planet formation around an infant star as part of the testing and verification process for the Atacama Large Millimeter/submillimeter Array's (ALMA) new high-resolution capabilities.

Direct brain interface between humans Posted: 05 Nov 2014 12:45 PM PST Researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team's initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person's brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.

Humans, baboons share cumulative culture ability Posted: 05 Nov 2014 11:10 AM PST The ability to build up knowledge over generations, called cumulative culture, has given humankind language and technology. While it was thought to be limited to humans until now, researchers have recently found that baboons are also capable of cumulative culture.

Milestone in accelerating particles with plasma: Technique is powerful, efficient enough to drive future particle accelerators Posted: 05 Nov 2014 10:19 AM PST Scientists have shown that a promising technique for accelerating electrons on waves of plasma is efficient enough to power a new generation of shorter, more economical accelerators. This could greatly expand their use in areas such as medicine, national security, industry and high-energy physics research.

Genesis of genitalia: We have one. Lizards have two. Why? Posted: 05 Nov 2014 10:19 AM PST When it comes to genitalia, nature enjoys variety. Snakes and lizards have two. Birds and people have one. And while the former group's paired structures are located somewhat at the level of the limbs, ours, and the birds', appear a bit further down. In fact, snake and lizard genitalia are derived from tissue that gives rise to hind legs, while mammalian genitalia are derived from the tail bud. But despite such noteworthy contrasts, these structures are functionally analogous and express similar genes. Researchers have now discovered how functionally analogous genitalia can arise from divergent tissue.

First amphibious ichthyosaur discovered, filling evolutionary gap Posted: 05 Nov 2014 10:19 AM PST The first fossil of an amphibious ichthyosaur has been discovered in China. The fossil represents a missing stage in the evolution of ichthyosaurs, marine reptiles from the Age of Dinosaurs about 250 million years ago.

Giant groundhog-like creature: Newly discovered fossil is a clue to early mammalian evolution Posted: 05 Nov 2014 10:19 AM PST A newly discovered 66–70 million-year-old groundhog-like creature, massive in size compared to other mammals of its era, provides new and important insights into early mammalian evolution.

Brain dissociates emotional response from explicit memory in fearful situations Posted: 05 Nov 2014 08:26 AM PST Researchers have been tracking the traces of implicit and explicit memories of fear in human. The study describes how in a context of fear, our brain differently encodes contextual memory of a negative event (the place, what we saw ...) and emotional response associated.

High-fat diet postpones brain aging in mice Posted: 05 Nov 2014 08:26 AM PST New research suggests that signs of brain aging can be postponed in mice if placed on a high-fat diet. In the long term, this opens the possibility of treatment of children suffering from premature aging and patients with Alzheimer's and Parkinson's disease.

Jet-fueled electricity at room temperature: Fuel cell can run without high heat Posted: 05 Nov 2014 05:37 AM PST Engineers have now developed the first room-temperature fuel cell that uses enzymes to help jet fuel produce electricity without needing to ignite the fuel. These new fuel cells can be used to power portable electronics, off-grid power and sensors.

Genetic markers for alcoholism recovery discovered Posted: 04 Nov 2014 10:11 AM PST Researchers have identified genetic markers that may help in identifying individuals who could benefit from the alcoholism treatment drug acamprosate. The findings show that patients carrying these genetic variants have longer periods of abstinence during the first three months of acamprosate treatment.

Why anesthetics cause prolonged memory loss Posted: 03 Nov 2014 04:21 PM PST Researchers have shown why anesthetics can cause long-term memory loss, a discovery that can have serious implications for post-operative patients.

'Mild' control of systolic blood pressure in older adults is adequate: 150 is good enough Posted: 03 Nov 2014 11:23 AM PST A broad review of the use of medications to reduce blood pressure has confirmed that 'mild' control of systolic pressure is adequate for adults age 65 or older -- in the elderly, there's no clear benefit to more aggressive use of medications to achieve a lower pressure.

Device developed for running shoes that prevents injuries Posted: 30 Oct 2014 08:48 AM PDT A prototype running shoe has been designed with an integrated device that improves training management and prevents injuries. The device consists of a microelectronic measuring system capable of gathering biomechanical parameters that characterize the runner's technique during a race. This information is wirelessly transmitted to the runner's mobile phone and a mobile phone application provides real-time feedback, including level of performance and suggestions to change the running pattern or to stop running in case of detecting a high risk of injury.
