Optics breakthrough to revamp night vision

Science Daily - Tue, 24/05/2016 - 4:42pm
A breakthrough could make infra-red technology easy-to-use and cheap, potentially saving millions of dollars in defense and other areas using sensing devices for night vision, and boosting applications to a host of new areas, including agriculture. Researchers have demonstrated a dramatic increase in the absorption efficiency of light in a layer of semiconductor only a few hundred atoms thick -- from 7.7 percent currently to almost 99 percent light absorption.

PET imaging with special tracer can detect, diagnose early Alzheimer's disease

Science Daily - Tue, 24/05/2016 - 4:42pm
Recognizing that the use of biomarkers has led to advances in the detection of Alzheimer's disease (AD), researchers reviewed a PET amyloid imaging agent, finding that imaging with PiB provides early detection of disease and allows clinicians to distinguish AD from other dementias. Using this and other agents provides a valuable pathway for investigating the relationship between amyloid pathology and changes in cognition, brain structure, and function.

Coral bleaching 'lifeboat' could be just beneath the surface

Science Daily - Tue, 24/05/2016 - 4:40pm
A report commissioned by the United Nations offers a glimmer of hope to those managing the impact of bleaching on the world's coral reefs, including the Great Barrier Reef. The 35 authors of the United Nations Environmental Programme in-depth report say as the world's surface reefs are being threatened, part of the ecosystem may survive in these barely known deeper environments, known as mesophotic coral ecosystems (MCEs).

Early armored dinosaur from Texas lacked cousin's club-tail weapon, but had a nose for danger

Science Daily - Tue, 24/05/2016 - 4:34pm
First-ever CT scans of the early armored dinosaur Pawpawsaurus campbelli reveal that although the Texas dino lacked its cousin's club-tail it had a sharp nose for danger. A relative of Ankylosaurus, Pawpawsaurus's saving grace from predators may have been an acute sense of smell, says vertebrate paleontologists. Pawpawsaurus lived 100 million years ago, preceding Ankylosaurus by 35 million years. CT scans allow scientists to determine how the animal's brain functioned.

Alcohol exposure during adolescence leads to chronic stress vulnerability

Science Daily - Tue, 24/05/2016 - 4:15pm
Drinking during early to mid-adolescence can lead to vulnerability to chronic stress, according to new research. A research team gave alcohol to rats every other day, starting from early to mid-adolescence. When the team looked at the same rats in adulthood, they found that adult males didn't show hormonal stress adaptation, making them more vulnerable to chronic stress.
