Pico-world of molecular bioscavengers, mops and sponges being designed
- ScienceDaily
- 13/9/6 02:30
A new world of molecular bioscavengers, sponges and mops is now closer. A computer-design method has enabled scientists to build proteins that can recognize and interact with small molecules. The proteins can also be reprogrammed to detect and unite with related substances, such as different forms of steroids. The method might also become a way to give organisms new tools to perform biological...
Study expands use of biomarker for early diagnosis of acute kidney injury
- ScienceDaily
- 13/9/6 02:30
A biomarker test developed initially to identify early acute kidney injury after surgery has been shown to successfully detect it in emergency room patients with a variety of urgent health issues. The findings expand the overall utility and potential medical settings for using the test, according to...
'Making music may improve young children's behavior'
- ScienceDaily
- 13/9/6 02:28
Making music can improve both pro-social behavior (voluntary behavior intended to benefit another) and the problem solving skills of young children according to a new study. Building on existing research which found that making music significantly improves pro-social behavior in young children) the current study investigated not only the potential effects of music making (singing or playing an...

Prosopagnosia (face blindness) may be temporarily improved following inhalation of the hormone oxytocin.
Newly discovered tiger shark migration pattern might explain attacks near Hawaii
- ScienceDaily
- 13/9/6 02:28
The migration of mature female tiger sharks during late summer and fall to the main Hawaiian Islands, presumably to give birth, could provide insight into attacks in that area, according to scientists.

Blue-green algae a five-tool player in converting waste to fuel
- ScienceDaily
- 13/9/5 22:05
Scientists are working with Synechocystis 6803 -- as well as other microbes and systems -- in the areas of synthetic biology, protein engineering and metabolic engineering, with special focus on synthetic control systems to make the organism reach its untapped prowess. They say the biotech world has to overcome several challenges to put the engineered microbes in the applications...
Coldest brown dwarfs blur lines between stars and planets
- ScienceDaily
- 13/9/5 22:05
Astronomers are constantly on the hunt for ever-colder star-like bodies, and two years ago a new class of such objects was discovered. However, until now no one has known exactly how cool their surfaces really are -- some evidence suggested they could be room temperature. A new study shows that while these brown dwarfs, sometimes called failed stars, are warmer than previously thought with...

Finally mapped: The brain region that distinguishes bits from bounty
- ScienceDaily
- 13/9/5 20:28
In comparing amounts of things -- be it the grains of sand on a beach, or the size of a sea gull flock inhabiting it -- humans use a part of the brain that is organized topographically, researchers have finally shown. In other words, the neurons that work to make this "numerosity" assessment are laid out in a shape that allows those most closely related to communicate and interact over the...
