Weaponizing oxygen to kill infections and disease
The life-threatening bacteria MRSA can cripple a medical facility since it is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics, instead using light to activate oxygen, which wipes out bacteria. The method also could be used to treat other microbial infections, and possibly even cancer.

A paper battery powered by bacteria
In remote areas of the world, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be too expensive. Today, researchers report a new type of battery -- made of paper and fueled by bacteria -- that could overcome these challenges.

Acid coastal seas off US putting common fish species at risk
Scientists have shown that coastal waters and river estuaries can exhibit unique vulnerabilities to acidification than offshore waters. This acidification, detected in waters off the United States West Coast and the Gulf of Mexico, can lead to disorientation and cognitive problems in some marine fish species, such as salmon, sharks, and cod.

Water-worlds are common: Exoplanets may contain vast amounts of water
Scientists have shown that water is likely to be a major component of those exoplanets (planets orbiting other stars) which are between two to four times the size of Earth. It will have implications for the search of life in our Galaxy.

Making aquafeed more sustainable: Scientists develop feeds using a marine microalga co-product
Scientists have created a more sustainable feed for aquaculture by using a marine microalga co-product as a feed ingredient. The study is the first of its kind to evaluate replacing fishmeal with a co-product in feed designed specifically for Nile tilapia.

Insight into development of lung cancer
Lung cancer results from effects of smoking along with multiple genetic components. A new study identifies two main pathways for the role of chromosome 15q25.1 -- a leader in increasing susceptibility to lung cancer -- in modifying disease risk. One pathway is implicated in nicotine dependence. The other plays a part in biological processes such as nutrient transfer and immune system function. The findings increase our understanding of lung cancer cause and development.

Chemistry professor develops contaminant detection technique for heparin
In 2008, a contaminant eluded the quality safeguards in the pharmaceutical industry and infiltrated a large portion of the supply of the popular blood thinner heparin, sickening hundreds and killing about 100 in the US.

A valley so low: Electrons congregate in ways that could be useful to 'valleytronics'
Researchers have made a finding that could help usher in new area of technology called 'valleytronics.' The study found that electrons in bismuth crystals prefer to collect in one valley rather than being distributed equally across valleys, setting up a type of electricity known as ferroelectricity.
