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.

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.

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.
