Strontium Isotope Ratios in Fish Otoliths as Biogenic Tracers of Coal Combustion Residual Inputs to Freshwater Ecosystems

A Duke University study shows that trace elements in a fish's ear bones can be used to identify and track coal ash contamination in the waters where it lived. "Calcified structures—or otoliths—found in a fish's inner ear are known to store a lot of life history information,...

Designing Bioinspired Surfaces For Water Collection From Fog

Humans can get by in the most basic of shelters, can scratch together a meal from the most humble of ingredients. But we can't survive without clean water. And in places where water is scarce—the world's deserts, for example—getting water to people requires feats of engineering...

Human ESC-Derived Chimeric Mouse Models of Huntington's Disease Reveal Cell-Intrinsic Defects in Glial Progenitor Cell Differentiation

The neurological disorder Huntington's disease causes behavioural and motor changes, which among other things are a result of dysfunctional maturation or formation of glial cells, the brain's support cells, researchers from the University of Copenhagen demonstrate in a new...

Decline In Climate Resilience Of European Wheat

The climate is not only warming, it is also becoming more variable and extreme. Such unpredictable weather can weaken global food security if major crops such as wheat are not sufficiently resilient—and if we are not properly prepared. A group of European researchers,...

Exposure To Secondhand Smoke And Arrhythmogenic Cardiac Alternans In A Mouse Model

Continuous indoor exposure to second-hand tobacco smoke triggers changes in the heart's electrical activity, known as cardiac alternans, that can predict cardiac arrhythmia and sudden cardiac death, a new study from UC Davis Health researchers shows. The authors believe...

A Dendritic Substrate For The Cholinergic Control Of Neocortical Output Neurons

University of Queensland researchers have discovered a key mechanism in the brain that may underlie our ability to rapidly focus attention. Our brains are continuously bombarded with information from the senses, yet our level of vigilance to such input varies, allowing...

Exercise-Induced Changes In Visceral Adipose Tissue Mass Are Regulated By IL-6 Signaling: A Randomized Controlled Trial

Some of you may have made a New Year's resolution to hit the gym to tackle that annoying belly fat. But have you ever wondered how physical activity produces this desired effect? A signaling molecule called interleukin-6 plays a critical role in this process, researchers...

Discovery Of TeV γ-ray Emission From The Neighbourhood Of The Supernova Remnant G24.7+0.6 By MAGIC

Using MAGIC telescopes and NASA's Fermi spacecraft, an international team of astronomers has discovered a new source of very high energy gamma-ray emission around the supernova remnant (SNR) G24.7+0.6. The detection of the new source, designated MAGIC J1835–069, is detailed...

Beyond The Molecular movie: Dynamics of bands and bonds during a photoinduced phase transition

In a recent publication in Science, researchers at the University of Paderborn and the Fritz Haber Institute Berlin demonstrated their ability to observe electrons' movements during a chemical reaction. Researchers have long studied the atomic-scale processes that govern...

A Novel Alkaliphilic Streptomyces Inhibits ESKAPE Pathogens

Researchers analysing soil from Ireland long thought to have medicinal properties have discovered that it contains a previously unknown strain of bacteria which is effective against four of the top six superbugs that are resistant to antibiotics, including MRSA. Antibiotic-resistant...

Whale Rover Moving Along The Surface Of Sperm Whale

A team of researchers at Yamagata University and Teikyo University of Science, in Japan, have recently developed a new roving biologger, or whale rover, which can travel along a sperm whale's body surface and collect valuable behavioural data. Biologging entails the biological...
