When, where and how is ice formed in northern streams?

Ice formation is important in northern streams with long winters as it affects plants and animals in various ways. But knowledge on variations in ice formation processes has been inadequate. Former doctoral student, Lovisa Lind, at Umeå...Show More Summary

Cells migrate collectively by intermittent bursts of activity

Cell migration is a central process in the development and maintenance of multicellular organisms. Researchers of Aalto University and their research partners have now discovered that this motion occurs by intermittent bursts of activity. It can be described by universal scaling laws similar to the ones observed in other driven systems outside of biology.

Wild grass species found unable to adapt rapidly enough to survive global warming

(Phys.org)—A trio of researchers with the University of Arizona has found evidence that suggests many wild grass species will be at risk of disappearing from certain areas as the planet heats up. In their paper published in the journal...Show More Summary

Pesticide predicament for California's strawberry growers

The powerful fumigant methyl bromide will be retired from California's strawberry fields at the end of this year after more than 20 years of fierce debate over its effects and alternatives.

Cocaine accumulation in fish eyes

A study by Eawag and Zurich University researchers using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals – especially psychoactive drugs – needShow More Summary

Researchers get mixed results in training dogs to sniff out lung cancer in humans

(Phys.org)—A team of researchers at Krems University Hospital in Vienna Austria has found mixed results while conducting studies to determine the viability of using dogs to detect lung cancer in human beings. In their paper published...Show More Summary

Missions CARIOCA – Papouasie-Nouvelle-Guinée – Acclimatation des coraux à l’acidification des océans (in French)

Une équipe internationale pilotée par l’IRD embarque à bord de l’Alis pour étudier en Papouasie-Nouvelle-Guinée des espèces de coraux capables de se développer dans des sites naturellement plus acides. Objectif : en savoir plus sur leur...Show More Summary

A direct CO2 control system for ocean acidification experiments: testing effects on the coralline red algae Phymatolithon lusitanicum

Most ocean acidification (OA) experimental systems rely on pH as an indirect way to control CO2. However, accurate pH measurements are difficult to obtain and shifts in temperature and/or salinity alter the relationship between pH and pCO2. Here we describe a system in which the target pCO2 is controlled via direct analysis of pCO2 in […]

Ocean Acidification “State of the Science” Workshop, 30 November – 1 December 2016, Anchorage, Alaska

Mystery Zika case in Utah may have been spread via tears or sweat

Experts examine whether virus can be passed on in sweat or tears after man appears to catch Zika at father’s bedside Experts are investigating the possibility that the Zika virus can be passed on in sweat or tears, after the infection of a 38-year-old man in the US who appears to have caught the virus at his father’s hospital bedside.

Gecko study offers evidence that small morphological changes can lead to large changes in function

How do key innovations in the animal kingdom arise? To explore this question, gecko expert Timothy Higham, an associate professor of biology at the University of California, Riverside, led a team of evolutionary biologists to study Gonatodes, a genus of dwarf geckos. Show More Summary

Vital interplay between microorganisms and extracellular minerals

Some minerals abundant in soils and in aquatic and subsurface sediments electronically support microbial growth by supplying electrons or storing them as "environmental batteries," according to this new review article. Microbial cells...Show More Summary

Wind turbines killing more than just local birds, study finds

Wind turbines are known to kill large birds, such as golden eagles, that live nearby. Now there is evidence that birds from up to hundreds of miles away make up a significant portion of the raptors that are killed at these wind energy fields.

Drug manufacturers need to understand how their products affect entire biological networks

Decoys in DNA may serve a larger purpose than drug designers suspect, according to Rice University scientists.

Researchers find way to ID many pathogens with few DNA probes

Rice University scientists have invented a technology that could potentially identify hundreds of bacterial pathogens simply, quickly and at low cost using a single set of random DNA probes. Rice's "universal microbial diagnostic," or...Show More Summary

Scientists reveal how signals from pathogenic bacteria reach danger sensors of cells

Researchers at St. Jude Children's Research Hospital have discovered the way signals from infectious bacteria gain entry into the cytoplasm of host cells to activate disease-fighting inflammasomes. Inflammasomes are protein machinesShow More Summary

Cellphones spill into Yellowstone's wilds despite park plan

Adventure seekers encounter untamed wilderness when they enter the backcountry of Yellowstone National Park. Howling wolves. Deadly grizzly bears. Steam-spewing geysers as seen nowhere else on earth.

Researchers create technique for opening insects' exoskeletons to study living cells

Scientists believe that hearing in fruit flies and in humans is remarkably similar at the cellular level, which is why they'd like to explore the fruit fly's ear to learn more about how humans hear.
