Canary in a coal mine: Survey captures global picture of air pollution’s effects on...

Writing Aug. 11 in the journal Environmental Research Letters, University of Wisconsin-Madison Professor Tracey Holloway, an expert on air quality, and her former graduate student Olivia Sanderfoot sort through nearly 70 years of the scientific literature to assess the state of knowledge of how air pollution directly affects the health, well-being, reproductive success and diversity of birds.

Night vision for bird- and bat-friendly offshore wind power

ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help birds and bats near offshore wind turbines.

Chemical profile of ants adapts rapidly

Biologists recently established that ants can adapt their hydrocarbon profile quickly during the course of evolution and rapidly adapt to external selection pressures.

Jackdaws flap their wings to save energy

For the first time, researchers have observed that birds that fly actively and flap their wings save energy. Biologists have now shown that jackdaws minimize their energy consumption when they lift off and fly, because the feathers on their wing tips create several small vortices instead of a single large one. The discovery could potentially be applied within the aeronautical industry.

Material-independent nanocoating antimicrobial spray extends the shelf life of produce

Scientists have developed a sprayable nanocoating technique using plant-derived polyphenol that can be applied to any surface. This new nanocoating process can be completed in seconds to form nanometer-thick films, allowing for the coating of commodity goods, such as shoe insoles and fruits, in a controlled fashion.

How goldfish make alcohol to survive without oxygen

Scientists have uncovered the secret behind a goldfish's remarkable ability to produce alcohol as a way of surviving harsh winters beneath frozen lakes.

Small molecule inhibitor prevents or impedes tooth cavities in a preclinical model

Researchers have created a small molecule that prevents or impedes tooth cavities in a preclinical model. The inhibitor blocks the function of a key virulence enzyme in an oral bacterium, a molecular sabotage that is akin to throwing a monkey wrench into machinery to jam the gears.

Archaeologists uncover 3,000-year-old female statue at citadel gate complex in Turkey

The remains of a majestic female statue uncovered at an archaeological site in southeast Turkey may challenge our understanding of the public role of women in the ancient world. Excavations at a site near the Syrian border have unearthed a beautifully carved head and upper torso of a female figure. The remnants are largely intact, although the face and chest appear to have been intentionally -- possibly ritually -- defaced.

Innovations enhance genetic analysis of individual cells

Single cell genomics technology has given scientists the ability to individually read the genetic blueprints of cells, the most fundamental units of life.

Rheumatoid arthritis risk and noxious airborne agents

New research indicates that certain occupations may put workers at an elevated risk of developing rheumatoid arthritis. The findings suggest that work-related factors, such as noxious airborne agents, may contribute to the pathogenesis of rheumatoid arthritis. Environmental factors are thought to play a role in the development of rheumatoid arthritis by triggering autoimmune reactions in susceptible individuals.
