Tiny muscles help bats fine-tune flight, stiffen wing skin
Bats appear to use a network of hair-thin muscles in their wing skin to control the stiffness and shape of their wings as they fly, according to a new study. The finding provides new insight about the aerodynamic fine-tuning of membrane wings, both natural and man-made.

A new concept to improve power production performance of wind turbines in a wind farm
A modern wind farm usually consists of multiple wind turbines arranged in an organized pattern or array. Wake interferences among wind turbines have been found to affect the performance of the wind turbines significantly. In 2014(5) issue of Science China: Physics, Mechanics & Astronomy, the effects of relative rotation direction of wind turbines on the wake interferences among tandem turbines were studied for improved power production performance of wind turbines in a wind farm.

Supernova caught in the act by palomar transient factory
The intermediate Palomar Transient Factory operated by Caltech scans the sky constantly in search of dramatic astrophysical events. In 2013, it caught a star, probably a Wolf-Rayet star, in the act of exploding.

Male and female sex cell determination requires lifelong maintenance and protection
The way in which the sex of an organism is determined may require lifelong maintenance, finds new research from the University of Minnesota. According to the study published today in the journal Developmental Cell, sex-specific transcription factors perform lifelong work to maintain sexual determination and protect against reprogramming of cells from one sex to the other.

Delegating the dirty work is a key to evolution

JILA study finds crowding has big effects on biomolecules
Crowding has notoriously negative effects at large size scales, blamed for everything from human disease and depression to community resource shortages. But relatively little is known about the influence of crowding at the cellular level. A new JILA study shows that a crowded environment has dramatic effects on individual biomolecules.

Screening for autism: There's an app for that
Researchers have developed software to help interpret videotaped behaviors of infants during autism screening tests. The program's accuracy proved equal to autism experts and better than both non-expert medical clinicians and students in training.

Web services companies, such as Facebook, Google and Microsoft, all make promises about how they will use personal information they gather. A team from Carnegie Mellon University and Microsoft Research has automated the method to ensure that large codebases are operating in compliance with those promises and has deployed a prototype automated system on the data analytics pipeline of Bing, Microsoft's search engine.

Rhythmic bursts of electrical activity from cells in ear teach brain how to hear
A precise rhythm of electrical impulses transmitted from cells in the inner ear coaches the brain how to hear, according to a new study led by researchers at the University of Pittsburgh School of Medicine. The ear generates spontaneous electrical activity to trigger a response in the brain before hearing actually begins, said senior investigator Karl Kandler, Ph.D., professor of otolaryngology and neurobiology at Pitt School of Medicine.

Shrub growth decreases as winter temperatures fluctuate up
Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs because the growing season would be longer. But shrubs achieve less yearly growth when cold winter temperatures are interrupted by temperatures warm enough to trigger growth.

With climate changing, southern plants outperform northern
Can plants and animals evolve to keep pace with climate change? A new study shows that for at least one widely-studied plant, the European climate is changing fast enough that strains from Southern Europe already grow better in the north than established local varieties.

Scientists study biomechanics behind amazing ant strength
A recent study into the biomechanics of the necks of ants -- a common insect that can amazingly lift objects many times heavier than its own body -- might unlock one of nature's little mysteries and, quite possibly, open the door to advancements in robotic engineering. Ohio State University engineers combined laboratory testing and computational modeling conducted at the Ohio Supercomputer Center to determine the relationship between mechanical function, structural design and material properties of ant necks.

Professors' super waterproof surfaces cause water to bounce like a ball
Engineers like Julie Crockett and Dan Maynes have spent decades studying super-hydrophobic surfaces because of the plethora of real-life applications. And while some of this research has resulted in commercial products that keep shoes dry or prevent oil from building up on bolts, the duo of BYU professors are uncovering characteristics aimed at large-scale solutions for society.

Humpback whale subspecies revealed by genetic study
A new genetic study has revealed that populations of humpback whales in the oceans of the North Pacific, North Atlantic and Southern Hemisphere are much more distinct from each other than previously thought, and should be recognized as separate subspecies. Understanding how connected these populations are has important implications for the recovery of these charismatic animals that were once devastated by hunting.

Having and raising offspring is costly phase of life for baboon moms
Observations made in Kenya as part of one of the world's longest-running studies of a wild primate show how having offspring influences the health of female baboons. These observations highlight that females are mostly injured on days when they are likely to conceive. In addition, injuries heal the slowest when they are suckling their young. The study is published in Springer's journal Behavioral Ecology and Sociobiology.
