Twin discoveries, 'eerie' effect may lead to manufacturing advances
The discovery of a previously unknown type of metal deformation -- sinuous flow -- and a method to suppress it could lead to more efficient machining and other manufacturing advances by reducing the force and energy required to process metals.

Some vaccines support evolution of more-virulent viruses
Scientific experiments with the herpesvirus such as the one that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of severe illness. The research has important implications for food-chain security and food-chain economics, as well as for other diseases that affect humans and agricultural animals.

Parasitic flatworms flout global biodiversity patterns
The odds of being attacked and castrated by a variety of parasitic flatworms increases for marine horn snails the farther they are found from the tropics. A Smithsonian-led research team discovered this exception to an otherwise globally observed pattern -- usually biodiversity is greatest in the tropics and decreases toward the poles.

Inbreeding not to blame for Colorado's bighorn sheep population decline
The health of Colorado's bighorn sheep population remains as precarious as the steep alpine terrain the animals inhabit, but a new study led by researchers at the University of Colorado Boulder has found that inbreeding -- a common hypothesis for a recent decline -- likely isn't to blame.

Study finds abrupt climate change may have rocked the cradle of civilization
New research reveals that some of the earliest civilizations in the Middle East and the Fertile Crescent may have been affected by abrupt climate change. These findings show that while socio-economic factors were traditionally considered to shape ancient human societies in this region, the influence of abrupt climate change should not be underestimated.

Scripps researchers map out trajectory of April 2015 earthquake in Nepal
Researchers from Scripps Institution of Oceanography at UC San Diego have accurately mapped out the movement of the devastating 7.8-magnitude Nepal earthquake that killed over 9,000 and injured over 23,000 people. Scientists have determined that the earthquake was a rupture consisting of three different stages. The study could help a rapidly growing region understand its future seismic risks.

The discovery of jets of material ejected from still-forming brown dwarfs provides the first direct evidence that these enigmatic objects form in the same way as their more-massive siblings, stars, rather than like planets.

ASBMB wins National Science Foundation grant to expand mentorship program
The National Science Foundation awarded the American Society for Biochemistry and Molecular Biology a grant of half a million dollars to support a comprehensive mentoring program for postdoctoral fellows and early-career faculty members. The program focuses on grantsmanship skills and career-development strategies. It also promotes diversity in the scientific workforce by supporting underrepresented minority postdoctoral scientists and new assistant professors in their efforts to secure research funding.

Penn researchers discover new chiral property of silicon, with photonic applications
By encoding information in photons via their spin, 'photonic' computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin of electrons, rather than just their quantity, could make 'spintronic' computers with similar advantages. University of Pennsylvania engineers and physicists have now discovered a property of silicon that combines aspects of all of these desirable qualities.

UT Dallas nanotechnology research leads to super-elastic conducting fibers
A research team based at the University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to over 14 times their initial length and whose electrical conductivity increases 200-fold when stretched. In a study published in the July 24 issue of the journal Science, the scientists describe how they constructed the fibers by wrapping electrically conductive sheets of carbon nanotubes to form a jelly-roll-like sheath around a long rubber core.

Smarter window materials can control light and energy
Chemical engineering professor Delia Milliron and her team have engineered two new advancements in electrochromic materials -- a highly selective cool mode and a warm mode -- not thought possible several years ago. The researchers are one step closer to delivering smart windows with a new level of energy efficiency.

Predicting the shape of river deltas
Now researchers from MIT and the Woods Hole Oceanographic Institution have devised a simple way to predict a river delta's shape, given two competing factors: its river's force in depositing sediment into the ocean, and ocean waves' strength in pushing that sediment back along the coast. Depending on the balance of the two, the coastline of a river delta may take on a smooth 'cuspate' shape, or a more pointed 'crenulated' outline, resembling a bird's foot.

Researchers quantify nature's role in human well-being
The benefits people reap from nature -- or the harm they can suffer from natural disasters -- can seem as obvious as an earthquake. Yet putting numbers to changes in those ecosystem services and how human well-being is affected has fallen short, until now. A team of researchers from Michigan State University are advancing new modeling technology to quantify human dependence on nature, human well-being, and relationships between the two.

Stress 'sweet spot' differs for mellow vs. hyper dogs
People aren't the only ones who perform better on tests or athletic events when they are just a little bit nervous -- dogs do too. But in dogs as in people, the right amount of stress depends on disposition. A new study by researchers at Duke University finds that a little extra stress and stimulation makes hyper dogs crack under pressure but gives mellow dogs an edge.
