Physics: It's happening inside your body right now
Using a model blood vessel system built on a polymer microchip, researchers have shown that the relative softness of white blood cells determines whether they remain in a dormant state along vessel walls or enter blood circulation to fight infection.

Search technique helps researchers find DNA sequences in minutes rather than days
Database searches for DNA sequences that can take biologists and medical researchers days can now be completed in a matter of minutes, thanks to a new search method developed by computer scientists at Carnegie Mellon University.

Early human ancestor didn't have the jaws of a nutcracker, study finds
Research published in 2012 garnered international attention by suggesting that a possible early human ancestor had lived on a diverse woodland diet including hard foods mixed in with tree bark, fruit, leaves and other plant products. But new research by an international team of researchers now shows that Australopithecus sediba didn't have the jaw and tooth structure necessary to exist on a steady diet of hard foods.

Scientists say window to reduce carbon emissions is small
At the rate humans are emitting carbon into the atmosphere, the Earth may suffer irreparable damage that could last tens of thousands of years, according to a new analysis. Sea level rise is a critical issue. With seven degrees (Celsius) warming at the high-end scenario of temperature increase, the sea level rise is estimated at 50 meters, over a period of several centuries to millennia.

Central Appalachia flatter due to mountaintop mining
Forty years of mountaintop coal mining have made parts of Central Appalachia 40 percent flatter than they were before excavation, researchers say. This study, which compares pre- and post-mining topographic data in southern West Virginia, is the first to examine the large-scale impact of mountaintop mining on landscape topography and how the changes influence water quality.

Lithium battery catalyst found to harm key soil microorganism
The material at the heart of the lithium ion batteries that power electric vehicles, laptop computers and smartphones has been shown to impair a key soil bacterium. The study by researchers at the University of Wisconsin-Madison and the University of Minnesota is an early signal that the growing use of the new nanoscale materials used in the rechargeable batteries that power portable electronics and electric and hybrid vehicles may have untold environmental consequences.

'On-ramping' paves the way for women scientists, engineers to return to academia
Pursuing scientific or engineering careers in industry, government or private research after getting a Ph.D. used to be considered a one-way ticket out of academia. But new University of Washington research finds numerous benefits -- to students, researchers and academic institutions looking to diversify their faculty -- in making that return trip easier.

Scientists map movement of Greenland Ice during past 9,000 years

How gut inflammation sparks colon cancer
Duke biomedical engineers have shown how colon cancer development is intricately linked to a specific microRNA that dictates how cells divide. The new study points to a link between chronic gut inflammation and an increased risk of colon cancer. That link could not only serve as an early warning signal of colon cancer, but potentially be harnessed to counteract advanced forms of the disease, the second-largest cause of cancer death in the US.

Smithsonian scientists discover butterfly-like fossil insect in the deep Mesozoic
Large butterfly-like insects known as Kalligrammatid lacewings, which fluttered through Eurasian fern- and cycad-filled woodland during the Mesozoic Era, have been extinct for more than 120 million years. But with new fossil analyses, scientists at the Smithsonian's National Museum of Natural History have discovered that these ancient lacewings were surprisingly similar to modern butterflies, which did not appear on Earth for another 50 million years.

Same switches program taste and smell in fruit flies
A Duke study helps explain how fruit flies get their keen sense of smell. Researchers have identified a set of genetic control switches that interact early in a fly's development to generate dozens of types of specialized nerve cells for smell. The findings could reveal how the nervous systems of other animals -- including humans, whose brains have billions of neurons -- produce a dazzling array of cell types from just a few genes.

IUPUI chemist receives $1.1 million for research, training of future minority researchers
Supported by an NSF CAREER award, Lisa M. Jones of IUPUI is developing a novel approach to study of cell membrane proteins in their native cellular environment -- work fundamental to gaining a better understanding of protein misfolding, which has been linked to life-limiting human diseases including cystic fibrosis. Her work provides state-of-the-art research training for undergraduate students from historically black colleges and universities as well as both undergraduate and graduate students from IUPUI.

Phosphine as a superconductor? Sure, but the story may be complicated
Phosphine, one of the newest materials to be named a superconductor, was reported in 2015 to exhibit superconductivity when squeezed under high pressure in a diamond vice. Now, a different group of researchers is providing insight into what may have happened to the phosphine as it underwent this intense compression.

Galactic center's gamma rays unlikely to originate from dark matter, evidence shows
Studies by two independent groups from the US and the Netherlands have found that gamma ray signals from the inner galaxy come from a new source rather than from the collision of dark matter particles. The new source is likely to be rapidly rotating pulsars, rather than the as-yet undetected invisible dark matter particles thought to make up 85 percent of the mass in the Universe.

Geologists from Brown University may have finally explained what triggers certain earthquakes that occur deep beneath the Earth's surface in subduction zones, regions where one tectonic plate slides beneath another. The researchers have shown strong evidence that water squeezed out of a mineral called lawsonite could trigger these mysterious quakes.
