Extreme temperatures threaten desert songbirds with death by dehydration
According to NASA, 2016 was the hottest year on historical record. Globally, the increase amounted to nearly 1.8 degrees Fahrenheit. And while that might not sound like much of an increase, it could mean the difference between life and death for some bird populations.

Climate change increases lethal dehydration risk in desert songbirds
As the Earth warms from climate change, the risk of lethal dehydration and mass die-offs of songbirds during heat waves will increase in many areas of the world, according to a study by the University of Nevada, Reno, the University of New Mexico and the University of Massachusetts-Amherst published today in the scientific journal Proceedings of the National Academy of Sciences.

Measuring entropy: Scanning-tunneling microscope gives glimpse of the mysterious property
New research shows that the scanning-tunneling microscope (STM), which is used to study changes in the shape of a single molecule at the atomic scale, impacts the ability of that molecule to make these changes. The research is published in the current issue of Nature Communications.

Desert songbirds may face expanding threat of lethal dehydration
A new study of songbird dehydration and survival risk during heat waves in the desert Southwest suggests that some birds are at risk of lethal dehydration and mass die-offs when water is scarce, and the risk is expected to increase as climate change advances. Using physiological data, hourly temperature maps and modeling, Alex Gerson at UMass Amherst and others investigated how rates of evaporative water loss varied in five bird species with varied body mass.

Researchers discover a new link to fight billion-dollar threat to soybean production
Invisible to the naked eye, cyst nematodes are a major threat to agriculture, causing billions of dollars in global crop losses every year. A group of plant scientists, led by University of Missouri researchers, recently found one of the mechanisms cyst nematodes use to invade and drain life-sustaining nutrients from soybean plants. Understanding the molecular basis of interactions between plants and nematodes could lead to the development of new strategies to control these major agricultural pests and help feed a growing global population.

Chemical engineers boost bacteria's productivity
MIT chemical engineers have designed a novel genetic switch that allows them to dramatically boost bacteria cells' production of useful chemicals by shutting competing metabolic pathways in the cells. The researchers showed that they could significantly enhance the yield of glucaric acid, a chemical precursor to products such as nylons and detergents.

Researchers develop first reliable technique to track web users across browsers
A team of researchers led by Yinzhi Cao, assistant professor computer science and engineering at Lehigh University has developed the first cross-browser fingerprinting technique to use machine-level features to identify users. The work is described in a paper called: '(Cross-) Browser Fingerprinting via OS and Hardware Level Features.' Cao and his colleagues are scheduled to present their findings at the Internet Society's Network and Distributed System Security (NDSS) Symposium next week, Feb. 26-March 1 in San Diego, Calif.

Mismatched eyes help squid survive ocean's twilight zone
Biologists have gathered the first behavioral evidence that cockeyed squids' mismatched eyes evolved to spot two different sources of light available in the deep sea. Their one large eye is adapted for gazing upwards, searching for shadows of fellow sea creatures against fading sunlight, while their small eye is adapted for gazing downwards, scanning deeper water for bioluminescent flashes, according to researchers at Duke University and the Monterey Bay Aquarium Research Institute (MBARI).

50+ year-old protein volume paradox resolved
Research published this week in Nature Communications makes it possible to predict how volume for a given protein will change between the folded and unfolded state. Computations accurately predict how a protein will react to increased pressure, shed light on the inner-workings of life in the ocean depths, and may also offer insights into alien life.

Protecting bulk power systems from hackers
Most of us take turning the lights on for granted. In reality, the energy we draw from the electrical grid to brighten homes, freeze food and watch TV is part of a complicated and widespread system. Understanding that system's vulnerabilities and reliability is a crucial step towards improving its security.

Cold plates and hot melts
The movements of Earth's tectonic plates shape the face of our planet. The sinking of one plate beneath another causes volcanism and earthquakes. As part of the International Ocean Discovery Program, an international science team was able to drill and investigate the origin of a subduction zone for the first time in 2014. The team is now publishing its data in the international scientific journal Earth and Planetary Science Letters.

Wave of the future: Terahertz chips a new way of seeing through matter
Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, have long required elaborate and expensive equipment to use. Now, researchers at Princeton University have drastically shrunk much of that equipment: moving from a tabletop setup with lasers and mirrors to a pair of microchips small enough to fit on a fingertip.

Silver ion-coated medical devices could fight MRSA while creating new bone
The rise of MRSA infections is limiting the treatment options for physicians and surgeons. Now, an international team of researchers, led by Elizabeth Loboa, dean of the University of Missouri College of Engineering, has used silver ion-coated scaffolds, or biomaterials that are created to hold stem cells, which slow the spread of or kill MRSA while regenerating new bone. Scientists feel that the biodegradable and biocompatible scaffolds could be the first step in the fight against MRSA in patients.
