Tue, 28 Mar 2017 14:56:17 EDTWhile orbiting the Moon in 1971, the crew of Apollo 15 photographed a strange geological feature—a bumpy, D-shaped depression about two miles long and a mile wide—that has fascinated planetary scientists ever since. Some have suggested that the feature, known as Ina, is evidence of a volcanic eruption Moon within the past 100 million years—a billion years or so after most volcanic activity on the Moon is thought to have ceased.

Tue, 28 Mar 2017 14:54:19 EDTDeveloping drought tolerant corn that makes efficient use of available water will be vital to sustain the estimated 9 billion global population by 2050. In March 2014, the National Science Foundation (NSF) awarded the University of Missouri a $20 million grant as part of a multi-institutional consortium to study how corn maintains root growth during drought conditions. Using funding from the NSF, Mizzou engineers on a multidisciplinary team have developed a robotic system that is changing the way scientists study crops and plant composition.
Tue, 28 Mar 2017 14:53:25 EDTAlmost every calorie that we eat at one time went through the veins of a plant. If a plant's circulatory system could be rejiggered to make more nutrients available - through bigger seeds or sweeter tomatoes - the world's farmers could feed more people.

Tue, 28 Mar 2017 14:46:34 EDTHigh-intensity focused ultrasound (HIFU) is a breakthrough therapeutic technique used to treat tumors. The principle of this noninvasive, targeted treatment is much like that of focusing sunlight through a lens, using an ultrasonic transducer like a convex lens to concentrate ultrasound into a small focal region. In an article appearing this week in the Journal of Applied Physics, a multi-institutional team of researchers in China have now designed a semi-enclosed, spherical cavity transducer for potential application in HIFU that can generate a steady, standing-wave field with a subwavelength-scale focal region and extremely high ultrasound intensity.
Tue, 28 Mar 2017 14:46:02 EDTWhen the Earth is dark, human activity sparkles across the globe. As seen from space, night-time lights tell a story about how we live, correlating to everything from electricity consumption and CO2 emissions, to gross domestic product, population and poverty.

Tue, 28 Mar 2017 12:47:17 EDTPicture bacteria and viruses locked in an arms race. For many bacteria, one line of defense against viral infection is a sophisticated RNA-guided "immune system" called CRISPR-Cas. At the center of this system is a surveillance complex that recognizes viral DNA and triggers its destruction. However, viruses can strike back and disable this surveillance complex using "anti-CRISPR" proteins, though no one has figured out exactly how these anti-CRISPRs work—until now.
Tue, 28 Mar 2017 12:46:05 EDTAs certain species decline in number, the geographic areas they inhabit also shrink. Still, even with less space to occupy, these decreasing populations manage to remain locally abundant.

Tue, 28 Mar 2017 12:00:01 EDTA bacterial species that hunts other bacteria has attracted great interest as a potential living antibiotic, but exactly how this predator tracks down its prey has not been clear. A study published March 28 in Biophysical Journal sheds light on this question, revealing that the bacterial predator Bdellovibrio bacteriovorus (BV) homes in on its target by taking advantage of fluid forces generated by its own swimming movements and those of its prey. These hydrodynamic flow fields bring the bacteria in close proximity, giving BV a greater chance of successful attack.

Tue, 28 Mar 2017 11:56:02 EDTThe U.S. Environmental Protection Agency (EPA) carries out experiments in which volunteer participants agree to be intentionally exposed by inhalation to specific pollutants at restricted concentrations over short periods to obtain important information about the effects of outdoor air pollution on human health. A new report by the National Academies of Sciences, Engineering, and Medicine finds these studies are warranted and recommends that they continue under two conditions: when they provide additional knowledge that informs policy decisions and regulation of pollutants that cannot be obtained by other means, and when it is reasonably predictable that the risks for study participants will not exceed biomarker or physiologic responses that are of short duration and reversible.
