Researchers control soft robots using magnetic fields
Engineering researchers have made a fundamental advance in controlling so-called soft robots, using magnetic fields to remotely manipulate microparticle chains embedded in soft robotic devices. The researchers have already created several devices that make use of the new technique.

Solving the mystery of the Arctic's green ice
In 2011, researchers observed something that should be impossible -- a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. So, how was this bloom possible? Using mathematical modeling, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences found that thinning Arctic sea ice may be responsible for these blooms and more blooms in the future, potentially causing significant disruption in the Arctic food chain.

Social bees have kept their gut microbes for 80 million years
Bacteria living in the guts of social bees have been passed down from generation to generation for 80 million years, according to a new study. The finding adds to the case that social creatures, like bees and humans, not only transfer bacteria between one another in their own lifetime -- they have a distinctive relationship with bacteria over time, in some cases even evolving on parallel tracks as species.

Viruses in the oceanic basement
A team of scientists from the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology (SOEST) showed for the first time that many novel viruses are present in the fluids circulating deep in the rocky crust of the seafloor known as the ocean basement. Their recently published study also provides evidence that the viruses are actively infecting the many unusual microorganisms that live in the basement.

Seabird bones, fossils reveal broad food-web shift in North Pacific
For thousands of years, the Hawaiian petrel has soared over the Pacific Ocean, feeding on fish and squid. Now, using evidence preserved in the birds' bones, scientists at the Smithsonian's National Museum of Natural History and Michigan State University have discovered that the now endangered seabird has experienced a significant shift in food resources most likely during the past 100 years--a disruption that may be due to industrial fishing practices.

Fighting world hunger: Robotics aid in the study of corn and drought tolerance
Developing 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.

Igniting a solar flare in the corona with lower-atmosphere kindling
Recent images captured by NJIT's 1.6-meter New Solar Telescope at Big Bear Solar Observatory (BBSO) have revealed the emergence of small-scale magnetic fields in the lower reaches of the corona the researchers say may be linked to the onset of a main flare.

Highway to health: WSU findings point way to more nutritious crops
Washington State University researchers have had the closest look yet at the inner workings of a plant's circulatory system. Their findings show how nutrients get from the leaves, where they are produced through photosynthesis, to 'sinks' that can include the fruits and seeds we eat and the branches we process for biofuels.

Toward glow-in-the-dark tumors: New fluorescent probe could light up cancer

Hair spacing keeps honeybees clean during pollination
A honeybee can carry up to 30 percent of its body weight in pollen because of the strategic spacing of its nearly three million hairs. The gap between each eye hair is approximately the same size as a grain of dandelion pollen, which is typically collected by bees. This keeps the pollen suspended above the eye and allows the forelegs to comb through and collect the particles.

Satellites reveal bird habitat loss in California
Reduced seasonal flooding of wetlands and farm fields in California's Sacramento Valley threatens a key stopover site for migratory shorebirds, a Duke-led study shows. Landsat satellite images reveal that flooded habitat is most limited during peak spring migration when the birds urgently need resting and feeding sites. Near the peak of migration, an area of seasonally flooded land twice the size of Washington, D.C. has been lost since 1983.

Psychologists enlist machine learning to help diagnose depression
Cognitive neuroscientists from The University of Texas at Austin are using the Stampede supercomputer to provide accurate predictions of risk for those with depression and anxiety. They have been able to classify individuals with major depressive disorder with roughly 75 percent accuracy using a machine learning approach. Stampede 2 --which will come online later in 2017 -- will provide the increased computer processing required to incorporate more data and achieve even greater accuracy.

Mobile gold fingers
Drugs containing gold have been used for centuries to treat conditions like rheumatoid arthritis. In addition, they might be effective against cancer and HIV. One mechanism by which they work could occur because gold ions force the zinc ions out of zinc fingers -- looped, nucleic acid binding protein domains. American researchers have characterized such 'gold fingers' using ion mobility mass spectrometry. As reported in the journal Angewandte Chemie, they identified the exact gold binding sites.

The electric sands of Titan
Experiments suggest the particles that cover the surface of Saturn's moon, Titan, are 'electrically charged.' When the wind blows hard enough, Titan's non-silicate granules get kicked up and start to hop in a motion. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth -- they become resistant to further motion.
