The physics of wealth inequality
A Duke engineering professor has proposed an explanation for why the income disparity in America between the rich and poor continues to grow. According to the constructal law of physics, income inequality naturally grows along with the economy.

Asian dust providing key nutrients for California's giant sequoias
Dust from as far away as the Gobi Desert in Asia is providing more nutrients than previously thought for plants, including giant sequoias, in California's Sierra Nevada mountains, a team of scientists, including several from the University of California, Riverside, have found.

Study: Dust helps regulate Sierra Nevada ecosystems
A new study released March 28 in the journal Nature Communications indicates it's important to understand how dust helps vegetation thrive, especially in light of the changing climate and land-use intensification.

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.

How randomness helps cancer cells thrive
In a research effort that merged genetics, physics and information theory, a team at the Schools of Medicine and Engineering at Johns Hopkins University has added significantly to evidence that large regions of the human genome have built-in variability in reversible epigenetic modifications made to their DNA.

Renewable energy has robust future in much of Africa
Africa's energy demand is expected to triple by 2030. A new Berkeley study shows that the continent's energy needs can be met with renewable power from wind and solar in a way that reduces reliance on undependable hydroelectric power and imported fossil fuels, while at the same time saving money and providing jobs. Good sites exist for solar and wind farms even if one avoids remote or environmentally sensitive areas.

Mouse in the house tells tale of human settlement
Long before the advent of agriculture, hunter-gatherers began putting down roots in the Middle East, building more permanent homes and altering the ecological balance in ways that allowed the common house mouse to flourish, new research in the Proceedings of the National Academy of Sciences indicates. Findings suggest that the roots of animal domestication go back to human sedentism thousands of years prior to what has long been considered the dawn of agriculture.

Protein that regulates brain cell connections could be new target for treating Alzheimer's disease
In experiments with a protein called Ephexin5 that appears to be elevated in the brain cells of Alzheimer's disease patients and mouse models of the disease, Johns Hopkins researchers say removing it prevents animals from developing Alzheimer's characteristic memory losses. In a report on the studies, published online March 27 in The Journal of Clinical Investigation, the researchers say the findings could eventually advance development of drugs that target Ephexin5 to prevent or treat symptoms of the disorder.

Biodiversity loss shifts flowering phenology at same magnitude as global warming
Researchers have revealed that declining plant diversity -- from habitat loss, human use, and other environmental pressures -- causes plants to flower earlier, and that the effects of diversity loss on the timing of flowering are similar in magnitude to the effects of global warming. The finding could have a powerful influence on the way scientists study ecosystem changes and measure the effects of global warming.

Hydrophobic proteins on virus surfaces can help purify vaccines
Through experimental and computational tests, new research expands on the theory of virus surface hydrophobicity. By being slightly water-repellent, the outer layers of proteins in virus capsids affect how it interacts with cells and the environment. Understanding this more can improve vaccine production and virus detection.

Predatory lizard enters Brazil clandestinely
Anolis porcatus, a species native to Cuba, has been identified in several areas near the Port of Santos on the São Paulo coast, in Brazil. Its introduction into this area may threaten the survival of local lizard populations. A DNA study suggests these lizards could have come from Florida, where they're also exotic, rather than directly from Cuba.
