Pressures from grazers hastens ecosystem collapse from drought
Ecosystem collapse from extreme drought can be significantly hastened by pressures placed on drought-weakened vegetation by grazers and fungal pathogens, a new Duke-led study finds. The study's experimental evidence shows that the natural enemies of plants play a major role in lowering resilience to drought and preventing recovery afterward. The finding may be applicable to a wide range of ecosystems now threatened by climate-intensified drought, including marshes, mangroves, forests and grasslands.

Genetic opposites attract when chimpanzees choose a mate
Duke University researchers find that chimpanzees are more likely to reproduce with mates whose genetic makeup most differs from their own. Many animals avoid breeding with parents, siblings and other close relatives, researchers say. But chimps are unusual in that even among virtual strangers they can tell genetically similar mates from more distant ones. Chimps are able to distinguish degrees of genetic similarity among unfamiliar mates many steps removed from them in their family tree.

CWRU directly measures how perovskite solar films efficiently convert light to power
Researchers at Case Western Reserve University have directly shown that electrons generated when light strikes a well-oriented perovskite film are unrestricted by grain boundaries and travel long distances without deteriorating. Identification of this property, which is key to efficiently convert sunlight into electricity, could lead to more efficient solar panels.

WPI researcher wins NSF CAREER Award to study how bacteria survive in stressful conditions
With a five-year, $1.1 million CAREER Award from the National Science Foundation (NSF), Scarlett Shell at Worcester Polytechnic Institute (WPI) will study the molecular mechanisms that enable bacteria to endure starvation, lack of oxygen, and other hostile conditions, work that could have a broad impact in a number of fields and provide clues for treatments for infectious diseases, including multi-drug resistant strains of tuberculosis, a major global health threat

Why Lyme disease is common in the north, rare in the south
When it's hot and not too muggy, Lyme disease-bearing black-legged ticks avoid desiccation by hiding out where people don't tread. Scientists say that's why the illness is rare in the South, and may eventually fade out along the Mason-Dixon line.

New laser based on unusual physics phenomenon could improve telecommunications, computing
Researchers at the University of California San Diego have demonstrated the world's first laser based on an unconventional wave physics phenomenon called bound states in the continuum. The technology could revolutionize the development of surface lasers, making them more compact and energy-efficient for communications and computing applications. The new BIC lasers could also be developed as high-power lasers for industrial and defense applications.

Release of water shakes Pacific Plate at depth
A team of seismologists analyzing the data from 671 earthquakes that occurred between 30 and 280 miles beneath the Earth's surface in the Pacific Plate as it descended into the Tonga Trench were surprised to find a zone of intense earthquake activity in the downgoing slab. The pattern of the activity along the slab provided strong evidence that the earthquakes are sparked by the release of water at depth.

Tree-bark thickness indicates fire-resistance in a hotter future
A new study has found that trees worldwide develop thicker bark when they live in fire-prone areas. The findings suggest that bark thickness could help predict which forests and savannas will survive a warmer climate in which wildfires are expected to increase in frequency.

Killing time: Study sheds light on phages and precision cell destruction
Phage therapy, which exploits the ability of certain viruses to infect and replicate within bacteria, shows promise for treating antibiotic-resistant bacterial infections. But designing such therapies depends on understanding how phages work. Phages can kill the cell immediately, or become dormant and kill it later, with a high level of precision in kill time. Researchers from the University of Delaware and City University of New York shed light on the molecular process in PNAS.

Great Barrier Reef almost drowned; climate implications
The first comprehensive analysis of the Great Barrier Reef at a time of rapid sea-level rise during the beginning of the Last Interglacial found it almost died. The Ph.D. research shows the reef can be resilient but questions remain about cumulative impacts. The research also provides an accurate identification of the age of the fossil reef that grew before the modern Great Barrier Reef, some 129,000-121,000 years ago.

Foresters and researchers are using sound to look inside living trees. A new study in Applications in Plant Sciences presents methods for use of sonic tomography, which measures wood decay by sending sound waves through tree trunks. The new study describes optimum placement of the sensors to avoid aberrant tomography results for the non-model tree shapes that populate the tropics and details how to analyze the tomograms to quantify areas of decayed and damaged wood.
