Molecular 'kiss of death' flags pathogens
Disease-causing microorganisms hide in protective bubbles on the cell surface called vacuoles, making it difficult for the immune system to recognize and destroy them without causing harm to the rest of the cell. A Duke team has found that the body marks pathogen-containing vacuoles for destruction with a molecule called ubiquitin, commonly known as the 'kiss of death.' The finding could lead to new therapeutics that boost the immune system's response to pathogens.

UMD, partners receive $4.5 million to study cosmic flashes
A Caltech-led project that includes UMD astronomers has been selected to receive $4.5 million over five years by the National Science Foundation. The project aims to improve our understanding of cosmic transients by formally establishing a network of telescopes at longitudes throughout North America, Asia and Europe to extend the hours of nighttime observing. At UMD, undergraduates in two new courses will analyze data collected by the telescopes to obtain scientifically useful results.

Study shows insect diversity decreases in gardens with non-native plants

How sign language users learn intonation
A spoken language is more than just words and sounds. Speakers use changes in pitch and rhythm, known as prosody, to provide emphasis, show emotion, and otherwise add meaning to what they say. In a study appearing today in the September 2015 issue of Language, three linguists look at intonation (a key part of prosody) in ASL and find that native ASL signers learn intonation in much the same way that users of spoken languages do.

New tech automatically 'tunes' powered prosthetics while walking
When amputees receive powered prosthetic legs, the power of the prosthetic limbs needs to be tuned by a prosthetics expert so that a patient can move normally -- but the prosthetic often needs repeated re-tuning. Biomedical engineering researchers have developed software that allows powered prosthetics to tune themselves automatically, making the devices more functionally useful and lowering the costs associated with powered prosthetic use.

NYC risks future flooding during hurricanes
Whether or not a coastal city floods during a hurricane depends on the storm, tide and sea level, and now a team of climate scientists show that the risk of New York City flooding has increased dramatically during the industrial era as a result of human-caused climate change.

Flood risk on rise for New York City and New Jersey coast, study finds
For the first time, climate researchers compared both sea-level rise rates and storm surge heights in prehistoric and modern eras and found that the combined increases of each have raised the likelihood of a devastating 500-year flood occurring as often as every 25 years.

Ocean circulation rethink solves climate conundrum
Researchers from the University of Exeter believe they have solved one of the biggest puzzles in climate science. The new study, published in Nature Geoscience, explains the synchrony observed during glacial periods when low temperatures in the Southern Ocean correspond with low levels of atmospheric carbon dioxide.

Chip-based technology enables reliable direct detection of Ebola virus
A team led by researchers at UC Santa Cruz has developed chip-based technology for reliable detection of Ebola virus and other viral pathogens. The system uses direct optical detection of viral molecules and can be integrated into a simple, portable instrument for use in field situations where rapid, accurate detection of Ebola infections is needed to control outbreaks.

Extreme Pacific sea level events to double in future
Many tropical Pacific island nations are struggling to adapt to gradual sea level rise stemming from warming oceans and melting ice caps. Now they may also see much more frequent extreme sea level swings. The culprit is a projected behavioral change of the El Niņo phenomenon and its characteristic Pacific wind response, according to recent computer modeling experiments and tide-gauge analysis by scientists at the University of Hawai'i at Mānoa and CSIRO in Australia.

Bumblebees' adaptation to climate change could lead to rise in declining bee population
Rising temperatures in alpine habitats worldwide have resulted in declines in flowering among indigenous plants and contributed to dramatic declines in populations of several bumblebee species prevalent in those regions. Now, researchers at the University of Missouri in a study published in Science, have found that two bumblebee species have responded to this decline in flowering due to warming temperatures by evolving shorter tongues. Results suggest that some bumblebee species may be able to adapt to environmental challenges.

Study shows new forests cannot take in as much carbon as predicted
As carbon emissions continue to rise, scientists project forests will grow faster and larger, due to an increase in atmospheric carbon dioxide, which fuels photosynthesis. But a new study by researchers at the University of Illinois at Urbana-Champaign and the University of Bristol in the United Kingdom finds that these projections are overestimated.

Botanist to study responses of trees and shrubs to extreme drought in California
California is in its fourth year of drought. As a result, mass mortality of trees and shrubs is happening more quickly than researchers can quantify. Rapid changes in vegetation cover are already leading to loss of biodiversity, opportunities for invasive species, and novel ecosystems with entirely new plant communities. Botanist Louis Santiago at UC Riverside, has now received a grant from the National Science Foundation to study how trees and shrubs respond to extreme drought.
