Barrier screens reduce damage from brown marmorated stink bug

LEXINGTON, KY - The brown marmorated stink bug, first identified in the United States in Pennsylvania in the mid-1990s, has spread to at least 42 states and two Canadian provinces. The invasive pest has been able to rapidly extend its range because of its ability to overwinter in heated structures.

Protecting grapes from pests by boosting their natural immunity

From protecting our most valuable works of art to enabling smartphone displays, glass has become one of our most important materials. Making it even more versatile is the next challenge. Developing new glass compositions is largely a time-consuming, trial-and-error exercise. But now scientists have developed a way to decode the glass "genome" and design different compositions of the material without making and melting every possibility. Their report appears in ACS' journal Chemistry of Materials.

Researchers provide new insights on coral bleaching

Reef-building corals have a symbiotic relationship with Symbiodinium algae, and environmental stressors that cause algae to be expelled from reefs can give rise to the phenomenon known as coral bleaching.

New research indicates that singlet oxygen, which is a reactive oxygen species, may play an important role in triggering the release of algae from coral tissue when coral bleaching occurs.

"The findings may help research efforts aimed at protecting reefs, which help support many marine species," said Dr. Imre Vass, senior author of the New Phytologist study.

Low doses of common cancer drug may promote cancer spread

New research indicates that paclitaxel, which is the most commonly used chemotherapy for breast cancer, suppresses tumors when given at a certain dosage, but at low doses, it actually promotes cancer spread to the liver.

The findings suggest that lowering the dose of paclitaxel to reduce toxic side-effects is not a safe strategy.

New targeted drug effectively dissolves blood clots, has fewer side effects

Critical conditions associated with the blockage of blood vessels are one of the primary health concerns worldwide. The main objective of emergency assistance in such conditions is to effectively implement thrombolysis, i. e. to quickly dissolve the clot. To this end, scientists from ITMO University in cooperation with Mariinsky Hospital in Saint Petersburg have developed a magnetically controlled drug that can be condensed on a blood clot by means of a magnetic field.

Airplanes make clouds brighter

Clouds may have a net warming or cooling effect on climate, depending on their thickness and altitude. Artificially formed clouds called contrails form due to aircraft effluent. In a cloudless sky, contrails are thought to have minimal effect on climate. But what happens when the sky is already cloudy? In a new study published in the journal Nature Communications, scientists at ACES and colleagues from the UK show that contrails that are formed within existing high clouds increase the reflectivity of these clouds, i.e. their ability to reflect light.

Wild boars and wart hogs may have an internal compass

New research suggests for the first time that wild boars and wart hogs have an internal magnetic compass that helps them orient themselves as they forage for food and inhabit new areas.

Cancer, violence among top health concerns for Chicago's South Siders

Residents on the South Side say cancer, violence prevention and sexually transmitted infections are among their top health concerns, according to the latest comprehensive assessment conducted by the University of Chicago Medicine.

Lizard tail adaptations may reflect predators' color vision capabilities

Juveniles of numerous lizard species have a vividly blue-colored tail that likely serves to deflect predator attacks toward the detachable tail rather than the lizard's body. Now researchers have found that certain differences in blue and UV light reflectance in lizard tails are likely adaptations to predators with different color vision capabilities.

Study addresses safety concerns for older adults with diagnosed and undiagnosed dementia

Dementia currently affects some 5 million people in the U.S., and that number is expected to triple by 2050. Having dementia affects the way you think, act, and make decisions.

In a study published in the Journal of the American Geriatrics Society, researchers examined how often older adults who have diagnosed and undiagnosed dementia engage in potentially unsafe activities.

Some older adults live well, despite advancing years and the burdens of chronic diseases

You might believe that older adults who deal with extensive chronic illnesses or serious diseases would be more likely to be frail and to have a poorer quality of life than healthier older adults. That may be true for some elders--but not for all.

The new system that uses sound to alleviate water shortage

Montreal, June 22, 2016 -- The world is approaching a water crisis. According to the International Water Management Institute, 33 per cent of the world's population will experience water scarcity by 2025.

One main cause is leaks. Twenty to 30 per cent of treated water is lost in systems because of this simple and fixable problem.

Teachers optimistic about Common Core writing standards, but not tests

EAST LANSING, Mich. -- Teachers believe the Common Core standards in their states can improve how they teach writing, but they also find plenty of shortcomings with the standards - and with the associated state writing tests in particular.

New study helps determine which older adults might need help taking medications

As age increases, older adults can develop problems taking their medications. But until now, few studies have examined the traits that might cause elders to need help with their medications, or how widespread a problem this might be.

Scientists reveal sub-Saharan Africa's legacy of past migrations over last 4,000 years

Researchers from the University of Oxford have revealed that the genetic ancestries of many of sub-Saharan Africa's populations are the result of historical DNA mixing events, known as admixture, within the last 4,000 years.

Their study, to be published in the journal eLife, uncovers signatures of these admixture events through a large analysis of DNA from populations across the continent. The discovery provides a foundation for the recent genetic history of the continent, which could aid future studies of non-communicable and infectious diseases, such as malaria.
