New info on an elusive green cicada

For nearly 80 years, the North American cicada Okanagana viridis has received little attention in scientific literature, but a new article in the Annals of the Entomological Society of America provides the first notes on the song and ecology of this elusive species, and updates its known range.

Novel vaccine reduces shedding of genital herpes virus

Sexually transmitted infection researchers potentially have reached a milestone in vaccine treatment for genital herpes, according to a report to be presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy in Denver, Colo., today, Sept. 12.

Older drinkers may experience fewer hangovers due to less intense drinking

While hangovers may be a source of humor, their effects can be debilitating, costly, and even dangerous. A new study of hangovers across the lifespan has found that the tendency to experience hangovers decreases as age increases.Study authors speculate that older adults who binge drink do so to a lesser intensity than younger adults.

Poxue Huayu and Tianjing Busui Decoction for cerebral hemorrhage

Poxue Huayu and Tianjing Busui Decoction can markedly elevate the expression of brain-derived neurotrophic factor, tyrosine kinase B and vascular endothelial growth factor in the brain, thereby providing a new scientific therapeutic method for protecting neurons after cerebral hemorrhage.

Probing methane's secrets: From diamonds to Neptune

Hydrocarbons from the Earth make up the oil and gas that heat our homes and fuel our cars. The study of the various phases of molecules formed from carbon and hydrogen under high pressures and temperatures, like those found in the Earth's interior, helps scientists understand the chemical processes occurring deep within planets, including Earth. New research hones in on the hydrocarbon methane...

Pulsating dust cloud dynamics modelled

The birth of stars is an event that eludes intuitive understanding. It is the collapse of dense molecular clouds under their own weight that offers the best sites of star formation. Now, a paper in EPJ D has proposed a new model for investigating molecular cloud fluctuations at sites of star formation and thus are able to study their pulsational dynamics.

Research shows denser seagrass beds hold more baby blue crabs

A new study in Chesapeake Bay by researchers at William & Mary's Virginia Institute of Marine Science shows that it's not just the presence of a seagrass bed that matters to young crabs, but also its quality -- with denser beds holding exponentially more crabs per square meter than more open beds where plants are separated by small patches of mud or sand.

Research treats the fungus among us with nontoxic medicinal compound

A Kansas State University research team has found a breakthrough herbal medicine treatment for a common human fungal pathogen that lives in almost 80 percent of people. The team discovered a medicinal herb called Gymnema slyvestre is both nontoxic and blocks the virulence properties of a common fungus called Candida albicans.

Researchers hit virtual heads to make safer games

Two nearly identical softballs, both approved for league play, can have dramatically different effects when smacked into a player's head.Those are the findings from a study conducted by Professor Lloyd Smith in the School of Mechanical and Materials Engineering and project engineer Derek Nevins that they will present at the Asia Pacific Congress on Sports Technology later this month in Hong Kong....

Revised Medicaid policy could reduce unintended pregnancies, save millions in health costs

A revised Medicaid sterilization policy that removes logistical barriers, including a mandatory 30-day waiting period, could potentially honor women's reproductive decisions, reduce the number of unintended pregnancies and save $215 million in public health costs each year, according to researchers at the University of Pittsburgh School of Medicine. Their findings support growing evidence for the...

Scientific societies face 'modern challenges'

An article published in the Sept. issue of BioScience highlights the challenges facing biological societies and offers insights for scientific societies to respond and adapt to the changing dynamics of 21st century science.

Scripps Florida scientists pinpoint proteins vital to long-term memory

Scientists from the Florida campus of the Scripps Research Institute have found a group of proteins essential to the formation of long-term memories. The proteins send signals from the outside to the inside of a cell, inducing a cellular response crucial for many aspects of embryonic development, including stem cell differentiation, as well as for normal functioning of the adult brain.

Sewage treatment removes widely used home and garden insecticides from wastewater

Even though sewage treatment plants are not designed to remove tiny amounts of pesticides, they do an excellent job of dealing with the most widely used family of home and garden insecticides, scientists reported here today. Their study on pyrethroid insecticides -- used in more than 3,500 products -- was part of the 246th National Meeting & Exposition of the American Chemical Society, the world's...

Sober drinking knowledge often fails 'in the moment' of intoxication

Approximately one-third of all fatal crashes each year in the US involve an alcohol-impaired driver. New research compares individuals' perceived dangerousness of driving after drinking while intoxicated with those perceptions while sober.Results show that sober knowledge does not necessarily translate into responsible judgment while intoxicated.

Stem cells are wired for cooperation, down to the DNA

We often think of human cells as tiny computers that perform assigned tasks, where disease is a result of a malfunction. But in the current issue of Science, researchers at The Mount Sinai Medical Center offer a radical view of health -- seeing it more as a cooperative state among cells, while they see disease as result of cells at war that fight with each other for domination.

Study explores complex physical oceanography in East China Sea

Just days before a team of researchers set out to conduct fieldwork in the East China Sea, Typhoon Morakot -- one of the most destructive storms ever to hit Taiwan -- made landfall on the island, causing widespread damage and drastically altering the flow of water along the nearby continental shelf. Their research may offer a new understanding of how chaotic and powerful currents form in the East...
