Brine-Loving Microbes Reveal Secrets To Success In Chemically Extreme Environments:
Scientists have completed the first study of microbes that live within the plumbing of deep-sea mud volcanoes in the Gulf of Mexico, where conditions may resemble those in extraterrestrial environments and early Earth. The study, which was partially funded by the National Science Foundation (NSF), was conducted in an area where clusters of seafloor vents spew mud, oil, brine and gases that support food chains independently of the Sun.
Women May Be Sniffing Out Biologically-relevant Information From Underarm Sweat:
It may be wise to trust the female nose when it comes to body odor. According to new research from the Monell Center, it is more difficult to mask underarm odor when women are doing the smelling.
Use Of Native Southern African Plants In Veterinary Medicine:
When animals in southern Africa are sick, often the first place their caretakers look for help is from native plants. That's what makes understanding and conserving these plants so important, according to a group of Kansas State University researchers who are learning more about the uses of such plants in veterinary medicine.
Control, Treatment Of Bed Bugs Challenging:
A review of previously published articles indicates there is little evidence supporting an effective treatment of bites from bed bugs, that these insects do not appear to transmit disease, and control and eradication of bed bugs is challenging, according to a new article.
You Wear Me Out: Thinking Of Others Causes Lapses In Our Self-control:
Exerting self-control is exhausting. In fact, using self-control in one situation impairs our ability to use self-control in subsequent, even unrelated, situations. What about thinking of other people exerting self-control?
Melatonin May Be Served As Potential Anti-fibrotic Drug:
In China, the incidence of liver cirrhosis is still high. Liver cirrhosis results from fibrosis. If treated properly at fibrosis stage, cirrhosis can be prevented. However, no effective antifibrosis drugs are available at present. Several lines of evidences suggest that oxidative stress plays an important role in the etiopathogenesis of hepatic fibrosis. Melatonin can protect cells, tissues, and organs against oxidative damage induced by a variety of free-radical-generating agents and processes.
Sexual Behavior At Work Still A Problem, Study Shows:
Be careful of that raunchy joke that gets all the laughs. As funny as folks at work may find it, it's probably hurting morale. That's one conclusion of a groundbreaking new paper published in the Journal of Applied Psychology and co-authored by researchers from the University of Toronto's Rotman School of Management and the University of British Columbia's Sauder School of Management.
Is There A Seat Of Wisdom In The Brain?:
Researchers at the University of California, San Diego School of Medicine have compiled the first-ever review of the neurobiology of wisdom - once the sole province of religion and philosophy.
Focus On The Future: Long-term Goals Help Us Resist Unhealthy Urges:
Imagine a delicious pile of French fries next to a low-fat green salad. After resisting the fries, can you really be expected to go to the gym instead of watching TV? According to a new study, consumers who focus on long-term goals are more likely to resist unhealthy urges.
Large Number Of New Prions Discovered: Scientists Redefining What It Means To Be A Prion:
Special proteins known as prions, which are perhaps best known as the agents of mad cow and other neurodegenerative diseases, can also serve as an important source of beneficial variation in nature. Whitehead Institute researchers have quintupled the number of identifiable prion proteins in yeast and have further clarified the role prions play in the inheritance of both beneficial and detrimental traits.
Wild Chimpanzees Exchange Meat For Sex, Researchers Find:
Wild female chimpanzees copulate more frequently with males who share meat with them over long periods of time, according to a study led by researchers from the Max Planck Institute for Evolutionary Anthropology in Germany, published in the open-access, peer-reviewed journal PLoS ONE April 8.
Poison -- It's What's For Dinner: Hunt Narrows For Genes That Let Packrats Eat Creosote:
As the U.S. Southwest grew warmer from 18,700 to 10,000 years ago, juniper trees vanished from what is now the Mojave Desert, robbing packrats of their favorite food. Now, University of Utah biologists have narrowed the hunt for detoxification genes that let the rodents eat toxic creosote bushes that replaced juniper.
DNA Used To Study Migration Of Threatened Whale Sharks:
Whale sharks -- giants of the fish world that strike terror only among tiny creatures like the plankton and krill they eat -- are imperiled by over-fishing of the species in parts of its ocean range.
