Researchers at the University of Georgia have a message for Southern tree farmers worried about unexplainable pine tree deaths: Don't panic.
It is well known that muscles need resistance (gravity) to maintain optimal health, and when they do not have this resistance, they deteriorate. A new report published in the July 2015 issue of The FASEB Journal, however, suggests that this might not be true for all muscles, offering hope that there may be ways to preserve muscle mass and strength for individuals in low-resistance environments, whether it be the microgravity of space, extended periods in a hospital bed, or a 9-5 job behind a desk.
Across the entire world, women have a greater life expectancy than men. But why? Was this always the case?
According to a new study led by University of Southern California Leonard Davis School of Gerontology researchers, significant differences in life expectancies between the sexes first emerged as recently as the turn of the 20th century. As infectious disease prevention, improved diets and other positive health behaviors were adopted by people born during the 1800s and early 1900s, death rates plummeted, but women began reaping the longevity benefits at a much faster rate.
Researchers have discovered that a human antibody specific to dengue virus serotype 2, called 2D22, protects mice from a lethal form of the virus -- and they suggest that the site where 2D22 binds to the virus could represent a potential vaccine target.
The mosquito-borne virus, which infects nearly 400 million people around the world each year, has four distinct serotypes, or variations, and there is currently no protective vaccine available.
Flu vaccines can be a shot in the dark - they must they be given yearly and there's no guarantee the strains against which they protect will be the ones circulating once the season arrives.
New research suggests it may be possible to harness a previously unknown mechanism within the immune system to create more effective and efficient vaccines against this ever-mutating virus.
Being busy with acts of kindness can help people who suffer from social anxiety to mingle more easily, according to a new stud.
Sufferers from social anxiety are more than just a little shy. Dealings with others might make them feel so threatened or anxious that they often actively avoid socializing. Although this protects them from angst and possible embarrassment, they lose out on the support and intimacy gained from having relationships with others. They have fewer friends, feel insecure when interacting with others, and often do not experience emotional intimacy even in close relationships.
Two migraine surgery techniques targeting a specific "trigger site" are both highly effective in reducing the frequency and severity of migraine headaches, according to a randomized trial.
Patients with temporal-type migraine derive similar and significant improvement from techniques that relieve pressure on (decompression) or remove a portion of (neurectomy) the nerve responsible for triggering their headaches, reports Bahman Guyuron, MD, Emeritus professor of plastic surgery at Case School of Medicine, Cleveland, and colleagues.
Trees that can tolerate soil pollution are also better at defending themselves against pests and pathogens.
While studying the presence of genetic information (RNA) from fungi and bacteria in the trees, the researchers found evidence of a very large amount of RNA from a very common plant pest called the two-spotted spidermite.
99% of spidermite RNA was in higher abundance in trees without contamination, suggesting that the polluted plant's defense mechanisms, used to protect itself against chemical contamination, improves its resistance to a biological invader.
Another Fourth of July is here, the time for backyard barbecues, picnics, cookouts, parades, swimming and fireworks.
One of those Independence Day pastimes, however, stands apart: fireworks. They’re a somewhat controversial topic in the US and are covered by a patchwork of different laws.-->
When we smell a rose, we might take a deep breath to get the the sweet but subtle floral scent - and in a public bathroom we would wisely do just the opposte. Yet people with autism spectrum disorder (ASD) don't make this natural adjustment like other people do, autistic children go right on sniffing in the same way, no matter how pleasant or awful the scent.
Researchers writing in a new paper suggest that non-verbal tests related to smell might serve as useful early indicators of ASD. Earlier evidence had indicated that people with autism have impairments in "internal action models," the brain templates we rely on to seamlessly coordinate our senses and actions. It wasn't clear if this impairment would show up in a test of the sniff response, however.
In a step that they say overturns traditional assumptions and practice, researchers at the Tata Institute of Fundamental Research, Mumbai and Institute for Plasma Research, Gandhi Nagar have fashioned bacteria to emit intense, hard x-ray radiation.
When one thinks of hard x-rays and bacteria it is usually that the bacteria are at the receiving end of the x-ray source - being imaged, irradiated for some modification or simply assessed for radiation damage. One hardly thinks of using bacteria as a source of x-rays, far from turning them into the brightest among such sources.
This timeless text speaks to all - adult, child, reader and player. The adaptability of Lewis Carroll’s language, the openness of its story world and the malleable nature of Alice’s character all beckon us to return to Wonderland in its many different guises.-->
A woman coping with the burden of familial breast cancer can't help but wonder if her young daughter will suffer the same fate. Has she inherited the same disease-causing mutation? Is it better to start working on worst-case scenarios now or wait? What will each do?
Observations of Greenland's Helheim Glacier link the process through which chunks of ice at the edge of a glacier break away, which has been hard to study, to seismically detectable events known as glacial earthquakes, which have been increasing in number in recent years.
Because seismic signals from these events can be detected by instruments located all over the globe, it should be possible to use glacial earthquakes as proxies for the glacier edge breaking process, known as calving.
The Phase IIb pivotal study of P2B001 for the treatment of early stage Parkinson's Disease has been announced as a success.
P2B001 is a combination of low dose pramipexole and low dose rasagiline administered as a proprietary sustained release formulation. The study, titled A Phase IIb, Twelve Week, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study, To Determine the Safety, Tolerability and Efficacy of Two Doses of Once Daily P2B001 in Subjects with Early Parkinson's Disease, showed that it met primary and secondary clinical endpoints for both dose combinations. Specifically, the results showed:
