The research also revealed that being bullied at school about their sports achievements left young female athletes with lasting psychological and social problems they carried into adulthood.
In a self-professed sports-mad country, why is this happening?-->
By Marsha Lewis, Inside Science – Each year, about 32 billion bottles of wine are bought and sold around the world. Each bottle contains about two and a half pounds of grapes, and to transform those grapes into a beverage with the perfect aroma, color, and taste, winemakers carefully monitor the complex chemistry bubbling away in wineries’ fermentation tanks.
“I would say the trickiest part of making wine is getting the flavors right,” said Linda Bisson, a yeast geneticist at the University of California, Davis.-->
A new study has found that long-term stimulant abuse had more significant effects on brain volume in women compared with men.
The researchers sought to determine how the brains of people previously dependent on stimulants were different from the brains of healthy people.
The researchers analyzed structural brain magnetic resonance imaging exams in 127 men and women, including 59 people (28 women and 31 men) who were previously dependent on cocaine, amphetamines and/or methamphetamine for an average of 15.7 years, and 68 people (28 women and 40 men) who were similar in age and were not previously dependent on those drugs.
Healing times for skin ulcers and bedsores can be reduced by a third with the use of low-intensity ultrasound - ultrasound transmits a vibration through the skin and wakes up cells in wounds helping to stimulate and accelerate the healing process.
More than 200,000 patients in the UK suffer with chronic wounds every year at a cost of over £3.1 billion to the NHS, according to background information in the article. The ultrasound treatment, which also reduces the chance of wounds getting infected, is particularly effective when treating diabetics and the elderly.
Surgeries related to overuse elbow injuries, i.e. Tommy John Surgery, are more common among youth athletes than previously believed, according to research presented last week at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in Orlando.
"Our results showed that 15-19 year-olds accounted for 56.7 percent of the Ulnar Collateral Ligament Reconstruction (UCLR) or Tommy John surgeries performed in the U.S. between 2007-2011. This is a significant increase over time with an average increase of 9.12 percent per year," said lead author, Brandon Erickson, MD of Rush University Medical Center in Chicago, Illinois.
By Charles Choi, Inside Science -- Bloodcurdling screams in horror movies often send tingles down people's spines, even though they know such shrieks are fake. Now scientists have discovered the key ingredient of screams that activates the brain's fear circuitry. Inventors may have unknowingly copied this hair-raising acoustic feature into alarms found in cars and houses.-->
New research has confirmed plutonium's magnetism, which scientists have long theorized but have never been able to experimentally observe.
Plutonium was first produced in 1940 and its unstable nucleus allows it to undergo fission, making it useful for nuclear fuels as well as for nuclear weapons. Much less known, however, is that the electronic cloud surrounding the plutonium nucleus is equally unstable and makes plutonium the most electronically complex element in the periodic table, with intriguingly intricate properties for a simple elemental metal.
A lot of attention has been given to city dwellers and the health risks of sitting in front of a computer screen, but almost 50 of the world spends 75 percent of their time on their feet.
Prolonged standing is associated with short-term adverse health issues, including reports of fatigue, leg cramps, and backaches, which can affect job performance and cause significant discomfort. A new study published in Human Factors suggests that, over time, this type of sustained muscle fatigue can result in serious health consequences.
Researchers have developed an inhalable vaccine that protects primates against Ebola.
Previous studies with primates suggest that aerosols of most biothreat agents, which are particles dispersed in the air, are infectious. Recent studies show that contact with the Ebola virus through the mucus membranes that line the respiratory tract results in infection, suggesting that airway linings may be important portals of entry for the virus. Aerosolized delivery has never before been tested for an Ebola vaccine or any other viral hemorrhagic fever vaccine.
On April 20, 2010, BP's Deepwater Horizon (DWH) drilling rig experienced a failure resulting in the discharge of gas and light sweet crude oil from a depth of approximately 5,000 feet.
Discharge continued for 87 days until July 15, 2010, five years ago this week, when the well was capped and the leak was contained.
From trilobites to tyrannosaurs, most fossils are of creatures with hard shells or bones. These materials don’t easily biodegrade and sediment has time to build up around them and turn them into a record of the creature that is still with us millions of years after it has died. Soft-bodied organisms like worms, on the other hand, decay rapidly and their fossil record is decidedly patchy.
In exceptional circumstances, however, their remains are preserved and sometimes in the most unusual places. With the right detective skills, palaeontologists can use such discoveries to open up whole new windows on the history of life on Earth. A recent discovery found in 50-million-year-old rocks from Antarctica has yielded a particularly incredible example: fossilised worm sperm.-->
Collectively, diseases of the airways such as emphysema, bronchitis, asthma, and cystic fibrosis are the second leading cause of death worldwide.
More than 35 million Americans alone suffer from chronic respiratory disease. Weizmann Institute of Science researchers have now proposed a new direction that could, in the future, lead to the development of a method for alleviating some of the suffering of these patients. The study’s findings show how it might be possible to use embryonic stem cells to repair damaged lung tissue.
