U.S. global share of research spending declines Posted: 01 Jan 2014 02:57 PM PST The United States' global share of biomedical research spending fell from 51 percent in 2007 to 45 percent in 2012, while Japan and China saw dramatic increases in research spending.

Alcohol, tobacco, drug use far higher in severely mentally ill Posted: 01 Jan 2014 01:19 PM PST Researchers have found that rates of smoking, drinking and drug use are significantly higher among those who have psychotic disorders than among those in the general population. The finding is of particular concern because individuals with severe mental illness are more likely to die younger than people without severe psychiatric disorders.

To grow or to defend: How plants decide Posted: 01 Jan 2014 10:07 AM PST Plant hormones called brassinosteroids help plants choose the best survival strategy depending on their stage of growth and environmental pressures.

Climatological software developed for massive use Posted: 01 Jan 2014 10:07 AM PST Understanding the weather behavior may not be as complicated as once thought, and would help to have more elements for decision making and prevention of natural disasters, as hurricanes or typhoons. Researchers make available this information available for anyone to know their community, state or country's weather activity for today and months ahead.

What patients need to know about revision surgery after hip or knee replacement Posted: 31 Dec 2013 10:27 AM PST Over the past two years, an expert in revision hip and knee replacement surgery has seen an increase in the number of people needing a second surgery. When a knee or hip implant wears out or another problem develops, people often need a second surgery in which the existing implant or components are taken out and replaced.

Sleep to protect your brain Posted: 31 Dec 2013 09:21 AM PST A new study shows that one night of sleep deprivation increases morning blood concentrations of NSE and S-100B in healthy young men. These molecules are typically found in the brain. Thus, their rise in blood after sleep loss may indicate that a lack of snoozing might be conducive to a loss of brain tissue.

Study finds medical students concerned about becoming desensitized to dying patients Posted: 31 Dec 2013 09:21 AM PST The imminent death of a patient is riddled with emotions for a patient and family as well as the medical team. A study based on the reflections of third-year medicine students is shedding light on the struggle physicians in training often face when trying to control their own emotions while not becoming desensitized to the needs of the dying patient and his or her family.

New species of marine algae identified Posted: 31 Dec 2013 06:43 AM PST The species that historically was quoted as the most abundant of coral algae that forms rodoliths at the Gulf of California in Mexico, is in reality a compound of five different species. This finding was made by a marine biologist, resulting in a change of paradigm in the study of the species known as Lithophyllum margaritae.

Subsituting bone with synthetic materials Posted: 31 Dec 2013 06:43 AM PST The Hydroxylapatite, medullar component of bone, when obtained synthetically and "giving" it some characteristics, could be used as a bone substitute.

Ancient traditions: Why we make new year resolutions Posted: 30 Dec 2013 04:10 PM PST As many of us start to think about our New Year's resolutions (or breaking them), we may not realize that the tradition of making promises on the first day of the year is a custom started by our Roman ancestors.

Medicaid beneficiaries use emergency services due to lack of alternatives Posted: 30 Dec 2013 02:03 PM PST A study shows that patients with Medicaid insurance seeking care in an emergency department may be driven by lack of alternatives instead of the severity of their illness.

High good, low bad cholesterol levels are healthy for brain, too Posted: 30 Dec 2013 02:03 PM PST High levels of "good" cholesterol and low levels of "bad" cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer's disease, in a pattern that mirrors the relationship between good and bad cholesterol in cardiovascular disease, researchers have found.

With few hard frosts, tropical mangroves push north Posted: 30 Dec 2013 02:03 PM PST Cold-sensitive mangrove forests doubled in area along N. Florida's Atlantic Coast as the frequency of killing frosts waned, according to a study based on 28 years of satellite data.

Molecular evolution of genetic sex-determination switch in honeybees Posted: 30 Dec 2013 02:01 PM PST It's taken nearly 200 years, but scientists in the United States and Europe have teased out how the molecular switch for sex gradually and adaptively evolved in the honeybee.

Conversations on sex lacking between doctors, teens Posted: 30 Dec 2013 02:01 PM PST Doctors are missing a prime opportunity to share information about sex with their teenage patients by failing to broach the subject during checkups, according to researchers.

Fetal alcohol syndrome heart defects may be caused by altered function, not structure Posted: 30 Dec 2013 10:51 AM PST Recent data shows that more than 500,000 women in the US report drinking during pregnancy, with about 20 percent of this population admitting to binge drinking. Even one episode of heavy drinking can lead to the collection of birth defects known as fetal alcohol syndrome.

Nicotine exploits COPI to foster addiction Posted: 30 Dec 2013 10:49 AM PST Study helps explain how nicotine exploits the body's cellular machinery to promote addiction. The findings could lead to new therapies to help people quit smoking.

Fructose does not impact emerging indicator for cardiovascular disease, research suggests Posted: 30 Dec 2013 07:15 AM PST Fructose, the sugar often blamed for the obesity epidemic, does not itself have any impact on an emerging marker for the risk of cardiovascular disease known as postprandial triglycerides, new research has found.

Slower-paced meal reduces hunger but affects calorie consumption differently Posted: 30 Dec 2013 07:14 AM PST According to a newly published study, eating at a slower rate reduces hunger, but affects calorie consumption differently in normal and overweight/obese people.

I’ll have what they’re having: Study finds social norms influence food choices Posted: 30 Dec 2013 07:14 AM PST Is obesity a socially transmitted disease? In order to find out, researchers in the United Kingdom conducted a systematic review of several experimental studies, each of which examined whether or not providing information about other peoples' eating habits influences food intake or choices.

Alcohol leaves its mark on youngsters' DNA Posted: 30 Dec 2013 07:14 AM PST A preliminary study indicates that weekend alcohol consumption may affect DNA.

Stress in the orchestra: mood plays a part Posted: 30 Dec 2013 07:14 AM PST Even professional orchestra musicians suffer from particular stress on the day of the concert and release more cortisol. For the first time, it has now been possible to demonstrate that, amongst others, the enzyme myeloperoxidase, which is regarded as a risk factor for cardiovascular disease, plays a part in the stress reaction in musicians. This effect is however dampened by an emotional factor: this is because a good mood reduces the stress-induced release of myeloperoxidase.

Use of media can save lives in bad storms Posted: 30 Dec 2013 07:14 AM PST The number and intensity of storms and other extreme weather events are on the increase all over the world. The latest study by the Medical University of Vienna in cooperation with the US Centers for Disease Control and Prevention (CDC) uses the example of one of the largest American series of tornados of all times to show that the risk of injury can be reduced significantly with the use of certain media.

Infection with common cold virus: scientists reveal new insights Posted: 30 Dec 2013 07:14 AM PST On average, each of us catches a cold two to three times a year. However, how the common cold virus actually infects us is only partly understood. Researchers have now provided new insights into this process.

Concussion history associated with risk of alzheimer's disease Posted: 26 Dec 2013 03:16 PM PST A new study suggests that a history of concussion involving at least a momentary loss of consciousness may be related to the buildup of Alzheimer's-associated plaques in the brain.

Gene therapy for human skin disease produces long-term benefits Posted: 26 Dec 2013 11:31 AM PST Researchers evaluated a patient with a genetic skin disorder known as epidermolysis bullosa nearly seven years after he had undergone a gene therapy procedure as part of a clinical trial. The study revealed that a small number of skin stem cells transplanted into the patient's legs were sufficient to restore normal skin function, without causing any adverse side effects.
