Racehorses are getting faster

Racehorses are getting faster

Despite a general consensus among scientists and in the racing industry that racehorse speed has plateaued, a new study from the University of Exeter has found that racehorses are getting quicker. Further research is required to determine whether the increased speeds have a genetic basis or are the result of improved training, jockey tactics or other environmental factors.

Men think they are math experts, therefore they are

Just because more men pursue careers in science and engineering does not mean they are actually better at math than women are. The difference is that men think they are much better at math than they really are. Women, on the other hand, tend to accurately estimate their arithmetic prowess, says Shane Bench of Washington State University in the U.S., leader of a study in Springer's journal Sex Roles.

Viagra does something important -- causing melanoma is not it

A rigorous analysis of more than 20,000 medical records concludes that erectile dysfunction drugs, such as Viagra, are not a cause of melanoma, an often deadly form of skin cancer, despite the higher risk for the disease among users of these drugs. A detailed report on the research findings is to be published in the Journal of the American Medical Association online June 23.

Adolescents aren't as certain about risks of marijuana as advocates are

Teenagers are very familiar with the risks of smoking cigarettes, but are much less sure whether marijuana or e-cigarettes are harmful, according to a new study by researchers at the Stanford University School of Medicine.

While adolescents get clear messages from their families, teachers, peers and the media about the harms of smoking cigarettes, they receive conflicting or sparse information about the harms of marijuana and e-cigarettes, the study showed.

The findings will be published online June 23 in the Journal of Adolescent Health.

How to find out if a cocktail of chemicals trigger cancer

A global taskforce of 174 scientists from leading research centres across 28 countries studied the link between mixtures of commonly encountered chemicals and the development of cancer. The study selected 85 chemicals not considered carcinogenic to humans and found 50 supported key cancer-related mechanisms at exposures found in the environment today.

One of the worst known invasive species discovered in the U.S.

The land planarian Platydemus manokwari, or New Guinea flatworm, is a highly invasive species, already reported in many territories in the Pacific area, and as well as in France. This is the only land planarian in the '100 worst invasive alien species' list and it has now been found in additional localities including islands in the Pacific area, Puerto Rico, the first record in the Caribbean, and the first report in mainland U.S., in Florida.

Hypertension drug isradipine may stop drug and alcohol addiction

Researchers at The University of Texas at Austin have successfully stopped cocaine and alcohol addiction in experiments using a drug already approved by the U.S. Food and Drug Administration (FDA) to treat high blood pressure. If the treatment is proven effective in humans, it would be the first of its kind -- one that could help prevent relapses by erasing the unconscious memories that underlie addiction.

The research is published this week in the journal Molecular Psychiatry.

Saying no to ACA Medicaid expansion costs states money

Twenty-one states have opted not to expand Medicaid under the Affordable Care Act (ACA), arguing that the expansion would be too expensive. But according to new research, the cost to hospitals from uncompensated care in those states roughly equals the cost of Medicaid expansion.

The study, “Hospitals as Insurers of Last Resort,” by economists at Northwestern University and Columbia University’s Mailman School of Public Health is released online today as a National Bureau of Economic Research working paper.
