Basil Orbits Earth

When she blasted off onboard the space shuttle last week, teacher-turned-astronaut Barbara Morgan carried millions of basil seeds to the ISS. Soon she'll return millions more "space seeds" for students on Earth to study.

Cosmic Cockroaches

A tough, pesky molecule possibly key to the origins of life on Earth has been spotted in deep space surviving the ferocious blastwave of a supernova explosion.

Hurtling Toward Mars

Earth and Mars are rapidly converging. Relative speed: 22,000 mph. Contrary to rumor, Mars is not about to swell to the size of a full Moon, but there is something eerie and Martian to look for in the night sky next week.

Ability To 'Tell The Difference' Declines As Infants Age

A new article suggests that infants fine-tune their visual and auditory systems to stimuli during the first year of life, essentially "weeding out" unnecessary discriminatory abilities.

Importantly, if...

He says that the most solid evidence of recognizing clinical severity in febrile children in primary care is a full assessment by an experienced clinician.

Male Deer Are Born To Live Fast, Die Young

Natural selection favors reproduction rather than survival. Males of ungulate species subjected to intense male-male competition in order to mate have shorter lives than females. Males are born already with smaller molars relative to their body size, which means the teeth won't last as long. These findings provide insight into how natural and sexual selection design our bodies.

Secondhand Smoke Is A Health Threat To Pets

It has been in the news for years about how secondhand smoke is a health threat to nonsmokers. Secondhand smoke is attributed with killing thousands of adult nonsmokers annually. If smoking is that harmful to human beings, it would make sense that secondhand smoke would have an adverse effect on pets that live in the homes of smokers. Researchers note that, "one reason cats are so susceptible to...

Sports Medicine Physicians Brace For The Injuries Of Football Season

Football fever is upon the nation once again. The soaring of the pigskin signals the start of the "busy" season for cheerleaders, marching bands, and inevitably, sports medicine physicians. Prevention is the primary goal of everyone involved in the sport, but when large, highly charged males engage in bodily contact, injuries are inevitable. Knee and ankle sprains are the most common injuries...
