Does radiation from X-rays and CT scans really cause cancer?

In recent years, there has been widespread media coverage of studies purporting to show that radiation from X-rays, CT scans and other medical imaging causes cancer. But such studies have serious flaws, including their reliance on an unproven statistical model, according to a recent article.

Location isn't everything but timing is for certain spawning fish

Each year, hundreds to thousands of fish aggregate at highly predictable times and locations to spawn, producing larvae that will spend at least a month in the plankton before settling to reef habitat. The larvae of some species of reef fish appear to survive better depending on the timing of when they were spawned, according to new research.

HUDs are duds: Augmented reality on windshields is a danger, finds study

Augmented-reality head-up displays (AR-HUDs) that present digital images on windshields to alert drivers to everything from possible collisions to smart phone activity, are meant to make driving safer. But University of Toronto researchers say they are a threat to safety. read more

Carbon capture and storage safety investigated

A significant step has been made for potential Carbon Capture and Storage (CCS) deployment, with the publication of the results from the world's first experiment into the realistic simulation of potential environmental impact of a submarine CO2 leakage.

Bizarre mating habits of flatworms

Failing to find a mating partner is a dent to the reproductive prospects of any animal, but in the flatworm species Macrostomum hystrix it might involve a real headache. Zoologists have discovered the extraordinary lengths to which this animal is willing to go in order to reproduce -- including apparently injecting sperm directly into their own heads.

Successful heart transplant after using experimental artificial heart

A 44-year-old woman has received a successful heart transplant, thanks to an experimental Total Artificial Heart designed for smaller patients. The patient is the first person in California to receive the smaller Total Artificial Heart, and the first patient in the world with the device to be bridged to a successful heart transplant.

Indoor tanning rates drop among US adults

Indoor tanning rates dropped among adults from 5.5 percent in 2010 to 4.2 percent in 2013, although an estimated 7.8 million women and 1.9 million men still engage in the practice, which has been linked to increased cancer risk, according to the results of a new study.

Boys more likely to have antipsychotics prescribed, regardless of age

Boys are more likely than girls to receive a prescription for antipsychotic medication regardless of age, researchers have found. Approximately 1.5 percent of boys ages 10-18 received an antipsychotic prescription in 2010, although the percentage falls by nearly half after age 19. Show More Summary

Newly discovered 48-million-year-old lizard walked on water in Wyoming

A newly discovered, 48-million-year-old fossil, known as a 'Jesus lizard' for its ability to walk on water, may provide insight into how climate change may affect tropical species.

Dagger-like canines of saber-toothed cats took years to grow

The fearsome teeth of the saber-toothed cat Smilodon fatalis fully emerged at a later age than those of modern big cats, but grew at a rate about double that of their living relatives. The findings, for the first time, provide specific ages for developmental dental events in Smilodon. Show More Summary

Brown fat transplant reversed type 1 diabetes without insulin in non-obese diabetic mice

Researchers have found embryonic brown fat transplants reversed type 1 diabetes and restored glucose tolerance to normal in non-obese diabetic mice.

Misquotes and memes: Did Ben Franklin really say that?
