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.
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.
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
Guest essay by Eric Worrall It would be wrong to think that the governments of the world are solely focussed on reducing CO2. Just in case the Paris conference fails to deliver, our selfless government scientists are spending your money, exploring a diverse range of strange mutant varieties of every day farm animals, to ensure…
Guest essay by Steve Goreham Unnoticed by most citizens, last week the United States Senate introduced the “Secret Science Reform Act of 2015.” The act is aimed at the Environmental Protection Agency’s practice of refusing to disclose data from scientific studies that support new pollution regulations. The act indirectly questions the EPA assertion that Americans…

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.
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.
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 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 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
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.
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
Researchers have found embryonic brown fat transplants reversed type 1 diabetes and restored glucose tolerance to normal in non-obese diabetic mice.
As Independence Day approaches, social media is lighting up with memes and quotes from the nation’s Founding Fathers. But did George Washington, Thomas Jefferson and Benjamin Franklin actually say these things for which they receive so much acclaim? A scholar can tell the truth about Ben.
According to new research, there may be a way to predict when Yellowstone volcano will erupt again.
There may be far fewer galaxies further out in the universe then might be expected, according to a new study.
A new earthquake swarm started off the coast of Iceland, the radius around a Japanese volcano has been evacuated, and the Fuego volcano in Guatemala has a plume more than three miles high! The post Eruption Update: Explosions at Hakone and Fuego, Swarm off Iceland appeared first on WIRED.
