Painkiller Abuse Tied to Skyrocketing Heroin Use in US

People who are addicted to opioids are 40 times more likely than others to abuse heroin, making the abuse of prescription opioid painkillers the strongest risk factor for heroin use, according to a new report. "Heroin use is increasing at an alarming rate in many parts of society, driven by both the prescription opioid epidemic and cheaper, more available heroin," said Dr. Tom Frieden, director of

When Did Women Start to Outlive Men?

It's well known that women live longer than men do, but this wasn't always the case: A new study finds that differences between men and women's life expectancies began to emerge in the late 1800s. They found that over this time period, death rates decreased among both men and women. For example, among people born before 1840, death rates were about the same for men and women of a given age.

Low Testosterone May Raise Depression Risk

Men with lower levels of testosterone may be at increased risk of depression, a new study finds. Researchers found that more than half of the men in the study who had lower levels of testosterone had a diagnosis of depression, or showed symptoms of the condition, while a quarter of participants were taking medication for the disease. The vast majority of male participants in the new George Washing

Scientists convinced European heat waves boosted by climate change

By Laurie Goering LONDON (Thomson Reuters Foundation) - As Germany and Spain sweated and London sweltered through its hottest July day on record this week, scientists said it is "virtually certain" that climate change is increasing the likelihood of such heat waves in Europe. In real-time data analysis released on Friday, a team of international climate scientists from universities, meteorological

Seabirds Smell Their Way Home

By assessing bird flight patterns, a team of scientists has found evidence supporting the idea that seabirds navigate using smell. This is the "first direct evidence that seabirds use odor maps to navigate over vast expanses of visually featureless oceans to locate preferred grounds, and then to return home and pinpoint their breeding colony," said Andrew Reynolds, lead author of the new study d

Federal report: Polar bears in peril due to global warming

ANCHORAGE, Alaska (AP) — Polar bears are at risk of dying off if humans don't reverse the trend of global warming, a blunt U.S. government report filed Thursday said.

Plague Evolution: How a Mild Stomach Bug Became a Worldwide Killer

The Black Death — the dreaded plague that killed millions of people during the Middle Ages — only reached pandemic status after the bacteria that cause it acquired two pivotal mutations, a new study finds. With the first of those mutations, ancient strains of plague bacteria (Yersinia pestis) gained the ability to cause pneumonic plague — a respiratory form of the disease that spreads easily whe

Woolly Mammoth Clones Closer Than Ever, Thanks to Genome Sequencing

Scientists are one step closer to bringing a woolly mammoth back to life. A new analysis of the woolly mammoth genome has revealed several adaptations that allowed the furry beasts to thrive in the subzero temperatures of the last ice age, including a metabolism that allowed them to pack on insulating fat, smaller ears that lost less heat and a reduced sensitivity to cold. The findings could ena

How Not to Get Stung by a Portuguese Man-of-War

Like cast members on a distasteful reality show, Portuguese man-of-war "jellyfish" are descending upon the Jersey Shore in increasing numbers. Last week, one of these venomous creatures (which are related to jellyfish) washed up in Harvey Cedars, a town on Long Beach Island, New Jersey. Man-of-war fish have stinging cells that are still active and capable of stinging even after the creature is dea
