It seems like a strange place to call a wildlife park: Nearly 30 years after the most catastrophic nuclear incident in global history, Chernobyl’s exclusion zone has turned into a paradise for animals of all species and sizes. A variety of raptors, deer, big cats, foxes, bears and birds have moved into the region, taking advantage of a vast habitat with almost no humans. That habitat, though, is contaminated with radioactive materials, and scientists still hotly debate the potential costs of radiation exposure to the animals of Chernobyl, some of whom have become famous.

Researchers have seen an explosion of wildlife at the site in recent years, with camera traps providing an opportunity to look deep into the world of the region’s animals without disturbing them. Stunning photography shows animals like wolves and bears roaming freely in the exclusion zone, unconcerned about the potential for human visitors. Perhaps most astonishingly, a population of Przeswalski’s horses, an endangered species critical to the biological and evolutionary history of modern equids, is booming in the region—which isn’t exactly what one might expect, given the radioactive contamination.

Mother’s Day is a good time to reflect on the amazing lengths some moms go to to ensure the well being of their children. One such “supermom” is Debby Elnatan, a former Israeli stay-at-home mom who became a press sensation when she invented the “Upsee”, a harness that allowed her young disabled son, and other handicapped children around the world, to walk in tandem with their parents.

When we first wrote about the Firefly Upsee harness a little over a year ago, the device was just gaining worldwide attention. A year later, NoCamels speaks to the inventor of the Upsee to hear about the future of the international company she is now heading.

The UN's International Agency for Research on Cancer (IARC) said Friday (20 March) that three pesticides, including the popular weed killer Roundup, were "probably" carcinogenic and two others, which have already been outlawed or restricted, were "possibly" so.

IARC classified the herbicide glyphosate – the active ingredient in Roundup – and the insecticides malathion and diazinon as "probably carcinogenic" on the basis of "limited evidence" of cancer among humans.

High social status has its privileges ­­when it comes to aging – even in wild animals.

In a first-of-its-kind study involving a wild species, Michigan State University researchers have shown that social and ecological factors affect animal health. The results, published in the current issue of Biology Letters, focused on spotted hyenas in Kenya.

“High-ranking members in hyena clans reproduce more, they live longer and appear to be in better overall health,” said Nora Lewin, MSU doctoral student of zoology and co-lead author. “If you want to see the hierarchy of spotted hyenas, throw down some fresh meat near them. It’s quickly apparent who’s dominant and who’s not.”

But Lewin wondered if long-accepted biological markers would support what she was seeing in the field. Thanks to working with fellow lead author Kay Holekamp, MSU zoologist, and her long-running hyena experiment, Lewin had access to more than 25 years of data and was able to spend a summer afield in Kenya, observing hyenas’ social structure firsthand.

A fetus exposed to tobacco smoke may be at increased risk for diabetes in adulthood, a new study of adult daughters finds. The results will be presented in a poster Saturday, March 7, at ENDO 2015, the annual meeting of the Endocrine Society in San Diego. 

Women whose parents smoked during pregnancy had increased risk of diabetes mellitus independent of known risk factors, adding to the evidence that prenatal environmental chemical exposures can contribute to adult diabetes mellitus. 

Changes in drinking water quality in the 21st Century are coming from a myriad of circumstances, and not all are for the best. Top contenders for why water-drinking quality might become suspect to the average consumer include California's drought conditions, the technology of fracking, and the nationwide aging infrastructure of rusty, degrading pipes.

Citing these and other relatively recent scenarios, Andrea Dietrich, professor of civil and environmental engineering at Virginia Tech, and her colleague Gary A. Burlingame of the Philadelphia Water Department, are calling for a critical review and rethinking of the U.S. Environmental Protection Agency's (EPA) secondary standards for maintaining consumers' confidence in tap water as well as in its sensory quality.

When it comes to skin infections, a healthy and robust immune response may depend greatly upon what lies beneath. In a new paper published in the January 2, 2015 issue of Science, researchers at the University of California, San Diego School of Medicine report the surprising discovery that fat cells below the skin help protect us from bacteria. 

Richard Gallo, MD, PhD, professor and chief of dermatology at UC San Diego School of Medicine, and colleagues have uncovered a previously unknown role for dermal fat cells, known as adipocytes: They produce antimicrobial peptides that help fend off invading bacteria and other pathogens. 

The drugs we release into the environment are likely to have a significant impact on plant growth, finds a new study led by the University of Exeter Medical School and Plymouth University. By assessing the impacts of a range of non-steroidal anti-inflammatory drugs, the research has shown that the growth of edible crops can be affected by these chemicals – even at the very low concentrations found in the environment.

Earlier this year whales won a historic victory when the International Court of Justice ruled that Japan’s scientific whaling program in the Antarctic was illegal and ordered it be ended, but Japan is back at it with plans to continue under a new proposal. Despite a worldwide moratorium on commercial whaling that was put in place in 1986, Japan has continued with annual whale hunts that it claims are being conducted to collect scientific data. Whale advocates, however, have long argued that Japan has been abusing a loophole in the moratorium that allows for lethal scientific research whaling. Fortunately for whales, the court agreed, ruling that Japan’s program breached international law, had no justifications for the quotas it was setting and that it had failed to consider non-lethal alternatives under it’s JARPA II research program.

In 2009, China's estimated 300 million smokers consumed a staggering 2.3 trillion cigarettes: more than the number smoked in the next four top tobacco-consuming countries—Indonesia, Japan, Russia, and the United States—combined. The health toll is enormous as well: Tobacco causes roughly 1 million deaths in China each year, including 100,000 fatalities blamed on secondhand smoke, according to the World Health Organization (WHO). If tobacco use is not curtailed, WHO warns, China’s death toll could rise to 3 million each year by 2050.

The nation’s capital, Beijing, is taking that chilling message to heart. On 28 November, the Beijing Municipal Government adopted a ban on smoking in all indoor public places—"with no loopholes and no exemptions," crowed Bernhard Schwartländer, the WHO representative in China, in a press release. The new law will take effect on 1 June 2015.
