Who needs men? A female shark separated from her long-term mate has developed the ability to have babies on her own.

They’re back. Scimitar-horned oryx have been reintroduced to the wild after a two-decade absence and are flourishing in their old stomping grounds.
The desert antelopes were once widespread across northern Africa, but were hunted to extinction in their natural habitat in the 1990s.
Caspian tigers, some of the largest cats that ever lived — up to 10 feet long and weighing more than 300 pounds — met a grim end in the middle of the 20th century.
Until the mid-1960s when they were designated as extinct, they ranged from modern-day Turkey through much of Central Asia, including Iran and Iraq, to northwestern China. The reasons for their extermination are many
The first ever recorded video footage showing snow leopards and common leopards sharing the same habitat on the Tibetan plateau has caused concern among conservationists.
A chemical that is thought to be safe and is, therefore, widely used on crops—such as almonds, wine grapes and tree fruits—to boost the performance of pesticides, makes honey bee larvae significantly more susceptible to a deadly virus, according to researchers at Penn State and the U.S. Department of Agriculture.
The U.S. Fish and Wildlife Service has designated the rusty patched bumblebee an endangered species — the first such designation for a bumblebee and for a bee species in the continental U.S.
A new study has found that the same chemical that gives New Zealand manuka honey its unique antibacterial properties is present in Australian varieties as well.
Because bacteria doesn’t develop a resistance to this chemical, manuka honey could prove to be an invaluable tool in the global fight against antibiotic resistance.
For years, researchers have been tracking a particularly nasty family of superbugs called CREs, or carbapenem-resistant Enterobacteriaceae, which can thwart antibiotics in our last lines of defense. Researchers have watched in horror as clinical isolates gathered new molecular weaponry, spread through medical facilities across the globe, and started causing more and more life-threatening infections.
A new tool — a type of ultraviolet light called UVC — could aid hospitals in the ongoing battle to keep drug-resistant bacteria from lingering in patient rooms and causing new infections.
Duke researchers genetically modified Salmonella typhimurium to fight one of the most aggressive forms of brain cancer: Glioblastoma.
Lab tests in rats with extreme cases of glioblastoma showed an astonishing 20 percent survival rate, with the tumors going into remission over a period of 100 days.
MIT engineers have genetically reprogrammed a strain of yeast so that it converts sugars to fats much more efficiently, an advance that could make possible the renewable production of high-energy fuels such as diesel.
In a world struggling to kick its addiction to fossil fuels and feed its growing appetite for energy, there’s one technology in development that almost sounds too good to be true: nuclear fusion.
Fracking creates noise at levels high enough to harm the health of people living nearby, according to the first peer-reviewed study to analyze the potential public health impacts of ambient noise related to fracking.
A chronic inflammatory process that occurs in some, but not all, older people may trigger cardiovascular problems, a new Stanford study shows. Part of the solution might be found in a cup of coffee.

It’s January, the month of new diets and gym memberships. In the spirit of starting off a brand new year, there’s no reason not to eat healthier and move around more. But if your aim is just to lose pounds, you might be on the wrong track. In her new book, The Secret Life of Fat, biochemist Sylvia Tara reveals what many dieters have suspected for a long time: There’s more to losing weight than just eating less and exercise.
Flies with a history of eating a high sugar diet live shorter lives, even after their diet improves. This is because the unhealthy diet drives long-term reprogramming of gene expression, according to a team of researchers.
Put down the cake. Going on a permanent diet could make you live longer, if findings from monkeys hold true for people.
A long-running trial in macaques has found that calorie restriction makes them live about three years longer than normal, which would translate to about nine years in people.
