Yellowstone National Park is expected to kill nearly 900 of its bison this winter, marking the largest cull since 2008. Although laws state that culls are needed to manage growing populations and protect Montana's livestock for infectious diseases bison may be carrying, conservationists argue this large-scale slaughter is unnecessary and brutal -- they have filed a lawsuit claiming that the public has a right to witness this year's controversial cull.
Biologists have genetically engineered mosquitoes to reduce populations of mosquitoes carrying Zika virus, which is linked to a birth defect known as microencephaly. The hope is this will help stop the virus from spreading to the Americas and reduce the number of people impacted.
Social mammals, including humans and mongooses, may compete in groups to produce larger offspring. A new study found that this, in addition to males' vying to pass along their genes by winning antler-fighting contests and the like, may be part of the evolutionary effort to increase the survival rate of one's own offspring.
After nearly being wiped out in Britain, conservationists report the native European Polecat is making a strong comeback across the continent.
American pikas prefer to live in cold, mountainous habitats. As climate change brings warmer temperatures, researchers believe the key to their survival will be remaining in close-knit patches.
Micro-CT scans helped scientists identify the first female of a Madagascan chameleon species known as Calumma vatosoa. Before now, the species was only known by a single male found in 2001.
A monarch butterfly's wing patterns may ultimately provide clues as to where it was born. This could help researchers learn more about the iconic creatures' annual migration.
When darkness falls, bats emerge from their cave dwellings to forage, relying on the echos of their own calls to locate prey. A new study suggests bats avoid noise overlap in large groups by increasing the volume, duration and repetition rate of their own unique signals.
It seems obvious that camouflage helps animals survive in the wild, but it is a relatively hard thing to test in the wild. A recent study, however, confirms this long-held assumption, proving that disguising one’s body or eggs to match the environment deters predators.
For the first time ever Chinese scientists have created genetically modified monkeys with a human gene for autism. The primates displayed asocial behavior, including becoming stressed when looked in the eye. Researchers from the Institute of Neuroscience in Shanghai hope their findings help treat the disorder in humans.
Bedbugs have built up a resistance to common insecticides due to overuse. Researchers suggest that in order to completely rid our sheets and mattresses of unwanted pests, we need to reevaluate current strategies for fighting them off.
Queen bees and ants emit a chemical that alters their offspring's DNA at birth. This keeps "princesses" sterile and working busily for the colony.
Burn patterns evident on eggshells belonging to ancient, 500-pound flightless Australian birds were recently found by researchers from the University of Colorado Boulder. This suggests early humans hunted the bird and collected its eggs to cook.
A new chameleon species sporting blue spots was recently found in the mountains of Tanzania. Researchers say this find highlights the diversity of animals living in this region.
