A growing understanding of how "reproductive" hormones sculpt the brain could transform the management of neurological conditions.

A new study finds that fragments of tumor DNA in a patient's bloodstream could show that they are at high risk of a melanoma recurrence.

Science writer Mindy Weisberger speaks to Live Science about the parasites that turn their hosts — whether ant, beetle or caterpillar — into zombie-like puppets that act against their own interests.

Fathers exposed to colder temperatures pre-fertilization tend to have children with lower metabolic risk.

Severely dry conditions during the winter of 2013-2014 blocked some species of salmon and steelhead trout from accessing their breeding grounds, wiping out the populations of individual tributaries and even entire watersheds.

The hidden way commercial fishing adds to climate change.

Neuroscience research has only recently begun to prioritize the inclusion of both male and female lab animals in studies. Could we see that shift reverse?

Rat lungworm disease is carried through rodents, slugs, and snails.

Nearly every environment on Earth — and that includes animals — is home to some kind of parasite. We explore parasites not just because they're an

There are so many more questions we have yet to answer in Zoology so grab some fossils, fire up the DNA sequences, and bring your best hypothesis as we

Staffers at Big Bend National Park have discovered a new plant species. The fuzzy white flowering plant is named wooly devil. The post Wooly devil is new plant species discovered at Big Bend first appeared on EarthSky.

This 'devil horned' sunflower is the first plant species described in a US national park in almost 50 years.

Dennis D'Amico, associate professor of animal science, has demonstrated that bacteriophages can effectively reduce the amount of common foodborne pathogens in milk.

Labord's chameleons are only found in Western Madagascar and have developed a live fast die young life cycle to cope with the extreme environmental conditions.

Under the sea ice during the Arctic's pitch-black polar night, cells power photosynthesis on the lowest light levels ever observed in nature.

Evolution was fueled by endosymbiosis, cellular alliances in which one microbe makes a permanent home inside another. For the first time, biologists made it happen in the lab.

Non-native grasses and eucalyptus trees brought to California centuries ago for agriculture and landscaping have reshaped the state's fire dynamics.

Some animals have offspring at an advanced age. Others, on the day that they're born.

Bowhead whales were known to live up to 200 years, and a new study finds that southern right whales may live up to age 150 if they aren't being hunted
