Over a decade ago, behavioral ecologist Diane Colombelli-Négrel was wiring superb fairy wrens’ nests to record the birds’ sounds when she noticed something odd. Mother fairy wrens sang while incubating their eggs, even though it would have made more sense to keep quiet to avoid attracting predators.

Paleoanthropologists have sketched a rough timeline of how human evolution played out, centering the early action in Africa.

New research confirms that people lend greater credence to sources of information confirming what they already believe to be true -- or at least what they hope to be true.

Facebook isn’t been open about Instagram’s negative influence

Amidst a sharp increase in deadly wildfires and flooding, increasingly violent storms, and extreme heat, new research published Tuesday found that refusal by governments to act on the climate emergency is causing a widespread sense of hopelessness and eco-anxiety in teenagers and young adults worldwide.

The cancer protein that indicates which tumors are ‘on’ could lead to therapies to keep them ‘off’ forever. A team of scientists from the Lunenfeld-Tanenbaum Research Institute in Canada found a specific protein that turns on cancer in the human body. It is not limited to a specific type of cancerous condition but appears to be common to all variants seen by medicine thus far

A new Yale-led study finds that immune system activity jump-started by rhinovirus exposure could prevent or treat the early stages of COVID-19 infection.

Scientists have uncovered preliminary evidence that oxytocin, a neurohormone that reduces stress and fosters social bonding, could help to reduce dominant behavior in psychopathic offenders. Their findings have been published in the journal Psychoneuroendocrinology.

This doctor wants more emoji in the medical world.

MIT engineers developed a way to grow tiny replicas of the pancreas, using either healthy or cancerous pancreatic cells. Their models could help researchers develop and test potential drugs for pancreatic cancer.

Try as we might, the most advanced synthetic materials pale in comparison to super-strong biological compounds like spider silk and muscle fibers. On that second count, researchers may be closer to growing usable amounts of muscle fiber that can be used in place of fabrics like cotton, silk, and even Kevlar. This could lead to clothing made from real muscle. That might sound like an unsettling option, but the fibers aren’t what you’re imagining.

There's growing demand for healthy feces from human donors to treat C. difficile and other conditions

Losing weight through exercise appears to be more difficult for obese people, research suggests. Initially, researchers thought that the total energy we spend in a day is the sum of energy expended due to activity (ranging from light gardening to running a marathon) and energy used for basic functioning (what keeps us ticking even when we are doing nothing, such as immune function and wound healing).

An experiment that hung rhinoceroses upside down to see what effect it had on the animals has been awarded one of this year's Ig Nobel prizes. Other recipients included teams that studied the bacteria in chewing gum stuck to pavements, and how to control cockroaches on submarines.

Large survey involving two million adults found links between road and rail traffic and Alzheimer’s in particular

The effects of ivermectin therapy on human males can have an effect on men’s reproductive health, according to a 2011 research study performed by three universities in Nigeria. Researchers at the three universities studied the effects of ivermectin, which is used to treat river blindness and other medical conditions in humans, on men’s sperm counts. According to their study, 85 percent of men who take Ivermectin become sterilized.

A cloud of rubidium atoms is said to have achieved the coldest temperature yet after being dropped from the top of a tower.

An avocado a day could help redistribute belly fat in women toward a healthier profile, according to a new study. Women who consumed avocado as part of a daily meal had a reduction in visceral abdominal fat, which forms around the organs deep in the belly.

Scientists say that the recordings are evidence that musk ducks are like parrots in that they are vocal language learners.
