Hundreds of endangered Australian Green and Golden Bell frogs huddle inside a sauna, shielded from Sydney's winter chill.

The sauna -– a small greenhouse containing black-painted bricks warmed by the sun -- may be pleasant, but it also protects the frogs from a deadly chytrid fungus that would otherwise drive them to extinction.

Naming others is considered a marker of highly advanced cognition in social animals, previously observed only in humans, bottlenose dolphins and African elephants.

Marmoset monkeys have now joined this exclusive club, according to a new study published in Science on Thursday.

Mammals, from the mighty blue whale to the tiny shrew, inhabit nearly every corner of our planet. Their remarkable adaptability to different environments has long fascinated scientists, with each species developing unique traits to survive and thrive.

Despite such vast biological diversity, it was believed until recently that the structure and function of the heart across mammals was the same. But research from my colleagues and I reveals that the human heart is an outlier, distinctly different from those of our closest relatives, the great apes, including chimpanzees, bonobos, orangutans and gorillas.

As we grieve the loss of a pet, we may not be the only ones feeling the pain. Research is showing that cats who are left behind when another animal in their home dies could be mourning along with us.

Grief is a well-documented human response to loss – but its roots may be far more ancient as some scientists believe it evolved in extinct species of humans. Corvids – members of the crow family – primates, and marine mammals like dolphins and whales, have all been observed to change their behaviour when one of their own dies, from carrying dead offspring for days, to staying close by the body, as if keeping vigil.

In 2005, I was navigating winding roads through the Drakensberg Mountains, in Lesotho, Southern Africa. Towering cliff-like features known as escarpments interrupt the landscape, rising up by a kilometer or more. Taken aback by the dramatic scenery, I was struck by a question: how on Earth did it form?

The outer shell of our planet is fractured into seven or eight major sections, or tectonic plates, on which the continents sit. We expect to see the continents rise up at the active boundaries of these plates, where volcanism and earthquakes are often concentrated.

The FDA has approved an updated covid shot for everyone 6 months old and up, which renews a now-annual quandary for Americans: Get the shot now, with the latest covid outbreak sweeping the country, or hold it in reserve for the winter wave?

The new vaccine should provide some protection to everyone. But many healthy people who have already been vaccinated or have immunity because they’ve been exposed to covid enough times may want to wait a few months.

The conditions within a person’s home, family and community affect their ability to stay healthy. Scientists studying these social determinants of health are trying to understand whether nature or nurture has a stronger effect on a person’s ability to fight disease.

I am a developmental physiologist studying the ways that drinking affects fetal development and lifelong health. Although researchers have long recognized that a father’s alcohol abuse negatively affects his children’s mental health and social development, it hasn’t been clear if paternal drinking has any lasting biological effects on his offspring’s physical health.

A person in the northeastern U.S. state of New Hampshire has died after contracting the rare mosquito-borne eastern equine encephalitis (EEE) virus, health authorities announced Tuesday.

The patient, identified only as an adult from the town of Hampstead, was hospitalized with severe central nervous system disease and later succumbed to the illness, the New Hampshire Department of Health and Human Services (DHHS) said in a statement.

SpaceX on Tuesday postponed once more its attempt at launching a daring orbital expedition featuring an all-civilian crew that is aiming to carry out the first-ever spacewalk by private citizens.

The Polaris Dawn mission, organized by billionaire entrepreneur Jared Isaacman, had been set to lift off from NASA's Kennedy Space Center in Florida during a four-hour window early Wednesday.

People with brain lesions are more susceptible to religious fundamentalism, according to a study authored by a Harvard University neurology instructor.

Michael Ferguson, an instructor at Harvard Medical School, published a paper along with several other academic experts on brain research about the impact of religious fundamentalism on those with brain lesions.

As 55 million people in the U.S. Midwest faced heat alerts on Monday, research published in the peer-reviewed Journal of the American Medical Association showed that heat-related deaths in the country rose 117% between 1999 and 2023.

"The current trajectory that we're on, in terms of warming and the change in the climate, is starting to actually show up in increased deaths," lead author Jeffrey Howard, an associate professor of public health at the University of Texas at San Antonio, toldUSA Today. "That's something that we hadn't had measured before."

Climate change is fuelling an alarming increase in deadly lightning strikes in India, killing nearly 1,900 people a year in the world's most populous country, scientists warn.

Lightning caused a staggering 101,309 deaths between 1967 and 2020, with a sharp increase between 2010 and 2020, a team of researchers led by Fakir Mohan University in the eastern state of Odisha said.

SpaceX on Monday pushed back the historic launch of an all-civilian crew on an orbital expedition set to mark a new chapter in space exploration with the first spacewalk by private citizens.

The Polaris Dawn mission, organized by billionaire entrepreneur Jared Isaacman, was set to lift off early Tuesday from NASA's Kennedy Space Center, but is now targeting early Wednesday after a late technical hitch.
