Scientists find evidence that Venus has active volcanoes

New research led by Universities Space Research Association (USRA) and published today in Science Advances shows that lava flows on Venus may be only a few years old, suggesting that Venus could be volcanically active today—making it the only planet in our solar system, other than Earth, with recent eruptions.

The case of the elusive Majorana: The so-called 'angel particle' is still a mystery

A 2017 report of the discovery of a particular kind of Majorana fermion—the chiral Majorana fermion, referred to as the "angel particle"—is likely a false alarm, according to new research. Majorana fermions are enigmatic particles that act as their own antiparticle and were first hypothesized to exist in 1937. They are of immense interest to physicists because their unique properties could...

Study: US presidents play surprising role in driving corporate social responsibility

A new study by San Francisco State University Assistant Professor of Management Nara Jeong suggests that CEOs look to the White House for leadership on social responsibility—but not the way you might expect. It turns out that corporate leaders are less likely to act on their values when they're in agreement with the president. And their social responsibility efforts increase when they don't...

Less offspring due to territorial conflicts

Both humans and chimpanzees can be extremely territorial, and territorial disputes between groups can turn violent, with individuals killing each other. In humans, such between-group competition can escalate to war and devastating loss of human life. Researchers from the Max Planck Institute for Evolutionary Anthropology studied wild Western chimpanzees to find out whether territorial behavior may...

Why more couples are choosing to live apart

For many couples, moving in together signifies a big step in the relationship. Traditionally, this meant marriage, although nowadays most cohabit before getting married, or splitting up. But there is a third choice: living apart together.

Planetary nebula WR 72 has hydrogen-poor knots, study finds

Using the Southern African Large Telescope (SALT), astronomers have conducted spectroscopic and imaging observations of the planetary nebula WR 72. They discovered hydrogen-poor knots in the central part of the nebula, which could be helpful in improving knowledge about the nature of this object. The finding is detailed in a paper published December 23 on arXiv.org.

Ferocious fires in Australia intensify

As the New Year starts, the outlook for the bushfire situation in Australia continues to be grim. These huge and disastrous fires continue to burn ferociously and with abandon, and reports have come out that the fires have actually intensified in the last 12 hours. NOAA-NASA's Suomi NPP satellite captured imagery of the fires and the resultant billowing smoke cascading off the edge of Australia on...

'Super' simulations offer fresh insight into serotonin receptors

Scientists at the University of Maryland (UMD) and the National Institute of Standards and Technology (NIST) have discovered a way to detect the molecular mechanism by which 5HT3A, a serotonin receptor located at the neuron synapse, is activated. Having a molecular model of this activation will allow the testing of pharmaceuticals inhibitors using computer models instead of traditional...

Amazing cows hold promise in pioneering sustainable food systems of the future

In today's climate change narrative, animal-based agriculture often endures criticism for its alleged contributions to the global problem. With some naysayers ranking the industry second only to the population explosion as a root contributor to global warming and other weather-related devastation, the concern for how food is—and can be—produced has become even more pressing.

Research sheds light on the moon's dark craters

The next wave of robots to fly to Mars in 2020 could offer scientists an unprecedented understanding of Earth's closest neighboring planet. But there are still mysteries to be solved much closer to home, on Earth's own moon.

Ashes to ashes, dust to ... compost? An ecofriendly burial in just 4 weeks

In Australia, interment in a cemetery or a churchyard has been the most common choices for in-ground burial. Over the past 20 years, though, burial has become a less accessible and more costly option for many people. This is because increasing numbers of deaths have created a boom in demand for burial plots and cemeteries are fast running out of space.

Indigenous song keepers reveal traditional ecological knowledge in music

Since the beginning of time, music has been a way of communicating observations of and experiences about the world. For Indigenous Peoples who have lived within their traditional territories for generations, music is a repository of ecological knowledge, with songs embedding ancestors' knowledge, teachings and wisdom.
