Diverse ancient volcanoes on Mars discovered by planetary scientist may hold clues to pre-plate tectonic activity on Earth

A geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of crust recycling called vertical tectonics. The findings shed light on the ancient crust of Mars and its potential implications for understanding early crustal recycling on both Mars and Earth. Read more ›

Neolithic groups from the south of the Iberian Peninsula first settled permanently in San Fernando (Cadiz) 6,200 years ago

A new study reveals that the first farmers and herdsmen settled in Andalusia collected and consumed shellfish throughout the year, especially in winter. Read more ›

Altermagnetism experimentally demonstrated

Ferromagnetism and antiferromagnetism have long been known to scientists as two classes of magnetic order of materials. Back in 2019, researchers postulated a third class of magnetism, called altermagnetism. This altermagnetism has been the subject of heated debate among experts ever since, with some expressing doubts about its existence. Recently, a team of experimental researchers was able to measure for the first time at DESY (Deutsches Elektronen-Synchrotron) an effect that... Read more ›

The brain is 'programmed' for learning from people we like

Our brains are 'programmed' to learn more from people we like -- and less from those we dislike. This has been shown by researchers in cognitive neuroscience in a series of experiments. Read more ›

A star like a Matryoshka doll: New theory for gravastars

If gravitational condensate stars (or gravastars) actually existed, they would look similar to black holes to a distant observer. Two theoretical physicists have now found a new solution to Albert Einstein's theory of general relativity, according to which gravitational stars could be structured like a Russian matryoshka doll, with one gravastar located inside another.

Root microbes may be the secret to a better tasting cup of tea

You'd think the complex flavor in a quality cup of tea would depend mainly on the tea varieties used to make it. But a new study shows that the making of a delicious cup of tea depends on another key ingredient: the collection of microbes found on tea roots. By altering that assemblage, the authors showed that they could make good-quality tea even better. Read more ›

Ancient retroviruses played a key role in the evolution of vertebrate brains

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is essential for myelin production in mammals, amphibians, and fish. The gene sequence, which they dubbed 'RetroMyelin,' is likely a result of ancient viral infection, and comparisons of RetroMyelin in mammals, amphibians, and fish suggest that retroviral infection and genome-invasion events...

Targeting the microenvironment rather than a specific cell type could be the key to healing injured hearts

A groundbreaking scientific study has unveiled a remarkable discovery that may have far-reaching implications for the treatment of heart disease. The implications are immense offering glimpses of a future where heart disease may no longer be an irreversible condition but a challenge that can be overcome through medical intervention. The potential for developing novel therapies that leverage the body's innate regenerative capacity holds great promise for millions of individuals affected... Read more ›

Exposure to Agent Orange damages brain tissue in ways similar to Alzheimer's disease

Agent Orange, an herbicide used during the Vietnam War, is a known toxin with wide-ranging health effects. Even though Agent Orange has not been used for decades, there is increasing interest in its effects on the brain health of aging veterans. A new study reveals the mechanisms by which Agent Orange affects the brain and how those processes can lead to neurodegenerative diseases. The research shows that exposures to Agent... Read more ›

A new test could predict how heart attack patients will respond to mechanical pumps

Researchers discovered why ventricular assist devices (VADs) used to support the left ventricle of cardiogenic shock patients can induce right ventricle dysfunction. They also developed a test that doctors could use to determine whether this dysfunction will occur. Read more ›

A lighthouse in the Gobi desert

A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.
