Phys.org / Decoding the DNA switches behind gene regulation

Understanding gene regulation may be key to interpreting human disease genetics. Genes are regulated in part by stretches of DNA called enhancers, which define when, where and how strongly each gene is turned on. Mapping ...

Phys.org / A famous galaxy's black hole has been hiding its most violent behavior

Astronomers have found that a nearby galaxy's black hole is blasting out a far more powerful and hidden gas outflow than previously realized. Studying NGC 1068, a well-known galaxy with an actively feeding black hole at its ...

Phys.org / Moles' wide-armed posture reshapes how their shoulder bones carry loads

While the scapula is the primary bone supporting the body in terrestrial quadrupedal mammals, an analysis of internal bone structure in underground moles (family Talpidae) showed a more important role for the clavicle.

Phys.org / The surprising history of woolly rhinos: They weren't always creatures of the frozen north

Woolly rhinoceroses (Coelodonta antiquitatis) were fascinating creatures: giant, lumbering Ice Age beasts with thick fur and massive horns that died out about 11,000 years ago. Previous genetic studies had left open the question ...

Phys.org / Endurance running or endurance diving—which came first?

A new study combines paleoanthropology and diving physiology to address a fundamental question in human evolution: Why did humans evolve their exceptional aerobic endurance? Did our ancestors begin endurance running to exhaust ...

Phys.org / Bizarre galactic radio source remains active for two decades with no detectable X-rays

Astronomers have identified a peculiar radio transient in the Milky Way that has remained active for more than two decades, defying the behavior expected of known classes of galactic radio sources. The paper posted to the ...

Phys.org / Bone strength study reveals new clues about human evolution

Bipedalism, or walking on two legs, is one of the key features that distinguishes humans from other apes. But when and why our ancestors transitioned from a life often spent in trees to a life spent almost exclusively on ...

Tech Xplore / 'We're losing control': AI pioneer urges nuclear-style safeguards for autonomous agents

The Canadian computer scientist Yoshua Bengio, considered one of the founders of AI, told AFP that humanity is "losing control" of the technology and that the world needs guardrails similar to nuclear arms controls.
