New observations from NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft reveal that the Zwan-Wolf effect — a phenomenon once thought unique to Earth’s magnetosphere, in which charged particles are squeezed like toothpaste coming out of a tube along magnetic structures called flux tubes — is also reshaping the Red Planet’s upper atmosphere. An artistic representation...

Analyzing 1.75-billion-year-old microfossils from ancient Australian seabeds, paleontologists say ancient eukaryotes — the ancestors of every plant, animal and fungus — huddled in oxygenated seafloor patches for over a billion years before breaking free into open water.

A marine biologist studying the photophores of a bioluminescent fish species found needle-shaped guanine crystals that scatter and redirect light instead of merely reflecting it, a discovery that could inspire more efficient biomedical and optical devices.

Tomato-Soy Drink May Help Fight Chronic Inflammation in Adults with Obesity

Tomato-soy juice contains high levels of lycopene and soy isoflavones.

In a small clinical trial, researchers at the Ohio State University found that a tomato juice rich in lycopene and soy isoflavones lowered several proteins linked to chronic inflammation, raising hopes for food-based therapies. Tomato-soy juice contains high levels of lycopene and soy isoflavones. “The idea is, can we use food-based interventions to modulate inflammation?” said Dr. Jessica Cooperstone,...

Scientists have extracted and analyzed proteins from the tooth enamel of six Homo erectus individuals who lived in China roughly 400,000 years ago, offering an unprecedented glimpse into the genetic makeup of one of humanity’s most successful and far-ranging ancestors. Their results suggest that Homo erectus may have carried genetic variants that were later passed to Denisovans and eventually...

Hidden Rift beneath Zambia May Be Tearing Africa Apart

Unusual gases rising from geothermal springs within the Kafue Rift of Zambia suggest a deep fracture in Earth’s crust could mark the early stages of a new tectonic boundary.
