Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found an enormous black hole in the early Universe that appears to predate its own host galaxy, raising fresh questions about how the cosmos’ first supermassive monsters were born.

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...

490-Million-Year-Old Arthropod Fossil Fills Puzzling Gap in Fossil Record

A new species of corcoraniid arthropod that lived during the Furongian epoch, between 497 and 487 million years ago, has been identified from an exceptionally preserved specimen found near Québec, Canada. The discovery supports the view that the so-called Furongian Gap — an evolutionary interval between the Cambrian Explosion and the Great Ordovician Biodiversification Event characterized...

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.

Is Dark Energy Unnecessary? Mathematicians Challenge Standard Cosmological Model of Universe

This artist’s impression shows the evolution of the Universe beginning with the Big Bang on the left followed by the appearance of the Cosmic Microwave Background. The formation of the first stars ends the cosmic dark ages, followed by the formation of galaxies. Image credit: M. Weiss / Harvard-Smithsonian Center for Astrophysics.

Mathematicians from University College London and the University of California, Davis, have published a mathematical proof that the Universe’s accelerating expansion can be explained without dark energy, dealing a serious blow to the Lambda-cold dark matter model — the standard cosmological model that has stood for nearly 30 years. Alexander et al. provide a mathematical proof that instabilities...

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

Location map of the extensional zone within the Central African Plateau of Zambia. The Kafue Rift is connected to the Luano and Luangwa rifts to the NE, and the Western branch of the EARS at the Rukwa rift (RRB) and Rungwe Volcanic Province (RVP).

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.
