New findings point to an Earth-like environment on ancient Mars

A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake. The results were published today in Journal of Geophysical Research: Planets.

New work reveals the 'quantumness' of gravity

Gravity is part of our everyday life. Still, the gravitational force remains mysterious: to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed by the laws of quantum mechanics.

Archaeology team discovers a 7,000-year-old settlement in Serbia

Together with cooperation partners from the Museum of Vojvodina in Novi Sad (Serbia), the National Museum Zrenjanin and the National Museum Pančevo, a team from the ROOTS Cluster of Excellence has discovered a previously unknown Late Neolithic settlement near the Tamiš River in Northeast Serbia.

New mRNA cancer vaccine triggers fierce immune response to fight malignant brain tumor

In a first-ever human clinical trial of four adult patients, an mRNA cancer vaccine developed at the University of Florida quickly reprogrammed the immune system to attack glioblastoma, the most aggressive and lethal brain tumor.

Scientists show that there is indeed an 'entropy' of quantum entanglement

Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lami from the University of Amsterdam have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of entropy for the phenomenon of quantum entanglement.

Laser excitation of Th-229 nucleus: New findings suggest classical quantum physics and nuclear physics can be combined

Physicists have been hoping for this moment for a long time: For many years, scientists all around the world have been searching for a very specific state of thorium atomic nuclei that promises revolutionary technological applications. It could be used, for example, to build a nuclear clock that could measure time more precisely than the best atomic clocks available today. It could also be used to answer completely new fundamental questions in physics—for example, the question of whether the constants of nature are actually constant or whether they change in space and time.

Citizen scientists help discover record-breaking exoplanet in binary star system

A team of astronomers and citizen scientists has discovered a planet in the habitable zone of an unusual star system, including two stars and potentially another exoplanet.

Mystery behind huge opening in Antarctic sea ice solved

Researchers have discovered the missing piece of the puzzle behind a rare opening in the sea ice around Antarctica, which was nearly twice the size of Wales and occurred during the winters of 2016 and 2017.

A 'cosmic glitch' in gravity: New model may explain strange behavior on a cosmic scale

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a cosmic scale.

Assyriologist claims to have solved archaeological mystery from 700 BC

Ancient symbols on a 2,700-year-old temple, which have baffled experts for more than a century, have been explained by Trinity Assyriologist Dr. Martin Worthington.

Hungry, hungry white dwarfs: Solving the puzzle of stellar metal pollution

Dead stars known as white dwarfs, have a mass like the sun while being similar in size to Earth. They are common in our galaxy, as 97% of stars will eventually become white dwarfs. As stars reach the end of their lives, their cores collapse into the dense ball of a white dwarf, making our galaxy seem like an ethereal graveyard.

Study dispels myth that purebred dogs are more prone to health problems

It's a common belief that purebred dogs are more prone to disease than mixed-breed dogs, but a new study led by researchers at the Texas A&M School of Veterinary Medicine and Biomedical Sciences (VMBS) has busted this myth.

Dying salmon trouble Norway's vast fish-farm industry

They are hailed for their omega-3 fatty acids and micronutrients, but Norway's salmon are not in the best of health themselves at the fish farms where they are bred.

Religious intolerance predicts science denial, surveys suggest

Does being more religious make a person more likely to reject scientific findings? Or is it the level of intolerance of other religions that better predicts rejection of science?

Rock solid evidence: Angola geology reveals prehistoric split between South America and Africa

An SMU-led research team has found that ancient rocks and fossils from long-extinct marine reptiles in Angola clearly show a key part of Earth's past—the splitting of South America and Africa and the subsequent formation of the South Atlantic Ocean.

T. rex not as smart as previously claimed, scientists find

An international team of scientists including two neurobiologists from the University of Alberta is weighing in on the latest controversy over the brain power of Tyrannosaurus rex.

A common type of fiber may trigger bowel inflammation

Inulin, a type of fiber found in certain plant-based foods and fiber supplements, causes inflammation in the gut and exacerbates inflammatory bowel disease in a preclinical model, according to a new study by Weill Cornell Medicine investigators. The surprising findings could pave the way for therapeutic diets that may help ease symptoms and promote gut health. 

Pet parrots prefer live video-calls over watching pre-recorded videos of other birds

Pet parrots given the choice to video-call each other or watch pre-recorded videos of other birds will flock to the opportunity for live chats, new research shows.

Call of the conch: Archaeologists suggest Indigenous Americans used sound to organize local communities

Archaeologists have modeled the auditory range of conch-shell trumpets in the 9th–11th century US Southwest, proposing that the sound was key in the structuring of pre-Columbian Pueblo communities.

After 25 years, researchers uncover genetic cause of rare neurological disease

Some families call it a trial of faith. Others just call it a curse. The progressive neurological disease known as s
