The mass extinction at the end of the Permian Period 252 million years ago — one of the great turnovers of life on Earth — appears to have played out differently and at different times on land and in the sea, according to newly redated fossils beds from South Africa and Australia.
Dineobellator notohesperus lived 67 million years ago.
For the first time, more 360 scientists from 184 different institutions have contributed to a global effort to find more than 200 regions of the genome and more than 300 specific genetic variations that affect the structure of the cerebral cortex and likely play important roles in psychiatric and neurological conditions.
A new project is an effort to combat the rise of coordinated social media campaigns to incite violence, sew discord and threaten the integrity of democratic elections.
Micro-CT scanning of “Little Foot” skull reveals new aspects of the life of this more than 3-million year-old-human ancestor.
Scientists have discovered a possible link between Parkinson’s disease and a gene impacted by a neurotoxin found in blue-green algae.
Turtle ant soldiers and their oddly-shaped heads suggest that evolution is not always a one-way street toward increasing specialization.
Using data from the Dark Energy Survey, researchers have found and cataloged more than 300 minor planets beyond Neptune, including more than 100 new discoveries. This updated catalog of trans-Neptunian objects, and the methods used to find them, could aid in future searches for undiscovered planets in the far reaches of the solar system.
Researchers using ESO’s Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets.
Earth turned faster at the end of the time of the dinosaurs than it does today, rotating 372 times a year, compared to the current 365, according to a new study of fossil mollusk shells from the late Cretaceous. The new measurement informs models of how the Moon formed and how close to Earth it has been over the 4.5-billion-year history of the Earth-Moon gravitational dance.
Astronomers have captured a truly incredible image of two stars locked in a fight to the death, producing a stunning, if violent, cosmic masterpiece in the process.
The record-setting stellar explosion SN 2006gy was 50 billion times brighter than our sun, with a blast so energetic it baffled the scientific community. Now scientists think they have uncovered what made it so incredibly bright.
The Institut Pasteur has sequenced the whole genome of the coronavirus known as ‘2019-nCoV’, becoming the first institution in Europe to sequence the virus since the start of the outbreak.
Previous studies have shown how the SARS virus (SARS-CoV) interacts with animal and human hosts in order to infect them. The mechanics of infection by the Wuhan coronavirus appear to be similar.
The most distant dying galaxy discovered so far, more massive than our Milky Way — with more than a trillion stars — has revealed that the ‘cores’ of these systems had formed already 1.5 billion years after the Big Bang, about 1 billion years earlier than previous measurements revealed.
