USC researchers, studying bones at the L.A. County Natural History Museum, have found evidence of a fearsome shark taking to the sky to take down a pterosaur, a formidable flying reptile. It was a prehistoric clash of the ages that didn’t end pretty when a monster in the sky clashed with the beast of the deep. The ...
New research led by astrophysicists at Durham University, UK, predicts that the Large Magellanic Cloud (LMC) could hit the Milky Way in 2 billion years’ time. The collision could occur much earlier than the predicted impact between the Milky Way and another neighboring galaxy, Andromeda, which scientists say will hit our galaxy in 8 billion years. ...
Earlier this year, the United Nations announced some much-needed positive news about the environment: The ozone layer, which shields the Earth from the Sun’s harmful ultraviolet radiation, and which was severely depleted by decades of human-derived, ozone-destroying chemicals, is on the road to ozone recovery. The dramatic turnaround is a direct result of regulations set ...
An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation’s (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF’s Kitt Peak National Observatory (KPNO), is thought to herald the birth of a new black hole or neutron star, caught at the exact moment of its creation. Observations ...
Using data from NASA’s Kepler space telescope, citizen scientists have discovered a new world, a planet roughly twice the size of Earth located within its star’s habitable zone, the range of orbital distances where liquid water may exist on the planet’s surface. The new world, known as K2-288Bb, could be rocky or could be a gas-rich ...
Simply reducing greenhouse gas emissions probably is not going to be sufficient for the planet to escape catastrophic damage from climate change, scientists say. Additional actions will be required, and one option is solar geoengineering, which could lower temperatures by methods such as reflecting sunlight away from the Earth through the deployment of aerosols in ...
Living with Alzheimer’s disease can be tough. The possibility that you might end up not remembering the faces of the people you love most can cause sleepless nights for many Alzheimer’s patients. To help such people, a 14-year old girl, Emma Yang, is creating a smartphone app called “Timeless.” The app for Alzheimer’s patients “Timeless ...
An international team of astronomers, including from the University of Cambridge, discovered the massive object when trawling through data from the European Space Agency’s Gaia satellite. The object, named Antlia 2 (or Ant 2), has avoided detection until now thanks to its extremely low density as well as a perfectly chosen hiding place, behind the ...
Astronomers have found what could be one of the universe’s oldest stars, a body almost entirely made of materials spewed from the Big Bang. The discovery of this approximately 13.5 billion-year-old tiny star means more stars with very low mass and very low metal content are likely out there — perhaps even the universe’s very ...
A new national study out of Ohio State University shows that people whose mothers had more romantic partners — married or cohabiting — often follow the same path. Results suggest that mothers may pass on personality traits and relationship skills that make their children more or less likely to form stable relationships. Claire Kamp Dush, ...
