One of the largest ever land mammals evolved into extinct dwarf elephant
Sicilian dwarf elephant Palaeoloxodon cf. mnaidriensis lived on the island of Sicily and went extinct 19,000 years ago. A new study shows that an extinct...
Geochemical study confirms cause of end-Permian mass extinction event
Researchers found a direct link between global dispersion of nickel-rich aerosols, ocean chemistry changes and the end-Permian mass extinction event that took place 251...
Meringue-like material could make aircraft as quiet as a hairdryer
Scientists have developed a material to make jet engines as quiet as a hairdryer. The material is incredibly light, meringue-like material cuts aircraft noise...
‘Doomsday Glacier’ may be more stable than initially feared
Study sheds light on the future of the massive Thwaites Glacier. Researchers discover that instability doesn't always lead to rapid disintegration. This is the...
Hubble data confirms galaxies lacking dark matter
The most accurate distance measurement yet of ultra-diffuse galaxy (UDG) NGC1052-DF2 (DF2) confirms beyond any shadow of a doubt that it is lacking in...
Physicists bring human-scale object to near standstill, reaching a quantum state
Scientists at MIT and elsewhere have cooled a large, human-scale object to close to its motional ground state. Achieving this state involves super-cooling objects so that...
Researchers uncover unique properties of a promising new superconductor
A study led by physics researchers has discovered that a unique superconducting metal is more resilient when used as a very thin layer.
An international...
Mystery of Betelgeuse’s dip in brightness solved
A team of astronomers have now published new images of the star’s surface, taken using the European Southern Observatory’s Very Large Telescope (ESO’s VLT),...
Largest structures in the universe show clear light-shifted signal of rotation
Galaxies reside in filaments hundreds of millions of light-years long, on a backbone of dark matter. And, where those filaments meet, there are galaxy...
Study: Half of US cosmetics contain toxic chemicals
More than half the cosmetics sold in the United States and Canada likely contain high levels of a toxic industrial compound linked to serious...
The sun’s clock: New calculations support and expand planetary hypothesis
Not only the 11-year cycle, but also all other periodic solar activity fluctuations can be clocked by planetary attractive forces. With new model calculations,...
