NASA’s DART asteroid smash shows we could deflect a future threat
NASA’s DART (Double Asteroid Redirection Test) mission did more than alter the motion of a small asteroid. New research shows the spacecraft’s deliberate collision with
Particles may not follow Einstein’s paths after all
One of the biggest unsolved challenges in modern physics is bringing together two powerful theories that describe very different parts of reality. Quantum theory explains
A perfectly balanced atom just broke one of nuclear physics’ biggest rules
For many years, nuclear physicists believed that “Islands of Inversion” were found mainly in isotopes packed with extra neutrons. These unusual regions of the nuclear
Electrons catapult across solar materials in just 18 femtoseconds
Scientists have discovered that electrons can be propelled across solar materials at speeds close to the fastest nature allows, a result that challenges long accepted
Astronomers discover giant cosmic sheet around the Milky Way
Nearly a century ago, astronomer Edwin Hubble discovered that almost all galaxies are receding from the Milky Way. This observation became a cornerstone of modern
Scientists just looked inside Darwin’s 200-year-old specimen jars without opening them
Scientists have found a way to study Charles Darwin’s original specimens from his famous HMS Beagle voyage (1831 to 1836) to the Galapagos Islands. Even
Young cancer survivors face faster aging and possible early dementia
Teens and young adults who survive cancer appear to age more quickly than people their same age who have never had the disease, according to
Massive asteroid impact 6.3 million years ago left giant glass field in Brazil
Scientists have identified Brazil’s first known field of tektites, the glassy material created when an asteroid or other extraterrestrial object strikes Earth with extreme force.
Insomnia and sleep apnea together dramatically raise heart disease risk
Researchers at Yale School of Medicine (YSM) are drawing attention to a powerful and preventable factor in cardiovascular disease. Their findings suggest that improving sleep
Scientists discover microbe that breaks a fundamental rule of the genetic code
One of the most remarkable features of DNA is its precision. Cells read genetic instructions in sets of three letters called codons, and each codon
