A cataclysmic collision in space provides new clues on astronomy's biggest stalemate

Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.

Sound waves reconstruct Alaska fireball path after cameras miss key details

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something else: low-frequency sound waves that traveled hundreds of

Can AI plan for heat emergencies better than simple rules? It depends

The thermometer reads 95°F (35°C) in Brooklyn, and vulnerable individuals need information to take appropriate action. New York City officials must gather facts quickly to provide updates on cooling centers, power outages and other details that could save lives. Are these details

Evolutionary origins of 'junk DNA' may provide new clues to cancer

In cancer research, one person's junk is increasingly becoming another person's treasure. Scientists have uncovered new evidence showing how recently evolved "junk DNA" genetic elements can become integrated into ancient cellular pathways that regulate cancer. These findings may

Harsh UVB bursts leave tadpoles with more DNA damage than longer exposure

Sunburn is a serious problem in the Southern Hemisphere, where depleted ozone provides less protection from UVB. Tadpoles are at particular risk because they are growing rapidly, making them vulnerable to UVB DNA damage. Niclas Lundsgaard of The University of Queensland (UQ), Aus

Climate change may prop up urban plant growth in the face of development—provided cities b

Worsened drought stress, changing rainfall patterns, flowers and pollinators thrown out of sync: These only scratch the surface of the ways climate change challenges plant life. But warmer air and higher carbon dioxide levels can also fuel faster plant growth, limit plants' water

Synchronized infrared lasers control molecular shape changes and expose hidden fingerprint

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different structural conformations. Their study provides a new wind
