Gravitational waves leave a detectable mark, physicists say
New research shows that gravitational waves leave behind plenty of 'memories' that could help detect them even after they've passed.
Precise temperature measurements with invisible light
Researchers have invented a portable, remarkably stable thermometer capable of measuring temperatures to a precision of within a few thousandths of a degree Celsius.
Stem cell scientists clear another hurdle in creating transplant arteries
Recent work highlights a better way to grow smooth muscle cells, one of the two cellular building blocks of arteries, from pluripotent stem cells. This research is part of an effort to create artery b..
Combat personnel with brain injuries pinpoints abnormal brain waves
A new study finds that veterans and service members with a history of combat-related mild traumatic brain injury have much higher levels of abnormally fast brain waves in a region that plays a key rol..
New brain tumor imaging technique uses protein found in scorpion venom
A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors has shown promise in a clinical trial.
A link between mitochondrial damage and osteoporosis
In healthy people, a tightly controlled process balances out the activity of osteoblasts, which build bone, and osteoclasts, which break it down. Damage to cells' mitochondria can make that proce..
Peering into the past, scientists discover bacteria transformed a viral threat to survive
A study reports the first known evidence of bacteria stealing genetic material from their own worst enemy, bacteriophages, and transforming it to survive.
A deep-dive into the impact of arthritis drugs on gene expression
A new computational framework has revealed key differences between four rheumatoid arthritis medications and their impact on biological pathways in mice.
Antarctic biodiversity hotspots exist wherever penguins and seals poop
Scientists have found that on the desolate Antarctic peninsula, nitrogen-rich poop from colonies of penguins and seals enriches the soil so well that it helps create biodiversity hotspots throughout t..
How the dengue virus replicates in infected cells
The nonstructural protein 1 (NS1) of the dengue virus interacts with another viral protein called NS4A-2K-4B to enable viral replication, according to a new study.
