Improved avenues to train plastic surgeons in microsurgery
- ScienceDaily
- 19/10/25 23:08
Microsurgery is an intricate and challenging surgical technique that involves using miniature instruments and sutures as fine as a hair strand aided by sophisticated microscopes. In plastic surgery, microsurgery is used to repair small damaged vessels and nerves following trauma, or in reconstructive procedures by moving a component of living tissue from one place of the body to another and...
Microscale rockets can travel through cellular landscapes with precision

Discovery in monkeys could lead to treatment for blindness-causing syndrome
- ScienceDaily
- 19/10/25 20:53
A genetic mutation that leads to a rare, but devastating blindness-causing condition called Bardet-Biedl Syndrome has been discovered in monkeys for the first time. The finding offers a promising way to develop gene and cell therapies that could treat people with the condition, which leads to vision loss, kidney disfunction, extra fingers or toes, and other symptoms.
Micromotors push around single cells and particles
- ScienceDaily
- 19/10/25 20:53
A new type of micromotor -- powered by ultrasound and steered by magnets -- can move around individual cells and microscopic particles in crowded environments without damaging them. In one demonstration, a micromotor pushed around silica particles to spell out letters. Researchers also controlled the micromotors to climb up microsized blocks and stairs, demonstrating their ability to move over...

Electrospun fibers weave new medical innovations
- ScienceDaily
- 19/10/25 20:52
Scientist are developing new applications for a fabrication process called coaxial electrospinning, which combines two or more materials into a fine fiber for use in industry, textiles or even medicine. Electrospinning combines the amazing properties of one material with the powerful benefits of another.
Nerve cell protection free from side effects
- ScienceDaily
- 19/10/25 19:04
The hormone erythropoietin (Epo) is a well-known doping substance that has a history of abuse in endurance sports. In addition to promoting red blood cell production, Epo protects nerve cells from death. To use this effect to cure neurodegenerative diseases, negative effects need to be prevented. Researchers have now discovered another Epo receptor that could have protective effects in humans...
Putting the 'bang' in the Big Bang
- ScienceDaily
- 19/10/25 19:04
Physicists have simulated in detail an intermediary phase of the early universe that may have bridged cosmic inflation with the Big Bang. This phase, known as ''reheating,'' occurred at the end of cosmic inflation and involved processes that wrestled inflation's cold, uniform matter into the ultrahot, complex soup that was in place at the start of the Big Bang.
Reframing Antarctica's meltwater pond dangers to ice shelves and sea level
- ScienceDaily
- 19/10/25 19:04
On Antarctica, meltwater ponds riddle a kilometer-thick, 10,000-year-old ice shelf, which shatters just weeks later. The collapse shocks scientists and unleashes the glacier behind the ice shelf, driving up sea level. A new study puts damage by meltwater ponds to ice shelves and the ensuing threat to sea level into cool, mathematical perspective.
Can solar technology kill cancer cells?
- ScienceDaily
- 19/10/25 19:04
Scientists have revealed a new way to detect and attack cancer cells using technology traditionally reserved for solar power. The results showcases dramatic improvements in light-activated fluorescent dyes for disease diagnosis, image-guided surgery and site-specific tumor treatment.
Energy regulation rollbacks threaten progress against harmful ozone
- ScienceDaily
- 19/10/25 17:30
The fight against harmful ozone is under legal threat. Air quality and carbon emissions regulations are currently in limbo in courts and congress, from core legislation from the 1970s to rules from the last US administration. This study models the future losses in the fight to drive down respiratory-damaging ozone if the regulations go away.
High fiber, yogurt diet associated with lower lung cancer risk

A diet high in fiber and yogurt is associated with a reduced risk for lung cancer.
Fire-spawned forest fungi hide out in other organisms
- ScienceDaily
- 19/10/25 17:30
When a wildfire obliterates a forest, the first life to rise from the ashes is usually a fungus - one of several species that cannot complete its life cycle in the absence of fire. Scientists have long argued about where and how such pyrophilous (fire-loving) fungi survive, sometimes for decades, between fires. A new study finds that some of these fungi hide out in the tissues of mosses and...
