Improved avenues to train plastic surgeons in microsurgery

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...

Engineers develop a new way to remove carbon dioxide from air

A new way of removing carbon dioxide from a stream of air could provide a significant tool in the battle against climate change. The new system can work on the gas at virtually any concentration level, even down to the roughly 400 parts per million currently found in the atmosphere.

Platform for scalable testing of autonomous vehicle safety

In the race to manufacture autonomous vehicles (AVs), safety is crucial yet sometimes overlooked as exemplified by recent headline-making accidents. Researchers are using artificial intelligence (AI) and machine learning to improve the safety of autonomous technology through both software and hardware advances.

Discovery in monkeys could lead to treatment for blindness-causing syndrome

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

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

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

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

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

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?

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

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.

Fire-spawned forest fungi hide out in other organisms

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...

Not all hypertension drugs are created equal, reports big-data study

For those with extremely high blood pressure, or hypertension, there are many initial medication options -- so many that it can be hard to know which one to use. Now, a new article provides more information about the relative safety and effectiveness of different hypertension drugs in order to inform this critical treatment decision. The study reveals that angiotensin converting enzyme (ACE)...

Insect evolution during the Eocene epoch

Scientists have shown that the incidence of midge and fly larvae in amber is far higher than previously thought. The new finds shed light on insect evolution and the ecology in the Baltic amber forest during the Eocene epoch.

What 26,000 books reveal when it comes to learning language

What can reading 26,000 books tell researchers about how language environment affects language behavior? Scientists have completed a computational modeling study that suggests our experience and interaction with specific learning environments, like the characteristics of what we read, leads to differences in language behavior that were once attributed to differences in cognition.

Brown and white body fat speak different languages

Most adults have two types of body fat: white and brown. New research has shown that the two types of fat secrete different sets of proteins. This means that white and brown fat don't speak the same language when they communicate with the rest of the body.
