Primary care physicians who took an online training course about skin cancer detection significantly improved their skill to properly diagnose and manage benign and malignant lesions, according to an American national study. The physicians’ enhanced skill level also led to a reduction in unnecessary referrals to dermatology...

A team of researchers has found that as cholesterol is metabolized, a potent stimulant of breast cancer is created – one that fuels estrogen-receptor positive breast cancers, and that may also defeat a common treatment strategy for those cancers.

Researchers have identified a chain reaction that triggers the regrowth of some damaged nerve cell branches, a discovery that one day may help improve treatments for nerve injuries that can cause loss of sensation or paralysis.

A researcher has found through studies of pigs' heart valves that age plays a critical role in the valves' progressive hardening, and the problem may be due to the infiltration of a protein known as von Willebrand factor. Tissues from pig valves are commonly used to make human heart-valve...

Federal government changes to Canada's fisheries legislation "have eviscerated" the ability to protect habitat for most of the country's fish species, scientists say in a new study.

A device that could predict when a person with epilepsy might next have a seizure is one step closer to reality thanks to the development of software by researchers in the USA.

A recent prospective, randomized, placebo-controlled clinical trial reports that calcium and vitamin D supplementation improves bone density in a group of male veterans with epilepsy who were treated chronically with antiepileptic drugs. These results suggest that risedronate, a bisphosphonate, may help to prevent new vertebral fractures when taken with calcium and vitamin D...

Cochlear implants allow adults who have become profoundly deaf to recover the ability to understand speech. However, recovery differs between individuals. Activating the visual regions of the brain has proved essential to the satisfactory recovery of hearing, according to a new...

Mine clearing, monitoring of vital signs and robot vision are among the many potential applications for Novelda’s innovative radar technology. The company’s tiny, unique processor chips are at the core of it all.

Cancer patients have the highest probability of recovering if tumors are completely removed. However, tiny clusters of cancer cells are often difficult for surgeons to recognize and remove. A camera makes hidden tumors visible during an operation.

For the first time, researchers have discovered that at least in ants, animals can change their decision-making strategies based on experience. They can also use that experience to weigh different options.

Researchers have created an implantable bio patch that regrows bone in a living body, using existing cells. The team created a scaffold seeded with plasmids containing the genetic information for producing bone. The plasmids are absorbed by bone cells already in the body, spurring new growth. Potential applications extend to...

Experts in anthropology and cybersecurity are examining the unspoken knowledge shared by cybersecurity analysts as a way to develop new automated tools that help analysts strengthen their cyber defenses.

Veterinary scientists have developed a diagnostic test that can detect emerging strains of canine parvovirus, a severe --- and potentially fatal -- virus that affects dogs.

Personality research shows outright requests, rather than the door-in-the-face strategy may be more effective for fundraisers.

Research has found that viability, necrosis, and death of immune cells are influenced by BPA concentrations in components of dialysis machines. Alternative polymers for dialysis machine components may reduce cells’ exposure to BPA during dialysis.

An Australian research team has investigated the threat horse riding poses to the ecology of national parks around the world. And it seems there's a growing problem in horse dung.

A research group has taken an unconventional approach to finding new compounds with therapeutic relevance by launching a crowdsourcing initiative with citizen scientists from around the country. Researchers team with the public to sample soils from all across the United States for the purpose of identifying new microorganisms that produce drug-like...

Astronomers have ruled out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don't explain the cosmic speed-up, they eliminate one provocative possibility that our planet, solar system and galaxy are at the center of the universe and that there is no dark...

Apps often read the data from mobile user devices unnoticed by users. This represents a large security risk, especially for companies. A new App-Store filters out problematic Android applications automatically with the help of detection software.

When a person is deemed trustworthy, we perceive that person's face to be more similar to our own, according to a new study.

Nanoparticles, which range from 1-100 nanometers in size, are roughly the same size as biomolecules such as proteins, antibodies, and membrane receptors.  Because of this size similarity, nanoparticles can mimic biomolecules and therefore have a huge potential for application in the biomedical field. Scientists have now designed and created multicomponent nanoparticles with specific shapes and...

The Hartz IV reform of the German labor market has been one of the most controversial reforms in the history of the reunited Federal Republic of Germany. It has been widely seen as the end of the welfare state leading into poverty. At the same time, Germany has been able to reduce its unemployment rate over the last years more than almost any other European or OECD member country. What role did...

Moving wheeled hospital beds from one place to another is a laborious and time-consuming task. This is made more cumbersome by complicated hospital layouts that often feature narrow corridors, tight elevators and crowded rooms. It takes a minimum of two staff to transport a bed – one at the back to push the bed, and one in the front to provide direction. A shortage of hospital staff is one of...
