From dandruff to deep sea vents, an ecologically hyper-diverse fungus

From dandruff to deep sea vents, an ecologically hyper-diverse fungus

A ubiquitous skin fungus linked to dandruff, eczema and other itchy, flaky maladies in humans has now been tracked to even further global reaches — including Hawaiian coral reefs and the extreme environments of arctic soils and deep sea vents. A review in the scientific journal PLOS Pathogens considers the diversity, ecology, and distribution of the fungi of the genus Malassezia in light of new insights gained from screening environmental sequencing datasets from around the world.

Treating pain by blocking the ‘chili-pepper receptor’

Treating pain by blocking the ‘chili-pepper receptor’

As anyone who has bitten into a chili pepper knows, its burning spiciness — though irresistible to some — is intolerable to others. Scientists exploring the chili pepper’s effect are using their findings to develop a new drug candidate for many kinds of pain, which can be caused by inflammation or other problems. They reported their progress on the compound, which is being tested in clinical trials, in ACS’ Journal of Medicinal Chemistry Continue reading

Why aren’t pregnant women getting flu vaccine?

Why aren’t pregnant women getting flu vaccine?

Both mother and fetus are at increased risk for complications of flu infection during pregnancy. And prenatal care providers say they’re advising women to get the flu vaccine, in line with recommendations from various organizations. Continue reading

Quasi-legal drug 15 times stronger than heroin hides in plain sight

Quasi-legal drug 15 times stronger than heroin hides in plain sight

Emergency physicians should expect “an upswing in what on the surface appear to be heroin overdoses,” but are actually overdoses tied to acetyl fentanyl, an opiate that is mixed into street drugs marketed as heroin. The looming threat of another unregulated quasi-legal drug is detailed today online in Annals of Emergency Medicine . “What’s frightening about this emerging street drug is that users themselves may not be aware that they are ingesting it,” said lead study author John Stogner, Ph.D Continue reading

Study details shortage of replication in education research

Study details shortage of replication in education research

Although replicating important findings is essential for helping education research improve its usefulness to policymakers and practitioners, less than one percent of the articles published in the top education research journals are replication studies, according to new research published today in Educational Researcher ( ER ), a peer-reviewed journal of the American Educational Research Association. “Facts Are More Important Than Novelty: Replication in the Education Sciences,” by Matthew C. Continue reading

NSAIDs may lower breast cancer recurrence rate in overweight, obese women

NSAIDs may lower breast cancer recurrence rate in overweight, obese women

Recurrence of hormone-related breast cancer was cut by half in overweight and obese women who regularly used aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs), according to data published in Cancer Research , a journal of the American Association for Cancer Research. Continue reading

Long antibiotic treatments: Slowly growing bacteria to blame

Long antibiotic treatments: Slowly growing bacteria to blame

Whether pneumonia or sepsis — infectious diseases are becoming increasingly difficult to treat. One reason for this is the growing antibiotic resistance. But even non-resistant bacteria can survive antibiotics for some time, and that’s why treatments need to be continued for several days or weeks Continue reading

Scientists boost potential of passive immunization against HIV

Scientists boost potential of passive immunization against HIV

Scientists are pursuing injections or intravenous infusions of broadly neutralizing HIV antibodies (bNAbs) as a strategy for preventing HIV infection. This technique, called passive immunization, has been shown to protect monkeys from a monkey form of HIV called simian human immunodeficiency virus, or SHIV. To make passive immunization a widely feasible HIV prevention option for people, scientists want to modify bNAbs such that a modest amount of them is needed only once every few months.

Predictors of prospective memory deficit post TBI identified by researchers

Predictors of prospective memory deficit post TBI identified by researchers

Kessler Foundation scientists have identified predictors of prospective memory impairment after traumatic brain injury (TBI). Findings were epublished on July 28 by the Journal of the International Neuropsychological Society. The article, “Rule monitoring ability predicts event-based prospective memory performance in individuals with TBI,” is authored by Jessica Paxton, PhD, and Nancy Chiaravalloti, PhD, of Kessler Foundation Continue reading
