What happened to the sun over 7,000 years ago?

Researchers have identified a new type of solar event and dated it to 5480 BC using carbon-14 levels in tree rings. The team proposes causes for the event, extending knowledge of the sun's behavior and its effects on Earth. The study provides new insights into the sun's activity during the mid-Holocene period.

Picking teams and picking music in P.E.

BYU professor David Barney's research shows that playing music in P.E. class can significantly improve outcomes, making kids 5.87 times more likely to enjoy physical activity. Publicly picking teams, on the other hand, has a negative associative effect on children, leading to lower self-esteem and decreased confidence.

Scripps Florida scientists find clue to why Zika, but not its close relatives, causes birth defects

Researchers discovered that human umbilical endothelial cells are more susceptible to Zika infection, allowing it to access the fetal bloodstream. The virus uses a cell surface molecule called AXL to exploit a secret passage, enabling it to cause birth defects such as microcephaly and eye damage.

The solution from the skies to save endangered species

A new project from Liverpool John Moores University is using drones equipped with thermal cameras to help identify endangered species, such as rhinos and orang-utans. The technique involves analyzing thermal heat profiles to create a unique 'fingerprint' for each animal, allowing for more efficient conservation efforts.

Novel combination therapy overcomes difficult-to-treat form of antibiotic resistance

Researchers have discovered a novel combination therapy that successfully treats infections caused by a pernicious form of antibiotic resistance. The treatment regimen, which includes ceftazidime/avibactam and aztreonam, overcomes the resistance caused by metallo-ß-lactamases, a growing global public health problem.

The power of tea

Researchers found that a green tea compound may prevent light chain amyloidosis, a condition where parts of the body's own antibodies become misshapen and accumulate in organs, by transforming the protein into a non-toxic form. The study suggests potential lifesaving benefits for patients with multiple myeloma and amyloidosis.

Body dysmorphic disorder may be under-diagnosed in patients seeking cosmetic procedures

A survey study found that cosmetic professionals are often unaware of the true prevalence of body dysmorphic disorder (BDD) in patients seeking cosmetic procedures. Most respondents were familiar with BDD and its criteria, but only a small percentage routinely addressed body image problems or collaborated with psychologists.

Online Pest Risk Atlas for Africa to combat climate change effects on pest management

The International Potato Center launched an online mobile-accessible Pest Risk Atlas for Africa to assess potential pest risks under current and future climate conditions. The atlas provides detailed information for pest risk analysis, including detection and identification, means of movement and dispersal, and phytosanitary measures.

How does the brain make perceptual predictions over time?

Neuroscientist David Heeger proposes a new theory that explains how the brain uses prediction and inference to make decisions. The brain's neural network can process sensory input in a feedforward manner, but also runs in a feedback mode to generate predictions, and combines both modes for optimal performance.

UTSW identifies ion channel necessary for hormone and anti-obesity drug to suppress eating

Researchers at UT Southwestern Medical Center identified an ion channel, TrpC5, essential for the brain's response to leptin and lorcaserin, two hormones and medications used to suppress appetite and reduce body weight. In mice deficient in TrpC5, these hormones were ineffective, leading to increased body weight and disrupted metabolism.
