The new exercise HIT: do less

A new study published in The Journal of Physiology found that short-term high-intensity interval training (HIT) can be an effective alternative to traditional long-term exercise. By incorporating brief bursts of intense exercise, individuals can improve muscle function and burn fat without needing extensive exercise time.

A golden bullet for cancer

Researchers at Washington University in St. Louis have developed gold nanocages that selectively accumulate in tumors and convert laser light to heat, killing malignant cells. The treatment avoids warm surrounding tissue, making it a promising approach for cancer therapy.

Look at Mie!

A Rice University team re-examined Gustav Mie's century-old equations for electromagnetic wave interaction with spherical metal particles. The researchers found that average properties matched the predictions, but individual particles deviated significantly due to shape and orientation variations on the substrate.

Securities analysts' reports new technology slow adoption, warns study in INFORMS journal

A new study in Organization Science journal suggests that securities analysts' reluctance to recommend investment in new technologies can harm veteran companies. The researchers found that analysts prefer strategies that extend existing technologies over those that directly respond to new technology, with negative implications for mana...

ATS issues statement on disorder of respiratory and autonomic nervous system regulation

The American Thoracic Society has released new guidelines for CCHS, citing crucial discoveries linking the condition to mutations in the PHOX2B gene. Affected individuals require fastidious medical supervision to attain optimal quality of life, and early identification and intervention are critical.

Preventing gastric cancer with antibiotics

A large multicenter trial in Japan found that patients with early gastric cancer who received H. pylori antibiotics after surgical resection had a significantly lower risk of developing gastric cancer. Certain strains of H. pylori may carry an increased risk of developing gastric cancer, but more research is needed to fully understand ...

Lost into space

Space physicists from the University of Leicester have identified a significant contributor to Mars' atmospheric escape: pressure from solar wind pulses. The team found that these pulses can drive away particles from Mars' atmosphere, causing a loss of about one third of the material lost into space.

Children with chronic respiratory illness are vulnerable to critical H1N1

A new study published in Pediatric Critical Care Medicine found that children with chronic illnesses are more likely to develop severe H1N1 infections. With careful management, pediatric ICUs can meet increased demands during a pandemic. Researchers also modeled PICU surge capacity and found it should be adequate with adaptable planning.

OHSU team discovers powerful molecule regulator in blood pressure control system

A research team at Oregon Health & Science University has discovered that nitric oxide is a powerful regulator of brain-derived neurotrophic factor (BDNF), a molecule involved in the development and function of the nervous system. This finding could play a significant role in preventing and treating high blood pressure.
