Food memories can help with weight loss

A study published in the American Journal of Clinical Nutrition found that recalling recent meals reduces food consumption, while being distracted during eating leads to increased intake. Techniques such as writing down previous meals and using visual reminders can aid in reducing meal sizes.

BU School of Medicine launches safe opioid prescribing education program for health care providers

The Boston University School of Medicine has launched a safe opioid prescribing education program, funded by the first of its kind $1.8 million grant from manufacturers of extended release/long-acting opioid analgesics. The program is designed to train healthcare providers on how to safely manage patients with chronic pain using opioids.

More hurricane surges in the future

New research from the Niels Bohr Institute predicts a tenfold increase in extreme storm surges due to global warming, resulting in 'Katrina' magnitude storms every other year. The study suggests that 0.4 degrees Celcius warming already leads to a doubling of extreme storm surges and an additional 3-4 times increase with further warming.

Does Greek coffee hold the key to a longer life?

Researchers found that boiled Greek coffee consumption was associated with improved endothelial function and reduced blood pressure, even in those with high blood pressure. The study suggests that the polyphenols and antioxidants in this type of coffee may be beneficial for cardiovascular health.

Tourist-fed stingrays change their ways

Researchers found that tourist-fed stingrays at Stingray City show distinct patterns of activity, including daytime feeding and nighttime resting, compared to wild stingrays. Human interaction has drastically altered their behavior, with some stingrays abandoning their solitary nature and forming schools.

Causing collapse

Weizmann Institute researchers found that measuring a single atom's spin can collapse its superposition into one state. By adjusting the polarization of the emitted photon, they demonstrate that observers can influence the spin collapse, suggesting an 'action-at-a-distance' effect.

Cell on a chip reveals protein behavior

Researchers at the Weizmann Institute of Science created a two-dimensional cell-like system on a glass chip, enabling precise observation of gene expression and protein behavior. The system allows for the simultaneous production and trapping of multiple proteins, revealing a spectrum of protein activities.

Training program developed by U of A medical researchers leads to police using less force

A one-day training program designed by U of A medical researchers led to officers being more likely to recognize mental health issues during calls and less likely to use physical force. The training resulted in long-term behaviour change and saved the police force $80,000 due to increased efficiency.

When it rains these days, does it pour?

Researchers analyzed over 70 years of hourly precipitation data from 13 US sites to test the hypothesis that storms are becoming more frequent and intense as the climate warms. They found a significant steady increase in stormy activity on the Olympic Peninsula in Washington State, which is famously prone to drizzle.

Researchers found that mycolactone, a lipid toxin from Mycobacterium ulcerans, causes cytoskeletal dysregulation by activating the protein N-WASP. This led to defects in cell adhesion and migration, impairing skin integrity. The study suggests using N-WASP inhibitors as potential treatments for Buruli ulcers.

Unhealthy eating can make a bad mood worse

Researchers discover that unhealthy eating behaviors can worsen moods in women without prior mood changes, leading to a better understanding of the relationship between emotions and eating. The study's findings suggest that this connection may play a role in the development and maintenance of unhealthy eating habits.

Cytoskeletal dysregulation underlies Buruli ulcer formation

Researchers discovered that mycolactone, a lipid toxin produced by Mycobacterium ulcerans, disrupts the cellular skeleton through N-WASP activation. This dysregulation impairs skin integrity and cell adhesion, leading to Buruli ulcers. Blocking N-WASP activity with wiskostatin may provide a new treatment approach.
