State-level cannabis legalization in the U.S. is producing a lot of innovative ways to get high, but little in the way of evidence-based medical research to improve public health, according to new research from economists at the University of Massachusetts Amherst.

An anterior cruciate ligament injury is a serious knee injury that often affects young, physically active people. On April 30, Dzan Rizvanovic will defend his thesis "Anterior cruciate ligament reconstruction: rationale for graft choice and treatment of associated injuries" in which he has investigated how treatment choice affects outcomes after ACL reconstruction.

The U.S. Food and Drug Administration (FDA) has issued a Class I recall for Nuts.com's Espresso Malted Milk Balls after finding the product contains undeclared wheat and soy, two major allergens.

Every year in the U.S., about a million people are treated at emergency rooms for traumatic brain injuries (TBIs), and about 50,000 people die from the injuries or complicating factors, according to the International Brain Injury Association. Mild TBIs such as concussions can result from a hit to the head, a fall, car accident, or sports collision. Patients often experience nausea, sleep disturbances, or confusion in mild cases. However, patients with more severe TBI can lose consciousness, have memory loss, or die from the injury.

When health risks become visible in black and white, perspectives often shift. A study from Umeå University shows that when ultrasound images of atherosclerosis in subjects' carotid arteries are combined with a motivational dialogue, the patients are more likely to be motivated to improve their lifestyle habits and take preventive medication.

Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ribosomes—protein-building machines in our body. It helps build proteins by linking amino acids together, and can also fine-tune this process by interacting with other proteins and messenger RNA (mRNA). For a long time, scientists assumed ribosomes were more or less identical within a species. A new study in Cell Genomics is challenging that idea.

Food calorie labels on menus in cafes and restaurants can be helpful for people with binge eating disorders, even aiding their recovery, finds new research from UCL and King's College London. For the study, published in BMJ Public Health, the researchers surveyed 1,001 people aged 16 or over who lived in England and had experienced disordered eating. Since 2022, all restaurants, take-aways and cafes in England with 250 employees or more have had to display the calories of the food and drink they sell on menus, online menus and take-away platforms as part of measures to curb obesity and encourage healthy eating.

Older Chinese immigrants living in neighborhoods with greater access to community amenities, services, and supportive infrastructure experienced slower cognitive decline over time, according to Rutgers Health researchers.

Mice make use of rapid nerve cell interactions in the brain's smell center to distinguish one odor from another, a new study shows. Both mice and humans can rapidly identify odors, researchers say, in a small fraction of a second. Led by researchers at NYU Langone Health, the study shows that the key steps involved in identifying smells happen in the mouse olfactory bulb, a part of the brain located behind the nose. The function was previously thought to occur in the cerebral cortex, a larger part of the brain known for its role in perception, awareness, and thought.

A substantial amount of medical information provided by five popular chatbots is inaccurate and incomplete, with half (50%) of the responses problematic: 30% were somewhat, and 20% were highly problematic. These are the results of a study published in the journal BMJ Open.
