Flu shot season is here. But as you head to the doctor’s office or pharmacy to get vaccinated, scientists are working to make this yearly ritual a thing of the past. Researchers around the world, including at the University of Rochester Medical Center (URMC), are pursuing a “universal” flu vaccine, one that would protect against most or all seasonal and pandemic strains of the flu virus.

Is it any wonder that most happiness idioms are associated with nature? Happy as a pig in muck, happy as a clam, happy camper.

Young hockey players who have suffered concussions may still show changes in the white matter of the brain months after being cleared to return to play, researchers at Western University have found through sophisticated Magnetic Resonance Imaging (MRI) techniques.

There is little debate over the link between air pollution and the human respiratory system: Research shows that dirty air can impair breathing and aggravate various lung diseases. Other potential effects are being investigated, too, as scientists examine connections between toxic air and obesity, diabetes and dementia.

Now add to that list psychological distress, which University of Washington researchers have found is also associated with air pollution. The higher the level of particulates in the air, the UW-led study showed, the greater the impact on mental health.

A new Tel Aviv University study solves a critical piece of the puzzle of human deafness by identifying the first group of long non-coding RNAs (lncRNAs) in the auditory system.

Mexican doctors have safely reused donated pacemakers after sterilisation, shows a study presented at the 30th Mexican Congress of Cardiology. The findings create the possibility for patients to receive a pacemaker who otherwise could not afford one.

Deep brain stimulation is a long-established surgical procedure that eases the effects of Parkinson’s disease and essential tremor through pulses from tiny electrodes implanted in the brain. Currently, most surgeons around the world conduct this surgery while the patient is awake.

When overweight adults exchange refined grain products – such as white bread and pasta – with whole grain varieties, they eat less, they lose weight and the amount of inflammation in their bodies decreases. These are some of the findings of a large Danish study headed by the National Food Institute, Technical University of Denmark. The study supports the scientific basis for the Danish dietary recommendation to choose whole grains.

Captain David Matschke is well aware of the dangers he faces on the job. A firefighter for 32 years, he is trained to race to the scene of house fires, car crashes and even industrial accidents, breaking through windows and doors to evacuate occupants and routinely putting himself in harm’s way. But beyond fire itself, a study published today in the journal Environmental Science & Technology sheds new light on another, more insidious threat that may be putting firefighters’ health at risk: toxic chemicals in smoke.

Much of Professor Emeritus Richard Wurtman’s career in MIT’s Department of Brain and Cognitive Sciences revolved around developing new treatments for diseases and conditions by modifying chemicals produced in the brain.
