UC San Diego researchers have developed an artificial intelligence system to quickly and accurately screen patients with potentially blinding retinal diseases to see if urgent treatment is needed. The system used machine learning to identify macular degeneration and diabetic macular edema within 30 seconds with more than 95 percent accuracy, said Kang Zhang, MD, a professor of ophthalmology at UCSD’s Shiley Eye Institute.

Don’t Panic, but Researchers Have Discovered That Stress is Contagious

Don't Panic, but Researchers Have Discovered That Stress is Contagious

Researchers have discovered brain cells change following close contact with a stressed individual. Simply put, stress is contagious. Stress can be brought on by big things like existential crises. More commonly, stress comes from trivial, every-day things like walking into a meeting that’s already started. Living in a world dominated by social media, we are constantly forced to compare our lives to those of others. Life is, by nature, unstable and uncertain, which can make stress inevitable. Therefore, it is unsurprising that we find ourselves in the midst of an anxiety epidemic.

Up to 60 per cent of prisoners have head injuries, as experts warn brain damage may fuel crime 

More than half of criminals may have suffered a head injury which could be fuelling their offending, a new review by British brain experts suggests. Specialists from the universities of Oxford, Exeter, Manchester, Glasgow and Sheffield, and the Centre for Mental Health, are calling for all prisoners to be routinely checked for signs of traumatic brain injuries.

Adverse cardiovascular effects of noise in humans.

Adverse cardiovascular effects of noise in humans.

Noise has been found associated with annoyance, stress, sleep disturbance, and impaired cognitive performance. Furthermore, epidemiological studies have found that environmental noise is associated with an increased incidence of arterial hypertension, myocardial infarction, heart failure, and stroke. There is now plenty of evidence that noise makes you sick. After carrying out a review of previous studies, they concluded that noise induces a stress response through the sympathetic nervous system, the system which activates the so-called fight or flight response. In turn, this increases hormone levels.
