Waking up your Apple Watch to see "your heart has shown signs of an irregular rhythm suggestive of atrial fibrillation" might come as a shock. While your watch can send you warnings if it detects a fast or low heart rate, those messages are pretty vague, while the abnormal arrhythmia alert can downright scary. So what should you do if you receive one of these AFib notifications?
Your Apple Watch sends you notifications from friends, family, and the apps that are important to you. Occasionally, however, the watch may scare the heck out of you with a notification warning of an abnormal, elevated heart rate.

Bacteria, viruses and other germs sometimes set off the immune system to overreact, producing a severe condition called sepsis. Sepsis is so dangerous that it is the leading cause of death of children across the world, killing a million kids every year, mostly in developing countries. Probiotic bacteria might be able to prevent sepsis and infections, but no large research studies have been done to find out whether that actually works. Until now.
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.
Young girls, especially those who live in areas where HIV is epidemic, like sub-Saharan Africa, are particularly vulnerable to becoming infected with HIV. A vaginal ring containing the antiviral agent dapivirine has been shown to decrease the chance of developing HIV-1 in adult women over 21 and now in the first step for use in adolescents, the ring has been shown to be safe and well-tolerated in that younger age group.
Type 1 diabetes is an attack on the body by the immune system — the body produces antibodies that attack insulin-secreting cells in the pancreas. Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.

In the past, infection with human immunodeficiency virus (HIV) commonly led to dementia as the virus made its way to the brain. Even in effectively treated people, HIV can hide out and replicate in places like the brain, where it's tough to detect. That's why it's very concerning that half of all HIV-infected patients still report cognitive problems.
A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the drug-resistance process.
