Cancer and Heart Disease Could Be Contagious Through Our Microbiomes, Scientists Argue

It’s a science lesson you probably learned in grade school: You can only catch certain illnesses, like the flu, from another person. But a new paper argues that many diseases seen as noncommunicable, like most cancers and heart disease, might be transmissible sometimes – thanks to the seemingly harmless microbes living in and on our bodies.

Scientists Reconstruct ‘Lola’ After Finding Her DNA in 5,700-Year-Old ‘Chewing Gum’

Scientists in Denmark have squeaked out an entire human genome from a prehistoric piece of “chewing gum.” Made from birch tar, the 5,700-year-old gum also contained evidence of diet and disease and is providing a remarkable snapshot of life during the early Neolithic. Read More >>

Even the Flies Inside Hospitals Carry Antibiotic-Resistant Bacteria

Upwards of 90 per cent of insects found in British hospitals carry potentially harmful bacteria, according to new research. Alarmingly, a significant portion of this bacteria is resistant to one or more antibiotics, highlighting a previously under-appreciated health risk—though the researchers caution that chances of infection are low.

Sea Bacteria Colonise Your Skin After Just 10 Minutes of Swimming

If sharks and sunburns don’t scare you at the beach, perhaps this will: according to preliminary research out this week, it only takes a 10-minute swim in the sea to get your skin covered in a fresh coat of bacteria. While that’s not necessarily bad, some of these bacteria could be disease-causing or raise your risk of infection by disrupting your skin’s delicate microbial environment, known as the microbiome.

A Common Household Ingredient Might Sabotage Your Antibiotics

Your daily gob of toothpaste or spritz of body spray might be inadvertently mucking up your antibiotic treatment, suggests new research. It found that a common household antimicrobial ingredient—triclosan—seemed to reduce the potency of antibiotics used to treat urinary tract infections by a hundred-fold, at least in mice.

Ancient Black Plague Found in Swedish Gravesite

Long before the two deadliest pandemics in history—the Plague of Justinian and the Black Plague—an ancient strain of the bacterium responsible for these scourges, Yersinia pestis, may have already wreaked havoc among Neolithic European communities over 5,000 years ago, according to a controversial new study.

Probiotic Supplements Might Be Giving Some People ‘Brain Fog’

Given their current popularity, you might assume that probiotics—capsules containing a mix of “good” bacteria that are said to rebalance our gut’s bacterial content—would be perfectly harmless. But a team of gastroenterologists from Augusta University in the US state of Georgia is challenging that assumption. Their recent study is the latest to suggest some people who take probiotics can develop a strange collection of symptoms, including gas, diarrhoea, and “brain fog.” Read More >>
