Human gut microbes could make processed foods healthier
A new study sheds light on how human gut microbes break down processed foods — especially potentially harmful chemical changes often produced during modern food manufacturing processes.
Read moreAntibiotic resistance in food animals nearly tripled since 2000
Researchers report that the growing appetite for animal protein in low- to middle-income countries has resulted in a smorgasbord of antibiotic consumption for livestock that has nearly tripled the occurrence of antibiotic resistance in disease-causing bacteria between 2000 and 2018. The researchers found that antibiotic resistance in livestock was most widespread in China and India, with Brazil and Kenya emerging as new hotspots.

An international team of researchers identifies the genetic basis for the hypervirulence of a Listeria strain that can cause severe infections.
Read moreResearchers use game theory to successfully identify bacterial antibiotic resistance
Researchers have developed a novel way to identify previously unrecognized antibiotic-resistance genes in bacteria.

The potential impact of undiagnosed sexually transmitted chlamydia infection on men's fertility has been highlighted in a study, which for the first time found chlamydia in the testicular tissue biopsies of infertile men whose infertility had no identified cause.
Read moreWorrisome badger behavior inside the cull zone
A new study has found that culling drives badgers to roam 61% further afield — helping to explain why the practice, intended to reduce bovine TB transmission, can sometimes exacerbate the problem instead.
Read moreWhy we crave junk food after a sleepless night
When you're sleep deprived, you reach for doughnuts and pizza. A new study has figured out why you crave more calorie-dense, high-fat foods after a sleepless night. Blame it on your sleepy nose — or olfactory system. First, it goes into hyperdrive, sharpening the food odors for the brain. But then there is a breakdown in communication with brain areas that receive food signals. Then decisions about what to eat change.
Read moreNew study is 'chilling commentary' on future of antibiotics
The health care market is failing to support new antibiotics used to treat some of the world's most dangerous, drug-resistant 'superbugs,' according to a new analysis.

Chemists transform their laser-induced graphene into an air filter that not only traps pathogens but also kills them with a small blast of electricity.
