Drinking tea improves brain health, study suggests

A recent study led by researchers from the National University of Singapore (NUS) revealed that regular tea drinkers have better organised brain regions — and this is associated with healthy cognitive function — compared to non-tea drinkers. The research team made this discovery after examining neuroimaging data of 36 older…

Medical marijuana does not reduce opioid deaths

Legalizing medical marijuana does not reduce the rate of fatal opioid overdoses, according to researchers at the Stanford University School of Medicine. The finding contradicts a 2014 study that legal-pot advocates, public officials and even physicians have touted as a reason to legalize marijuana. That study found lower rates of…

Maternal microbes mediate diet-derived damage

New research in The Journal of Physiology has found, using a mouse model, that microbes in the maternal intestine may contribute to impairment of the gut barrier during pregnancy. Scientists previously thought the changes in maternal metabolism that happen during pregnancy were due entirely to pregnancy hormones. We now believe…

For its health and yours, keep the cat indoors

Pet cats allowed outdoors, in fact, are nearly three times as likely to become infected with pathogens or parasites than those confined to quarters, they reported in the Royal Society journal Biology Letters. At least one running argument among cat lovers is now over: Whiskers, Lucy and Tigger are definitely…

Parasitic worms cause cancer — and could help cure it

Billions worldwide are infected with tropical worms. Unsurprisingly, most of these people live in poor countries, kept poor by the effects of worm-related malnourishment. What may surprise many is that worms also cause the majority of cases of some cancers in these countries. Published in Frontiers in Medicine as a…

Scientists generate functional, transplantable B cells from mice

Functional B-1 cells derived from mouse embryonic stem cells are capable of long-term engraftment and secrete natural antibodies after transplantation in mice, researchers report February 7th in the journal Stem Cell Reports. Scientists are interested in B-1 cells generated from pluripotent stem cells because they could be tested as a…
