VIDEO: New York Times science reporter Apoorva Mandavilli chronicles the rise of the delta variant, the latest of many twists in the pandemic that she’s covered since it began. Delta has left parents in an especially tough spot, with schools opening but young children still vulnerable.
Eliminating this food-poisoning bacterium from poultry is tricky — not least because rapid, precise tests are still unavailable. Researchers are looking at vaccines, probiotics, prebiotics and even essential oils as ways to reduce contamination on the farm.
Some children have been hospitalized and some have died, but at a tiny fraction of the adult rate. As children head back to school, scientists are hoping that research will provide answers.
Polypharmacy — taking five or more meds at a time — leads to side effects, unnecessary hospitalizations and premature deaths. Researchers and pharmacists are seeking solutions to this serious public health problem that disproportionately affects older adults.
VIDEO: Wearable devices are increasingly used for tracking health data and identifying problems. Learn from health researchers about exploring the promise and pitfalls of personal tech.
VIDEO: Scientists expected the novel coronavirus would mutate and change. But its runaway spread means new, more dangerous variants are more likely to emerge. Harvard computational geneticist Pardis Sabeti explains.
As Covid-19 descended across the world, people sought refuge in gardens, parks and the woods. But it’s hard to measure how being in nature affects our well-being — and how we can best reap its rewards.
OPINION: A neuroscientist says that he’s particularly worried about kids, who may have spent much of last year learning online. Some easy hacks can help.
Hesitancy rates are falling but they’re still sizable, especially among certain groups. Easy access and trusted community messengers are keys to moving the needle.
Covid-19 has been a stress test for the world’s food supply chains — and a preview of looming threats. That’s making efforts to improve the journey from farm to fork more urgent than ever.
The Covid-19 lockdown has changed alcohol habits, but public health researchers face a blurred and incoherent picture of who’s been drinking, and how much
