Researchers are investigating medicines that selectively kill decrepit cells to promote healthy aging — but more work is needed before declaring them a fountain of youth
From building up defenses in the nose to slowing down a virus’s ability to make copies of itself, scientists are rolling out a raft of creative approaches to fighting infection
The rhythm of respiration influences a wide range of behaviors, as well as cognition and emotion. Neuroscientists are piecing together how it all works.
Because of their height, giraffes require scarily high blood pressures — yet they escape the massive health problems that plague people with hypertension. Can clinicians learn from these animals?
A gaggle of biotech start-ups are trying vastly different approaches to spin animal studies into the next big anti-aging therapy. It’s too early to know which, if any, will succeed.
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.
VIDEO: Watch a scientific exploration of why old age is often associated with high levels of emotional well-being, even as physiological and cognitive capacity declines
VIDEO: Watch our conversation about how infectious agents are transmitted from one species to another, and what can be done to prevent future pandemics
Itching has myriad causes and mechanisms, many of which remain elusive. Scientists are making headway on parsing its biological underpinnings, in hope of better treatments.
Researchers helped mice stay mighty with an experiment to counter the effects of microgravity. The gene treatment might also enhance muscle and bone health on Earth — and in humans.
New blood assays and brain scans are among the biomarkers revolutionizing clinical trials and changing the way researchers think of the disease. They may soon change the way patients are treated as well.
Pathogens that switch to a new host species have some adapting to do. How does that affect the course of a pandemic like Covid-19?
