New research which shows that taking the stairs could help you live longer.

A major new study reveals that climbing the stairs significantly reduces the risk of dying from cardiovascular disease.

Over the course of the study, people who regularly climb stairs were 39 per cent less likely to die from heart-related problems and 24 per cent less likely to die from any cause - compared with people who don't climb stairs as often.

The study also reveals that people who climbed the stairs were less likely to suffer major cardiovascular conditions such as a heart attack, stroke and heart failure.

Being an elite athlete, at least as a mouse, does not shorten lifespan or limit how many children you can have. This is the finding of a study 30 years in the making, and it runs counter to accepted evolutionary theory. 

Scorching heat waves, severe cold snaps, and other extreme weather events are limiting where species can exist — and affecting biodiversity estimates — for more than 500 North American bird species, according to a new, Yale-led study. 

The issue is particularly acute in the Great Plains and southwestern regions of the United States, where species ranges and total species counts are significantly overestimated when variable and extreme weather are not considered, the study says. 

The findings were published in the journal Global Change Biology. 

“We all know extreme weather is on the rise with climate change,” said Jeremy Cohen, the study’s lead author. He is an associate research scientist in Yale’s Department of Ecology & Evolutionary Biology, a member of the lab of co-author and Yale professor Walter Jetz, and part of the Yale Center for Biodiversity and Global Change. “This is the first study to look at how increasingly variable and extreme weather affects avian biodiversity at a continental scale.”

An analysis of Reddit posts about the maternal Tdap vaccine made by pregnant women reveals expectant mothers turning to Reddit to seek advice and reassurance—with fewer outright instances of vaccine hesitation/refusal than has generally been observed for other types of vaccines, according to a study published on August 12, 2026 in the open access journal PLOS Global Public Health by Soojung Jo from Purdue University, United States, and colleagues.
