Egg cells missing a key protein may be more likely to end up with the wrong number of chromosomes, but an mRNA injection that helps the cells make the protein reduces the problem

Two studies of Neandertal remains suggest their newborns were about the same size as those of modern humans but developed faster through infancy.

Fossils of Spriggina floundersi provide the earliest evidence of animals favouring one side of the body over the other – a feature of nervous systems that we see in our own right- and left-handedness
As summers in the UK get hotter, is it time for air conditioning to become a permanent feature in most homes?

Två personer med samma BMI kan ha helt olika risk att utveckla typ 2-diabetes, beroende på vilka biologiska mekanismer som ligger bakom deras vikt. Vissa typer av övervikt ökar risken för diabetes, medan andra inte påverkar risken alls, eller till och med verkar skydda mot sjukdomen. I en ny studie beskriver forskare de olika molekylära processer som driver dessa skillnader.

<p>Men’s average testosterone levels have halved over the past 50 years, according to scientists who say society is facing a male fertility crisis. Rising levels of obesity and diabetes are expected to play a part, but the team behind the work suggest that environmental factors such as endocrine-disrupting chemicals – which can be found in various household items – and global heating could also be factors in the apparent striking decline. Ian Sample speaks to science correspondent Hannah Devlin to find out how the work has been received and what the researchers want to see happen in response to their finding</p><p><strong><a href="https://www.theguardian.com/society/2026/jul/07/mens-average-testosterone-levels-have-halved-in-last-50-years-say-scientists">Men’s average testosterone levels have halved in last 50 years, say scientists</a></strong></p><p>Support the Guardian: <a href="http://theguardian.com/sciencepod">theguardian.com/sciencepod</a></p> <a href="https://www.theguardian.com/science/audio/2026/jul/09/is-male-testosterone-in-freefall-podcast">Continue reading...</a>
