Humans’ sense of smell may indeed be gradually fading, according to a study that has found people carry different versions of two scent receptors for musk and body odor. Olfactory receptors detect airborne chemicals that waft into our noses, but smell receptors vary immensely from one person to the next. Any two people, on … Read more

The pathway to humans on Mars lies through the atom, split. Far from Earth, whether in the void or on another world, power is life. A steady, strong flow of electricity is as crucial for operating computers and engines as it is for assuring access to corporeal necessities such as light and heat, breathable air … Read more
When it comes to killing and eating other creatures, chimpanzees—our closest relatives—have nothing on us. Animal flesh makes up much more of the average human’s diet than a chimp’s. Many scientists have long suggested our blood lust ramped up about 2 million years ago, based on the number of butchery marks found at ancient archaeological … Read more

About a million years ago a small mutation might have unlocked a big advantage for ancient humans. A recent study in Science Advances suggests that a variant of a critical stretch of DNA called the growth hormone receptor gene protected against starvation—in part by limiting individuals’ body size during periods of resource scarcity. The variant … Read more
Researchers have discovered a protective gene variant that seems to shield people from severe cases of COVID-19, and the finding could lead to new breakthroughs in fighting the coronavirus. Since much earlier in the pandemic, scientists have been busily investigating how patient genetics influence the severity of a SARS-CoV-2 infection, exposing the inherited factors … Read more
