Men assess potential rivals that have a larger penis as more of a threat, both physically and sexually, according to a study by Upama Aich at the University of Western Australia and colleagues, ...

Scientists first read the human genome, a three-billion-letter biological book, in April 2003. Since then, researchers have steadily advanced the ability to write DNA, moving far beyond single-gene ...

A new study tests whether spent yeast from breweries can supply cellulose scaffolds that support lab-grown meat production.

Weighing a single living cell sounds like a party trick, yet the numbers involved are so small that they push the limits of physics and engineering. To make sense of a weight like 3.5e-14 ounces, I ...

How much of our genome really matters? Some argue that because most of our DNA is active, it must be doing something important. Others say even random DNA would be highly active. This has now been put ...

What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis ...

Why cells grow to just the right size has long baffled scientists. Too small or too large, and cells can trigger serious diseases, but the genetic switch behind this balance has remained elusive. Now, ...

"The infection of our body cells is like a dance between virus and cell," suggested Yohei Yamauchi at ETH Zurich. With their new system, the team watched how single flu virus particles move across the ...
