A new experiment showed that humans may be able to reproduce in space, paving the way for self-sustaining colonies.

Knowing up and down seems key for sperm to reach an egg.

It’s just like coach used to say: practice makes perfect. Recent research suggests that regular masturbation and/or sex can ...

Sperm may lose their ability to navigate in microgravity, raising new questions about whether human reproduction is possible in space.

Among the many potential issues, life in space may wreck our kidneys, increase the risk for numerous diseases including ...

In 2022, Australian biotech startup Cortical Labs made a big splash after announcing that it had taught “mini-brains” consisting of 800,000 to one million living human brain cells in a petri dish how ...

As space agencies prepare for human missions to the Moon and Mars, scientists need to understand how the absence of gravity affects living cells. Now, a team of researchers has built a rugged, ...

With a so-called cryo plasma-FIB (Plasma Focused Ion Beam) scanning electron microscope with nanomanipulator, Goethe University in Frankfurt (Germany) is expanding its research infrastructure with a ...

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 ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore. The standard sperm-meets-egg story posits ...

But watching how the flu virus sneaks into cells has been difficult because standard microscopes can't capture these fast, tiny steps clearly. In a breakthrough study, scientists from Switzerland and ...

Scientists have identified a protein that may be key to proper sperm formation. Without it, male mice produced no viable sperm, they found. A team at the RIKEN Center for Biosystems Dynamics Research ...
