Mars model provides method for landing humans on Red Planet

A mathematical model developed by space medicine experts from The Australian National University (ANU) could be used to predict whether an astronaut can safely travel to Mars and fulfil their mission duties upon stepping ...

Getting the fossil record right on human evolution

Uncovering the evolution of any set of living creatures is a complex and highly detailed task for scientists, and theories and approaches that may differ over time may indeed change the fossil record. But paleoanthropologist ...

The secret to longevity? Ask a yellow-bellied marmot

That's what a team of UCLA biologists and colleagues studying yellow-bellied marmots discovered. These large ground squirrels are able to virtually halt the aging process during the seven to eight months they spend hibernating ...

Researchers devise sex-cell precursors with staying power

Human primordial germ cells (PGCs) are the early precursors of the eggs (oocytes) and sperm that are necessary to keep humankind alive and reproducing. Medical researchers attempt to study their function and development using ...

More predictive in vitro assays may improve nanomedicine

Messenger RNA (mRNA) vaccines are a prime example of the promising field of nanomedicine. But progress in the design and application of nanoparticles as efficient delivery vehicles for biopharmaceutics containing nucleic ...
