Mathematical model can improve our knowledge on cancer

Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a new mathematical tool to characterize what happens when cells lose their polarity (direction) in diseases such as cancer. The result is advancing ...

How do jumping genes cause disease, drive evolution?

Almost half of our DNA sequences are made up of jumping genes—also known as transposons. They jump around the genome in developing sperm and egg cells and are important to evolution. But their mobilization can also cause ...

Elegant switch controls translation in transition from egg to embryo

The transition from an egg to a developing embryo is one of life's most remarkable transformations. Yet little is known about it. Now Whitehead Institute researchers have deciphered how one aspect—control of the all-important ...

In roundworms, fats tip the scales of fertility

Proper nutrition can unleash amazing powers, moms have always assured us, frequently citing Popeye the Sailor Man as evidence. Now, two University of Colorado Boulder scientists have confirmed just how potent some nutrients ...

For the perfect eggs, roundworms use small RNAs

All multicellular organisms that reproduce sexually rely on eggs to support early life. Researchers at University of California, San Diego School of Medicine and Ludwig Cancer Research used the tiny roundworm C. elegans as ...
