In this week’s issue of Science, a team of researchers from the United States and Sweden report on a newly identified factor that controls the natural input of new nitrogen into boreal forest ...

Scientists have discovered a new protein which helps sperm fuse to an egg and is fundamental for human fertilization. The new protein, named MAIA after the Greek goddess of motherhood, could be ...

Researchers at ETH Zurich recently developed highly realistic simulations of the proteins on sperm and egg cells coupling together before they fuse. These findings enabled the research team to solve ...

Infertility is a challenge that many couples face and it can affect both men and women. There are various reasons for ...

Nitrogen is the primary nutrient that dictates productivity (and thus carbon consumption) in boreal forests. In pristine boreal ecosystems, most new nitrogen enters the forest through cyanobacteria ...
