Study reveals how the ovarian reserve is established

Fertility is finite for mammalian females. From birth, females possess a limited number of primordial follicles, collectively called the ovarian reserve. Within each follicle is an oocyte that eventually becomes an egg. But ...

How environmental microbes boost fruit fly reproduction

For many of us, when we think of microbiomes, our first thoughts are probably about the beneficial microorganisms that live in our guts. But now, researchers from Japan and the US have discovered how the microbes living in ...

Researchers compile world's first 'atlas' of airborne microbes

Bacteria are truly abundant across the Earth's surface, from the soil to the oceans. The microbial population of the air that surrounds us is comparatively unknown, but a research expedition led by PolyU scientists is about ...

Science and adventure on first leg of ocean expedition

Scientists undertaking a UNSW-led expedition to study microbes in the Indian Ocean have weathered huge seas and had a close encounter with giant whales during the first leg of their voyage from South Africa to Mauritius.

Protecting biocatalysts from oxygen

Certain enzymes from bacteria and algae can produce molecular hydrogen from protons and electrons—an energy carrier on which many hopes are riding. All they need for this purpose is light energy. The major obstacle to their ...
