The cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins jiggling against one another and drifting at random. Yet a new biophysical study finds that those drifting objects…

Hematopoietic stem cells (HSCs) are adult stem cells isolated from blood or bone marrow that can renew themselves and differentiate into a variety of specialized cells. They give rise to all other…

Scientists have identified a gene, Lhx1, that regulates sleep and wake rhythms. The discovery of the role Lhx1 provides scientists with a potential therapeutic target to help night-shift workers or…

Not that you want to do this but there is an easy way to speed up a woman's reproductive timing - just get a clock. Not one of those modern digital things, an actual ticking clock will literally do…

Researchers have create a molecule that can cause cancer cells to self-destruct by carrying sodium and chloride ions into the cells. Synthetic ion transporters have been created before, but this is…

The Mediterranean fruit fly is a serious agricultural pest, it infests more than 300 types of cultivated and wild fruits, vegetables and nuts and causes extreme damage to crops all around the…

Scientists have sequenced the genome of Belgica antarctica, the Antarctic midge – the smallest in insects described to-date –  and believe it can explained by the midge's adaptation to its deep-…

Researchers have come up with a promising method of treating male infertility; a synthetic version of the sperm-originated protein known as PAWP. PAWP has been shown to be required, they write, and…

Hey, heads up Public: game-changing new science means we can probably make insects stop spreading malaria, dengue fever, and Lyme disease.  Or reverse pesticide resistance in agricultural pests…

Spider silk is lightweight and stretchy yet has tensile strength greater than steel. Its chemistry is just as fascinating. Silk proteins, called spidroins, must convert from a soluble form to…
