Studies show marine reserves can be an effective tool for managing fisheries
A recent study in the Gulf of California, for example, confirmed the validity of a key concept behind marine reserves--the idea that offspring produced in a protected area can replenish the stocks of ...

Researchers at the school have devised a way to efficiently coax the cells to become human germ cells — the precursors of egg and sperm cells — in the laboratory. Unlike previous research, which yield...
Life Sciences | Read moreStanford researchers' magnetic nanotags spot cancer in mice earlier than current methods
Searching for biomarkers that can warn of diseases such as cancer while they are still in their earliest stage is likely to become far easier thanks to an innovative biosensor chip developed by Stanfo...

There are approximately 40,000 species of spiders in the world, all of which have been thought to be strict predators that feed on insects or other animals. Now, scientists have found that a small Cen...
Life Sciences | Read moreRatchet-like genetic mutations make evolution irreversible
A University of Oregon research team has found that evolution can never go backwards, because the paths to the genes once present in our ancestors are forever blocked. The findings -- the result of th...

Collaborating teams from the University of York in the UK and the University of Calgary in Canada combined their expertise in molecular genetics and computational modelling to make a significant disco...
Life Sciences | Read moreConflict between plant and animal hormones in the insect gut?
A reaction similar to the inactivation of prostaglandin hormones in animals has now been discovered in the larval guts of two plant pest species. The insects bear an enzyme which structurally modifies...
Life Sciences | Read moreDramatic biological responses to global warming in the Arctic
The team's research documents a wide range of responses by plants, birds, animals, insects, and humans to the warming trend. The scientists found that the increase in mean annual surface temperat...
