Ecologists have, for the first time, teased out the many interacting factors that explain why species diversity and productivity vary so greatly between different grassland ecosystems across the globe.
Sperm that don't swim well rank high among the main causes of infertility. To give these cells a boost, women trying to conceive can turn to artificial insemination or other assisted reproduction techniques, but success can ...
Christmas seems an appropriate time to ask whether it's biologically possible to have a virgin birth. And you may be surprised to hear that it is possible – just not for humans, or any other mammals.

Urine could be successfully recycled to fertilise crops according to University of Sydney civil engineering researchers who have examined the effectiveness of reusing nutrients from the human waste.
Researchers have developed new methods to trace the life history of individual cells back to their origins in the fertilised egg. By looking at the copy of the human genome present in healthy cells, they were able to build ...
