Collaboration between Leicester and South Korean scientists explains plants' 'double fertilization' process

Scientists announce mouse sperm cryopreservation breakthrough

A team of Jackson Laboratory scientists have figured out a simple, cost-effective process to freeze mouse sperm and get it to achieve high fertilization rates with mouse eggs. The breakthrough will greatly reduce the cost of developing and distributing new mouse models of human disease.

Forest canopies help determine natural fertilization rates

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 ecosystems. Nitrogen is the primary nutrient that dictates productivity (and thus carbon consumption) in boreal forests.

Genetic test improves artificial fertilization

International investigations of an organism that one UT Southwestern Medical Center researcher calls a “silly little green scum” have led to key insights into the basic mechanisms of reproduction.

Evolutionary phenomenon in mice may explain human infertility

Scientists at the University of Liverpool have found that field mice have evolved a unique way of ensuring faster fertilisation, a phenomenon which could explain some cases of infertility in humans.

Biologists find unusual plant gene

Scientists have revealed an important discovery that raises doubts concerning the viability of plans to fertilize the ocean to solve global warming, a projected $100 billion venture.

In birds, expecting to mate leads to higher fertilization rates

harminka — Fri, 05 Oct 2007 05:09:53 -0500

From an evolutionary perspective, the primary task of an organism is to pass along its genes to future generations. Such genetic transmission is usually assumed to be instinctive.

Researchers find important clue to immune infertility
