An experiment to study the effects of naturally deposited iron in the Southern Ocean has filled in a key piece of the puzzle surrounding iron’s role in locking atmospheric carbon dioxide (CO2) in the ocean.

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

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.

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.

Polar body diagnosis can make artificial fertilization more successful, according to Katrin and Hans van der Ven and Markus Montag of Bonn University Clinic, writing in the current edition of Deutsches Дrzteblatt International (Dtsch Arztebl Int 2008; 105[11]: 190-6).

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.

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 at the University of California, San Diego have discovered a gene in plants that disrupts fertilization only when mutations in the gene are present in both the female and male reproductive cells.

Scientists at Punjab Agricultural University, the International Rice Research Institute, and Virginia Tech have been successful in increasing average rice yields in northwest India using site-specific nutrient management strategies.

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.

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.

Most of us have never heard of immune infertility, yet it prevents many prospective parents from conceiving.
