UT Knoxville professor finds unexpected key to flowering plants' diversity
What began with an off-the-cuff curiosity eventually led Joe Williams to hang from the limbs of a tree 80 feet above the soil of northeastern Australia. view more (2008-07-29)
Parachuting allows krill to eat and run
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts carbon in the process. view more (2006-02-07)
Use eggs, not embryos, to derive stem cells, say researchers
Concerns about the ethics of using embryos created to treat infertile couples for stem cell research is discussed by researchers at St Mary's Hospital, Manchester in this week's BMJ. Although the Human Fertilisation and Embryology Act 1990 allows the creation of embryos for research in the United Kingdom, the House of Lords Select Committee on... view more... (2003-10-08)
Publication of consultation document on donor anonymity and British Fertility Society's response
Anonymity of sperm and egg donors has been the subject of increasing debate over recent years. The Department of Health have sought the views of the public and professionals as to whether, and to what extent, information about people who have donated sperm, eggs or embryos should be given to children born as the result of those donations.1,2 The... view more...

A key to male fertility
Until now, mutations of the LH hormone receptor were the only explanation known for sexual precocity in boys. A team at the Institute of Genetics and Molecular and Cellular Biology (IGBMC, CNRS / Inserm / Université Louis Pasteur de Strasbourg)), in collaboration with researchers at the University of Dallas and the University of Louvain, has... view more...

New technique could save cancer patients' fertility
The tiny translucent egg nestled in the special laboratory gel was a mere 30 days old, but its four-week birthday caused researchers to quietly celebrate. view more (2009-07-14)
New method of assessing women's eggs could enhance IVF success, Stanford study shows
Many couples who have trouble conceiving a child have turned to a process known as in vitro fertilization. The resulting embryos are then transferred back into the woman or placed in storage. view more (2009-03-24)
New theory -- universal intelligence on animals and plants
Here it is proposed that life in all its variety is full of sensation and creates a complicated web of interaction with its surroundings. Mammals, birds and even fish mourn for a lost love. Single-celled organisms carry out tasks that are surprisingly complicated. We can demonstrate sensitivity in microscopic organisms, while plants emerge as... view more... (1999-03-25)
Truly informed consent must include talking about future fertility, warn experts
Talking about sex and fertility can be just as embarrassing for medical staff as for adolescent cancer patients, the 4th International Conference on Teenage and Young Adult Cancer Medicine heard today. view more (2006-03-30)
The tapeworm contraceptive
A tapeworm may be the unlikely source of a new contraceptive - 100% effective in either sex! Despite intensive research, scientists have so far failed to find the perfect contraceptive for women - let alone men. However, a study in freshwater fish of the carp family has found a parasite, Ligula intestinalis, that makes the fish infertile. The... view more... (2002-12-04)
Earth's Most Diverse Marine Life Found Off Indonesia's Papua Province
Two recent expeditions led by Conservation International (CI) to the heart of Asia's "Coral Triangle" discovered dozens of new species of marine life including epaulette sharks, "flasher" wrasse and reef-building coral, confirming the region as the Earth's richest seascape. view more (2006-09-21)
Leading scientists rank endangered dolphins, porpoises most in need of immediate action
Leading marine scientists for the first time have assessed dolphin and porpoise populations around the world which are severely threatened by entanglement in fishing gear and recommended nine urgent priorities for action in a report commissioned by the World Wildlife Fund. These nine projects highlight species threatened by bycatch that will most... view more... (2005-06-09)
Study hints at role of stem cell genes in testicular, breast cancers
UCSF scientists have discovered that the activity of several embryonic stem cell genes is elevated in testicular and breast cancers, providing some of the first molecular evidence of a link between embryonic stem cells and cancer. view more (2005-11-30)
Vasectomy may put men at risk for type of dementia
Northwestern University researchers have discovered men with an unusual form of dementia have a higher rate of vasectomy than men the same age who are cognitively normal. view more (2007-02-13)

Children of older fathers perform less well in intelligence tests during infancy
Children of older fathers perform less well in a range of cognitive tests during infancy and early childhood, according to a study published this week in the open-access journal PLoS Medicine. In contrast, the study finds that children with older mothers gain higher scores in the same tests - designed to measure the ability to think and reason,... view more... (2009-03-09)
New hope for regenerative medicine
In the February 15th issue of G&D, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. view more (2007-02-15)
Secrets in a seed: Clues into the evolution of the first flowers
Approximately 120-130 million years ago, one of the most significant events in the history of the Earth occurred: the first flowering plants, or angiosperms, arose. view more (2009-09-15)
Chemical Cudgel in Plants
Defense mechanisms of single-celled algae Plankton are at the bottom of the food chain in all natural bodies of water and are thus correspondingly important for their ecological balance. In the cycle of eating and being eaten it isn't only fish and whales that prey on these tiny animals and plants - they also eat each other. For example, a variety... view more... (2000-11-29)
Teenage fathers are more likely to have babies affected by birth problems
Teenage fathers are at increased risk of having babies born with birth problems ranging from pre-term delivery or low birth weight, through to death in or near to the time of delivery. view more (2008-02-07)
