Fossilised Embryos - 500 Million Years Old
Evidence from fossilised embryos of worm-like creatures that lived 500 million years ago shows that embryos developed then in much the same way as their living relatives do today. The implications of this remarkable discovery, reported in this week's issue of Nature, is that embryological processes that occur today must have been established very... view more... (2004-01-12)
Not so brief lives: The danger of underestimating how long we will live
People retiring in the next decade or so will live considerably healthier, more active and longer lives than their predecessors. But according to research by James Banks and colleagues, many are drastically underestimating the chances of their retirement lasting at least 10 years - and hence may not be saving 'enough'. The first results of Banks... view more... (2004-06-18)
Where's the beef? Not enough of it is on elders' plates, muscle-metabolism study suggests
Scientists at the University of Texas Medical Branch at Galveston have good news for people who want to stay strong in their old age: older bodies are just as good as young ones at turning protein-rich food into muscle. view more (2007-08-09)
Hippo ancestry disputed
Hippos spend lots of time in the water and now it turns out (or researchers argue), they are the closest living relative to whales. It also turns out, the two are swimming in a bit of controversy. view more (2009-03-19)
Study shows false memories complicate end-of-life treatment decisions
Advance directives, or living wills, may not effectively honor end-of-life wishes because life-sustaining treatment preferences often change over time without people being aware of the changes, according to a new study co-authored by UC Irvine researchers Peter Ditto and Elizabeth Loftus. view more (2008-04-28)
Scientists get first look at nanotubes inside living animals
Rice University scientists have captured the first optical images of carbon nanotubes inside a living organism. Using fruit flies, the researchers confirmed that a technique developed at Rice -- near-infrared fluorescent imaging -- was capable of detecting DNA-sized nanotubes inside living fruit flies. view more (2007-09-25)
Single thawed embryo transfer after PGD does not affect pregnancy rates
Transferring just one embryo at a time to a woman's womb after embryos have undergone preimplantation genetic diagnosis (PGD) and freezing at the blastocyst stage has become a real option after researchers achieved pregnancy rates that were as good as those for blastocysts that had not had a cell removed for PGD before freezing. view more (2009-06-30)
ICSI and IVF are safe - results from world's largest, longest running study
Madrid, Spain: The world's largest and longest running study comparing children conceived through IVF and ICSI[1] with children conceived normally has confirmed that both assisted reproductive techniques are safe and that children conceived through these two techniques are healthy and, in general, doing as well as children conceived by natural... view more...

UCR Researchers Grow Bone Cells on Carbon Nanotubes
Researchers at the University of California, Riverside have published findings that show, for the first time, that bone cells can grow and proliferate on a scaffold of carbon nanotubes. view more (2006-03-16)
Field Museum provides gold standard for mammal survey
Putting together the Who's Who of bats, bears, beaked whales and all of Earth's other known mammals was a gigantic task ably assisted by a Field Museum scientific team with access to one of the planet's most extensive and diverse mammal collections. view more (2008-10-07)
Using carbon nanotubes to seek and destroy anthrax toxin and other harmful proteins
Researchers at Rensselaer Polytechnic Institute have developed a new way to seek out specific proteins, including dangerous proteins such as anthrax toxin, and render them harmless using nothing but light. view more (2007-12-11)
Women living in group homes need to learn to make decisions about leisure time to enrich their lives
Most people don't think twice about the ability to choose the movie they want to watch, the book they want to read or with whom they will have coffee. view more (2009-09-24)
New perspective on brain function now possible
A newly started research collaboration between Karolinska Institutet and AstraZeneca has already generated results. For the first time, the conditions have been created to study one of the brain's most important neurotransmission systems - the glutamate system - in living people. view more (2007-05-30)
Diabetics with previous foot ulcers may be able to participate in walking program
More than 20 million Americans are living with diabetes, and that number is expected to increase by more than 5 million by 2010. view more (2009-01-14)
HIV-infected infants respond poorly to childhood vaccination
It is known that HIV-infected children who do not receive appropriate antiretroviral drugs experience immune depression, and may become susceptible to infectious diseases that would otherwise be prevented by childhood immunization. view more (2007-12-05)
Older and poorer bowel cancer patients not given chemotherapy
Data were analysed from almost 8,000 bowel cancer patients under the age of 75, who were admitted to one of 59 hospitals in Scotland between 1990 and 1994. The results showed that 8 per cent of patients were given chemotherapy. view more (1999-11-15)
Vaccine for stomach flu may be possible, UNC research shows
Every year, millions of people are infected with noroviruses - commonly called "stomach flu" - often resulting in up to 72 hours of vomiting and diarrhea. While most people recover in a few days, the symptoms can lead to dehydration and - in rare cases, especially among the elderly and infants - death. view more (2008-02-14)
Potential leap forward in electron microscopy
MIT electrical engineers have proposed a new scheme that can overcome a critical limitation of high-resolution electron microscopes: they cannot be used to image living cells because the electrons destroy the samples. view more (2009-10-07)
Hidden sponges determine coral reef's nutrient cycle
Marine organisms hidden in caves, such as sponges, play an extremely important role in the nutrient cycle of coral reefs. view more (2005-09-15)
Spanish fertility experts bring hope of avoiding serious complication of assisted reproduction
Research by Spanish fertility experts is bringing new hope to women of avoiding a serious complication of assisted reproduction - ovarian hyperstimulation syndrome (OHSS)[1]. In its severest form, which requires urgent medical treatment, the syndrome affects around 200 women a year in Spain and as many as 2,000 a year in Europe. OHSS occurs when a... view more...
