Baby fish 'smell their way home'

... parents' mouths. "An egg, even a fry, hasn't a fully developed sense of smell, but it may have a way of absorbing the local molecules and then recognizing their signature as "home" when it grows up a bit and is ready to settle," Mike says. "This evidence that individual coral reefs play such a key r...

Magnetic system could be key to surgery without scars

...velop new techniques. Also, until the system is fully tested in humans, surgeons won’t know whether fewer entry points will result in fewer complications or faster healing, advantages usually seen in moving from conventional surgery to laparoscopic surgery. ...

Anti-dandruff compound may help fight epilepsy

... them. Plus, this study really shows that we don’t fully appreciate the biological roles of many familiar chemicals that surround us.? ...

Genomics throws species definition in question for microbes

...ification framework in use today is not capable of fully portraying and organizing microbial diversity." The report contains an in-depth review of the myriad issues and conflicts involved in the classification of microbes in the post-genomic era, including a discussion on the definition of the term "sp...

When smell cells fail they call in stem cell reserves

...l, and it’s important that the olfactory system be fully operational all the time,?explains Reed. “The HBCs act as a fail-safe to ensure continued function of the sense of smell.? The discovery of these two distinct types of stem cells in one neural tissue is a first, says Reed, who is interested to see...

Low levels of neurotransmitter serotonin may perpetuate child abuse across generations

...mportant implications for humans because we do not fully understand why some abused children become abusive parents and others don't," Maestripieri said. The research suggests that treatments with drugs that increase brain serotonin early in an abused child's life could reduce the likelihood that the child...

OHSU researchers demonstrate how white blood cells cannibalize virus-infected cells

... in the OHSU School of Medicine. "While we don't fully understand why this happens, one possibility is that the T-cell consumes virus-infected cells to fuel itself in the continued fight against an ongoing infection. It's sort of like invaders that pillage their defeated foe's supplies and then continue ...

Seagrass ecosystems at a 'global crisis'

...oup of flowering plants that have adapted to exist fully submersed in the sea ?profoundly influence the physical, chemical and biological environments of coastal waters. They provide critical habitat for aquatic life, alter water flow and can help mitigate the impact of nutrient and sediment pollution. ...

Uncovering DNA's 'sweet' secret

...e genetic information. The findings suggest that fully hydroxylated six-carbon sugars probably would not have produced a stable base-pairing system capable of carrying genetic information as efficiently as DNA. "The structure now provides insight of a chemical nature that (the six-carbon sugar) is just...

Underweight women at greater risk of miscarriage

...the causes of the majority of miscarriages are not fully understood. Many supposed risk factors, for example alcohol consumption, smoking and caffeine intake, remain controversial or unconfirmed. The researchers questioned 603 women aged 18-55 in the UK whose most recent pregnancy had ended in first tr...

New gene linked to bipolar disorder

...g techniques such as animal models will help us to fully understand the mechanisms behind this gene and explore how we might be able to intervene in these mechanisms, to help people with the disorder. "We hope our discovery will eventually lead to new treatments for depression and bipolar disorder, incl...

Cracking the egg

NHGRI aims to make DNA sequencing faster, more cost effective

...esis" This team of investigators has developed a fully automated instrument capable of sequencing single molecules of DNA on a planar surface. The group is now developing a high-throughput version of this technology for the re-sequencing of whole human genomes. The sequencing strategy involves obtaining ...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...entional flu vaccination takes 2-3 weeks to become fully effective. Experiments so far show that a single dose of protecting virus can be given 6 weeks before an infection with flu virus and be effective. This could also have a substantial advantage over anti-viral drugs that only give less than 24-hour ...

Study uncovers mutation responsible for Noonan Syndrome

... the identity of the gene or genes responsible for fully half the cases had not been elucidated," Neel said. To identify candidate genes, a group led by HMS instructor Amy Roberts, MD, and director of HPCGG Raju Kucherlapati, PhD, conducted genetic analysis of over 100 children with Noonan syndrome. Thi...

Some 40 million LCD television sets were sold worldwide last year with expected sales likely to top 100 million by 2009. Now scientists in the Department of Chemistry at the University of York have won a major DTI competit...

First major study of mammalian 'disorderly' proteins

"This work further illustrates that the disorderliness of IUPs isn't just a curiosity," said Charles Galea, Ph.D., a p...
