Out-of-body experiences may be caused by arousal system disturbances in brain

...They found those who had an out-of-body experience along with near death were more likely to also have had ...which can cause a condition of temporary paralysis along with visual or auditory hallucinations immediately after waking up or before falling asleep due to a...

Paper challenges 1491 Amazonian population theories

...ransformation; that you still had a bulk of people along the river but their influence extended deep into the forest. It's still nebulous, and difficult to get people to map stuff, or put hard numbers on it, but there is a sentiment that the Amazonia has been disturbed and that the view of the Amazonian ra...

Scientists genetically engineer tomatoes with enhanced folate content

...of Florida at Gainesville who developed the tomato along with colleague Jesse Gregory. "Now that we've shown it works in tomatoes, we can work on applying it to cereals and crops for less developed countries where folate deficiencies are a very serious problem." Folate is one of the most vital nutrients...

A 'traffic light' for neurons means 'go' for improving brain research

...ate student Feng Zhang, a lead author of the paper along with Stanford postdoctoral scholar Li-Ping Wang. If use of the technique can show that altered activity in a particular kind of neuron underlies symptoms, for example, this insight will allow development of targeted genetic or pharmaceutical treatmen...

Scientists identify molecular cause for one form of deafness

...eir orientation order ?that is, they point roughly along the same direction ?but lose their positional order. These nematic liquid crystals are commonly used in watch displays and laptop displays. Wong and his colleagues also found that a mixture of mutant espin and normal espin would prevent the structu...

Study shows isolation of stem cells may lead to a treatment for hearing loss

...cell to release an electrical impulse which passes along the auditory nerve to the brain. If the sound is too loud, the hair cells are damaged and no longer send signals to the brain. Severely damaged hair cells do not repair themselves nor do they regenerate naturally. While further research is nec...

Gene found for rare disorder may reveal new pathway in mental retardation

...esearch has unexpectedly showed that mutated genes along the cohesin pathway also cause specific abnormalit...uggests there may be other, undiscovered mutations along the cohesin pathway among patients thought to have isolated mental retardation." "This discovery ...

Pitt study notes decline in male births in the US and Japan

...We suspect that some combination of these factors, along with older age of parents, may account for decreasing male births.? Dr. Davis explained that environmental factors, such as prenatal exposure to endocrine- disrupting environmental pollutants may impact the SRY gene ?a gene on the Y chromosome th...

UCSD researchers discover variants of natural tumor suppressor

...ers have now found that PHLPP1 controls the driver along one pathway ?Akt2, which is more closely involved in maintaining a constant level of glucose in the bloodstream. Therapies directed at inhibiting PHLPP1 could be used to treat diabetes; in essence, removing the 'brake' and allowing Akt2 to be more f...

LIAI completes world's most comprehensive analysis on influenza virus data

...ging infectious diseases, such as West Nile virus, along with those diseases considered potential bioterrorist threats. The database's influenza research was analyzed first due to the continuing problem of seasonal influenza and public health concerns over the possible spread of the H5N1 avian flu. "The...

Prehistoric origins of stomach ulcers uncovered

...n H. pylori. Human DNA analysis has shown that along the major land routes out of Africa human populations become genetically isolated - the further from Eastern Africa a population is the more different genetically it is compared to other human populations. Other research has shown gradual differences...

Hotspots of mercury contamination identified in eastern North America

...ns from coal-fired electric power stations, which, along with municipal waste incinerators, are major sources of mercury pollution. Cap and trade approaches seek to reduce the total release of mercury but could lead to static or increased emissions in some areas. Greater deposition of mercury near areas th...

Are one-third of costly implanted heart devices unnecessary? New study suggests yes

... a test called microvolt T-wave alternans or MTWA, along with a battery of other tests, during their evaluation. Half of the patients went on to receive ICDs, although the MTWA test results weren't used in the decision-making process. The patients' health and the causes of any deaths were tracked for up to...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

Synthetic peptide targets latent papilloma virus infections

...s not be left behind, and are copied and delivered along with the duplicate chromosomes into the daughter cells, where they again take up residence in the nucleus as latent viral DNA. The viral plasmids turn into infectious viruses only in the top, differentiated layers of tissue. Previous work showed th...

UTSA researchers examine effects of global warming on Antarctic

... are seeing some regional increases in the sea ice along with regional decreases," said Ackley. "If you look at the totality of it, it appears as if it hasn't changed very much over the last 30 years, but it has. Even though we're only seeing these regional changes and not a systemic decline in the amou...

Massive coral death attributed to earthquake

...a, in March 2007. The surveys covered 35 sites along 600 kms (372 miles) of coastline, have documented, for the first time, the effects of earthquake uplift on coral reefs. The entire island of Simeulue, with a perimeter of approximately 300 km (186 miles), was raised up to 1.2 m (3.9 feet) following t...

A genetic 'gang of 4' drives spread of breast cancer

...e, Massagué and his colleagues at Sloan-Kettering, along with researchers from Hospital Clinic de Barcelona and the Institute for Research in Biomedecine in Spain, focused on four of these genes. These genes, which code for proteins called epiregulin, COX2, and matrix metalloproteinases 1 and 2, were alrea...
