Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

...ere is no evidence that ceasing consumption of the suspect foods will reduce heartburn, some of the studies did show that certain of the foods (such as chocolate and carbonated beverages) can reduce the pressure exerted by the esophageal sphincter, the control valve that keeps the food you've swallowed and y...

Researchers map out networks that determine cell fate

Ocean acidification threatens cold-water coral ecosystems

... worrisome declines," says Guinotte. "But now we suspect that this increase in CO2 will have a detrimental effect on cold-water corals as well. Cold-water reefs are at greater risk than shallow-water reefs because colder waters are naturally less hospitable for coral growth." The uptake of CO2 by oceans ...

Anti-inflammatory drug's potentially deadly side effect found to be rare

...h the disorder, PML experts like Clifford strongly suspect an immune system connection. "As many as half of all adults are infected with the virus that causes PML, which normally doesn't bother us," he says. "It only becomes a problem in those with suppressed immune systems, where it can enter the brain an...

'Scent of a woman' tells male redback spiders to find a mate

... were smaller but had more fat on their body. They suspect that these males need the extra fat for the extended courtship rituals preferred by females -- males are supposed to pluck and vibrate a female's web strings for up to eight hours -- and displeased females will flick males away or even off the web. ...

Nobelist discovers antidepressant protein in mouse brain

... functional. This finding led the researchers to suspect that p11 levels might be directly involved in the development of depression, anxiety and similar psychiatric illnesses thought to involve faulty serotonin receptors. To test this idea, the researchers examined p11 levels in the brains of depressed hu...

UF scientists trace origin of shark's electric sense

...nable people to keep their balance. But scientists suspect as human ancestors emerged from the sea, they discarded their lateral lines as well as their ability to sense electrical fields. "Our fishy ancestors had the anatomy for it," said James Albert, aformer UF biologist who is now at the University of Lo...

One in 14 men having a heart attack drive themselves to hospital

...ncouraged to call an ambulance immediately if they suspect they are having a heart attack" concludes Dr O'Donnell. "And it's also time to challenge the image of the typical male heart attack victim. "We are particularly concerned that women face much longer delays, both in the time it takes them to g...

Dogs keep dying: Many owners unaware of toxic dog food

...te http://diaglab.vet.cornell.edu/news.asp . "We suspect that dogs have been dying since November, perhaps even October, but it took the perfect storm of circumstances to get the diagnosis," said Karyn Bischoff, the veterinary toxicologist at Cornell who first identified aflatoxin as the culprit in the rec...

Cuttlefish masters of disguise despite colorblindness

... of at least 15%, which Mäthger and her colleagues suspect might be a critical factor in uncovering what determines camouflage patterning in cuttlefish. Despite these results, the vexing question of how cuttlefish master the task of camouflage in low-contrast, color-rich environments such as those found at ...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...e normal healthy brain. Their findings led them to suspect that the primary role of the immune system's T cells (which recognize brain proteins) is to enable the "neurogenic" brain regions (such as the hippocampus) to form new nerve cells, and maintaining the individual's cognitive capacity. The research tea...

DNA conclusive yet still controversial, Carnegie Mellon professor says

Some critics claimed that this practice could snag an innocent person, but Roeder has demonstrated through her own research that the likelihood of a false hit are miniscule -- in one ca...

UCLA scientists find male gene in brain area targeted by Parkinson's

...mine-producing cells in the substantia nigra. "We suspect that estrogens in women could play the same role as SRY in protecting the female brain from Parkinson's disease," he said. "Our lab is currently studying this hypothesis in an animal model." Sex differences in other dopamine-linked disorders, such a...

Mining for gems in the fungal genome

Keller also believes the mining strategy might work outside the Aspergillus genus with some modifications. "This is ...

Gene needed for butterfly transformation also key for insects like grasshoppers

... which other genes will be copied. The researchers suspect that broad must be present for the physical changes contained in those areas of DNA to be expressed. Suppressing broad prevents the changes from occurring. "Humans don't have the broad gene, but if they did and you suppressed it you'd have a baby th...

Growth hormone is made in the brain, report scientists

... steroids to increase muscle mass. The scientists suspect that reasoning and mood may also be affected by these differences in the amount of growth hormone in the brain. "Growth hormone has been associated with growth of muscles and bones, and the production of it was believed to lie mainly in the pituita...
