Massive coral death attributed to earthquake

Scientists have reported what is thought to be one of the world’s greatest mass death of corals ever recorded as a result of the earthquake in Aceh, Indonesia on 28 March 2005. The recent survey by scientists from the Wildlife Conservation Society - Indonesia Program and the Australian Res...

Newborn brains grow vision and movement regions first

...owing birth, while the area that controls abstract thought experiences very little growth during the same period, University of North Carolina at Chapel Hill researchers have found. The researchers discovered that the back regions of the brain, which control vision and sensory integration, grew significantl...

Research finds music training 'tunes' human auditory system

...an evolutionary standpoint, the brainstem once was thought to only play a passive role in auditory processing...een the brainstem -- a lower order brain structure thought to be unchangeable and uninvolved in complex processing -- and the neocortex, a higher order brain s...

Renegade RNA -- Clues to cancer and normal growth

...y in the wrong place at the wrong time for what we thought it was supposed to be doing that we just had to figure out why," says Hun-Way Hwang, a graduate student in human genetics and contributor to the study. Consisting of only 20 to 25 nucleotide building blocks (compared to other types of RNA that ca...

NASA predicts nongreen plants on other planets

...less than the other colors. Previously, scientists thought plants are not efficient as they could be, because they do not use more green light. According to scientists, the Sun has a specific distribution of colors of light, emitting more of some colors than others. Gases in Earth's air also filter sunli...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

In a venture once thought to lie outside the reach of science, researchers f...replaced by mineral. This substitution process was thought to be complete by one million years. "For centuries it was believed that the process of fossiliza...

Antifungal drug kills TB bug

... a highly contagious disease of the lungs that was thought to have been virtually eliminated by the 1960s, but is now resurgent and kills nearly two million people worldwide every year. New infections are occurring at a rate of one per second. Of equal concern is the dramatic rise in the incidence of new ...

Wired for sound: How the brain senses visual illusions

...le sensations can happen much more rapidly than we thought before," said Mishra. "We show physiological evidence that visual and auditory stimulation might not be processed separately, then merged together, as previously assumed, but that an almost-simultaneous integration of the sensations may actually tak...

A rarity among arachnids, whip spiders have a sociable family life

...cting with their siblings." Scientists have long thought these creatures were solitary and cannibalistic predators, as past studies have focused mainly on the adult's dramatic courtship and fighting behaviors. Rayor believes that because young amblypygids slip easily into tight crevasses and their coloring...

Why doesn't the immune system attack the small intestine?

...osis. "We've discovered that cells not generally thought of as part of the immune system actually play an important role in protecting the intestine from immune system attack," says Turley. "Because the cells are found in lymph nodes throughout the body, they may offer a way of suppressing a variety of aut...

Researchers discover gene crucial for nerve cell insulation

...s in a loss of feeling in the extremities, also is thought to involve myelin production. Dr. Svaren added that it is possible that the current study's findings about myelin production in the peripheral nervous system could lead to greater understanding of how myelination takes place in the central nervou...

New findings blow a decade of assumptions out of the water

...ions than had been assumed. Because it has been thought that nitrogen fixation is limited without enough iron, the conventional wisdom for the past decade dictated that the Atlantic Ocean would be the prime site for fixing nitrogen. That's because compared to the other low-latitude oceans, the Atlantic is...

New cell type identified in cancer development

...trast to the behavior of normal stem cells. "We thought this was an interesting development," says Gao, "because these precancerous cells were actually stopped from becoming malignant. We are calling this process ‘differentiation-induced cell death,?a protective mechanism the body may invoke to prevent pC...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...there was ten times as much DNA than we originally thought there would be," says lead author Jane M. Carlton,...lly, the researchers were able to analyze proteins thought to be linked to the parasite's hydrogenosome--its energy source and the target of the two drugs appr...

Canadian study shows bilingualism has protective effect in delaying onset of dementia by four years

Now scientists with the Rotman Research Institute at the Baycrest Research Centre for Aging and the Brain have found the first evidence that another lifestyle factor...

At over five years into the study’s follow-up, the researchers found that approximately 98 percent of subjects still maintained protection against HPV types 16 and 18. Regardless of HPV...
