Lemur 'Juliet' dies in Madagascar

...ed the captured lemurs were diademed sifakas, upon closer examination of the animals' markings and body characteristics the researchers concluded that the animals might represent a previously unknown subspecies of lemur. DNA tests are now under way to confirm the possibility. Captive breeding programs, suc...

Your heart is being closely watched while you're asleep

... more quickly, showing that the heart isunder much closer control during sleep. "It was totally counterintuitive," says Ivanov. The team initially thought the difference might come about because the body is resting duringsleep. Physical activity tends to cause changes in the heartbeat, which would lead to ...

Penny wise and pound-foolish: Study shows need for second pathologist's opinion

...ed in their original pathology reports is probably closer to 2 percent, Epstein says, because the study didn't consider patients wrongly given a clean bill of health from cancer. Such patients don't typically come to a large medical center for treatment. The researchers tallied only cases in whic...

Key progress by Weizmann scientists in the race to unravel ribosomal structure

...o near-atomic resolution ofribosomal structures is closer than ever before. Their approach and procedures have recently beenrepeated by a growing contingent of international researchers - all racing to elucidate the mystery ofribosomal functioning. According to Yonath, this understanding should pave the way...

'Frozen pictures' allow far-reaching glimpse into the cells protein factory

Their approach and procedures have recently been repeated by a growing contingent of international researchers - all racing to elucidate the mystery of ribosomal functioning (Science, Vol. 285, p. 2084, 2095 and 2133;Nature, Vol. 40...

Rotational motion detected in gates controlling nerve impulses

... these other amino acids moved apart, others moved closer together, and still others didnt appear to move at all. "These motions are not consistent with a simple translational movement, like that of a plunger moving up and down within the membrane," Bezanilla said. "But a rotational motion - like the turni...

Gene mutation results in missing teeth

Scientists at the University of Texas-Houston Dental Branch and the Baylor College of Medicine discovered the PAX9 mutation in a family in which congenitally absent molars were documented in members of three gen...

Scientists link gene to uterine dysfunction

... the mice appeared surprisingly normal. To take a closer look, Choo and colleagues have now mutated the protein in three genetically distinct mouse strains and examined the effect across all strains. The mice again appeared generally normal, except the males had somewhat reduced testis weight and the fema...

'Pathfinder' bees use optical odometers, suggesting microsurveillance technologies, Science author says

... farther the journey to food. If a meal is located closer than 50 meters, bees simply turn a few circles, performing what's called a "round dance." In the late 1960s, other researchers had suggested that bees determine the distance to food based on the amount of energy expended during flight, Thomas Colle...

Isolated Barbados population helps researchers zero in on asthma and allergic disease genes

...of genes for asthma and allergic disease has moved closer to identifying those genes with the help of a unique Barbados island population. "Allergic disease involves multiple genes and is incredibly complicated, making it hard to sort out genetic and environmental factors," says Kathleen Barnes, Ph.D., th...

UF dental researcher develops genetically altered bacteria strain that may fight cavities for a lifetime

Even if Hillman's new strain is successful, it will never replace a good toothbrushing. "Good dental hygiene will always be necess...

Exposures to second-hand smoke lower than believed, ORNL study finds

...aid. "In these micro-environments, a person may be closer to or farther away from various sources of environmental tobacco smoke." Over the last six or seven years, more data on personal exposure to tobacco smoke has become available and the methods for measuring and analyzing the smoke have become more sop...

Researchers unlock secrets of directional cell movement

... The finding, he says, brings researchers one step closer to understanding this chemical-sensing mechanism and using it to develop treatments. "If we understand the process of chemotaxis, in the future we may be able to encourage or inhibit it," says Devreotes. "This could be beneficial in encouraging wo...

Fossil plants' ties to ancient carbon redefined

...n than how much CO2 is in the atmosphere, but it's closer to the heart of what we want to know about how carbon inhabits chemical spheres of the earth, and how that affects climate." Data on the plants and their environments revealed a number of factors that could disrupt connections between carbon dioxid...

USGS scientists find new population of Asian swamp eels in south Florida

...wly discovered Homestead population is genetically closer to animals from populations originating in southeast Asia, whereas the populations found previously in the Miami and the Tampa areas are nearly identical to samples from more northern parts of China. To determine the abundance and more precise dis...

Yale researchers pinpoint possible causes of dizziness in the elderly/study suggests dizziness is a geriatric syndrome

...ess as a geriatric syndrome, researchers might get closer to identifying the causes of this condition. The study's goal, Tinetti said, was to determine the prevalence of dizziness episodes that last for at least one month. Tinetti's team set out to identify potential characteristics that predispose to dizz...

Scientists clarify much-sought enzyme, pave road to cancer therapy

... the enzyme's vulnerable spots. "This puts us far closer tofinding a way to inhibit it," says molecular biologist Carol Greider,Ph.D., who led the team. After cloning the gene for the "business end" of the telomerase molecule in32 different animals -- from shrew to elephant -- the researchers comparedthe ...

"These populations are clearly stressed, but whether this is due entirely to the chytrid fungus or is a combination of stressors acting in concert, we don't know." Pessier examined dead toads collected in 1998 and found that char...
