Researchers find first evidence of venom system in extinct mammal

...ver the years from the banks of the Blindman River near Red Deer, Alberta. Sun immediately took the fossil to Scott, who thought it was the first proof of a venomous capacity in an extinct mammal, but he took it to Fox to confirm his notion. Fox and Scott had found individual canine fossils with similar...

Genetic links could unlock clues to leading cause of blindness

...e-ranging monkeys on the island have multiplied to near 1,500, but because the rhesus monkeys are not native to the area, they could mate only with each other. This inbreeding has predisposed the monkeys to various genetic diseases, such as age-related macular degeneration. Unlike most other animals, a r...

Achilles heel of the herpes virus possibly found

...nd studying the HSV entry mechanism was tricky and near impossible until Fuller's team discovered a type of pig kidney cell that isn't vulnerable to infection by human herpes virus. They searched the genome library to find genes essential to HSV infection, isolated the B5-coding sequence, and figured out ...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

...weeks at two sites in the Red Sea's Gulf of Aqaba, near the coral reef of Eilat in Israel and at Ras Burka on the coast of Egypt's Sinai Peninsula. At the sites scuba divers attached Fish TV's sonar head ("transducer") on a large underwater tripod raised some 20 feet above the seafloor. The transducer was...

Deep sea algae connect ancient climate, carbon dioxide and vegetation

...y, with a sharp decrease and then stabilization to near modern day levels between 34 - 25 million years ago. During the early part of the Paleogene Period, from 65 - 34 million years ago, global climates were much warmer than today with very little ice present at the poles. The boundary of the Oligocene ...

Purdue scientists may have found key to halting spinal cord damage

... about three days it has leveled off at a point of near non-functionality. "What our group did was measure the levels of acrolein in the injured spines of 25 guinea pigs for several days following an injury," Shi said. "We found that levels of acrolein peak 24 hours afterward, and they remain high for at...

New insights into how Huntington's disease attacks the brain

...teins exert their influence on brain cells located near the target cells," he said. "These neighboring cells then interact with the target cells to spark disease." To pinpoint the disorder's cellular origin, UCLA researchers developed two sets of mice with the human HD gene mutation. The first group was ...

Could better mangrove habitats have spared lives in the 2004 tsunami?

...ffer protection from the tsunami. Mangrove fringes near the water's edge appeared to take most of the energy from the tsunami waves, and they showed evidence of damage in some cases, but the researchers found few examples of mangrove trees actually being uprooted. However, mangroves at numerous sites had...

New complete muscle grown in the lab

...uscle tissue when needed," Levenberg says. In the near future, Levenberg explains, a simple muscle biopsy might provide the "seed" cells for a person's own engineered replacement muscle. For example, the lab-grown muscles could replace tissue lost to severe trauma such as burns, or build up muscle that h...

Identification of specific genes predicts which patients will respond to Hepatitis C treatment

...t just does not work," said Dr. McGilvray. In the near future, determining the levels of a small subset of genes in patients' liver biopsies, with perhaps a simple blood test, may be helpful in deciding who will respond to treatment of chronic Hepatitis C with the current combination therapy using the sy...

Vietnam war technology could aid elephant conservation

...iraffes, lions and humans, using a geophone buried near a path leading to a watering hole in Namibia's Etosha National Park. Because of the differences in the size and frequency of animals' footfalls, the researchers could tell with 82% accuracy when elephants were passing the geophone and estimate the nu...

Plankton can run, but can't hide from basking sharks

However, this study shows that basking sharks seem to ha...

Scientists focus on 'dwarf eye'

...sightedness) -- the ability to see only distant or near objects clearly, respectively -- stems from the complex growth of the human eye. All human eyes have a slight degree of farsightedness at birth. As the child grows and gains more visual experience, the eye adjusts its focus by growing, which changes ...
