New research identifies anti-viral protein that may predict who might be at risk to develop lupus

...n something else, perhaps an environmental factor, pushes the immune system to the breaking point and causes the production of the damaging autoantibodies. The high level of interferon-alpha doesnt always cause the disease, because many healthy family members have high levels, says Dr. Niewold, who is no...

Doctors have tried treating GBM patients with drugs that inhibit EGFRvIII, but they have had little effect. This could be because the continuous stimulation of the receptor is so intense and because the receptor ...

Origins of nervous system found in genes of sea sponge, report scientists at UC Santa Barbara

... in synapses of humans and mice, said Oakley. This pushes back the origins of these genetic components of the nervous system to at or before the first animals much earlier than scientists had previously suspected. When analyzing something as complex as the nervous system, it is difficult to know where t...

Crammed with charged DNA, pressure rises inside virus

...s to measure the forces exerted by the motor as it pushes the DNA into the capsid. The virus motor has to do mechanical work to overcome two factors that create resistance, said Douglas Smith, an assistant professor of physics at UCSD who headed the team that published the discovery this week in the ...

Brazil demonstrating that reducing tropical deforestation is key win-win global warming solution

...ng years as worldwide demand for biofuel and grain pushes agriculture deeper into tropical forests. "Slowing tropical deforestation wont, by itself, solve the climate problem," said Dr. Peter Frumhoff, co-author and organizer of the study and Director of Science and Policy at the Union of Concerned Scien...

Deactivating protein may protect nerve fibers in MS

...le Sclerosis Research to support MS research that pushes traditional boundaries to discovery. The discovery by Forte, Bourdette and their team, which was funded in part by the foundation, fits the bill, he said. "It goes to prove that sometimes the big breakthroughs do not come from the more traditional ...

AGU Journal highlights -- February 23, 2007

...s of global ocean circulation, the convection that pushes surface waters downward and brings deep waters to the surface depends on the ability of a water parcel to mix vertically with surrounding waters. Tidal currents that interact with undersea topography to form waves called internal tides supply the ene...

Study finds oysters can take heat and heavy metals, but not both

...ter temperatures for a few months, the combination pushes them to a crisis point where any further change (such as seasonal temperature increases caused by global warming) can make their survival unlikely. Oysters are right at the boundary already, she said. Some earlier studies show that oysters stop gro...

Fossil is missing link in elephant lineage

...vered in the East African country of Eritrea, also pushes the origins of elephants and mastodons five million years farther into the past than previous records, Sanders said.

Scientists find lamprey a 'living fossil'

...early complete soft tissue impression, but it also pushes back their fossil record another 35 million years. "These are pretty insubstantial animals," Coates said. "Lacking a boney skeleton, they rot down, leaving no hard parts, like a skull or ribs. So if a fossil site is discovered that yields impressio...

Space radiation threats to astronauts addressed in federal research study

Researchers have been stepping up studies on radiation biology and space shielding in recent years, said the University of Colo...

Grape seed extract halts cell cycle, checking growth of colorectal tumors in mice

...that effectively freezes the cell cycle, and often pushes a cancer cell to self destruct. "With these results, we are not suggesting that people run out and buy and use grape seed extract. That could be dangerous since so little is known about doses and side effects," said Rajesh Agarwal, Ph.D., professor ...

To produce the map, Gaffin and his...

ANU scientists crack DNA replication mystery

... replisome tracks along one of the DNA strands and pushes the other one off it," Professor Dixon said. In certain bacteria, a small protein called TUS binds to the last part of DNA to be copied in a way that stops the replisome when it faces in one direction, but not in the other. How it can work this way...

Ants are surprisingly ancient, arising 140-168 million years ago
