Open microfluidic and nanofluidic systems

...her shrinks the surface channels and, in this way, moves deeper into the nanoregime. As one reaches a channel width of about 30 nanometer, one theoretically expects new effects arising from the line tension of the contact line, but such nanochannels have not been studied experimentally so far. The new PNAS...

The study moves the date of human skulls found in Ethiopia's Kibish rock formation in 1967 back from 130,000 years to a newly determined date of 195,000 years ago, give or take 5,000 years. Fossils from an individual known as Omo I look like bones of modern humans, ...

Map of human genetic variation across populations may promise improved disease treatments

...bined or shuffled out of the sequence block as DNA moves from parent to child. Conversely, if the variations are closer together, they are more likely to remain together following DNA recombination over generations. At the same time, she said, haplotype blocks of genetic sequences containing genetic variat...

Brain controls robot arm in monkey, University of Pittsburgh researcher reports at AAAS

...r researcher on the project. The neural prosthesis moves much like a natural arm, with a fully mobile shoulder and elbow and a simple gripper that allows the monkey to grasp and hold food while its own arms are restrained. Computer software interprets signals picked up by tiny probes inserted into neuronal...

Robots walk with close-to-human efficiency

... The most famous current example, the Honda Asimo, moves smoothly but on large, flat feet. And compared with a person, it consumes much more energy. But researchers at Cornell University, the Massachusetts Institute of Technology (MIT) and Holland's Delft University of Technology have built robots that se...

Wetlands clean water and may control neighborhood flood problems

...ce for water to go. Building dikes and levees just moves the water problem somewhere else, causing flooding elsewhere." Because golf courses are mostly open surfaces, as opposed to all the hard surfaces in subdivisions and shopping malls, water can soak into the soil and flow into a constructed wetland, he...

Researchers discover a good side to cholesterol in controlling cell signals

...s of cholesterol. While studying how cholesterol moves to the membrane to get to lipid domains, Dr. Anderson, who holds the Cecil H. Green Distinguished Chair in Cellular and Molecular Biology, and colleagues found that cholesterol can work outside the membrane to regulate a key signaling pathway that oc...

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...I'm really excited by our findings. This progress moves us one step closer to drugs that work by switching telomerase on permanently and keeping the immune cells young and strong in their fight against infection," said Effros. "These therapies are also easier to develop than gene-therapy drugs." The rese...

Shutting down the HIV assembly line

...rs, Spearman said, it has become apparent that Gag moves to a compartment in the cell called the multivesicular body, or late endosome. In some cell types, Gag and the HIV viral envelope protein form particles in the multivesicular body; in other cell types, Gag makes its way from this site to the cell mem...

Something to sing about: Vocal cord regeneration moves a step closer to reality In a development that could help restore voices that are lost due to injury or disease including voices of some well known singers researchers at Massachusetts Institute of Technology say they have moved a step closer to e...

As the project moves into the design phase, faculty and students from the School of Art's Visual Communications Research Studio will develop concepts to demonstrate how the vehicle might communicate its content. The studio will also explore several approaches to the desi...

Vital step in cellular migration described by UCSD medical researchers

...s serve as tractor sites for migration as the cell moves toward its intended target. If Rac were active throughout the cell, it would extend protrusions in all directions, in essence keeping the cell in one place. Until now, researchers have had limited understanding of the molecular mechanism that inhib...

Discovery of gene will likely lead to new treatments for inflammatory diseases, cancer

...heir respective genes) bind to form a complex that moves into the cell's nucleus to regulate the transcription of cytokines. The recent Boston University findings will offer new ways to regulate TNF-alpha, whose overexpression causes inflammatory and immunological problems. Drugs regulating TNF-alpha such...

U of M researcher examines newly emerging deadly disease

...cted by Staphylococcus aureus. The infection then moves to the lungs, making superantigens (bacterial toxins that activate large numbers of T cells), often leading to death due to hypertension and shock. Purpura fulminans has been identified in five cases in the Minneapolis-St. Paul, Minn., metropolitan ...

Researchers improve design of genetic on-off switches

Such selectivity moves researchers closer to designing synthetic molecules that will attach to only targeted receptors to activate or deactivate desired gene expression in living systems, which could lead to advances in such applications as gene therapy, metabolic engineer...

Researchers unmask malaria parasite's cloaking mechanism

...said Crabb. "Every now and again, one of the genes moves into the right spot and gets activated." Because some var genes are located near each other, Cowman said, sometimes more than one var gene is moved into a compartment at the same time. Since this does not result in the simultaneous expression of mult...

Molecular motors cooperate in moving cellular cargo, study shows

The results of this study could have direct, major impacts on the development of mercury emission standards. CONTACT: James Hurley, (608) 262-1136, hurley@aqua.wisc.edu ...

Study reveals dramatic difference between breast cancers in US and Africa

... disease that is less common but starts sooner and moves faster. Obviously an annual mammogram beginning at 50 is not the best route to early detection in African women, who get the disease and die from it in their 40s, and it also needs to be adjusted in African Americans and high-risk women in all racial...

Immune system's initial response to cancer under study

...e immune system. When cancer spreads, it typically moves through this natural drainage system. If all goes well, long before that happens, the body has seen and eliminated the cancer, says Dr. Kraj. Very early in the disease process, immune cells called dendritic cells take cancer antigens and all antige...
