MIT designs portable 'lab on a chip'

...posing slip velocities at different heights, which combine to push the fluid in one direction, like a conveyor belt. Simulations predict a dramatic improvement in flow rate, by almost a factor of twenty, so that fast (mm/sec) flows, comparable to pressure-driven systems, can be attained with battery voltages...

Beyond the book: Software automates access to brain atlases

Climate experts search for answers in the oceans

...developing a data set of global ocean colour, both combine data measured independently by several different satellite systems into a set of products that represent the best possible measurements and allow researchers from various fields to pool their efforts in an attempt to understand how the climate is rea...

Stem cells found in adult hair follicles may provide alternative to embryonic stem cells

...ge of hair follicles and have characteristics that combine some advantages of embryonic and adult stem cells, according to lead researcher, Maya Sieber-Blum, Ph.D., professor of cell biology, neurobiology & anatomy. Similar to embryonic stem cells, they have a high degree of plasticity, can be isolated a...

Rising ocean temperatures, pollution have oysters in hot water

... that the combination of temperature and pollution combine to intensify the stress placed on the oyster's physiological system. In future experiments, the researchers will try to determine whether the combination of temperature and pollution is preventing oysters from obtaining enough oxygen or whether it...

Scientists win grants to develop $1,000 genome sequencing technology

Huang's team will combine micro- and nano-fabrication technologies with innovative chemistry technologies to simultaneously sequence more than 1 billion individual pieces of DNA attached to the surface of single slides. The latest genome-sequencing grant was announced simu...

Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

...er markets. ATRP's strength lies in its ability to combine chemically diverse subunits (monomers) into multiple arrangements that create specialized polymers. This technology enables production of "smart" materials that can respond intelligently to altered environments, such as changes in pressure, acidity, ...

Elusive rust resistance genes located

The marker has proven effective in a range of wheats from different backgrounds including from Australia, India, China, North America and the major wh...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

...erapy," said Owens. Antiretroviral therapies now combine multiple individual drugs to reduce the amount of virus in a person's body. The cumulative effect of two or three medicines works better than a single one to keep the virus at bay. Antiretroviral therapies have the added benefit of reducing the c...

Researchers seek to design first treatment for neuroAIDS

...ve a successful therapy for neuroAIDS will need to combine standard antiviral combination therapy with new drugs that both protect nerve cells from toxins and reduce inflammation. The new grant, from the National Institute of Mental Health, is a competitive renewal of a previous grant, but with a shift in ...

Researchers find gene mutation that causes infertility in male mice

...sex cells contain only one set of chromosomes that combine during conception and create an embryonic cell with two chromosome sets, one from each parent. The mutation leads to a change in an amino acid in Dmc1 that blocks meiosis in its tracks, preventing sperm production. The mutant allele (one version of...

Researchers design pulsed mircrojet system to deliver protein drugs without pain or bruising

...he pulsed mircrojets engineered by the researchers combine high velocity (more than 100 meters per second) with very small jet diameters (between 50 and 100 micrometers), delivering only 2 to 15 nanoliters of liquid drug at a time. The research showed that the pulsed microjet system could be used to effecti...

Transfusion expert urges wider use of filtered blood
