Open microfluidic and nanofluidic systems

...erials. It should also remain valid if one further 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 bee...

Max Planck researchers make a breakthrough in plant stem cell research

...o cancer. On the other hand, if the stem cell pool shrinks too quickly, the plant could have stunted growth. In order to stay alive and reproduce, the plant needs to find the right balance in the number of its stem cells. Two regulatory mechanisms were found to be important for this process. The first involv...

Basic research leads to a novel cancer therapy

...development in a tumour slows down its growth, and shrinks its tissue. This fundamental principle led to the development of SUTENT®, whose active ingredient is Sunitinib. SUTENT® was recently approved for clinical use in the United States, and it is expected to be brought onto the German market this year. W...

Recombination protein dynamics observed with single monomer resolution

...NA. The protein forms a filament, which grows and shrinks primarily by one monomer at a time, the researchers report in the August issue of the journal Cell. RecA is a DNA recombination protein found in the gut bacterium E. coli. A human homolog, called Rad51, interacts with many proteins, including BRCA2,...

UCLA researchers develop T-cells from human embryonic stem cells

...s is the organ where T-cells develop. It gradually shrinks in adults, weakening the immune system over time. These results indicate that it is possible to decipher the signals that control the development of embryonic stem cells into mature T-cells, said study co-author Jerome Zack, associate director of th...

Recurrence of a flu pandemic similar to infamous 1918 flu could kill 62 million

...n you look at the data," said Murray, "that number shrinks to about three or four percent." The disparities between the developed and developing worlds during this period are striking. For example, in Denmark 0.2 percent of the population succumbed to the flu. In the United States, that figure is 0.3 perc...

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

...ort at UCSD to develop a promising technology that shrinks what is currently being done in large genome-sequencing laboratories down to a glass slide the size of a business card. Huang's team will combine micro- and nano-fabrication technologies with innovative chemistry technologies to simultaneously sequen...

Large size crucial for Amazon forest reserves

... for Amazon Research, in Brazil. Fragmentation shrinks the Amazon forest by thousands of square kilometers every year, leaving a trail of small forest fragments isolated by cleared land. Many species that occur in intact forest prior to destruction will not be present in a small fragment, but would they ...

Want to save polar bears? Follow the ice

...tand the best chance of surviving as the polar cap shrinks in size. To that end, the project will utilize remote sensing satellite imagery on sea ice extent and concentration since 1978 to form a picture of polar bear habitat history as well as where this habitat most likely remain in the future under global...

Focused ultrasound relieves fibroid symptoms in women

A noninvasive ultrasound procedure effectively shrinks uterine fibroids and significantly relieves fibroid-related symptoms in women, according to the results of a multicenter clinical trial reported in the June issue of the journal Radiology. Magnetic resonance-guided, focused ultrasound surgery (MRgFUS...
