Study shows big power of small RNAs, not just proteins, in halting cancer

...tor (HHMI) Greg Hannon have identified a family of micro RNAs (miRNAs) that enable a critical tumor suppressor network, called the p53 pathway, to fight cancer growth. “At CSHL, we are moving simultaneously on several fronts to understand the p53 pathway because damage to this pathway is something that al...

Grape expectations for healthier wine

...packages of grapes at 0 degress C to cycles of 0.1 micro liters per liter of ozone. They found that ozone treatment was 90% as effective as SO2 at preventing decay. In addition, ozone-treated grapes had up to four times more antioxidants than untreated grapes (Journal of the Science of Food and Agricultu...

Biologically inspired sensors can augment sonar, vision system in submarines

...ral line consists of an integrated linear array of micro fabricated flow sensors, with the sizes of individual sensors and spacings between them matching those of their biological counterpart. "By detecting changes in water pressure and movement, the device can supplement sonar and vision systems in subm...

Bones at the nanoscale

...rangement of organic and inorganic components at a micro and nanoscale level under tensile stress. The scientists realised that when strain/pressure is applied to a bone, this is ab-sorbed by soft layers at successively lower length scales, and less than a fifth of the strain is actually noticed in the ...

Squid-inspired design could mean better handling of underwater vehicles

...est. The team also has designed a series of other micro vehicles for air and underwater use. A National Science Foundation grant is funding their research....

Ferns provide model for tiny motors powered by evaporation

...materials that could provide a method for powering micro and nano devices with just water or heat. "We've shown that this idea works," said Michel Maharbiz, assistant professor of electrical engineering and computer science and principal investigator in the group that built the device. "If you build these...

Most widely used organic pesticide requires help to kill

...e between five hundred and one thousand species of micro flora that take up residence in the intestinal tract. "In moths and butterflies, the complexity is much lower than in mammals, and even some other insects," Broderick explains. The Wisconsin study was conducted using antibiotics to clear all of t...

Mining biotech's data mother lode

...e analyses over-expressing genes discovered during micro assays to establish what proteins become encoded. This uses standard techniques.A second analysis tool in the suite predicts what possible protein-protein interactions are taking place. This is novel. When a gene encodes a protein, the protein folds ...

Software 'agents' could help unmask reality of disease clusters

...ch widespread concerns can only be addressed using micro data and access to this often involves lengthy and cumbersome procedures through review boards and committees for approval, and sometimes it is just not possible." Dr Boulos, together with colleagues from the Department of Computer Science at the Un...

New RNA polymerase discovered in plants

...rth polymerase was involved with what are known as micro RNAs, which are known to regulate flower development, but that proved wrong." In a series of genetic and biochemical tests , Pikaard and his collaborators discovered that Pol IV does not share in the duties of Pol I, II or III. But when the Pol IV s...
