K-Staters design and build a low-cost remote sensing tool for environmental studies

...tists, who would then be able to reconstruct it to obtain high-resolution images and reliable data. The development of the sensing tool is part of a three-year research instrumentation project that began in fall 2005 with a $597,000 National Science Foundation grant. The researchers are Dale Schinstock, a...

Harmful Algal Blooms monitored from space in Chile

... strategic decisions for farm site location. "To obtain the amount of information covered with the EO data, alternative methods will be of considerable higher cost. With in situ measurements you cannot produce a gradient map as obtained with EO images. The value of this information is the area and resolut...

Wild meerkats school their young

...e discovered that older meerkats teach pups how to obtain food by incrementally introducing dead, injured and then live prey. Although learning per se wouldn't be surprising, whether wild mammals teach their young was still debated. The findings were published in this week's edition of the journal Science...

Scientists identify protein with a crucial role in cell death

...d unknown for a long time. 'Knock-out' mice To obtain insight into PARL's function, the researchers used mice ?called 'knock-out' mice ?that were no longer able to produce this protein. These mice deteriorated very rapidly ?losing muscular strength after only 4 weeks, which greatly reduced their capacit...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...th care professionals and environmental experts to obtain precise biochemical test results with only micro-level amounts of fluids. "By manipulating droplets so carefully and preventing contamination of the samples, we can detect things like signs of disease or environmentally hazardous materials much be...

Bumble bees can estimate time intervals

...r in which bumble bees extended their proboscis to obtain sucrose rewards, the researchers observed that bees adjusted the timing of proboscis extensions so that most were made near the end of the programmed interval between rewards. When nectar was delivered after either of two different intervals, bees co...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

...is if we can optimize our yield we can more easily obtain the large number of specific cells required to make a blood vessel." ...

New lab technique churns out fungus' potential cancer fighter

...revious method. For the first time, scientists can obtain enough rasfonin to conduct proper biological tests on it. "At a guess, I'd say that rasfonin itself will not be the final compound that might come to market," says Boeckman. "But we need to figure out how it works, how it triggers the cancer cell to...

AIDS-related cognitive impairment exists in two separate forms

...vealing how oncologists should treat the cancer to obtain the best outcome. Currently, physicians cannot predict which patients with prostate cancer should receive extra therapy after surgery - or whether some of these patients have an indolent disease that does not even require surgery. Most patients wit...

Markers of gene, protein, or micro-RNA activity predict outcome in prostate and colorectal cancers

New organic substrate

...ed to the crop field. Defibreing the wood To obtain the substrate the same machinery is used for defibreing wood to make paper but, in this case, the fibres obtained are much thicker and longer. Wood fibre for papermaking goes through two or three defibreing processes while FIBRALUR substrate is the r...

Unraveling the viral mechanism

...to study other spherical viruses as soon as he can obtain the computer power to study larger structures. Soon, he said, he hopes to be able to study the interactions of virus and cell more closely. Others who participated in his study include Juan Chang (a current graduate student in the SCBMB Program) and...

Gene thwarts some pathogens, gives access to others, could save crops

...Botrytis is a type of pathogen that can infect and obtain nutrients from dead cells on a plant and actually secretes toxic substances into plant tissue in order to gain entry. Another type of pathogen, called a biotroph, must feed on live plant cells. As a strategy to contain a pathogen, plants actually kil...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

...hondrion then processes acetyl CoA using oxygen to obtain large amounts of ATP. It was already known that during hypoxia, HIF-1 accelerates the output of ATP by glycolysis, Dang noted. But until now researchers thought that HIF-1 simply turned up glycolysis and let the mitochondrion slow down on its own a...

Legume compounds may help cancer treatment

... CILR researchers screened legumes (plants which obtain useable nitrogen from soil bacteria in their roots) for biological activity and they identified a number of compounds which could potentially prevent the formation of a blood supply to tumours. Without an adequate blood supply tumours stop growing an...
