New understanding of regeneration gained by Forsyth scientists

... is the case with planaria where the cells have to decide whether to build a head or a tail, could be due to long-range signaling, which allows the determination of position relative to - and the identity of - remaining tissue. Michael Levin, PhD., Associate Member of the Staff, said, "This research has ...

Many needles, many haystacks

...ike looking at a line of automobiles and trying to decide which one a bulky motor fits into ?versus trying to find where a tiny screw goes. Linear motifs are so small that it is hard to tell what features allow them to bind to other molecules. Now Victor Neduva, a PhD student in Russell's group, has develop...

DNA technique measures suitability of soil for onion crops

...heir individual DNA 'barcode'. The grower can then decide whether or not he wants to grow onions on the plot of land tested. ...

Cheap, rapid hand-held check for HIV

... condition. Doctors rely on CD4+ measurements to decide when to start drug treatments and to gauge whether a patient is responding to them. To make the device, researchers from Cornell University in Ithaca and the University at Albany coated electrodes with antibodies specific to CD4+ cells. When a smal...

...out the following word. Participants either had to decide whether the word referred to something living, or ...bjects had to imagine what the item looked like to decide whether it was taller than wide or vice versa. The cue before each word in this experiment told peop...

K-State researchers study gene regulation in insects

...und not to be needed. "These results will help us decide which genes to investigate in other insects and arthropods to better understand the basic process of segmentation and how it is regulated at the genetic level," Brown said. ...

Scaled-down genome may power up E. coli's ability in lab, industry

Screening blood for West Nile virus

...is one are therefore essential to help politicians decide how to spend their budget wisely.) The analysis, published in the international open-access medical journal PLoS Medicine, revealed that in states with low WNV infection rates, the risk of an infected person donating blood was so low that screening ...

University of Utah to help build bionic arm

...ect leaders at the Applied Physics Laboratory will decide which approach or approaches work best and deserve another two years of funding. The Utah team is focusing on implanting electrode arrays in nerves in the residual limb. "The nerve is potentially an excellent site for communicating with the nervous...

Both alcoholism and chronic smoking can damage the brain's prefrontal cortex

Honeybee decision-making ability rivals any department committee

...chose the excellent site. To test whether the bees decide by quorum or consensus, the researchers: offered swarms two first-rate sites on Appledore Island in the Gulf of Maine, site of Cornell's Shoals Marine Laboratory, both equidistant from the swarm. As soon as about 15 bees were seen at one site, the ...

Why nerve cells work faster than the theory allows

...hich rules, the nerve cells in the cerebral cortex decide to send out impulses. They surprisingly found, that the high flexibility and speed with which these cells work cannot be explained using the present, central model of neurophysiology, the Hodgkin-Huxley model. Their findings suggest that the sodium...

UCLA scientists uncover mechanism of response to targeted therapy

... indicates response to CCI-779. Doctors could then decide on what treatment to use in those likely to respond to the drug. A secondary study finding determined that the drug's efficacy can be monitored quickly using positron emission tomography (PET). Because HIF also regulates glucose transport in cells, ...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

... "Starting from scratch, just trying to rationally decide which two amino acid changes to make on the virus, there is no way you would have guessed those two," Schaffer said. "Using the same algorithm as nature came up with - evolution - to solve the problem, is the best way to do it." Since each generatio...

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

"The test is based on underlying molecular changes involved in cancer development, and this molecular information is complementary to the clinical and a...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

...any given day, and a roll of the dice is needed to decide whether they are infected or not," said Germann. Other elements of randomness modify the simulated disease course. A significant fraction of infected people (33 percent in the present model) never develop clinical symptoms, although they are themsel...

How HIV 'exhausts' killer T cells

...tly, we just count the number of helper T cells to decide when to treat someone, but we are excited about the possibility that adding PD-1 measurement might tell us more about the likelihood of progression of the disease and need for treatment in infected people," he said. Walker said that scientists ...
