Computers to be used to find blueprint for new influenza drug

...ing advanced software to model the way these atoms behave in highly complex interactions, the atomic structure of a suitable drug can be worked out. Using computer modelling in this way can be of great assistance in drug design. Normally drugs are produced by trial and error in a process that can take many...

Molecular machine may lead to new drugs to combat human diseases

...ng the structure can help us engineer molecules to behave better," Golden said. "It's very hard to find targets in cells because cells are organized in ways we still don't fully understand. This crystal structure shows us where the best targets are for modifying genetic defects." The crystal structure of t...

Spider Venom Could Yield Eco-Friendly Insecticides

... the insects have never encountered chemicals that behave like spider toxins, they will most likely lack resistance to bioinsecticides derived from funnel-web venom. Another strategy is to insert a gene for encoding a spider toxin into viruses that are specific to a particular insect genus, or even a small...

Jumping gene helps explain immune system's abilities

...teins. But until now, no jumping gene was known to behave just right. Writingin the Dec. 23 issue of Nature, the researchers show that a jumpinggene called Hermes, still active in the common house fly, createschanges in DNA very much like those created by the process behindantigen recognition."Hermes behav...

UCSD Discovery Shows How Embryonic Stem Cells Perform 'Quality Control' Inspections

Vampire bats keep out of trouble by running

...e common vampire bats of Central and South America behave much more like four-legged terrestrial mammals, in that they like to walk around on the ground; other bat species fumble helplessly when left to walk. But researchers in Cornell's College of Veterinary Medicine have discovered that these bats not onl...

Programmable cells: Engineer turns bacteria into living computers

...g engineered pieces of DNA into cells to make them behave in the same manner as digital circuits. The cells, for example, could be made to perform basic mathematical logic and produce crisp, reliable readouts that are more commonly associated with silicon chips than biological organisms. The new paper appli...

Flocking together: Study shows how animal groups find their way

... results may be useful in understanding how humans behave in crowds and in designing robots that explore remote locations such as the ocean or other planets. "When you see apparently complex behaviors, the mechanisms that coordinate these behaviors may be surprisingly simple and generic," said Iain Couzin,...

Researchers identify protein crucial for survival of Lyme-disease bacterium

...d at genes that affect how the infecting organisms behave once inside a human host. What tends to get ignored, Dr. Norgard said, is the other side of the coin. "This organism has to live half of its life cycle in a tick," he said. "There must be subsets of genes important to its survival there. If it can't...

GeneNotes - A novel information management software for biologists

...It also provides a platform for studying how users behave when they manipulate biological information. The results of such study can lead to innovation of more intelligent human-computer interfaces that greatly shorten the cycle of biology research. ...

To control germs, scientists deploy tiny agents provocateurs

...esearchers because of their stupefying capacity to behave like a "super-organism" that vetoes the normal characteristics of a bacterial cell in favor of new group behaviors. "It's amazing that such simple organisms as bacteria can form these super-colonies that work together in such sophisticated ways," say...

Revolutionary nanotechnology illuminates brain cells at work

...otein. In this study, the cyan and yellow proteins behave as if they move away from one another when the sensor recognizes glutamate. Thus, there is more cyan and less yellow light than in the absence of glutamate. The sensors are encoded by genes and genetic ZIP codes can be used to target the sensors to a...

Researchers find promising cancer-fighting power of synthetic cell-signaling molecule

...nalogs might be even better at making cancer cells behave more normally. Merrill and his collaborators have been studying sphingolipids for more than a decade, having first shown that sphingolipids in food, such as low-fat dairy products and soybeans, suppress tumors in mouse models for colon cancer. Enco...

Alcohol consumption disrupts breastfeeding hormones

...feeding conditions, oxytocin and prolactin usually behave in tandem, such that sucking-induced breast stimulation results in transient release of both. However, following alcohol consumption we saw divergent responses in these two key hormones that control lactation." After consuming alcohol, women took lo...

Atmosphere may cleanse itself better than previously thought

... While many such chemicals have long been known to behave in this way ?producing natural air cleaners called OH radicals ?the chemicals the team studied have for the first time been observed to produce air-scrubbing OH radicals at low ultraviolet wavelengths. This observation has eluded science primarily be...

Tamoxifen-like drug suggests new ways to selectively block estrogen

...understand why drugs like tamoxifen and raloxifene behave the way they do, simulating the effects of estrogen in some tissues and blocking it in others. The finding indicates that this little-known drug may play an important role in preventing, as well as treating, breast cancer and suggests ways to design ...

Vitamin A's paradoxical role in influencing symmetry during embryonic development revealed

...ells in the vicinity of the node are instructed to behave differently depending on whether they are on the left or right sides of the embryo. The action of retinoic acid makes sure that some of those cells ignore the left-right instructions and progress symmetrically. Belmonte compares the node to a doorwa...

MIT engineers an anti-cancer smart bomb

... it there," Sasisekharan said. Also, the two drugs behave differently and are delivered on different schedules: anti-angiogenics over a prolonged period and chemotherapy in cycles. "We designed the nanocell keeping these practical problems in mind," he said. Using ready-made drugs and materials, "we create...
