Researchers create functioning artificial proteins using nature's rules

...s so close that, at least in a test tube, we can't tell them apart from natural proteins." Dr. Ranganathan said there could still be many small differences between the artificial proteins and the natural ones, and further testing would need to be done to determine whether they work within an actual orga...

Monkeys understand numbers across senses

...ions," Jordan said. "And studies with infants will tell us whether this ability applies to infants before they have acquired language." ...

WCS says avian flu prevention should focus on farms, markets

...ease. Laboratory testing from surviving birds will tell us if they are able to carry the virus during the migration" explained Dr. Karesh. This information will allow countries in the region to protect human and domestic animal health by limiting contact with wild birds and increasing surveillance for the...

New technique could alter field of mouse genetics

...ow many genes are in the genome, but that does not tell us how they carry out their jobs," said senior author Tian Xu, a Howard Hughes Medical Institute (HHMI) investigator at Yale University School of Medicine. "We have found a way to systematically inactivate genes in the mouse genome so we understand t...

Long-sought flower-inducing molecule found

...in the 30-ies scientists found out that plants can tell whether they are growing in spring, summer or fall by measuring the length of the day. One could also show that plants use their leaves to sense the length of the day. By grafting leaves from plants that had been induced to flower on non-induced plan...

DNA from feathers tells tale of eagle fidelity

...re hard to catch, and individuals are difficult to tell apart," Rudnick said. "By performing genetic analysis on feathers collected at the site, we were able to track the presence or absence of individual birds over a six-year period." This kind of monitoring is essential to conserving rare or endangered...

Skull study sheds light on dinosaur diversity

...ient to walk that way. But some sauropod trackways tell us that a group of sauropods were walking with a new wide-gauge stance. We can identify characteristics of titanosaurs that would have allowed that stance, and we can tie the appearance of those features with the proliferation of wide gauge tracks ev...

Purdue researchers find key to rice blast fungus

... unique family of proteins that acts as feelers to tell the fungus when it has a good host plant and how the plant might fight a fungal invasion. These feelers are called G-protein-coupled receptors (GPCR). In humans, GPCRs are found on the tongue and in the nose and are part of what makes foods taste dif...

California computer scientists double volume of data in NIH biotech repository

...how to design the experiment," said Eskin. "We can tell how many individuals' genotypes need to be sequenced - and how many and which SNPs to collect - to minimize the cost and processing power needed for the most effective study correlating genetic data and the incidence of disease." Disease associati...

U-M scientists say fused genes trigger the development of prostate cancer

"We can tell how many individuals' genotypes need to be sequenced - and how many and which SNPs to collect - to minimize the cost and processing power needed for the most effective study correlating genetic data and the incidence of disease." Disease associati...

Study hints at role of stem cell genes in testicular, breast cancers

...of germ cell tumor progression, says Clark, "could tell us something about the potential for these tumors to metastasize." Finally, they examined breast cancer tissue and normal breast tissue. While normal tissue did not express detectable levels of the genes, both the breast carcinoma cell lines and sta...

Cracking the perception code

...cortex, is directly related to monkeys' ability to tell how fast something is vibrating, Romo said. But the neurons' firing patterns are complex, and it's been tricky to tease out "which component of the neuronal activity was more likely associated with behavioral performance," he explained. Theoreticall...

UT Southwestern researchers develop screening test for cells that activate immune system

...t through large numbers of chemicals for ones that tell the dendritic cells to launch the immune response. It may also prove useful in identifying biothreat agents because it detects infectious pathogens with high sensitivity. Dr. Takashima said he hopes to garner additional funding to discover potent i...

Biotechnology's newest chemical tool

...tes to taste, touch, sound, hearing and sight that tell us about the external world. CYBERHAND includes sensors for tension, force, joint angle, end stroke and contact in the final prototype. This prototype uses Longitudinal IntraFascicular Electrodes (LIFEs) to connect the hand to the nervous system. Wi...

Zebrafish may hold key to improved cancer research

...high numbers of possible drug therapies, and might tell you in three months what it would take two years to find out with other animal models." "This low cost, efficient research should speed up drug development, save many millions of dollars and help lead to new cancer therapies." Using zebrafish, OSU h...

The earliest animals had human-like genes

.... "This gives us two independent measurements that tell the same story," Raible explains. "Most introns are very old, and they haven't changed very much in slowly-evolving branches of life, such as vertebrates or annelid worms. This makes vertebrates into something like 'living fossils' in their own right...

A new link between stem cells and tumors

...cules it needs to launch new genetic programs that tell it what to become," says Cayetano Gonz�lez, whose group began the project at EMBL and has continued the work as they moved to the IRBB-PCB. "The current study investigates what happens when the process of localizing these molecules is disturbed." Wh...

Magnetic probe successfully tracks implanted cells in cancer patients

University of Arizona plant scientists to unravel maize genome

...g of state investments. "The genome sequence will tell us which genes we need to focus on to develop corn varieties that produce higher yield and better quality with less water on less land," said Wing, who is a professor in the department of plant sciences at the UA College of Agriculture and Life Scien...

New understanding of regeneration gained by Forsyth scientists
