NHGRI aims to make DNA sequencing faster, more cost effective

... the fundamental, front-end chemistry of massively parallel sequencing-by-synthesis. This method uses the natu...dividual DNA molecules can be sequenced in massive parallel though a process involving cyclic sequencing by ligation, a process where an enzyme is used to join ...

A buffet for early human relatives

... marked by tiny ridges called perikymata. They run parallel to the tooth's crown and represent tooth growth, similar to tree rings. Perikymata are produced under the gums during the animal's juvenile years, when teeth are growing. Each laser sampling vaporized enamel that formed during several months and ...

Robotic whiskers can sense three-dimensional environment

...mension, rotating at their base in a plane roughly parallel to the ground. When the whiskers hit an object, they can be deflected backwards, upwards or downwards by contact with the object. The mechanical bending of the whisker activates many thousands of sensory receptors located in the follicle at the whisk...

Faster, more accurate tuberculosis test developed

... All samples were decontaminated and then used for parallel MODS testing, as well as for two current gold standard TB tests-- the Lowenstein-Jensen culture and automated mycobacterial culture (using the MBBacT system). In order to test the samples using MODS, the researchers observed the cultures under an inv...

Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals

...ed for the Human Genome Project as well as the new parallel pyrosequencing method to clone and insert missing fragmented DNA and create a library of Neanderthal DNA. Unlike the libraries used to sequence the human genome, which contained only human DNA fragments, the Neanderthal DNA library is riddled with ...

Squid-inspired design could mean better handling of underwater vehicles

...he latest model, the team successfully conducted a parallel parking test. 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....

Humpback whales have brain cells also found in humans

...estor of great apes, which would be a rare case of parallel evolution. "In spite of the relative scarcity of information on many cetacean species, it is important to note in this context that sperm whales, killer whales, and certainly humpback whales, exhibit complex social patterns that included intricate...

Insulin receptor stops progression of Alzheimer's disease

...uthors write. Alzheimer's appears to be caused by parallel abnormalities ?impaired insulin signaling and oxidative stress, which is regulated by the genes NOS and NOX. The PPAR agonists treatments target both problems. They preserve the cells regulated by insulin and IGF, and they decrease oxidative stress, ...

Genetic 'roadmap' charts links between drugs and human disease

Plant-cell-produced technologies-cutting edge approach to bringing solutions to the market

...a of biosciences for animal and human health. Two parallel seminars will examine innovative plant-cell technologies and will present the benefit of healthy oils for consumers, agriculture and the food industry. The conference will also explore R&D collaboration under the EU's Seventh Framework Programme ...

Ring-like formations in drying DNA drops could affect hybridization studies

...g droplet in three dimensions. "The DNA alignment parallel to the droplet's edge was counterintuitive," Wong said. "We had expected the DNA to extend along the direction of flow, which was mainly in the radial direction. But, instead of resembling the spokes of a bicycle wheel, the transported DNA resembled ...

Parallel evolution: Proteins do it, too

Wild vs. lab rodent comparison supports hygiene hypothesis

...ch can lead to autoimmune disease," he said. "In a parallel fashion, the IgE in the wild animals is protective because the antibodies bind to parasite antigens, while the same antibodies in laboratory animals would bind to abundant but harmless environmental antigens, leading to allergies to those antigens." ...

Study finds that a woman's chances of having twins can be modified by diet

...others. Twinning rates in these demographic groups parallel the IGF levels. "This study shows for the first time that the chance of having twins is affected by both heredity and environment, or in other words, by both nature and nurture," said Dr. Steinman. These findings are similar to those observed in cow...

"NASA's technology in the walker's harness gave me the stability to do squats and knee raises I could never do before." Physical therapists at Kindred Hospital of Greensboro, N.C., have discovered yet ...

A parallel study in Australia that examines the eucalyptus tree as the foundation species is yielding the same results as the studies on cottonwoods. And Whitham has just returned from South Africa and Borneo in Southeast Asia, where he is planting the seeds fo...

Chewing up a key regulator of fat synthesis keeps mice lean despite a high-fat diet

... which gets rid of the enzyme altogether. "In this parallel pathway, TRB3 serves as a go-between for an enzyme that marks ACC for degradation," says Jose Heredia, a graduate student in Montminy's lab. TRB3 levels in adipose tissue usually rise only during fasting, when ACC should be turned off. Heredia and ...

Mayo Clinic researchers discover cancer cells may move via wave stimulation

Waves occur less often in certain tumor cells, indicating they may play a role in modulating or terminating cancer-promoting signals. Persistent cancer-promoting signals in ...
