Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...ous energy levels. "There are only a handful of laboratories in the world where these kinds of high-energy particles can be produced," Britten said. His team will be work closely with scientists at Brookhaven National Laboratory in New York. As part of his $1.2-million segment of the study, the EVMS team wil...

MIT designs portable 'lab on a chip'

...evolution in computing, the idea is that miniature laboratories of fluid being pumped from one channel to another, with reactions going on here and there, can revolutionize biology and chemistry," says Martin Bazant, associate professor of applied mathematics and leader of the research team. Within the lab on a...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...ng disease, the virus still exists in two approved laboratories in the United States and Russia. The Centers for Disease Control and Prevention classifies it as a "Category A" agent, presenting the greatest potential threat for harming public health if developed and used as a bioterrorist agent. Smallpox is ca...

Lab-on-a-chip could speed up treatment of drug-resistant pneumonia

Paper: "Microfluidic Devices That Capture Bacteria for Growth and Kill Analysis," Tuesday, November 14, 2006, 9:40am, Room 2001, AVS 53rd International Symposium & Exhibition, San Francisco, CA, abstract at http://www.avssympos...

Scientists win grants to develop $1,000 genome sequencing technology

...is currently being done in large genome-sequencing laboratories down to a glass slide the size of a business card. Huang's team will combine micro- and nano-fabrication technologies with innovative chemistry technologies to simultaneously sequence more than 1 billion individual pieces of DNA attached to the surfa...

Powerful genome ID method extended to humans

...ch a high level of expertise that only a couple of laboratories in the world use the method. The Waterman group's algorithm may encourage others to take a second look. ...

Engineered yeast speeds ethanol production

... led by Hal Alper, a postdoctoral associate in the laboratories of MIT chemical engineering professor Gregory Stephanopoulos and Whitehead Member Gerald Fink, took a new approach. The team targeted two proteins that belong to a class of proteins called transcription factors. These proteins typically control l...

Researchers identify a key regulator for skin stem cells

...pected to be. They also knew from studies in other laboratories that a relative of Tcf3, called Tcf4, appears to be important for the development of the intestine. The researchers reasoned that if Tcf3 plays a role in maintaining adult follicle cells, it would also be present in embryonic skin, which consists ...

A valuable fly for research into disease

... auditory and immune systems. A growing number of laboratories are modelling human diseases in the fly. These models are providing the basic tools for genetic and pharmacological tests that aim to identify target genes as well as compounds that may lead to future therapies. Moreover, more and more companies that...

MRSA toxin acquitted: Study clears suspected key to severe bacterial illness

...routinely receive calls from clinical microbiology laboratories asking to test for the presence of PVL, and it is hard to dissuade them that the PVL results will not affect patient care. Hopefully, the robust and contrary findings in our study provide the experimental evidence to convince the staphylococcal resea...

NYU scientists identify how development of different species uses same genes with distinct features

...rs in Professor Claude Desplan’s and Steve Small’s laboratories in NYU’s Center for Developmental Genetics, offer new insight into the workings of developmental pathways across species. The study is published in the latest issue of the journal Science. The researchers examined the fruit fly Drosophila and the wa...

'Hidden-hero' microbes in soil, water may help naturally clean toxic sites

...ms from FSU and multiple universities and national laboratories across the country. Together, the partners will develop models to help predict the rate at which contamination levels drop when using natural methods such as bioremediation and artificial techniques such as chemical additions and pH adjustments. S...

Nanoparticles can track cells deep within living organisms

...after being injected into mice. Developed in the laboratories of Samuel A. Wickline, M.D., and Gregory Lanza, M.D., Ph.D., the nanoparticles could soon allow researchers and physicians to directly track cells used in medical treatments using unique signatures from the ingested nanoparticle beacons. In an ar...

Pregnancy hormone key to repairing nerve cell damage

...entral nervous system. A collaboration between the laboratories of Drs. Samuel Weiss and V. Wee Yong of the Hotchkiss Brain Institute, the study is the first to determine that prolactin, which increases in the body during pregnancy, is directly responsible for the formation of new myelin in the brains and spinal ...

Tiny clue reveals new path toward heart disease

...hile being examined at the cardiac catheterization laboratories at Duke University Hospital. Using these DNA samples, the researchers scanned the same small section of chromosome 3 for SNPs that differed in sequence between individuals with and without coronary heart disease. One SNP, in the kalirin gene, var...

Flavanols in cocoa may offer benefits to the brain

... “This research is impressive in that multiple laboratories are coming to the same conclusion about this flavanol-rich cocoa, and the findings give us completely new insights into how this flavanol-rich cocoa may impact health in a variety of ways not previously known,?said symposium organizer Harold H. Schmi...

Homing pigeons get their bearings from their beaks

...ons in collaboration with HASYLAB, the synchrotron laboratories based in Hamburg, Germany, iron-containing subcellular particles of maghemite and magnetite were found in sensory dendrites² of the skin lining the upper beak of homing pigeons. This research project found that these dendrites are arranged in a comp...

Misclassified for centuries, medicinal leeches found to be 3 distinct species

...es supplied by commercial providers and university laboratories that use leeches as model organisms. Their analysis clearly showed that the commercial and laboratory specimens were not Hirudo medicinalis, as they were labeled, but Hirudo verbana. In addition, the work showed that the specimens of wild European...

Genetic fingerprints identify brain tumors' origins

... unexplained. In the new study, Gutmann led six laboratories in the most detailed genetic analysis of PAs to date. "We were hoping to identify genes that contribute to the formation of these tumors and find indicators that might help us predict which tumors will be relatively well-behaved and which will be ...
