Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice

...nstitute of Genetic Medicine at Johns Hopkins have invented a cost-effective and highly efficient way of analyzing what many have termed "junk" DNA and identified regions critical for controlling gene function. And they have found that these control regions from different species don't have to look alike to w...

'Word-vision' brain area confirmed

...e a piece of neural tissue dedicated to a recently invented cognitive skill like word recognition?" wondered Alex Martin in a preview of the paper in the same issue of Neuron. Nevertheless, Martin commented, Cohen and his colleagues "report a unique set of findings in favor of the existence of the VWFA that w...

'Shuttling' protein possibly key to resilience of cancer cells

... scientists, using an innovative imaging technique invented at Purdue, have learned that a protein previously believed to be confined to the nucleus of healthy cells actually shuttles between the nucleus and cytoplasm, the region of the cell surrounding the nucleus. Moreover, the protein's shuttling is contro...

FDA approves first medical device using rutgers biomaterial

...market." Kohn pointed out that the technology was invented in 1997 and has progressed along a fast and efficient track to FDA approval ?a process that usually takes 10 years or more. The invention was made with initial research support from the National Institutes of Health and demonstrates how a federal ag...

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

...arch platform, a science appliance cluster concept invented at Los Alamos in the Computer and Computational Science Division. Los Alamos has four science appliance clusters in use at this time for a variety of projects across the full range of Laboratory mission areas. ...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

...al leap makes it possible Intravital microscopy, invented in the early 19th century, allows scientists to look at the tissues and cells of live animals. The technology has been in use for generations. But particularly advanced and powerful multi-photon microscopes using infrared beams to image fluorescent c...

New human retrovirus originated in mice

...les, DeRisi and Ganem used the Virochip, which was invented by DeRisi and his colleagues. The Virochip consists of a microarray of some 20,000 characteristic gene sequences -- called oligonucleotides -- representing a vast array of known viruses. The oligonucleotides are deposited as tiny spots on a small gla...

Rice scientists make first nanoscale pH meter

...or using nanoshells, optically tuned nanoparticles invented by Halas. Each nanoshell contains a tiny core of non-conducting silica that's covered by a thin shell of metal, usually gold. Many times smaller than living cells, nanoshells can be produced with great precision and the metal shells can be tuned to a...

Use of stone hammers sheds light on geographic patterns of chimpanzee tool use

...t to the east of the river because it had not been invented there. The new finding that chimpanzees crack open...tively, it may indicate that nut-cracking has been invented on more than one occasion in widely separated populations. This is one of the first reports of too...

Prion find points way to test for human 'mad cow' disease

...as protein misfolding cyclic amplification (PMCA), invented by Soto's group, which greatly accelerates the process by which prions convert normal proteins to misshapen infectious forms. "With this method, for the first time we have detected prions in what we call the silent phase of infection, which in human...

Columbia University licenses next-generation DNA sequencing technology

...Inc. This innovative DNA-sequencing technology was invented by Dr. Jingyue Ju, professor of Chemical Engineering and head of DNA Sequencing and Chemical Biology at the Judith P. Sulzberger, M.D. Columbia Genome Center at Columbia University. The fundamentals of this new technology are being published on-line ...

Taking 'chips' to the next level of gene hunting

...Johns Hopkins' High Throughput Biology Center have invented two new gene "chip" technologies that can be used to help identify otherwise elusive disease-causing mutations in the 97 percent of the genome long believed to be "junk." A variety of DNA microarray technology, one of the two new chips, called the T...

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

... cookware. Now, a University of Minnesota team has invented a "reactive flash volatilization process" that hea... attention in February 2004, when a team he headed invented a similar apparatus to produce hydrogen from ethanol. ...

MIT: Pulsing light silences overactive neurons

Scientists at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease. Such diseases often must be treated by removing ...

Microfluidic chip helps solve cellular mating puzzle

...proceed as smoothly." The microfluidic chip was invented and patented by a team that included Levchenko and Paliwal, who teamed up with Alex Groisman, a physicist from the University of California, San Diego. In place of the microscopic electrical circuitry of a computer chip, their device consists of a se...

Walking molecule now carries packages

...this research is still in its infancy. "In 2005 we invented the molecular walker, which moves in a straight line rather than hopping around in all directions as a normal molecule would do. Now it can carry a load." Bartels said the continuing evolutionary process will take some time. "Ten years ago, a ce...

The origin of the brain lies in a worm

... "Such a complex arrangement caould not have been invented twice throughout evolution, it must be the same system," adds Gáspár Jékely, a researcher from Arendt's lab, who contributed essentially to the study. "It looks like Platynereis and vertebrates have inherited the organisation of their CNS from their ...

Cancer-killing invention also harvests stem cells

...of Rochester Biomedical Engineering Department has invented a device that filters the blood for cancer and stem cells. When he captures cancer cells, he kills them. When he captures stem cells, he harvests them for later use in tissue engineering, bone marrow transplants, and other applications that treat h...

Students invent protective pouch to enhance cell therapy

Johns Hopkins undergraduates have invented a device to improve cell therapy for diabetes patients by anchoring transplanted insulin-producing cells inside a major blood vessel. A team of five seniors and two freshmen, working with Johns Hopkins doctors and engineers, devised a protective "p...

Simple home spit test to spot deadly pre-eclampsia

...ired hospital rheumatologist Brian Owen-Smith, who invented the test. The trial, which will eventually involve 1000 women, is underway at St Richards Hospital in Chichester. Trial subjects send away saliva-wiped swabs for analysis. Results are expected early next year. The ultimate aim is to develop a "tra...
