NJIT engineer poised to take stem cell research a step forward

... Technology, will allow her to apply her stem cell techniques to help patients who have cartilage damage. She and Jaffe will spur cartilage regeneration by combing stem cells with bio-degradable scaffolds that mimic fibers found in human cartilage tissue. They will test different scaffolds and determine which b...

World first research to speed up cure for ear infections

...m heals itself we can help clinicians identify new techniques to speed up the healing process for sufferers of ear infections. "Ear infections are a major worldwide health problem and it is common for an average person to take up to 10 years before they receive medical treatment. "We tend to ignore ear infect...

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria

...ria from the immune system of their host. Previous techniques for studying the sugars were too slow to catch these rapid changes. "There's a growing recognition of the importance of carbohydrates on bacterial cell surfaces," says Dr. Lara Mahal, lead researcher and assistant professor of chemistry and bioche...

Molecule by molecule, new assay shows real-time gene activity

...ing cells. Finally, the low sensitivity of current techniques for detecting gene expression has restricted analysis to highly expressed genes. Xie's new assay addresses all three limitations. He and his colleagues melded a yellow fluorescent protein called Venus with Tsr, a hydrophobic membrane protein. The in...

UF researchers develop ways to keep the bloom on the rose

...se life by three or more days through post-harvest techniques so consumers see a difference in the flowers they purchase ?not only on Valentine's Day but throughout the year. "Our research has shown that keeping flowers cold as they move from the field to the florist is critical," said Terril Nell, who has bee...

Removing DNA repair gene causes metabolic syndrome

...e stress to the cells that damages their DNA. Such techniques could one day become therapies. "One may be able to develop a diagnostic method to do early screening," Lloyd said. "Or there could be a drug discovery mechanism in which you enhance the transcription process (of NEIL1) and just make more. Maybe you...

Mice lacking social memory molecule take bullying in stride

...a kind of molecular magic bullet (using transgenic techniques and a virus) that selectively turned off BDNF expression in the social learning circuit. This exerted an antidepressant-like effect; the mice were spared from developing social avoidance behavior following repeated social defeat. "Without BDNF in ...

The giant protein titin helps build muscles

...assembly. The Gautel lab used advanced microscope techniques to watch the molecules link to each other in live cells. "We knew that telethonin acted as a sort of 'cap' or 'bolt' at the end of the titin molecule," Gautel says. "What we couldn't see is how it connected two separate copies of titin together. That...

Oops! Researchers publish new findings on the brain's response to costly mistakes

...at is placed on the head. The method is similar to techniques used to study the brains of people with epilepsy or sleep problems, but the electrical signal from the brain is processed in a different way. In prior studies, Gehring and his colleagues observed a distinct brain electrical response to errors, dubbin...

Strawberries by design

...neva, New York, who has developed highly efficient techniques for transforming apple, remarked: "The commercial strawberry familiar to most consumers is octoploid, which means that it contains eight sets of chromosomes. By using a close relative that has two sets of chromosomes and a significantly smaller genom...

Outsmarting the smartie bug

... known strains will help in the development of new techniques for monitoring changes in capsule type so researchers can look out for such capsule switching. "The new vaccine that will be given to UK children is very effective at protecting against serious pneumococcal disease, but it does not protect against d...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

... them more virulent, he said that other and easier techniques already allow this frightening possibility. AAV consists of two genes enclosed within a ball, or capsid, of proteins. The capsid proteins are what antibodies recognize, and as a result were the target of directed evolution. To provide the raw materi...

Researchers discover way to transport environmental arsenic to plant leaves in new clean-up strategy

...ty of Georgia had, several years ago, used genetic techniques to create "arsenic-eating" plants that could be planted on polluted sites. There was a problem, however. The arsenic sequestered from soil remained largely in the roots of the plant, making it difficult to harvest for safe disposal. Now, the researc...

But doubling the productivity of energy crops will mean identifying constraints and correcting them with genomic tools. To make biofuels a truly practical alternative to pe...

Possible brain hormone may unlock mystery of hibernation

... instead uses the same kind of pattern recognition techniques to distinguish between people as it uses to search for differences between other groups of objects, such as plants, animals and cars. The study, published in the April 6 edition of the journal Neuron, adds new evidence to the debate over how the br...
