New technique rapidly detects illness-causing bacteria

... Technicians take a piece of DNA from a sample and add enzymes that make many copies of the DNA. Duplicating or "amplifying" the DNA makes a pathogen easier to detect. The new process starts with genetic material that is extracted from a food sample. This material, called ribosomal RNA (rRNA), is respon...

Gene Bridges And Covalys To Develop Restriction-Enzyme-Free SNAP-tag Gene Fusion Kits

... combined products will allow scientists to easily add the SNAP-tag gene onto any cloned gene, at any position, so that the SNAP-tag can be used to study protein function and interaction. The cloning kits will be particularly useful for cloning with BACs (bacterial artificial chromosomes) and other large...

Millennium Ecosystem Assessment: Many of 2 billion dryland dwellers at risk as land degrades

... and creating environmental refugees who can often add stress to areas that may not be degraded. Desertification has other strong adverse impacts on non-drylands as well. In addition to dust storms, biophysical impacts include downstream flooding, impairment of global carbon sequestration capacity, and ...

More animals join the learning circle

...eparate studies of feeding behaviour. The findings add to evidence that cultural learning is widespread among animals. One study involved killerwhales at Marineland in Niagara Falls in Ontario, Canada. An inventive male devised a brand new way to catch birds, and passed the strategy on to his tank-mate...

Scientists at Galileo Pharmaceuticals confirm inflammatory response linked to glucose levels

... and genetic basis of the disease are beginning to add up and can be harnessed for treatments." Alzheimer's involves a complicated, interwoven series of regulatory steps of genes and proteins "talking" to each other, he explained. "When the conversation goes awry the disease process begins. And it is no...

Bad aftertaste? New sensory on/off switch may 'cure' bane of artificial sweetener search

...ith visible light, the researchers are now able to add a luminescent tag that glows in the presence of ultra violet (UV) light. "The UV light does not activate the system but will allow us to see such things as how the assembly enters cells and how much of the drug reaches the DNA," Brewer said. "It is a...

Caloric restriction won't dramatically extend life span in humans: UCLA research

Severely restricting calories over decades may add a few years to a human life span, but will not enable humans to live to 125 and beyond, as many have speculated, evolutionary biologists report. "Our message is that suffering years of misery to remain super-skinny is not going to have a big payoff ...

Study: Well-known protein helps stem cells become secretory cells

...lease, or how any gland does, and the new findings add to that knowledge," says Deborah Andrew, Ph.D., professor of cell biology in Johns Hopkins' Institute for Basic Biomedical Sciences. Curiosity brought Andrew and Elliott Abrams, then a graduate student, to focus on secretion in the salivary gland, t...

Moffitt-USF head toward first human trials of anti-cancer drug that targets protein AKT

...previously discredited anti-cancer drug that could add another weapon in the arsenal against several cancers, including tumors of the breast, ovary, colon, skin and prostate. The compound, tricirbine, was tested at various cancer centers from 1982 to 1996 and found to inhibit some cancers, but researche...

Team Invents Device For Weighing Individual Molecules

...e is cooled, the molecules condense on the bar and add their mass to it, thereby lowering its frequency. In other words, the mechanical vibrations of the now slightly-more-massive nanodevice become slightly lower in frequency--just as thicker, heavier strings on an instrument sound notes that are lower t...

Unique library of plant genes germinates, takes root at UNC

"Perhaps the most important will be the ability to compare the genetic maps of multiple species simultaneously and predict the gene content in regions of plant genomes that have not yet b...

Tsunami-damaged coral reefs should be left to recover naturally, say scientists

... reefs will not recover naturally this time. They add that Governments should be very careful not to commit funds to costly repair programmes that may have little long-term effect. About 20 per cent of the coral reefs in places such as Thailand and Sri Lanka were badly affected by the tsunami that happ...
