...ses approximately US$61 billion a year. That price tag includes US$24.6 billion for direct health care of Alzheimer's patients and US$36.5 billion to cover costs related to caregivers of AD patients, including lost productivity, absenteeism and worker replacement. ...

Record bonefish

... ?while he was vacationing in the Bahamas. "The tag number revealed that this bonefish was originally tagged at Bear Cut near Key Biscayne on Feb. 11, 2005, by Capt. Joe Gonzalez," said Dr. Jerry Ault, associate professor of marine biology and fisheries at the UM Rosenstiel School. "That means the fi...

UCR researchers design chip that can improve citrus varieties

...ue, make a copy of these molecules with a chemical tag added, and then "wash" the chip with the RNA sample. If a gene is being expressed in the tissue, its corresponding RNA will be present and bind to the complementary DNA sequences on the chip. The locations of the bound RNA have a visible signal becau...

New method for identifying microbes

Scientist warns of threat to last stronghold of endangered turtle

... dwindle precariously. It's hoped the project, to tag and track the animals, will uncover their migratory secrets and provide the basis for efforts to safeguard them. After fitting them with satellite trackers the team are using the internet to follow their journeys, which are among the longest in the a...

New insight into machinery of immune cells' 'tentacles'

...cells, said Pendergast. Using tracer molecules to tag the proteins in T cells, the researchers found that both Abi and Wave homed in on sites of actin filament formation. What's more, when the scientists activated T cells with a "superantigen," they detected Abi at the contacts between T cells and B cel...

Sea coral's trick helps scientists tag proteins

...t generates the light to create a tiny fluorescent tag that responds to visible light. The two-color tag should help researchers follow individual proteins as they dart around inside living cells. Under a...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...ey Bay, as did the bait fish. We were only able to tag three male sea lions that year, and they went much farther off shore than usual to find food. They've always been described as a strictly coastal species, but they went as far out as 300 miles from the coast," he said. At the same time, Costa's grou...

DNA self-assembly used to mass-produce patterned nanostructures

...turn bind to a protein molecule to give the tile a tag visible by AFM. Each arm of the cross, about 10 nanometers long, had a pair of "sticky ends" where the DNA strand was made of up of unpaired bases that tend to bind with reciprocal bases. Tiles with complementary sticky ends link together when mixed....

Magnetic probe successfully tracks implanted cells in cancer patients

...needle, and dendritic cells carrying a radioactive tag are sometimes used to try to double-check the cells' final resting place. However, in this study, the Dutch team discovered that using MRI and iron oxide particles was able to track the cells' location much more accurately than the radioactive track...

Retinal scans eyed for New Mexico show cattle

...ince May, only two have been lost. Using a panel tag reader located on a cattle chute, researchers found that the RFID tags could be readily read as cattle passed through a single-file alley. Effective range for this particular electronic reader was about two feet. "A prime goal was not to slow down ...

Gene discovery sheds light on causes of rare disease, cancer

...s with Met, the cell responds by adding a chemical tag to Met that flags it for protein recycling or degradation. Since Met is on the outside surface of the cell and the recycling and degradation machineries are inside, the cell must bring Met inside through endocytosis in order to dispose of it. As the ...
