Affymetrix and ParAllele Launch Industry's Most Comprehensive Product Line for Targeted Genotyping

Twenty-eight years after intense selective logging stopped in the region now known as Uganda's Kibale National Park, the red-tailed guenon (Cercophithecus ascanius) is a primate still in decline. The logging practice, scientists report in a new study, changed the ecological balance for these monkeys, leading...

Logging changed ecological balance for monkeys, damaged health

Twenty-eight years after intense selective logging stopped in the region now known as Uganda's Kibale National Park, the red-tailed guenon (Cercophithecus ascanius) is a primate still in decline. The logging practice, scientists report in a new study, changed the ecological balance for these monkeys, leading...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels

...lanoma and lung cancer. Inhibitors of the integrin stopped new blood vessel growth and suppressed tumor growth, indicating that the integrin helped in the creation of tumors "Our study marks the first time this integrin was found to play a key role in angiogenesis," said Varner. "This integrin is known to r...

Novel live reporting system to track cells

...cells through the administration of TET. When they stopped the TET, the "switch" turned on, triggering ferritin molecules to increase their numbers, thereby causing an increase in iron uptake within the tumor cells. The contrast between the iron content in these and in the normal surrounding cells showed up ...

MIT engineers an anti-cancer smart bomb

...mice. The double-loaded nanocell shrank the tumor, stopped angiogenesis and avoided systemic toxicity much better than other treatment and delivery variations. But it is patient survival and quality of life that really inspire this research, Sasisekharan said. Eighty percent of the nanocell mice survived be...

UN pours polio vaccine into Yemen amid outbreak

...ree countries, such as Yemen and Indonesia, can be stopped quickly, provided high-quality immunization campaigns are implemented rapidly. While these events strain the financial resources of the global eradication effort, they do not threaten its ultimate success," UNICEF said. The Global Polio Eradication ...

Natural Killers Could Lead to New Hepatitis Treatments

...The researchers observed that the roving NKT cells stopped their movement when alerted by a foreign protein, called an antigen, “We think this is a reflection of their normal function of searching for antigen,?said Littman. “Whenever there is detection of antigen reflecting some kind of damage or local infec...

WHO suspends Marburg work, appeals for new funds

International appeal Specialized international staff and equipment have been deployed rapidly and measures are beginning to have an impact. Control of the outbreak will require intensified and sustained techn...

Discovery clarifies role of peptide in biological clock

...posed that knocking out VIP or the receptor for it stopped the clock," Herzog said. "We've found that the biological clock is still running, but its internal synchrony is uncoordinated. This causes irregular patterns of sleep and wake, for example." The study was published on-line in Nature Neuroscience on ...

Elephant seal pups suffer from ocean warming

... After 1999, however, the declining trend abruptly stopped and the weaning weight of the pups increased to eventually reach 130 kg. This change coincided with the cooling of the ocean at the beginning of the new century. "Despite ranging widely and foraging deeply in cold waters beyond coastal thermoclines ...

Used in a new way, RNA interference permanently silences key breast cancer gene

...found 75 percent of laboratory breast cancer cells stopped expressing the STAT3 protein. The researchers also discovered that expression of a protein called TWIST that is known to be involved in cancer metastasis was drastically reduced in the STAT3 knockdown cells, thus greatly reducing the ability of these...

Survey finds silver contamination in North Pacific waters

...igh levels in the 1970s and early 1980s that clams stopped reproducing and some species of invertebrates disappeared from mudflats, he said. At that time, silver concentrations in the bay were 100 times higher than the levels Ranville and Flegal found in the open ocean. With stricter pollution controls, howe...

Birds brains reveal source of songs

...bserved that disabling a young finch's AFP circuit stopped the learning in midstream. The bird still sings, but never learns the right song. To explain this effect, scientists theorized that the AFP circuit helps the juvenile compare its immature efforts with its parent's (usually the father's) example. That...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

...ugs designed to be used for a week or two and then stopped once an infection clears, he said. Now UF researchers have devised a patent-pending method that combines testing of various drug concentrations at the site of infection with a series of laboratory analyses and mathematical models designed to streaml...

New winter hulless barley has high protein

...component of the region's cropping system, growers stopped producing it because it was not profitable. The Small Grains Breeding Program work is aimed at reversing this trend. It has focused on improving and diversifying barley's end-use quality. "Traditional hulled barley cultivars that have higher starch ...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

...ns science team. The rover followed a transect and stopped occasionally to perform detailed surface inspection, effectively creating a "macroscopic quilt" of geologic and biological data in selected 10 by 10 centimeter panels. After the rover departed a region, the ground truth science team collected samples...

Viral protein influences key cell-signaling pathway

...el with an HTLV-1 that lacked the p12 gene, and it stopped the virus from replicating almost entirely. "That told us this gene was important," he says. Subsequent research led by Lairmore showed that the p12 protein travels to the network of membranes within the cell known as the rough endoplasmic reticulu...
