Oceans turning to acid from rise in CO2

...'d like to see how they calculated that, and their standard error - but as with the last article, don't panic just yet! Still, if it's a real trend, it could be alarming. Oceans are quite big... It takes a lot of acid to change its pH, I guess! A report issued by the Royal Society in the U.K. sounds the ala...

California computer scientists double volume of data in NIH biotech repository

...eposited in NCBI's dbSNP database. Rather than use standard methods for inferring haplotypes, the computer scientists used HAP, a software tool originally developed at ICSI by Halperin and Richard Karp in collaboration with Eskin. They ran the HAP algorithm on all dbSNP data sets using a cluster of 30 Inte...

U-M scientists say fused genes trigger the development of prostate cancer

Dendritic cells offer new therapeutic target for drugs to treat MS and other autoimmune disease

...m cell often ignored in favor of T-cell targets in standard therapies. FLT3, which controls the development of healthy blood cells, was identified as a treatment target in patients with acute myeloid leukemia, a blood cell cancer, several years ago by the same Johns Hopkins investigators. In the current wor...

Researchers find Amchitka seafood safe for now

...ides were "far below" any human health food safety standard and were similar to levels found in other marine sites in the Northern Hemisphere. Further, the levels in these organisms are lower now than they were immediately following the nuclear test shots. These biological analyses may now form a baseline for...

Amphetamines reverse Parkinson's disease symptoms in mice

...f the dopamine precursor, L-DOPA, remains the gold standard for Parkinson's treatment, said Tatyana Sotnikova, Ph.D., of Duke. However, the efficacy of the therapy wanes with time, and patients often develop fluctuations in motor performance and other adverse reactions. In the current study, the researchers ...

Cracking the perception code

...ere correct, they were rewarded with a treat. The standard stimulus that the scientists trained the monkeys to respond to lasted 500 milliseconds (half a second). They found that when they used a stimulus that lasted 750 milliseconds instead, the monkeys consistently thought the probe was vibrating with a hi...

Minimally Invasive Cancer Treatments Highlighted

...ble pain that is unrelieved by narcotics and other standard pain treatments. These treatments could benefit many of the 100,000 people who develop bone metastasis in the United States each year. Heating (RFA) or freezing (cryoplasty) the tumor kills the tumor and nerve endings in the vicinity of the metastasi...

Biotechnology's newest chemical tool

... predicts that DNA methyltranferases will become a standard laboratory tool like restriction endonucleases. Earlier studies had suggested that the transfer of chemical groups larger than a methyl group would not be possible, in part because replacing AdoMet's methyl group lowered the chemical reactivity of t...

Fresh water affected by salt from deicing roads

... northeastern U.S. already exceeds the recommended standard for the protection of aquatic life of 250 mg/l of chloride. In developed areas of Baltimore, chloride concentrations were already high enough to induce mortality in aquatic animals and alter wetland plant composition. During the winter months chlor...

Student scientists create living bacterial photographs

...ly engineered E. coli growing in dishes of agar, a standard jello-like growth medium for bacteria. Like pixels on a computer screen switching between white and black, each bacterium either produced black pigment or didn't, based on whether it was growing in a light or dark place in the dish. The resulting i...

Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds

... in humans. In the upcoming paper Bertoni used a standard gene therapy method to introduce two genes - dystrophin and a gene that makes a glowing protein - into mice with a mouse version of muscular dystrophy. She found that in mice producing insufficient dystrophin, she could see the glowing protein slowly...

'Acid rain' and forest mass: Another perspective

...e were taken and analysed chemically, according to standard protocols. The location of parcels was carried out as a function of their distance from different foci of emission of contaminants. A flow equilibrium model for the canopy was drawn up together with a generalised micrometeorological model in order to...

Marine conservation organizations team up to conduct Indonesia coral reefs assessment

...nderwater slate. The Reef Check survey is the only standard method used to survey the world's reefs. Initial surveys in the region conducted by Reef Check and other marine conservation organizations have revealed varying levels of reef damage, with some reefs being entirely uplifted out of the sea and destroy...

Brain activity related to processing faces is similar in people with, without autism

Unlike standard MRI scans that show anatomical structures in black and white, fMRI offers digitally enhanced color images of brain function, depicting localized changes in blood flow and oxygenation. When particular regions of the brain increase their neural activ...

Mining biotech's data mother lode

... establish what proteins become encoded. This uses standard techniques.A second analysis tool in the suite predicts what possible protein-protein interactions are taking place. This is novel. When a gene encodes a protein, the protein folds up into a unique shape, forming a 3D structure. This structure can on...

Penn Surgeons Use Completely Robotic Surgery to Successfully Treat Prostate Cancer

A New Era of Hope for the World's Most Neglected Diseases

...on stage. Assuming there is sufficient funding, at standard attrition rates these projects would be expected to deliver eight or nine new neglected-disease drugs within the next five years. “The post-2000 renewal of neglected-disease R&D activity is good news for patients with neglected diseases,?writes M...

Compound from marine bacteria shows potential as multiple myeloma therapy

... from patients whose disease was resistant to both standard drugs and bortezomib, the compound efficiently killed the cells. Analyses showed that NPI-0052 and bortezomib express different profiles for inhibiting the three major proteasome activities. In mice implanted with human myeloma tumor cells, NPI-0052...
