Water management in cells

...s in and around the cell. Exactly how this process works is still not known. Bas Tomassen has identified a number of important mechanisms that play a role in this process. Increasing the salt concentration in the cell or decreasing the salt concentration around the cell leads to an influx of water. This ...

Enzyme affects hypertension by controlling salt levels in body

...nd that SGK1 was one of those proteins. Because he works on ion channels, including sodium channels, Dr. Huang joined efforts with Dr. Cobb to study how WNK1 regulates sodium channels. "We have been working on WNK1 for several years now and these findings are unexpected from initial studies," said Dr. Cob...

Green diesel: New process makes liquid transportation fuel from plants

...d of carbohydrates. Because the UW-Madison process works with a range of carbohydrates, a wide range of plants, and more parts of the plant, can be consumed to make fuel. "The current delivered cost of biomass is comparable or even cheaper than petroleum-based feedstock on an energy basis," Huber says. "...

Making plant cells work like miniature factories

...o-Laboratory on the ISU campus. Mass spectrometry works by measuring the mass of individual ions ?molecules that have been electrically charged. Plant material is ionized into a gas, sorted in an analyzer chamber according to the mass-to-charge ratios, and collected by an ion detector. The detector conver...

Drugs from the deep blue

...essure and heart disease. Pessah's research group works with calcium channel modulators and other biomolecules derived from plants and scorpion venom. But when Pessah and Molinski got to talking at a party some years ago, they quickly realized that they could apply the same methods to screen 124 sponges t...

Survey Uncovers Surprising Attitudes Towards HIV Vaccine Research

...se communities to enable us to find a vaccine that works for all populations.?/p> “It is clear that we have a lot of work to do in explaining HIV vaccine research,?adds paper co-author Matthew Murguía, director of the Office of Program Operations and Scientific Information in the NIAID Division of AIDS...

Firefly protein lets researchers monitor molecule linked to cancer

Researchers develop new testing methods for potential monkeypox or smallpox outbreak

...ive area of further investigation." The test even works in cases where infection may not be obvious. For instance, three of eight subjects who had previous smallpox vaccinations failed to show any outward signs of viral infection and had no noticeable disease symptoms. The researchers found this particula...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...iao Gao led the experiment, using a technique that works on a principle similar to a medical CAT scan. First, the researchers freeze an ultrathin layer of buffer with purified ribosomes so quickly that the water has no chance to crystallize and damage the ribosomes. Then, the frozen sample is imaged with ...

UT Southwestern researchers discover master switch in cell death

...ell death ?a beneficial and normal process when it works right, but malignant in a variety of cancers when it malfunctions. The researchers are now examining tissue from cancer patients to try to determine how mutations in the enzyme’s gene may relate to cancer. “We think this gene will really be a hot s...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...s have it. Greater understanding of how photolyase works could one day lead to drugs that help repair UV damage in human DNA. In the online edition of the Proceedings of the National Academy of Sciences, Dongping Zhong and his colleagues report experimental evidence of what scientists have long suspected ...

A 'dimmer switch' for genes

...s together. "Scientists understand how a molecule works in part because we understand the shape or structure," Graves explains. "But what we discovered takes us beyond knowing the structure. Our data were about features that are not fixed in space, but that are flexible and changing." The team used a nuc...

California computer scientists double volume of data in NIH biotech repository

...ing with the entire dbSNP database showed that HAP works well on diverse data sets. "The challenge of analyzing such a large dataset is enormous, since the integration of the different datasets is not a simple task," explained the research scientist. "In particular, different data sets have different chara...

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

"The challenge of analyzing such a large dataset is enormous, since the integration of the different datasets is not a simple task," explained the research scientist. "In particular, different data sets have different chara...

Purdue's gold nanorods brighten future for medical imaging

... of ultra-sensitive medical imaging technique that works by shining a laser through the skin to detect tiny gold nanorods injected into the bloodstream. In tests with mice, the nanorods yielded images nearly 60 times brighter than conventional fluorescent dyes, including rhodamine, commonly used for a wid...

Scientists unpick genetics of first 15 minutes of life

...in sexually reproducing animals," said Dr Karr who works in the Department of Biology and Biochemistry at the University of Bath. "Sperm DNA has to undergo a complete transformation when it arrives in the egg cell so that it can properly join with the female pronucleus to form a new genetically complete t...

Scientists closer to new cancer detection method

... residual cancer in patients after treatment." It works by capitalizing on fluorescent molecules engineered into tiny strands of DNA or RNA. Known as aptamers, the strands act as molecular beacons, corresponding and readily binding to a sought-after substance such as cancer protein. In this case, the ta...

Many cats unaffected by catnip, C&EN reports

... don’t yet have a thorough knowledge of why catnip works in some felines, they generally agree that a cat receives the necessary stimuli from receptors in its nose and mouth, she says. C&EN offers one tip for cat owners: Store catnip in your freezer to preserve its potency. Nepetalactone is volatile a...

Study hints at role of stem cell genes in testicular, breast cancers

... Studies have shown, says Clark, that OCT 4, which works with NANOG to regulate the capacity of cells to specialize, causes dysplatic lesions in the intestines, skin and stomach. "It would be useful to look at NANOG in those places where we know over expression of OCT 4 results in tumor progression," she s...

Researchers use brain scans to predict behavior

Sapir noted that the reward systems' predictive abilities may be damaged or missing in some patients with mental illness, causing these patients to perceive the world as alien and unpredictable. Other areas in...
