The results of a new study by neurological researchers at Rush University Medical Center show that a sudden decrease of testosterone, the male sex hormone, may cause Parkinson’s like symptoms in male mice.
A team led by William Fenical at Scripps Institution of Oceanography at UC San Diego has discovered a new chemical compound from an ocean microbe in a preliminary research finding that could one day set the stage for new treatments for anthrax and other ailments such as methicillin-resistant Staphylococcus aureus (MRSA).
Chemists from North Carolina State University have performed a DNA-based logic-gate operation within a human cell. The research may pave the way to more complicated computations in live cells, as well as new methods of disease detection and treatment.
Researchers at the University of Arkansas have identified that water, when chilled to a very low temperature, transforms into a new form of liquid.
A normally staid University of Chicago scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. At issue is how numerous small, glassy spherules had become embedded within specimens of the largest class of meteorites—the chondrites.
University of Adelaide research has produced a potential new antibiotic which could help in the battle against bacterial resistance to antibiotics.
A discovery at the University of Wisconsin-Madison may represent a significant advance in the quest to create a "hydrogen economy" that would use this abundant element to store and transfer energy.
Scientists have discovered the role of the membrane protein TonB in bacteria that cause a wide variety of diseases, including typhoid fever, plague, meningitis and dysentery. Results may lead to new and improved human and animal antibiotics.
New research reveals that the likely culprit behind Alzheimer's has a different molecular structure than current drugs' target -- perhaps explaining why current medications produce little improvement in patients.
In the world, there are a lot of small molecules people would like to get rid of, or at least convert to something useful, according to University of Wisconsin-Madison chemist Robert J. Hamers.
A mother's prolonged use of antibacterial soaps containing the chemical triclocarban may harm nursing babies, according to a recent study from the University of Tennessee, Knoxville.
Researchers discover way to use iron as catalyst for widely used chemical process, replacing heavy metals.
Using biochemistry and mass spectrometry, researchers “trapped” scores of new candidate substrates of the protease ClpXP to reveal how protein degradation is critical to cell cycle progression and bacterial development. The new understanding could lead to identifying new antibiotic targets.
University of Delaware chemist Joel Rosenthal and doctoral student John DiMeglio have developed an inexpensive catalyst that uses the electricity generated from solar energy to convert carbon dioxide into synthetic fuels.
In this week’s issue of Nature, scientists at The Scripps Research Institute report their discovery of an important trick that a well-known intrinsically disordered protein uses to expand and control its functionality.
A chemical hormone released in the body as a reaction to stress could be a key trigger of the mechanism for the late onset of Alzheimer’s disease.
Memory improved in mice injected with a small, drug-like molecule discovered by UCSF San Francisco researchers studying how cells respond to biological stress.
In an article published in the Proceedings of the National Academy of Sciences (PNAS) a research team from University of North Carolina at Charlotte announced that they had uncovered a previously unknown surveillance mechanism, known as a DNA damage checkpoint, used by cells to monitor oxidatively damaged DNA. The finding, first-authored by UNC Charlotte biology graduate student Jeremy Willis and undergraduate honors student Yogin Patel, was also co-authored by undergraduate honors student Barry L. Lentz and assistant professor of biology Shan Yan.
Monell researchers identified odorants from human skin cells that can be used to identify melanoma, the deadliest form of skin cancer. In addition a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells. Non-invasive odor analysis may be a valuable technique in the detection and early diagnosis of human melanoma.
Begun over 20 years ago at The University of Alabama in Huntsville (UAH) to study medicinal properties of Costa Rican plants, the Natural Products Drug Discovery Group has branched out to Africa, Australia, the Bahamas, Yemen and Cuba.
