Researchers at Purdue University have developed a method to measure pollutants produced by combustion, using laser-induced fluorescence. This technique has the potential to significantly reduce nitric oxide production in next-generation jet engines, designed for lean direct injection.
Researchers at UT Southwestern Medical Center have developed an animal model for human colorectal cancer, which will facilitate research into the molecular mechanisms of the disease. The model, based on a colon cancer mouse, allows for testing of chemoprevention agents and new drug treatments.
In a groundbreaking case, doctors at the University of Maryland Medical Center reversed kidney failure in an HIV-infected patient by putting them on high-intensity antiretroviral therapy. The patient's kidneys regained normal function, and their viral load decreased significantly.
A two-day conference at the AAAS Auditorium will bring together scientists, religious leaders, and corporate representatives to explore global climate change. The event aims to outline scientific evidence and address ethical, religious, and economic challenges related to the issue.
A protein on sperm surfaces is essential for binding to eggs and traveling into the oviduct. Mice without this protein have reduced fertility rates, opening possibilities for new male contraceptives and treatments for infertility.
A computer simulation by Cornell University geologists shows that forest fires follow a fractal distribution, similar to other natural events. By analyzing data from forests and wildfires worldwide, including Yellowstone National Park, the researchers found that allowing smaller fires to burn can prevent larger ones.
Researchers at Berkeley Lab have developed a new technique called MARPE, which directly determines the identity of an atom and its neighbors. The method works by analyzing the energies of electrons emitted when excited by photons, revealing the presence and identity of neighboring atoms.
Recent analysis of Mars data from the Mars Pathfinder Mission suggests that the C1 carbonaceous chondrite standard is incorrect, with Mars exhibiting a distinct elemental composition. This contradicts previous assumptions about the terrestrial planets' formation and density variations.
A clinical trial is underway to investigate whether estrogen can enhance the effects of drugs used to treat Parkinson's patients, who experience a 'roller coaster' effect from daily Levodopa use. The study aims to determine if hormone replacement therapy can improve the effectiveness and duration of Mirapex treatment.
Bacteriorhodopsin, a salt-loving organism's defense mechanism, is grown in space to produce stable crystals, offering new insights into complex membrane proteins and their applications in all-optical computing. The findings may lead to the development of battery-conserving computer displays.
