Chongwu Zhou's new method allows for the creation of dense arrays of ultrafine wires made of magnesium oxide coated with uniform, precisely controlled layers of TMO. The technique enables the production of nanocables with extraordinary properties, including high-temperature superconductivity and magnetic applications.
Researchers investigated acamprosate's interactions with alcohol in a six-week study. The findings suggest that acamprosate does not alter the rate of absorption or elimination of alcohol by the body, disrupting effects on performance tasks, or most mood effects. This suggests potential as a medication for treating alcoholism.
A study found that blacks were underrepresented on liver transplant waiting lists, with only 8.4% of the list being black despite 13.6% of the population being black. Blacks also had higher mortality rates while waiting for transplants and were less likely to receive transplants within 4 years compared to whites.
A study published in Alcoholism: Clinical & Experimental Research found that light-to-moderate drinking has no significant effect on breast cancer risk, regardless of type of beverage. Heavy drinking increases risk primarily among premenopausal women.
A mobile testing van was introduced in Zimbabwe's Epworth and Seke areas, offering free rapid HIV tests with same-day results. The initiative reduced structural barriers by providing convenient access to testing and increased acceptance of rapid tests due to same-day results.
A study found that Type A alcoholics who took sertraline showed improved treatment response and maintained gains after treatment ended, while Type B alcoholics did not. In contrast, Type B alcoholics experienced increased heavy drinking after receiving sertraline.
Researchers will investigate safety issues and late-stage effectiveness of retinal cell transplantation in animal models before planning human clinical trials. The goal is to preserve vision in patients with RP who retain a small degree of central vision throughout their life.
A team of scientists has documented a new phenomenon where the seafloor creates a void that sucks in surrounding seawater. This discovery challenges scientific understanding of seafloor spreading and its impact on ocean crust. The researchers believe that the dilation of the ocean crust may lead to changes in water temperatures, chemic...
Researchers from the University of Houston are working on a plasma propulsion system called VASIMR, which aims to improve electric propulsion systems for deep space missions. The team has been studying the physics and engineering behind VASIMR since 1980 and recently received an award for their technical and scientific excellence.
Researchers at Argonne National Laboratory have determined the three-dimensional structure of sortase, an enzyme that attaches proteins to bacterial pathogens. This discovery could lead to the development of new drugs targeting this enzyme, which is essential for bacterial survival and iron acquisition.
HDA (helicase-dependent amplification) is a new DNA copying technique that mimics nature's method of replicating DNA using a helicase enzyme. This approach eliminates the need for thermocycling and expensive equipment, making it suitable for hand-held diagnostic devices.
Researchers at UNC found that 77% of red snapper samples were mislabeled as another species, including lane snapper and vermilion snapper. This widespread mislabeling threatens to distort fish stock estimates and fisheries management.
Italian researchers found a 40% relative reduction in endometriosis risk among women consuming higher amounts of green vegetables and fresh fruit. Conversely, high consumption of beef, other red meat, and ham was associated with an increased risk, potentially leading to a 3-4% decrease in prevalence if confirmed by future studies.
Researchers found that human p53 and Cep-1, a roundworm protein, bind to similar DNA sequences in their respective genomes but in different conformations. The study suggests that both proteins exist primarily as tetramers under normal circumstances, leading to a new understanding of how they interact with DNA.
A multi-site trial found that naltrexone injections significantly reduced drinking days and increased abstinence rates compared to placebo. The depot/injection form of naltrexone offered greater medication compliance, efficacy, and fewer adverse effects.
Researchers found a nematode's oxygen-sensing mechanism can regulate blood pressure. The discovery reveals that worms prefer lower oxygen concentrations, which may explain their unique behavior.
A recent study by researchers at the Gladstone Institute of Virology and Immunology investigated potential superinfection involving variations within HIV-1B. The findings, presented at the XV International AIDS Conference, suggest that superinfection may be restricted to a short window period after seroconversion.
The Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program awards supercomputer processor hours and data storage space to researchers. Successful proposals describe high-impact scientific research and demonstrate the ability to utilize the IBM SP supercomputer's 6,656 processors.
Researchers at Vollum Institute found that dopamine molecules are released from midbrain nerve cells in a targeted manner, traveling to receptors within milliseconds. The study's findings suggest new therapeutic targets for Parkinson's disease and substance abuse.
Researchers at Purdue University are developing a system to continuously monitor heat panels on future spacecraft for subtle damage, which could lead to accidents if left undetected. The system uses vibration and sound measurements to detect damage in real-time, making it ideal for periods of highest stress during takeoff and reentry.
The study's findings suggest that current conservation planning approaches may be hindering species protection. Instead, scientists recommend a more dynamic business plan approach, leveraging market uncertainty and landowner motivation to safeguard habitat for highly threatened species.
OHSU researchers are studying vaccination methods for seniors and children, with a focus on developing protection against infectious diseases. The study aims to understand immune system changes that occur with aging and develop methods to manipulate the system for better protection.
Researchers found that mouse brain stem cells can develop into blood vessel cells, expressing markers associated with endothelial cells. This discovery keeps the possibility open of harnessing adult stem cells from different organs to prevent and treat neurological disorders.
Researchers discovered that a cell death protein, IAP, plays a surprising role in restoring cellular movement in fruit fly ovaries. By studying engineered flies with dysfunctional Rac protein, they found that IAP can compensate for the lack of functional Rac, allowing cells to migrate properly and restore fertility.
Researchers developed a mathematical model that accurately reproduces gypsy moth population outbreaks, combining host-pathogen and predator dynamics. The model resolves the irregular timing of outbreaks and accounts for spatial synchrony, paving the way for applications to other forest insects and small mammals.
