Researchers detect first P Cygni profile in X-rays, revealing a 4.5-million-mile-per-hour wind from a compact pair of stars. The discovery provides new insights into stellar winds and their role in astrophysics.
The US-funded Mag-train propulsion prototype, Seraphim, uses magnetic repulsion to push a vehicle forward and provide braking. It is expected to decrease environmental degradations and enable high-speed connections between cities in the western suburbs.
Researchers at UC Berkeley found that contract bridge players have increased numbers of immune cells after a game, suggesting a link between brain activity and the immune system. The study suggests that voluntary activities like bridge may help control white blood cell levels to combat disease.
Researchers found that PCNA and CAF-1 proteins work together to establish stably inherited silenced chromatin structures. This discovery sheds light on the mechanisms of gene expression inheritance in cells.
Human herpes virus 8 (HHV-8) is linked to Kaposi's sarcoma, a cancer often seen in people with compromised immune systems. Deep kissing and amyl nitrite use are risk factors for infection, according to a study published in the New England Journal of Medicine.
Researchers have developed diode-laser-based sensors to measure the properties of gases in industrial processes, such as monitoring combustion, propulsion, and air quality. The technology has shown promising results in detecting carbon monoxide emissions from cars and measuring ammonia densities with high accuracy.
Researchers at UIC successfully synthesized the rare molecule laulimalide, a potent anticancer compound with potential to surpass existing cancer drug Taxol. The stepwise synthesis allows for control of stereochemistry, enabling testing of variants with enhanced antitumor activity.
Researchers developed a new FISH-based method for detecting recurring bladder cancer, showing improved accuracy compared to urine cytology. The test detected high-grade cancers with over 95% accuracy and recurrence up to three months earlier than traditional methods.
Researchers at UCLA and Cambridge report a breakthrough in pain medicine that delivers painkillers directly to affected areas, eliminating unwanted side effects. A single injection of the new medication can alleviate pain for several days, offering a significant improvement over current treatments.
A fragment of a brain growth protein has been isolated that nurtures brain cells, potentially preventing loss of brain function caused by Alzheimer's disease. The fragment acts through mechanisms similar to its larger parent protein and has shown promise in maintaining nerve cell health.
A new gene therapy technique using stents with DNA delivery has shown promise in animal studies for treating coronary artery disease. The method uses a biodegradable film to release genes into cells on the artery wall, inhibiting cell growth and potentially preventing further damage.
A team of archaeologists led by Dr. Clark Erickson discovered a unique landscape-scale fishery operated by pre-Columbian native peoples in the Baures region of Bolivia. The ancient earthworks, built around 300 years ago, provided intensive aquaculture allowing for sustainable food production.
Researchers have identified four brain areas that are active in mouse mothers who exhibit aggressive behavior towards males, but not in non-aggressive females. This finding is an important step towards understanding the origins of maternal aggression and potentially informing strategies for reducing aggression in humans.
Researchers at Stanford University have developed a system to produce single photons 86% of the time, making it easier to detect intruders and ensure secure communications. This achievement takes cyberspace closer to quantum-secured information transfer.
Scientists have discovered genetic mutations causing hereditary lymphedema-distichiasis, a condition characterized by severe fluid retention and double rows of eyelashes. The FOXC2 gene on chromosome 16 is responsible for the mutations, which can also lead to heart defects, spinal abnormalities, and cleft palate.
