Hot, ionized gas streams toward the galactic center, bending sharply around it and slingshoting out the other side due to its high velocity. The findings may provide clues to the nature of the mysterious black hole candidate.
The Mechanics of Granular Materials (MGM) experiment aims to expand investigations into soil mechanics started on STS-79 in 1996. The new flight will run twice as many tests under various experimental conditions, providing insights into the behavior of soils under low-confining pressures.
New York-based medical schools are developing a statewide approach to address inadequate attention to emotional and ethical issues surrounding end-of-life care. A committee will be appointed to design recommendations for all schools, building on existing efforts by individual institutions.
The Vegetarian Diet Pyramid offers a well-balanced ovo-lacto vegetarian diet plan emphasizing fruits, vegetables, whole grains, and legumes. The pyramid recommends daily exercise and water intake, while optional foods include eggs and sweets.
A study found that genetic variations in apolipoprotein E, specifically the e4 allele, are associated with an increased risk of intracerebral hemorrhage (ICH) in African Americans. ICH occurs at a younger age among African Americans compared to Caucasians, suggesting a possible genetic link.
Astronomers use Hubble Space Telescope images and a computer model to study the behavior of stars in their infancy, shedding light on how cosmic dust influences the environment. The findings provide new insights into the formation of solar systems and the role of powerful jets of dust and gas in shaping star formation.
Researchers use exploratory analysis of CCEP database to identify smaller groups with common health conditions based on shared exposure to risk factors. The study found no large group affected by a syndrome, but identified specific characteristics that may be related to Gulf War Syndrome.
Researchers from UD and Denmark confirmed Subramanyan Chandresekhar's theory on the structure of compact stars, including pulsars, black holes, and white dwarf stars. By analyzing distances to a dozen white dwarf stars using HIPPARCOS data, they verified the theory, which predicts the size of white dwarf stars based on their mass.
Harvard and UF researchers identified a component of the human immune system that appears to prevent type 1 diabetes in a group of people at high risk. The protein interleukin-4 (IL-4) is produced in large amounts in these individuals and may suppress the arm of the immune system involved in the destruction of insulin-producing cells.
A team of astronomers led by Eric Neilsen discovered that a large galaxy is stripping star clusters from neighboring galaxies. The study used data from the Hubble Space Telescope to confirm that globular clusters were stripped away by M87, a giant elliptical galaxy.
A team of internationally renowned scientists returns from a month-long deep sea scientific expedition off the coast of Cuba, discovering four brand new species and 26 previously unknown fish. The expedition used advanced technology to explore coral reefs and shipwrecks, shedding light on underwater conservation.
Researchers at Berkeley Lab create cells with engineered surface properties using unnatural sugars, enabling control over cell adhesion to synthetic materials. This technology has potential applications in biocompatible materials, artificial organs, and cancer diagnosis and treatment.
The study uses satellite technology to track the flight paths of albatrosses in Hawaii, providing insights into their reproduction and population dynamics. The project aims to answer basic science questions and engage students in pre-college education, ultimately contributing to the conservation of these endangered species.
The 191st AAS meeting will feature a lecture on the latest research on gamma-ray bursts, revealing their origin from distant reaches of the universe. Dr. Chryssa Kouveliotou and Sir Martin Rees will present new findings on GRB characteristics, including temporal, spectral, and spatial analysis.
A task force of scientists concludes that smoked foods sold in the US are virtually safe due to limitations in epidemiological studies. The researchers suggest other factors may cause correlations between cured meats and childhood cancers, such as diet composition.
A new study of 667 children at risk of abuse or neglect found that those with strong social support from family, neighbors, and church were less likely to face developmental problems. Church membership, neighborhood support, and personal perception of support all showed significant correlations.
Researchers at Thomas Jefferson University are conducting a gene therapy trial for glioblastoma, a form of brain cancer. The trial aims to delay disease progression and improve quality of life for patients, offering a potential cure for the deadliest type of brain tumor.
Research found that young people under 45 with sleep apnea require aggressive treatment to reduce hypertension and cardiovascular issues. The study, published in the American Journal of Respiratory and Critical Care Medicine, included subjects aged 20-100 years old.
The American Association for the Advancement of Science (AAAS) has announced the winners of its national science writing awards, recognizing excellence in large and small newspapers, magazines, radio, and television. The winners were selected by independent screening and judging committees consisting of journalists and scientists.
Researchers have successfully grown monomolecular films of a helical polypeptide, poly-gamma-benzyl-L-glutamate, directly from a flat surface. The films exhibit comparable polarization to conventional ferroelectric materials, with potential applications in piezo- and pyroelectric devices.
Scientists have identified the gene responsible for Peutz-Jeghers syndrome, a rare autosomal inherited disease characterized by gastrointestinal polyps and an increased risk of various tumors. Mutations in the STK11 enzyme lead to its loss of function, triggering the development of polyps and cancer.
Purdue researchers have developed a new method for measuring the velocity of moving objects using lasers and semiconductors. By using an electronic strobe to make light appear to stand still, they can capture cleaner signals from moving objects, resulting in more accurate measurements of speed.
Researchers have discovered a unique enzyme in an AIDS-related skin disease virus that protects it from ultraviolet radiation and the immune system. The enzyme, similar to human glutathione peroxidase, neutralizes caustic chemicals made by immune cells to fight infection.
