Astronomers have obtained radar images of a giant, dog bone-shaped asteroid called 216 Kleopatra, located in the main asteroid belt between Mars and Jupiter. The asteroid is about 217 kilometers long and 94 kilometers wide, with a shape that resembles a distorted dumbbell or dog bone.
A study by the American Academy of Neurology found that people with higher levels of non-occupational activities, such as playing a musical instrument or gardening, were less likely to develop Alzheimer's disease later in life. Researchers also discovered that it is never too late to get started with intellectual activities.
Researchers found a link between smoking, coffee consumption, and lower Parkinson's disease incidence. Higher dopamine levels in the brain may explain why people with these habits are less likely to develop Parkinson's.
Researchers used X-ray crystallography to determine the structure of COX-2 with arachidonic acid bound, gaining insights into its interaction with inhibitors. The study's findings may help guide future drug development for pain, inflammation, and cancer treatment.
Researchers created self-assembling ink that forms nanoscopic pores with external function and internal structure. The new ink can be easily printed from ordinary printers or written by lithographic pens.
The Apes: Challenges for the 21st Century conference addresses pressing issues affecting gorillas, orangutans, chimpanzees, bonobos, gibbons, and siamangs in both their natural habitats and zoos. The event brings together leading researchers to develop action plans on conservation, husbandry, and other key topics.
The Canadian Arthritis Network hosted a conference showcasing advancements in arthritis research and one-stop services for industry and government. The event featured key developments in therapeutics, diagnostics, and devices.
Research suggests that occupational lead exposure significantly increases the risk of developing Alzheimer's disease, particularly among those working in jobs with high levels of lead exposure. The study found a strong correlation between lead exposure and Alzheimer's, while other metals such as aluminum and solvents were not associate...
A team of scientists identified Io as the dominant source of the Jovian dust streams, which are high-rate bursts of submicron-sized particles. The particles' motion is strongly influenced by Jupiter's magnetic field, providing a unique signature that could only be present if Io were the dominant source.
A new NIH clinical advisory statement recommends using systolic blood pressure as the primary criterion for diagnosing and treating hypertension in middle-aged and older Americans. This shift aims to improve outcomes by targeting systolic pressure, which is associated with a higher risk of heart disease.
A new University of North Carolina at Chapel Hill study suggests that benzene is responsible for between 8% and 48% of all smoking-induced leukemia deaths. The chemical also causes between 12% and 58% of smoking-related deaths from acute myeloid leukemia.
A study found that medical students' biases against black female patients with chest pain can affect clinical decisions. White male students rated a black female patient as having less desirable health status but considered the white male patient's coronary condition more severe.
A study of 31 prostate cancer patients found that quality of life returns to normal within a year following brachytherapy, with urinary symptoms disappearing. The treatment was compared to other options like removal of the prostate or standard radiation therapy, which carry higher risks of decreased sexual function and bowel problems.
The University of California, San Diego has secured $47 million in private support to build a state-of-the-art cancer facility, with John and Rebecca Moores committing $20 million towards the project. The facility will bring together over 300 physicians, scientists, and staff to provide advanced patient care and conduct research.
A study of retired football players found that over half had experienced concussions, leading to increased risk of neurological complaints such as memory problems and numbness in extremities. The survey suggests that repeated blows to the head may cause lasting damage, prompting calls for regular testing to monitor player health.
Scientists have identified an unusual protein in anaerobic bacteria that senses oxygen and causes the bacteria to swim away from it. The protein could lead to the development of new antibiotics and provide insight into the evolution of life.
Scientists are using lasers to detect gravitational waves, which could help study dark matter and unlock the universe's secrets. The technique involves splitting a laser beam into two halves and comparing them for minute movements caused by space stretching.
The NHLBI has released a clinical advisory emphasizing the importance of systolic blood pressure in diagnosing and treating hypertension in middle-aged and older adults. The guideline recommends reducing systolic blood pressure to less than 140 mm Hg to reduce heart attack, heart failure, and stroke risk.
