Physicists have discovered that entangled photons, a phenomenon in quantum physics, can create smaller features on lithographic masks than classical physics allows. This breakthrough could enable manufacturers to continue miniaturizing and speeding up computer chips, potentially breaking the Moore's law barrier.
The NEAR mission has provided definitive mass and density measurements of asteroid 433 Eros, confirming it is an undifferentiated, homogeneous structure. The asteroid's surface features spectacular images and movies showing ridges, pits, troughs, and grooves that provide fascinating clues about its history.
Researchers at Ohio State University have created a compact disc that can analyze blood samples and store medical information, using tiny reservoirs and channels to mix fluids. The technology enables the CD to measure glucose levels, store data, and even calibrate sensors.
A new study found that continued exercise significantly reduces the chances of depression returning, with only 8% of patients in the exercise group relapsing compared to 38% and 31% of the drug-only and exercise-plus-drug groups. Researchers suggest that exercise may be beneficial due to its active role in improving mental health.
Researchers found that urban living increases the risk of asthma among black children in the US, while highly active antiretroviral therapy reduces TB and Mycobacterium avium complex infections in HIV patients. Prenatal corticosteroid treatment also boosts surfactant production in preterm infants with respiratory distress syndrome.
Researchers aim to design technology that allows users to create profiles of their information interests, enabling customized information services and efficient data recharging on portable devices. The team plans to develop a profiling language and middleware techniques to track users' online needs.
The extinction of the Miss Waldron's red colobus monkey is a warning sign of an impending ecological disaster in West Africa. The loss of large-bodied monkeys, including primates and forest antelope, threatens the region's biodiversity, highlighting the need for improved law enforcement, protected areas, and conservation education.
The Congressional briefing explores how neighborhoods affect health risks, school achievement in children, and discrimination's impact on quality of life. Three experts share research findings about the importance of understanding and addressing neighborhood conditions.
Researchers at Ohio State University have developed tiny artificial muscles that can dispense medication through microscopic holes in a prototype 'smart pill' implant. The capsules measure only a few micrometers across and can be used to power micro-sized medical devices or separate chemicals.
A Brown University research team is creating innovative visualization tools to help scientists better analyze and understand complex data. The project combines techniques from painting, sculpture, and graphic design with perceptual psychology to provide more effective pictures of huge amounts of data.
A McGill University research project demonstrates streaming high-quality multichannel audio over the internet from Montreal to Los Angeles. The demonstration features renowned recording engineers mixing 12 channels of audio in real-time.
Researchers are developing BioMEMs, implant materials and devices that integrate micro- and nanoscale features to affect cellular function. These therapeutic systems use chip technology, material science, and bioengineering to grow heart cells in culture and protect implanted cells with precision.
Researchers create micropatterns of polyethylene glycol to glue biological entities to computer chips, enabling rapid detection of substances. The technique has potential applications in laboratory screening, implantable medical devices, and diagnostic devices.
Astronomer Joseph Veverka's team observed a 'saturated' surface with tiny craters and abundant blocks of ejected debris on asteroid 433 Eros. The low gravity is puzzling, as most ejecta would be expected to escape into space.
Researchers found that female mice lacking IRS-2 protein are infertile due to defective ovaries and abnormal hormone production. The study suggests an evolutionarily conserved pathway linking energy metabolism and fertility in humans and animals, with potential implications for diabetes treatment.
University of Maryland researchers successfully created a new brain circuit that takes over damaged vision functions in newborn hamsters. The study suggests that surgically created neural pathways might one day be used to treat brain damage and restore lost functions like vision or hearing.
Researchers found that bees can deliver a biological fungicide to strawberry blooms more effectively than mechanical sprayers, reducing infected strawberries by 72 percent. The bee-delivered natural fungicide was as effective as chemical sprays at preventing gray mold, a common disease in strawberries.
Researchers found that a Tat-specific killer T cell response can effectively contain simian immunodeficiency virus during early infection, leading to a massive immune response. The study suggests a new approach to designing HIV vaccines by stimulating immune responses against virus proteins produced within hours of infection.
The Fred Hutchinson Cancer Research Center is developing a new strategy for obtaining plants with desirable genetic mutations using the TILLING method. This approach allows for rapid and large-scale analysis of mutations without introducing genetically modified material.
