Scientists at the University of Michigan used spatial illusion to study how the brain processes sound. By analyzing neural activity in cats and humans, researchers found that the auditory systems use similar spectral characteristics to determine sound locations.
Caffeine in coffee can cross the fetal blood-brain barrier, triggering seizures in newborns. Oxygen starvation during delivery also plays a role, as it disrupts normal neuronal function.
A joint project between Nissan and MIT, the system uses computer and sensor data to monitor driving patterns and predict actions. With accuracy of 95%, it aims to build cars that adapt to individual drivers' needs.
Researchers at the University of Toronto found a strong association between magnetic field exposures in residences and the risk of developing childhood leukemia. Children exposed to higher levels of magnetic fields were two to four times more likely to develop leukemia, with risks highest for those diagnosed before age six.
Researchers confirmed that one type of genetic mutation causes inherited profound deafness, while another does not. Genetic tests found 42% of individuals with moderate to profound congenital deafness had sequence variations in the GJB2 gene.
Chinese and U.S. researchers have discovered a previously unknown species of primitive bird with the world's oldest surviving horny beak, dating back 130 million years. The discovery adds weight to the argument that birds descended from earlier reptile ancestors rather than dinosaurs.
The number of centenarians in the US is growing rapidly, with projections suggesting a doubling trend. The population is expected to become more diverse, with significant increases in Hispanic and Asian populations.
A team of geologists and aid workers warn that the Sarez Lake in Tajikistan is a ticking time bomb, with a natural dam on the verge of breaching. If the dam fails, it could unleash a wall of water devastating hundreds of mountain villages and killing hundreds of thousands of people.
A genetic trait has been found to predispose people to Gulf War syndrome, a condition where veterans of the war may have gotten ill from chemical exposures. The study reveals that people with high levels of a specific enzyme did not get sick, while those with low levels did.
The Columbia Glacier in Alaska has increased its speed to 35 meters per day, raising concerns among scientists about a rapid decline. The glacier, already the fastest moving glacier in the world, is now expected to retreat at an alarming rate, potentially posing risks to shipping lanes and marine ecosystems.
A new study uses computational tools to track human cancer development, suggesting that adenoma and carcinoma lines can arise from a common precursor but develop in parallel. This challenges the conventional model of cancer progression, which assumes a linear process from normal cell to polyp to cancer.
Chimpanzees demonstrate ability to visually recognize and match portraits of female relatives, potentially aiding kinship decisions and alliances. This skill may have played a role in the evolution of complex societies among primates.
A study by the Virginia Tech Center for Housing Research found that low-income families spend over half of their income on rent in Virginia. The rent burden index for these families increased from 42% to 51.2% between 1989 and 1996, with some localities having rent burdens exceeding 70%.
A newly developed blood test detects 97% of adrenal gland tumors, providing earlier and more accurate diagnoses. The test measures levels of hormones metanephrine and normetanephrine, which are consistently elevated in pheochromocytomas.
In a groundbreaking two-year study, nearly two-thirds of postmenopausal women with osteoporosis regained their original bone mass after receiving a new treatment. The synthetic parathyroid hormone treatment was three times more effective than current medications in reversing bone loss.
A team of scientists, led by Deborah J. Good, has identified a gene called SIL that governs the formation of the left-right body axis during embryonic development. The gene is believed to be crucial in the correct placement of organs such as the heart within the developing organism.
Scientists at the University of Rochester have discovered that shape plays a crucial role in copying DNA, contradicting previous theories that relied on hydrogen bonds. This finding has significant implications for cancer diagnosis and potential applications in artificial DNA creation.
A UCSF study found that raloxifene, an osteoporosis prevention drug, significantly reduced the risk of invasive breast cancer in postmenopausal women by 76 percent. The drug also showed promise in preventing both breast and osteoporosis simultaneously.
The Max-Planck-Gesellschaft has developed a new method for deriving reliable information from experimental data using probability theory, providing significant cost savings. The 'multi-resolution method' is widely applicable to various fields, including fusion research, medicine, and astronomy.
Researchers from the University of Notre Dame and NASA's Goddard Space Flight Center used an infrared spectrometer to determine the carbon monoxide/water ratio in comet Hale-Bopp. The findings suggest that the comet formed 4 billion years ago, providing clues about its history and composition.
