Emory University researchers found that newborn rat pups who received more infantile stimulation handled stress better in adulthood, both externally and internally. The study suggests that early experiences shape the development of the hypothalamic-pituitary-adrenal response to stress, which can have implications for human health.
Researchers have identified a key to targeting retroviruses to specific cells, paving the way for precise gene therapy delivery. The high-resolution structure of the virus's envelope protein reveals a precise pattern of ridges and valleys that determines cell accessibility.
Research suggests that aging has a modest impact on sensory perception, particularly smell, taste, and touch. Most older adults can detect scents and flavors similar to those of younger individuals.
Researchers have discovered a new state of matter in clusters of sodium atoms, exhibiting lower melting points than expected. The phenomenon challenges conventional physics and raises questions about the behavior of solid and liquid states in small particles.
Scientists confirm British Columbia was once nearly 2,000 miles south of its current location based on fossil evidence and magnetism. The discovery supports the theory of massive Earth movements along a gigantic faultline.
Researchers found stents lower risk of death, heart attack, and repeat surgery compared to angioplasty for patients with obstructed vein grafts. The study's results suggest a new standard of care for hundreds of thousands of post-bypass patients.
A recent study led by Professor Susan Fisher of the University of California at San Francisco found that low oxygen levels regulate cell proliferation in early pregnancy, controlling placental development. The team also discovered a process similar to cancerous growth occurs when cells invade healthy tissue under low-oxygen conditions.
