A study by researchers at the National Institute of Child Health and Human Development found that consuming high amounts of caffeine doubles the risk of miscarriage. Moderate caffeine consumption was not linked to an increased risk, however.
Researchers have discovered a mechanism by which the galaxy is seeded with gas to form new stars, solving a long-standing question of galactic evolution. The discovery confirms that high-velocity clouds play a key role in the chemical evolution of the galaxy by showering it with metal-poor gas.
Oregon Health Sciences University researchers have found a genetic link between vascular disease and the human cytomegalovirus (CMV), a member of the herpes family. The study suggests that CMV stimulates smooth muscle cell migration, leading to inflammation and blockage in artery walls.
A study by MGH researchers has identified a gene malfunction that appears central to the development of type 1 diabetes. The malfunction affects the Lmp2 protein, which is required for immune system cells to recognize self-proteins, leading to an autoimmune reaction.
Seattle researchers have described the structure of factor VIII, a key blood-clotting protein implicated in hemophilia A. The discovery provides a key to developing improved blood-thinning medications and clotting agents for hemophiliacs, as well as better treatments for those at risk of stroke and heart attack.
Threadsnakes have evolved a unique feeding mechanism, devouring pupae and larvae of ants at an incredible rate of three or four bites per second. This rapid-fire eating pattern may be crucial for their survival in ant-infested environments, allowing them to outsmart powerful worker ants and secure food.
A new transgenic mouse model develops damaging tau protein tangles as it ages, exhibiting clinical symptoms similar to tauopathies. The tau mouse is expected to aid in understanding the role of tau tangles in Alzheimer's disease and other neurodegenerative diseases.
A study by Kelly M. Everard found that social reasons for participating in activities, rather than the activity itself or frequency, have a direct bearing on well-being in older adults. Activities that bring a sense of connection and enjoyment tend to enhance well-being.
Global sulfur emissions have stabilized over the past 20 years, with China leading the world in emissions due to its massive coal reserves and growing industrialization. Cleaner fuels and pollution controls have contributed to the stabilization of emissions worldwide.
