Researchers develop technique to visualize individual vesicles after release, discovering three modes of recycling: kiss-and-run, compensatory and stranded. The study reveals the rate of synaptic vesicle recycling determines information transmission in nerve cells.
Health care providers must recognize unusual disease trends and early warning signs of intentional water contamination. With prompt diagnosis and proper management, they can make a difference in minimizing the impact of such an event.
The Northwestern Memorial Hospital is leading an international brain aneurysm study to confirm a familial link and identify specific genes responsible for the development of intracranial aneurysms. The goal is to prevent and treat aneurysms early, reducing premature mortality and morbidity associated with this type of stroke.
A study found that people with a gun in their home are almost twice as likely to die in a gun-related homicide and 16 times more likely to use a gun to commit suicide than those without. Handguns account for most domestic homicides and suicides, highlighting the dangers of gun ownership.
Researchers used ancient pollen data to test hypotheses on species diversity and coexistence in forests. They found that stabilizing forces, not neutral dynamics, were maintaining forest diversity, contradicting long-held views.
New guidelines published in Agronomy Journal provide a standardized approach to soil surveying and mapping, allowing farmers to make data-driven decisions. The technology is expected to revolutionize the agricultural industry within the next one to two decades.
Researchers at the Salk Institute have developed a detailed model of how stem cells produce motor neurons, which could lead to new treatments for spinal cord injuries and diseases affecting motor nerve cells. The study demonstrates an unusually efficient yield of 60 percent motor nerves using two key gene and protein-regulated pathways.
Researchers found that twins who started menstruating earlier were more likely to develop breast cancer, suggesting a link between puberty hormones and genetic susceptibility. The study provides new insights into the causes of hereditary breast cancer and potential targets for intervention.
Using a modified version of a naturally occurring human protein, researchers were able to significantly reduce the spread of disease and decrease tumor growth without evidence of toxicity. The modified protein was able to interfere with cancer cells' ability to stick to one another and other healthy cells.
Federal regulations and hospital policies can leave patients in debt due to lack of clear guidelines on free or discounted care. Hospitals often do not have procedures for negotiating discounts with uninsured patients who cannot afford full charges.
