The study's results show a 99.6% confidence level that no breast cancer is present if an MRI scan is normal, making preventive mastectomy unnecessary.
Researchers at University of Bonn aim to tap into the sediment archives of Lake Van, which store climate data from 800,000 years ago. The sediments contain detailed information on temperature and precipitation patterns, allowing scientists to reconstruct past climates.
Researchers discovered that male wasp spiders use a 'chastity belt' mechanism to block their female partner's sexual orifice during copulation, preventing offspring from other males. The detached genital tip plugs the orifice securely, impeding further copulation.
The brain's information processing is more chaotic than previously thought, with neurons releasing chemical messengers along their entire length. This challenges traditional understanding of neuronal communication and may lead to new medical drug development.
An international EU project led by the University of Bonn aims to shed light on why the immune system weakens with age, particularly in elderly people. The researchers will analyze up to 40,000 blood samples to develop new medicines that can largely inactivate viruses and enable the immune system to deal with residual viruses.
Scientists have discovered a gene called 'Titch' that plays a key role in the metabolism of insulin in flies and may also be relevant to humans. The finding has implications for the development of new drugs for Type II diabetes.
Researchers successfully tested a new method of treatment for fatal brain diseases like scrapie and Creutzfeld-Jakob, slowing disease progression by up to 97% in mice. The approach uses RNA interference to reduce production of the pathogenic prion protein.
Researchers from the University of Bonn have discovered how the eye adapts to darkness by forming a network that combines signals from multiple light-sensitive rods, boosting sensitivity. The study found that dopamine triggers the closure of a channel in amacrine II cells, inhibiting communication and allowing for signal focusing.
