Researchers have developed a procedure to mimic in laboratory experiments a form of brain trauma commonly seen in combat veterans, and findings suggest a new diagnostic tool for early detection and a potential treatment.
Consider the pendulum of a grandfather clock. If you forget to wind it, you will eventually find the pendulum at rest, unmoving. However, this simple observation is only valid at the level of classical physics. However, quantum mechanics, the underlying physical rules that govern the fundamental behavior of matter and light at the atomic scale, state that nothing can quite be completely at rest.
An experimental drug trial is underway at the Fort Jackson military base in South Carolina.
In today’s world, it’s an exciting time for medical technology. And making smart use of modern digital innovations is bringing revolutions in health care for the young and old. The ability to combine information and function from various devices to personalize treatment based on individual conditions presents enormous opportunity to both improve health and reduce costs.
For the western honey bee, the swarming process begins when between 10 and 20 daughter queens develop in a colony, according to the Univ. of Florida. As the daughter queens develop from the larvae stage, the original mother queen and a portion of the hive branch out, and establish a new colony. What follows is a fight for dominance over the original hive. If the daughter queens emerge simultaneously, they fight until one remains.
Engineers at the Univ. of Toronto just made assembling functional heart tissue as easy as fastening your shoes. The team has created a biocompatible scaffold that allows sheets of beating heart cells to snap together just like Velcro.
Researchers from North Carolina State Univ. and the Univ. of North Carolina at Chapel Hill have for the first time created and used a nanoscale vehicle made of DNA to deliver a CRISPR-Cas9 gene-editing tool into cells in both cell culture and an animal model.
In 1906 at the 37th Conference of South-West German Psychiatrists in Tübingen, German physician Dr. Alois Alzheimer elucidated symptoms of a disease that would later be named after him. He described the case of 51-year-old woman Auguste D., and her progressive symptoms of cognitive impairment, hallucinations and delusions.
After initially injected into a well, a portion of hydraulic fracturing fluid returns to the surface immediately, dubbed “flow-back,” and some seeps up over the well’s lifespan, called “produced water.” A combination of water, chemical additives and naturally occurring substances, the fluid is typically stored at a fracking site before treatment, recycling or disposal.
The fungus Cryptococcus causes meningitis, a brain disease that kills about 1 million people each year—mainly those with impaired immune systems due to AIDS, cancer treatment or an organ transplant. It's difficult to treat because fungi are genetically quite similar to humans, so compounds that affect fungi tend to have toxic side effects for patients.
Generating and storing renewable energy, such as solar or wind power, is a key barrier to a clean-energy economy. When the Joint Center for Artificial Photosynthesis was established in 2010, the U.S. Dept. of Energy Energy Innovation Hub had one main goal: a cost-effective method of producing fuels using only sunlight, water and carbon dioxide, mimicking the natural process of photosynthesis in plants.
The ChilliBlock from Asynt is a new modular system purpose designed for precise, controlled cooling and heating of biological samples in microplates, vials and Eppendorf tubes. Traditionally, methods of cooling biological samples often rely upon direct immersion in ice buckets which are prone to considerable temperature variability, contamination and loss of wetted labels.
Optogenetics provides a powerful tool for studying the brain by allowing researchers to activate neurons using simple light-based signals. But until now, these optical stimulation techniques have been “open loop,” meaning they lack the kind of feedback control that most biological and engineering systems use to maintain a steady operating state.
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates and organic particles.
Considered some of the brightest objects in the universe, quasars are contained within active galaxies and powered by black holes billion times the mass of the sun.
