After a decade-long search, an international team of researchers including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have for the first time detected a gamma-ray burst in very-high-energy gamma light. This discovery was made in July 2018 by the H.E.S.S. collaboration using the huge 28-m telescope of the H.E.S.S. array in Namibia. Surprisingly, this Gamma-ray burst, an extremely energetic flash following a cosmological cataclysm, was found to emit very-high-energy gamma-rays long after the initial explosion.
Gamma-ray bursts are the most energetic phenomenon known to humankind. Although short-lived, they outshine stars and even galactic quasars. They usually display energies in the region of tens of giga-electron-volts, but for the first time, researchers discovered a gamma-ray burst in the region of a tera-electron-volt. This level of energy has long been theorized, and this study demonstrates these energies might actually be more common than once thought.
Professor Nikolaus Rajewsky is a visionary: He wants to understand exactly what happens in human cells during disease progression, with the goal of being able to recognize and treat the very first cellular changes. "This requires us not only to decipher the activity of the genome in individual cells, but also to track it spatially within an organ," explains the scientific director of the Berlin Institute for Medical Systems Biology (BIMSB) at the Max Delbrück Center for Molecular Medicine (MDC) in Berlin.
The effectiveness of non-mechanical, low-energy methods for moderating temperature and humidity has been evaluated in a series of experiments by researchers from the University of Cambridge.
DURHAM, N.C. -- Engineers at Duke University have developed a microscope that adapts its lighting angles, colors and patterns while teaching itself the optimal settings needed to complete a given diagnostic task.
In the initial proof-of-concept study, the microscope simultaneously developed a lighting pattern and classification system that allowed it to quickly identify red blood cells infected by the malaria parasite more accurately than trained physicians and other machine learning approaches.
New Rochelle, NY, November 20, 2019 -- Diagnostic agreement between practitioners is an ongoing challenge in the evaluation of Traditional Chinese Medicine (TCM) and other healthcare systems that rely on constitutional types.
About 10% of the world population suffers from migraine headaches, according to the National Institute of Neurological Disorders and Stroke. To alleviate migraine pain, people are commonly treated with opioids. But, while opioid treatment can provide temporary pain relief for episodic migraines, prolonged use can increase the frequency and severity of painful migraines.
Researchers have tried to understand how opioids cause this paradoxical increase in pain for a decade, but the mechanism remained elusive -- until now.
Researchers from the University of Houston have reported a new device that can both efficiently capture solar energy and store it until it is needed, offering promise for applications ranging from power generation to distillation and desalination.
Sensing a hug from your friend through a video call with him/her may become a reality soon. A joint-research team consisted of scientists and engineers from City University of Hong Kong (CityU) and Northwestern University in the United States has developed a skin-integrated virtual reality (VR) system, which can be controlled and powered wirelessly. The innovation has great application potential in communications, prosthetic control and rehabilitation, as well as gaming and entertainment.
UPTON, NY--Scientists have developed a new approach for making metal-metal composites and porous metals with a 3-D interconnected "bicontinuous" structure in thin films at size scales ranging from tens of nanometers to microns. Metallic materials with this sponge-like morphology--characterized by two coexisting phases that form interpenetrating networks continuing over space--could be useful in catalysis, energy generation and storage, and biomedical sensing.
