James Webb telescope detects traces of neutron star in iconic supernova
Feb 22, 2024 (Nanowerk News) Supernovae are the spectacular end result of the collapse of stars more massive than 8-10 times the mass of the sun. Besides being the main sources of chemical elements such as carbon, oxygen, silicon, and iron that make life possible, they are also responsible for...
A new chapter for all-attosecond spectroscopy
Feb 22, 2024 (Nanowerk News) A team of researchers from the Max Born Institute in Berlin has for the first time demonstrated attosecond-pump attosecond-probe spectroscopy (APAPS) at a repetition rate of 1 kilohertz. This became possible by the development of a compact intense attosecond source using an out-of-focus generation geometry....
Steering light with supercritical coupling
Feb 22, 2024 (Nanowerk News) Researchers from the National University of Singapore (NUS) have unveiled a novel concept termed “supercritical coupling” that enables several folds increase in photon upconversion efficiency. This discovery not only challenges existing paradigms, but also opens a new direction in the control of light emission. Photon...
Silicon microresonators for artificial neural networks

A nanosensor for brain chemistry analysis
Feb 22, 2024 (Nanowerk News) Longstanding challenges in biomedical research such as monitoring brain chemistry and tracking the spread of drugs through the body require much smaller and more precise sensors. A new nanoscale sensor greatly outperforms standard technologies by monitoring areas 1,000 times smaller and tracking subtle changes in...
numerous products, no acute dangers
Feb 22, 2024 (Nanowerk News)Think big. Despite its research topic, this could well be the motto of the Graphene Flagship, which was launched in 2013: With an overall budget of one billion Euros, it was Europe's largest research initiative to date, alongside the Human Brain Flagship, which was launched at...
Breakthrough optical platform unlocks secrets of natural swarm intelligence for next-gen collective microrobotics (w/videos)
Feb 21, 2024 (Nanowerk Spotlight) The remarkable collective motions exhibited by natural groups like schools of fish or flocks of birds have captivated scientists for generations. Teasing apart the factors enabling such coordinated swarming behaviors remains deeply challenging though, despite extensive observation and modeling efforts. Beyond satisfying curiosity, a deeper...
Spinning, magnetic micro-robots help researchers probe immune cell recognition
Feb 21, 2024 (Nanowerk News) Researchers at the Pritzker School of Molecular Engineering and the Department of Chemistry at the University of Chicago have engineered tiny, spinning micro-robots that bind to immune cells to probe their function. The robot, or “hexapod,” gives scientists a new, highly adaptable way to study...
Electrons become fractions of themselves in graphene
Feb 21, 2024 (Nanowerk News) The electron is the basic unit of electricity, as it carries a single negative charge. This is what we’re taught in high school physics, and it is overwhelmingly the case in most materials in nature. But in very special states of matter, electrons can splinter...
