Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»

Photoacoustic sensor achieves high-sensitivity detection of multiple greenhouse gases
Recently, Prof. Gao Xiaoming's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed a novel photoacoustic spectroscopy (PAS)-based sensor that enabled simultaneous, high-sensitive detection of CO2, CH4, and.....»»
Could you find what a lunar crater is made of by shooting it?
Americans are famously fond of their guns. So it should come as no surprise that a team of NASA scientists has devised a way to "shoot" a modified type of sensor into the soil of an otherworldly body and determine what it is made out of. That is prec.....»»
Apple Watch Series 10 review: Ultra inspired, mainstream desired, equilibrium acquired
For the last week, I’ve been testing the new Apple Watch — mostly by sleeping. That’s because Apple Watch Series 10 is capable of detecting signs of sleep apnea. I’ll need a few more weeks of sleep before possible sleep apnea can be flagge.....»»
Bridging large riverine ecosystems for inter-basin exchanges
Many of the world's large rivers have been modified to support food security, hydropower production, navigation and trade. While these developments are necessary to support a growing human population, they also pose substantial risks to the structure.....»»
Modified nano-sized cell particles found to boost cancer immunotherapy, reduce side effects
Immunotherapy is a type of cancer treatment that uses the body's own immune system to help fight cancer. This is by stimulating the immune response to recognize and attack cancer cells more effectively. The treatment involves using substances that bo.....»»
Three Apple Watches get FDA approval for sleep apnea detection, from today
Three Apple Watches have received approval for detecting sleep apnea, just in time for today’s launch of the feature in watchOS 11. The Federal Drug Administration approval was able to be granted swiftly on the basis that the way Apple is doing.....»»
Researchers develop novel covalent organic frameworks for precise cancer treatment delivery
