Physicists develop novel concept for detecting chiral molecules
In contrast to conventional mirrors, light can be reflected on surfaces known as metasurfaces without changing its polarization. This phenomenon has now been proven by physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the Ma.....»»
A human topological insulator: Researchers use choreographed dance to explain quantum materials
Science can be difficult to explain to the public. In fact, any subfield of science can be difficult to explain to another scientist who studies in a different area. Explaining a theoretical science concept to high school students requires a new way.....»»
Researchers develop high-quality nanomechanical resonators with built-in piezoelectricity
Researchers at Chalmers University of Technology in Sweden and at the University of Magdeburg in Germany have developed a novel type of nanomechanical resonator that combines two important features: high mechanical quality and piezoelectricity. This.....»»
Apple is researching smart glasses with an internal study, report claims
Apple is reportedly using an internal study to gauge interest in smart glasses as the company continues to develop its own Apple Glass, an eventual successor to Apple Vision Pro.Apple is reportedly exploring Smart Glasses with an internal study.The a.....»»
How many trees does it take to cool a city? Researchers develop tool to set urban tree canopy goals
Cities around the globe are increasingly experiencing dangerous heat as urban concrete and asphalt amplify rising temperatures. Tree-planting programs are a popular, nature-based way to cool cities, but these initiatives have been largely based on gu.....»»
COP29: AI can help develop climate-resistant crops for Africa—but it shouldn"t be left in the hands of corporates
How we use land and feed a growing global population, and the burden we place on natural habitats in pursuit of nutrition, will again take center stage at the annual global climate change conference, COP29, in November......»»
The Quantum Geometry That Exists Outside of Space and Time
A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the standard picture of how particles move......»»
Dora Richardson Took Her Research Underground to Develop Lifesaving Tamoxifen
When chemist Dora Richardson’s employer decided to terminate the breast cancer research on the drug Tamoxifen in the early 1970s, she and her colleagues continued the work in secret......»»

Using mathematics to better understand cause and effect
Cause and effect. We understand this concept from an early age. Tug on a pull toy's string, and the toy follows. Naturally, things get much more complicated as a system grows, as the number of variables increases, and as noise enters the picture. Eve.....»»
Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
Variations in scientific ethics: Chinese scientists prioritize government service more than global peers
In a new study of physicists from the U.S., U.K. and China, Rice University and Santa Clara University researchers found that Chinese scientists feel a greater obligation to serve their government with research efforts than international counterparts.....»»
Google on scaling differential privacy across nearly three billion devices
In this Help Net Security interview, Miguel Guevara, Product Manager, Privacy Safety and Security at Google, discusses the complexities involved in scaling differential privacy technology across large systems. He emphasizes the need to develop secure.....»»
International team discovers small molecules that regulate how fast plant leaves age
Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids. While the peptide SCOOP10 accelerates aging, SCOOP12 su.....»»
Single-molecule tracking technology streamlines drug discovery
New drug discovery is a critical step for improving patients' lives. First, researchers must identify molecules in the body's cells that help drive disease, as these are potential targets for new drugs. The next step is to screen candidate drugs that.....»»
