First high-resolution 3D nanoscale chemical imaging achieved with multi-modal tomography
By exploiting a smart learning algorithm that fuses two microscopy signals, University of Michigan researchers have accomplished high-resolution, efficient 3D chemical imaging for the first time at the one-nanometer scale. For context, a nanometer is.....»»
Inexpensive spring truffles or exquisite Piedmont truffles? New analytical method can detect food fraud
Some truffles are particularly expensive and therefore often the target of food fraud. For example, high-priced Piedmont truffles (Tuber magnatum) are often difficult to distinguish from the cheaper spring truffles (T. borchii) on the basis of their.....»»
NASA lays out how SpaceX will refuel Starships in low-Earth orbit

Porsche dealership sales manager took bribes in exchange for high-demand vehicles, lawsuit alleges
The sales manager of a Porsche dealership in South Carolina commanded hundreds of thousands of dollars in "under-the-table" payments from customers hungry for high-demand vehicles......»»
Theoretical biologists test two modes of social reasoning and find surprising truths in simplicity
Imagine a small village where every action someone takes, good or bad, is quietly followed by ever-attentive, nosy neighbors. An individual's reputation is built through these actions and observations, which determines how others will treat them. The.....»»
Pump-probe high-harmonic spectroscopy could catch geometric phase effect around conical intersection in molecule: Study
A collaborative research team from Nanjing University of Science and Technology (NJUST) and East China Normal University (ECNU) has theoretically proposed that a pump-probe high-harmonic spectroscopy (HHS) driven by VUV-IR pulses can catch the geomet.....»»
What long-standing Apple bug most bugs you? This is mine …
While shiny new features are lovely, what I find most frustrating with Apple OS updates is when a long-standing bug doesn’t get fixed … update after update after update. For me, there is one that Mac bug which really stands out, that has been.....»»
Researchers unveil novel attack methods targeting Intel’s conditional branch predictor
Researchers have found two novel types of attacks that target the conditional branch predictor found in high-end Intel processors, which could be exploited to compromise billions of processors currently in use. The multi-university and industry resea.....»»

Researchers achieve electrosynthesis via superwetting organic-solid-water interfaces
Chinese scientists have recently achieved the direct synthesis of high-purity benzaldehyde chemicals from the selective electrooxidation of benzyl alcohol. The organic-solid-water (OSW) three-phase reaction system has shown particular advantages in r.....»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Topologically controlled multiskyrmions: Researchers propose a new family of quasiparticles
Skyrmions are topologically protected quasiparticles with sophisticated spin textures, widely studied in condensed-matter systems, magnets and recently in photonics, which predicts great potential in ultra-high-capacity information storage, due to th.....»»
Webb captures iconic Horsehead Nebula in unprecedented detail
The NASA/ESA/CSA James Webb Space Telescope has captured the sharpest infrared images to date of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show a part of the iconic nebula in a whole new light, capturi.....»»
