Large molecules need more help to travel through a nuclear pore into the cell nucleus
Model systems based on virus capsids have shown how large biomolecules are able to penetrate a cell nucleus. The larger the molecule, the more nuclear localization signals are needed.
Beijing International Film Festival opens to sold-out crowd, state media says
The annual Beijing International Film Festival opened over the weekend as industry executives said 8,500 movie theaters have resumed operations amid the coronavirus pandemic.
New device turns sunlight, CO2, water into carbon-neutral fuel
Engineers at the University of Cambridge have developed a device that converts sunlight, carbon dioxide and water into a carbon-neutral fuel, without the need for electrical components.
A novel approach produces a completely new kind of dynamic light structure
It is not every day that scientists are able to produce an entirely new kind of light, but when they do the implications can be dramatic. When twisted light beams...
Routing valley exciton emission of a monolayer via in-plane inversion-symmetry broken PhC slabs
The valleys of two-dimensional transition metal dichalcogenides (TMDCs) offer a new degree of freedom for information processing and have attracted tremendous interest for their possible applications in valleytronics. To develop...
Machine learning peeks into nano-aquariums
In the nanoworld, tiny particles such as proteins appear to dance as they transform and assemble to perform various tasks while suspended in a liquid. Recently developed methods have made...
Study enables predicting computational power of early quantum computers
Quantum physicists at the University of Sussex have created an algorithm that speeds up the rate of calculations in the early quantum computers which are currently being developed. They have...
A leap forward for biomaterials design using AI
Researchers at Tokyo Institute of Technology (Tokyo Tech) have used artificial intelligence (AI) to predict the degree of water repulsion and protein adsorption by ultra-thin organic materials. By enabling accurate...

Ocean hitchhiker's sucker mechanism offers potential for underwater adhesion
A new study has revealed how remora suckerfish detach themselves from the surfaces they've clung to—and how the mechanism could provide inspiration for future reversible underwater adhesion devices.
A light touch for membrane selectivity
Membranes that change their pore size in response to external stimuli, such as pH, heat and light, are set to transform separation science and technology. Such smart membranes developed by...
Researchers Generate Attosecond Light from Industrial Laser
University of Central Florida researchers are making the cutting-edge field of attosecond science more accessible to researchers from all disciplines. Their method to help open up the field is detailed...
Binding carbon dioxide using broken concrete
Thanks to technology from ETH spin-off Neustark, concrete recycling plants can store carbon dioxide over the long term.
Syringe technology could enable injection of concentrated biologic drugs
MIT researchers have developed a simple, low-cost technology to administer powerful drug formulations that are too viscous to be injected using conventional medical syringes. The technology, which is described in...
New ultra-long circulating nanoparticle developed for chronic myeloid leukemia
An ultra-long circulating nanomaterial has been developed by researchers through the conjugation of CHMFL-ABL-053 to an amphiphilic polymer and subsequent self-assembly into a nanoparticle (NP) with high loading.
High-resolution and large field-of-view Fourier ptychographic microscopy
Fourier ptychographic microscopy (FPM) is a computational imaging and quantitative phase imaging (QPI) technique. It effectively tackles the trade-off between resolution and field-of-view (FOV) in conventional microscopy. It can obtain...
Electrons boost solid-state caloric cooling in hexagonal sulfides
A research team has found a new type of giant barocaloric (BC) material (hexagonal sulfides) and discovered an important role of electrons in boosting the total entropy change driven by...
Nanoscale imaging of dopant nanostructures in silicon-based devices
When fabricating integrated circuits and different types of silicon-based devices, researchers need to position dopant nanostructures in specific ways with high levels of precision. However, arranging these structures at the...
Deep space mine
Many resources essential to the technology on which we depend are dwindling or are increasingly inaccessible to certain nations for geopolitical reasons. A case in point is that several of...
A measurement of positronium’s energy levels confounds scientists
Positronium is positively puzzling. A new measurement of the exotic “atom” — consisting of an electron and its antiparticle, a positron — disagrees with theoretical calculations, scientists report in the Aug. 14 Physical...
Baltimore Ravens cut All-Pro S Earl Thomas after altercation in practice
The Baltimore Ravens released All-Pro safety Earl Thomas less than two days after his involvement in an on-field altercation with teammate Chuck Clark.
The factory of the future, batteries not included
Many analysts have predicted an explosion in the number of industrial “internet of things” (IoT) devices that will come online over the next decade. Sensors play a big role in...
Surface deep: Light-responsive top layer of plastic film induces movement
Scientists show that only a thin, topmost layer of the light-dependent azobenzene-containing plastic film needs to be light-sensitive, rather than the entire film, opening up new ways to potentially reduce...
Energy-storing walls made from ordinary red bricks
Researchers turn bricks into supercapacitors by depositing conductive materials in their pores
Podcast: Chemists debate the value of name reactions in organic chemistry
Name reactions are commonly heard in organic chemistry–speak, and they're mainly named after white men. Stereo Chemistry asks whether this is a problem, whether we should stop using them, and...
