Published Enhancing at-home COVID tests with glow-in-the dark materials


Researchers are using glow-in-the-dark materials to enhance and improve rapid COVID-19 home tests.
Published Pioneering study shows flood risks can still be considerably reduced if all global promises to cut carbon emissions are kept


Annual damage caused by flooding in the UK could increase by more than a fifth over the next century due to climate change unless all international pledges to reduce carbon emissions are met, according to new research.
Published Graphene quantum dots show promise as novel magnetic field sensors


Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.
Published Mineral particles and their role in oxygenating the Earth's atmosphere


Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.
Published Two-dimensional quantum freeze


Researchers have succeeded in simultaneously cooling the motion of a tiny glass sphere in two dimensions to the quantum ground-state. This represents a crucial step towards a 3D ground-state cooling of a massive object and opens up new opportunities for the design of ultra-sensitive sensors.
Published Mississippi River Delta study reveals which human actions contribute to land loss


Scientists reveal new information about the role humans have played in large-scale land loss in the Mississippi River Delta -- crucial information in determining solutions to the crisis.
Published Bending 2D nanomaterial could 'switch on' future technologies


Materials scientists have uncovered a property of ferroelectric 2D materials that could be exploited in future devices.
Published The positive outlooks of studying negatively-charged chiral molecules


The ability to distinguish two chiral enantiomers is an essential analytical capability for chemical industries including pharmaceutical companies, flavor/odor engineering and forensic science. A new wave of chiral optical methods have shown significant improvements in chiral sensitivity, compared to their predecessors, leading to potential analytical advantages for chiral discrimination.
Published Sea level rise poses particular risk for Asian megacities



Sea level rise this century may disproportionately affect certain Asian megacities, according to new research that looks at the effects of natural sea level fluctuations in addition to climate change. The study identified several Asian megacities that may face especially significant risks by 2100, including Chennai, Kolkata, Yangon, Bangkok, Ho Chi Minh City, and Manila.
Published Ocean surface tipping point could accelerate climate change



A study has found that intense global warming could shut down the ocean's ability to soak up carbon dioxide, leading to accelerated global warming as the greenhouse gas accumulates in the atmosphere. The decline happens because of a surface layer of low-alkalinity water that emerges during extreme warming that hinders the ability of the oceans to absorb CO2. The study is based on a climate simulation configured to a worst-case emissions scenario that the researchers say must be avoided at all costs.
Published Catalyst purifies herbicide-tainted water and produces hydrogen


Researchers have developed a dual-purpose catalyst that purifies herbicide-tainted water while also producing hydrogen.
Published Scholars unify color systems using prime numbers


Existing color systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colors, making them difficult to compute and time-consuming to convert. Recently, researchers made a breakthrough by inventing an innovative color system, called 'C235', based on prime numbers, enabling efficient encoding and effective color compression. It can unify existing color systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colorizing DNA codons.
Published Researchers propose a simple, inexpensive approach to fabricating carbon nanotube wiring on plastic films


Researchers have developed an inexpensive method for fabricating multi-walled carbon nanotubes (MWNTs) on a plastic film. The proposed method is simple, can be applied under ambient conditions, reuses MWNTs, and produces flexible wires of tunable resistances without requiring additional steps. It eliminates several drawbacks of current fabrication methods, making it useful for large-scale manufacturing of carbon wiring for flexible all-carbon devices.
Published A motion freezer for many particles


From the way that particles scatter light, it is possible to calculate a special light field that can slow these particles down. This is a new and powerful method to cool particles down to extremely low temperatures.
Published Tiny new climbing robot was inspired by geckos and inchworms


A tiny robot that could one day help doctors perform surgery was inspired by the incredible gripping ability of geckos and the efficient locomotion of inchworms.
Published Faster and sharper whole-body imaging of small animals with deep learning


A research team presents technology that enhances photoacoustic computed tomography using a deep-learning approach.
Published Fastest laser camera films combustion in real time


A research team has developed one of the world's fastest single-shot laser cameras, which is at least a thousand times faster than today's most modern equipment for combustion diagnostics. The discovery has enormous significance for studying the lightning-fast combustion of hydrocarbons.
Published Making engineered cells dance to ultrasound


A team has developed a method for selectively manipulating genetically engineered cells with ultrasound.
Published Let there be (controlled) light


In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively control photonic quantum states -- the so-called qubits -- are needed. Physicists have made a breakthrough in this effort: for the first time, they demonstrated the controlled creation of single-photon emitters in silicon at the nanoscale.
Published Artificial intelligence conjures proteins that speed up chemical reactions


Scientists have used machine learning to create brand-new enzymes, which are proteins that accelerate chemical reactions. This is an important step in the field of protein design as new enzymes could have many uses across medicine and industrial manufacturing. The research team devised deep-learning, artificial intelligence algorithms that created light-emitting enzymes called luciferases. Laboratory testing confirmed that the new enzymes can recognize specific chemicals and emit light very efficiently.
