A new non-invasive technique for parchment diagnosis
The conservation state of parchments is typically assessed using invasive and sometimes destructive investigation techniques. Scientists from Université Paris-Saclay, the CNRS, École Polytechnique, and the French Ministry of Culture have developed.....»»
Single sideband modulation technique can relax the bandwidth restriction
As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many applications, such as electronic warfare, wireless communications and modern radar systems. Initially, ASK microwave signals are generated based on radio frequenc.....»»
Invasive alien species are a serious threat to the planet: Four key messages for Africa
Climate change has negatively—and irreversibly, in some cases—affected ecosystems around the globe. Sadly, though, it is not the only phenomenon that's altering our natural world......»»
Why invasive ants are a silent threat to our ecosystems
Invertebrates are often described by experts as the "little things that run the world," and ants are certainly one of the top contenders for this role. Ants help ecosystems to function normally and the total weight of all ants on Earth is roughly equ.....»»
Brazilian researchers develop method of purifying water contaminated by glyphosate
Researchers at São Paulo State University (UNESP) in Brazil have developed a strategy for removing glyphosate, one of the world's most frequently used herbicides, from water. Inspired by the concept of the circular economy, the technique is based on.....»»
Investigating invasive plants as roadside contaminant removal tools
Tall, densely growing Phragmites and cattail (Typha) are familiar plants alongside highways and byways in the northern United States, flourishing in salty roadsides and degraded wetland environments created by chemicals applied to roads in the colder.....»»
Bridging the gap: New terrain smoothing method refines downslope windstorm modeling
Researchers from the UK Met Office, in collaboration with the Chinese Academy of Meteorological Sciences, have developed an advanced terrain-smoothing technique that significantly improves the modeling of downslope windstorms. This innovative approac.....»»
New imaging technique detects virus movement in unprecedented detail
Proteins are the workhorses of biological systems, carrying out their work with extraordinary precision and speed. For years, observing proteins in action has been a significant challenge, as imaging methods often lacked sufficient speed and resoluti.....»»
Technique for 3D printing metals at the nanoscale reveals surprise benefit

The secret world of rhododendrons: A plant more ancient than the Himalayas
If you have a rhododendron in your garden or pass one by on an afternoon walk perhaps you think of it as just a colorful and pretty shrub. You may have heard that they come from the Himalayas, and that they are invasive plants that destroy ecosystems.....»»
Unveiling the invisible: A bioinspired CMOS-integrated polarization imaging sensor
Polarimetric imaging can uncover features invisible to human eyes and conventional imaging sensors, and it is becoming an ever more essential technique in modern society. Conventional polarimetric imaging systems require complex optical components an.....»»
Synergy of traditional techniques and deep learning enables single-frame high-precision fringe pattern analysis
Optical metrology, as a general-purpose metrology technique that uses light as information carriers for non-contact and non-destructive measurement, is fundamental to manufacturing, basic research, and engineering applications......»»
A NICER approach to genome editing
The gene editing technique CRISPR/Cas9 has allowed researchers to make precise and impactful changes to an organism's DNA to fix mutations that cause genetic disease. However, the CRISPR/Cas9 method can also result in unintended DNA mutations that ma.....»»
Team develops technique for building DNA-based programmable gate arrays
A team of chemists and chemical engineers at Shanghai Jiao Tong University, working with a colleague from the Chinese Academy of Sciences, both in China, has built a DNA-based programmable gate array for use in general-purpose DNA computing. In their.....»»
Enhancing atherosclerosis diagnosis using ultrasmall calcium carbonate nanoparticles
Atherosclerosis is characterized by the hardening of blood vessels, especially certain arteries, due to the local buildup of fibers and lipids (mainly cholesterol) in the inner wall of an artery, causing it to narrow. It is a complex disease that can.....»»
Optimizing cacao pollination for higher yields
A research team including Ingolf Steffan-Dewenter's Department of Animal Ecology and Tropical Biology has investigated how the cultivation of cacao can be improved by using the right pollination technique. The success of cacao cultivation depends to.....»»
