We can directly see the hidden world of atoms thanks to electron microscopes, first developed in the 1930s. Today, electron microscopes, which use beams of electrons to illuminate and magnify a sample, have become even more sophisticated, allowing scientists to take real-world snapshots of materials with a resolution of less than half the diameter [...]
We humans have evolved a rich repertoire of communication, from gesture to sophisticated languages. All of these forms of communication link otherwise separate individuals in such a way that they can share and express their singular experiences and work together collaboratively. In a new study, technology replaces language as a means of communicating by [...]
Ultrasensitive nanoscale optical probes have been created by scientists from UC Santa Cruz, to observe the bioelectric activity of neurons and other excitable cells. This innovative readout technology could allow researchers to analyze how neural circuits operate at a scale like never before, by observing large numbers of individual neurons at the same time. [...]
Advances made during recent clinical trials mean that those suffering from celiac disease may soon be able to reintroduce gluten back into their diet. This breakthrough is down to a progressive new treatment that makes innovative use of nanotechnology. Developed by a team of researchers at Northwestern University, the treatment deploys a biodegradable nanoparticle [...]
A new way of editing the code of life could correct 89% of the errors in DNA that cause disease, say US scientists. The technology, called prime editing, has been described as a "genetic word processor" able to accurately re-write the genetic code. It has been used to correct damaging mutations in the lab, [...]
A research team of Ehime University paved a way to achieve unexplored III-V semiconductor nanostructures. They grew branched GaAs nanowires with a nontoxic Bi element employing characteristic structural modifications correlated with metallic droplets, as well as crystalline defects and orientations. The finding provides a rational design concept for the creation of semiconductor nanostructures with [...]
While many people love colorful photos of landscapes, flowers or rainbows, some biomedical researchers treasure vivid images on a much smaller scale – as tiny as one-thousandth the width of a human hair. To study the micro world and help advance medical knowledge and treatments, these scientists use fluorescent nano-sized particles. Quantum dots are [...]
Energy is information. Lengthening the time during which a system is capable of retaining energy before losing it to the local environment is a key goal for the development of quantum information. This interval is called the "coherence time". Several studies have been performed with the aim of retarding decoherence. A study conducted by [...]
Just because a model catalyst effectively drives a reaction in a well-controlled environment doesn’t mean it will work as well under more practical conditions. For years, scientists have strived to predict catalysts’ performance. In an ultrahigh vacuum model reactor, catalysts typically work at lower pressures and temperatures than in applied catalytic reactor studies. Now, [...]
Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects. Researchers [...]
