Say goodbye to the dots and dashes to enhance optical storage media

Purdue University innovators have created technology aimed at replacing Morse code with colored "digital characters" to modernize optical storage. They are confident the advancement will help with the explosion of remote data storage during and after the COVID-19 pandemic.

First images of muon beams

A new technique has taken the first images of muon particle beams. Nagoya University scientists designed the imaging technique with colleagues in Osaka University and KEK, Japan and describe it in the journal Scientific Reports. They plan to use it to assess the quality of these beams, which are being used more and more in advanced imaging applications.

Biosensors require robust antifouling protection

A new study found that electrons can reach ultra-relativistic energies for very special conditions in the magnetosphere when space is devoid of plasma.

Temperature, humidity, wind predict second wave of pandemic

The 'second wave' of the coronavirus pandemic has resulted in much blame placed on a lack of appropriate safety measures. However, due to the impacts of weather, research suggests two outbreaks per year during a pandemic are inevitable.

Venus flytraps found to produce magnetic fields

The Venus flytrap (Dionaea muscipula) is a carnivorous plant that encloses its prey using modified leaves as a trap. During this process, electrical signals known as action potentials trigger the closure of the leaf lobes. An interdisciplinary team of scientists has now shown that these electrical signals generate measurable magnetic fields. Using atomic magnetometers, it proved possible to record this biomagnetism. "You could say the investigation is a little like performing an MRI scan in humans," said physicist Anne Fabricant. "The problem is that the magnetic signals in plants are very weak, which explains why it was extremely difficult to measure them with the help of older technologies."

A new hands-off probe uses light to explore electron behavior in a topological insulator

Topological insulators are one of the most puzzling quantum materials—a class of materials whose electrons cooperate in surprising ways to produce unexpected properties. The edges of a TI are electron superhighways where electrons flow with no loss, ignoring any impurities or other obstacles in their path, while the bulk of the material blocks electron flow.

Researchers design next-generation photodetector

Northwestern University researchers have developed a new approach to quantum device design that has produced the first gain-based long-wavelength infrared (LWIR) photodetector using band structure engineering based on a type-II superlattice material.

Not too big, not too small: Goldilocks analogy found in maze navigation

New research from the Okinawa Institute of Science and Technology Graduate University (OIST) has found a surprising randomness for how fluids choose their path around obstacles that depends on their spacing. This has important implications for a range of scenarios—from oil recovery and groundwater remediation, to understanding the movement of fluids through biological systems. The research was published in Physical Review Letters.

Modeling the brain during pain processing

The many different sensations our bodies experience are accompanied by deeply complex exchanges of information within the brain, and the feeling of pain is no exception. So far, research has shown how pain intensity can be directly related to specific patterns of oscillation in brain activity, which are altered by the activation and deactivation of the 'interneurons' connecting different regions of the brain. However, it remains unclear how the process is affected by 'inhibitory' interneurons, which prevent chemical messages from passing between these regions. Through new research published in EPJ B, researchers led by Fernando Montani at Instituto de Física La Plata, Argentina, show that inhibitory interneurons make up 20% of the circuitry in the brain required for pain processing.

Tracking cells with omnidirectional visible laser particles

Microlaser particles have emerged as unique optical probes for single-cell tracking. However, due to inherent directionality of laser emissions, cell tracking with laser particles suffers from frequent loss of cell traces. Recently, scientists at Harvard Medical School and Peking University placed omnidirectional visible laser particles into live cells, and demonstrated continuous spatial tracking of single cells. The technique will open new avenues for large-scale single-cell analysis in the study of cellular heterogeneity.

Air-guiding in solid-core optical waveguides: A solution for on-chip trace gas spectroscopy

Optical waveguides suspended in air are capable of beating free-space laser beams in light-analyte interaction even without complex dispersion engineering. This phenomenon was predicted more than 20 years ago, yet never observed in experiment.

Innovative mechanical system makes it easy to turn bedridden patients

It takes around five or six people and a considerable amount of effort to turn an intubated patient in a hospital bed. For patients in an artificial coma, this procedure is performed at least twice a day in order to improve patients' breathing and prevent bedsores. And now that intensive care units are filling up as a result of the pandemic, the problem is getting worse. A team comprising scientific assistants and a student, headed by Prof. Charles Baur at EPFL's Instant-Lab in Neuchâtel, have developed a simple system that allows just three people to turn a patient with little effort. It was tested by doctors and nurses at the La Source Clinic simulated hospital in Lausanne and the Geneva University Hospital (HUG) intensive care unit, and everyone involved was enthusiastic about the new device. It has been patented and is now ready for large-scale production.
