The researchers believe this will help build a more predictive model to prevent future incidents of dangerous clear air turbulence.

Besides poor visibility, icing, and bird, mid-flight turbulence is one of the most common causes of aircraft accidents.

Clear air turbulence (CAT) is a truly significant aviation hazard. It’s invisible, mostly cloud-free, hard to predict, and the most dangerous type of turbulence. It can be caused by jet streams, gravity waves, or cumulus clouds.

Over the past decades, physicists and engineers have been trying to develop various technologies that leverage quantum mechanical effects, including quantum microscopes. These are microscopy tools that can be used to study the properties of quantum particles and quantum states in depth.

Researchers at Silicon Quantum Computing (SQC)/UNSW Sydney and the University of Melbourne recently created a new solid-state quantum microscope that could be used to control and examine the wave functions of atomic qubits in silicon. This microscope, introduced in a paper published in Nature Electronics, was created combining two different techniques, known as ion implantation and atomic precision lithography.

“Qubit device operations often rely on shifting and overlapping the qubit wave functions, which relate to the spatial distribution of the electrons at play, so a comprehensive knowledge of the latter provides a unique insight into building quantum circuits efficiently,” Benoit Voisin and Sven Rogge, two researchers who carried out the study, told Phys.org.

Footage of thousands of tiny metal spheres set jiggling in a shallow tray has revealed an arrangement of particles once considered impossible.

A team of physicists from the University of Paris-Saclay in France has observed an unusual combination of order and chaos known as a ‘quasicrystal’ emerging spontaneously in a granular material on a millimeter-scale for the first time.

If there is beauty in order, crystals are the very manifestation of elegance and attraction.

2020 underwater base.

Aquanaut Fabien Cousteau — grandson of famed ocean explorer Jacques-Yves Cousteau — has announced plans to build the world’s biggest underwater base for scientific research.

He calls the facility “Proteus” and envisions it being the ocean equivalent of the International Space Station — a place where scientists from across the globe can work together to solve the world’s biggest problems, from climate change to world hunger.

A new study explores how artificial intelligence can not only better predict new scientific discoveries but can also usefully expand them. The researchers, who published their work in Nature Human Behaviour, built models that could predict human inferences and the scientists who will make them.

The authors also built models that avoided human inference to generate scientifically promising “alien” hypotheses that would not likely be considered until the distant future, if at all. They argue that the two demonstrations—the first allowing for the acceleration of human discovery, while the second identifies and passes over its blind spots—means that a human-aware AI would allow for movement beyond the contemporary scientific frontier.

“If you build in awareness to what people are doing, you can improve prediction and leapfrog them to accelerate science,” says co-author James A. Evans, the Max Palevsky Professor in the Department of Sociology and director of the Knowledge Lab. “But you can also figure out what people can’t currently do, or won’t be able to do for decades or more into the future. You can augment them by providing them that kind of complementary intelligence.”

Nearly 200 separate remains, including those of the late Star Trek creator and two of the show’s cast members, will be part of an inaugural deep space mission to permanently orbit the sun as their final resting place.

Celestis, a company that has been promoting space burial service since 1994, will launch the first-of-its-kind memorial spaceflight to take place in nearly 30 years.

Advantageously, the fabrication of OECTs, in particular of the conductive channel, is compatible with solution-based fabrication methods and additive manufacturing, enabling cost-efficient manufacturing and rapid prototyping on flexible substrates¹⁰. This opens new possibilities in terms of the combination of materials that can be used in the manufacturing of OECTs, in particular the use of degradable materials. Degradable electronics refer to electronic systems and components that can degrade in an environment of interest spontaneously, in a controlled amount of time, and without releasing byproducts that are harmful to that environment¹⁸. With concerning amounts of electronic waste being generated, as well as exploding numbers of connected Internet of Things (IoT) devices¹⁹, there is growing interest in transient electronic systems with a service life of a few days to a few months. Although advances have been made in the manufacturing of fully degradable functional devices, i.e. antennas²⁰, batteries²¹ and physical as well as environmental sensors^22,23, investigations into degradable biosensors remain relatively limited²⁴.

Advances have been made in proposing new materials for the OECT terminals, in particular the gate electrode, as its properties play a key role in modulating the transistor’s behavior. While Ag/AgCl gates offer the advantage of being non-polarizable, Au gates present little electrochemical activity in the range of voltages typical for OECT-based biosensing. Au and PEDOT: PSS gates have been explored for OECT-based biosensors, with the advantage of expanding the possibilities for bio-functionalizing the gate electrode^6,25. PEDOT: PSS gates and contacts have been investigated, simplifying notably their manufacturing²⁶. An all-PEDOT: PSS OECT was presented and shown to measure dopamine concentrations reliably and specifically²⁷. Various forms of carbon have also been investigated for the realization of gate electrodes for OECTs⁸. Activated carbon gates, for example, showed increased drain current modulation due to the large specific surface area of the carbon material⁹. Recently, screen-printed carbon-gated OECTs were shown to be suitable for the detection of uric acid after functionalization of the carbon gate with platinum and Uricase²⁸. Transient or recyclable materials such as paper²⁶ have been proposed as substrates for OECTs. Polylactic acid (PLA)²⁴ and Poly(lactic-co-glycolic acid)²⁹ (PLGA) have been studied as degradable substrates for OECTs³⁰, as well as diacetate cellulose³¹. These studies, however, relied on non-degradable contacts for the operation of the printed OECTs. More recently, Khan et al.³² proposed a fully printed OECT on cellulose acetate (CA) for the selective detection of glucose. The OECT is made of degradable materials and CA is a biocompatible material that is suitable as a substrate for transient biosensors.

In this work, we present disposable and biocompatible OECTs based on carbon, PEDOT: PSS and PLA as substrate. Challenges in the fabrication of transient electronic devices come from the low-temperature tolerance¹⁸ of biopolymeric substrates and reaching adhesion of the PEDOT: PSS channel material on the biopolymer³³, which is often deposited from an aqueous solution. A fully additive fabrication process is developed to address these challenges, leveraging screen and inkjet printing. The influence of the gate material choice, as well as the gate geometry, are studied, and these parameters are optimized for the fabrication of transient OECTs for ions and metabolite sensing. The transistor characteristics of the devices as well as their sensing behavior and reproducibility are characterized. Finally, the degradable OECTs are integrated with highly conductive transient zinc metal traces, which are of interest for interconnection with other degradable electronic circuits and could allow, for example, the wireless operation of the biochemical chemical sensors³⁴.

Globally, atherosclerotic cardiovascular disease (ASCVD) is the primary cause of illness and death and is much more common in with type 2 diabetes mellitus (T2DM) patients than non-diabetic individuals. Nevertheless, for approximately ten years, the identification of distinct prognostic risk biomarkers remains challenging.

In a recent study posted to the preprint server Research Square while under review for publication in Cardiovascular Diabetology, researchers investigate the prognostic value of serum proprotein convertase subtilisin/kexin type 9 (PCSK9) levels in T2DM patients to predict all-cause mortality and major adverse cardiovascular events (MACE).
