DYNAMO achieves first observation of the 'charge separation effect'

The University of Michigan has successfully demonstrated the "charge separation effect," predicted over a decade ago, which has important potential for direct conversion of light to electricity without the thermodynamic losses typical of photovoltaic (solar cell) technology. The results are expected to be important to future developments in ultrafast switching, nanophotonics, and nonlinear optics as well.

Reading out qubits like toppling dominoes: A new scalable approach towards the quantum computer

Creating a powerful, large-scale quantum computer depends on a clever design such that many qubits (the building block of a quantum computer) can be controlled and read out. Researchers at QuTech, a collaboration between TU Delft and TNO, have invented a new readout method that is an important step forward on the road towards such a large-scale quantum computer. They have published their findings in Nature Communications today.

Breaking through the resolution barrier with quantum-limited precision

Researchers at Paderborn University have developed a new method of distance measurement for systems such as GPS, which achieves more precise results than ever before. Using quantum physics, the team led by Leibniz Prize winner Professor Christine Silberhorn has successfully overcome the so-called resolution limit, which causes the 'noise' we may see in photos, for example. Their findings have just been published in the academic journal Physical Review X Quantum (PRX Quantum).

Machine learning improves particle accelerator diagnostics

Operators of the primary particle accelerator at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility are getting a new tool to help them quickly address issues that can prevent it from running smoothly. A new machine learning system has passed its first two-week test, correctly identifying glitchy accelerator components and the type of glitches they're experiencing in near-real-time.

Evolving the surgical microscope

A clear view of anatomical structures is vital for the success of surgery—especially in microsurgery where narrow anatomical cavities or proximity to vulnerable organs and tissues can pose significant risks to patient health. The surgical microscope has evolved to become a powerful tool for improving surgical visualization.

Superflare detected on an ultracool star

Using Xinglong observatory's Ground-based Wide Angle Cameras (GWAC), astronomers from China and France have detected a new superflare of an ultracool star known as SDSS J013333.08+003223.7. The newly found event, designated GWAC 181229A, appears to be one of the most powerful flares on ultracool stars so far discovered. The finding is reported in a paper published December 28 on

Remote sensing data sheds light on when and how asteroid Ryugu lost its water

Last month, Japan's Hayabusa2 mission brought home a cache of rocks collected from a near-Earth asteroid called Ryugu. While analysis of those returned samples is just getting underway, researchers are using data from the spacecraft's other instruments to reveal new details about the asteroid's past.

SETI: New signal excites alien hunters – here's how we could find out if it's real

The US$100m (£70m) Breakthrough Listen Initiative, founded by Russian billionaire, technology and science investor Yuri Milner and his wife Julia, has identified a mysterious radio signal that seems to come from the nearest star to the Sun—Proxima Centauri. This has generated a flood of excitement in the press and among scientists themselves. The discovery, which was reported by The Guardian but has yet to be published in a scientific journal, may be the search for extraterrestrial intelligence's (SETI) first bona fide candidate signal. It has been dubbed Breakthrough Listen Candidate 1 or simply BLC-1.

Digital Sky Survey maps the entire sky, providing new data to astronomers

The fifth generation of the Sloan Digital Sky Survey is collecting data about our universe for Vanderbilt University astronomers and other project members to use to explore the formation of distant galaxies and supermassive black holes, and to map the Milky Way.

Chitrakar: A system that can transform images of human faces into drawings

Researchers at the TCS Robotics Research Lab in India have recently developed an artificial intelligence (AI) system that can automatically convert an image of a person's face into a recognizable non-self-intersecting loop, known as a Jordan curve. Subsequently, this Jordan curve can be used to produce realistic drawings of the person in the original image, using a robotic hand.

Qualcomm's Snapdragon 480 SoC to bring 5G to low-cost phones

As 5G-enabled phones secured their spot as major players in smartphone technology in 2020, access to this latest functionality has been limited to higher-end phones. But things are about to change, as Qualcomm announced today the development of the Snapdragon 480 5G Mobile Platform, which is expected to usher in a new wave of low-cost smartphones featuring cutting-edge features of the latest wireless standard.

Researchers compute turbulence with artificial intelligence

For the first time, researchers at ETH Zurich have successfully automated the modeling of turbulence by combining fluid mechanics with artificial intelligence. Their project relies on fusing reinforcement learning algorithms with turbulent flow simulations on the CSCS supercomputer Piz Daint.

Multifunctional lens sensor system could revolutionize smart contacts

The enormous impact of the recent COVID-19 pandemic, together with other diseases or chronic health risks, has significantly prompted the development and application of bioelectronics and medical devices for real-time monitoring and diagnosing health status. Among all these devices, smart contact lenses attract extensive interests due to their capability of directly monitoring physiological and ambient information. Smart contact lenses equipped with high sensitivity sensors would open the possibility of a non-invasive method to continuously detect biomarkers in tears. They could also be equipped with application-specific integrated circuit chips to further enrich their functionality to obtain, process and transmit physiological properties, manage illnesses and health risks, and finally promote health and wellbeing. Despite significant efforts, previous demonstrations still need multistep integration processes with limited detection sensitivity and mechanical biocompatibility.

On the road to invisible solar panels: How tomorrow's windows will generate electricity

Five years after the Paris climate agreement, all eyes are on the world's progress on the road to a carbon-free future. A crucial part of this goal involves the energy transition from fossil fuels to renewable sources, such as sun, water, wind and wave energy. Among those, solar energy has always held the highest hope in the scientific community, as the most reliable and abundant energy source on Earth. In recent decades, solar cells have become cheaper, more efficient, and environment friendly. However, current solar cells tend to be opaque, which prevents their wider use and integration into everyday materials, constrained to being lined up on roofs and in remote solar farms.
