At approximately 18:17 CET (17:17 UTC) on Wednesday, February 21, 2024, ESA’s ERS-2 satellite completed its atmospheric reentry over the North Pacific Ocean. No damage to property has been reported.

ESA’s second European Remote Sensing satellite, ERS-2, was launched almost 30 years ago, on April 21, 1995. Together with the almost-identical ERS-1, it provided invaluable long-term data on Earth’s land surfaces, ocean temperatures, ozone layer, and polar ice extent that revolutionized our understanding of the Earth system. It was also called upon to monitor and assist the response to natural disasters.

“The ERS satellites have provided a stream of data which has changed our view of the world in which we live,” said ESA’s Director of Earth Observation Programmes, Simonetta Cheli. “They have provided us with new insights on our planet, the chemistry of our atmosphere, the behavior of our oceans, and the effects of mankind’s activity on our environment – creating new opportunities for scientific research and applications.”

The U.S. Naval Research Laboratory (NRL), working together with Kansas State University, has announced the discovery of slab waveguides made from the two-dimensional material hexagonal boron nitride. This milestone has been documented in the journal Advanced Materials.

Two-dimensional (2D) materials are a class of materials that can be reduced to the monolayer limit by mechanically peeling the layers apart. The weak interlayer attractions, or van der Waals attraction, allows the layers to be separated via the so-called “Scotch tape” method. The most famous 2D material, graphene, is a semimetallic material consisting of a single layer of carbon atoms. Recently, other 2D materials including semiconducting transition metal dichalcogenides (TMDs) and insulating hexagonal boron nitride (hBN) have also garnered attention. When reduced near the monolayer limit, 2D materials have unique nanoscale properties that are appealing for creating atomically thin electronic and optical devices.

POSTECH’s new metasurface display technology projects angle-dependent holograms, enhancing virtual and augmented reality experiences.

The expression “flawless from every angle” is commonly used to characterize a celebrity’s appearance. This doesn’t simply imply that they appear attractive from a specific viewpoint, but rather that their appeal remains consistent and appealing from various angles and perspectives. Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurface to fabricate angle-dependent holograms with multiple functions, capturing significant interest within the academic community.

For years, researchers have dedicated themselves to developing methods that can effectively and economically break down plant materials, enabling their transformation into valuable bioproducts that enhance our daily lives.

Bio-based fuels, detergents, nutritional supplements, and even plastics are the result of this work. And while scientists have found ways to degrade plants to the extent needed to produce a range of products, certain polymers such as lignin, which is a primary ingredient in the cell wall of plants, remain incredibly difficult to affordably break down without adding pollutants back into the environment. These polymers can be left behind as waste products with no further use.

A specialized microbial community composed of fungus, leafcutter ants, and bacteria is known to naturally degrade plants, turning them into nutrients and other components that are absorbed and used by surrounding organisms and systems. But identifying all components and biochemical reactions needed for the process remained a significant challenge—until now.

Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator – a specific type of quantum computer – could lead to new discoveries about how the world works at the smallest scales. Quantum scientist Natalia Chepiga from Delft University of Technology has developed a guide on how to upgrade these machines so that they can simulate even more complex quantum systems. The study is now published in Physical Review Letters.

“Creating useful quantum computers and quantum simulators is one of the most important and debated topics in quantum science today, with the potential to revolutionize society,” says researcher Natalia Chepiga. Quantum simulators are a type of quantum computer, Chepiga explains: “Quantum simulators are meant to address open problems of quantum physics to further push our understanding of nature. Quantum computers will have wide applications in various areas of social life, for example in finances, encryption, and data storage.”

An international team of scientists has made a new discovery that may help to unlock the microscopic mystery of high-temperature superconductivity and address the world’s energy problems.

In a paper published in the journal Nature, Swinburne University of Technology’s Associate Professor Hui Hu collaborated with researchers at the University of Science and Technology of China (USTC) in a new experimental observation quantifying the pseudogap pairing in a strongly attractive interacting cloud of fermionic lithium atoms.

Researchers from the University of Illinois Chicago and Harvard University have created an antibiotic that may provide medicine a new tool to combat bacteria resistant to drugs and the illnesses they trigger.

The antibiotic, cresomycin, described in Science, effectively suppresses pathogenic bacteria that have become resistant to many commonly prescribed antimicrobial drugs.

The promising novel antibiotic is the latest finding for a longtime research partnership between the group of Yury Polikanov, associate professor of biological sciences at UIC, and colleagues at Harvard. The UIC scientists provide critical insights into cellular mechanisms and structure that help the researchers at Harvard design and synthesize new drugs.

I just used AI in two films that are going to be announced soon. That kept me out of makeup for hours. In post and on set, I was able to use this AI technology to avoid ever having to sit through hours of aging makeup.

How are you thinking about approaching the threat that AI poses to certain job categories at your studio and on your productions?
