The Flying-V, an experimental aircraft that promises significantly greater fuel efficiency over more conventional commercial jet designs, is moving towards a larger, more detailed version since the scaled, 10-foot model took flight in 2020 in Germany.

The 315-passenger jet flies like other commercial airliners its size, according to recent tests, but is 20 percent more fuel efficient. Plus, it just looks a lot cooler.

A lethal bird flu outbreak that has been circling the globe since 2021 peaked in Japan this week, as an agriculture ministry official said on Tuesday the country plans to cull more than 10 million chickens at risk of exposure to the virus.

Flu is a common annual illness among wild birds yet the H5N1 strain now sweeping Japan is uniquely contagious and deadly. It poses such high risk to farmed birds, such as chickens and turkeys, that a single infection on a farm condemns the entire flock to be killed. As outbreaks in Japan have reached a record high, the cull is the largest ever planned for the yearly flu season that runs from October to May.

Around the globe, record-breaking death tolls due to the virus are becoming the norm. In the US, more states than ever before have reported instances of bird flu with an all-time high of nearly 58 million poultry affected as of January 2023.

As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving and accurate analytical tools has become increasingly critical—especially as the hunt for extraterrestrial life and habitable planets or moons continues.

A University of Maryland–led team developed a new instrument specifically tailored to the needs of NASA space missions. Their mini laser-sourced analyzer is significantly smaller and more resource efficient than its predecessors—all without compromising the quality of its ability to analyze planetary material samples and potential biological activity onsite. The team’s paper on this new device was published in the journal Nature Astronomy on January 16, 2023.

Weighing only about 17 pounds, the instrument is a physically scaled-down combination of two important tools for detecting signs of life and identifying compositions of materials: a pulsed ultraviolet laser that removes small amounts of material from a planetary sample and an Orbitrap analyzer that delivers high-resolution data about the chemistry of the examined materials.

Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition is enhanced by its so-called “occupation number,” an effect known as bosonic stimulation. The appearance of bosonic stimulation in light scattering processes was first predicted over three decades ago, yet directly observing it in experimental settings has so far proved challenging.

Researchers at the MIT-Harvard Center for Ultracold Atoms have recently observed bosonic enhanced light scattering in an ultracold gas for the first time. Their findings, published in Nature Physics, could open new exciting possibilities for the study of bosonic systems.

“For bosons, the transition rate into an already occupied quantum state is enhanced by its occupation number: the effect of bosonic stimulation,” Yu-Kun Lu, one of the researchers who carried out the study, told Phys.org.

Cambridge researchers have developed a new test that “fishes” for multiple respiratory viruses at once using single strands of DNA as bait and gives highly accurate results in under an hour.

The test uses DNA “nanobait” to detect the most common respiratory viruses —including influenza, rhinovirus, RSV and COVID-19—at the same time. In comparison, PCR (polymerase chain reaction) tests, while highly specific and highly accurate, can only test for a single virus at a time and take several hours to return a result.

While many common respiratory viruses have similar symptoms, they require different treatments. By testing for multiple viruses at once, the researchers say their test will ensure patients get the right treatment quickly and could also reduce the unwarranted use of antibiotics.

When searching for catalysts for the energy transition, materials consisting of at least five elements are considered highly promising. But there are theoretically millions of them—how do we identify the most powerful one?

A Bochum-based research team led by Professor Alfred Ludwig, head of the Materials Discovery and Interfaces Department (MDI), has succeeded in placing all possible combinations of five elements on a carrier in a single step. In addition, the researchers developed a method to analyze the electrocatalytic potential of each of the combinations in this micromaterial library in high throughput.

This is how they hope to speed up the search for potential catalysts by a considerable degree. The team from Ruhr University Bochum published its findings in the journal Advanced Materials.

For decades, transistors—the heart of computer chips—have been getting smaller and smaller. As a result, the electronic components in many devices can be made even more compact, faster and also more powerful. But is this development coming to a natural halt? The smaller the components, the greater the danger that individual defects in the atomic structure will significantly change the behavior of the component. This applies to the established silicon technology and novel nanotechnologies based on 2D materials.

At Vienna University of Technology (TU Wien), intensive work has been done on the physical description of this problem at the transistor level. Now the researchers are going a step further and looking at the influence of defects at the level of electronic circuits, which sometimes consist of several—sometimes even billions—of transistors. In some cases, individual transistors can operate outside the desired specification, but still perform well as part of a circuit consisting of several transistors. With this new approach at the circuit level, significant advances in miniaturization are still possible.

The study is published in the journal Advanced Materials.

An experimental campaign was conducted on the Säntis mountain in north-eastern Switzerland during the summer of 2021 with a high-repetition-rate terawatt laser. The guiding of an upward negative lightning leader over a distance of 50 m was recorded by two separate high-speed cameras.

A terawatt laser filament is shown to be able to guide lightning over a distance of 50 m in field trials on the Säntis mountain in the Swiss Alps.
