A new VTOL capability for the Blackjack drone will scrap the launcher and make the system more expeditionary.

The French Armament General Directorate (DGA) announces that the Camcopter S100 VTOL UAV is now fully integrated with French Navy Mistral-class LHD Dixmude, stressing that for the first time in Europe, a rotary wing UAV is fully operational and connected to the combat system of a warship.

Researchers at the US Department of Energy (DOE)’s Oak Ridge National Laboratory (ORNL) are developing a nuclear reactor core using 3D printing.

As part of its Transformational Challenge Reactor (TCR) Demonstration Program, which aims to build an additively manufactured microreactor, ORNL has refined its design of the reactor core, while also scaling up the additive manufacturing process necessary to build it. Additionally, the researchers have established qualification methods to confirm the consistency and reliability of the 3D printed components used in creating the core.

“The nuclear industry is still constrained in thinking about the way we design, build and deploy nuclear energy technology,” comments ORNL Director Thomas Zacharia.

The remains of a giant segment of a Chinese rocket crash-landed in the Atlantic Ocean this week, representing the most significant uncontrolled descent of a piece of human-made space debris in decades.

The core stage of a Chinese Long March 5B (CZ–5B) rocket, which was successfully launched on May 5, spent several days in orbit as part of its mission, before re-entering Earth’s atmosphere and falling to Earth, splashing down in ocean waters off the west coast of Mauritania in northwest Africa.

The descent, which was eventually confirmed by the 18th Space Control Squadron, a unit of the US Air Force, was notable not just for its huge mass, but also for the extent of the window of uncontrolled descent, which had space-object trackers guessing just where and when the out-of-control rocket would eventually land.

Universal quantum computation¹ is striking for its unprecedented capability in processing information, but its scalability is challenging in practice because of the inevitable environment noise. Although quantum error correction (QEC) techniques^{2,3,4,5,6,7,8} have been developed to protect stored quantum information from leading orders of error, the noise-resilient processing of the QEC-protected quantum information is highly demanded but remains elusive⁹. Here, we demonstrate phase gate operations on a logical qubit encoded in a bosonic oscillator in an error-transparent (ET) manner. Inspired by refs. ^10,11, the ET gates are extended to the bosonic code and are able to tolerate errors on the logical qubit during gate operations, regardless of the random occurrence time of the error. With precisely designed gate Hamiltonians through photon-number-resolved a.c. Stark shifts, the ET condition is fulfilled experimentally. We verify that the ET gates outperform the non-ET gates with a substantial improvement of gate fidelity after an occurrence of the single-photon-loss error. Our ET gates in superconducting quantum circuits can be readily extended to multiple encoded qubits and a universal gate set is within reach, holding the potential for reliable quantum information processing.

The weird world of quantum physics is being harnessed for some fascinating use cases. In the latest example, physicists have developed and demonstrated a “quantum radar” prototype that uses the quantum entanglement phenomenon to detect objects, a system which could eventually outperform conventional radar in some circumstances.

Quantum entanglement describes the bizarre state where two particles can become linked so tightly that they seem to communicate instantly, no matter how far apart they are. Measuring the state of one particle will instantly change the state of the other, hypothetically even if it’s on the other side of the universe. That implies that the information is moving faster than the speed of light, which is thought to be impossible – and yet, it’s clearly and measurably happening. The phenomenon even unnerved Einstein himself, who famously described it as “spooky action at a distance.”

If you are interested in age reversal, and you haven’t read Dr David Sinclair (Harvard Medical School) yet, then I’d recommend this research paper.

“Excitingly, new studies show that age-related epigenetic changes can be reversed with interventions such as cyclic expression of the Yamanaka reprogramming factors. This review presents a summary of epigenetic changes that occur in aging, highlights studies indicating that epigenetic changes may contribute to the aging process and outlines the current state of research into interventions to reprogram age-related epigenetic changes.”

The aging process results in significant epigenetic changes at all levels of chromatin and DNA organization. These include reduced global heterochromatin, nucleosome remodeling and loss, changes in histone marks, global DNA hypomethylation with CpG island hypermethylation, and the relocalization of chromatin modifying factors. Exactly how and why these changes occur is not fully understood, but evidence that these epigenetic changes affect longevity and may cause aging, is growing. Excitingly, new studies show that age-related epigenetic changes can be reversed with interventions such as cyclic expression of the Yamanaka reprogramming factors. This review presents a summary of epigenetic changes that occur in aging, highlights studies indicating that epigenetic changes may contribute to the aging process and outlines the current state of research into interventions to reprogram age-related epigenetic changes.

Researchers at Northwestern University have developed a garment designed to confuse digital surveillance algorithms into thinking you don’t exist.

In a little over a month, a team of physicists and engineers from around the world took a simplified ventilator design from concept all the way through approval by the U.S. Food and Drug Administration. This major milestone marks the ventilator as safe for use in the United States under the FDA’s Emergency Use Authorization, which helps support public health during a crisis.

The Mechanical Ventilator Milano, or MVM, is the brainchild of physicist Cristiano Galbiati. The Gran Sasso Science Institute and Princeton University professor, who normally leads a dark matter experiment in Italy called DarkSide-20k, found himself in lockdown in Milan, a city hit hard by COVID-19. Hearing reports of ventilator shortages and wanting to help, Galbiati reached out to fellow researchers to develop a ventilator with minimal components that could be quickly produced using commonly available parts.

“The sense of crisis was palpable, and I knew the availability of ventilators was critical,” said Galbiati, who obtained his Ph.D from the University of Milan. “We had been doing some complicated projects in physics that required working with gases, and I thought it our duty to find a way to push oxygen into the lungs of patients.”
