A supersonic drone that will be propelled by a revolutionary new engine has taken to the skies for the first time. When Venus Aerospace’s aircraft does go supersonic on a later date, it will be powered by a Rotating Detonation Rocket Engine (RDRE).

Supersonic drones may sound like something bleeding edge, but they’re surprisingly old hat as a basic concept. As far back as the early 1950s, the US Air Force was fielding remote-controlled supersonic jets for targets to test air defenses, as platforms for reconnaissance in dangerous areas, or as weapons armed with conventional or nuclear warheads.

However, the one thing they’ve all had in common over the past 75 years was a jet engine for propulsion to boost them past Mach 1. In recent years, advances in avionics, aerodynamics, and autonomous systems have allowed uncrewed aircraft to expand their roles, but at their heart, they were still jet propelled.

In an effort to bring clean, renewable energy to some of the world’s more remote islands — many of which are powered by old diesel generators — a pan-European consortium of seven companies has designed a device capable of turning seawater into electricity.

The Ocean Thermal Energy Conversion, or OTEC, technology consists of three main parts that are being built all over the world: a cold-water riser pipe, which is being fabricated in Austria, a cylindrical hull, which is being built in the Canary Islands (a Spanish autonomous community, where the OTEC will be assembled and tested), and a gimbal connection point.

Once the entire OTEC prototype is complete, it will be installed on the Oceanic Platform of the Canary Islands, a little under two miles off the coast. There, it will be tested in harsh ocean conditions for one year. The OTEC is designed to be disconnected if conditions get too harsh and moved closer to shore until the weather clears up.

CAMBRIDGE, Mass. — NASA has selected three companies to work on lunar rover concepts that would be offered as a service for Artemis lunar landings and scientific activities.

NASA announced April 3 it picked teams led by Intuitive Machines, Lunar Outpost and Venturi Astrolab for its Lunar Terrain Vehicle (LTV) Services contract. The contract covers work to design and develop rovers that would be used by astronauts on Artemis missions starting with Artemis 5 at the end of the decade. The rovers would be provided by the companies to NASA as a service, in much the same way the agency is procuring spacesuits and lunar landers.

While the primary purpose of the LTV will be to transport astronauts across the lunar surface, NASA expects to also teleoperate the rover, allowing it to perform scientific investigations when astronauts are not present. “Think of a hybrid of the Apollo-style lunar rover that was driven by our astronauts and an uncrewed mobile science platform,” said Vanessa Wyche, director of NASA’s Johnson Space Center, at a briefing to announce the contract selections.

Apple is reportedly exploring the development of ‘home robots’ as its next big venture.

According to Business Insider, tech giant Apple is shifting its focus towards a new area of development.

The pivot comes after a difficult period for Apple, with the company scrapping its plans to develop a self-driving car, which it had been working on for years.

Researchers at Tel Aviv University have developed a new treatment course for patients with metastasizing breast cancer, using medication already on the market.

Based on tissue samples from American and Israeli patients and using an animal model, the researchers from the Faculty of Medical and Health Sciences showed that a combination of existing drugs can hinder the spread of cancer to the bones, thereby improving the chances of survival.

More than 75 percent of patients with metastatic breast cancer see it spread to the bone.

The first patient to receive a kidney transplanted from a genetically modified pig has fared so well that he was discharged from the hospital on Wednesday, just two weeks after the groundbreaking surgery.

The transplant and its encouraging outcome represent a remarkable moment in medicine, scientists say, possibly heralding an era of cross-species organ transplantation.

Two previous organ transplants from genetically modified pigs failed. Both patients received hearts, and both died a few weeks later. In one patient, there were signs that the immune system had rejected the organ, a constant risk.

Summary: Researchers unveiled a novel approach to combat Alzheimer’s disease by activating microglia, the brain’s immune cells, to devour amyloid beta plaques, a hallmark of the condition. This study highlights the potential of using immunotherapy to not only tackle Alzheimer’s but also other neurodegenerative diseases characterized by harmful protein accumulations.

The team’s method involves using an antibody to stimulate microglia into clearing these plaques, offering a promising alternative to current treatments that directly target amyloid beta and might cause side effects like ARIA. This breakthrough paves the way for new therapeutic strategies that harness the immune system to fight the devastating effects of Alzheimer’s and possibly other diseases like Parkinson’s and ALS.

Analyzing and storing large amounts of data requires a lot of energy, so the future of technology might hold a different approach to data storage. At least, that is what Professor Søren Brunak from the University of Copenhagen thinks.

Brunak states that while Denmark is one of the best in the world at health data, analyzing and storing huge amounts of health data comes at a climate cost. “We have begun to consider the carbon footprint of bioinformatics and CO2 emissions resulting from data analysis,” he adds.
