Flying cars are becoming closer to reality than what sci-fi movies may lead you to believe. Another electric flying car “took flight” this week in the US. CEO Doron Merdinger of Miami-based Doroni Aerospace successfully piloted a two-seater personal vertical takeoff and landing (eVTOL) aircraft that fits in your garage.

Electric flying cars are all of a sudden taking the US by storm. Last month, California-based Alef Aeronautics revealed its 100% electric flying car, “Model A,” the first of its kind to receive legal approval to fly from the US government.

According to Alef, the Model A has a 200-mile driving range and can fly for 110 miles. The company says it had gathered over 440 orders for its $300K electric flying car within three months.

Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called “impossible early galaxy problem.”

The work is published in the journal Monthly Notices of the Royal Astronomical Society.

“Our newly-devised model stretches the galaxy formation time by a several billion years, making the 26.7 billion years old, and not 13.7 as previously estimated,” says author Rajendra Gupta, adjunct professor of physics in the Faculty of Science at the University of Ottawa.

The future of electronics will be based on novel kinds of materials. Sometimes, however, the naturally occurring topology of atoms makes it difficult for new physical effects to be created. To tackle this problem, researchers at the University of Zurich have now successfully designed superconductors one atom at a time, creating new states of matter.

What will the computer of the future look like? How will it work? The search for answers to these questions is a major driver of basic physical research. There are several possible scenarios, ranging from the further development of classical electronics to neuromorphic computing and quantum computers.

The common element in all these approaches is that they are based on novel physical effects, some of which have so far only been predicted in theory. Researchers go to great lengths and use state-of-the-art equipment in their quest for new quantum materials that will enable them to create such effects. But what if there are no suitable materials that occur naturally?

Now that Virgin Galactic has flown its first commercial spaceflight, it’s ready to take civilians aboard. The company now expects to launch its first private passenger flight, Galactic 2, as soon as August 10th. Virgin isn’t yet revealing the names of everyone involved, but there will be three passengers alongside the usual crew. You can watch a live stream on the company website.

The inaugural commercial flight, Galactic 1, flew in late June. However, all three passengers were Italian government workers (two from the Air Force and one research council member) conducting microgravity studies. While it’s not clear what 02’s civilian crew will do, they can be tourists this time around.

The firm has been ramping up its operations in recent months after numerous delays from previous years. While Galactic 2 is just Virgin’s seventh spaceflight of any kind, it’s the third in 2023. The company says it’s establishing a “regular cadence” of flights, and you can expect them to become relatively routine if this voyage goes as planned.

It’s one of the biggest conferences of the year that almost no one is allowed to go to.

Allen & Co.’s annual conference in Sun Valley, Idaho, often referred to as “summer camp for billionaires,” is a who’s who of the biggest players in media and tech. This year’s attendees include Disney’s Bob Iger, Warner Bros. Discovery’s David Zaslav, Apple’s Tim Cook, and OpenAI’s Sam Altman.

The event even got the “Succession” treatment.

Electronic warfare systems are now able to jam precision guided weapons.

In the midst of ongoing conflict, Ukrainian forces are leveraging US-supplied glide bombs to their advantage. This video delves into the use of two distinct glide bombs: the GLSDB (Ground-Launched Small Diameter Bomb) and the JDAM-ER (Joint Direct Attack Munition-Extended Range). However, these American-made guided weapons are facing challenges due to Russia’s electronic interference, impacting their precision and effectiveness.

Despite the initial success of the HIMARS system in Ukraine’s counteroffensive in September 2022, recent reports suggest that Russian electronic jammers have disrupted the system’s GPS-guided targeting, leading to missed targets. The stakes are high as Ukraine heavily relies on HIMARS to target Russian logistical and military infrastructure.

The immune system is one of the most complex parts of our body. It keeps us healthy by getting rid of parasites, viruses or bacteria, and by destroying damaged or cancer cells. One of its most intriguing abilities is its memory: upon first contact with a foreign component (called antigens) our adaptive immune system takes around two weeks to respond, but responses afterwards are much faster, as if the cells remembered the antigen. But how is this memory attained?

In a recent publication, a team of researchers coordinated by Dr. Ralph Stadhouders, from Erasmus MC, and Dr. Gregoire Stik, Group Leader at the Josep Carreras Leukemia Research Institute, provides new clues on immune memory using state-of-the-art methodologies.

In their research paper, published in the journal Science Immunology, the first-author Anne Onrust-van Schoonhoven and colleagues compared the response of immune cells that had never been in contact with an antigen (called naïve cells) with cells previously exposed to antigen () and sort of knew it. They focused on the differences in the epigenetic control of the cellular machinery and the nuclear architecture of the cells, two mechanisms that could explain the quick activation pattern of memory cells.
