A lot of hurdles remain before the emerging technology of self-driving personal and commercial vehicles is common, but transportation researchers at The University of Alabama developed a promising, inexpensive system to overcome one challenge: GPS hacking that can send a self-driving vehicle to the wrong destination.

Initial research shows a self-driving vehicle can use already installed sensors to detect traveling the wrong route when passengers are unaware of the change, thwarting an attempt to spoof the GPS signal to the vehicle, according to findings outlined in recently published papers in the IEEE Transactions on Intelligent Transportation Systems and Transportation Research Record: Journal of the Transportation Research Board.

Relying on software code and in-vehicle sensors already part of the self-driving system would be cheaper for consumer and commercial vehicles to deny the hacked directions used to steer cargo or people away from their intended destination, said Dr. Mizanur Rahman, assistant professor of civil, construction and environmental engineering and affiliate researcher with the Alabama Transportation Institute.

A sustained, stable experiment is the latest demonstration that nuclear fusion is moving from being a physics problem to an engineering one.

NASA released an impressive desktop app some years back called “NASA’s Eyes Visualization,” which allowed you to check out the solar system, along with all the spacecraft exploring it. But who installs programs anymore? It graduated to the web recently, and now it has an updated interface and tools. Simply head to the “Eyes on the Solar System” site on your device of choice, and start exploring.

The main interface of the new site is simply the orbits of the planets, color-coded with highlights to show you their current positions. The layout is accurate for the current time, but you can use either buttons or the slider at the bottom to speed up or reverse time. It goes as high or as low as three years per second. You have to figure this revamp was supposed to coincide with NASA’s Artemis program, but that’s taking a bit longer than expected to get off the ground.

In addition to the clickable overview of the solar system, there are several suggested “points of interest” on the side of the screen. These are all along the same lines as the Eyes on the Solar System engine, but some (like the Perseverance landing simulation) load on a separate page.

The concept or idea of a multiverse fascinates physicists’ as much as sci-fi fans, but if science was able to prove it exists, could every type of universe within it actually be predicted? The late Stephen Hawking believed there was a way to shed light on this strangest cosmic mystery.

Hawking’s final paper, published in the journal High-Energy Physics revisits one of his earlier (and no less mind-blowing) theories. The “no-boundary proposal” considers Einstein’s suggestion that the pre-Big Bang universe was a singularity, an extremely dense and hot micro-speck of matter where the laws of physics didn’t apply. Hawking speculated that time as we know it was nonexistent in this singularity, which had no beginning and no end—infinite and spherical rather than finite and linear. The embryonic universe is thought to have expanded rapidly and spawned parallel worlds during a period known as cosmic inflation.

NASA is trying to pull a rabbit out of the hat to launch Artemis I this month. Watch to hear about this and other launch options in work. The main driver is getting waivers from range control on the Flight Termination System (FTS). Find out why the last attempt was scrubbed. The SpaceX Starship engine test campaign is also covered in this video after discussions of the advantages and disadvantages of using hydrogen fuels.

Assistant Professor Ariel Furst and her colleagues are looking to DNA to help guide the process.

Carbon dioxide (CO₂) is a major contributor to climate change and a significant product of many human activities, notably industrial manufacturing. A major goal in the energy field has been to chemically convert emitted CO₂ into valuable chemicals or fuels. But while CO₂ is available in abundance, it has not yet been widely used to generate value-added products. Why not?

The reason is that CO₂ molecules are highly stable and therefore not prone to being chemically converted to a different form.

Apple’s new iPhones — the iPhone 14 and iPhone 14 Plus — won’t have physical SIM cards. The company announced the nugget at its event in Cupertino today, revealing that eSIM will be the only way the iPhone 14 series authenticates with wireless carriers — at least in the U.S.

ESIM lets you change a wireless carrier, data or service plan through software rather than having to swap a physical SIM card. It’s hardly a new technology, but it’s only within the last few years that eSIM has become more common on mainstream mobile devices.

Apple said that major carriers including T-Mobile, Verizon and AT&T will provide resources to assist with eSIM-related questions, service upgrades and changes.

Manas Bhatia has a bold vision of the future — one where residential skyscrapers covered in trees, plants and algae act as “air purification towers.” In a series of detailed images, the New Delhi-based architect and computational designer has brought the idea to life. His imagined buildings are depicted rising high above a futuristic metropolis, their curved forms inspired by shapes found in nature.

But the pictures were not entirely of his own imagination.

For his conceptual project, “AI x Future Cities,” Bhatia turned to an artificial intelligence imaging tool, Midjourney, that generates elaborate pictures based on written prompts.
