CAPE CANAVERAL, Fla. (AP) — The world now has stunning new photos of this week’s asteroid strike, the first planetary defense test of its kind.
NASA on Thursday released pictures of the dramatic event taken by the Hubble and Webb space telescopes.
A few hours later, SpaceX joined NASA in announcing that they’re studying the feasibility of sending a private mission to Hubble, potentially led by a billionaire, to raise the aging telescope’s orbit and extend its life.
Hurricane Ian made landfall on Florida’s west coast Wednesday afternoon as a powerful Category 4 storm.
Regent has released video of its remarkable Seaglider prototype in flight testing. The first machine to combine the efficiency advantages of ground effect and hydrofoiling in a single design, it promises revolutionary speed and range in coastal areas.
Wing-in-ground effect (WIG) aircraft such as the Soviet-era Ekranoplan have shown promise in the past, but they’re yet to take off, so to speak, as a mainstream form of transport. These low-flying birds ride on a cushion of air between their wings and the surface, which gives them a significant lift and efficiency boost over regular planes flying higher in the air – as long as they stay within their own wingspan of the surface beneath. This extreme altitude restriction means that while ground-effect aircraft could fly over land, it’s too dangerous for regular operations, and they typically stay over water.
The numbers haven’t been attractive enough to date, but the era of electrification brings a set of new incentives to the game. Electric boats are struggling to prove their worth; batteries simply don’t hold enough energy to push through the tough medium of water for long distances. Early electric aircraft struggle to deliver useful range with a decent number of passengers on board, too. Regent looked at this, and saw a situation where the efficiency of the old ground-effect vehicle could give it a genuine commercial advantage, if paired with another, more recent technology.
Hurricane researchers sent a marine drone into Hurricane Fiona, where it captured intense footage of the tropical storm. The research drone will help scientists better understand how tropical storms rapidly intensify.
Few human injuries are as catastrophic as those to the spine. An accident, disease or act of violence affecting the spine can result in poor function – even paralysis – almost anywhere in the body.
The spinal column is enormously complex, with limited capacity for regeneration and any health implications are usually long-term and chronic.
While there is no known way to repair a spinal cord injury (SCI), scientists may be on the cusp of some important breakthroughs. New approaches are being taken to reverse the nerve damage, with some researchers attempting to reshape the architecture of the spinal cord using materials engineered in the laboratory.
Have you ever desired to possess shoes like in the Back to Future movie? The shoes that tie the laces to fit the feet…
Well, it may not be exactly the same thing, but German company WertelOberfell seems to have managed to create 3D-printed shoes that adapt to your feet.
The existing jacket can perform one logical operation per second, compared to the more than a billion operations per second typical of a home computer, says Preston. In practice, this means the jacket can only execute short command sequences. Due to the speed of the logic, along with some other engineering challenges, Zhang says he thinks it’ll take five to 10 years for these textile-based robots to reach commercial maturity.
In the future, Preston’s team plans to do away with the carbon dioxide canister, which is impractical. (You have to refill it like you would a SodaStream.) Instead, his team wants to just use ambient air to pump up the jacket. As a separate project, the team has already developed a foam insole for a shoe that pumps the surrounding air into a bladder worn around the waist when the wearer takes a step. They plan to integrate a similar design into the jacket.
Preston also envisions clothing that senses and responds to the wearer’s needs. For example, a sensor on a future garment could detect when the wearer is beginning to lift their arm and inflate without any button-pressing. “Based on some stimulus from the environment and the current state, the logic system can allow the wearable robot to choose what to do,” he says. We’ll be waiting for this fashion trend to blow up.
Initial findings of the Super Heavy Element Factory—an atom smasher in Russia—reveal details about some of the heaviest known elements.
A physicist’s do-it-yourself art project makes vibrant images with a pair of polarizers and carefully placed layers of transparent tape.
When the COVID-19 pandemic shut down universities and offices across the world in spring 2020, finding new hobbies to stave off fear (and boredom) became paramount. While some took up cross-stitch or a new stretching routine, Aaron Slepkov, a photonics researcher at the University of Trent in Peterborough, Canada, turned to a physics-inspired art form called polage to occupy his time.
Polage, or polarization-filtered coloration, as Slepkov calls it, is a kind of collage that uses polarizers and thin films to create brightly colored artworks that transform depending on how you look at them. This metamorphosis is made possible by birefringence, an optical property of certain materials that changes the polarization state of transmitted light. Examples of birefringent materials include ice, calcite crystals, cellophane film, and transparent tape.

Researchers create the most realistic rogue waves to date, showing dynamics that follow those expected for extreme waves in more idealized systems.
