Engineers use artificial intelligence to capture the complexity of breaking waves

Posted by in categories: information science, robotics/AI

Waves break once they swell to a critical height, before cresting and crashing into a spray of droplets and bubbles. These waves can be as large as a surfer’s point break and as small as a gentle ripple rolling to shore. For decades, the dynamics of how and when a wave breaks have been too complex to predict.

Now, MIT engineers have found a new way to model how waves break. The team used machine learning along with data from wave-tank experiments to tweak equations that have traditionally been used to predict wave behavior. Engineers typically rely on such equations to help them design resilient offshore platforms and structures. But until now, the equations have not been able to capture the complexity of breaking waves.

The updated model made more accurate predictions of how and when waves break, the researchers found. For instance, the model estimated a wave’s steepness just before breaking, and its energy and frequency after breaking, more accurately than the conventional wave equations.

Japanese rail company rolls out VR-piloted Gundam robot worker

Posted by in categories: robotics/AI, transportation, virtual reality

The West Japan Rail Company has released video of its new humanoid heavy equipment robot. Mounted on the end of a crane, this gundam-style robot torso mimics the arm and head motions of a human pilot, who sees through the robot’s eyes via VR goggles.

The key objectives here, according to the company, are “to improve productivity and safety,” enabling workers to lift and naturally manipulate heavy equipment around the rail system without exposing them to the risk of electric shocks or falling.

The robot’s large torso is mounted to a hydraulic crane arm, which rides around the rail system on a specially braced rail car, putting down stabilizing legs when it’s time to get to work.

Long-awaited accelerator ready to explore origins of elements

Posted by in categories: nuclear energy, physics

The Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU) in East Lansing had a budget of $730 million, most of it funded by the US Department of Energy, with a $94.5 million contribution from the state of Michigan. MSU contributed an additional $212 million in various ways, including the land. It replaces an earlier National Science Foundation accelerator, called the National Superconducting Cyclotron Laboratory (NSCL), at the same site. Construction of FRIB started in 2014 and was completed late last year, “five months early and on budget”, says nuclear physicist Bradley Sherrill, who is FRIB’s science director.

For decades, nuclear physicists had been pushing for a facility of its power — one that could produce rare isotopes orders of magnitude faster than is possible with the NSCL and similar accelerators worldwide. The first proposals for such a machine came in the late 1980s, and consensus was reached in the 1990s. “The community was adamant that we need to get a tool like this,” says Witold Nazarewicz, a theoretical nuclear physicist and FRIB’s chief scientist.

A tiny research robot is living with an Antarctica penguin colony

Posted by in category: robotics/AI

ECHO, the robot, belongs to the Woods Hole Oceanographic Institution and rolls around the tundra collecting data used to study marine ecosystems.

The small robot takes readings and collects data like a normal researcher, but his existence allows researchers to collect real-time information year round and minimize the impact their presence could have on the animals’ lives.

Researchers say the penguins seem to be getting along swimmingly with the robot.

Prostate cancer linked to bacteria, raising hope of new test and treatment

Posted by in categories: biotech/medical, innovation

A UK study has discovered five types of bacteria linked to aggressive prostate cancer. The breakthrough could help doctors identify who needs urgent treatment.


Every year, around 12,000 men in the UK die from prostate cancer, but many more die with prostate cancer than from it. So knowing whether the disease is going to advance rapidly or not is important for knowing who to treat.

Our latest study, published in European Urology Oncology, sheds some light on understanding which cancers will progress rapidly and aggressively and which won’t. Part of the answer lies with five types of bacteria.

Ah, NFT’S. I genuinely am not sure how I feel or think about them, though I DEFINITELY lean towards an annoyed 🤔MEH🙄.

What I DO know is that this is a great, brief look at the legal aspects of the issues surrounding it and the thing itself.

SpaceX smashes Falcon 9 booster turnaround record

Posted by in categories: drones, internet, satellites

SpaceX has successfully launched and landed the same Falcon 9 booster twice in three weeks, smashing the current record for orbital-class rocket turnaround.

The existing record was also held by Falcon 9 and set in early 2021 when booster B1060 launched a Turkish communications satellite and a batch of Starlink spacecraft just 27 days and 4 hours apart. Now, just under 15 months later, a new Falcon 9 booster has decisively taken the crown.

At 5:27 pm EDT, Falcon 9 B1062 lifted off as planned from SpaceX’s Cape Canaveral Space Force Station (CCSFS) Launch Complex 40 pad. Flying for the sixth time, the reused booster carried an expendable Falcon upper stage, fairing, and a batch of 53 Starlink V1.5 satellites most of the way out of Earth’s atmosphere to a velocity of 2.2 kilometers per second (Mach ~6.5) before separating and landing on a SpaceX drone ship.
