ATCHISON, Kan. (WDAF) — It’s one of the greatest unsolved mysteries ever, but we might now be on the verge of discovering what happened to Amelia Earhart’s plane.
Earhart was born and raised in Atchison, Kansas, and her love for planes and flying drove her to break barriers for female pilots.
On June 1, 1937, she and navigator Fred Noonan made an attempt to fly around the world in a Lockheed Electra 10-E plane, but somewhere over the Pacific, they lost radio contact and were never heard from again.
Computer security company CrowdStrike is linked to a major IT outage affecting banks, airports, supermarkets and businesses across Australia and the world.
Airport check-in systems across the globe have been disrupted and businesses have reported the “blue screen of death” and IT outages.

How do you teach ChatGPT common sense? Train it on questions that adults would never think to ask. In this week’s “The Joy of Why,” computer scientist Yejin Choi talks with co-host Steven Strogatz about how training AI can mimic the “why-this, why-that” curiosity of a toddler.

The California High-Speed Rail Authority just received environmental approval to connect downtown Los Angeles to the Bay Area with a bullet train capable of reaching speeds of up to 200 miles per hour, KTLA5 reported.
KTLA5 called the approval “a historic milestone in a state notorious for holding up construction projects for environmental review.”
The California High-Speed Rail system is an ambitious project that has technically been in the works for decades, but it has progressed in fits and starts. Recently, however, construction began on several parts of the system. The initial segment, connecting Merced to Bakersfield in the Central Valley, could be open as soon as 2030, with much more to follow, KTLA5 reports.
Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Chemnitz, TU Dresden and Forschungszentrum Jülich have been the first to demonstrate that not just individual bits, but entire bit sequences can be stored in cylindrical domains: tiny, cylindrical areas measuring just around 100 nanometers.
A robotic truck equipped with a 105-ft (32-m) telescopic boom arm has just journeyed from Australia to Florida. Now the construction robot will get busy churning out up to 10 houses in a bid to become the employee of choice for building entire communities.
The truck and its accompanying brick-laying arm is known as the Hadrian X and has been developed by robotics company FBR, which first announced its prototype in 2015. That machine could complete a full-sized house in two days. Last year, FBR (which used to stand for Fastbrick Robotics), showed off the new Hadrian X which, at top speed, could stack 500 USA-format masonry blocks per hour.
The robotic vehicle/construction arm gets to work after it is loaded by pallets containing the blocks. Each block is then sent down a chute on the arm, painted with a quick-dry construction adhesive that takes the place of mortar, and is placed by a variable gripper at the end of the arm. Thanks to its impressive length, the arm is able to build structures that are three stories tall. Plus, because it’s a robot, it never needs to sleep or take a break if the weather turns nasty, so it can chug along pretty much 24/7.
Researchers have created a new class of materials called “glassy gels” that are very hard and difficult to break despite containing more than 50% liquid. Coupled with the fact that glassy gels are simple to produce, the material holds promise for a variety of applications.
Gels and glassy polymers are classes of materials that have historically been viewed as distinct from one another. Glassy polymers are hard, stiff and often brittle. They’re used to make things like water bottles or airplane windows. Gels – such as contact lenses – contain liquid and are soft and stretchy.
“We’ve created a class of materials that we’ve termed glassy gels, which are as hard as glassy polymers, but – if you apply enough force – can stretch up to five times their original length, rather than breaking,” says Michael Dickey, corresponding author of a paper on the work and the Camille and Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University. “What’s more, once the material has been stretched, you can get it to return to its original shape by applying heat. In addition, the surface of the glassy gels is highly adhesive, which is unusual for hard materials.”

The nuclear magnetic resonance in bismuth metal powder has been observed from 9 to 19 Mc/sec at 4.2\ifmmode^\circ\else\textdegree\fi{}K. The isotropic and anisotropic Knight shifts and the quadrupole coupling constant have been determined as (−1.25\ifmmode\pm\else\textpm\fi{}.30)%, (−0.3\ifmmode\pm\else\textpm\fi{}0.3)%, and 2.10\ifmmode\pm\else\textpm\fi{}.05 Mc/sec, respectively. The intrinsic linewidth was found to be 130\ifmmode\pm\else\textpm\fi{}20 kc/sec. A technique is developed to take into consideration the broadening of the observed lines due to the combined effects of the magnetic dipolar broadening and the width due to the quadrupolar splitting of each line.
A Cincinnati-based aerospace company has successfully represented a new, cutting-edge hypersonic dual-mode ramjet. The engine could enable high-speed flight and longer range across numerous multi-mission aircraft.
GE Aerospace took 11 months to develop the ramjet, which could increase in airflow compared to previously flight-tested hypersonic technology demonstrators.
“The rapid progression from design to testing underscores our commitment to driving innovation in hypersonic technologies,” said Amy Gowder, president and CEO of Defense & Systems at GE Aerospace.
