Atoms viewed at highest ever resolution

Posted by in categories: information science, particle physics

Transmission electron microscopy (TEM) is a technique that involves beaming electrons through a specimen to form an image. This enables the generation of significantly higher resolution than traditional optical microscopes. While the latter devices are typically limited to around 1000x magnification due to the resolving power of visible light, TEM can provide zoom capabilities that are orders of magnitude greater – surpassing even a scanning electron microscope (SEM).

In recent years, TEM instruments have begun to reach extraordinary levels of detail. Spatial resolutions are now edging into the realm of individual atoms, measuring less than 0.0000005 millimetres (mm).

However, TEM is prone to lens aberrations and multiple scattering, limiting its use to samples thin enough to let electrons pass through. The process is technically challenging and requires additional tools to perform. In 2018, researchers at Cornell University offered a potential solution. They built a high-powered detector combined with a new algorithm-driven process called ptychography. This achieved a new record for microscopic resolution, tripling the previous state-of-the-art.

This New 8-Seat Electric Airplane Costs 80% Less to Fly Than Conventional Aircraft

Posted by in categories: sustainability, transportation

Bye Aerospace’s eFlyer 800 is a clean-sheet design that will carry eight people, including one or two pilots. The 800 will have two motors, powered by a grid of electric cells across the airframe.

This is the third model in a lineup of electric planes from the Denver-based aerospace firm, but the first with two motors. The eFlyer 2 is a two-seater for professional flight training that was developed when the company launched in 2014, and the eFlyer 4, a four-seater for air taxi and advanced training, came later. Both models have more than 360 orders each.

CAPTCHAs are annoying, but this Doom-themed one is actually fun

Posted by in category: robotics/AI

CAPTCHAs are those little tests of skill that websites use to make sure you’re human and not a bot. Sometimes they ask you to re-enter some blurry text displayed on screen, other times they show you nine images and want you to click on the images that include, say, a boat. There are a bunch of different varieties of CAPTCHA out there, but they all share at least one characteristic: they suck. But what if we lived in a world where CAPTCHAs didn’t suck? Developer Miquel Camps Orteza is presumably the only developer to ask themselves that question, and through doing so, has created an imp-shooting CAPTCHA that actually feels fun to solve. It’s called DOOM CAPTCHA, and it involves shooting three Doom imps within a short (almost too short) period of time. Weirdly, the imp exists in the Wolfenstein universe, but that inconsistency doesn’t matter because no matter where they are, shooting imps is fun.


Shoot imps to prove you’re human.

Russia is building an army of robot weapons, and China’s AI tech is helping

Posted by in categories: futurism, robotics/AI

An american source on this. Russia is way ahead of the USA on these, they were testing these in Syria, and there is no “WE CANT ARM ROBOTS!!” debate over there, they just go ahead and do it.


“In the context of increasing tensions with the United States, China and Russia have clearly made an agreement to expand their technological cooperation, with artificial intelligence playing a key role in their plans for the future,” a new CNA report finds.

Scientists recognize intruders in noise

## MATHEMATICS • MAY 24, 2021

# *Noise is commonly discarded, but identifying patterns in noise can be very useful.*

*Generalize the Hearst exponent by adding more coefficients in order to get a more complete description of the changing data. This makes it possible to find patterns in the data that are usually considered noise and were previously impossible to analyze.*
