"Using an ordinary light microscope, MIT engineers have devised a technique for imaging biological samples with accuracy at the scale of 10 nanometers -- which should enable them to image viruses and potentially even single biomolecules." What they're doing is putting the sample in a hydrogel and then expanding the hydrogel. Which is done by adding water.

"Google's AI-powered reservation service Duplex is now available in 49 US states." "Google tells The Verge it has no timeline to launch the service in the last hold-out state -- Louisiana -- due to unspecified local laws. Google wowed audiences when it first unveiled Duplex at its 2018 I/O conference." I was one of the people wowed by that demo, but now I wonder, is this a service anybody actually needs?

"Amphibian eggs are microinjected with RNA. 24 hours later, the egg membrane is removed. Stem cell tissue is then harvested from the embryo. This tissue forms into a sphere. After 4 days, spheres become mobile. Individuals move by swimming. Swimming is propelled by small hairs beating on the surface. Individuals can move through diverse environments --including this maze and this narrow capillary."

V.E.R.N.AI claims to have a sentiment analysis algorithm that uses language only and is more accurate. "V.E.R.N. is a patented AI system that detects emotions in communication. It does so by analyzing the written word, or by converting audible speech to text. Our process reviews each sentence at a time, detecting latent emotional clues, or 'emotives,' that are subconsciously present in our communication."

3D printed textiles. Well, they're not quite textiles. They're "quasi-textile" flexible materials that are possible by cleverly precisely controlling the 3D printer, in particular an idea called "underextrusion". But the 3D printer and materials are just ordinary 3D printers and the same ordinary PLA plastic 3D printers use.

"National security commission led by ex-Google CEO urges US to ignore calls to ban autonomous weapons." Said ex-Google CEO is Eric Schmidt. The other person was former deputy secretary of defense Robert Work. "An official report created for President Biden and Congress has urged the US government to reject calls for a global ban on AI-powered autonomous weapons, as any commitments from Russia or China 'likely would be empty ones."

In 2016, an artificial cell was constructed from 473 bacteria genes. It was capable of reproducing and was the smallest known cell capable of reproduction. However, the cells "exhibited unusual behavior when dividing." This new research explains why, showing "we had removed genes from a naturally occurring organism that enabled it to divide like a normal cell." An accidental "mutant" made in the construction of a minimal cell revealed 19 genes.

"How I failed machine learning in medical imaging." Despite the "I" in the title, this isn't a personal story of one person's effort at medical imagine. Rather, it's an overview of problems in the medical imaging field. Those problems are categorized as: larger datasets not leading to better diagnostic accuracy, datasets only partially reflect the clinical situation for a particular medical condition, leading to dataset bias, dataset availability distorts research..."

"Go+: designed for data science. A static typed language. Fully compatible with the Go language. Script-like style, and more readable code for data science than Go." "NOTE: Go+ is still under heavy developement. Please don't use it in production environment." Seems to me like it's an interesting idea and if they can get the big ML libraries TensorFlow and PyTorch to work with it.

"The upper chamber of Wyoming's legislature has passed a bill that, if approved, would clear the way for decentralized autonomous organizations, or DAOs, to become incorporated under state law." "The 28-2 vote took place on Wednesday, public records show, and was sent to the State House of Representatives the same day. On Thursday, the bill was formally introduced and transferred to that chamber's Minerals, Business & Economic Development committee."

Remember that picture of a black hole from April, 2019? Well, now there's a new picture of the same black hole with *polarized* light. Yeah, I know, we're not technically seeing the black hole (which is black, after all), we're seeing the material falling into it. Anyway, the image with polarized light shows ripples, and they say the ripples come from magnetic field lines.

AI to generate holograms. "Holographic video displays create 3D images that people can view without feeling eye strain, unlike conventional 3D displays that produce the illusion of depth using 2D images." Basically they computer-generated 3D scenes and then made images, but the images weren't just 2D, they were 2D + depth information. They also made a 3D hologram. This was the training data for the neural network.

Gazebo is a toolbox of simulation tools for simulating robots and training robot AI systems in simulation. "Gazebo offers the ability to accurately and efficiently simulate populations of robots in complex indoor and outdoor environments. At your fingertips is a robust physics engine, high-quality graphics, and convenient programmatic and graphical interfaces. Best of all, Gazebo is free with a vibrant community."

"An expert-annotated NLP dataset for legal contract review." "Many law firms spend approximately 50% of their time reviewing contracts. Due to the specialized training necessary to understand and interpret contracts, the billing rates for lawyers at large law firms are typically around $500-$900 per hour in the US."

"Light microscopes have revolutionized our understanding of the microcosmos, but their resolution is limited to about 100 nanometers. To see how molecules bond, break, or change their structure, we need at least 1000 times better resolution." "Laser induced electron diffraction (LIED) is a technique which allows to pinpoint the individual atoms inside a single molecule, and to see where each atom moves when the molecule undergoes a reaction."

Your "smart speakers" like Amazon Alexa can now detect irregular heartbeats. Add this to the "things I never knew were possible" file. "The system sends inaudible sounds from the speaker out into a room and, based on the way the sounds are reflected back to the speaker, it can identify and monitor individual heartbeats."

"People who enjoyed reading fiction for leisure and who identified as a reader scored higher on language tests, whereas those who read to access specific information scored more poorly on the same tests." Language skills of 200 undergraduate students at York University.

The first "drone war". This video is from last November but I didn't see it until today. According to this analyst (Shekhar Gupta), the reason for Azerbaijan's decisive victory in the Azerbaijan-Armenia war of 2020 was Azerbaijan's effective use of drones (manufactured by Turkey and Israel) and Armenia's inability to defend against them.

Top 10 craziest assembly language instructions. It's actually crazy what instructions CPU makers have added to processors over the years, in their effort to squeeze every last ounce of performance out of silicon and gain a competitive advantage over other chipmakers, and this video actually has some animations of how some of them work that obviously took some real work to make.

"Deepstab: Real-time video object stabilization tool by using deep learning." "Non-feature-based stabilization + SSD + MobileNet was the best approach to achieve real-time stabilization."
