A well-known game studio is allegedly using AI voices for a video game. A clarification includes a commitment to human creativity. It’s another footnote in the debate over the value of human labor that will become more common in the future.

It’s the very debate that has erupted so vehemently around AI-generated images in recent months. Are AI images art? If so, can they be equated with human art? Are they detrimental to art? Are they even plagiarism, because the AI examines human works during training – in the inspiration phase, so to speak – and then imitates them in trace elements?

Image generation machines like DALL-E 2, Stable Diffusion, and Midjourney alone raise myriad questions about the value and interplay of human and machine labor. These questions are likely to increase because generative AI will not stop at 2D images. Another area it is already tapping into is audio.

Scientists at the Krembil Brain Institute, part of the University Health Network, have proposed a new mechanistic model (AD2) for Alzheimer’s, looking at it not as a brain disease, but as a chronic autoimmune condition that attacks the brain.

This novel research is published today, in Alzheimer’s & Dementia.

“We don’t think of Alzheimer’s as fundamentally a disease of the . We think of it as a disease of the immune system within the brain,” says Dr. Donald Weaver, co-Director of the Krembil Brain Institute and author of the paper.

Methuselah Foundation recently announced a $1 million competition to.
encourage innovation that will enable medicine to move away from unreliable.
animal testing. The change is long overdue. In the U.S., all our food and.
drug research has been guided by the 1938 Federal Food, Drug and Cosmetics.
Act, which requires that every drug be tested on animals. While this was.
state-of-the-art scientific process 84 years ago, we can do much better today. The reason why is simple: Animal testing is unreliable, ineffective.

And costly.

Open source is fertile ground for transformative software, especially in cutting-edge domains like artificial intelligence (AI) and machine learning. The open source ethos and collaboration tools make it easier for teams to share code and data and build on the success of others.

This article looks at 13 open source projects that are remaking the world of AI and machine learning. Some are elaborate software packages that support new algorithms. Others are more subtly transformative. All of them are worth a look.

Every summer, weather forecasters blast news about African dust plumes crossing the southern United States. And to most people, it’s just dust, but to researchers at Texas A&M University, it’s much more.

Researchers have developed a new method called isotope-resolved chemical mass balance to identify dust participles using isotopic measurements. Their new research builds off previous studies where they identified and quantified the dust by determining the .

The study was recently published in Environmental Science & Technology.

The use of immunodetection assays including the widely used enzyme-linked immunosorbent assay (ELISA) in applications such as point-of-care detection is often limited by the need for protein immobilization and multiple binding and washing steps. Here, we describe an experimental and analytical framework for the development of simple and modular “mix-and-read” enzymatic complementation assays based on split luciferase that enable sensitive detection and quantification of analytes in solution. In this assay, two engineered protein binders targeting nonoverlapping epitopes on the target analyte were each fused to nonactive fragments of luciferase to create biosensor probes. Binding proteins to two model targets, lysozyme and Sso6904, were isolated from a combinatorial library of Sso7d mutants using yeast surface display.

Researchers have developed a metasurface device that can display three types of images depending on the illumination light. The three-channel device could be used as an anticounterfeiting measure or offer a new way to securely deliver encrypted information.

“Metasurfaces are artificial materials with tiny nanostructures that can be used to manipulate light,” said research team member Qi Dai from Wuhan University in China. “In this work, we exploited both the size and orientation of the nanostructures to design a metasurface with three working modes.”

The researchers describe the new device in Optics Express. They also showed that depending on the light used, the metasurface would generate a holographic image or a structural-color nanoprinting image with or without polarization-dependent watermarks.
