Summary: Researchers have developed a new ophthalmological device that can detect degenerative visual problems such as age-related macular degeneration long before the onset of the first symptoms.

Researchers at an EPFL lab have developed an ophthalmological device that can be used to diagnose some degenerative eye disorders long before the onset of the first symptoms. In early clinical trials, the prototype was shown to produce images with a sufficient degree of precision in just five seconds.

Discovery made possible by state-of-the-art imaging and more than 60 million worms.

For the first time and in near-atomic detail, scientists at Oregon Health & Science University (OHSU) have revealed the structure of the key part of the inner ear responsible for hearing.

“This is the last sensory system in which that fundamental molecular machinery has remained unknown,” said senior author Eric Gouaux, Ph.D. He is a senior scientist with the OHSU Vollum Institute and a Howard Hughes Medical Institute investigator. “The molecular machinery that carries out this absolutely amazing process has been unresolved for decades.”

Art is a fascinating yet extremely complex discipline. Indeed, the creation of artistic images is often not only a time-consuming problem but also requires a significant amount of expertise. If this problem holds for 2D artworks, imagine extending it to dimensions beyond the image plane, such as time (in animated content) or 3D space (with sculptures or virtual environments). This introduces new constraints and challenges, which are addressed by this paper.

Previous results involving 2D stylization focus on video contents split frame by frame. The result is that the generated individual frames achieve high-quality stylization but often lead to flickering artifacts in the generated video. This is due to the lack of temporal coherence of the produced frames. Furthermore, they do not investigate the 3D environment, which would increase the complexity of the task. Other works focusing on 3D stylization suffer from geometrically inaccurate reconstructions of point cloud or triangle meshes and the lack of style details. The reason lies in the different geometrical properties of starting mesh and produced mesh, as the style is applied after a linear transformation.

The proposed method termed Artistic Radiance Fields (ARF), can transfer the artistic features from a single 2D image to a real-world 3D scene, leading to artistic novel view renderings that are faithful to the input style image (Fig. 1).

What if we could create metal made of water? Pure water itself is almost perfect as an insulator. Water found naturally in the world is a perfect conduit for electricity due to the impurities and minerals found within it. But water only becomes “metallic” at extremely high pressures. Now researchers have found a way to do so by metallicizing pure water using certain metals.

The process was first experimented with for a paper researchers published in July of 2021. Now, though, a group of researchers have managed to record the transformation of water into metal and shared the video on YouTube. The transformation is only made possible by bringing pure water into contact with electron-sharing alkali metals.

In this instance, the researchers used a combination alloy made of sodium and potassium and then added free-moving charged particles. To accomplish the transformation and create metal from water, the researchers exposed a drop of the alloy to a small amount of water vapor in a vacuum chamber. The water vapor then began to condense on the surface, expanding the droplet altogether.

Evan Spiegel, Snap CEO, “Last thing I want to do when I get home from work,” is the metaverse.

It might be big news to Mark Zuckerberg, who is all in on the metaverse, but most other big tech and social media leaders are not so hyped. In fact most of them are extremely unenthusiastic.

Speaking at the Wall Street Journal’s Tech Live conference Wednesday, several executives weighed in on what the metaverse is, with very few having kind words for the startup. While none made direct mention of the multi-billion dollar investment by meta in the virtual world, this was something that was foremost on leaders’ minds.

“You’d be crazy not to, given their track record.”

Amazon is working toward the launch of two prototype satellites for its SpaceX Starlink-rivaling internet service, Project Kuiper. The delivery giant plans to launch these first two satellites at some point next year, and earlier this year, it penned what it calls “the largest commercial procurement of launch vehicles in history.”

Amazon signed that agreement, totaling 83 Kuiper launches, with United Launch Alliance (ULA), European firm Arianespace, and Jeff Bezos’ Blue Origin.

There’s one important caveat, though.

There is a mix of excitement and fear and lots of memes.

After much back and forth and a lawsuit, four days ago, Elon Musk completed his $44 billion takeover of the social media platform Twitter. Musk had put the deal on hold after his initial offer earlier this year. Later he backed out, citing a high number of fake or spam accounts on the platform, a point that then-CEO Aggarwal had publicly denied.

Musk was then taken to court by Twitter’s lawyers. The court had given the two parties time till the month’s end to work out a deal.

As soon as Musk acquired Twitter, he proceeded to fire CEO Parag Aggarwal, finance executive Ned Segal, and legal and policy executive Vijaya Gadde.

Billionaire CEO Elon Musk has finally bought Twitter after a long saga of back-and-forth negotiations and even a lawsuit. The internet is both excited and afraid, and people are expressing their opinions in all kinds of ways.

It is the first coal carrier to be powered by hard sail wind power propulsion technology.

The world’s first partly wind-powered bulk carrier ship sailed to the Port of Newcastle on its maiden voyage this week. The Japanese shipping company Mitsui O.S.K. Lines (MOL), which delivered the 100,422 dwt (dead-weight tonnage) bulker on October 7, 2022, sailed to Newcastle on Monday, reported Offshore Energy.
