Life on Earth began from a single-celled microbe, while the rise to the multicellular world in which we live arose due a vital chemical process known as biomineralization, during which living organisms produce hardened mineralized tissue, such as skeletons. Not only did this phenomenon give rise to the plethora of body plans we see today, but it also had a major impact on the planet’s carbon cycle.

Fossil skeletons of cloudinids (Cloudina), tubular structures comprised of carbonate cones up to ~1.5cm in length, have been found in Tsau Khaeb National Park, Namibia, dating back to 551–550 million years ago in the Ediacaran (~635–538 million years ago). Dr. Fred Bowyer, from the University of Edinburgh, and colleagues aimed to use these fossils to define the location, timing and reason for why biomineralization initiated on Earth and the magnitude of its impact.

New research published in Earth and Planetary Science Letters combines sediment analysis with geochemical data in the form of carbon and (the same element with different atomic masses) from limestones in the Kliphoek Member, Nama Group. The research team suggest this rock was once deposited in a during a lowstand before a period of transition to open marine conditions.

Researchers at Tokyo Tech have demonstrated that in-cell engineering is an effective method for creating functional protein crystals with promising catalytic properties. By harnessing genetically altered bacteria as a green synthesis platform, the researchers produced hybrid solid catalysts for artificial photosynthesis.

Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.

That’s one idea for how the brain organizes itself to support our thoughts, feelings, and emotions. But if the brain’s information processing dynamics are like waves, what happens when there’s turbulence?

In fact, the brain does experience the equivalent of neural “hurricanes.” They bump into one another, and when they do, the resulting computations correlate with cognition.

These findings come from a unique study in Nature Human Behavior that bridges neuroscience and fluid dynamics to unpack the inner workings of the human mind.

According to this information covid 19 sars is a chimeric virus that evolves with other genetic material which gives us clues for a proper antidote. Also it shows why it is so dangerous.

Ben Hu denies he was sick in late 2019, or that his coronavirus work led to COVID-19, and newly declassified U.S. intelligence doesn’t substantiate allegations against him.

Best known for co-discovering the gömböc—the first convex 3D shape with just two balancing points—Domokos aims to understand the physical world by describing its forms in the simplest possible geometry.

He often begins new projects by concocting original ways to classify shapes. To prove that the gömböc existed before they found it, he and Péter Várkonyi introduced mathematically precise definitions of flatness and thinness. To categorize pebbles, Domokos counts their number of stable and unstable balancing points. And to describe tessellating patterns in rock cracks or nanomaterials, he calculates just two numbers: the average number of “tiles” meeting at each vertex in the “mosaic” and the average number of vertices per tile.

The point is to find “a new language” to describe the shapes, says mathematician Krisztina Regős, one of Domokos’s graduate students. “The first thing that people do when they understand something: give it a name,” Domokos says. “And shapes don’t have names.”

Core inflation remains elevated in advanced economies, with economists calling for tighter monetary policies in order to improve price and financial stability for sustained economic growth. With inflation only slowly moving towards sustainable targets, investors can leverage insights into teen spending patterns, behaviors, and advancements in technology to identify broader economic and market trends.

In a recent Piper Sandler Taking Stock With Teens survey that analyzed discretionary spending patterns, fashion trends, technology, and brand and media preferences, inflation was determined to be the number two social concern among teens, pointing to initial signs of a slowdown in teen spending.

“Inflation reached its highest mindshare in terms of political and social issues, right behind the environment,” said Edward Yruma, senior research analyst.

AI feature only available in the US.

Google announced Thursday that it’s adding another generative AI feature to its Search engine. Google is giving users the ability to create images using textual prompts. For now, it’s only available to users in the United States who have opted for Google’s experimental Search Generative Engine (SGE), which integrates generative AI into the world’s most visited website.

A user could type in “hands holding flowers with a view of mountains in the background,” the search engine would spew up to four images in the results. Because Google doesn’t want users to… More.

The researchers tested their algorithm on a replica of a US Army combat ground vehicle and found it was 99% effective in preventing a malicious attack.

Australian researchers have developed an artificial intelligence algorithm to detect and stop a cyberattack on a military robot in seconds.

The research was conducted by Professor Anthony Finn from the University of South Australia (UniSA) and Dr Fendy Santoso from Charles Sturt University in collaboration with the US Army Futures Command. They simulated a MitM attack on a GVT-BOT ground vehicle and trained its operating system to respond to it, according to the press release.

According to Professor Finn, an autonomous systems researcher at UniSA, the robot operating system (ROS) is prone to cyberattacks because it is highly networked. He explained that Industry 4, characterized by advancements in robotics, automation, and the Internet of Things, requires robots to work together, where sensors, actuators, and controllers communicate and share information via cloud services. He added that this makes them very vulnerable to cyberattacks. He also said that computing power is increasing exponentially every few years, enabling them to develop and implement sophisticated AI algorithms to protect systems from digital threats.

The service was supposed to be launched in beta this year but has been pushed back after Starship has failed to reach orbit.

SpaceX’s satellite-powered mobile telephony service could be available in 2024, according to recent changes in the service provider’s webpage. Direct to Cell will allow text, voice, and data services from Starlink’s V2 satellites.

Launched more than 30 years ago, satellite-based telephone services are still as challenging to use as they were back then. With the advent of satellite-based internet services, thanks to Starlink, interest in telephony has increased again. Apple introduced it in their latest iPhone but limited it to emergency purposes and nothing beyond basic texts.

A study finds a material that is 120 times faster than similar ones, demonstrating its precision in remotely stimulating neurons and repairing severed sciatic nerves in rats.

A new study is paving the way for alternative approaches to treating brain and nerve problems gently without the need for major surgery by introducing a magnetoelectric material.

Despite challenges such as nerve cells not responding well to the signals made by these materials, Researchers wanted to find a way to make these signals easier for our nerves to understand.
