A new approach to AI’s “thinking” mimics the human brain and has the potential to revolutionize the AI industry.

Artificial Intelligence (AI) can perform complex calculations and analyze data faster than any human, but to do so requires enormous amounts of energy. The human brain is also an incredibly powerful computer, yet it consumes very little energy.

Suin Yi, assistant professor of electrical and computer engineering at Texas A&M University’s College of Engineering, is on a team of researchers that developed “Super-Turing AI,” which operates more like the human brain.

This new AI integrates certain processes instead of separating them and then migrating huge amounts of data like current systems do.

The “Turing” in the system’s name refers to AI pioneer Alan Turing, whose theoretical work during the mid-20th century has become the backbone of computing, AI, and cryptography. Today, the highest honor in computer sciences is called the Turing Award.

The findings appear in Science Advances.

 

 

3-D Printed skin to replace animal testing– www.sciencedaily.com

A research team from TU Graz and the Vellore Institute of Technology in India is developing a 3D-printed skin imitation equipped with living cells in order to test nanoparticles from cosmetics without animal testing.

Directive 2010/63/EU laid down restrictions on animal testing for the testing of cosmetics and their ingredients throughout the EU. Therefore, there is an intense search for alternatives to test the absorption and toxicity of nanoparticles from cosmetics such as sun creams. A team of researchers from Graz University of Technology (TU Graz) and the Vellore Institute of Technology (VIT) in India is working on the development of skin imitations that mimic the native three-layer tissue structure and biomechanics of human skin. Such imitations can be produced using 3D printing and consist of hydrogel formulations that are printed together with living cells.

Hydrogels in which skin cells survive and grow

“The hydrogels for our skin imitation from the 3D printer have to fulfil a number of requirements,” says Karin Stana Kleinschek from the Institute of Chemistry and Technology of Biobased Systems. “The hydrogels must be able to interact with living skin cells. These cells not only have to survive, but also have to be able to grow and multiply.” The starting point for stable and 3D-printable structures are hydrogel formulations developed at TU Graz. Hydrogels are characterised by their high-water content, which creates ideal conditions for the integration and growth of cells. However, the high-water content also requires methods for mechanical and chemical stabilisation of the 3D prints.

Trump’s tariffs will deliver a big blow to climate tech– www.technologyreview.com

The growing policy uncertainty and weakening economic conditions alone may already be causing some of this to occur.

Since Trump took office, companies have canceled, delayed, or scaled back at least nine US “clean energy supply chain” developments or operations, according to the Big Green Machine, a database maintained by Jay Turner, a professor of environmental studies at Wellesley College, and student researchers there. The projects that have been affected represent some $8 billion in public and private investments, and more than 9,000 jobs.

They include KORE Power’s planned battery facility in Arizona, which the company halted; Envision Automotive Energy Supply’s paused expansion in Florence County, South Carolina; and Akasol’s closure of two plants in Michigan.

VW also scaled back production at its recently expanded EV factory in Chattanooga, Tennessee, amid slower-than-expected growth in sales and, perhaps, the expectation that the Trump administration will strive to roll back consumer tax credits for vehicle purchases.

Ford Offers Discounts on Cars and Trucks as Auto Tariffs Kick In– www.nytimes.com

Ford Motor said on Thursday that it was lowering prices on most of its vehicles to the same levels it charges employees in a bid to boost sales as President Trump’s tariffs on imported cars took effect.

The tariffs began on Thursday on vehicles imported from Mexico, Canada, Japan, Germany and other countries. The duties — 25 percent of the value of the vehicle in most cases — are expected to increase prices of new cars and trucks and dampen demand.

About half the vehicles sold in the United States each year are produced in other countries. Mexico is the top source of those cars and Canada is among the largest. For three decades, the United States, Canada and Mexico have had a free-trade zone, and automakers have moved parts and vehicles freely among the three countries.

Ford’s new program, which the company is calling “From America, for America,” could help reduce a large inventory of unsold cars. In February, Ford had more cars in inventory as measured by how many days it would take to sell them all than all but three other brands — Jaguar, Mini and Dodge — according to Cox Automotive, a research firm.

Denmark to purchase 130 armoured personnel carriers from Patria  – www.army-technology.com

Denmark has become a participant in the Finnish-led Common Armoured Vehicle System (CAVS) initiative with the Danish government outlining plans to acquire 130 CAVS units from Patria.

The financial commitment is equivalent to roughly €250m ($270.45m). The acquisition strategy involves procuring a smaller quantity of vehicles within the current year followed by a more substantial order in the subsequent year.

The country anticipates that the integration of CAVS vehicles will bolster its national defence capabilities. Furthermore, Denmark regards the CAVS programme as an efficient mode of collaboration among Nordic nations.

Denmark Minister of Defence Troels Lund Poulsen said: “With the purchase of armoured personnel carriers from Patria, we are strengthening the Army broadly with a contribution to both the light infantry battalion and the heavy brigade, so that Denmark’s defence is modernised and the soldiers have updated equipment. At the same time, it is important to strengthen the European defence industry – and that Denmark supports the industry by buying European. We are doing that with this purchase.”

The statement provided three examples, the most prominent of which was Semiconductor Manufacturing International Corporation (SMIC), China’s largest chip maker, which is partially owned by the Chinese state. The company had started recruiting staff via a front company set up in Taiwan as a subsidiary of a separate entity apparently based in the island of Samoa, the MJIB claimed.

Meanwhile, Chinese networking chip company Cloudnix, had “aggressively recruited talent from major global firms such as Intel and Microsoft since its establishment in 2020,” the MJIB said. The company had set out to hide its Chinese control by registering itself in Taiwan, and later, to avoid deeper scrutiny, as being owned by an entity based in Singapore.

A third, Shenzhen Torey Microelectronics Technology, had tried to hire Taiwanese from inside the country while keeping its presence on the island a secret.
