Artificial hibernation reveals synaptic engram architecture associated with memory retention

If individual synapses were the sole key to holding onto memories, this sudden structural “demolition” should have erased everything the mice learned. Remarkably, it didn’t. Once the mice woke up and recovered, their memories were completely intact.

The Power Clusters: The synapses connecting “memory-encoding” neurons (the specific cells storing the memory) weren’t randomly scattered. Instead, they were organized into tightly bound, spatially clustered groups. When hibernation wiped out standard synapses, the brain prioritized protecting these specialized clusters.

Theoretical framework expands directional light control beyond ordered crystal structures

A research team has developed a new theoretical framework that can suppress light scattering in certain directions while enhancing it in others, even in irregularly arranged materials. The work extends research on controlling light scattering, which has traditionally centered on ordered crystal structures, into the realm of disordered systems.

Scattering—the process by which light is dispersed in multiple directions when it encounters matter—plays a critical role in determining the performance of a wide range of optical technologies, including anti-reflective coatings for eyeglasses and camera lenses, display diffusers, LiDAR sensors for autonomous vehicles, and optical communication components. Ultimately, the ability to precisely control scattering is a key determinant of competitiveness in optical technologies.

The researchers, led by Professors Sunkyu Yu and Namkyoo Park of the Department of Electrical and Computer Engineering at Seoul National University College of Engineering, in collaboration with Professor Xianji Piao of the University of Seoul, proposed a theory they call “Non-Hermitian Statistical Crystallography,” which considers not only refractive properties but also absorption and amplification.

Anthropic Reportedly in Talks to Acquire Peer Decart for $6 Billion, Bolstering Compute Ahead of IPO

AI startup Anthropic is reportedly in talks to acquire peer Decart AI for approximately $6 billion (about NT$190 billion). If finalized, the deal would mark the largest acquisition in Anthropic’s history, coming at a time when the company is preparing for its highly anticipated IPO. Bloomberg first reported the deal on August 13, noting that the agreement has not yet been finalized and negotiations could still fall through.

Anthropic has been moving at a rapid pace on both fundraising and listing preparations this year. In February, it completed a $30 billion Series G round at a post-money valuation of $380 billion. Less than three months later, in May, it closed a $65 billion Series H round, pushing its post-money valuation to $965 billion — nearly $1 trillion. In early June, Anthropic confidentially filed its S-1 registration statement with the U.S. Securities and Exchange Commission (SEC), paving the way for a future public listing. If this acquisition goes through, it would occur during a period when the company’s valuation and IPO preparations are both accelerating simultaneously.

Market sources indicate that Anthropic, which has historically made very few large acquisitions, has been investing heavily in compute capacity to develop new products and serve customers. According to sources, Decart’s software enables chips to operate more efficiently, thereby reducing the cost of training AI models. This technology would help Anthropic’s existing infrastructure handle greater demand. Upon completion of the deal, Decart’s team would join Anthropic’s inference and performance division. According to Forbes, FierceBiotech, and other media tallies, Anthropic has completed at least four acquisitions this year, including compiler startup Stainless and biotech startup Coefficient Bio (in a roughly $400 million stock deal), but all were far smaller than the Decart transaction — $6 billion would be more than ten times the size of any previously known deal.

AI is making daily life more expensive, at least for now. Here’s why

The AI boom is proving complicated for everyday Americans. It’s raising the cost of living and stopping the Fed from lowering interest rates. It is making some things faster and easier, but it is also changing how we live.

If other inflation drivers, such as tariffs and the Iran war, don’t drive prices higher from here, many economists think the inflation picture could brighten.

“Inflation remains uncomfortably high, but it’s moving in the right direction,” says Mark Zandi, chief economist of Moody’s Analytics.
