Focaccia, with its flaky crust and rich olive oil flavor, is a beloved staple—but just how far back does the delicious bread’s history stretch?

While experts know it was made in ancient Rome, new research suggests that its origins may be even older: According to a recent study in the journal Scientific Reports, Neolithic communities were making their own focaccia-like bread between 7,000 and 5,000 B.C.E.

“Studying past dietary behaviors can provide valuable information about the social and cultural aspects of ancient populations,” first author Sergio Taranto, an archaeologist at UAB Barcelona, tells ZME Science’s Rupendra Brahambhatt. “This is particularly useful for studying prehistoric communities about which we have limited knowledge due to the lack of written records.”

Universal transformer memory optimizes prompts using neural attention memory models (NAMMs), simple neural networks that decide whether to “remember” or “forget” each given token stored in the LLM’s memory.

“This new capability allows Transformers to discard unhelpful or redundant details, and focus on the most critical information, something we find to be crucial for tasks requiring long-context reasoning,” the researchers write.

NAMMs are trained separately from the LLM and are combined with the pre-trained model at inference time, which makes them flexible and easy to deploy. However, they need access to the inner activations of the model, which means they can only be applied to open-source models.

Imagine your lungs, those essential organs responsible for getting oxygen into your blood, suddenly tasked with a new job: making blood itself. It sounds almost unbelievable, right? For centuries, we’ve been taught that bone marrow is the powerhouse of blood production. Yet, a groundbreaking discovery has just turned that conventional wisdom upside down.

Benonisdottir et al. review the genetics of reproductive traits and examine how these associate with links to health, behavior, aging and longevity as well as outcomes for offspring.

In a recent study, more than 90% of participants whose stomachs had been surgically removed to prevent cancer experienced a least one chronic complication 2 years out from their surgery. For some, the complications are life-altering.

Findings from a recent study will help clinicians counsel people who are considering preventive gastrectomy about the long-term impacts of the surgery.

Chinese automaker GAC unveils its third-gen self-developed humanoid robot, showcasing motion control, navigation, and AI capabilities.

Students learning quantum mechanics are taught the Schrodinger equation and how to solve it to obtain a wave function. But a crucial step is skipped because it has puzzled scientists since the earliest days—how does the real, classical world emerge from, often, a large number of solutions for the wave functions?

Each of these wave functions has its individual shape and associated energy level, but how does the wave function “collapse” into what we see as the classical world—atoms, cats and the pool noodles floating in the tepid swimming pool of a seedy hotel in Las Vegas hosting a convention of hungover businessmen trying to sell the world a better mousetrap?

At a high level, this is handled by the “Born rule”—the postulate that the probability density for finding an object at a particular location is proportional to the square of the wave function at that position.
