Inventions for battery reuse and recycling increase seven-fold in last decade
As global battery demand continues to surge, the number of end-of-life batteries from electric vehicles alone is expected to grow from 1.2 million in 2030 to 14 million by 2040. Battery circularity technologies enable the reuse and recycling of these batteries and, as with battery technologies more generally, Asia…

Living skin can be 3D-printed, with blood vessels
TROY, N.Y. — Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies produce naturally.

Prefrontal cortex as a meta-reinforcement learning system
Recently, AI systems have mastered a range of video-games such as Atari classics Breakout and Pong. But as impressive as this performance is, AI still relies on the equivalent of thousands of hours of gameplay to reach and surpass the performance of human video game players. In contrast, we can usually grasp the…

GLP-1 drugs linked to lower death rates in colon cancer patients
In an analysis of more than 6,800 colon cancer patients across all University of California Health sites, researchers found that those taking glucagon-like peptide-1 (GLP-1) medications were less than half as likely to die within five years compared to those who weren’t on the drugs (15.5% vs. 37.1%

A nasal spray protects against coronavirus including immune-evasive variants
Researchers have developed a molecule that is, when administered nasally, extremely effective in preventing the disease caused by all known variants of the SARS-CoV-2 virus. The molecule can be a key tool in preparing for future pandemics, as it is aimed at preventing both the transmission and spread of the virus.

AlphaFold 2 is here: what’s behind the structure prediction miracle
Nature has now released that AlphaFold 2 paper , after eight long months of waiting. The main text reports more or less what we have known for nearly a year, with some added tidbits, although it is accompanied by a painstaking description of the architecture in the supplementary information . Perhaps more importantly…

Team from ETH Zurich make high quality quantum swap gate using a geometric phase
Researchers at ETH Zurich have realised particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases they are extremely robust against experimental noise and can be used in quantum computers in the future.
