Researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences, along with collaborators from leading international institutions, have introduced an innovative cathode homogenization strategy for all-solid-state lithium batteries (ASLBs).

This new approach, detailed in their recent publication in Nature Energy on July 31, significantly improves the life cycle and energy density of ASLBs, representing an important advancement in energy storage technology.

Current ASLBs face challenges due to heterogeneous composite cathodes, which require electrochemically inactive additives to enhance conduction. These additives, while necessary, reduce the batteries’ energy density and cycle life due to their incompatibility with the layered oxide cathodes, which undergo substantial volume changes during operation.

Adopting the right mix of sustainable construction practices could allow Canada to meet its housing goals—as many as 5.8 million new homes by 2030—without blowing past its climate commitments.

Researchers in the University of Toronto’s Centre for the Sustainable Built Environment (CSBE) have developed a computer simulation that forecasts the emissions associated with new housing and infrastructure construction. The paper is published in the journal Environmental Science & Technology.

The work builds on previous CSBE research showing that in order for Canada to meet its greenhouse gas emissions targets, homes built in 2030 will need to produce 83% fewer greenhouse gases during construction than those built in 2018.

Adam D’Angelo, a board member at Microsoft (MSFT) backed OpenAI, said that general artificial intelligence is likely to occur within five to 15 years. Read for more.

ARC Prize offers US $1 million to spur artificial general intelligence research.

We asked a professional comedian to deliver some jokes written by artificial intelligence on stage. What happened reveals a lot about just how much machines understand the very human sense of humour.

Karen Hobbs was more nervous than usual before this particular gig. A well-known circuit comedian, she’s accustomed to the UK’s often bruising stand-up comedy scene. It’s eclectic, unpredictable and famously short on pity-laughs. Hobbs has tackled some of the most unforgiving rooms in Britain, from major London theatres to the back rooms of rural pubs. She has even triumphed within the dreaded competition circuit, in which a merciless audience votes in a gladiatorial popularity contest for the funniest gags.

But this Thursday night in late June, above the Covent Garden Social Club bar in Central London, Hobbs was about to attempt something totally new. She would take to the stage equipped not with her usual material, but with a stand-up set written for her by the AI platform ChatGPT. Most daunting of all, she would follow three comedians doing their actual, human material.

In 1911, Heike Kamerlingh Onnes discovered the first superconductor, metallic mercury when cooled to a critical temperature of 4.2 Kelvin, where it conducts electricity without resistance. Ever since materials scientists have been on a quest to better understand the phenomenon and whether other elements and materials have higher critical temperatures that could make them useful for practical electricity transport, with the holy grail being ambient temperature.

A new optical phenomenon has been demonstrated by an international team of scientists led by physicists at the University of Bath, with significant potential impact on pharmaceutical science, security, forensics, environmental science, art conservation and medicine.
