Chemical computer can recognise patterns and perform multiple tasks

-

 




A chemical computer made from a network of enzymes can perform a variety of tasks, like measuring temperatures or identifying substances, without needing to be rebuilt each time. This makes it more like an adaptive biological system than a digital circuit, and offers the promise of linking computers with biology.

Living organisms contain molecular networks that constantly integrate chemical and physical signals, such as when cells sense nutrients, hormones or temperature changes and adjust to stay alive. For decades, researchers have tried to mimic this in a variety of ways, such as building logic gates from DNA, but most of these artificial systems have been either too simple, too rigid or too difficult to scale.

Japan’s Innovative Approach to Artificial Intelligence Legislation

-
Image
  Japan introduced law aimed at encouraging artificial intelligence (AI) research and development. This legislation, known as the Act on the Promotion of Research, Development and Utilisation of Artificial Intelligence-Related Technologies, seeks to position Japan as a leader in the global AI landscape. The law diverges from stringent regulatory frameworks like the European Union’s AI Act, instead promoting an innovation-driven environment. Key Features of Japan’s AI Law The Act establishes an Artificial Intelligence Strategy Headquarters under the Cabinet. This body is responsible for formulating a national Basic Plan for AI. The plan encompasses foundational research, industrial deployment, international collaboration, and public education. The law avoids rigid regulatory frameworks and focuses on enabling innovation and encouraging cooperation among stakeholders. Comparison with the European Union’s AI Act In contrast to Japan’s approach, the EU’s AI Act employs a risk-based cl...

EMM-Negative Blood Group System

-
Image
  The International Society of Blood Transfusion officially recognised a new blood group system named EMM-negative, also known as Gwada negative. This designation emerged from the unique case of a woman from Guadeloupe who is the only known individual to possess this rare blood type. The discovery puts stress on advancements in transfusion medicine and genetic research. What is Gwada Negative? Gwada negative refers to the EMM-negative blood group system, identified by the absence of the EMM antigen on red blood cells. This antigen is a high-incidence antigen, present in almost all humans. The lack of such a common antigen is medically and has led to the classification of this blood type as the 48th globally recognised system in transfusion science. Discovery Process The identification of the EMM-negative blood type began in 2011 when the woman underwent routine blood tests. Initial attempts to classify her blood were inconclusive due to the lack of technology. In 2019, advancement...

Non-Binary AI Chip

  China has made leap in artificial intelligence with the deployment of non-binary AI chips. This advancement comes from Professor Li Hongge’s team at Beihang University. They have developed a novel computing approach called Hybrid Stochastic Number (HSN) computing. This innovation aims to address critical limitations in conventional computing. About Hybrid Stochastic Number Computing Hybrid Stochastic Number computing merges traditional binary logic with probabilistic logic. Binary systems operate on precise calculations using 1s and 0s, which are energy-intensive. In contrast, stochastic computing uses voltage signal frequencies to represent values, resulting in lower power consumption but often slower performance. The HSN system combines these approaches to achieve a balance of energy efficiency and computational reliability. Addressing Key Limitations in Conventional Chips Two major limitations challenge conventional chips – the power wall and the architecture wall. The power ...
