Methods of Lysergic Acid Synthesis—The Key Ergot Alkaloid

Posted by in category: futurism

Ergot is the spore form of the fungus Claviceps purpurea. Ergot alkaloids are indole compounds that are biosynthetically derived from L-tryptophan and represent the largest group of fungal nitrogen metabolites found in nature. The common part of ergot alkaloids is lysergic acid. This review shows the importance of lysergic acid as a representative of ergot alkaloids. The subject of ergot and its alkaloids is presented, with a particular focus on lysergic acid. All methods of total lysergic acid synthesis—through Woodward, Hendrickson, and Szantay intermediates and Heck coupling methods—are presented. The topic of biosynthesis is also discussed.

Biotech is the new focus in U.S.-China tech rivalry

Posted by in categories: biotech/medical, economics, food, security

The need to quash outbreaks, quickly create medicines, stress-proof crops and fend off other 21st century threats is providing a lucrative arena for biotech companies to sell their services.

Why it matters: But the infrastructure to support such ambitions is increasingly recognized by the U.S., China and other countries as a linchpin of national security and economic strategy, putting it at the center of geopolitics.

Team develops a laser printer for photonic chips

Posted by in categories: biotech/medical, health, internet, quantum physics, robotics/AI

Photonic integrated circuits are an important next-wave technology. These sophisticated microchips hold the potential to substantially decrease costs and increase speed and efficiency for electronic devices across a wide range of application areas, including automotive technology, communications, health care, data storage, and computing for artificial intelligence.

Photonic circuits use photons, fundamental particles of light, to move, store, and access information in much the same way that conventional electronic circuits use electrons for this purpose. Photonic chips are already in use today in advanced fiber-optic communication systems, and they are being developed for implementation in a broad spectrum of near-future technologies, including light detection and ranging, or LiDAR, for autonomous vehicles; light-based sensors for medical devices; 5G and 6G communication networks; and optical and quantum computing.

Given the broad range of existing and future uses for photonic integrated circuits, access to equipment that can fabricate chip designs for study, research and industrial applications is also important. However, today’s nanofabrication facilities cost millions of dollars to construct and are well beyond the reach of many colleges, universities, and research labs.

‘Landmark event’: Chinese scientists assemble world’s most detailed human genome

Posted by in category: biotech/medical

The lack of representation of Asians in the genome can cause “large deviations” when diagnosing or treating patients, and could affect the development of targeted drugs, he said.

To address the gap, in 2020 Gao and his research team set out to construct a reference of the Chinese genome, particularly of the Han ethnicity, the largest ethnic group in the world.

AI learns language through the experience of a single child in groundbreaking study

Posted by in category: robotics/AI

In a groundbreaking study published in the journal Science, researchers have developed a machine learning model that mimics the way children learn language, offering new insights into early language acquisition. Using video and audio recordings from a young child’s perspective, the model successfully learned to associate words with visual objects, a feat that sheds light on the mysterious process of how children begin to understand and use language.

Understanding how children learn language has long been a fascinating subject for scientists and educators alike. At the heart of this is the phenomenon of connecting words to their meanings – a process seemingly simple yet incredibly complex. This study sought to demystify this process using the latest advancements in artificial intelligence.

The motivation behind this research lies in the need for a deeper understanding of early language acquisition. Traditionally, studies in this field have been conducted in controlled laboratory settings, which may not accurately reflect the natural environment in which children learn language.
