Chemistry and AI pushes biosignature detection for life back billions of years - Share this on Facebook Share this on X (Twitter) Share this on LinkedIn Share this on Bluesky Share this on Reddit Share this on WhatsApp Share this by email More share options Ancient microfossils and isotopic signatures of carbon point to the earliest life on Earth forming around 3.45 billion years ago. Conversely, there is scant biochemical evidence of life preserved in ancient rock that has survived billions of years of geological processes. The earliest unambiguous records of complex biomolecules such as lipids and porphyrins " involved in compartmentalising early chemistry and metabolic pathways, respectively " stem from around 1.7 billion years ago, leaving a huge gap in the biochemical record…...

11+ hour, 13+ min ago (322+ words) Credit: Macrovector / Getty Images Artificial intelligence systems that are designed with a biologically inspired architecture can simulate human brain activity before ever being trained on any data, according to new research from Johns Hopkins University. The findings, published in Nature Machine Intelligence, challenge conventional approaches to building AI by prioritizing architectural design over the type of deep learning and training that takes months, costs billions of dollars and requires thousands of megawatts of energy. Bonner and a team of scientists focused on three classes of network designs that AI developers commonly use as blueprints for building their AI systems: transformers, fully connected networks, and convolutional networks. The scientists repeatedly modified the three blueprints, or the AI architectures, to build dozens of unique artificial neural networks. Then, they exposed these new and untrained AI networks to images of objects, people, and…...

3+ day, 10+ hour ago (149+ words) Georgia Tech and NASA used advanced chromatography and a new computational tool to compare organic compounds in meteorite and terrestrial rock samples. "Determining whether organic molecules in planetary samples originate from biological or nonbiological processes," the authors wrote in their article, "is central to the search for life beyond Earth. Yet, distinguishing these origins is challenging due to overlapping chemical signatures and limited access to pristine extraterrestrial materials." (1) "In contrast to traditional biomarker-based approaches," the authors wrote, "LifeTracer analyzes untargeted chemical signatures to infer molecular origin with high accuracy. It enables scalable, unbiased biosignature detection and offers a powerful tool for interpreting complex organic mixtures returned by current and future planetary missions" (1).

3+ day, 12+ hour ago (319+ words) AWS has launched Flexible Training Plans (FTPs) for inference endpoints in Amazon SageMaker AI, its AI and machine learning service, to offer customers guaranteed GPU capacity for planned evaluations and production peaks. Typically, enterprises use SageMaker AI inference endpoints, which are managed systems, to deploy trained machine learning models in the cloud and run predictions at scale on new data. For instance, a global retail enterprise can use SageMaker inference endpoints to power its personalized-recommendation engine: As millions of customers browse products across different regions, the endpoints automatically scale compute and storage to handle traffic spikes without the company needing to manage servers or capacity planning. According to AWS, FTPs for inferencing workloads aim to address this by enabling enterprises to reserve instance types and required GPUs, since automatic scaling up doesn't guarantee instant GPU availability due to high demand…...
