A drought lasting 13 years and several others that each lasted over three years may have contributed to the collapse of the Classic Maya civilization, chemical fingerprints from a stalagmite in a Mexican cave have revealed. A detailed analysis of oxygen isotopes in the stalagmite allowed a team of researchers, led by the University of…
A proposed earthquake early warning system could have provided several communities an alert of 10 seconds or more ahead of strong shaking from the magnitude 7.3 quake that occurred south of Sand Point near the tip of the Alaska Peninsula in mid-July. That analysis is provided by Alex Fozkos of the Alaska Earthquake Center’s systems…
White sharks exhibit stark differences between the DNA in their nuclei and the DNA in their mitochondria. Until now, scientists have pointed to the migration patterns of great whites to explain these differences. Scientists tested this theory in a new study by analyzing genetic differences between global white shark populations. In doing so, they discovered…
A research team from the Institut de Ciències del Mar (ICM-CSIC) has published a study in Communications Biology showing how ocean acidification and warming — two of the main consequences of global climate change — can simultaneously affect the structure, mineral composition, and microbiome of bryozoans, colonial invertebrates crucial for forming marine habitats. The findings…
Just as overlapping ripples on a pond can amplify or cancel each other out, waves of many kinds — including light, sound and atomic vibrations — can interfere with one another. At the quantum level, this kind of interference powers high-precision sensors and could be harnessed for quantum computing. In a new study published in…
Research from scientists at University of California San Diego School of Medicine have shed new light on an age-old question: what makes the human brain unique? The team’s discovery comes from their investigation of human-accelerated regions (HARs) — sections of the human genome that have accumulated an unusually high level of mutations as humans have…

Chat-based assistants powered by Retrieval Augmented Generation (RAG) are transforming customer support, internal help desks, and enterprise search, by delivering fast, accurate answers grounded in your own data. With RAG, you can use a ready-to-deploy foundation model (FM) and enrich it with your own data, making responses relevant and context-aware without the need for fine-tuning…
This post is a joint collaboration between Salesforce and AWS and is being cross-published on both the Salesforce Engineering Blog and the AWS Machine Learning Blog. The Salesforce AI Platform Model Serving team is dedicated to developing and managing services that power large language models (LLMs) and other AI workloads within Salesforce. Their main focus…
Never mind the GPT-5 complaints; Sam Altman says he believes ChatGPT is on track to have more conversations per day than all human beings combined. “If you project our growth forward, pretty soon billions of people a day will be talking to ChatGPT,” said the CEO of OpenAI during a dinner with journalists in San…
