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…
Some developers say they’ve had largely positive experiences with GPT-5 so far. Jenny Wang, an engineer, investor, and creator of the personal styling agent Alta, told WIRED the model appears to be better at completing complex coding tasks in one shot than other models. She compared it to OpenAI’s o3 and 4o, which she uses…
KFF and ESPN today jointly released a first-of-its-kind, in-depth polling and reporting project that sheds new light on the health issues and other challenges facing NFL players after they leave the game. The KFF/ESPN Survey of 1988 NFL Players draws on a novel survey of 546 respondents who were among the 1,532 players from the…
