Holy mackerel! Could eating salmon, cod, tuna, herring or sardines keep our brains healthy and our thinking agile in middle age? New research makes this connection. Contact: Will Sansom, (210) 567-2579, sansom@uthscsa.edu SAN ANTONIO (Oct. 5, 2022) — Eating cold-water fish and other sources of omega-3 fatty acids may…
A blog about software craft and quality
NASA just announced the lunar landers for the Artemis program. To everyone’s surprise, SpaceX’s massive Starship is one of three landers NASA chose alongside Blue Origin and Dynetics. Understandably, this is bringing up a lot of questions. Some of which we will answer in my next video/article: “Should NASA just cancel…

Founded by polio vaccine developer Jonas Salk, the Salk Institute is an independent, nonprofit organization. We drive foundational, risk-taking research that addresses society’s most pressing challenges, including cancer, Alzheimer’s, and agricultural resilience.
[Note that this article is a transcript of the video embedded above.] In December of 2024, a huge sinkhole opened up on I-80 near Wharton, New Jersey, creating massive traffic delays as crews worked to figure out what happened and get it fixed. Since then, it happened again in February 2025 and th
An artificial intelligence model can detect people who are asymptomatic with Covid-19, through cellphone-recorded coughs. The work was led by Brian Subirana and colleagues at the MIT Auto-ID Lab.
The technology pioneered by the ETH spin-off incon.ai allows blocks to be positioned with pinpoint accuracy, creating structures with aesthetic designs and augmented acoustics.
Exploiting the quirks of human vision to make images smaller, without looking awful.
Despite tighter restrictions on antibiotics used in Canadian beekeeping, honey bee death rates are still rising. A new study led by University of Guelph researchers, published in Nature Sustainability…
A few years ago, I worked on a project to investigate the potential of machine learning to transform healthcare through modeling electronic medical records. I walked away deeply disillusioned with the whole field and I really don’t think that the field needs machine learning right now. What it does need is plenty of…
Dams serve a wide variety of purposes from hydropower to flood control to storage of water for municipal and industrials uses. But when a dam’s useful purpose fades away, the structure itself still remains. Dams come in all shapes and sizes, but contrary to what you might think, the most dangerous d

In this Weekly Chart, we look for sci-fi books and their changing titles.
I’ve been following your blog for a while and checked in today to see if there was a thread on last week’s big-splash Stanford antibody study (the one with the shocking headline that they got 50 positive results in a “random” sample of 3330 antibody tests, suggesting that nearly 2% of the population has been infected…
Rocket Lab Unveils Plans for New 8-Ton Class Reusable Rocket for Mega-Constellation Deployment
This simulation shows the heat transfer throughout various kinds of meat. In the first section, you can input the starting values for the meat. The default is a 3cm piece of steak at room temperature (73°F or 23°C). The maximum meat thickness is 30 cm since we are assuming you're not trying to cook a whole cow. The…
