The serotonin theory of depression: a systematic review of the evidence (2022)
Abstract The serotonin hypothesis of depression is still influential. We aimed to synthesise and evaluate evidence on whether depression is associated with lowered serotonin concentration or activity in a systematic umbrella review of the principal relevant areas of research. PubMed, EMBASE and PsycINFO were searched using terms appropriate to each area of research, from their […]
Man’s brain turned to glass by hot Vesuvius ash cloud
4 days ago ShareSave Georgina Rannard Climate and science reporter ShareSave Guido Giordano Nearly 2,000 years after a young man died in the Vesuvius volcanic eruption, scientists have discovered that his brain was preserved when it turned to glass in an extremely hot cloud of ash. Researchers found the glass in 2020 and speculated that […]
Launch HN: Bild AI (YC W25) – Understands Construction Blueprints Using AI
Hi HN! We’re Roop and Puneet, the founders of Bild AI (https://www.bild.ai). Bild AI uses machine learning to read construction blueprints and extract detailed material quantity and cost estimates. Here’s our demo: https://youtu.be/vBDl7Mh7iEc The problem we’re tackling is the sheer manual effort that goes into generating material quantities and cost estimates from blueprints today. Contractors […]
Goodbye K-9 Mail
TL;DR: I quit my job working on Thunderbird for Android and K-9 Mail at MZLA. My personal journey with K-9 Mail started in late 2009, shortly after getting my first Android device. The pre-installed Email app didn’t work very well with my email provider. When looking for alternatives, I discovered K-9 Mail. It had many […]
How to run GUI applications directly in containers
This tutorial introduces a method for running GUI applications directly in containers (such as Docker and Podman) without installing any additional software. When would you need to run GUI applications inside containers? The source of the GUI application is untrusted, or its safety is uncertain. You want to try a GUI application without installing it […]

Harvest the sun twice: Agrivoltaics promises sustainable food, energy and water
Combining solar power production with agriculture can significantly boost crop yields, conserve water and generate low-carbon electricity for areas particularly vulnerable to climate change, a new study has shown. A new international study, led by the University of Sheffield, found using the same land for both solar energy production and agriculture can generate low-carbon electricity, […]
The three-dimensional Kakeya conjecture, after Wang and Zahl
The three-dimensional Kakeya conjecture, after Wang and Zahl 25 February, 2025 in expository, math.CA, math.MG | Tags: Hong Wang, induction on scales, Joshua Zahl, Kakeya conjecture | by Terence Tao There has been some spectacular progress in geometric measure theory: Hong Wang and Joshua Zahl have just released a preprint that resolves the three-dimensional case of […]
The muon’s magnetic moment exposes a hole in the SM – unless it doesn’t
In 2021 the Muon g-2 Experiment at Fermilab found a significant discrepancy between the theoretical prediction and the experimental measurement of the anomalous magnetic moment of the muon, indicating the existence of new physics. More recently, however, an alternative prediction has found the Fermilab result to be consistent with the Standard Model. Alex Keshavarzi investigates […]
Distributed Systems Programming Has Stalled
Obligatory LLM SectionWhat can we take from these systems? Over the last decade, we’ve seen great advancements in distributed systems, but the way we program them has seen few fundamental improvements. While we can sometimes abstract away distribution (Spark, Redis, etc.), developers still struggle with challenges like concurrency, fault tolerance, and versioning. There are lots […]
