"Examinations of London schoolchildren before and after the introduction of the city’s ultra-low emission zone (Ulez) found a restoration of lung capacity that had been stunted by exposure to pollution."

Most Spanish words come from Latin, but did you know there are 2 different types? Words inherited from spoken Latin vs. words borrowed from written Latin during the Middle Ages and after. Some words took both routes, creating doublets. Here’s episode 3 of my 10-part doublet series. Next: Italian.
So it turns out... the US air travel system was incredibly, deeply dependent on federal funding to just run day-to-day all this time, to the benefit of private airline shareholders, when everyone thinks that state-run trains are leeching off the government. Weird!
We’re further away from The Rolling Stones recording “Sympathy for the Devil” than they were from the murders of the Romanovs when they recorded it
A step towards real-world applications of quantum computers! blog.google/technology/r... It was really fun to be involved in this work, by using Alpha Evolve to optimize quantum circuits.
Our Quantum Echoes algorithm is a big step toward real-world applications for quantum computing
Our latest quantum breakthrough, Quantum Echoes, offers a path toward unprecedented scientific discoveries and analysis.

¡Mapa de la renta de padre e hijos! 💶 Publicamos unos datos fascinantes. El cruce de 1) la renta de hogares de los ochenta y 2) las rentas de sus hijos hoy. En el mapa, renta bruta actual de los hijos (1980-1986) de hogares *renta baja* de cada lugar. Luego hilo👇
El gasto público sanitario por persona en Estados Unidos es 5 veces superior al de España a pesar de tener una cobertura ridícula en comparación con España Esto sucede cuando se construye sobre un sistema sanitario privado que prima los beneficios económicos por encima de la salud de los ciudadanos
Los datos que señalan que vamos a una economía de herederos como la de principios del siglo XX👇 El peso de las herencias de viviendas y del resto de inmuebles (fincas rústicas, solares...) en el PIB de España alcanza máximos no vistos desde la Primera Guerra Mundial: más del 3% eldiario.es/1_b94e3b
Whenever you hear someone sneer about scientific research that seems useless to them — “they’re studying the spit of lizards?!” — remind them that’s exactly how we got Ozempic. globalnews.ca/news/9793403...
How a Canadian scientist and a venomous lizard helped pave the way for Ozempic - National | Globalnews.ca
In 1984, Dr. Daniel Drucker, an endocrinologist from the University of Toronto, discovered a hormone that helped pave the way for popular diabetes drugs such as Ozempic.

“The demise of just one Gen1 Starlink satellite produces about 30 kilograms (66 pounds) of aluminum oxide, a compound that eats away at the ozone layer. A new study finds these oxides have increased 8-fold between 2016 and 2022, and the recent surge is increasing the pollution even more.”
Spain's boom is a story of: - energy abundance (wind, solar, LNG) - public investment thanks to NextGenEU & domestic fiscal choices - labour reforms driving higher-quality employment - immigration combined with successful integration So some luck - but also good policy.
- This massive asteroid has 99.5% chance of hitting Earth in 10 years - Should we keep it secret? People might panic - Like they are panicking for climate change, you mean? - Ah, good point.
Nunca dejará de sorprenderme la naturalidad con la que hemos aceptado que nuestra ciudad sea un gran y feo parking de coches sin espacio para nadie.

Feliz día de despistarse, de olvidar que aún hay un Imperio Romano y de crear otro.
En una provincia en la que el coche de Google maps, que pasa cada 15 años, te puede fotografiar metiendo un cadáver en el maletero en una calle desierta de un pueblo casi vacío, es esperable que la gente tenga una percepción particular de las leyes de la probabilidad y la estadística.
Error-corrected qubits are cool, and they get even more interesting when you do logic with them! Happy to present our (Google Quantum AI + @deepmind.google.web.brid.gy ) new work demonstrating scaling and logic with the color code. Arxiv: arxiv.org/abs/2412.14256
Scaling and logic in the color code on a superconducting quantum processor
Quantum error correction is essential for bridging the gap between the error rates of physical devices and the extremely low logical error rates required for quantum algorithms. Recent error-correctio...

El proyecto de ayer fue instalar LineageOS (lineageos.org) en un móvil viejo. Tuve que instalar una máquina virtual de windows para desbloquear el móvil (nadie usa windows en casa), y mi pobre ordenador se pasó una noche entera compilando, pero ha merecido la pena.
