In #Argentina this afternoon, major #dust activity in the middle of a dry winter.

Sudden DECREASE IN AIR POLLUTION improves HEALTH immediately & over 3 yrs

- Emergency visits for cardiovascular disease decreased 42% immediately, continued over 3 yrs

#Sunrise over #Patagonia today, with continuous #highlatitudedust activity (posted about it last 2 days) with abundant snow farther south.

This illustrates that dust storms (or more generally, dust activity) can happen in cold weather and during the winter.

‼️Sobrevivir como investigadoras no tendría que ser un acto de equilibrio tan arriesgado y agotador. Toda la sociedad se beneficiaría si las científicas recibieran apoyo para contribuir de forma equitativa al progreso de la ciencia, desde sus formas de hacer y de pensar propias y diferentes.‼️ ✍️ Marta Bueno Saz.

Sunrise in #Patagonia today and there is a very long plume of #highlatitudedust from dry lake Colhué Huapi.

The long plume indicates that activity started during nighttime and it's been active for several hours.

In color is the Aerosol Optical Depth , a proxy of concentration that it is used to derive particle matter amount (dust mass cannot be directly measured from space)

This morning in #Patagonia, #highlatitudedust activity from several dry lakes (including the large dry bed Colhué Huapi) . Long dust plumes.

The winds are such that dust initially moves east and then veers south making likely this dust will reach the #SouthernOcean and maybe #Antarctica.

This is a good example of dust activity in the middle of the winter (there is even snow not too far south , red circle)

There's very little upside to commenting publicly on the ongoing debate about whether COVID was a lab leak or natural introduction, but I couldn't turn down a request from David Quammen, whose writing I've admired for over 30 years.

TL;DR #chatgpt is unfit for responsible use in science & education. Open instruction-tuned text generators (LLM + RLHF) are on the rise. But how open are they? We track degrees of openness in this #CUI23 paper & live at https://opening-up-chatgpt.github.io

We hope this paper & repository will help more people make mindful choices about tech

Remember that abysmal attempt at creating a fake paper detector that #Science magazine trumpeted? The one that just looked to see if you used your institutional email address, had international collaborators, and were affiliated with a hospital?

The one that instantiated the authors biases and then they turned around and used as evidence for those biases?

Science has just published the letter that Brandon Ogbunugafor and I wrote in response.

Kudos to them for that...

Todos los medios digitales se tiran a la noticia de que Meta saca Threads, y adoran la "nueva" red social, pero pasan de puntillas por la razón por la que no estará disponible en Europa: https://www.eldiario.es/tecnologia/zuckerberg-no-lanzara-espana-nuevo-twitter-reto-pelea-elon-musk_1_10353259.html.

Es más, todos se lanzan a decirte cómo puedes instalartela saltándote esa limitación.

Junté algunos números para escribir algo sobre el consumo desenfrenado de energía de los #DataCenters 🔌

Mención especial a @archipielago y agradezco a @sejo por sus comentarios en el borrador inicial

Consumo de energía de los data centers y el costo ambiental de nuestra vida digital.

La infraestructura detrás de las tecnologías digitales de comunicación consume cada vez más energía. El problema es que poco sabemos sobre el impacto ambiental que tiene la tecnología que en el imaginario colectivo es una nube sin espacio físico pero
