Scientist.
Here to share facts, and not to influence or be influenced by opinions.
I like to keep one species and its junks out of my photo frames, except for scale or as background. My approach is more realistic than artistic.

I have really enjoyed genomics.social in the ~3.5 years I've been here.

Thank you for hosting all this time @Psy_Fer_ !

Canvas Breach Disrupts Schools & Colleges Nationwide – Krebs on Security

I have a really nice (horrifying) image stack that one of my research team members made, that powerfully demonstrates what a huge problem satellite streaks are for wide-field imaging. This is a 3 hour stack of star-subtracted 5 minute exposures using the Canada-France-Hawaii Telescope. The short diagonal lines are asteroids. The long diagonal lines are sunlit satellites that passed through the field of view during the exposure.

Would you like to be part of citizen science astronomy? We invite you to classify gravitational lens candidates in so-far unreleased #ESAEuclid data: "Space Warps – ESA Euclid DR1".

3000 volunteers have already made nearly 900,000 classifications, yet 70% of the project are still to be done.

MIT's Technology Review takes a comprehensive dive into the energy/climate consequences of AI, and the news is terrible for everyone but the corporate bosses and billionaires in charge of it all. Grim, grim stuff here:

https://www.technologyreview.com/2025/05/20/1116327/ai-energy-usage-climate-footprint-big-tech/

We did the math on AI’s energy footprint. Here’s the story you haven’t heard.

The emissions from individual AI text, image, and video queries seem small—until you add up what the industry isn’t tracking and consider where it’s heading next.

New breach: ADT suffered a "pay or leak" extortion that resulted in 5.5M unique email addresses being published today. Data also included name, address, phone and a small number of DoBs and partial SSNs. 71% were already in @haveibeenpwned. Read more: https://haveibeenpwned.com/Breach/ADT
Have I Been Pwned: ADT Data Breach

In April 2026, home security firm ADT confirmed a data breach by ShinyHunters, which listed the company on its website as part of a "pay or leak" extortion attempt. The breach impacted 5.5M unique email addresses along with names, phone numbers and physical addresses. ADT also advised that "in a small percentage of cases, dates of birth and the last four digits of Social Security numbers or Tax IDs were included" and that it had contacted all affected people.

New breach: Cruise operator Carnival was targeted in a ShinyHunters “pay or leak” attack last week. 8.7M records with 7.5M email addresses and loyalty program data were published yesterday. 85% were already in @haveibeenpwned. Read more: https://haveibeenpwned.com/Breach/Carnival
Have I Been Pwned: Carnival Data Breach

In April 2026, the notorious hacking collective ShinyHunters claimed they had obtained a substantial volume of data belonging to the Carnival cruise operator and attempted to extort the organisation to prevent the data from being leaked. The following week, the group published the data publicly, which contained 8.7M records with 7.5M unique email addresses. The data contained fields indicating it related to the Mariner Society loyalty program run by Holland America, a cruise line brand under Carnival, and included names, dates of birth, genders and data relating to status within the loyalty program. Carnival acknowledged a phishing incident involving a single user account and advised they were working to better understand the scope of the unauthorised activity.
