Top-Funded AI Database Startup Pinecone Considers a Sale
When the artificial intelligence boom began a few years ago, investors flocked to startups that helped businesses transform and store proprietary data in a format AI could understand, known as a vector database. The technology allowed businesses to use a customized AI chatbot to search or ...

Owning two Pixel phones running GrapheneOS made me both chuckle and tear up a little. It’s such an amazing operating system that I’m planning to start making monthly donations to support the project.
I had my Pixel 6a since early May 2023, but yesterday I upgraded to a Pixel 9a because the speakers and earpiece microphone on my 6a had started to fail badly, and the battery was showing its age.
I’m glad I made the upgrade, and now people can hear me clearly on the phone again.

The calamitous Eaton and Pacific Palisades fires in Los Angeles in January show we need a new way of thinking about fire:
as not only natural disaster,
but also environmental threat with a high risk of long-term harms to health.
The ramifications of toxic contamination in large areas of Los Angeles for public safety and health are likely to be significant.
Consider the spike in both heart and lung disease reported after the 2023 Lahaina fire on Maui.
And then …

Opinion | Los Angeles Wildfires Left the City With a Toxic Mess
Urban wildfires are becoming public health emergencies.

The average surface temperature of the Mediterranean Sea is at record level for this early in summer, at 3°C above the 1982-2011 average. Could end up well above the 2023-2024 record summer peaks (Jul-Aug) of 28°C.

Automating Thematic Review of Prevention of Future Deaths Reports: Replicating the ONS Child Suicide Study using Large Language Models
Prevention of Future Deaths (PFD) reports, issued by coroners in England and Wales, flag systemic hazards that may lead to further loss of life. Analysis of these reports has previously been constrained by the manual effort required to identify and code relevant cases. In 2025, the Office for National Statistics (ONS) published a national thematic review of child-suicide PFD reports ($\leq$ 18 years), identifying 37 cases from January 2015 to November 2023 - a process based entirely on manual c…

Such a great head, this head of mine!
Apparently I had opened a GitHub account in october 2023 and forgot all about it. 🤪

Working on the #perl 5.42 update for #nixpkgs - unfortunately perl-cross hasn't been released for 5.42 yet which is a bit of a blocker. In general it feels like the declining interest in maintaining #CPAN packages are going to be a problem over time. For instance EV hasn't had a release since 2023 and needed a patch to work with 5.42

GWTC-4.0: Updating the Gravitational-Wave Transient Catalog with Observations from the First Part of the Fourth LIGO-Virgo-KAGRA Observing Run
Version 4.0 of the Gravitational-Wave Transient Catalog (GWTC-4.0) adds new candidates detected by the LIGO, Virgo, and KAGRA observatories through the first part of the fourth observing run (O4a: 2023 May 24 15:00:00 to 2024 January 16 16:00:00 UTC) and a preceding engineering run. In this new data, we find 128 new compact binary coalescence candidates that are identified by at least one of our search algorithms with a probability of astrophysical origin $p_{\rm astro} \geq 0.5$ and that are n…

Open Data from LIGO, Virgo, and KAGRA through the First Part of the Fourth Observing Run
LIGO, Virgo, and KAGRA form a network of gravitational-wave observatories. Data and analysis results from this network are made publicly available through the Gravitational Wave Open Science Center. This paper describes open data from this network, including the addition of data from the first part of the fourth observing run (O4a) and selected periods from the preceding engineering run, collected from May 2023 to January 2024. The public data set includes calibrated strain time series for each…

Cada vez que veo noticias sobre las IAs como esta pienso que aquí nos enteramos de estas miserias, se comparten, se comentan... pero ¿y fuera? Por ejemplo, la gente en general es consciente de lo que supone para su privacidad que una IA grabe y "transcriba" una conversación confidencial con su médico?

A Tale of Two Shocks
It was the best of times, it was the worst of times, . . . - for the thermal/suprathermal particle populations in the vicinity of two traveling interplanetary shocks observed by Solar Orbiter on 2023-11-29 07:51:17 UTC and 2023-11-30 10:47:26 UTC at $\sim 0.83$ astronomical units from the Sun. We investigate these two very dissimilar shocks and elucidate their non-equilibrium features. We do not provide explanations of all observed features, our aim is to report them here for future reference…

Tracing the light: Identification for the optical counterpart candidates of binary black-holes during O3
The accretion disks of active galactic nuclei (AGN) are widely considered the ideal environments for binary black hole (BBH) mergers and the only plausible sites for their electromagnetic (EM) counterparts. Graham et al.(2023) identified seven AGN flares that are potentially associated with gravitational-wave (GW) events detected by the LIGO-Virgo-KAGRA (LVK) Collaboration during the third observing run. In this article, utilizing an additional three years of Zwicky Transient Facility (ZTF) pub…

Spatiotemporal evolution of UV pulsations and their connection to 3D magnetic reconnection and particle acceleration
Quasi-periodic pulsations (QPPs) are a common feature of impulsive solar flare emissions, yet their driving mechanism(s) remain unresolved. We study long-period (3.4 min) QPPs in the M3.7 flare on Feb 24, 2023, using SDO/AIA and Solar Orbiter/STIX to pinpoint their source and driver. We analyzed UV and HXR emissions from four subregions covering the flare ribbons and footpoints of the erupting filament. We find the QPP characteristics varied significantly across these regions. The strongest UV …

Can fractal dimension distinguish between grand-design and flocculent spiral arms?
About two-thirds of disk galaxies host spiral arms, ranging from well-delineated grand-design spirals to fragmented flocculent spiral galaxies. We introduce fractal dimension $D_B$ as a non-parametric measure to distinguish between grand-designs and flocculents. We calculate the $D_B$ of 197 grand-designs and 322 flocculents from SDSS DR18, using the samples of \citet{Buta..2015} and \citet{Sarkar..2023}. Our calculated median values of $D_B$ are $1.29^{+0.06}_{-0.04}$ and $1.38^{+0.05}_{-0.06}…
