Nature Catalysis, Published online: 26 May 2026; doi:10.1038/s41929-026-01538-3 PtSn catalysts are most effective for propane dehydrogenation but structural tunability remains challenging. Now the use of molecular complex precursors unlocks access to subnanometre alloyed PtSn clusters within silicalite-1. The Pt in the clusters undergoes diverse and rapid interconversion among different electroni…

BackgroundPulmonary arterial hypertension (PAH) is a severe multifactorial disease associated with impaired pulmonary hemodynamics, leading to right ventricular (RV) hypertrophy and failure. Induction of inducible nitric oxide synthase (iNOS) and/or activation of cannabinoid CB1 receptor (CB1R) is associated with pro-inflammatory, pro-fibrotic, and pro-hypertrophic effects. Therefore, we tested t…

Osteoporosis, a prevalent systemic skeletal disorder, poses a significant health risk to the elderly population, arising from a multitude of factors that disrupt bone homeostasis. This delicate balance is primarily regulated by the dynamic interplay between osteoblasts and osteoclasts. When this equilibrium is perturbed, osteoporosis can ensue. Traditional Chinese Medicine (TCM) posits that the k…

_Australasian Journal of Philosophy_. forthcomingWork on testimonial injustice (Fricker 2007) and testimonial violence (Dotson 2011) shows that marginalised epistemic agents are unjustly undermined as testifiers when dominant agents fail or refuse to hear, understand, or believe their testimony. This work has been pathbreaking. But I argue that it restricts our focus to one way in which epistemic…

Nature Communications, Published online: 26 May 2026; doi:10.1038/s41467-026-73745-2 This work demonstrates a self-powered, event-nature artificial spherical compound eye that achieved ultrafast and panoramic motion sensing under 0 V, particularly suitable for resource-limited drones and robotics.

Cool, drizzly weather is settling across Southern California this week, as a cold system moves in from the north.

Multiple videos show a rare "fireball" meteor breaking apart with a flash of emerald light over the erupting Mount Mayon. Initial reports suggested that the falling space rock hit the volcano, but this was untrue.

We’ve been reporting a lot lately on the negative impacts of satellite constellations. And unfortunately it’s time for another article about a paper pointing out the potential hazards of them. This one, by lead author Conner Barker of University College London, focuses on the pollution caused by rocket launches - and admittedly contains some good news, but also a cautionary tale that policy maker…

With concerns about childhood obesity and screen use sky-high, cuts to primary PE are an unforced error With remarkably poor timing, days before closing a consultation on children’s social media use, the government announced last week that it is cutting an annual £320m sports premium for primary schools in England. A new scheme worth £193m will cover secondaries too, and resurrect a previous mode…

The chancellor can point to growth and lower inflation, but weak job data, flat living standards and uncertain productivity are no reason to cheer In October 1991, the then chancellor Norman Lamont said he thought he saw some “green shoots” of recovery. He was ridiculed, as Britain was in the midst of a deep recession that it would not clamber out of until the following summer. Insouciant in the …

For velocity and speed, there are four quantities totally: velocity, speed, average velocity, and average speed. Speed can be described though magnitude of velocity. However average velocity and ...

Guardian readers respond to an article by Zoe Williams which argued that cutting the welfare bill should start with pensions Zoe Williams seeks to stimulate a debate about pensions and intergenerational inequality, but seems to have overlooked the issues surrounding the funding of public-sector defined-benefit (DB) pension schemes ( All this talk about ‘difficult’ cuts, yet the largest part of Br…

Our life expectancy is not simply our personal responsibility, writes Jennie Popay Having spent several decades as a researcher in the health equity field, I was irritated to see that well-worn, misleading trope about personal responsibility for poor health being given the oxygen of publicity by the Guardian ( At least 80% responsibility for ill health in old age down to individual, study says, 2…

TL;DR In Parts 1 – 6 of this series, we validated read paths across six engines. This Part 7 answers the write question: Can you use Delta Lake, Apache Iceberg, or Apache Hudi on FSx for ONTAP S3 Access Points? No. All three transactional table formats fail to write on FSx S3 AP due to fundamental S3 API limitations: Format Failure Point Error Root Cause Delta Lake Commit (write) 501 Not Implemen…

Over the last few years, I’ve spent a lot of time thinking about operational architecture. Not just: frontend frameworks APIs deployment pipelines infrastructure But how entire systems evolve over time. That line of thinking eventually led me somewhere unexpected: Back to PHP. More specifically: back to WordPress. And honestly, I didn’t expect that. Because like many developers, I spent years cha…

Age limits and changes to allegedly addictive design features could be in place by the end of the year Labour is expected to announce a social media crackdown within weeks as the prime minister, Keir Starmer, on Tuesday said he would act “very, very quickly” despite splits between campaigners and child safety experts on what the new rules should be. New limits on social media access for children …
