• Researchers published the most thorough study of cosmic expansion in the journal Astronomy & Astrophysics on April 10, combining decades of research to derive the most precise Hubble constant yet while confirming that tension between early and late-universe measurements persists. • The study, launched at an International Space Science Institute Breakthrough Workshop in Bern, Switzerland in March 2025, expanded the cosmic distance ladder into a comprehensive survey called the Local Distance Network, achieving a goal considered 'potentially unreachable' a decade ago. • Study co-author Richard Anderson from the University of Göttingen stated that the Hubble tension reveals that 'something's missing' in the current understanding of basic physics on cosmological scales.

Researchers say hardship is a direct legacy of welfare benefit cuts imposed by Tory governments in recent yearsMore than a fifth of all “austerity generation” British children have been scarred by poverty for at least half their childhood, a direct legacy of the welfare benefit cuts imposed by Conservative governments in recent years, research reveals.The proportion of children born after 2013 who spent at least six of their first 11 years of life in hardship surged after ministers froze working age benefits levels and imposed policies such as the two-child limit, it found.

Analysis of six extreme heatwaves found when temperature and humidity were accounted for, all were potentially deadly for older peopleExtreme heat is already creating “non-survivable” conditions for humans in heatwaves that have killed thousands and likely many more, according to new research that warns people are more susceptible to rising temperatures than first thought.Scientists re-examined six extreme heatwaves between 2003 and 2024 and found that when temperature, humidity and the body’s ability to stay cool were accounted for, all were potentially deadly for older people.

Despite hostile rhetoric Trump let a Russian ship break his blockade – could it herald a Venezuela-style outcome?When a sanctioned Russian oil tanker, the Anatoly Kolodkin, docked at Cuba’s Matanzas oil terminal on Tuesday, unloading 700,000 barrels of crude, it was not immediately clear why the ship had been allowed to pass through Donald Trump’s oil blockade.In January, the US president had proclaimed on social media: “THERE WILL BE NO MORE OIL OR MONEY GOING TO CUBA – ZERO!” yet last week he told reporters, “If a country wants to send some oil into Cuba right now, I have no problem with it” – and waved the Russian ship through.

Reports on English policies seen in Wales as relating to whole of UK contribute to widespread confusion, researchers sayUK media is failing to report properly on devolved issues in Wales, leaving voters ill-informed about May’s Senedd elections, a report has found.A Cardiff University study of more than 3,000 news items found repeated patterns in coverage across different broadcasters and platforms, including not signposting whether an issue was relevant to England or England and Wales only, widespread references to “the government” rather than “the UK government”, and the use of “you” and “your” in contexts that apply only to people living in England.

• Researchers from Binghamton University and University of Virginia developed a machine-learning system that analyzed over 55 million scientific papers and patents to identify truly disruptive research that changes the direction of science. • The new metric, published in Science Advances, measures "disruptiveness" — the degree to which a paper pulls a field away from its earlier path — and successfully identifies major simultaneous discoveries often overlooked by traditional citation-based measures. • The study addresses a critical gap in how science evaluates impact, recognizing that scientific progress occurs through abrupt changes rather than incremental steps, helping identify overlooked breakthrough moments in research history.

Merlin could disappear in worst-case scenario, with British isles facing ecological ‘point of no return’The merlin, Britain’s smallest bird of prey, is one of more than 200 species that will become extinct in the UK if action is not taken to curb emissions and unsustainable land use, a study has claimed.According to the UK Centre for Ecology & Hydrology (UKCEH), there is a 20-year window in which decisions on climate and land use will determine the fate of dozens of Britain’s native species.

• A new American College of Cardiology study of over 6,800 U.S. adults shows consuming more than nine daily servings of ultra-processed foods raises heart attack, stroke, or death risk by 67% compared to one serving. • Each additional serving increases risk by over 5% overall and more than 6% among Black Americans, with findings presented at the ACC Annual Scientific Session in New Orleans on March 28-30. • Dr. Michele Arthurs of Kaiser Permanente advises checking labels and strategies like pre-eating healthy meals or pairing chips with oranges to cut intake.

Researchers believe behavioral gap, which may hold true across species, is probably product of less fear of harassment in cities Anyone who has lived long enough in a city can tell you – with time, you just stop noticing strange new things. A unicycling bagpiper. A person changing clothes on the subway. Murals that transform streets into tart.Coyotes in cities seem to be bolder as well and less afraid of new experiences. That’s according to a new study that researchers conducted at more than a dozen sites across the US, comparing urban and rural coyotes’ reaction to new stimuli. Continue reading...
