Science keeps pushing the limits of what we know about the world. We write about astronomy, space research, biology and medicine. We pick studies and experiments with real impact and explain what follows from them. Sources are linked directly in the text so the context is easy to verify.
NASA’s Nancy Grace Roman Space Telescope is scheduled to launch on August 30, 2026, beginning a wide-field infrared mission designed to investigate cosmic expansion, unseen matter and planetary systems.
A newly identified star, S301, has set the speed record for known stars in the Milky Way and may offer an unusually direct way to measure the spin of the Galaxy’s central black hole.
A newly reported mathematical result narrows the range of viable ways to extend particle physics, offering guidance for future experiments without yet constituting evidence for new particles or forces.
NASA’s cancelled effort to lift the Swift observatory illustrates both the scientific value of ageing spacecraft and the unforgiving limits of hurried in-orbit servicing.
A reported experiment reconstructs a photon's quantum evolution from more than 1.4 million path contributions, offering an unusually direct operational test of Feynman's path-integral framework.
A new analysis suggests that cold, shaded terrain at the Moon’s south pole could preserve some Earth microbes in a dormant state, complicating efforts to keep future lunar science free from biological contamination.
A personalised mRNA therapy combined with pembrolizumab has produced positive Phase 3 results in high-risk melanoma after surgery, but the magnitude of benefit and long-term survival data are still awaited.
A UK natural-experiment study links lower sugar exposure from pregnancy through early childhood with a lower recorded risk of dementia decades later, but it cannot establish that sugar restriction alone caused the difference.
A long-running US trial follow-up has linked assignment to metformin with substantially lower odds of dementia, but the preliminary result is too uncertain to establish the diabetes drug as a dementia-prevention treatment.
A small Stanford-led study suggests that mapping each patient’s pain-related brain networks before stimulation may make an invasive treatment more precise, but the evidence remains preliminary.
Freshwater from Greenland is increasingly relevant to Europe’s summer climate, but the evidence points to a complex risk multiplier rather than a simple one-way cause of heatwaves.
A rapidly intensifying El Niño is raising the prospect of a historic event, but whether it has already surpassed every modern predecessor depends on the measurement used.
