  1. Astronomers have revised the mass of exoplanet GJ 3378b, 25 light-years away, from 5.26 to 2.3 times Earth's mass, placing it firmly within its star's habitable zone where liquid water could exist. The super-Earth receives about 90% of the radiation Earth gets from the sun, making it a promising target in the search for potentially habitable worlds.[1]

  2. Scientists at John Innes Center have engineered wheat with supersized starch granules, a breakthrough that could lead to healthier, slower-digesting bread and pasta while benefiting industries from flour milling to pharmaceuticals. Larger granules digest more slowly, potentially reducing blood sugar spikes linked to type 2 diabetes.[2]

  3. Physicists at the University of Vienna have increased the lifetime of magnons, tiny magnetic waves that can carry quantum information, by nearly 100 times, reaching up to 18 microseconds. The breakthrough shows that the main limitation is material purity rather than physics, suggesting future improvements could come from better manufacturing.[3]

  4. The LINK spacecraft has successfully established communications after launching on Northrop Grumman's final Pegasus XL rocket to rescue NASA's 21-year-old Swift Observatory. The robotic spacecraft will approach Swift over the coming weeks and boost it to a higher orbit to prevent the telescope from falling back to Earth.[4]

  5. Researchers have demonstrated for the first time in real time that immune cells use catecholamines—neurotransmitters like dopamine and adrenaline—to communicate using the same chemical signals as nerve cells. The discovery at the Universities of Münster and Bochum opens new understanding of how the immune system is regulated.[5]

  6. The UN World Meteorological Organization warned that El Niño conditions have set in and will rapidly strengthen into a strong event between July and September, increasing the likelihood of heatwaves, droughts, and heavy rainfall worldwide. The agency is stepping up early warning support to help governments and humanitarian agencies prepare.[6]

  7. Astronomers using Japan's Super-Kamiokande detector have found a 2.6-sigma excess of neutrino events that may represent the first indication of the Diffuse Supernova Neutrino Background—the accumulated neutrinos from all supernova explosions throughout cosmic history. While below the 5-sigma discovery threshold, the signal was presented at the Neutrino 2026 conference.[7]

  8. Researchers at the University of Pennsylvania developed a prime-editing platform called fPE7max that achieves approximately 90% editing efficiency in filamentous fungi, unlocking silent gene clusters that produced eight new molecules, three with early anti-cancer activity. The tool could accelerate drug discovery from fungal sources.[8]

  9. The James Webb Space Telescope has discovered a new massive barred spiral galaxy designated M1149-BSG-z5 at high redshift, where bar structures are expected to be suppressed due to the drastically different cosmic environment of the early universe. The finding challenges understanding of galaxy evolution.[9]

  10. A paleontological study analyzing nearly 9,000 size changes across 450 million years found that marine animals consistently shrink during environmental crises, with the effect most pronounced during warming phases. The findings, published in PNAS, suggest current climate change will cause marine organisms to decrease in size.[10]
