When we interbred with Neanderthals, they were usually the fathers

• Scientists using the Rubin Observatory identified over 11,000 new asteroids in our solar system. • Discoveries include hundreds of distant objects beyond Neptune, expanding knowledge of outer solar system. • This US-based telescope project enhances planetary defense and solar system mapping efforts.

• An international team including University of Oxford, University of Michigan, and others used the Gemini laser and plasma to compress light, creating the most powerful light ever in a lab. • The technique acts as a 'quantum magnifying glass' by focusing light waves, enabling direct study of Quantum Electrodynamics (QED) interactions with the quantum vacuum. • Published in Nature on April 22, 2026, it bridges a 20-year gap between theory and observation, per Prof. Brendan Romey of Queen's University Belfast.

• Stanford University neuroscientists discovered a blood-based biomarker (phosphorylated tau-217) that reliably predicts Alzheimer's disease development one to two decades before cognitive decline appears, according to research published April 20. • The biomarker was identified through analysis of blood samples from 2,500 cognitively healthy individuals followed for 15 years, with positive predictive value exceeding 92% in early-stage detection. • The finding could enable preventative therapies targeting amyloid and tau proteins before neurodegeneration becomes irreversible, potentially transforming Alzheimer's treatment approaches.

• Researchers at the University of Washington created an artificial photosynthesis prototype converting sunlight directly into storable chemical fuels with 13% efficiency, surpassing previous laboratory records of 8-10%. • The system uses engineered nanostructures and novel catalysts to split water and fix carbon dioxide, producing methanol as a liquid fuel suitable for existing energy infrastructure, detailed in Nature Energy on April 21. • The breakthrough could enable large-scale production of carbon-neutral synthetic fuels without competing for agricultural land, addressing both climate and energy security challenges.

• MIT scientists unveiled a new quantum computing design achieving stable operation of 1,024 qubits simultaneously, surpassing previous records and demonstrating significant error correction capabilities reported on April 21. • The innovation uses a novel topological qubit design with error rates of 0.1% per operation, enabling computations previously impossible due to quantum decoherence, according to research published in Physical Review Letters. • The breakthrough could accelerate commercial quantum computing applications in drug discovery, materials science, and optimization problems within 2-3 years, researchers said.

• A comprehensive analysis from the National Center for Atmospheric Research shows US carbon dioxide emissions fell 8.2% year-over-year in Q1 2026, driven primarily by renewable energy sources now supplying 34% of national electricity generation. • Solar and wind capacity additions reached record levels with 42 gigawatts of new renewable infrastructure installed in 2025, according to data released by the Department of Energy and independent research institutions. • Climate scientists attribute the acceleration partly to state-level climate policies and federal incentives from the 2024 Clean Energy Investment Act, though transportation and industrial sectors still require significant emission reductions.

• Researchers from Woods Hole Oceanographic Institution reported that Atlantic cod and other commercial fish populations have rebounded 34% over the past four years following strict catch quotas and marine protected areas implemented in 2022. • Population surveys conducted across 850,000 square kilometers of Atlantic waters show biomass increases in previously depleted stocks, with detailed findings presented at the American Fisheries Society conference on April 19. • The recovery demonstrates that science-based fisheries management can restore ecosystems within a decade, providing a model for international ocean conservation efforts.

• NASA's Perseverance rover discovered extensive water ice deposits beneath Mars' surface in Jezero Crater using advanced ground-penetrating radar technology, with findings suggesting accessibility for future human missions. • The subsurface ice layers extend up to 300 meters deep and contain an estimated 5 million metric tons of water ice, according to data released by NASA's Jet Propulsion Laboratory on April 21. • Scientists believe the water deposits could support long-term human habitation and fuel production, making Mars exploration more feasible for sustained presence beyond current rover missions.

• SpaceX's Starship completed its 15th integrated flight test on April 21, achieving full-stack booster catch at Starbase, Texas, and a controlled splashdown in the Indian Ocean for the Super Heavy upper stage. • The mission marked the first successful reentry and splashdown of Starship with active thermal management systems, demonstrating technological readiness for crewed lunar missions planned for 2027. • Flight duration extended to 68 minutes with multiple payload bay experiments conducted, including deployment of prototype satellite constellations and in-space refueling demonstrations.

• Researchers at CERN's Large Hadron Collider detected rare Higgs boson decay patterns that deviate from Standard Model predictions, suggesting potential physics beyond current theoretical frameworks. • The analysis examined 150 billion particle collisions collected over two years, revealing a 3.2 sigma deviation in the boson's decay pathways, announced on April 20 by the ATLAS and CMS collaborations. • The findings could indicate undiscovered particles or fundamental forces and represent significant progress toward understanding the universe's most elusive particles.

• The FDA granted accelerated approval to a CRISPR-based gene therapy for severe sickle cell disease on April 20, marking the first approved genetic treatment editing patient blood cells to produce functional hemoglobin. • Clinical trials demonstrated 95% of treated patients experienced elimination or near-elimination of vaso-occlusive crises within 12 months, with durable responses observed for over two years post-treatment. • The therapy addresses a disease affecting approximately 100,000 Americans, primarily of African descent, offering potential cure for patients previously reliant on pain management and blood transfusions.

• The US Geological Survey documented unusual seismic activity patterns beneath Yellowstone National Park over the past 72 hours, including 127 small earthquakes concentrated in a previously stable subsurface region. • Monitoring stations recorded magnitude 2.0-3.8 events with distinct directional propagation, suggesting possible magma chamber adjustments rather than typical tectonic shifts, announced April 21 by USGS geophysicists. • Scientists emphasize current volcanic threat levels remain low based on gas emissions and ground deformation data, though real-time monitoring has been intensified as a precautionary measure.
