Scientists find thousands of earthquakes in a perfectly straight line in Alaska, revealing a hidden 'microplate' - Live Science

A trip to Mars may be more feasible than previously thought, suggests a new study led by Northwestern Medicine, UT Southwestern and UT Houston that tracked the heart function of 13 astronauts during roughly six-month missions aboard the International Space Station.

AbstractConventional cholesterol liposomes have poor stability, rapid clearance, and toxicity. This study used Rg3 to replace cholesterol for constructing curcumin-loaded liposomes (PCRL) and evaluated their potential for enhanced hepatocellular carcinoma therapy. Curcumin-loaded liposomes were prepared with Rg3 (PCRL) and cholesterol (PCCL) via thin-film hydration. Physicochemical properties, protein corona, in vitro behavior, in vivo tumor targeting, antitumor efficacy, and biosafety were assessed in H22 tumor-bearing mice. PCRL exhibited smaller particle size, superior storage/plasma stability, and comparable membrane packing to PCCL. Protein corona analysis showed reduced adsorption of immunoglobulin-like and complement proteins, prolonging blood circulation > 24 h and enhancing tumor accumulation.

AbstractPleural effusion is a common clinical finding with heterogeneous causes, including infection, malignancy, heart failure, tuberculosis, pulmonary embolism and systemic disease. Because patients often encounter pleural effusion as an imaging finding rather than as a diagnosis, short-video platforms may shape early understanding, anxiety and care-seeking behaviour. Evidence on the quality of this content is lacking. We conducted a cross-sectional content analysis of publicly available pleural effusion–related short videos on Douyin and Bilibili. The Mandarin search term “胸腔积液” (pleural effusion) was entered on 15 May 2026 and the first 150 results returned under each platform’s default ranking were screened.

Superconductivity has many important practical applications, including creating powerful magnets used in high-resolution medical scans, transporting electricity efficiently, and building ultra-sensitive measuring devices. Until now, understanding exactly what lay behind this unique phenomenon at high temperatures has eluded scientists over many decades. But pioneering research , led by physicists at the University of Bristol and published this week in the journal Nature Physics, has identified the vital mechanism which explains how electrons in these copper-oxide high-temperature superconductors combine to transmit power with no loss of energy – the 'superconductive' state of infinite electrical conduction. Study co-lead author Nigel Hussey , Professor of Physics at the University of Bristol, said: "Superconductivity is a remarkable, almost magical, phenomenon which has long fascinated famous physicists and resulted in various breakthroughs recognised with Nobel Prizes over the decades. "The processes which facilitate higher temperature superconductivity, however, have remained a source of mystery and fascination.
