Gene-Edited Beagles May Offer Future Option for Dog Allergy Sufferers [Core Summary] American researchers have used CRISPR gene-editing technology to modify beagles, successfully reducing expression levels of major proteins that trigger human allergies. This breakthrough research, published in the latest scientific journal, offers potential for tens of millions of dog allergy sufferers worldwide to coexist with dogs in the future. The study has also sparked discussions about animal ethics and the boundaries of genetic modification. ...

A SpaceX Falcon 9 rocket body is set to crash into the Moon’s surface, with parts of the impact potentially visible from Earth, reports WIRED.

The Okefenokee Swamp in Georgia, USA, has been officially designated as a UNESCO World Heritage Site. After years of application efforts, North America’s largest pristine swamp ecosystem has gained international recognition, bringing new opportunities for ecological protection and sustainable development.

SpaceX’s Starship completed its 13th test flight, achieving what the company called the ‘softest splashdown ever,’ marking a major breakthrough in reusable rocket technology.

Core Summary Scientists analyzing a meteorite that crashed into a New Jersey home earlier this year have discovered amino acids and other fundamental chemicals that constitute life. Published in the journal Meteoritics & Planetary Science, this finding provides precious samples for studying the chemical evolution of the early solar system and the origin of life on Earth. Event Details According to ABC News, the meteorite crashed into a residential property in New Jersey earlier this year, causing damage to the house. Scientists quickly collected fragments and conducted detailed analysis. The research revealed multiple types of amino acids—the basic units that make up proteins and key chemical components necessary for life. ...

Core Summary A Tyrannosaurus rex fossil named “Gus” sold for $50.1 million at Sotheby’s auction house in New York, setting a new all-time record for dinosaur fossil auctions. The 67-million-year-old skeleton attracted global attention from collectors and museums. Details Sotheby’s announced on July 14 that the well-preserved T. rex skeleton went through intense bidding before finally selling for $50.1 million. The buyer’s identity has not been disclosed, but the fossil is reportedly intended for public display. This price far exceeds any previous dinosaur fossil auction record, reflecting the continued surge in demand for rare paleontological specimens in the collector’s market. ...

Core Summary A SpaceX Falcon 9 rocket booster has successfully completed its 36th launch and landing recovery, setting a new world record for the number of flights by a reusable orbital-class rocket. This milestone achievement further demonstrates the maturity and commercial viability of rocket reuse technology, laying a solid foundation for dramatically reducing space transportation costs and accelerating humanity’s space exploration progress. Event Details According to Space news, the Falcon 9 booster designated B1081 successfully delivered its payload to the intended orbit in the latest mission, then precisely landed on the droneship in the Atlantic Ocean, completing its historic 36th flight. The booster has previously executed multiple Starlink satellite deployment missions. ...

Six mysterious pieces of space debris discovered on Forrest Beach in Queensland; officials are investigating their origin.

Core Summary According to CNN, new research suggests that close relatives of the “hobbits” (Homo floresiensis) who lived on the Indonesian island of Flores may not have possessed the highly advanced cognitive abilities previously assumed. Scientists analyzing new fossil material found that these ancient humans may have taken a simpler evolutionary path, challenging the academic view that “small brains equal high intelligence.” This discovery offers a fresh perspective on understanding the diversity of human evolution. ...

Summary NASA’s Perseverance rover has discovered complex organic matter in Mars’ Jezero Crater, marking a potentially historic finding in the search for extraterrestrial life. The organic molecules were detected in sedimentary rock samples from an area that was once an ancient lake bed. Details The discovery was made using the rover’s SHERLOC and PIXL instruments, which can identify organic molecular structures on the Martian surface. While organic matter can form through non-biological processes, the complexity of the molecules found suggests a possible connection to ancient microbial activity. ...
