Komatsu continues its advancement in alternative engine technology with the release of its first commercial rigid-frame dump truck with a “power agnostic” platform for running on diesel, battery electric or hydrogen fuel cells. The company released its new Power Agnostic 930E mining truck at this week’s MineExpo trade show in Las Vegas. The concept truck

No, Bitcoin mining does not use 8% of global electricity although Bill Maher thinks so Liam 'Akiba' Wright · 22 hours ago Insights Bitcoin Mining Fact-checking Bill Maher's claim: Bitcoin uses less than 1% of global electricity. On a recent episode of “Real Time with Bill Maher,” Maher claimed that crypto consumes 8% of global

Paleontologists in Brazil have examined the well-preserved fossilized remains of two mammal-precursor species: Brasilodon quadrangularis and Riograndia guaibensis . The findings offer critical insights into the development of the mammalian jaw and middle ear, revealing evolutionary experiments that occurred millions of years earlier than previously thought. An artist’s impression of Brasilodon quadrangularis (left) and Riograndia

Dubbed EndoMac progenitors, the newly-discovered type of cell has the potential to enhance the future of tissue repair and generation, according to a team of scientists headed by South Australian Health and Medical Research Institute researchers. Angiotensin II-induced vascular inflammation involves early expansion of EndoMac progenitors in vivo. Image credit: Williamson et al., doi: 10.1038/s41467-024-51637-7.

Around 66 million years ago, the Chicxulub asteroid impact triggered mass extinction, mega-tsunamis and a spell of global warming that lasted for around 100,000 years. Although NASA’s Double Asteroid Redirection Test (DART) mission demonstrated that near-Earth objects can be successfully targeted, deflecting the most dangerous asteroids will require energy concentrations akin to nuclear explosions. However, targets
