Australian researchers discover spherules collection, proof of massive asteroid that struck Earth
Asteroids do not just represent a threat to Earth. One such asteroid hit the planet when it was still forming, and researchers at the Australian National University (ANU) found proof of it in northwestern Australia. The proof are the spherules, tiny glass beads that formed from vaporised materials from the asteroid impact. The material from the impact spread worldwide with the spherules found in sea floor sediments dating back from 3.46 billion years ago, says Dr Andrew Glikson from ANU’s Plane..>> view originalAI can recreate Nobel-Prize winning experiments
From there, the algorithm learned how to change different parameters to bring the temperature down even further, and to do it with more efficiency. Primarily by adjusting a trio of laser beams. As the scientists tell it, the results were pretty impressive: The AI learned to do the experiment itself in under an hour, and its methods were beyond what even a highly trained scientist would think of. The team says that the algorithm is able to set itself up each morning and compensate for any change..>> view originalFish diversity 'will help survive warming'
Biodiversity is key to helping marine wildlife survive warming ocean temperatures, a new study has found.Scientists from Hobart's Institute for Marine and Antarctic Studies led the research, which included a survey of more than 3000 fish species in 44 countries.The study, published on Tuesday, confirms that biodiversity is a key factor needed for fish to thrive because marine communities with more fish species are more productive and more resilient to fluctuating and rising temperatures.Original..>> view originalNASA launches enormous balloon in NZ
NASA has managed to launch a massive weather balloon from New Zealand.Unfavourable winds prevented it from launching the enormous Super Pressure Balloon three times during April.But a gap in the weather on Tuesday prompted the US space agency to haul out the equipment again, sending the balloon up in the morning from Wanaka."And we have lift-off of NASA's super pressure balloon from Wanaka, New Zealand, on an around-the-world, 100+ day, potentially record breaking journey with the Compton Spectr..>> view originalThe most powerful proton conductor in the natural world is this jelly found inside a shark's head
A clear, internal jelly that helps sharks and other marine animals detect the electrical signals of their prey offers the highest proton conductivity in the natural world, according to a new study. The jelly in question is found in the 'ampullae of Lorenzini' (AoL) – an array of electrosensory organs present in cartilaginous fish such as sharks, skates, and rays. While scientists have known about the ampullae of Lorenzini for centuries, the remarkable conductivity of the jelly-like substance in..>> view originalWorld-first scanning helium microscope opens new scientific world
