Is our universe inside a black hole? New evidence from JWST galaxy images

New images from the James Webb Space Telescope of distant galaxies could support a mind-bending idea: that our universe was born in a black hole. The images show more of these galaxies spin clockwise, than counterclockwise. Lior Shamir, a computational astrophysicist from Kansas State University, says that may mean our universe inherited the spin of the black hole we’re currently living in, though he thinks its more likely that there’s something wrong with how we’re measuring objects in deep space. The study is published in the Monthly Notices of the Royal Astronomical Society. 


Modern-day Antarctic explorers go where no-one has gone before

CBC Reporter Susan Ormiston spent a month on the Canadian Navy ship HMCS Margaret Brooke as it took a team of 15 scientists on a research trip to Antarctica. She brings us the story of Kevin Wilcox, a researcher using an uncrewed sonar vehicle to map the previously inaccessible near-shore waters of the icy continent.


Finding out what juvenile sea turtles do during their ‘lost years’

Once baby sea turtles swim away from their natal beaches, they enter what marine biologists call their “lost years,” a time of critical growth spent wandering the open sea. A new study is filling in the picture of what they do during this time. The research, led by marine ecologist Katrina Phillips, involved playing a game of oceanic hide and seek to find and track over 100 sea turtles as they moved through the ocean. The work was published in the journal Proceedings of the Royal Society B.


Concrete plans to transform cement production’s CO2 waste into new building materials

Cement production is responsible for five to eight per cent of global carbon dioxide emissions. A new study suggests that waste could be made into even more construction materials. Inspired by the way sea creatures build shells, Allesandro Rotto Loria — a civil and environmental engineer from Northwestern University — says they can use CO2 to boost the process to produce carbon-negative materials that could be used in materials like plaster, cement and as a replacement for sand in concrete. Their research is in the journal Advanced Sustainable Systems. 


A Dinosaur expert goes green — with a deep look at plant evolution

Paleontologist Riley Black has authored several books on dinosaurs. But she realized she had been neglecting the organisms that made dinosaurs – and all other animals – possible: plants. Her new book, When the Earth Was Green: Plants, Animals, and Evolution's Greatest Romance, looks at how plant fossils are telling the billion-years old tale of the evolution of complex life on Earth, from creating the oxygen that we breathe, to coaxing us out of the water and onto land, and even forming the forests that humans evolved in, which shaped our very anatomy from long arms and grippy toes.
