Battery electrode materials need to do a lot of things well. They need to be conductors to get charges to and from the ions that shuttle between the electrodes. They also need to have an open structure that allows the ions to move around before they reach a site where they can be stored. The Continue Reading
At 1pm on Thursday, we encourage you to join us for a live chat with Zeke Hausfather, a climate scientist and researcher at Berkeley Earth. We’ll talk a bit about how he got into climate science and ended up at Berkeley Earth and the role that organization plays in the world of climate science. It Continue Reading
A wavy polar jet stream can bring icy storms further south Science History Images / Alamy Stock Photo Increasingly erratic winter weather in the northern hemisphere isn’t a result of the polar jet stream getting more wavy, according to new research – although climate change is making winter storms more intense in other ways. The Continue Reading
Present-day disk galaxies often contain a thick, star-filled outer disk and an embedded thin disk of stars. For instance, our own Milky Way galaxy’s thick disk is approximately 3,000 light-years in height, and its thin disk is roughly 1,000 light-years thick. How and why does this dual disk structure form? By ***yzing archival data from Continue Reading
Climate change and habitat loss are affecting animal populations around the world and reptiles such as South Australia’s own endangered pygmy bluetongue are susceptible to higher temperatures and declining long-term rainfall trends. Flinders University scientists are working on securing a sustainable future for the burrow-dwelling endemic skink (Tiliqua adelaidensis) by blockessing their suitability to cooler Continue Reading
In general, evolution is a long, slow process of tiny changes pblocked down over generations, resulting in new adaptations and even new species over thousands or millions of years. But when living things are faced with dramatic shifts in the world around them, they sometimes rapidly adapt to better survive. Scientists recently found an example Continue Reading
As NASA prepares for its Artemis II mission, researchers at the agency’s Glenn Research Center in Cleveland are collaborating with The Australian National University (ANU) to prove inventive, cost-saving laser communications technologies in the lunar environment. Communicating in space usually relies on radio waves, but NASA is exploring laser, or optical, communications, which can send Continue Reading
Today, all non-Africans are known to have descended from a small group of people that ventured into Eurasia after around 50 thousand years ago. However, fossil evidence shows that there were numerous failed dispersals before this time that left no detectable traces in living people. In a paper published in Nature this week, new evidence Continue Reading
When scientists first sequenced the human genome in 2003, they revealed the full set of DNA instructions that make a person. But we still didn’t know what all those 3 billion genetic letters actually do. Now Google’s DeepMind division says it’s made a leap in trying to understand the code with AlphaGenome, an AI model Continue Reading
To save elephant populations from extinction, the international community banned the sale of their ivory — but selling mammoth ivory remains legal, and the two are difficult to tell apart, especially for non-experts. This leaves a possible loophole for sellers of poached ivory to exploit. Now stable isotope blockysis could provide a cheap, rapid option Continue Reading
