Warmer water is flowing toward the East Antarctic ice sheet, according to our alarming new research that reveals new potential drivers of global sea level rise. Author Laura Herraiz Borreguero Physical oceanographer, CSIRO Alberto Naveira Garabato Professor, National Center for Oceanography, University of Southampton Jess Melbourne-Thomas Transdisciplinary Researcher & Knowledge Broker, CSIRO The research, published today in Nature Climate Change, suggests changes in water circulation in the Southern Ocean could jeopardize the stability of the East Antarctic ice sheet. The ice sheet, the size of the United States, is the largest in the world. Changes in water circulation are caused by shifting wind patterns, and are linked to factors including climate change. Warmer waters and rising sea levels can damage marine life and threaten human coastal settlements. Our findings underscore the urgency of limiting global warming to below 1.5℃, to prevent the most catastrophic...

DNA from fossils unearthed in southern China dating back 14,000 years suggest that Native Americans had East Asian roots Fossils found in China suggest Native Americans may have genetic roots in East Asia The data will help us understand ‘how humans change their physical appearance by adapting to local environments over time,’ said study co-author Bing Su. By Christopher Carbone For Dailymail.Com Published: 11:31 a.m. EDT, 14 July 2022 | Updated: 11:32 am EDT, 14 July 2022 DNA from ancient fossils in southern China has revealed that Native Americans may have roots in East Asia. Scientists compared the genetic information of Late Pleistocene-era fossils with the genetic information of humans around the world. They found that the bones belonged to someone closely related to the ancestors of Native Americans in East Asia. Archaeologists have successfully sequenced the fossil genome.

We can model the motion of the planets in the Solar System quite accurately using Newton’s laws of physics. But in the early 1970s, scientists noticed that this didn’t work for disk galaxies — the stars on their outer edges, away from the gravitational force of all matter at their center — moving much faster than Newton’s theory predicted. This led physicists to propose that an invisible substance called “dark matter” exerts an extra gravitational pull, causing the stars to accelerate – a theory that has become very popular. However, in a recent review, my colleagues and I suggested that observations at multiple scales are much better explained in an alternative theory of gravity proposed by Israeli physicist Mordehai Milgrom in 1982 called Milgromian or Mond dynamics – requiring no material not visible. Mond’s main postulate is that when gravity becomes very weak, as it does at the edges of galaxies, it begins to behave differently from Newto...
