Muons: ‘Strong’ evidence found for a new force of nature

Science
Reidar Hahn / FermiLabFrom sticking a magnet on a fridge door to throwing a ball into a basketball hoop, the forces of physics are at play in every moment of our lives.All of the forces we experience every day can be reduced to just four categories: gravity, electromagnetism, the strong force and the weak force.Now, physicists say they have found possible signs of a fifth fundamental force of nature.The findings come from research carried out at a laboratory near Chicago.The four fundamental forces govern how all the objects and particles in the Universe interact with each other.For example, gravity makes objects fall to the ground, and heavy objects behave as if they are glued to the floor.The UK's Science and Technology Facilities Council (STFC) said the result "provides strong evidence ...

Coronavirus: Bat virus hunters find new evidence

Science
Getty ImagesScientists say coronaviruses related to Sars-CoV-2 may be circulating in bats across many parts of Asia.A virus that is a close match to the Sars-CoV-2 virus, which causes Covid-19, has been discovered in bats at a wildlife sanctuary in eastern Thailand.The researchers predict that related coronaviruses may be present in bats across many Asian nations and regions. Their discovery extends the area in which related viruses have been found to a distance of 4,800km (2,983 miles).The study is reported in Nature Communications.Writing in the journal, the researchers said the sampling site (Thailand only) and sampling size was limited, but they were confident that coronaviruses "with a high degree of genetic relatedness to Sars-CoV-2 are widely present in bats across many nations and ...
Study: CBD users tout medical benefits on social media amid lack of scientific evidence

Study: CBD users tout medical benefits on social media amid lack of scientific evidence

Health
Oct. 15 (UPI) -- Use of cannabidiol, or CBD, has skyrocketed in recent years as it has been promoted for a range of medical conditions from autism to arthritis, and testimonials on social media reflect that the marketing is working. Researchers at the University of California, San Diego, found that roughly 90% of CBD users in the Reddit community r/CBD tout the drug as an effective treatment, but they note in an analysis published Thursday by JAMA Network Open there is a lack of scientific evidence supporting the claims. Advertisement Users posting in the community recommended CBD for mental health conditions such as autism and depression -- in 65% of posts -- as well as orthopedic ailments such as arthritis, muscle cramps and musculoskeletal pain -- in 26% of posts -- the data showed. Th...
Evidence of potential war crime by Saudi coalition in Yemen

Evidence of potential war crime by Saudi coalition in Yemen

World
A Sky News investigation has discovered evidence of a recent potential war crime in northern Yemen by the Saudi-led coalition, which is backed by the US and Britain.There's already growing controversy over why Britain is still supporting a campaign which has led to the country being declared the world's biggest humanitarian disaster. The Sky team travelled hundreds of kilometres along dry riverbeds and through rocky, inhospitable terrain and winding mountain paths to reach the remote village of Washah near the Yemeni-Saudi border. Once there, we were led by foot up narrow hill trails to the site of an airstrike on a family home. We were the first outsiders to reach the site - and the first independent journalists to examine the area and talk to multiple eyewitnesses as well as survivors of...
Paleontologists find evidence of new mass extinction 233 million years ago

Paleontologists find evidence of new mass extinction 233 million years ago

Science
Sept. 16 (UPI) -- Paleontologists have unearthed evidence of a new mass extinction that occurred during the Late Triassic, some 233 million years ago. The extinction event, which scientists dubbed Carnian Pluvial Episode, was characterized by significant reductions in biodiversity and the loss of 33 percent of marine genera. Advertisement In a new paper, published Wednesday in the journal Science Advances, researchers suggest the episode may have created the ecological space for the emergence of a variety of important modern plant and animal lineages -- including conifers, insects, dinosaurs, crocodiles, lizards, turtles and mammals. Through analysis of both paleontological assemblages and geological evidence, researchers confirmed that biodiversity declines coincided with stark chemical ...
