UK experts want ban on tackling in school rugby
More than 70 UK doctors and health experts have written an open letter addressed to government ministers, chief medical officers and children’s commissioners, calling for a ban on tackling in school rugby games, The Guardian reports. “The majority of all injuries occur during contact or collision, such as the tackle and the scrum,” the letter says. “These injuries, which include fractures, ligamentous tears, dislocated shoulders, spinal injuries and head injuries, can have short-term, life-long and life-ending consequences for children.” Rugby is a compulsory part of the UK physical education curriculum from the age of 11 in many boys’ schools, particularly in the independent sector, The Guardian says. The letter’s authors urged schools to move to touch and non-contact versions of the game. “Repeat concussions have been found to have a link to cognitive impairment, and an association with problems such as depression, memory loss and diminished verbal abilities. Children also took longer to recover to normal levels on measures of memory, reaction speed and post-concussive symptoms.” The Rugby Football Union said it took player safety “extremely seriously” and that recent changes meant young players underwent a “gradual and managed” introduction to the contact version of the game.
PLOS ONE paper provokes social media backlash
Retraction Watch reports that a paper on the biomechanics of the hand published in PLOS ONE has provoked a social media backlash for using apparently religious language in the abstract, introduction and conclusion. “In conclusion, our study can improve the understanding of the human hand and confirm that the mechanical architecture is the proper design by the Creator for dexterous performance of numerous functions following the evolutionary remodeling of the ancestral hand for millions of years.” Some commentators on Twitter described the publication of the paper as “an absolute joke” and “a big problem”. A spokesperson for PLOS was quoted by Retraction Watch as saying: “PLOS has just been made aware of this issue and we are looking into it in depth. Our internal editors are reviewing the manuscript and will decide what course of action to take. PLOS’ publishing team is also assessing its processes.” The corresponding author is listed as Cai-Hua Xiong, based at Huazhong University of Science and Technology in China.
Australian health system “underprepared” for heatwaves
A Climate Council report has found Australia’s health system is underprepared to deal with longer, hotter and more intense heatwaves, the ABC reports. “The Climate Council report … found nursing homes and medical centres across the country may not be equipped with necessary back-up energy and water supplies in extreme heat. The council noted several states had upgraded heat and health warning systems since the deadly heatwaves in 2009, but the lack of a streamlined response system was putting lives at risk. The report found heatwaves put pressure on health services, with emergency call-outs jumping almost 50 per cent and heart attacks almost tripling in the heatwaves of January and February 2009. By 2030, Australia’s annual average temperature is predicted to rise by 0.6 to 1.3 per cent, with the globe continuing to heat up to the end of the century, the report said. The report highlights the global problem of heatwaves, pointing to 55 700 deaths during the Russian heatwave in 2010, and 3700 killed in India and Pakistan in May 2015.”
Astronaut Scott Kelly and his twin a boon to science
Commander Scott Kelly has returned to Earth after 340 days on board the International Space Station (ISS) and a raft of scientists and doctors can’t wait to get their hands on him, Forbes reports. Any astronaut coming home is scrutinised, but Cmdr Kelly’s return was particularly anticipated because he has a twin brother. Retired astronaut Mark Kelly has spent the past year on Earth, providing scientists conducting NASA’s Twins Study with the chance to conduct the ultimate “controlled experiment”. Weightlessness can lengthen the spine and body by up to 3%, can cause loss of muscle — most notably in the heart — and bone mass; cause the head to swell; and cause dizziness and fainting on return to Earth. There are also issues of radiation exposure without the shield of the Earth’s atmosphere.
