Climate change in Ireland will have many impacts – some of which will be life-threatening – according to a range of experts based here. This means, they all agree, that action can no longer be delayed.

This report features contributions Dr Ina Kelly, consultant in public health medicine, HSE; Dr Audrey Morley, ocean scientist NUIG; Dr Jimmy Murphy, coastal erosion engineer at UCC MaREI and Dr Ruth Kelly, zoologist, TCD, and was first broadcast on Drivetime on RTE Radio 1 on 20th December ’17.

 

My weekly science news round up on East Coast FM: weight loss; mindfulness; ancient Egypt; super volcano; Chinese space station

The latest science news from around the world

A group of scientists say there is no evidence for many of the benefits claimed for mindfulness (Source: http://www.positivepsychologyprogram.com)

 

Every two lbs overweight knocks nine weeks off your life

Source: Telegraph, UK

  • Study of 600,000 people study link between longevity and lifestyle
  • Smoke pack of cigs per day, die seven years earlier on average
  • Edinburgh University researchers did this as a so-called big data project, which means analysing and cross referencing vast amounts of data.
  • If you are two stone overweight, then it will take, on average, six months off your life.
  • Data came from Europe, North America and Australia, via the UK Biobank.
  • But… also found that life is extended by one year for every year a person stays in education after school, on average. That’s a massive effect.
  • Life expectancy continuing to increase, and in the UK it stands now at 79.5 years for a man, on average, and 83.1 for a woman.
  • But, Public Health England found this year that the average ‘healthy’ average life expectancy – the number of years a person can live largely free of illness – is less than the age people get the state pension

Little proof mindfulness meditation works, say scientists

Source: Scientific American

  • Scientists in the US now asking where is the proof that mindfulness works? Question asked by a group of 15 prominent psychologists and cognitive scientists in the journal Perspectives on Psychological Science.
  • Lots of studies have been done on mindfulness and it has been reported to relieve stress, pain and even slow ageing.
  • But, these researchers are critical of these studies because they say they are poorly designed, they have inconsistent definitions are what mindfulness actually is, and often do not use a control group to rule out the placebo effect.
  • Only some 9 per cent of studies on mindfulness has been tested in clinical trials, one report said, and meta analysis of mindfulness research not impressive.
  • In 2014, a review of 47 meditation trials, involving over 3,500 people found that no evidence mindfulness enhanced enhanced attention, curtailed substance abuse, helped sleep or controlled weight.
  • Mindfulness meditation and training is now a huge industry, so there are vested interests promoting its effectiveness, the scientists state.
  • Less than 25 per cent of trials on mindfulness monitor potential negative effects and that is causing worry among scientists too.
  • The 2014 review did find some benefits, modest benefits, for anxiety, depression and pain from the use of mindfulness.
  • A reputable trial this year found that mindfulness attention training reduced self perceived stress, but not the stress hormone cortisol. What does it mean?
  • Another trial found that mindfulness increased the thickness of the prefrontal cortex around of the brain, which is associated with complex behaviour, decision making and shaping the personality.

Ancient Egypt brought down by volcanoes and climate change

Source: Independent UK

  • Volcanic eruptions caused riots and rebellions against Ptolemaic rule and Cleopatra was one of those leaders.
  • Ancient Egypt relied on monsoon weather to provide water irrigate the nile delta region, as does 70 per cent of the globe still today
  • Researchers at TCD and Yale looked at the historical records and used climate modelling methods (working backwards) to do this study.
  • Summer floods helped crops to grow, fed population and were the fundamental basis for the wealth of ancient Egypt at this time 350BC to 30 BC or so.

Yellowstone Super Volcano could erupt inside decades causing global volcanic winter

Source: Independent UK

  • The last time it erupted was 630,000 years ago and created the Yellowstone caldera, which is 40 miles wide.
  • The volcano is so big that if it erupted, it could choke the Earth’s entire atmosphere with ash, blocking out a lot of sunlight, causing temperatures to dip, and this would continue for years.
  • That last massive eruption, scientists at Arizona State have found, occurred following two influxes of fresh magma into the magma chamber.
  • The temperatures increased around the volcano as this happened over decades, not centuries, as previously thought.
  • This shows that the the yellowstone volcano could become dangerous inside decades, at any point, when temperatures start to rise.
  • Large parts of the USA would be covered in dangerous ash if it erupted, the Earth would dramatically cool, sunlight would struggle to get through and the impact would last more than a decade. Life would get very tough, esp in US.

Chinese space station will crash to Earth in months

Source: Guardian UK

  • The 8.5 tonne orbiting laboratory (two large male bull elephants) is now out of control, and in a death spiral, and the ISS will follow perhaps as earth as 2020.
  • The Tiangong-1, or heavenly palace, lab was launched in 2011 as part of China’s push to become a space superpower.
  • Visited by taikonauts including China’s first female taikonaut Liu Yang in 2012.
  • Much of the craft will burn up in the atmosphere, but scientists in the west estimate that pieces as large as 100kg (16 stone man) will crash to Earth anytime between now and April 2018.
  • Impossible to predict when and where the pieces will fall scientists say.
  • No-one has been hurt by space debris falling to Earth, but in 1979 NASA’s 77-tonne Skylab space station crashed to the ground with some large pieces landing outside Perth.
