• Mina Guli's 40 Marathons Across Seven Continents

  An Australian athlete who is running 40 marathons, across seven deserts and seven continents in seven weeks has gone from the freezing cold of Antarctica to the heat of the Simpson Desert in just a matter of hours. Mina Guli has faced blistering heat and bone-numbing cold, all manners of deadly creepy crawlies and is literally putting her life on a line for a cause -- to raise awareness of global water scarcity. Mina Guli running in the Tabernas Desert, Spain. Picture Kelvin Trautman Guli, th..

• Our Addiction To Coal Is Forcing Us To Farm Coral

  

  Farming coral -- this is what our addiction to coal is forcing scientists to explore, as we brace for a mass bleaching event in the Great Barrier Reef and more sobering ocean acidification research emerges.New data in Nature, collected on One Tree Reef in the southern Great Barrier Reef, provides the first in-situ evidence that ocean acidification, driven by global warming and carbon pollution, is stunting coral growth.The researchers artificially reduced the level of ocean acidity to pre-indus..

• Universe's “missing” matter found by intense energy burst

  

  Powerful cosmic “flash” reveals previously hidden atoms in-between galaxies Fast radio burst releases enough energy in one millisecond to rival our Sun for 10,000 years Radio burst came from quiet, old galaxy, surprising scientists UNTIL recently, half the universe’s ordinary matter was “missing”, but now it’s been found thanks to an incredibly powerful flash that gives off as much energy in one millisecond as our Sun emits in 10,000 years. Scientists believe the universe comprises 70 per cen..

• Emissions cuts critical to avoid blistering heat waves

  

  BARCELONA — Without a reduction in planet-warming emissions, blistering heat waves of the strength that now typically occur once every 20 years could happen annually on 60 per cent of the earth’s land areas by 2075, scientists have warned.And intense heat waves — defined as three exceptionally hot days in a row — will become far more extreme if greenhouse gas emissions continue unchecked, said a new study published in the journal Climatic Change. The researchers said a worsening of extreme he..

• How flower pots can save sealife

  

  Marine ecologist Rebecca Morris installing new seawall pots along the Sydney Harbour at the Royal Botanic Gardens.A NEW “rock pool” program is hoping to bring marine life lost to foreshore development back to Sydney Harbour. After a successful trial at Blackwattle Bay, along the Glebe foreshore, which resulted in a rejuvenation of the area’s marine life and attracted 28 unique species to its waters, the City of Sydney council is extending the project to the harbour.Involving the addition of spec..

• Take in the beauty of Pluto's frozen north pole canyons

  

  The icy valleys of Pluto's north pole shimmer in a new NASA photo taken by the New Horizons spacecraft.  The false color image reveals the dwarf planet's complex and craggy terrain as it appeared only 45 minutes before the probe made its closest flyby of Pluto in July 2015.  It also shows that Pluto's north pole is pretty strange looking. The dwarf planet's high elevations in the region are somewhat yellow-tinged, a coloration "not seen elsewhere on Pluto," according to NASA. Lower elevations t..
