Martian Volcanoes Bigger, Faster Growing than Expected

Written by Alice Scarsi

Scottish scientists have used meteorites fallen to Earth to recreate the evolution of a volcano on Mars, in a first-ever attempt made in history. The space rocks analysed hid more than 90 million years of information on the Red Planet’s volcanoes.

They allowed scientists to identify from which volcano they came from, how fast it grew and how long it was active. Mars has the largest volcanoes in the solar system. Olympus Mons is more than 370 miles wide and over 13 miles high, more than twice the height of Mount Everest, the tallest mountain on Earth.

Great Barrier Reef ‘Dying’ Scare Exposed as #FakeNews

Written by James Delingpole

The Great Barrier Reef is recovering ‘surprisingly’ fast, according to Australia’s state propagandist ABC. Optimism is rising among scientists that parts of the Great Barrier Reef that were severely bleached over the past two years are making a recovery.

Scientists from the Australian Institute of Marine Science this month surveyed 14 coral reefs between Cairns and Townsville to see how they fared after being bleached.

Life first emerged in ‘warm little ponds’

Written by Ian Johnston

Life on Earth began up to 4.5 billion years ago as carbon-rich meteors bombarded the planet and leached the essential elements into “warm little ponds”, according to new research. It was in this nutrient-rich broth that the first self-replicating molecules, with the first genetic code for life, were born.

DNA surgery on embryos removes disease

Written by James Gallagher

Precise “chemical surgery” has been performed on human embryos to remove disease in a world first, Chinese researchers have told the BBC.

The team at Sun Yat-sen University used a technique called base editing to correct a single error out of the three billion “letters” of our genetic code. They altered lab-made embryos to remove the disease beta-thalassemia. The embryos were not implanted.

Three scientists who unravelled how our bodies tell time have won the 2017 Nobel Prize for physiology or medicine. The body clock – or circadian rhythm – is the reason we want to sleep at night, but it also drives huge changes in behaviour and body function. The US scientists Jeffrey Hall, Michael Rosbash and Michael Young will share the prize.

Antarctic ozone depletion due to Erebus volcano gas emissions

Written by Zuev, Zueva, Savelieva & Gerasimov

New Antarctic study shows  hydrogen chloride and sulphur dioxide emitted by Erebus volcano are a significant factor in ozone depletion.  Erebus volcanic gases reach the ozone layer via cyclones and the polar vortex.  High Erebus volcanic activity in the early 1980s resulted in the ozone hole area increase.
