Many extreme events — from a rogue wave that rises up from calm waters, to an  instability inside a gas turbine, to the sudden extinction of a previously hardy wildlife species — seem to occur without warning. It’s often impossible to predict when such bursts of instability will strike, particularly in systems with a complex and ever-changing mix of players and pieces.

Jose continues to bring tropical storm conditions to southern New England although the storm has become post-tropical. NASA's Terra satellite caught a view of the storm sitting almost stationary about 100 miles from Nantucket Island, Massachusetts.

An international collaboration involving the Earlham Institute, Norwich, UK, and the Iwate Biotechnology Research Centre, Japan, has for the first time provided a genome sequence for the white Guinea yam, a staple crop with huge economic and cultural significance on the African continent and a lifeline for millions of people.

NASA-NOAA's Suomi NPP satellite provided a look at Maria's temperatures to find the strongest sides of the storm, while NOAA's GOES satellite revealed the extent of the storm in a visible image as it moved toward the Bahamas.

Fires that span across the Northern Territory and Western Australia appear to have broken out in areas that have already been burned in previous fires.  Areas that sport "burn scars", those areas that are a darker, almost red-brown color, are surrounded by fires that are anywhere from a few hours old to 7 days old.  The areas that are seven days old can be attributed to fires that spread but areas that are just a few hours old may be fires that have presumably been put out only to have them break out again.  The Northern Territory of Australia experienced a higher than normal amount of rain this past season allowing the plants and trees that fuel fires to become even more overgrown and subject to becoming fire fodder.

Hurricane Maria has caused catastrophic flooding in Puerto Rico and left a wake of heavy rainfall that NASA measured using a fleet of satellites in space. NASA satellite imagery also saw Maria's eye close up as it tracked across Puerto Rico and re-open after its exit.

Professor Tsumoru Shintake at the Okinawa Institute of Science and Technology Graduate University (OIST) yearns for a clean future, one that is affordable and powered by sustainable energy. Originally from the high-energy accelerator field, in 2012 he decided to seek new energy resources—wind and solar were being explored in depth, but he moved toward the sea instead.

Charged particles may be small, but they matter to astronauts. NASA’s Human Research Program (HRP) is investigating these particles to solve one of its biggest challenges for a human journey to Mars: space radiation and its effects on the human body.

Within Danish cattle breeding the semen of one breeding bull is used to inseminate a lot of cows. Due to the many inseminations one bull can thus father thousands of calves. Therefore, it is vital to determine whether breeding bulls carry hereditary diseases.

A partnership between QUT, the NSW Government and farmers could lead to the eventual eradication of the highly invasive African lovegrass which is threatening pastures and native grasslands Australia-wide.
