Whale sharks gather at a few specific locations around the world – now we know why


The whale shark is the largest fish in the world, but much of its lifecycle remains shrouded in mystery. These gentle giants gather in just a handful of places around the globe – something which has long baffled scientists – but our new research has started to explain why. Better understanding of whale shark movements could help prevent further population loss in a species that has already experienced a 63% population decline over the past 75 years.

When swimming solo, the whale shark, which can grow up to 18.8 metres in length and 34 tons in weight, travels all over the world. Recently, a group of scientists tracked the remarkable journey of one whale shark across the Pacific from Panama to the Philippines. At more than 12,000 miles it proved to be one of the longest migrations ever recorded.

Yet whale sharks are known to come together at just a few specific locations around the world. Anything from ten to 500 whale sharks may gather at any one time in areas off the coasts of Australia, Belize, the Maldives, Mexico and more.

Scientists nearly double sea level rise projections for 2100, because of Antarctica – The Washington Post


If carbon dioxide emissions continue unabated, expanding oceans and massive ice melt would threaten global coastal communities, according to new projections.

Gravitational waves announcement: Scientists confirm detection of ripples in spacetime | Science | News | The Independent


Gravitational ripples in the fabric of spacetime, first predicted by Albert Einstein 100 years ago, have now been detected by scientists who believe the discovery opens new vistas into the “dark” side of the Universe. Physicists around the world confirmed that they had detected unambiguous signals of gravitational waves emanating from the collision of two massive black holes 1.5 billion light years away in deep space.
