Study suggests global warming has in fact accelerated in the past 15 years

You’ve probably heard it a few times: the climate is indeed warming up, but it’s all good, because the rate at which it is warming up is slowing down. But a new study published in Geophysical Research Letters analyzing ocean warming (which represents 90% of global warming) claims otherwise. Accelerating global warming Contrary to the […]

NASA releases global salinity map

NASA has, for the first time, released a global map of ocean salinity. The first thing that popped up for me was the pulse of freshwater gushing from the Amazon, but other major features are worth noticing. An invisible seam divides the salty Arabian Sea from the fresher waters of the Bay of Bengal and […]

Dolphins call each other, not by name, but by whistle

Every bottlenose dolphin makes its own distinctive sound, a high-pitched “eeee” through which they announce their presence. However, dolphins are also great at mimicking sounds, being able to copy even intricate computer generated sounds; this made researchers curious to see if dolphins can in fact mimic each other’s sound, and how they use this ability […]

The El Niño turns out to be more chaotic than previously thought

Why would the El Niño be important for the rest of us that don’t live in the western part of South America? Well because it also influences the climate in North America, Asia, Australia, Africa, even Europe perhaps.. so that basically means the whole world. The El Niño-the southern oscillation or ENSO is a sort of a […]

The island that did not exist

Who doesn’t dream of a deserted tropical island..sandy beaches made of coral sand, with crystal clear water, blue like the sky – you know what I mean. And let’s say it would be somewhere off the coast of Australia, maybe near New Calledonia. That sounds perfect.. it’s a great place, a great place to imagine. Well, […]

Avoiding a crisis The new numbers are just estimates, but they are much lower than previous studies, which put the number of […]

Corals under attack summon friendly fish

The natural world sometimes has a magnificent way of dealing with its own problems – and this is exactly the case here. Coral threatened by toxic seaweeds emit a chemical signal which draws fish to eat away the danger. When Acropora nasuta corals come into contact with the toxic seaweed Chlorodesmis fastigiata, they scream for […]

Stop Pollution or Face Severe Storms in South Asia

Hyderabad (South India): Man is the maker of his own destiny, say elders. The latest scientific studies on oceans endorse this adage. Be it  severe cyclonic storms, significant rainfall reductions, crop damages, mass mortalities and melting of Himalayan glaciers – all these could be prevented, if not minimized to a large extent, if we adopt […]

Mesmerizing light sculpture will blow your mind [VIDEO]

It’s amazing the kind of emotions and entertainment a good lights show can provide. Manipulation of optical phenomena has  been employed by artists since the invention of the first mirror, however a really dazzling display can be quite rare. Just recently, I managed to come across one of the most amazing display of art I’ve […]

The team from Scripps Institution of Oceanography at UC San Diego studied and catalogued these xenophyophores, single-celled animals […]
