Why does nature create patterns? – the Conversation
The reason patterns often appear in nature is simple: The same basic physical or chemical processes occur in many patterned substances and organisms as they form. Whether in plants and animals or rocks, foams and ice crystals, the intricate patterns that happen in nature come down to what’s happening at the level of atoms and molecules…
How deep is the ocean? – the Conversation
If you wanted to measure the depth of a pool or lake, you could tie a weight to a string, lower it to the bottom, then pull it up and measure the wet part of the string. In the ocean you would need a rope thousands of feet long. In 1872 the HMS Challenger, a British Navy ship, set sail to learn about the ocean, including its depth. It carried 181 miles (291 kilometers) of rope…
We studied more than 1,500 coastal ecosystems – they will drown if we let the world warm above 2℃ – the Conversation

Hurricanes push heat deeper into the ocean than scientists realized, boosting long-term ocean warming, new research shows – the Conversation
Seven years ago an exceptionally strong El Niño took hold in the Pacific Ocean, triggering a cascade of damaging changes to the world’s weather. Indonesia was plunged into a deep drought that fueled exceptional wildfires, while heavy rains inundated villages and farmers’ fields in parts of the Horn of Africa. The event also helped make 2016 the planet’s hottest year on record. Now El Niño is back…
My art uses plastic recovered from beaches around the world to understand how our consumer society is transforming the ocean – the Conversation
“I am obsessed with plastic objects. I harvest them from the ocean for the stories they hold…Each object has the potential to be a message from the sea – a poem, a cipher, a metaphor, a warning. My work collecting and photographing ocean plastic and turning it into art began with an epiphany in 2005, on a far-flung beach at the southern tip of the Big Island of Hawaii…
Curious Kids: If plastic comes from oil and gas, which come originally from plants, why isn’t it biodegradable? – the Conversation
Question from Neerupama, age 11, Delhi, India..
To better understand why plastics don’t biodegrade, let’s start with how plastics are made and how biodegradation works…
