There are lots of scary-looking things in the sea: sharks, giant squids, jellyfish. But the thing we really should be scared of most is the growing trash pile swirling in our oceans. There are 5 trillion pieces of trash floating out there, and it’s ending up in the stomachs of many sea animals.
Can trees cause pollution? Short answer: yes -- mismanaged forests can cause nutrient pollution. Cypress and cedar trees in Japan are causing massive amounts of nitrogen runoff into local streams, resulting in harmful algae blooms.
It's technically possible for each state to replace fossil fuel energy with entirely clean, renewable energy, experts say. A new report is the first to outline how each of the 50 states can achieve such a transition by 2050. The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.
The Boy Who Played with Fusion had its beginnings in 2010 when, as a contributing editor at PopSci, I discovered a small and unusual community of makers, high-energy hobbyists who were taking on both the formidable theory and the precision engineering of applied nuclear science. The idea that self-taught amateurs outside the Big Science world of billion-dollar laboratories were tinkering with nukes—fusing atomic nuclei, transmuting elements, constructing atom-smashing machines in DIY laboratories—was both intriguing and unsettling.
Clean, drinkable water is unfortunately out of reach for hundreds of millions of people around the world, contributing to a vicious cycle of poverty and disease. People who have to spend large amounts of time finding safe water to drink don't have time for other things like education or work, and contaminated water often harbors deadly diseases. But there is hope, in the form of nanotech filters, light-based water purifiers, and an ancient Egyptian seed.
Carrying liquids up a hill usually involves a pump, or a lot of buckets. But now it seems water can do some of the heavy lifting itself.

Physicists have chilled molecules to just a smidgen above absolute zero — colder than the afterglow of the Big Bang.
A grin without a cat" is how Lewis Carroll describes the Cheshire Cat's mysterious way of disappearing while leaving its grin behind in his 1865 classic, Alice in Wonderland. The fanciful character raises a question that has captured physicists' attention over the past few years: can an object be separated from its properties?
Scientists see ripples of a particle-separating wave in primordial plasma, a key sign of quark-gluon plasma and evidence for a long-debated quantum phenomenon that's called a "chiral magnetic wave" rippling through the soup of quark-gluon plasma created in energetic particle smashups.
Some people may roll their eyes at the idea of UFO sightings, while others are certain they have seen alien craft. Now a data visualisation expert has created a map of the US showing almost 90 years of official UFO sightings, including information such as the time of day they are typically noticed in different months.

For around twelve weeks, Karapetyan and his unit were stationed at Buynaksk, in the Republic of Dagestan, doing their utmost to lessen the alarming expansions across Europe by the Nazis. On one particular morning, and quite out of the blue, a Buynaksk-based police officer visited Karapetyan’s camp and shared with him some astonishing news.
Milk, a staple of life since time immemorial, is common in faerie lore. Practically all of the fae folk accept milk as an offering, are quick to steal it from farmers, and occasionally offer it directly to humans (recall the man who died for rejecting the banshee’s buttermilk).
Reality doesn’t exist until it’s measured, at least for very small things, new research has found.
Life is dependent upon a lot of coincidences, but there’s only one that was so improbable that physicists laughed at the very idea of it. Here’s why something known as the “beryllium bottleneck” should have choked out all life before it even got started.
Elon Musk's SpaceX has officially asked for permission to build a constellation of 4,000 satellites capable of beaming the Internet to the most remote regions of the earth. The plan, outlined in a request to the Federal Communications Commission, would transform Musk's rocket company into a new Internet service provider to compete with the likes of Verizon and Comcast. And you thought you were having a productive day.
Can computer software invent scientific theories and ideas as well as crunch numbers? That's the suggestion being put forward by Michael Levin and Daniel Lobo, two computer scientists at Tufts University, Massachusetts in the US, who have programmed a computer to come up with its own scientific hypothesis on one of biology's most well-known mysteries.
Scientists have shown that the Earth is not so much the planet of the apes as the planet of the DNA molecule – calculating that there is enough of it in the world to fill a billion shipping containers.
