Scientific American editor Mark Fischetti explains how the leaves of deciduous trees perform their annual chameleon act, changing from various shades of green to hues of bronze, orange and brilliant red.
All right-minded individuals love their animals, but some animals have been so loved, or provided such a service to humans, that they’re remembered fondly years and years after they were alive.
For the past 800,000 years, there has always been ice in the Arctic Ocean. But now climate change is causing this ice to melt at an unprecedented rate, with some people predicting that the region’s waters could be completely ice-free as early as 2016. And as the ice melts, energy companies are moving in to try and drill for some of the world’s last untapped oil and gas reserves — the very fossil fuels that caused the ice to melt in the first place.
Once-active “supervolcanoes” in northern Mars likely spewed ash and dust thousands of miles away, producing powdery deposits noticed by the NASA’s Curiosity and Opportunity rovers closer to the equator, a new study suggests.
A report compiled by over 800 UN scientists that used 9,000 scientific studies, global warming it’s not as bad as we thought, but is still a disaster.
A natural gas well is drilled near Canton, in Bradford County, Pennsylvania (Reuters) Researchers have found high levels of radioactivity, salts, and metals in water and sediment located downstream from a treatment facility which processes fracking wastewater from oil and gas production sites in Pennsylvania’s Marcellus shale formation. A Duke University team analyzed water […]
For five years an international team of experts, led by NASA emeritus glaciologist Robert Bindschadler and funded by the National Science Foundation and NASA, planned and orchestrated a mission to drill through the floating ice shelf of the Pine Island Glacier. Finally they persevered over harsh weather conditions, a short Antarctic field season, and the remote location of the glacier, and installed a variety of instruments to measure the properties of the ocean water below the ice shelf.
Call it cloudy with a low chance of meatballs. The alien world Kepler-7b — a very reflective world in big telescopes — has clouds in its upper atmosphere. And scientists have actually been able to map those out, despite the planet’s great distance from Earth (at least 1,000 light-years away.)
Featuring Michael Pollan and based on his best-selling book, this special takes viewers on an eye-opening exploration of the human relationship with the plant world, seen from the plants’ point of view. The program shows how four familiar species — the apple, the tulip, cannabis and the potato — evolved to satisfy our yearnings for […]
On the afternoon of Tuesday September 24, 2013, a 7.7-magnitude earthquake struck Balochistan province in southern Pakistan, causing widespread destruction across several districts during more than 2 minutes of powerful tremors and shaking. Sadly at least 400 people were killed (some reports say 600) and over 100,000 have been left homeless. But a weirder — if much less tragic — effect of the quake that was soon reported worldwide was the sudden appearance of a new island off the coast, a mound of mud and bubbling methane seeps rising nearly 20 meters (70 feet) from the ocean surface.
These are some of the Research Stations, the habitable structures, at the End of the world, specially built to sustain the extreme climate conditions of South and North Poles.
NASA and the U.S. Department of Homeland Security are collaborating on a first-of-its-kind portable radar device to detect the heartbeats and breathing patterns of victims trapped in large piles of rubble resulting from a disaster.
Earthquake in Pakistan creates an island off Gwadar coastline, in Pakistan. The earth moved with great force, during the 7.7 magnitude quake on Tuesday afternoon, to create this small island.
