Underwater kites, a revolutionary new technology to harvest the power of the sea, will soon supply the world with electricity.
The ravages of deforestation, wildfires, windstorms and insects on global forests during this century are revealed in unprecedented detail in a new study based on data from the NASA-U.S. Geological Survey Landsat 7 satellite.
Trees create immense negative pressures of 10′s of atmospheres by evaporating water from nanoscale pores, sucking water up 100m in a state where it should be boiling but can’t because the perfect xylem tubes contain no air bubbles, just so that most of it can evaporate in the process of absorbing a couple molecules of […]
Reuters / Mariano Caravaca Deep under the ice sheet covering Antarctica, volcanic fire still rages, a new study shows. The movement of magma, which may signal an upcoming eruption, was spotted by tell-tale signs of ‘tremor swarms’ in the west of the frigid continent. Antarctica features a number of volcanoes elevating above its surface, the […]
The scary extent of Typhoon Haiyan, which devastated the Philippines, is apparent in this shot from the International Space Station. From the orbital perch about 250 miles (400 kilometers) above Earth, the estimated Category 5 typhoon fills most of the view. On the ground, wind speeds reached as high as 235 miles an hour (378 kph), reports say.
As you probably know, the Earth is rotating on its axis. This gives us day and night. Of course it’s impossible, but what would happen if the Earth stopped spinning? Remember, this isn’t possible, it can’t happen, so don’t worry.
The strongest typhoon in recorded history, “Super Typhoon” Haiyan, has slammed into the Philippines and this is one year after Hurricane Sandy hit eastern part of the U.S.
Stunning video shows ball of fire moving down power lines after storm.
Super Typhoon Haiyan has traversed the Philippines and has entered the South China Sea. This animation shows a combination of visible and infrared imagery from the Japan Meteorological Agency’s MTSAT satellite starting November 3 at 1630Z and finishing November 8 at 1630Z.
According to some scientists, we must begin using more nuclear power in order to prevent global warming from accelerating. But that creates a huge nuclear waste problem. But scientists at the University of Sheffield think they might have found a very unique way of handing it that could make nuclear waste a problem of the past.
Turns out living animals aren’t the only ones with internal clocks. Plants also have them and they’re driven by sugar!
Everyone dies, but what do we do with those bodies? In this episode of SciShow, Hank explores the various options, from mummification to liquefaction, and everything in between.
