Scientists Catch Photosynthesis in Action Researchers have snapped the very first images of photosynthesis as it happens. Photosynthesis is the process which plants use to convert light energy into chemical energy, which is then stored as sugar. Using the U.S. Department of Energy’s LCLS x-ray laser, the world’s most powerful, the researchers imaged the part […]

New evidence suggests there  might be oceans of water far beneath Earth’s surface. Northwestern University geophysicist Steve Jacobsen, along with University of New Mexico seismologist Brandon Schmandt, found evidence of water in pockets of hot magma about 645 km beneath North America within the transition zone between Earth’s upper and lower mantle. “It alters our […]

Odd X-ray Signal Might be Sign of Dark Matter Strange X-ray emissions from galaxy clusters– hundreds of galaxies connected to each other by gravity–are providing clues about mysterious dark matter. Dark matter–if it really does exist–is thought to be invisible, doesn’t produce or attract light, and makes up a majority, 84.5 percent, of the matter […]

Study Confirms Earth’s Magnetic Field is Weakening

Earth’s magnetic field is weakening, according to  measurements taken over the past six months by the European Space Agency’s (ESA) Swarm satellite constellation. The measurements–taken between January and June 2014–come from the first high-resolution results made by Swarm, and also indicate that the magnetic field has declined most dramatically in the Western Hemisphere while increasing […]

Lightning is one of nature’s most spectacular and mysterious phenomena, yet there is much scientists still don’t know about it. British researchers have found evidence that high-energy particles, which are blown toward Earth on the solar wind, play a role in triggering lightning on Earth. These energized solar particles can travel from the sun at […]

Scientists Explore Mystery of Antarctica’s Rising

An altered Antarctic landscape is one of the rarely discussed side effects of accelerated ice melting. For years as the ice grew in Antarctica, its weight compressed the ground beneath it. But when the ice melted and this weight was reduced, the ground sprang back, rebounding over time. However, the ground in the Northern Antarctic […]

New Dating System Could Reveal Secrets of Earth’s Ancient Climate

Scientists have a new tool in the quest to learn more about Earth’s ancient climate, including the mechanisms that plunged our planet into and out of ice ages. The new tool is a scientific technique called radiometric krypton dating, which recently allowed researchers to accurately determine the age of a 120,000-year-old Antarctic ice core sample. […]

Study: Air Pollution Over Asia Found to Impact Global Weather

Researchers from Texas, California and Washington recently compared air pollution data provided by the Intergovernmental Panel on Climate Change for the years 1850 through 2000 and found that human-made atmospheric particulates (aerosols) from Asia are having an impact on the Pacific storm track, which is a critical driver of global atmospheric circulation that influences weather […]

Earth’s Natural Climate Control Keeps Planet Livable

A new hypothesis explains why Earth has remained habitable despite natural events that have robbed other planets in our solar system of their ability to host and sustain life. As the character Goldilocks exclaimed in the classic fairytale, The Story of the Three Bears, Earth is the one planet in our solar system that’s “just […]

Are Oceans of Water Hiding Beneath Earth’s Surface?

Scientists have discovered the first-ever earthly sample of a water-rich mineral they say provides new proof that there are vast oceans of water deep beneath the Earth’s surface. The team, led by Graham Pearson from Canada’s University of Alberta, found a mineral called ringwoodite in a sample of rock taken from a Brazilian riverbed. Ringwoodite […]
