Although plants do not have nervous systems, they respond to stress with chemical and electrical signals that are remarkably similar to those of animals, a new study has found. The findings, published in the journal Nature Communications, could help to explain why certain plant-derived drugs work so well in humans. At the center of it all is the neurotransmitter GABA (gamma-aminobutyric acid), which humans and animals, as well as plants, release when they are stressed out.
It is often held aloft by environmental campaign groups as an example of one of the last remaining regions of unspoiled habitat left in the world. But instead of being a pristine rainforest untouched by human hands, the Amazon appears to have been profoundly shaped by mankind. An international team of researchers have published evidence that suggests the Amazon was once home to millions of people who lived and farmed in the area now covered by trees. The scientists claim the Amazon basin was a major centre of crop domestication that saw at least 83 native species being cultivated to some degree.
The universe is teeming with planetary music. Sounds exists in the form of electromagnetic vibrations and can be detected using specially designed instruments developed by NASA. The “voice of Earth” and the sounds of other planets and stars are absolutely breathtaking.
Lightning is an unruly beast; hard to predict and filled with surprises. And according to the National Weather Service, so far this year lightning strikes have killed at least 20 people in the United States, which is almost double the norm. Behind those strikes are some pretty wild facts. Consider the following
Stonehenge inspires awe, but there’s an even more mysterious ancient scene in Laos. The Plain of Jars consists of thousands of prehistoric stone vessels scattered over hundreds of square kilometers near Phonsavan, in the northeastern part of the country—a hilly area, despite the “plain” in the name. The huge jars form a surreal sight—some are up to ten feet tall and weigh several tons. It’s an archeological wonder that experts still haven’t pinned down.
In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research is revealing how the primordial soup created the amino acid building blocks, and there is widespread scientific consensus on the evolution from the first cell into plants and animals. But it’s still a mystery how the building blocks were first assembled into the proteins that formed the machinery of all cells. Now, two long-time University of North Carolina scientists – Richard Wolfenden, PhD, and Charles Carter, PhD – have shed new light on the transition from building blocks into life some 4 billion years ago.
For the first time in 50 years, mysterious ‘X-Files’ sounds have been recorded from the edge of space. A helium balloon built by a student for a NASA project captured the eerie hisses and whistles 22 miles above the Earth’s surface.The bizarre noises were captured using equipment designed and built by Daniel Bowman, a graduate student at the University of North Carolina at Chapel Hill, according to LiveScience. The instruments recorded atmospheric infrasound – sound waves at frequencies below 20 hertz. Since infrasound is below human hearing range, the noises can only be heard when the recording is sped up. “It sounds kind of like ‘The X-Files,'” Bowman said. He added that the intensity of the sounds came as a shock, stating that he was “surprised by the sheer complexity of the signal.”

Today’s earthquake in Nepal is reportedly a 7.8 – 7.9 magnitude. What does that mean in actual terms? We’ve all heard earthquakes described by magnitude number, and yet most of us have a relatively vague or distorted perception of what these numbers mean in the real world. This video illustrates the variation of energy released in easy-to-understand terms.
The Lyrid Meteor shower will reach its peak late on April 22 (Earth Day) when as many as 20 meteors per hour are expected to whiz through the night sky.
A World Health Organization group’s controversial finding that the world’s most popular herbicide “probably is carcinogenic to humans” was based on a thorough scientific review and is a key marker in ongoing evaluations of the product, the scientist who led the study said Thursday.
A 1,000-meter wide asteroid (called ‘2014-YB35’) will pass by Earth on Friday, March 25, 2015 – traveling at more than 23,000 mph.
As a solar eclipse plunges parts of the world into darkness this Friday, two other rare if less spectacular celestial events will be taking place, too: a Supermoon and the Spring equinox.
New video shows how Solar Flare Energy from the sun is being used to control the earth’s weather and accelerate the Fraudulent Climate Change Agenda to get all nations to submit to the New World Order.
