Earth may have been a “water world” three billion years ago, new research suggests
Earlier studies have suggested that the Earth was once engulfed by water and had few or no landmasses at all some three billion years ago. A recent analysis of the Earth’s mantle provides evidence in support of that idea. Published in the journal AGU Advances, it suggested that back when the planet was a molten ball of magma, its mantle […]

Human fecal bacteria found in coral reefs more than 100 miles off Houston coast
Terrestrial runoffs from extreme flooding events normally only impact nearshore ecosystems like salt marshes, seagrass beds and oyster beds. So researchers from Rice University were shocked to discover human fecal bacteria, such as Escherichia coli (E. coli), in a marine protected area about 100 miles off the coast of Houston. In particular, they found that runoff from the 2016 Tax […]

Most commercial crops grown around the world are treated with pesticides. But some farms are now switching to organic practices to avoid the risks that pesticides pose to human and environmental health. However, new research shows that past pesticide use can still “haunt” fields that have long been converted into organic farms. Published recently in Environmental […]

Harmful algal blooms can release lethal neurotoxins in the air, scientists warn
For the first time, researchers detected traces of a lethal toxin released by algal blooms in the air near a pond in Massachusetts. The discovery suggests that the neurotoxin called anatoxin-a (ATX) has the potential to become airborne. The researchers have reported the discovery in a paper published Thursday, April 1, in Lake and Reservoir Management. Harmful algal […]

New model suggests several planets in the universe might have water-rich atmospheres
Most life-forms on Earth would not survive if the planet had no atmosphere. Mars, frozen and sun-blasted, is a perfect example of what can happen to a planet that loses its atmosphere or didn’t have one to begin with. Experts have long been scouring the universe for planets with atmospheres like Earth’s to no avail. Now, a new model developed by […]

Ants found to protect plants from disease by leaking “antibiotic” chemicals
While some gardeners regard ants as pests, new research shows that the small workers can help protect crops from at least 14 different plant diseases. Published in Oikos, it revealed that ants help reduce the bacterial load and increase the germination rate of plants. The ants themselves have colonies of bacteria on their legs and thoraxes […]

Scientists discover a “space hurricane” above the North Pole
An international team of scientists has confirmed the existence of “space hurricanes” after analyzing a swirling mass of plasma spotted hundreds of miles above the North Pole. The space hurricane, which was observed by satellites in the Earth’s upper atmosphere, appeared to be raining electrons instead of water. The hurricane spun in an anti-clockwise direction […]

Future homes may soon be made of eco-friendly mushroom “bricks”
Mushrooms make for a savory, vitamin D-rich addition to a balanced diet. But it turns out, they make for more environmentally friendly “bricks,” too. Lightweight, durable and biodegradable, mushrooms are proving to be a good alternative for bricks made from clay, concrete and other conventional but polluting construction materials. How it works is agricultural waste materials […]
