Spreading of the seafloor in the Red Sea basin is found to have begun along its entire length around 13 million years ago, making its underlying oceanic crust twice as old as previously believed.
When Chauvet Cave artists created its artwork, the Pont d’Arc was already there
The Chauvet Cave, which lies by the entrance to the Gorges of the Ardèche, is home to the world’s oldest cave paintings, dating back 36,000 years. Their state of preservation and aesthetic qualities earned them a spot on the World…
Red Sea is no longer a baby ocean
It is 2,250 kilometers long, but only 355 kilometers wide at its widest point – on a world map, the Red Sea hardly resembles an ocean. But this is deceptive.
Groundwater wells worldwide run risk of running dry
As many as 20% of groundwater wells worldwide are at risk of running dry if groundwater reserves continue to decline according to a new study, which evaluated data from nearly 39 million wells from across the globe. The findings reveal…
Mars has right ingredients for present-day microbial life beneath its surface, study finds
PROVIDENCE, R.I. [Brown University] — As NASA’s Perseverance rover begins its search for ancient life on the surface of Mars, a new study suggests that the Martian subsurface might be a good place to look for possible present-day life on…

New technology could steer plastics from landfills, oceans — and into your backyard compost bin
Satellite-based monitoring is needed to prepare for catastrophic Himalayan floods
Aptly called Earth’s “Third Pole,” the Himalayan region is home to the largest ice mass outside of the planet’s polar regions. However, rising temperatures and extreme precipitation events make the region increasingly prone to a variety of natural hazards, including…

More than 5,000 tons of extraterrestrial dust fall to Earth each year
Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program conducted for…
Mountain growth influences greenhouse effect
Weathering of rocks can bind or release carbon dioxide — in active mountain ranges, carbon-dioxide release strongly dominates

Banana farming practices: Restoring soil potassium
Potassium is a major plant nutrient, and recycling it between plants and soil serves the best interest of both. Banana plant absorbs huge amount of potassium from soil and distributes between the trunk (pseudo-stem) and the fruits. Banana plants give…
Landslides: New early warning systems reduce false alarms
Many slopes in the Campania region are covered with layers of volcanic soil, the result of repeated eruptions over the course of millennia. As the impacts of climate change worsen, including the occurrence of very intense and short rainfall in…
