Soil fertility: Global map of soil pH


Researchers create a global map of soil pH and illuminate how it changes between wet and dry climates.

Despite evolutionary inexperience, northern sockeye manage heat stress


Sockeye salmon that evolved in the generally colder waters of the far north still know how to cool off if necessary, an important factor in the species’ potential for dealing with global climate change.

DNA clue to how humans evolved big brains


Humans may in part owe their big brains to a DNA “typo” in their genetic code, research suggests.

Decoding cement’s shape promises greener concrete


Rice University materials scientists develop techniques to control the microscopic shape of cement particles for the bottom-up manufacture of stronger, more durable and more environmentally friendly concrete.

Efficiency of insect biodiversity monitoring via Malaise trap samples and DNA barcoding


An international team of scientists evaluated the performance of DNA barcoding and the barcode reference library applied to large-scale Malaise trap samples from two German sites over the span of one summer.

Scientists shed light on the climate-changing desert dust fertilizing our oceans


In the international study led by the University of Leeds, researchers have pinpointed how much phosphate ‘fertilizer’ is released from dust depending on atmospheric acid levels.

What’s the hottest Earth has ever been?


Our planet probably experienced its hottest temperatures in its earliest days, when it was still colliding with other rocky debris (planetesimals) careening around the solar system.

Powerful Earthquake Exposes Seabed Near Kaikoura


The quake was so powerful that it lifted the seabed by 2 meters (6 feet)

‘Walking sharks’ at greater risk of extinction than previously thought


New analysis of nine species that ‘walk’ by night on shallow reefs shows their range is much smaller than was known

Chernobyl disaster site enclosed by shelter to prevent radiation leaks


Reactor number four at Chernobyl, the scene of the worst nuclear accident in history, has been fully enclosed by a vast steel shelter designed to prevent radiation leaks from the site.
