Bronze Age herders were less mobile than previously thought

Bronze Age pastoralists in what is now southern Russia apparently covered shorter distances than previously thought. It is believed that the Indo-European languages may have originated from this region, and these findings raise new questions about how technical and agricultural innovations spread to Europe.

Salt-based mosquito-control products are ineffective

A new study by a bevy of expert mosquito researchers offers an important warning to consumers: Products claiming to reduce mosquito populations with salt-water solutions are ineffective. In a series of lab tests using nine mosquito species, researchers found no evidence that adult mosquitoes are killed by salt ingested at concentrations used in several popular mosquito-control products.

Artificial intelligence reveals hundreds of millions of trees in the Sahara

(University of Copenhagen) There are far more trees in the West African Sahara and Sahel than most would expect. A combination of artificial intelligence and detailed satellite imagery allowed a team from the University of Copenhagen and international collaborators to count all trees across a 1.3 million km2 area of West Africa.

Final two journals in the 2020 pilot program use Subscribe to Open to publish volumes OA

(Annual Reviews) Nonprofit publisher Annual Reviews is pleased to announce that the 2020 volumes of the Annual Review of Environment and Resources and the Annual Review of Nuclear and Particle Science have been converted from gated to open access. All articles in these volumes are published under a CC BY license and the back volumes, dating from 1976 and 1952, respectively, are now freely available. These are the final two journals included in the 2020 pilot program for Subscribe to Open.

Management of a popular game fish, the smallmouth bass

For recreational fishing enthusiasts, the thrill of snagging their next catch comes with discovering what’s hooked on the end of the line. In many freshwater streams and rivers — across the central and eastern parts of the U.S. — anglers are often catching a popular freshwater game fish: the smallmouth bass. Now, scientists have discovered a new level of biodiversity within that species.

Light pollution alters predator-prey interactions between cougars and mule deer in western US

A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance.

AI methods of analyzing social networks find new cell types in tissue

In situ sequencing enables gene activity inside body tissues to be depicted in microscope images. To facilitate interpretation of the vast quantities of information generated. Researchers have now developed an entirely new method of image analysis. Based on algorithms used in artificial intelligence, the method was originally devised to enhance understanding of social networks.

Neurons in a visual brain area of zebrafish are arranged as a map for catching prey

Spotting, pursuing and catching prey – for many animals this is an essential task for survival. Scientists now show in zebrafish that the localization of neurons in the midbrain is adapted to a successful hunting sequence.
