Mixture and migration brought food production to sub-Saharan Africa

A new interdisciplinary study reports on 20 newly sequenced ancient genomes from sub-Saharan Africa, including the first genomes from the Democratic Republic of the Congo, Botswana, and Uganda. The study documents the coexistence, movements, interactions and admixture of diverse human groups during the spread of food production in sub-Saharan Africa.

Discovery of oldest bow and arrow technology in Eurasia

The origins of human innovation have traditionally been sought in the grasslands and coasts of Africa or the temperate environments of Europe. More extreme environments, such as the tropical rainforests of Asia, have been largely overlooked, despite their deep history of human occupation. A new study provides the earliest evidence for bow-and-arrow use, and perhaps the making of clothes, outside...

Protecting bays from ocean acidification

As oceans absorb more human-made carbon dioxide from the air, a process of ocean acidification occurs that can have a negative impact on marine life. But coastal waterways, such as Chesapeake Bay, can also suffer from low oxygen and acidification. New research identifies one way to protect these waterways -- the presence of submerged aquatic vegetation (SAV).

Parasites and the microbiome

In a study of ethnically diverse people from Cameroon, the presence of a parasite infection was closely linked to the make-up of the gastrointestinal microbiome, according to a research team.

NASA's Mars rover drivers need your help

You may be able to help NASA's Curiosity rover drivers better navigate Mars. Using the online tool AI4Mars to label terrain features in pictures downloaded from the Red Planet, you can train an artificial intelligence algorithm to automatically read the landscape.

NASA names first woman to head human spaceflight

The NASA official who managed the inaugural private crewed flight into space last month has been promoted to become the first female head of human spaceflight, the agency said Friday, as it prepares to return people to the Moon in 2024.
