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.

Radioactive cloud over Europe had civilian background

A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in 2017, is still bothering Europe's radiation protection entities. German researchers now found out that the cloud did not originate from military sources but rather from civilian nuclear activities.

Repairing thousands of disease-causing mutations

Researchers have created a new searchable library of base editors -- an especially efficient and precise kind of genetic corrector. Using experimental data from editing more than 38,000 target sites in cells with 11 of the most popular base editors (BEs), they created a machine learning model that accurately predicts base editing outcomes. Called BE-Hive, the library is free and open to the...
