The World Health Organization has declared the Ebola outbreak in Congo and Uganda an international emergency.
The outbreak is caused by the Bundibugyo strain of the Ebola virus. According to the WHO, it is not a global pandemic, but there is concern about regional spread due to cross-border movement, insecurity and a lack of vaccines or treatments specific to the strain.

A slice of the COSMOS-Web map, showing galaxies across nearly 14 billion years of the universe's history. The vertex on the left indicates the current time; moving outward, each galaxy is located at its own distance in cosmic time, until you reach a time when the universe was less than a billion years old. Light yellow areas show the dense clusters and filaments of the cosmic web, and dark areas indicate the nearly empty spaces between them. Credit: Hossein Hatamnia, UC Riverside

A new study led by the University of Michigan has found that water in the interstellar comet 3I/ATLAS is particularly rich in deuterium. This isotope of hydrogen is relatively rare in the solar system, and the finding allows researchers to learn about planetary formation processes that operated elsewhere in the galaxy.

Interstellar comet 3I/ATLAS likely formed in an environment very different from the solar system

The figure illustrates how changes in genetic control lead to changes in the shape and structure of animals during evolution. The upper part shows larvae of two species of Drosophila: Drosophila melanogaster (left), which has dense rows of tiny hairs, and Drosophila sechellia, which has lost many of these hairs during evolution. These differences arise from changes in the expression of the shavenbaby gene during the embryonic stage (center of the figure). The lower part shows the control region of the shavenbaby gene, which includes a large number of control sequences called enhancers, which are important for ensuring stable expression of the gene. In D. sechellia, four of the enhancers have lost their activity, each through a different molecular mechanism – deletion of essential sequences, loss of binding sites for transcription factors, acquisition of repressive activity, and even exposure of previously existing repression. As a result, gene expression decreases and the tiny hairs disappear.
