When a chromosome is lost: How do human cells react to monosomy?
Human cells are usually diploid—they contain two sets of chromosome. Cells in which one chromosome is missing from the duplicated chromosome set are generally not viable. For a long time, the mechanisms responsible for the loss of viability were un.....»»
AI can help researchers understand what viruses are up to in the oceans and in your gut
Viruses are a mysterious and poorly understood force in microbial ecosystems. Researchers know they can infect, kill and manipulate human and bacterial cells in nearly every environment, from the oceans to your gut. But scientists don't yet have a fu.....»»

Discovery may explain why Egyptian pyramids were built along long-lost Ahramat branch of the Nile
Some 31 pyramids in Egypt, including the Giza pyramid complex, may originally have been built along a 64-km-long branch of the river Nile which has long since been buried beneath farmland and desert. The findings, reported in a paper in Communication.....»»
Researchers discover new family of bacteria with high pharmaceutical potential
Most antibiotics used in human medicine originate from natural products derived from bacteria and other microbes. Novel microorganisms are therefore a promising source of new active compounds, also for the treatment of diseases such as cancer or vira.....»»
Penalties for dropping out of ecosystem services incentive programs should equal lost environmental benefits
Payment for Ecosystem Services programs (PES) are important tools that governments around the world use to improve water quality, protect forests and wildlife habitat, and sequester carbon. Under these programs, landowners—usually farmers—are pai.....»»
