Evolution is not as random as previously thought, finds new study

A new study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease, and ...

Scientists chart diversity, function and activity of global supraglacial DNA viruses

Supraglacial environments mainly consist of four main types of habitats for microbes and viruses, including snow, ice, meltwater and cryoconites (the granular sediment on glacier surfaces). A new paper published in Science ...

Gender gap in prokaryotes: Only 14.8% of bacteria and archaea named after women

In microbiology, microorganisms may be named after well-known scientific personalities to honor them. Such eponyms are common in the natural sciences, such as pasteurization (after the microbiologist Louis Pasteur).

Researchers investigate how climate change drivers reshape ocean methane and nitrous oxide cycles

The ocean is a critical life-support system for our planet through its role in global climate regulation. It absorbs most of the carbon emissions and heat trapped in the atmosphere, which result from human activities. Over ...

Researchers untangle the relationships between bacterial languages

A combination of machine learning and lab experiments has given researchers a peek into the different languages bacteria use to communicate. Understanding how bacteria communicate—and when they can't—has implications for ...

Caught in living cells: How bacteria regulate their genes to defend themselves

For the first time, it was shown in living cells how the bacterium E. coli regulates genes that help it survive in a new environment. Biochemist Fatema Zahra Rashid managed to do this using a technique she fine-tuned. Her ...

How bacteria recognize viral invasion and activate immune defenses

There's no organism on Earth that lives free of threat—including bacteria. Predatory viruses known as phages are among their most dire foes, infiltrating their cells to replicate and take over. Bacteria have evolved an array ...
