Oldest Enzyme in Cellular Respiration Isolated

Frankfurt, Germany — In the first billion years, there was no oxygen on Earth. Life developed in an anoxic environment. Early bacteria probably obtained their energy by breaking down various substances...

Grow Faster, Die Sooner

Munich, Germany — Bacteria are survival artists: When they get nutrition, they multiply rapidly, albeit they can also survive periods of hunger. But, when they grow too quickly, their ability to survive...

How Cells Keep Growing Even When Under Attack

Amherst, MA — In an unexpected new finding, biochemists at the University of Massachusetts Amherst report observing that a damage-containment system in stressed bacteria can become overrun and blocked,...

Algal Symbiosis Could Shed Light on Dark Ocean

East Boothbay, Maine — New research has revealed a surprise twist in the symbiotic relationship between a type of salamander and the alga that lives inside its eggs. A new paper in Frontiers in Microbiology...

Cell Diversity in the Embryo

Munich, Germany — A research team at the Max Planck Institute for Molecular Genetics in Berlin has explored the role of factors in embryonic development that do not alter the sequence of DNA, but only...

AI & Single-Cell Genomics

Augsburg, Germany — Traditional single-cell sequencing methods help to reveal insights about cellular differences and functions – but they do this with static snapshots only rather than time-lapse...

Chlamydia: Greedy for Glutamine

Würzburg, Germany — Chlamydia are bacteria that cause venereal diseases. In humans, they can only survive if they enter the cells. This is the only place where they find the necessary metabolites for...

New Insights Into Wound Healing

St. Louis, MO — When we get a wound on our skin, the cells in our bodies quickly mobilize to repair it. While it has been known how cells heal wounds and how scars form, a team led by researchers from...
