Leaking away essential resources actually helps cells grow

Experts have been unable to explain why cells, from bacteria to humans, leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites—substances involved in ...

Galactic cosmic rays affect Titan's atmosphere

Planetary scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) revealed the secrets of the atmosphere of Titan, the largest moon of Saturn. The team found a chemical footprint in Titan's atmosphere indicating ...

How cellular machinery labels proteins for degradation

Proteins are molecular work horses in the cell that perform specific tasks, but it is essential that the timing of protein activities is exquisitely controlled. When proteins have fulfilled their tasks, their degradation ...

Bubble-capturing surface helps get rid of foam

In many industrial processes, such as in bioreactors that produce fuels or pharmaceuticals, foam can get in the way. Frothy bubbles can take up a lot of space, limiting the volume available for making the product and sometimes ...

Astronomers have serious concerns about satellite constellations

Picture the space around Earth filled with tens of thousands of communications satellites. That scenario is slowly coming into being, and it has astronomers concerned. Now, a group of astronomers has written a paper outlining ...

Monitoring organs and cells in living fly larvae

Small changes in a cell's composition can radically transform its function and drive the development of diseases like diabetes, cancer or neuronal dysfunction. Scientists led by the European Molecular Biology Laboratory in ...
