Shaking Schrödinger’s cat

Shaking Schrödinger’s cat

Frequent measurement of a quantum system’s state can either speed or delay its collapse, effects called the quantum Zeno and quantum anti-Zeno effect. But so too can “quasimeasurements” that only poke the system and garner no information about its state.
Bacteria that Eat Electricity

Bacteria that Eat Electricity

Just when we thought we knew it all, scientists have discovered that there are microbes that eat electricity, which is about as strange as people snacking by shoving a finger in an electric socket. What’s more, these microbes are very common. Scientists are finding them in many different places. They’ve remained hidden so long because […]

A ring to bind them

Using genomics, a chemistry lab has worked out the biosynthetic machinery that makes a new class of antibiotic compounds called the beta-lactones. Like the beta-lactams, such as penicillin, they have an unstable four-member ring. The key to their antibiotic activity, it is also difficult to synthesize.
Death by volcano?

Death by volcano?

The discovery of anomalously high levels of mercury in rocks from the Ordivician geological period has led to a new interpretation of the ensuing mass extinction. A sequence of disturbances may have led to catastrophic cooling by reflective sulfate aerosols injected into the atmosphere by massive volcanism. The finding is important since aerosol cooling is under consideration as a way to temper global warming.
New use for a pesky weed

New use for a pesky weed

Dandelions are much-maligned weeds, with a paratrooper-like seed dispersal system that makes them difficult to eradicate. However, new research from an engineer at Washington University in St. Louis finds a great benefit in an unlikely place for the pesky dandelion: each of its tiny seeds can be used as a perfect pipette in the laboratory setting.
