Fruit flies: Summer pests or scientific marvel?

Fly-swatting season is here. No sooner will you place your fresh strawberries on the kitchen counter than will the first fruit fly arrive. It won't take long for a platoon of Drosophila buddies to be hovering about the spoils.

How variability shapes learning and generalization

Variability is crucially important for learning new skills. Consider learning how to serve in tennis. Should you always practice serving from the exact same location on the court, aiming at exactly the same spot? Although ...

Scientists invent topological-cavity surface-emitting laser

Semiconductor lasers are the most widely used lasers due to their compact size, high efficiency, low cost and wide spectra. But they suffer low output power and low beam quality—two specifications difficult to improve simultaneously. ...

Using electrons to accelerate molecular recognition

A team of researchers affiliated with multiple institutions in the U.S. and China and one in Australia has developed a way to use electrons to accelerate molecular recognition. In their paper published in the journal Nature, ...

How bacteria cope with stress

When exposed to stress, bacteria allow their metabolism to take a break during which they suppress, for example, the incorporation of proteins into membranes. Scientists from Marburg, Freiburg and Munich have discovered this ...

Scientists demonstrate self-awareness in fish

Mirror self-recognition (MSR) is seen as evidence for self-awareness and passing the mark test, in which animals touch or scrape a mark placed on their body in a location that can only be indirectly viewed in a mirror, is ...
