The question of how the chemical composition of a protein—the amino acid sequence—determines its 3D structure has been one of the biggest challenges in biophysics for more than half a… Read More »Physicists use AI to find the most complex protein knots so far

Children who suddenly appear to lose the thread of an otherwise obvious conversation often do so because they cannot combine two key communicative skills until surprisingly late in their development,… Read More »Clashes of inference and perspective explain why children sometimes lose the plot in conversation

Highly energetic and difficult to detect, neutrinos travel billions of light years before reaching our planet. Although it is known that these elementary particles come from the depths of our… Read More »Neutrino factories in deep outer space

As our devices become smaller, faster, more energy efficient, and capable of holding larger amounts of data, spintronics may continue that trajectory. Whereas electronics is based on the flow of… Read More »Researchers learn to control electron spin at room temperature to make devices more efficient and faster
