Electrical fields can throw a curveball

Electrical fields can throw a curveball

Researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately lead to new ways of performing certain industrial or medical processes that require separation of tiny suspended materials. …read more

Novel insight reveals topological tangle in unexpected corner of the universe

In a recent theoretical study, scientists discovered the presence of the Hopfion topological structure in nano-sized particles of ferroelectrics — materials with promising applications in microelectronics and information technology. …read more

A clue as to why it’s so hard to wake up on a cold winter’s morning

A clue as to why it’s so hard to wake up on a cold winter’s morning

Do you remember the challenge of waking up on winter’s cold, dark days? Neurobiologists have uncovered a clue to what’s behind this behavior. In a study of the fruit fly, the researchers have identified a ‘thermometer’ circuit that relays information about external cold temperature from the fly antenna to the higher brain. They show how, through this circuit, seasonally cold and dark conditions can inhibit neurons within the fly brain that promote activity and wakefulness, particularly in the morning. …read more

Mississippi Delta marshes in a state of irreversible collapse

Mississippi Delta marshes in a state of irreversible collapse

A key finding of the study is that coastal marshes experience tipping points, where a small increase in the rate of sea-level rise leads to widespread submergence. …read more

A stitch in time: How a quantum physicist invented new code from old tricks

A stitch in time: How a quantum physicist invented new code from old tricks

Building large-scale quantum computers will require suppression of errors. Scientists have used a neat trick to apply powerful 3D error-suppression codes in a 2D architecture, something one industry insider said many thought was impossible. …read more

Preventing ‘cytokine storm’ may ease severe COVID-19 symptoms

A clinical trial in people with the new coronavirus is testing a drug that may halt an overactive immune response before it ramps up. …read more

Capturing the coordinated dance between electrons and nuclei in a light-excited molecule

Capturing the coordinated dance between electrons and nuclei in a light-excited molecule

Using SLAC’s high-speed ‘electron camera,’ scientists simultaneously captured the movements of electrons and nuclei in a light-excited molecule. This marks the first time this has been done with ultrafast electron diffraction, which scatters a powerful beam of electrons off materials to pick up tiny molecular motions. …read more
