Doubling down on Schrödinger’s cat
Yale physicists have given Schrödinger’s famous cat a second box to play in, and the result may help further the quest for reliable quantum computing. (more…)

Europaweit kollabieren ganze Bienenvölker. In Deutschland starben in den letzten Jahren jährlich bis zu 30 Prozent der Bienenvölker; und auch weltweit berichten Imkerinnen und Imker von einem plötzlichen Rückgang ihrer Bienenpopulationen. Greenpeace zeigt im neuen Ratgeber „Rettet die Biene“, wie jeder Einzelne zum Bienenschutz beitragen kann.
Das weltweite Bienensterben betrifft uns alle. Ein Drittel unserer Nahrungsmittel gäbe es ohne bestäubende Insekten wie die Bienen nicht. Bienen besuchen viele unterschiedliche Blüten wie Raps, Sojabohnen, Zwiebeln, Gurken, Brokkoli und Sonnenblumen – aber auch Äpfel, Orangen, Blaubeeren, Avocados, Tee und Kaffee. (more…)
Many infections, even those caused by antibiotic-sensitive bacteria, resist treatment. This paradox has vexed physicians for decades, and makes some infections impossible to cure.
A key cause of this resistance is that bacteria become starved for nutrients during infection. Starved bacteria resist killing by nearly every type of antibiotic, even ones they have never been exposed to before. (more…)
In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery, described in the Feb. 3 issue of Science Express, can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams
JILA is jointly operated by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder. (more…)
