First passive recordings from ocean gliders provide insight into whale behavior for some endangered species
Like robots of the deep, autonomous underwater vehicles, or AUVs, are growing in number and use in the oceans to perform scientific missions ranging from monitoring climate change to mapping the deep sea floor and surveying ancient shipwrecks. Another use for these versatile platforms has now been found: monitoring the lives of whales.
Marine mammals are major predators in the ocean, but little is known about many of them and how changing ocean conditions affect their distribution. Traditional ship or aerial surveys rely on human observers to detect marine mammals, but these observations are limited to daylight hours and periods of calm seas and good visibility. As a result, these surveys are time-consuming, inefficient, and expensive. Marine mammals can also be detected by passively listening for their vocalizations. Passive acoustic monitoring of marine mammals is unaffected by weather, but most applications to date have involved moored or fixed recorders that can assess only when marine mammals appear in a single location.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
