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.

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
