Earths oceans are what make this a Blue Planet. Our seas influence the climate, produce most of the oxygen we breathe, serve as a means of transport and a major source of food and resources. Todays World Ocean Day is a chance to learn more about the seas that surround us – and how satellite monitoring helps protect them.
Wednesday 8 June is the 13th annual World Ocean Day. Created in 1992 at the Earth Summit at Rio de Janeiro, World Ocean Day is an opportunity to celebrate our world ocean, its abundant life, and the ways we are all connected to the sea, no matter how far we live from its edge. More than 600 aquariums, zoos, museums and conservation organisations are participating in global activities today.
The ocean is no longer so abundant and clean as it once was: many of the worlds fisheries are in decline, coral ecosystems are deteriorating and fragile coastal habitats being choked by pollution. But today and every day, Earth Observation spacecraft continuously acquire data across the seven tenths of our planet covered by the sea.

DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.
Researchers have created chemical amplifiers and a chemical oscillator using a systematic method that has the potential to embed sophisticated circuit...
MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor...

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
