Global quantum communications -- no longer the stuff of fiction?

Global quantum communications -- no longer the stuff of fiction?

Neither quantum computers nor quantum cryptography will become prevalent technologies without memory systems able to manipulate quantum information easily and effectively. The Faculty of Physics at the University of Warsaw has recently made inroads into popularizing quantum information technologies by creating an atomic memory with outstanding parameters and an extremely simple construction.

First harvest of research based on the final GOCE gravity model

First harvest of research based on the final GOCE gravity model

Just four months after the final data package from the GOCE satellite mission was delivered, researchers are laying out a rich harvest of scientific results, with the promise of more to come. A mission of the European Space Agency (ESA), the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) provided the most accurate measurements yet of Earth's gravitational field. The GOCE Gravity Consortium, coordinated by the Technische Universität München (TUM), produced all of the mission's data products including the fifth and final GOCE gravity model.

An eel-lectrifying future for autonomous underwater robots

On 24 October 2014, Sweden called off the hunt for a submarine after a week-long underwater search in the Stockholm archipelago. Triggered by a reported sighting of a Russian submarine, the alleged 'invasion' had been widely anticipated by military specialists and the media.

"Our assessment is that in the inner archipelago there was a plausible foreign underwater operation," Rear Adm. Anders Grenstad commented, "But we believe that what has violated Swedish waters has left."

Protecting the rainforest through agriculture and forestry

Protecting the rainforest through agriculture and forestry

Conservationists are always looking for ways to halt the pace of deforestation in tropical rainforests. One approach involves recultivating abandoned agricultural land. An international team* investigating this concept has just published its findings in Nature Communications. Working in the mountainous regions of Ecuador, the researchers found afforestation and intense pasturing to be particularly effective, clearly increasing the environmental and economic value of abandoned farmlands.

A drunken sailor staggers onto a square with lots of streetlamps on it. Sometimes he will run into one of the lamps, change his direction and keep moving. Does the time he spends on this square depend on the number of streetlamps? The surprising answer is: no.

Toolkit for ocean health

The ocean is undergoing global changes at a remarkable pace and we must change with it to attain our best possible future ocean, warns the head of The University of Western Australia's Oceans Institute.

One of the global leaders in ocean science, Professor Carlos Duarte has shared his insights on the future of the world's oceans in a paper published in the international open-access journal Frontiers in Marine Science.

In the paper Professor Duarte explains the grand challenge researchers face in addressing global change and the future state of the ocean.

How various brain areas interact in decisions

The value of a piece of chocolate cake can change. Someone who happens to be on a diet is more likely to choose a fruit dessert and judge the calorie-laden cake as unhealthy. Previous studies have shown that a specific network in the brain is active when a person must decide between various choices that vary depending on context. They emphasize the interaction between neurons in two brain areas of the prefrontal cortex - the controlling area on the front side of the brain.
