A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). Such experiments demonstrate the secure satellite-to-ground exchange of cryptographic keys during the passage of the satellite Micius over a ground station. Using Micius as a trusted relay, a secret key was created between China and Europe at locations separated up to 7,600 km on the Earth.

Increased levels of one protein in old blood may contribute to its aging effects on the brain, a mouse study suggests.
In an advance that could push cheap, ubiquitous solar power closer to reality, University of Michigan researchers have found a way to coax electrons to travel much further than was previously thought possible in the materials often used for organic solar cells and other organic semiconductors.

The unlikely friendship that allowed an untrained Indian mathematician to become an acclaimed academic.
All animals capable of regenerating a lost body part, from an organ or a limb to the whole organism, use a common set of genes. This is the striking discovery of a team of researchers from the Center for Complexity and Biosystems of the University of Milan, led by Caterina La Porta. They analyzed the genetic activity in regenerating tissues from widely different speciesâfrom hydra to mice. They found that some of the genes active at the beginning of the regeneration process are the same in very different species, including mammals which have lost this function during evolution, except for the restoration of the liver. The discovery of this shared genetic signature is of great importance to understand how regeneration evolved and could be useful for future regeneration therapies.

Relativity says we live in four dimensions. String theory says it’s 10. What are ‘dimensions’ and how do they affect reality?
2018 will be another year in which the Internet of Things (IoT) will be massive. Here we look at the key IoT predictions from the IBM Watson IoT team, which include the rise of artificial intelligence in IoT, edge computing and more.

The National Weather Service says that the most likely explanation for an object which sent out illumination and a sonic boom throughout southwest Michigan, five other states, and Canada on Tuesday night was the breakup of a meteor, WXYZ reported. The American Meteor Society collected at least 200 reports of the incident, which for around a second was so bright it lit parts of the Detroit region like it was daytime.

Creativity is often defined as the ability to come up with new and useful ideas. Like intelligence, it can be considered a trait that everyone – not just creative “geniuses” like Picasso and Steve Jobs – possesses in some capacity.
One of the most important and fraught processes in the human body is inflammation. Inflammatory responses to injury or disease are crucial for recruiting the immune system to help the body heal, but inflammation can also cause an increase in the production of thrombin, which can lead to dangerous blood clots and other conditions. Activated protein C (APC) is a naturally occurring anti-coagulant protein with anti-inflammatory and other protective effects that has been used medically to treat severe blood infections and wounds; however, its use is limited because its inhibition of thrombin also impacts the blood’s ability to clot, increasing bleeding risk.
