A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks.

While most missions to the moon and other planets rely upon solar power, scientists have assumed that any extended surface mission involving humans would require a more reliable source of energy: nuclear power. Improvements in photovoltaics are upending this calculus. A new study concludes that a solar power system would weigh less than a nuclear system, and would be sufficient to power a colony at sites over nearly half the surface.

Technetium-99m is the world's most commonly used medical radioisotope, but regularly suffers from supply chain shortages, threatening the ability of doctors to diagnose a raft of ailments. But an alternative production technique looks set to make the radioisotope much more easily produced.

Scientists have found a new way to 'see' inside the simplest atomic nuclei to better understand the 'glue' that holds the building blocks of matter together. The results come from collisions of photons (particles of light) with deuterons, the simplest atomic nuclei (made of just one proton bound to one neutron). The photons act somewhat like an x-ray beam to provide the first glimpse of how particles called gluons are arranged within the deuteron.

Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study.

Do two promising structural materials corrode at very high temperatures when in contact with 'liquid metal fuel breeders' in fusion reactors? Researchers now have the answer. This high-temperature compatibility of reactor structural materials with the liquid breeder -- a lining around the reactor core that absorbs and traps the high energy neutrons produced in the plasma inside the reactor -- is key to the success of a fusion reactor design.

To harness the forces that power the Sun, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous soup called plasma. The plasma can rip through any material on Earth, so it must be confined by magnetic fields -- but it can only be controlled for short periods. Now, in a first step to prolonged control, researchers have discovered that the underlying mechanism mirrors the unlikely biological predator-prey model.

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solar astronomy and other fields such as plasma physics, fusion science, and fluid dynamics.

A research team has developed a large-area suspended graphene and irradiated the thinnest graphene target with an ultra-intense laser to realize high-energy ion acceleration. Their findings will be applied to the development of compact, efficient ion accelerators used for cancer treatment, nuclear fusion and so on.
