Zero-emissions long-distance aviation is absolutely possible… Provided you’re not in a hurry. Solar Airship One will take 20 days to fly all the way around the equator, some 40,000 km (~25,000 miles), in a single zero-emissions hop.
The 151-m (495-ft)-long airship will have its entire upper surface covered in solar film – some 4,800 square meters (51,700 sq ft) of it, or about nine-tenths of an NFL football field for those of you who prefer the standard units.
By day, the solar panels will run the airship’s electric propulsion systems, while also banking up extra power for the overnight haul by electrolyzing water into hydrogen. By night, the hydrogen will run through a fuel cell, providing the juice to keep going.
When learning, patients with schizophrenia or depression have difficulty making optimal use of information that is new to them. In the learning process, both groups of patients give greater weight to less important information and, as a result, make less than ideal decisions.
This was the finding of a several-months-long study conducted by a team led by neuroscientist Professor Dr. med. Markus Ullsperger from the Institute of Psychology at Otto von Guericke University Magdeburg in collaboration with colleagues from the University Clinic for Psychiatry & Psychotherapy and the German Center for Mental Health.
By using electroencephalography (EEG) and complex mathematical computer modeling, the team of researchers discovered that learning deficits in depressive and schizophrenic patients are caused by diminished/reduced flexibility in the use of new information.
Those hoping to avoid one of the worst side effects of aging—bone, joint and muscle pain that doesn’t go away—might need to exercise a lot harder and more often than previously believed.
According to a new study, only high levels of activity at least once a week—playing tennis, running, swimming, digging with a spade, or doing hard physical labor as part of your job—appears to help ward off chronic musculoskeletal pain in the long-term.
The study, led by Dr. Nils Niederstrasser at the University of Portsmouth, examined the data of 5,802 people aged 50 or more over ten years.
There is a neurological link between serotonin levels and the brain’s ability to control impulses and patience levels.
A secure exchange between a merchant and a buyer has been successfully tested as a proof of concept using a small quantum computing network in China.
A 26-year-old man with a 1-week history of a rash on his hands and feet and fever had scattered, partially blanchable macules that had merged into erythematous patches on his hands and feet. Read the full clinical case from มหาวิทยาลัยเชียงใหม่ Chiang Mai University:

Solar panels are already an affordable energy solution since they generate enough power over their lifetimes to pay for themselves and then some. However, they do take some investment up front, and some people (and homeowners associations) dislike the way they look.
So what if you could get that power to make electricity from sunlight without having to install solar panels? That’s the beauty of solar paint, as reported by Solar Action Alliance.
The idea behind solar paint (aka photovoltaic paint) is simple: It’d be like ordinary paint but with billions of light-sensitive particles mixed in, as Understand Solar notes.
For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?
Many organisms can produce minerals or mineralized tissue. A well-known example is nacre, which is used in jewelry because of its iridescent colors. Chemically speaking, its formation begins with a mollusk extracting calcium and carbonate ions from water. However, the exact processes and conditions that lead to nacre, a composite of biopolymers and platelets of crystalline calcium carbonate, are the subject of intense debate among experts, and different theories exist.
Researchers do agree that non-crystalline intermediates, such as amorphous calcium carbonate (ACC), play a crucial role in biomineralization. Lobsters and other crustaceans, for example, keep a supply of ACC in their stomachs, which they use to build a new shell after molting. In a recent study published in Nature Communications, researchers from the University of Konstanz and Leibniz University Hannover have now succeeded in deciphering the formation pathway of ACC.
