There's a Massive Hidden Factor in The Evolution of Humans Over 2 Million Years
The course of human evolution over the last 2 million years was shaped by habitation shifts linked to astronomically driven climate change, scientists suggest in a new study.

The first vertical test shot of Green Launch's hydrogen-powered impulse launch cannon.
The hydrogen cannon can be fired every 60-90 minutes, sending its hypersonic projectile skyward where it'll "penetrate the atmosphere within a minute and shed its aeroshell." Low earth orbits between 300-1,000 km (186-621 miles) can be achieved in under two hours, and some much quicker.

Electric chopsticks that make low-salt food taste salty developed by Meiji University
One of the big drags of getting older is not being able to eat with abandon any more. Nowadays just looking at the amount of salt my kids pour onto their food is enough to give me heart palpitations, but it sure would be nice to indulge in those strong flavors without risking a lifestyle disease.
Food producer Kirin and Meiji University seem to agree and through extensive research have developed a pair of chopsticks that can stimulate the taste of salt in foods with low salt content. This still unnamed device does this simply by sending a weak electric current right into your food.

Scientists have created new artificial microbes by combining two very different organisms into one functioning entity. The hybrid of a yeast and a bacterium adds evidence to a long-standing hypothesis on how advanced life may have evolved.
Inside the cells of complex lifeforms are tiny, separate organs called organelles, some of which have their own separate genomes to that of the larger organism. That includes the mitochondria in animals and chloroplasts in plants, both of which generate energy for the organism. A leading theory suggests that these organelles were originally separate microorganisms that were engulfed by other cells, and the two eventually entered a symbiotic relationship that paved the way for complex life to evolve.
And now a new study has recreated this process, known as endosymbiosis. Researchers from the University of Illinois Urbana-Champaign designed and engineered artificial hybrids of two microbes – a budding yeast and photosynthetic cyanobacteria.
The resulting chimera was able to photosynthesize like the bacteria to generate energy, and reproduced through budding like the yeast. The organisms were able to propagate for at least 15 to 20 generations, and the team says that the achievement lends weight to the hypothesis that complex life got its start through endosymbiosis.
