The Cronica universalis, written in Latin by the Milanese friar Galvaneus Flamma (in Italian, Galvano Fiamma, 1283 – c. 1345), contains an astonishing reference to a land named Marckalada (terra que dicitur Marckalada), situated west from Greenland. This land is recognizable as the Markland mentioned by some Icelandic sources and …

For years, the conventional wisdom has been that you can’t just nuke an incoming asteroid to save the planet, no matter what Hollywood movies have told you. The logic is quite straightforward; blowing space rocks into pieces would cause an even deadlier rain of smaller astroids that would pelt the …

To answer the big questions, sometimes we must look to the very small. Researchers at the Los Alamos Neutron Science Center’s Ultracold Neutron Source, within Los Alamos National Lab, have been passing the cryo-baton for more than a decade, working at ever colder temperatures in order to study the behavior …

Having spent time in the trenches with many startups, I’ve been lucky to see why many growth marketing engines don’t work correctly. I say I’m lucky because the issues I’ve seen have taught me an immense amount about what makes a well-oiled, polished growth marketing engine fire on all cylinders. …

Planetary scientists have analyzed images taken by the Mastcam-Z camera and the Remote Micro-Imager of the SuperCam instrument on NASA’s Perseverance rover — which landed in Jezero crater in February 2021 — in the three months after landing. The images show the geologic layers of an ancient river delta, which …

Fenchol, a natural compound commonly present in some plants including basil (Ocimum basilicum), decreases Alzheimer’s disease pathology by activating the free fatty acid receptor 2 (FFAR2) signaling, according to new research published in the journal Frontiers in Aging Neuroscience. Fenchol, a plant-derived compound that gives basil its aromatic scent, can …

Photo: Mike MacKenzie, FlickrAs Moore’s Law approaches its endgame, the technosphere has looked to different and more diverse approaches to computing. In order to continue to increase the computational power of our systems, we can’t just depend on driving clock speeds higher and higher, nor can we continue making transistors …

NASA and Boeing have provided an update on the status of the Starliner spacecraft, which has been on the verge of launching several times now. The vessel was supposed to head off to the International Space Station (ISS) in August, but a last-minute issue with the craft’s fuel valves caused …
