The lightest 3D printed padding saddle you can buy? Five cool things coming from Bjorn, Specialized, Campagnolo, Gripgrab and Kostume
I can only apologize for the astronomical prices of some of these products, but they are quite interesting (and ‘cool’ some would say) so take your pick! This week’s highlights include a…
Did supermassive black holes collapse directly from giant gas clouds? It could depend on the magnetic fields
About half a century ago, astronomers realized that the powerful radio source coming from the center of our galaxy (Sagitarrius A*) was a “monstrous” black hole. Since then, they have discovered that…
Astronomers spot the largest potentially dangerous asteroid detected in the last eight years
Twilight observations with the Dark Energy Camera made by the US Department of Energy at NOIRLab’s Cerro Tololo Inter-American Observatory in Chile have allowed astronomers to spot three near-Earth asteroids (NEAs) hidden…

This article by Mariek Schmidt, Associate Professor of Earth Sciences at Brock University, and Chris Herd, Professor of Earth and Atmospheric Sciences at the University of Alberta, originally appeared in The Conversation….
Ancient DNA reveals hidden history of human adaptation
Humans may be just as vulnerable to environmental change as other animals, according to our new research analyzing genetic data from more than a thousand people who have lived in Europe and…
NASA approves Psyche mission to explore ancient planet’s core – IGN
NASA has given the go-ahead for a mission to explore the asteroid Psyche, which could represent the exposed core of a long-dead planet. The mission’s survival had previously been in doubt following…
Breakthrough in optical transmission of information: sound waves traveling in one direction break the reciprocity of light transmission
Scientists at the Max Planck Institute for the Science of Light have succeeded for the first time in creating a unidirectional device that dramatically increases the quality of a special class of…
Researchers determine the three-dimensional structure of PAPP-A
The laminin G (LG)-like domain of the PAPP-A subunit. Representation to emphasize the separation of the CD domain (red, cartoon) and the LG domain (magenta, cartoon) by the M domains (transparent surface)…
Uncover the huge quantum mysteries of black holes
Detector transition probability as a function of √MB/MA . The base of measurement corresponding to the parcel concerned is indicated by the legend. In (a), the dotted lines correspond to √MB/MA=1/n where…
