Phys.org / Ultra-faint galaxy discovered near Andromeda may be 12.5 billion years old
A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the galaxy, named And XXXVI, ...
Phys.org / UV light patterns thermochromic crystals without damage, unlocking color-changing designs
Color-changing mood rings, forehead fever strips and car-shade indicators all change hues as they warm and cool, thanks to a phenomenon called thermochromism. On a smaller scale, thermochromism is used in nanotechnologies ...
Tech Xplore / A diving suit for cyborg cockroaches could enhance search-and-rescue operations
Scientists from NTU Singapore and Waseda University have developed a flexible "diving suit" for cyborg cockroaches, enabling the insects to survive and move underwater and in low-oxygen environments for up to three hours. ...
