Nearly two years ago, LIGO opened up a new window onto the cosmos when they discovered gravitational waves. But what has happened since and how could it change our understanding of space, time, and gravity?
Scientists have discovered the fossilised remains of 1.6 billion year-old red algae from India. Advanced multicellular life began much earlier that previously thought and the timing of the tree of life should be revised, they say.
Scientists have developed more than ten different human organ chips, including devices to mimic critical functions of the lungs, kidneys, intestines, liver, and bone marrow. Eventually this technology could render animal testing obsolete.
