Because of the physical limitations of silicon-based circuitry, there is an upper limit to how powerful a modern computer can be made. In response to this, researchers have been looking into other mediums to build faster and more powerful computers from, including using quantum-based processors, and neurological chips based on human brain cells. Another promising idea, based on DNA, plans to utilize the otherwise naturally-occurring computer of genetics.

Archaeologists have announced the discovery of a 50,000-year-old sewing needle, made from bone, that was excavated from a cave in Siberia’s Altai Mountains. This well-preserved sewing implement sports a hole for guiding the thread, and is still appears to be sharp enough to be used today. This artifact, however, has an unusual distinction, in that it is suspected that it was not crafted by a human hand.

Despite the progress made by modern science over the past few centuries, one of the biggest questions that has been on the mind of man since time immemorial, and yet remaining perhaps the most elusive, is that of the nature of consciousness: we know it exists, but we have no real way to measure, quantify, or even define it. On top of this, science can’t even definitively determine where it comes from, or even why it exists to begin with. And now a prominent physicist, renowned for his work in the field of string theory, feels this scientific mystery may remain permanent.

Astronomers have discovered something strange about an ultra-diffuse galaxy in the Coma Cluster called Dragonfly 44. It went largely overlooked by astronomers until recently, due to it only emitting 1 percent of the light that the Milky Way does, hence its "ultra diffuse" status. But Dragonfly 44 has recently been found to be nearly the same mass as our own galaxy, due to being made nearly entirely of dark matter.
