Hopefully in the future, when somebody tells you they will be making an appointment with a surgeon for an augment, they will come back smarter. The world will be a better place for it.

After a long search, a cosmic mystery has an answer. Astronomers have made the very first unambiguous detection of a radioactive molecule in space — an isotope of aluminium, found in the heart of a rare nova.
Scientists have long been searching for 26 AlF — or Aluminium monofluoride — containing 26 Al, but a direct observation has been exceptionally illusive.
We’ve known about the presence of 26 Al in space for decades. In 1984, NASA’s HEAO 3 satellite data was used to identify gamma-ray radiation originating from the beta decay of the isotope. According to these observations, there’s roughly two solar masses of 26 Al in the Milky Way.

These cells pack together tightly. To accommodate the curving that occurs during embryonic development, it has been assumed that epithelial cells adopt either columnar or bottle-like shapes.
However, a group of scientists dug deeper into this phenomenon and discovered a new geometric shape in the process.
They uncovered that, during tissue bending, epithelial cells adopt a previously undescribed shape that enables the cells to minimize energy use and maximize packing stability. The team’s results will be published in Nature Communications in a paper called “Scutoids are a geometrical solution to three-dimensional packing of epithelia.”
