Praseodymium is a chemical element with the symbol Pr and atomic number 59. It is traditionally considered to be one of the rare-earth metals.
Scandium is a chemical element with the symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element.
Neodymium is a chemical element with the symbol Nd and atomic number 60. It is a rare-earth element. It is a hard, slightly malleable silvery metal that quickly tarnishes in air and moisture.
Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife.
Gadolinium is a chemical element with the symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is only slightly malleable and is a ductile rare-earth element.
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element".
New developments in gene editing reveals that wild plants can be put on the fast track for domestication and the grocery store. Advances in astronomy have captured the inner working of the rare star known as luminous blue variables. Other segments include the use of macrophages to help heal injured muscles and new evidence shows that wildlife is thriving in the suburbs. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.

There’s a factory in Europe that makes antimatter. It’s the rarest, most expensive, and potentially the most dangerous material on Earth. Scientists don’t know why this material is so rare, and its rarity makes it a costly substance. Part of the "Physics Girl" series.
Holmium is a chemical element with the symbol Ho and atomic number 67. It is a rare-earth element.
Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid.
Beryllium is a chemical element with the symbol Be and atomic number 4. It is a relatively rare element in the universe.
Polonium is a chemical element with the symbol Po and atomic number 84. It is a rare and highly radioactive metal with no stable isotopes.
Ruthenium is a chemical element with the symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table.
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.
Palladium is a chemical element with the symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by the English chemist William Hyde Wollaston.
Tungsten, or Wolfram, is a chemical element with the symbol W and atomic number 74. It is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone.
Rhodium is a chemical element with the symbol Rh and atomic number 45. It is an ultra-rare, silvery-white, hard, corrosion-resistant, and chemically inert transition metal. It is a noble metal.
Promethium is a chemical element with the symbol Pm and atomic number 61. All of its isotopes are radioactive; it is extremely rare, with only about 500–600 grams naturally occurring in Earth's crust at any given time.
California’s Pinnacles National Monument is America’s newest National Park. The monument gets its name from its spires and rock formations. It is also home to the California condor, rare chaparral vegetation and carpets of wildflowers.
