A New Discovery Just Made Science Textbooks around the World Dated
Scientists confirmed the discovery of four new elements.
Science textbooks, charts, and other mentions of the periodic table just became out of date. The International Union of Pure and Applied Chemistry has verified the discovery of four super-heavy elements, completing the seventh row of the periodic table. It's an exciting day for chemists.
The new elements were discovered by teams of scientists from Russia, Japan, and America. These will be the first elements added since 114 (Flerovium) and 116 (Livermorium) were added to the table in 2011.
The trick to “finding” these elements isn't so much in searching for them as it is in creating them. The new elements, given the atomic numbers 113, 115, 117, and 118 are synthetic — they do no occur naturally. Their origins lie in slamming lighter nuclei into each other and hoping something fuses together.
Many super-heavy elements that populate the periodic table come into existence for microseconds in laboratory conditions.
Professor Paul Karol said, "A particular difficulty in establishing these new elements is that they decay into hitherto unknown isotopes of slightly lighter elements that also need to be unequivocally identified, but in the future we hope to improve methods that can directly measure the atomic number, Z."
Many super-heavy elements that populate the periodic table come into existence for microseconds in laboratory conditions. The proof of their existence lies in detecting the properties in the radioactive decay chains.
Eventually, the laws of physics may halt the progression of creating new elements. But for now, there are four new elements that need proper names. The IUPAC will formally announce the finalized names this summer. “New elements can be named after a mythological concept, a mineral, a place or country, a property, or a scientist,” the IUPAC wrote in a press release.
Hopefully the IUPAC will have a little fun naming the new elements and interest the public in what is some pretty amazing science. It couldn't hurt our efforts to make science fascinating to young people, explains theoretical physicist and string theorist Brian Greene.

It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
It's not just a case of "what doesn't kill you makes you stronger."
- A new study suggests children who endure trauma grow up to be adults with more empathy than others.
- The effect is not universal, however. Only one kind of empathy was greatly effected.
- The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.
