A revolution in knot theory
In the 19th century, Lord Kelvin made the inspired guess that elements are knots in the "ether". Hydrogen would be one kind of knot, oxygen a different kind of knot---and so forth throughout the periodic table ...
Researchers discover material with graphene-like properties
After the Nobel Prize in Physics was awarded to two scientists in 2010 who had studied the material graphene, this substance has received a lot of attention.
IUPAC votes to change standard atomic weights of 19 elements
German team finds a way to link boron atoms with a triple bond
Modern-day alchemy: A recipe for a new superheavy element
Even though nearly 80 years have passed since the discovery of Technetium, the first "synthetic" element, the periodic table of elements remains a work in progress.
New physics in a copper-iridium compound
(Phys.org) —An unexpected magnetic behavior within Sr3CuIrO6, a transition-metal compound (TMC) that combines the transition metal copper with the transition metal iridium has been revealed by research ...
Using the world's rarest element to study the world's rarest force
In September 2012 an experiment at the TRIUMF accelerator complex reached a milestone. The FrPNC collaboration —-short hand for Francium Parity Non-conservation—-succeeded in trapping several kinds of ...
Scientists theorize properties of fleeting astatine
Astatine is among the world's rarest elements – with a maximum half-life of just eight hours, found in tiny amounts in natural radioactive decay chains, but also produced by bombarding bismuth with energetic ...
The changing shape of an atomic nucleus
The nucleus of an atom can have different shapes that co-exist. European scientists investigated nuclear shape change with advanced experimental techniques.
On early Earth, iron may have performed magnesium's RNA folding job
On the periodic table of the elements, iron and magnesium are far apart. But new evidence suggests that 3 billion years ago, iron did the chemical work now done by magnesium in helping RNA fold and function ...
QR code access to Nobel Prizes in Chemistry
Mobile devices equipped with a QR (quick response) code scanning app, which gives consumers instant access to information on the Web, now can give the same access to 110 years of information about the most ...
Suzaku spies treasure trove of intergalactic metal
Every cook knows the ingredients for making bread: flour, water, yeast, and time. But what chemical elements are in the recipe of our universe?
