The integration of a chiral halide perovskite semiconductor into a light-emitting diode (LED) structure made from a III–V optoelectronic semiconductor creates a spin-LED that achieves 15% circularly polarized emission at room temperature without a magnetic field — a potential boon for spintronics and other spin‑based technologies.

A gas of molecules that interact over long distances has been cooled to mere nanokelvins, resulting in the emergence of a state known as a Bose–Einstein condensate — the first of its kind in this type of molecular system.

Reactions have been discovered that selectively transform nitrogen-containing rings, called pyrimidines, into various other ring systems — enabling rapid preparation of compound libraries for pharmaceutical research.

The discovery of a rib fragment from Baishiya Karst Cave greatly extends the presence of Denisovan hominins on the Tibetan Plateau. In-depth analyses of fossilized animal bones from the same site show that Denisovans made full use of the available animal resources.
