Domesticated rice has fatter seed grains with higher starch content than its wild rice relatives — the result of many generations of preferential seed sorting and sowing. But even though rice was the first crop to be fully sequenced, scientists have only documented a few of the genetic changes that made rice into a staple food for more than half the world’s population.

The 20th year of particle collisions is underway at the Relativistic Heavy Ion Collider (RHIC), a U.S. Department of Energy Office of Science user facility for nuclear physics research at Brookhaven National Laboratory. The particle smashups will continue over a range of collision energies through the first half of 2020, with members of RHIC's STAR collaboration collecting data from millions of collisions that take place at the center of their house-sized particle detector.

Scientists may have figured out how dust particles can stick together to form planets, according to a Rutgers co-authored study that may also help to improve industrial processes. In homes, adhesion on contact can cause fine particles to form dust bunnies. Similarly in outer space, adhesion causes dust particles to stick together. Large particles, however, can combine due to gravity – an essential process in forming asteroids and planets. But between these two extremes, how aggregates grow has largely been a mystery until now.

Scientists at Johns Hopkins Medicine report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size — even hefty ones attached to the gene-editing tool called CRISPR. If their creation – constructed of a biodegradable polymer — passes more laboratory testing, it could offer a way to efficiently ferry larger medical compounds into specifically selected target cells.

A Queen’s University Belfast scientist has led an international team to the ground-breaking discovery of why the Sun’s magnetic waves strengthen and grow as they emerge from its surface, which could help to solve the mystery of how the corona of the Sun maintains its multi-million degree temperatures. For more than 60 years observations of the Sun have shown that as the magnetic waves leave the interior of the Sun they grow in strength but until now there has been no solid observational evidence as to why this was the case.
