Acta Pharmaceutica Sinica B volume 15, Issue 3 publishes

Compuscript Ltd
Peer-Reviewed Publication

https://www.sciencedirect.com/journal/acta-pharmaceutica-sinica-b/vol/15/issue/3

Acta Pharmaceutica Sinica B (APSB) was founded with the goal of creating a global high-level forum centred around drug discovery and pharmaceutical research/application. APSB was included by Chemical Abstracts in 2011, accepted by PubMed Central in 2015, indexed by Science Citation Index in 2017 and has evolved to become one of the most important international journals in the field of pharmaceutical sciences.

Light that spirals like a nautilus shell

Harvard John A. Paulson School of Engineering and Applied Sciences
Peer-Reviewed Publication

Pushing the limits of structured light, Harvard applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create unique patterns. The way the light behaves resembles spiral shapes common in nature.

For a better cup of coffee, look to physics

University of Pennsylvania
Peer-Reviewed Publication

In the Arnold Mathijssen Lab at the Univeristy of Pennsylvania, researchers used a gooseneck kettle, coffee grinder, and a pour-over setup alongside precise measurements and high-speed analysis to study the fluid dynamics and mechanics of coffee brewing to uncover ways to maximize flavor with fewer grounds. The findings could help researchers understand fluid dynamics.

Scientists observe exotic quantum phase once thought impossible

Rice University
Peer-Reviewed Publication

A team of Rice researchers reported the first direct observation of a surprising quantum phenomenon predicted over half a century ago known as a superradiant phase transition, which occurs when two groups of quantum particles begin to fluctuate in a coordinated, collective way without any external trigger, forming a new state of matter.

Watch a live catalytic event in real time

Northwestern University
Peer-Reviewed Publication

A Northwestern University-led international team of scientists has, for the first time, directly observed catalysis in-action at the atomic level. In mesmerizing new videos, single atoms move and shake during a chemical reaction that removes hydrogen atoms from an alcohol molecule. By viewing the process in real time, the researchers discovered several short-lived intermediate molecules involved in the reaction as well as a previously hidden reaction pathway.

Hundred-year storm tides will occur every few decades in Bangladesh, scientists report

Massachusetts Institute of Technology
Peer-Reviewed Publication

For the highly populated coastal country of Bangladesh, once-in-a-century storm tides could strike every 10 years — or more often — by the end of the century, scientists report.
