The AMS is pleased to announce that Scott Hershberger has been chosen as the 2020 AMS Mass Media Fellow. Scott studied mathematics and physics at Washington University in St. Louis and will graduate in May 2020. He will be working at Scientific American this summer.

The Mass Media Science and Engineering Fellows program is organized by the American Association for the Advancement of Science (AAAS). This program is designed to improve public understanding of science and technology by placing advanced undergraduate, graduate and postgraduate science, mathematics and engineering students in media outlets nationwide. The fellows work for ten weeks over the summer as reporters, researchers, and production assistants alongside media professionals to sharpen their communication skills and increase their understanding of the editorial process by which events and ideas become news.

Now in its 45th year, this fellowship program has placed more than 700 fellows in media organizations nationwide as they research, write, and report today’s headlines. The program is designed to report science-related issues in the media in easy-to-understand ways so as to improve public understanding and appreciation for science and technology.

In response to current challenges that colleges and universities face as a result of the spread of COVID-19, the American Mathematical Society is offering libraries and institutions additional support, in line with recommendations in the ICOLC Statement on the Global COVID-19 Pandemic and Its Impact on Library Services and Resources.

The AMS is also participating in the Copyright Clearance Center Education Continuity License program, providing access to our content for distance learning and other educational uses at no cost to the user.

We are extending grace access for content hosted on our platforms (including MathSciNet) through the end of May for our existing customers. We will re-evaluate this timing as needed.

As courses transition to online, we can provide instructors with complimentary electronic “reserve” copies of our textbooks for cases in which students do not have access to their print copies.

E-books purchased through the perpetual access model on the AMS platform are always available DRM-free with unlimited simultaneous use. In addition, we are partnering with ProQuest to allow multi-user access through mid-June to all e-books purchased on their platforms. Read ProQuest’s statement.

We are providing remote access to all our content, including MathSciNet. In normal circumstances, this remote access can be set up while on campus or while connected via institution VPN (in order to validate IP-based access). We realize many students, faculty, and researchers did not have an opportunity to initiate this access before leaving campus, so we have given instructions to our library partners on how patrons can connect to our content. Please contact your librarian for assistance.

Libraries: if you have not received instructions to share with your patrons, please email us at cust-serv@ams.org or be in touch about any other of your library’s needs.

"Driverless cars, robot butlers and reusable rockets--if the big inventions of the past decade and the artificial intelligence developed to create them have taught us anything, it's that maths is undeniably cool. And if you’re still not convinced, chances are you’ve never had it explained to you via a live experiment with a pigeon before. Temporary pigeon handler and queen of making numbers fun is Dr Hannah Fry, the host of this year's annual Royal Institution Christmas Lectures."

Congratulations to the 2020 AMS Math Poetry Contest Winners in the middle school, high school, and college categories: Sabrina Little, Mackintosh Academy, Boulder, for "Outlier;" Austen Mazenko, Cherry Creek High School, for "The Number Won; and Chenyu Lin, Colorado Christian University, for "x² + y² = 1(ife)." The poems were read during Mathemati-Con at the 2020 Joint Mathematics Meetings in Denver, CO. Read the poems and learn about the contest and Math and Poetry.

Cytochrome c oxidase (CcO) reduces O2 to water, coupled with a proton-pumping process. The structure of the O2-reduction site of CcO contains two reducing equivalents, Fea32+ and CuB1+, and suggests that a peroxide-bound state (Fea33+–O−–O−–CuB2+) rather than an O2-bound state (Fea32+–O2) is the initial catalytic intermediate. Unexpectedly, however, resonance Raman spectroscopy results have shown that the initial intermediate is Fea32+–O2, whereas Fea33+–O−–O−–CuB2+ is undetectable. Based on X-ray structures of static noncatalytic CcO forms and mutation analyses for bovine CcO, a proton-pumping mechanism has been proposed. It involves a proton-conducting pathway (the H-pathway) comprising a tandem hydrogen-bond network and a water channel located between the N- and P-side surfaces. However, a system for unidirectional proton-transport has not been experimentally identified. Here, an essentially identical X-ray structure for the two catalytic intermediates (P and F) of bovine CcO was determined at 1.8 Å resolution. A 1.70 Å Fe–O distance of the ferryl center could best be described as Fea34+ = O2−, not as Fea34+–OH−. The distance suggests an ∼800-cm−1 Raman stretching band. We found an interstitial water molecule that could trigger a rapid proton-coupled electron transfer from tyrosine-OH to the slowly forming Fea33+–O−–O−–CuB2+ state, preventing its detection, consistent with the unexpected Raman results. The H-pathway structures of both intermediates indicated that during proton-pumping from the hydrogen-bond network to the P-side, a transmembrane helix closes the water channel connecting the N-side with the hydrogen-bond network, facilitating unidirectional proton-pumping during the P-to-F transition.

(Carnegie Mellon University) Intelligent tutoring systems have been shown to be effective in helping to teach certain subjects, such as algebra or grammar, but creating these computerized systems is difficult and laborious. Now, researchers at Carnegie Mellon University have shown they can rapidly build them by, in effect, teaching the computer to teach.

Every summer, rainstorms occur in Hong Kong occasionally, leading to loss of property or even casualties.

(Carnegie Mellon University) A new study developed a model of regulation in which the probability of a stricter standard being enacted increased with the proportion of firms in an industry that could meet the standard. The study found that regulations that consider the proportion of firms that can meet the new standard can motivate the development of a new green technology more effectively than regulations that do not consider this factor.
