Never too local for science advice
No government is too small to promote data-informed decisions and innovation. This is especially true for cities, argues Rémi Quirion.

Video: The Leslie Science & Nature Center visits AAPS’ Summer Learning Institute
The Leslie Science & Nature Center brought nature to life Monday at the AAPS Summer Learning Institute. Students got to see a live hawk up close and learn about these birds of prey. Staff also shared fascinating facts about trees and their importance in our ecosystem during a “Build a Tree” exercise where kids acted…

Computational electrochemistry of oxygen 150 years after Priestley
Since the first isolation of oxygen, chemists have explored oxygen reduction and evolution reactions. Now, computational chemists are trying to understand and predict the best catalysts for them. Here, the importance of various considerations for such calculations, as well as their challenges and opportunities, are discussed. This is a preview of subscription content, access via…

AI is complicating plagiarism. How should scientists respond?
From accusations that led Harvard University’s president to resign in January, to revelations in February of plagiarized text in peer-review reports, the academic world has been roiled by cases of plagiarism this year. But a bigger problem looms in scholarly writing. The rapid uptake of generative artificial intelligence (AI) tools — which create text in…

How to spot a predatory conference, and what science needs to do about them: a guide
Last year, Kutubuddin Molla disappointed a postdoctoral colleague who had sought his advice about a conference in Italy. “I quickly recognized it as predatory. They invited him as a keynote speaker, despite him not having any publications in that field yet,” Molla says. Like his colleague and many other scientists, Molla, a plant geneticist at…

Guidelines on lab-grown embryo models are strong enough to meet ethical standards — and will build trust in science
In July, researchers in the United Kingdom published a code of practice on how human stem cells should be used to mimic embryo development in the laboratory. This code was produced by a working committee of 13 developmental biologists, stem-cell scientists, legal scholars, regulatory specialists and bioethicists, of which I was chair. It is the…

Sexual harassment in science: biologists in India speak out
It seemed like the opportunity of a lifetime for AM, a young Indian graduate student who loved studying reptiles. In December 2015, she began fieldwork for her master’s thesis at a non-profit organization’s turtle conservation programme. That New Year’s Eve, the 21-year-old student attended a party with her colleagues at her male supervisor’s house. At…
