Shaping The Culture & Conduct Of Science — Dr. Marcia McNutt Ph.D. — President, National Academy Of Sciences
Dr. Marcia McNutt, Ph.D. is President of the National Academy of Sciences (https://www.nasonline.org/directory-e…), where she also chairs the National Research Council, the operating arm of the National Academies of Sciences, Engineering, and Medicine, and serves a key role in advising our nation on various important issues pertaining to science, technology, and health.
From 2013 to 2016, Dr. McNutt served as editor-in-chief of the Science journals.
The LUX ZEPLIN (LZ) Dark Matter experiment is a large research effort involving over 200 scientists and engineers at 40 institutions worldwide. Its key objective is to search for weakly interacting massive particles (WIMPs) by analyzing data collected by the LZ detector, situated at the Sanford Underground Research Facility in South Dakota.
The LZ Collaboration recently released the results of the first experimental run of the LZ dark matter experiment. These results, published in Physical Review Letters, set new constraints on the interactions between dark matter and other particles, which could inform future searches for weakly-interacting dark matter candidates.
“There is no reason to believe that dark matter will interact with regular matter in the simplest way, so it is important to consider more complex interactions,” Sam Eriksen, co-author of the paper, told Phys.org.
Collaborative work by amateur and professional astronomers has helped to resolve a long-standing misunderstanding about the composition of Jupiter’s clouds. Instead of being formed of ammonia ice—the conventional view—it now appears they are likely to be composed of ammonium hydrosulfide mixed with smog.
The findings have been published in the Journal of Geophysical Research: Planets.
The new discovery was triggered by amateur astronomer, Dr. Steven Hill, based in Colorado. Recently, he demonstrated that the abundance of ammonia and cloud-top pressure in Jupiter’s atmosphere could be mapped using commercially-available telescopes and a few specially colored filters.
A trio of physicists from the University of Rennes, Aoyama Gakuin University, and the University of Lyon have discovered, through experimentation, that it is friction between fibers that allows knitted fabrics to take on a given form. Jérôme Crassous, Samuel Poincloux, and Audrey Steinberger have attempted to understand the underlying mechanics involved in the forms of knitted garments. Their paper is published in Physical Review Letters.
The research team noted that while many of the factors that are involved in intertwined fabrics have been studied to better understand their characteristics (such as why sweaters keep people warm despite the gaps between stitches), much less is known about the form garments made using such techniques can take.
To learn more, they conducted experiments using a nylon yarn and a well-known Jersey knit stitch called the stockinette—a technique that involves forming interlocked loops using knitting needles. They knitted a piece of fabric using 70×70 stitches and attached it to a biaxial tensile machine.
With so much fascinating research going on in quantum science and technology, it’s hard to pick just a handful of highlights. Fun, but hard. Research on entanglement-based imaging and quantum error correction both appear in Physics World’s list of 2024’s top 10 breakthroughs, but beyond that, here are a few other achievements worth remembering as we head into 2025 – the International Year of Quantum Science and Technology.
Quantum sensing
In July, physicists at Germany’s Forschungszentrum Jülich and Korea’s IBS Center for Quantum Nanoscience (QNS) reported that they had fabricated a quantum sensor that can detect the electric and magnetic fields of individual atoms. The sensor consists of a molecule containing an unpaired electron (a molecular spin) that the physicists attached to the tip of a scanning-tunnelling microscope. They then used it to measure the magnetic and electric dipole fields emanating from a single iron atom and a silver dimer on a gold substrate.
Science has been exceedingly successful. But can we account for the success and objects of science without Platonism? Dr. Scott Berman, author of “Platonism and the Objects of Science” (2020), doesn’t think so. (Enjoy the bonus soccer, too!)

Botanists discovered a new lipstick vine species, Aeschynanthus pentatrichomatus, in the Philippine rainforest. Found during a 2022 expedition, the plant is critically endangered and underscores the need for conservation in biodiversity hotspots.
Scientists have announced the discovery of a previously unknown species of lipstick vine, uncovered in the depths of the Philippine rainforest. The groundbreaking findings were published in the Nordic Journal of Botany.
A team of botanists from Oxford University and the University of the Philippines Los Baños made the discovery during a 2022 expedition to the remote Barangay Balbalasang rainforest on Luzon Island. Accessing this nearly impenetrable wilderness required several days of travel and the use of machetes to clear a path. During their exploration, the team was hosted by the Banao Tribe, an indigenous community who protect their local forest.
