Speedy nuclei do the twist
DOE/US Department of Energy
The way hydrocarbon molecules interact with light can affect the production of nitrous acid in the atmosphere. In this study, researchers used an ultrafast electron camera to image the motions of hydrocarbon molecules at ultrafast, ultrasmall scales. They identified a proton transfer step followed by an out-of-plane twisting motion as key components of energy relaxation after molecules interact with light.

Republicans respond to political polarization by spreading misinformation, Democrats don't
American Marketing AssociationAlthough Republicans may understand the misinformation content is very likely false, they are willing to spread it to help their party gain an advantage over the opposition.

Informaticians apply tools and techniques to eliminate ambiguity and better implement guidelines and policies in pediatric care
Regenstrief Institute
In “Better Guidelines and Policies: AAP’s Partnership for Policy Implementation,” published in the journal Pediatrics, the authors write that with the increasing use of electronic health records (EHRs) in pediatrics, medical societies need to eliminate ambiguity in their guidelines to standardize care delivery, improve care quality and patient outcomes and reduce variation and costs. "Informaticians are ideally suited to help with the implementation and the clarity that guidelines need to be implemented or incorporated into EHRs that are widely prevalent in our healthcare systems," said Regenstrief Institute Research Scientist Randall Grout, M.D., M.S. Dr. Grout is also the chief health informatics officer at Eskenazi Health and an assistant professor of pediatrics at the Indiana University School of Medicine.

Stormy findings and hot discoveries
Weizmann Institute of Science
The summer of 2024 was the hottest on record, driven by weakening air circulation systems that disperse heat and moisture globally. Two studies led by Dr. Rei Chemke of the Weizmann Institute of Science reveal that human activities, particularly greenhouse gas emissions, are causing this weakening.

Into the light
Weizmann Institute of Science
In photosynthesis, harnessing the power of the Sun is made possible by the flow of electrons from one protein to another inside an organelle called the chloroplast. This organelle contains a complex system of membranes, some of which are densely stacked, and others that are organized into more expansive assemblies. Until now, the scientific consensus was that this spatial structure forces the electrons to cover large distances between proteins, slowing down the process of photosynthesis. But in a paper recently published in Nature Plants, a research team led by staff scientist Dr. Reinat Nevo from Reich’s lab revealed that the membranes change their organization in space during the transition from darkness to light, enabling the proteins to come closer to one another and thus shortening the distance the electrons must cross.

Robots give scientists unprecedented access to study coral reef biodiversity
Okinawa Institute of Science and Technology (OIST) Graduate University
Researchers at the Marine Genomics Unit at the Okinawa Institue of Science and Technology (OIST) and their collaborators at the University of the Ryukyus and NTT Communications, have established a robust system to monitor mesophotic coral ecosystems using a combination of underwater robots and eDNA barcoding. Their findings have been published in the journal Coral Reefs. By collecting and analyzing genetic material that corals naturally release into the water – environmental DNA or eDNA – multiple species present in these deeper-water environments can now be identified without direct observations, using these robots. This makes it easier to study previously hard-to-access biodiversity hotspots.

Calculation sharpens imaging of protons’ insides
DOE/US Department of Energy
Nuclear scientists used a new theoretical approach to calculate a value essential for unraveling the three-dimensional motion of quarks within a proton. The researchers obtained a significantly more accurate picture of these internal building blocks’ transverse motion. The work will aid in calculations of 3D motion of quarks and gluons in future collider experiments.

Bright light may lower depression symptoms by promoting better sleep
Brigham and Women's Hospital
Why might more time in the sun boost a person’s mood? A new study led by investigators at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, suggests that sleep may hold the key.

New study reveals link between owner demographics and canine nutrition
Texas A&M University
A new study from the Dog Aging Project (DAP) at Texas A&M University and investigators at Virginia-Maryland College of Veterinary Medicine has revealed that the reasons owners choose certain diets for their dogs can vary widely, with owner age making a bigger difference than income or education level.
