The Notre Dame study looks at performance based on the impact the CEO has on the firm within the context of the performance they inherited and the time period in which they ran the firm.
Gut bacteria can influence brain health, according to a study of mice genetically predisposed to develop Alzheimer’s-like brain damage. The study, by researchers at Washington University School of Medicine in St. Louis, indicates that gut bacteria produce compounds that influence the behavior of immune cells, including ones in the brain that can cause neurodegeneration. The findings suggest a new approach to treating Alzheimer’s and other neurodegenerative diseases.
Something is amiss in the Butterfly Nebula. When astronomers compared images from 2009 & 2020, they saw dramatic changes in its "wings." Powerful winds are driving complex alterations of nebular material. It's unknown how such activity is possible in what should be a “largely moribund star with no remaining fuel.”
Research suggests that findings about human risk preferences also apply to risk-taking in chimpanzees, our closest evolutionary ancestor in the animal kingdom, and that individual chimps’ risk preference is stable and trait-like across situations.
A team of researchers led by The University of Texas MD Anderson Cancer Center has developed a novel delivery system for messenger RNA (mRNA) using extracellular vesicles (EVs). The new technique has the potential to overcome many of the delivery hurdles faced by other promising mRNA therapies.

Scientists have discovered something unexpected about the Triangulum galaxy: In this satellite galaxy, a close companion of the much larger Andromeda galaxy, old and new stars occur in separate parts of the its structure, something not seen in galaxies like our own and so far not reporter for other satellite galaxies.
The opportunistic bacterium Acinetobacter baumannii rarely sickens healthy people but causes serious infections in hospitalized patients. A study, in mice, from Washington University School of Medicine in St. Louis suggests that Acinetobacter can hide undetected in bladder cells and then reactivate when stimulated by medical intervention. The findings suggest that patients may bring Acinetobacter into hospitals and that screening patients could supplement current infection-control efforts.
By peering into a well-known star cluster within the Small Magellanic Cloud, Webb’s NIRCam instrument has revealed many new pockets of star formation that have never been seen. Further, new structures appear in this image that provide a window into the stars feeding within.
A new paper by a team at Los Alamos National Laboratory is giving researchers new insight into how countries respond to systemic shocks such as the COVID-19 pandemic.
Astronomers discovered that the star Gaia17bpp gradually brightened over a 2 1/2-year period. But follow-up analyses revealed that the star itself wasn’t changing. Instead, it's likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, "dusty" stellar companion.
Early retirement can accelerate cognitive decline among the elderly, according to research conducted by faculty at Binghamton University, State University of New York.
Save the ... parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn -- and that means not just fewer worms, but losses for the entire ecosystem.

A team of researchers led by Young-Shin Jun at the McKelvey School of Engineering at Washington University in St. Louis found that nanoplastics facilitate formation of manganese oxide on polystyrene nanoparticles.
New experiments that show that eukaryotic cells can robustly control average fluctuations in organelle size. By demonstrating that organelle sizes obey a universal scaling relationship that the scientists predict theoretically, their new framework suggests that organelles grow in random bursts from a limiting pool of building blocks.
Meet Adrien Florio, a postdoctoral research associate and fellow in Brookhaven Lab’s Nuclear Theory Group that is contributing his unique perspective and experience to the Co-design Center for Quantum Advantage's theory and applications subthrust.
Scientists are working to transform carbon dioxide into chemical solar fuels. To advance this process, researchers have identified a new hybrid material that consists of a light-absorbing semiconductor and a cobalt catalyst. The research extends scientific efforts to identify new ways to store energy and to efforts to understand how light-absorbing hybrid systems can drive the catalytic production of chemical fuels using solar energy.
The medical emergency suffered by Damar Hamlin of the Buffalo Bills underscores the importance of speed when responding to cardiac arrest. Two Penn State Health physicians offer guidance.

Following a modified Atkins diet high in fat and low in carbohydrates plus taking medication may reduce seizures in people with tough-to-treat epilepsy, according to a study published in the January 4, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Retinal cells grown from stem cells can reach out and connect with neighbors, according to a new study, completing a “handshake” that may show the cells are ready for trials in humans with degenerative eye disorders.Over a decade ago, researchers from the University of Wisconsin–Madison developed a way to grow organized clusters of cells, called organoids, that resemble the retina, the light-sensitive tissue at the back of the eye.
Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC)—a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory—to see the shape and details inside atomic nuclei. The method relies on particles of light that surround gold ions as they speed around the collider and a new type of quantum entanglement that’s never been seen before.
These are Hubble Space Telescope images of two massive clusters of galaxies. The artificially added blue color is translated from Hubble data that captured a phenomenon called intracluster light. This extremely faint glow traces a smooth distribution of light from wandering stars scattered across the cluster. Billions of years ago, the stars were shed from their parent galaxies and now drift through intergalactic space alone.
Physicians across the nation are describing an increase in requests from women for permanent contraception. The anecdotal reports by clinicians come in the wake of the U.S. Supreme Court ruling that overturned Roe v. Wade, the constitutional right to abortion.

Studying mice, researchers at Washington University School of Medicine in St. Louis have found that proteins made by stem cells to help regenerate the cornea may become new targets for treating and preventing injuries to the cornea related to dry eye disease. When eyes are dry, the cornea is more susceptible to injury.
