In a new study that uses fruit as the loot, UC Berkeley researchers found that chimps steal less from their friends, and that friendship status affected the emotional expression of both victim and thieves. Closely bonded chimps swiped pineapple pieces from one another less frequently than those with weaker relationships. Additionally, victims were quicker to calm down when the thief was a friend, and thieves showed less hostility when stealing from a bonded pal than from a non-friend. The new research deepens our understanding of the emotional underpinnings of our social lives.
To bridge the gap between carbon monoxide's notorious toxicity and its hidden potential in biology, Dr. Matthew R. Dent, assistant professor of chemistry in the College of Liberal Arts and Sciences at Wayne State University, has received a prestigious U.S. National Science Foundation (NSF) Faculty Early Career Development (CAREER) award. The five-year, $749,702 grant supports his project, "CAREER: Carbon Monoxide Sensing, Selectivity, and Signaling in Microbes."
Researchers at Upstate Medical University published a study in PLOS Biology that reveals a key mechanism underlying nervous system organization and may inform future research into myelin-related neurological diseases. Myelin is essential for efficient nerve signaling and healthy brain and spinal cord function. Damage to myelin is associated with conditions such as multiple sclerosis and other neurological disorders. By identifying how myelin sheath length is regulated, this research advances understanding of nervous system development and provides a foundation for future investigations into myelin repair and regeneration.
For nearly 30 years, a small fossil from Scotland has been celebrated as one of the earliest known reptiles. A new study is rewriting that story.
Researchers have answered a longstanding question about how certain non-enveloped viruses punch through the cell membrane to deliver their genetic material. The findings deepen understanding of virology and could aid the biotech industry’s search for ways to deliver relatively large therapeutic agents into cells to treat or prevent disease. Work was made possible by an advanced imaging technique known as cryo-electron tomography, or cryo-ET, at HMS.
As a deadly fungal disease ravages wild frog populations around the globe, scientists have identified potential locations in Panama where amphibians might persist despite the presence of disease, according to new research from the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) and Smithsonian Tropical Research Institute (STRI) published today in the Journal for Nature Conservation.
