Structural elements of archaea Archaea, a unique domain of life, were discovered in the 1970s in extreme environments such as hot springs and salty lakes, with notable early studies conducted in locations like Yellowstone National Park in the United States. Initially considered unusual bacteria, their distinct genetics and biochemistry led to their recognition as a separate domain, emphasizing microbial diversity and evolutionary complexity.

When do stereotypes undermine indirect reciprocity? iStock / bakhtiar_zein When do stereotypes undermine indirect reciprocity? Researchers from Penn and Princeton develop a model to evaluate how reputation and indirect reciprocity affects cooperative behaviors.
The role of history in how efficient color names evolve (Image: iStock/scyther5) The role of history in how efficient color names evolve In a new study, biology and psychology researchers show how existing color vocabularies constrain future options for efficient color vocabularies.
When is the best time to take L-theanine—morning or night? Penn In the News Good Housekeeping When is the best time to take L-theanine—morning or night? According to Colleen Tewksbury of the School of Nursing, research suggests that L-theanine may help support stress management, sleep, and potentially weight management. In hot water: Coral resilience in the face of climate change Researchers led by Katie Barott collect data from coral populations in Kanohe Bay, Hawaii. (Image: Courtesy of Kristen Brown) In hot water: Coral resilience in the face of climate change Over a decade, researchers from Penn studied coral species in Hawaii to better understand their adaptability to the effects of climate change. Protein partners identified as potential key for fetal bone development Image: iStock/Christoph Burgstedt Protein partners identified as potential key for fetal bone development A pair of proteins, YAP and TAZ, could contribute to the development of healthy, strong bones by directing early cell movement and blood vessel generation. More than skin deep: A molecular and mechanistic look at pigmentation variation PIK Professor Sarah Tishkoff led a collaborative team of researchers who have discovered key insights into the molecular basis of skin color differences among Africans. “There’s so much genetic diversity in African populations, but they’ve also been historically underrepresented in studies,” Tishkoff says. “Our findings offer more information on these populations and paint a clearer picture of human evolution.” (Image: Courtesy of Sarah Tishkoff and Alessia Ranciaro) More than skin deep: A molecular and mechanistic look at pigmentation variation A new collaborative study offers a better understanding of genes and variants responsible for skin color, providing insights into human evolution and local adaptation. Research shows how stress activates neurons that disrupt sleep Image: iStock/Prostock-Studio Research shows how stress activates neurons that disrupt sleep New research from Penn Medicine shows suppressing these neurons may be a promising target for therapies to treat stress-related sleep disorders, like insomnia and PTSD.
