Unlocking the secrets of the ancient coastal Maya
Peer-Reviewed Publication
After more than a decade of research, Georgia State scientist Jeffrey Glover shares what he’s learned about the people who lived on a stretch of coastline in Quintana Roo Mexico over a span of 3,000 years.
Contemporary humans are still evolving - but natural selection favours those with lower earnings and poorer education. A new study shows how natural selection effects are stronger in groups with lower income and less education, among younger parents, people not living with a partner, and people with more lifetime sexual partners. Meanwhile, natural selection is pushing against genes associated with high educational attainment, high earnings, a low risk of ADHD or major depressive disorder, and a low risk of coronary artery disease.
A team of Georgia State research administrators has developed a pioneering college-to-career pathway training program. The new Access to Careers in Research Administration (ACRA) program is now accepting applications.
(Santa Barbara Calif.) — According to long-standing canon in evolutionary biology, natural selection is cruelly selfish, favoring traits that help promote reproductive success. This usually means that the so-called “force” of selection is well equipped to remove harmful mutations that appear during early life and throughout the reproductive years. However, by the age fertility ceases, the story goes that selection becomes blind to what happens to our bodies. After the age of menopause, our cells are more vulnerable to harmful mutations. In the vast majority of animals, this usually means that death follows shortly after fertility ends.
New research shows that parents are open to talking about gun safety measures with their children’s pediatricians and willing to change firearm storage practices
Rutgers researchers enable visualization of a transient molecule that helps HIV spread. This knowledge could lead to new drug development.
For more affordable, sustainable drug options than we have today, the medication we take to treat high blood pressure, pain or memory loss may one day come from engineered bacteria, cultured in a vat like yogurt. And thanks to a new bacterial tool developed by scientists at The University of Texas at Austin, the process of improving drug manufacturing in bacterial cells may be coming sooner than we thought.
About The Study: This analysis of income and mortality data in California from 2015 to 2021 found a decrease in life expectancy in both 2020 and 2021 and an increase in the life expectancy gap by income level relative to the pre-pandemic period that disproportionately affected some racial and ethnic minority populations.
Columbia researchers announced today that they have built a nanowire that is 2.6 nanometers long, shows an unusual increase in conductance as the wire length increases, and has quasi-metallic properties. Its excellent conductivity holds great promise for the field of molecular electronics, enabling electronic devices to become even tinier.
Scientists and physicians at UC San Diego and Scripps Research describe how wastewater sequencing provided dramatic new insights into levels and variants of SARS-CoV-2 on campus and in the broader community — a key step to public health interventions in advance of COVID-19 case surges.
Barrier islands protect the coastline from storms, storm surge, waves and flooding. They can act as a buffer between the ocean and beachfront property. As sea level rises, barrier islands retreat, or move closer toward the shore, which diminishes the buffer and protection. New information published today shows the retreat of coastal barrier islands will accelerate by 50 percent within a century, even if sea level continues to rise at its present rate.
New tools developed at Scripps Research and UC San Diego are helping public health officials around the world get vital information about pathogen variants from wastewater.
