Over the past few weeks, the Taliban has quickly taken control of major cities throughout Afghanistan, unraveling 20 years of efforts under United States occupation. Fear and uncertainty only intensified after the Taliban installed themselves in the presidential palace in Kabul on Aug. 15.William Nomikos, assistant professor of political science in Arts & Sciences at Washington University in St.
Cells are the basic units of structure and function in all forms of life on Earth, from humans and animals to yeasts and bacteria. But a cell itself is made up of even smaller working pieces called organelles. Understanding how a cell commits resources to building new parts — and eventually divides into two cells — is the focus of a new grant for physicist Shankar Mukherji of Washington University in St.
Research from the lab of Deanna Barch and Joan Luby shows a lasting relationship between childhood poverty, brain development.
Many employers have already begun transitioning employees back to the office, while others plan to resume in-office work in the coming months. But after more than a year of working from home, is returning to business as usual even possible? Or desirable?Employees have changed amid this pandemic. The more a company can match employee preferences and the optimal work conditions required for a given role, the better off they’ll be in terms of hiring and employee retention, according to Peter Boumgarden, an organizational behavior expert at Washington University in St.
The cabbage butterfly, voracious as a caterpillar, is every gardener’s menace. Turns out, these lovely white or sulfur yellow butterflies started trying to take over the planet millions of years before humans ever set foot on it.
Democrats have called for a permanent expansion of the monthly child tax credit, which will continue through the end of the year. In making the expanded credit permanent, lawmakers can leverage the power of child development accounts to build assets for all children in the United States, says a Washington University in St. Louis expert on asset building.
Biologists analyzed data from 2,600 lizard species worldwide and discovered that, while hundreds of different types of lizards have independently evolved arboreal lifestyles, species that possessed sticky toepads prevailed.
Meat and dairy played a more significant role in human diets in Bronze Age China than previously thought. A new analysis also suggests that farmers and herders tended to sheep and goats differently than they did their cows, unlike in other parts of the world — keeping cows closer to home and feeding them the byproducts of grains that they were growing for their own consumption, like the grass stalks from millet plants.
Research from the lab of Shantanu Chakrabartty reveals constraints can lead to learning in AI systems.
Pharmaceutical and biotechnology companies topped the 2021 RQ Top 50 list of the most innovative U.S. companies. The annual ranking identifies the smartest R&D spenders - those companies that both spend big (at least $100 million in R&D) and provide the greatest returns to shareholders from that investment.
Given the increased interest in sports and exercise around the Olympics underway in Tokyo, events such as the Summer Games represent an unrealized opportunity to improve global health, finds a new paper from the Brown School at Washington University in St. Louis.
An untapped trove of desirable drug-like molecules is hidden in the genomes of Streptomyces bacteria — the same bacteria responsible for the first bacterial antibiotics to treat tuberculosis back in the 1940s. Isolating them, however, has proved challenging. Now, biologists at Washington University in St. Louis are using comparative metabologenomics to try to uncover what may be “silencing” Streptomyces and preventing it from producing desirable compounds encoded by its genes.
Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. Using tip-growing cells in moss and pollen tubes of flowering plants, a new study is among the first to directly investigate what one type of these mechanosensitive ion channels -- PIEZO channels -- is doing in plant cells, and how.
Despite assumptions, dsRNA has traits that make it stand apart from the more common single-stranded RNA. The finding has implications for a range of fields
The body’s so-called good cholesterol may be even better than we realize. New research from Washington University School of Medicine in St. Louis suggests that one type of high-density lipoprotein (HDL) has a previously unknown role in protecting the liver from injury. This HDL protects the liver by blocking inflammatory signals produced by common gut bacteria.
Inflexible schedules and biased hiring practices, combined with gendered cultural norms around breadwinning and caregiving, lead to discrimination against mothers and perpetuate existing gender inequalities in the workplace, finds two new studies from Washington University in St. Louis.
