Orange is the new ‘block’

Orange is the new ‘block’

New research from Washington University in St. Louis reveals the core structure of the light-harvesting antenna of cyanobacteria — including features that both collect energy and block excess light absorption. Orange carotenoid protein plays a key protective role, according to Haijun Liu, research scientist in chemistry in Arts & Sciences at Washington University in St. Louis.
Secrets of the ‘lost crops’ revealed where bison roam

Secrets of the ‘lost crops’ revealed where bison roam

Research from Washington University in St. Louis helps flesh out the origin story for the so-called “lost crops” of the Midwest and Northeast. These plants that may have fed as many Indigenous people as maize, but until the 1930s had been lost to history. Natalie Mueller, assistant professor of archaeology in Arts & Sciences at Washington University in St. Louis, shares evidence that bison were “co-creators” — along with Indigenous peoples — of landscapes of disturbance that gave rise to greater diversity and more agricultural opportunities.

What cold lizards in Miami can tell us about climate change resilience

Scaled survivors of the coldest night in south Florida’s recent history all converged on the same new, lower limit of thermal tolerance, regardless of their species’ previous ability to withstand cold. Biologist James Stroud in Arts & Sciences at Washington University in St. Louis led the team that reported the findings in the journal Biology Letters.

Sicker livestock may increase climate woes

Climate change is affecting the spread and severity of infectious diseases around the world — and infectious diseases may in turn be contributing to climate change, according to new research from Washington University’s Living Earth Collaborative working group led by biologist Amanda Koltz in Arts & Sciences.
Hengen awarded $1.8M to study sleep’s contribution to brain function

Hengen awarded $1.8M to study sleep’s contribution to brain function

Keith Hengen, assistant professor of biology in Arts & Sciences at Washington University in St. Louis, received a three-year $1.8 million grant to study the role of sleep and waking behavior in shaping the brain’s neural dynamics. His research will help scientists understand how sleep contributes to healthy cognition and shed light on the mechanisms by which disrupted sleep worsens neurodegenerative and mental health disorders.
How plants survive in the dark

How plants survive in the dark

Deprived of light, plants are unable to transform carbon dioxide from the atmosphere into sugar molecules. New research led by biologist Richard Vierstra in Arts & Sciences at Washington University in St. Louis provides an in-depth look at how maize responds at a cellular level.
