Organic molecules found in a meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago, according to an analysis to be published this week in Science.

A grant from the National Science Foundation will allow Shayla Sawyer, a professor in the Department of Electrical, Computer, and Systems Engineering at Rensselaer Polytechnic Institute, and Rick Relyea, a professor of biological sciences at Rensselaer, to better understand the growing problem of harmful algal blooms (HABs).

Whether a transformer catches fire in a power grid, a species disappears from an ecosystem, or water floods a city street, many systems can absorb a certain amount of disruption. But how badly does a single failure weaken the network?

A predictive model of a polarized group, similar to the current U.S. Senate, demonstrates that when an outside threat – like war or a pandemic – fails to unite the group, the divide may be irreversible through democratic means. 

In research published Langmuir, a team led by Steven Cramer, an endowed chair professor of chemical and biological engineering, explored the fundamentals of how different molecules interact with various surfaces during the purification process.

Having challenged the idea that our environment cannot alter our genetically controlled 24-hour sleep-wake cycle, circadian rhythm researcher Jennifer Hurley has embarked on a new project tracing the mechanism between environmental signals and the circadian clock.

Materials and mechanical scientists are using machine learning to rapidly vet combinations of elements that could be used in next-generation environmental barrier coatings needed to protect vehicles traveling in the extreme conditions of aerospace and space environments. The project, led by researchers at Rensselaer Polytechnic Institute, is supported by the National Science Foundation.

Faculty from Rensselaer Polytechnic Institute served as experts in an exchange of information about developments in the field of sustainable energy, large-scale environmental change, and innovative and interdisciplinary research into energy storage and smart systems in the built environment on a recent visit by two members of the U.S. Congress.

TROY, N.Y. — A novel experiment aimed at studying the mechanics of amyloid fibrils — a type of protein aggregation associated with diseases like diabetes, Alzheimer’s, and Parkinson’s — started today aboard the International Space Station (ISS), led by a team at Rensselaer Polytechnic Institute.

Like many other cells and organs within the body, cardiac cells possess a type of asymmetry that may play an important role in healthy heart formation and could serve as the basis for interventions to prevent congenital heart defects.
