Exercise may help teens sleep longer, more efficiently

Getting more exercise than normal — or being more sedentary than usual — for one day may be enough to affect sleep later that night, according to a new study led by Penn State.

Shaun Mahony employs machine learning to study gene regulation

Once the fodder of science fiction books and movies, Artificial intelligence -- AI -- and machine learning are making an impact on nearly every facet of society. Penn State’s Institute for CyberScience are among Penn State’s research leaders who are both using AI in their work and studying ways to make sure that the technology’s societal impact is as safe and as beneficial as possible.

Native forest plants rebound when invasive shrubs are removed

Removing invasive shrubs to restore native forest habitat brings a surprising result, according to Penn State researchers, who say desired native understory plants display an unexpected ability and vigor to recolonize open spots.

Plant pathology, environmental microbiology doctoral student receives NSF award

Laura Kaminsky, a doctoral student in Penn State's College of Agricultural Sciences, will be able to advance her research interests in plant pathology after receiving a grant from the National Science Foundation.

A "questing" female Ixodes scapularis (blacklegged tick) reaches out in hopes of climbing aboard a host. Researchers say the blacklegged tick, the primary vector of Lyme disease, was almost nonexistent in Pennsylvania in the 1960s but now is the state's dominant tick species.

More Than 100 Years of Data show Pennsylvania Tick Population Shift

The prevalence of the most abundant species of ticks found in Pennsylvania has shifted over the last century, according to Penn State scientists, who analyzed 117 years' worth of specimens and data submitted primarily by residents from around the state.

Alumna Laura Russo receives Robert May Prize from the British Ecological Society

PSU alumna Laura Russo has been selected to receive the Robert May Prize from the British Ecological Society, the oldest ecological society in the world. The prize recognizes the best paper by an early career researcher in the society’s scientific journal Methods in Ecology and Evolution.

A new study led by researchers at Penn State has identified the gene responsible for the color switch between the red and black color forms of the bumble bee, Bombus melanopygus. The black form is similar to other bees in the Pacific Coastal region while the red form is similar to other bees in the Rocky Mountain region. IMAGE: LI TIAN, PENN STATE

How The Bumble Bee Got Its Stripes

Researchers have discovered a gene that drives color differences within a species of bumble bees. This discovery helps to explain the highly diverse color patterns among bumble bee species as well as how mimicry — individuals in an area adopting similar color patterns — evolves.
