New sensor enables 'smart diapers,' range of other health monitors

Waaahhh! While babies have a natural mechanism for alerting their parents that they need a diaper change, a new sensor developed by researchers at Penn State could help workers in daycares, hospitals and other settings provide more immediate care to their charges.

In-place manufacturing method improves gas sensor capabilities, production time

When used as wearable medical devices, stretchy, flexible gas sensors can identify health conditions or issues by detecting oxygen or carbon dioxide levels in the breath or sweat.

Jared Ali named director of the Penn State Center for Chemical Ecology

Jared Ali, Dorothy Foehr Huck and J. Lloyd Huck Chair of Chemical Ecology and associate professor of entomology in the College of Agricultural Sciences, has been named director of the Penn State Center for Chemical Ecology (CCE).

Laser writing may enable ‘electronic nose’ for multi-gas sensor

Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution, thanks to a Penn State collaboration. Huanyu “Larry” Cheng, assistant professor of engineering science and mechanics in the College of Engineering, and Lauren Zarzar, assistant professor of chemistry in Eberly College of Science, and their teams combined laser writing and responsive sensor technologies to fabricate the first highly customizable microscale gas sensing devices.

Jared Ali named Huck Chair of Chemical Ecology

Jared Ali, associate professor of entomology in Penn State's College of Agricultural Sciences, has been named the Dorothy Foehr Huck and J. Lloyd Huck Chair of Chemical Ecology by the University’s Huck Institutes of the Life Sciences.

Managing habitat for flowering plants may mitigate climate effects on bee health

Warm, wet weather conditions and changing climate negatively influence the nectar intake and nutritional health of honey bees, but maintaining large tracts of grassy natural habitat with flowering plants around apiaries may help to mitigate the detrimental effects of climate, according to a new study by an international team of researchers.

Little crop of horrors

An international team of researchers has received a grant from the Human Frontier Science Program to investigate how carnivory-related genes, such as those involved in digestion, could help crops not only avoid pests, but also thrive in low-nutrient environments.

Silencing the alarm

An enzyme in the saliva of certain insects prevents their food plants from warning neighboring plants of an attack.

Plants defend against insects by inducing 'leaky gut syndrome'

Plants may induce "leaky gut syndrome" — permeability of the gut lining — in insects as part of a multipronged strategy for protecting themselves from being eaten, according to researchers at Penn State.

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.
