Consistent with the expectation that experts view native "grapey"-associated odors as a fault, wines with medium to high concentrations of methyl anthranilate approximating the intensity of the compound in Concord or Niagara wines were largely rejected by wine experts in California.

Sensory tests suggest 'liking' wines made with native grapes a learned response

Consumer preference or aversion to wines made from native grapes — such as Concord, Niagara and Catawba, which are grown in North America — may depend on early exposure to the fruits' sweet, ultra "grapey" taste and aroma, according to researchers who conducted sensory tests with wine drinkers in Pennsylvania and California.

Researchers find features that shape mechanical force during protein synthesis

Like any assembly line, the body’s protein-building process generates a mechanical force as it produces these important cellular building blocks. Now, a team of researchers suggest they are one step closer to understanding that force. They also built a mathematical model to help guide scientists with future investigations into how the body creates proteins

When Pennsylvania ground beetles are not defending themselves they are friends of agriculture, consuming up to their body weight daily, eating pests such as aphids, moth and beetle larvae, as well as slugs and snails. They can spray their defensive chemicals a distance multiple times their body length. IMAGE: NICK SLOFF PENN STATE

Material that shields beetle from being burned by its own weapons holds promise

Carabid beetles produce caustic chemicals they spray to defend themselves against predators, and the compound that protects their bodies from these toxic substances shows promise for use in bioengineering or biomedical applications, according to Penn State researchers.

Indigenous hunters have positive impacts on food webs in desert Australia

Australia has the highest rate of mammal extinction in the world. Resettlement of indigenous communities resulted in the spread of invasive species, the absence of human-set fires, and a general cascade in the interconnected food web that led to the largest mammalian extinction event ever recorded. In this case, the absence of direct human activity on the landscape may be the cause of the extinctions, according to a Penn State anthropologist.

The new AggTag method allows researchers to see the previously undetectable but potentially disease-causing intermediate forms of proteins as they misfold. The method uses fluorescence to simultaneously detect two different proteins (red, green) within the cell (blue). Credit: Zhang lab, Penn State

New method uses fluorescence to identify disease-causing forms of proteins

A new method uses fluorescence to detect potentially disease-causing forms of proteins as they unravel due to stress or mutations. A team of researchers from Penn State and the University of Washington reengineered a fluorescent compound and developed a method to simultaneously light up two different proteins as they misfold and aggregate inside a living cell, highlighting forms that likely play a role in several neurodegenerative diseases including Alzheimer’s and Parkinson’s.

Troy Ott to discuss "the improbable series of events that led to your birth"

At this month’s "Science on Tap" event, Huck Associate Director and professor of reproductive biology Troy Ott will discuss viviparity — the development of an embryo inside the body leading to the birth of a live offspring. Viviparity is thought to have evolved from egg-laying animals. Ott's talk will focus on one of the enigmas of live birth that relates to the mother’s immune system.

A new program developed by researchers from Penn State and Microsoft Azure automatically detects regions of interest within images, alleviating a serious bottleneck in processing photos for wildlife research. The new program successfully identified the region of interest—unique marks on giraffe torsos—in giraffe photos, even when the giraffe occupied a small region of the photo or when they were partially covered by vegetation.

Toward automated animal identification in wildlife research

A new automated method to prepare digital photos for analysis will help wildlife researchers who depend on photographs to identify individual animals by their unique markings. A wildlife biologist from Penn State teamed up with scientists from Microsoft Azure, a cloud computing service, using machine learning technology to improve how photographs are turned into usable data for wildlife research. A paper describing the new technique appears online in the journal Ecological Informatics.

Simple drug combination creates new neurons from neighboring cells

A simple drug cocktail that converts cells neighboring damaged neurons into functional new neurons could potentially be used to treat stroke, Alzheimer’s disease, and brain injuries. A team of researchers at Penn State identified a set of four, or even three, molecules that could convert glial cells—which normally provide support and insulation for neurons—into new neurons.
