Plate tectonics not needed to sustain life

A computer model of a planet's lifecycle reveals stagnant lid planets can sustain liquid water and potentially life for billions of years. The presence and amount of heat-producing elements are key indicators of habitability, according to Penn State researchers.

Poor mental health days may cost the economy billions of dollars

A study by Penn State researchers found that poor mental health days can lead to a 1.84% drop in per capita real income growth rate, resulting in $53 billion less total income each year. Investing in mental health resources may help mitigate these effects, particularly in rural counties with limited access to services.

Oil biodegradation inhibited in deep-sea sediments

Degradation rates of oil were slower in the dark and cold waters of the Gulf of Mexico than at surface conditions. Oil biodegradation rates decreased by 4 percent for every 328 feet of increase in water depth, with complete degradation taking 42 days in sediments deeper than 3280 feet.

Link found between bitter-taste sensitivity and cancer risk

Researchers found that older women with high bitter-taste sensitivity had a significantly higher cancer risk, despite not consuming fewer vegetables. The study suggests that the relationship between bitter-taste sensitivity and cancer may relate more to overall diet quality than just vegetable consumption.

Finding the proteins that unpack DNA

Researchers developed a high-throughput method to screen and categorize transcription factors based on their ability to displace nucleosomes. The study identified both new and previously known nucleosome-displacing factors, which tend to be highly abundant in the nucleus and bind tightly to DNA.

Athletic 'pull' increases campus diversity

Research by Penn State's Clio Andris found that universities attract athletes from afar, increasing diversity on campuses. The study analyzed data from over 160,000 student-athletes and found that Ivy League schools and less centrally located schools have strong pull rankings.

Carbon dioxide-to-methanol process improved by catalyst

Researchers have developed a new catalyst that increases the rate of methanol formation by three times over palladium alone and four times over copper alone. The catalyst combines palladium and copper in a precise atomic ratio, creating an ideal surface structure for efficient CO2-to-methanol conversion.

Your brain with a migraine

An international team of researchers has identified the electrical activity specific to the start of migraines and demonstrated a way to stop it in animal experiments. They found that spreading depolarization, seen in migraines, can be stopped with an opposite direction of electrical current used to turn off seizures.

Giving up on your goal? Read this first

A series of setbacks can lead to an 'action crisis,' causing individuals to question the importance of their goal. New research reveals that repeated struggles and setbacks can cause people to devalue their goal, making it harder to stick to it. However, knowing ahead of time when an action crisis may occur allows individuals to prepar...

Nuclear power shutdowns won't spike power prices

A new study finds that the shutdown of two nuclear power plants in Pennsylvania will not significantly impact power prices due to low natural gas prices. The research suggests that efficient natural gas power plants have increased capacity, making it difficult for nuclear power to compete with competitive market outcomes.

Hats on for Easter Island statues

The study uses archaeological evidence and physics-based processes to describe how the islanders placed the hats on the statues. The researchers propose that workers would rotate, leverage, and pivot the hats onto the statue tops using small wooden levers.

Oil and gas wastewater as dust suppressant less than ideal

A multidisciplinary team of researchers found that oil and gas wastewater can be effective at suppressing dust, but it also carries high salt, organic, and radioactivity concentrations. The team recommends using alternative materials or treatment to remove contaminants before using the wastewater.

Climate change forced zombie ant fungi to adapt

Researchers found that climate change led to a shift in the host choice of zombie ant fungi, from leaves to twigs and bark, as tropical forests transitioned to temperate areas. The study, published in Evolution, reveals that this adaptation occurred independently in different locations around the world.

Posttraumatic stress affects academics

A new Penn State research study found that posttraumatic stress symptoms increase risks for academic difficulties in student veterans. Partnered women were particularly affected due to relationship problems impacting their academic functioning.

Flexible, highly efficient multimodal energy harvesting

Researchers at Penn State developed a new composite material that can efficiently harvest mechanical and thermal energy using a 3D piezoelectric ceramic foam supported by a flexible polymer. The material outperforms traditional piezoelectric composites, offering improved flexibility and energy output.
