Community factors influence how long you'll live, study shows

A recent study by Penn State researchers found that communities with more fast food restaurants, higher population density, and jobs in the extraction industry have shorter life expectancies. Conversely, areas with growing populations, good access to physicians, and high social cohesion tend to have longer lifespans.

Community factors influence how long you'll live, study shows

A new study by Penn State researchers found that community characteristics play a significant role in determining life expectancy, with factors such as fast food restaurants, population density, and jobs in the extraction industry negatively affecting lifespan. Conversely, social capital, good access to physicians, and lower population...

Machine sucks up tiny tissue spheroids and prints them precisely

Researchers at Penn State developed a novel bioprinting technique that uses aspiration-assisted printing to place tiny tissue spheroids in precise locations, enabling the creation of homogeneous and heterocellular tissues. This method has potential applications in regenerative medicine, drug screening, and microphysiological systems.

Researchers identify breaking point of conducting material

Researchers at Penn State developed a new method to predict the temperature when plastics change from supple to brittle, which could accelerate the development of flexible electronics. The study found that a simple relationship between chemical structure and glass transition temperature can be used to predict embrittlement point.

Looking for aliens who might be looking for us

Astronomers led by Penn State graduate student Sofia Sheikh conducted a massive survey of radio emissions from 20 nearby stars, looking for technological signatures of extraterrestrial civilizations. Despite finding no technosignatures, the analysis sets rigorous limits on the presence of advanced civilizations in our galaxy.

Local genetic adaption helps sorghum crop hide from witchweed

Research finds that sorghum crops in areas with high witchweed prevalence have genetic adaptations to resist the parasite, altering hormone production. While these mutations confer some resistance, they also affect photosynthesis and growth, raising potential trade-offs.

Social media content matters for job candidates, researchers find

Researchers found that hiring managers perceive candidates with self-absorbed or overly opinionated social media profiles as less suitable for employment. The study also discovered that content suggesting drug or alcohol use has a smaller impact on perceptions of employment suitability.

Insecticides are becoming more toxic to honey bees

Researchers found that neonicotinoid seed treatments have driven a significant increase in insecticide toxicity to honey bees, particularly oral-based toxic loads, which rose by 9-fold across the US. The study highlights the need for mitigation and conservation efforts in regions with high levels of insecticide use.

Novel composite antimicrobial film could take a bite out of foodborne illnesses

A new composite film made with an antimicrobial layer has shown promise in reducing the growth of harmful bacteria on packaged meat and fish products. The film, which contains a biopolymer called pullulan and an antimicrobial compound called Lauric arginate, was found to be effective in killing pathogens such as Salmonella and E. coli.,

Select few cancer patients enroll in potentially life-extending clinical trials

Researchers found that only 0.1% of cancer patients were enrolled in clinical trials as their first course of therapy after diagnosis. White males with private health insurance and metastatic cancers are more likely to enroll, but the low enrollment rate is still troubling due to the potential for increased life expectancy.

How anti-sprawl policies may be harming water quality

Higher-density development with more impervious surfaces causes runoff, leading to increased water pollution. Agriculture also contributes significantly to water pollution, and anti-sprawl policies can prevent much-needed land-use changes that reduce pollution.

Large 'herbivores of the sea' help keep coral reefs healthy

Research suggests that maintaining a healthy size distribution of parrotfish in sea floor ecosystems is crucial for coral reef health. Experiments show that large parrotfish play a key role in controlling algae growth, and selective fishing practices could lead to an overgrowth of algae if these larger fish are removed.

Atlantic and Pacific oscillations lost in the noise

A team of meteorologists found no consistent evidence for decadal oscillatory signals in global surface temperature observations. The researchers suggest that any apparent oscillation may be due to external influences like greenhouse gas and aerosol emissions. The study has implications for decade-scale climate predictability.

Innovation is widespread in rural areas, not just cities

A new study at Penn State found that incremental improvements made by businesses outside of their firm are crucial for economic growth and employment. The 'latent' innovation index assigns scores to counties based on opportunities for improvement, showing that rural areas can foster innovation too.

Craft-beer boom linked to record-number of US states growing hops

A study by Penn State researchers found that the growth of craft breweries in the US is linked to an unprecedented expansion of hop production across 29 states. The number of breweries more than quadrupled from 992 to over 4,000 between 2007 and 2017, resulting in a five-fold increase in hop farms and acreage.
