Battling disease with ultraviolet light

The study aims to develop optical radiation products used in large-scale sanitation processes and create a lamp with both germicidal and lighting elements. Researchers will test different wavelengths of ultraviolet light against coronaviruses like COVID-19.

Which COVID-19 models should we use to make policy decisions?

Researchers developed a new process to combine multiple disease models for outbreak management, reducing uncertainty and providing better tools for decision makers. The three-part process allows policymakers to evaluate valuable ideas from across the modeling community and identify critical uncertainties to prioritize research directions.

'Gargantuan' hail in Argentina may have smashed world record

A recent storm in Argentina produced hailstones up to 9.3 inches across, potentially setting a new world record. Researchers suggest classifying such large hailstones as 'gargantuan' and emphasize the need for more awareness and data collection to better understand these extreme events.

Iron deficiency in corals?

Microalgae in coral cells may compensate with other metals when iron is limited, potentially affecting vital biological functions. Research found that different species of microalgae acquire other trace metals in unique quantities, which could have cascading effects on coral health.

Study finds evidence for existence of elusive 'metabolon'

Researchers at Penn State have directly observed functional metabolons involved in generating purines, the most abundant cellular metabolites. The findings suggest that enzymes are not haphazardly located throughout cells but instead occur in discrete clusters, or metabolons, that carry out specific metabolic pathways.

Amazonian crops domesticated 10,000 years ago

Researchers confirm early plant cultivation in southwestern Amazonia, dating back to 10,350 years ago, with evidence of manioc and squash. The discovery suggests that the earliest inhabitants were not just hunter-gatherers but also engaged in plant cultivation.

Organic soybean producers can be competitive using little or no tillage

A new study by Penn State researchers found that organic soybean producers using no-till and reduced-tillage production methods can achieve similar yields at competitive costs compared to traditional tillage-based production. This sustainable method reduces labor, fuel, and input costs while conserving soil health and water quality.

Scientists tap unused energy source to power smart sensor networks

Researchers have created a device capable of converting low-level magnetic fields into usable electricity, with 400% higher power output than existing technology. This technology has significant implications for designing self-powered wireless sensor networks in smart buildings, potentially leading to substantial energy savings.

Engineers model mutations causing drug resistance

Engineers have developed a method to predict which mutations will occur in people, making it easier to create effective pharmaceuticals. The researchers used algorithms similar to those used in chemical physics to model how evolution works and found that biased random events play a big part in the evolution of resistance in leukemia.

Improving success of giraffe translocations

Researchers developed guidelines for giraffe translocations to ensure long-term population viability, including ideal group composition and decision-making processes. A founding population of 30 females and 3 males is recommended for initial translocations, while larger groups can be used to maintain genetic diversity.

Pesticide seed coatings are widespread but underreported

The study found that farmers know less about pesticides applied to their seeds than those applied in other ways, due to seed treatments being exempt from labeling requirements. This lack of knowledge can lead to overuse of pesticides, harming the environment and farmers' health. The researchers recommend improved labelling of pesticide...

Compartments without borders

Researchers at Penn State developed a laboratory method to create membraneless compartments within a liquid, allowing them to segregate and concentrate components for important cellular functions. The findings could provide insight into how cells use these compartments to perform different tasks in different locations, with potential a...
