A new study led by Penn State researchers finds that U.S. firms actively engaged in creating innovative products or processes are more likely to expand into international markets. The findings, which apply to both rural and urban companies, could inform efforts to boost U.S. exports.
Why buy when you can rent? From cars to high-end clothing, the short-term renting or sharing of consumer goods through "branded access offers" has become an increasingly popular alternative to the traditional ownership model. But such time-limited consumption may have unintended consequences for the parent brands that offer them, according to a new study co-written by a University of Illinois Urbana-Champaign expert in consumer-brand relationships.
A reaction wheel—one of the heaviest parts of a space mission, its changing rotation used to shift a satellite's orientation—seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgart Institute of Space Systems (IRS). Arc-heated gas in the test chamber reaches speeds of several kilometers per second, reproducing reentry conditions, while the reaction wheel itself is being rotated, reproducing the tumbling that takes place as a satellite plunges through the atmosphere.
In the Roman Empire, custom taxes on spices, black pepper in particular, accounted for up to a third of the empire's annual income. During the late Middle Ages, European efforts to cut out middlemen and monopolize the spice trade led to colonization in Asia. Historically, non-timber forest products have frequently played a key role in the global economy.
In the rugged terrain of the western United States, where wildfires rage unchecked, a surprising connection emerges with the tumultuous skies of the central US. A recent study published in Advances in Atmospheric Sciences explores the intriguing relationship between wildfires in the West and hailstorms in the Central US.
We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied in a complete way during cell division. Telomeres, which cap the ends of chromosomes, play a critical role in this cell-renewal process—with a direct bearing on health and disease.
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.
Placozoans are among the simplest animals and occur worldwide in coastal waters. It was previously assumed that the tiny creatures, which measure just a few millimeters, live either on hard surfaces—such as rocks, corals, and mangrove roots—or float in open coastal waters as so-called "swarmer" stages.
Most disease-causing bacteria are known for their speed: In mere minutes, they can double their population, quickly making a person sick. But just as dangerous as this rapid growth can be a bacterium's resting state, which helps the pathogen evade antibiotics and contributes to severe chronic infections in the lungs and blood, within wounds, and on the surfaces of medical devices.
NASA is now publicly distributing science-quality data from its newest Earth-observing satellite, providing first-of-their-kind measurements of ocean health, air quality, and the effects of a changing climate.
A new set of maps that document the movements of ungulates was published today in the fourth volume of the Ungulate Migrations of the Western United States. The maps in this collaborative U.S. Geological Survey report series reveal the migration routes and critical ranges used by ungulates, or hooved mammals, in the western U.S., furthering scientists' understanding of the geography of big game migrations.
Spectroscopic ellipsometry is widely adopted in semiconductor processing, such as in the manufacturing of integrated circuits, flat display panels, and solar cells. However, a conventional spectroscopic ellipsometer, as shown in Fig.1a, typically modulates the polarization state via mechanical rotation of the compensator or analyzer. For spectral detection, it either requires wavelength scanning or the use of a multi-channel spectrometer. The resulting system is often bulky, complex, and require multiple measurements.
Researchers from Nanyang Technological University, Singapore (NTU Singapore), have created a method that extracts more than 80% of the available protein in grain leftovers from brewing beer, commonly known as brewers' spent grain.
When it arrived en masse for the COVID pandemic, remote working was hailed as an arrangement that boosted work-life balance and slashed commuter-related misery and pollution. But it would appear its golden days are over.
Twenty-nine of the more than 2,000 water treatment facilities in Colorado do not meet strict new federal limits on the amount of dangerous "forever chemicals" in their drinking water supplies and it will cost millions to clean those toxins out of the water.
A study by the University of Southampton has found that market forces have provided good food price stability over the past half century, despite extreme weather conditions.
Researchers have recently found out how to use algae to convert ammonia and nitrates into a nutrient-rich fertilizer or fish feed ingredients.
New England's dairy industry continues to evolve in response to significant market challenges that include a decreased demand for milk and higher production and land costs. However, there is also ongoing evidence that organic dairy farming can provide environmental benefits—such as reducing methane emissions—which could further differentiate their products as well as help qualify farms for new government initiatives to reduce methane through innovative management practices.
Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the moon or Mars, it is a significant hazard that must be mitigated. That's why researchers at NASA's Kennedy Space Center in Florida are seeking innovative ways to use Electrodynamic Dust Shield (EDS) technology.
Plants can be temperamental. Even weeds along the side of highways or pushing their way up in the cracks of concrete sidewalks can get stressed out by dehydration, cold, excess salt and more. Researchers at Hiroshima University have identified 14 genes that thale cress—a plant commonly used in genetic investigations since its genome is well documented—express more when responding to five specific stressors, as well as eight genes that the plant suppresses.
Bird collisions with buildings are nothing new, but a new study by scientists at The University of New Mexico sheds light on a potential cause.
If you're outside enjoying the spring sunshine, then chances are, ticks are too. However, new research from Simon Fraser University (SFU) suggests the use of ant pheromones as a topical repellent, or as an environmental barrier, may help protect hikers and campers from the harmful bites of black-legged ticks, which could carry Lyme disease.
Short-term pain for long-term gain: That might be one way to describe the results of new research from the Alberta School of Business on the impact of diversity and inclusion (D&I) practices on business firms.
Top management teams at most businesses are charged with maximizing shareholder wealth, making any actions that impede this goal their sole responsibility.
Adding one simple rule to an idealized game of billiards leads to a wealth of intriguing mathematical questions, as well as applications in the physics of living organisms. This week, researchers from the University of Amsterdam, including two masters' students as first authors—have published a paper in Physical Review Letters about the fascinating dynamics of billiards with memory.
