The international journal Earth-Science Reviews published a paper offering an overview of the lava tubes (pyroducts) on Earth, eventually providing an estimate of the (greater) size of their lunar and Martian counterparts.
Ecologists at the University of Turku, Finland, have discovered that the food hoards pygmy owls collect in nest-boxes ("freezers") for winter rot due to high precipitation caused by heavy autumn rains and if the hoarding has been initiated early in the autumn. The results of the study show that climate change may impair predators' foraging and thus decrease local overwinter survival. The study has been published in the internationally esteemed Global Change Biology journal.
In a paper published in the journal Cancer Research, professor Levi Waldron, post-doctoral fellow Ludwig Geistlinger, and colleagues at the Institute for Implementation Science in Population Health (ISPH) at the CUNY Graduate School of Public Health and Health Policy (CUNY SPH) provide new insights into how ovarian cancer grows and evolves within a person.
B cells are white blood cells that develop to produce antibodies. These antibodies, or immunoglobulins, can bind to harmful foreign particles (such as viruses or disease-causing bacteria) to stop them invading and infecting the body's cells. Each B cell carries an individual B cell receptor (BCR) which determines which particles it can bind, rather like each lock accepts a different key. There are many millions of B cells with different receptors in the body.
Contrary to previous media reports, a new study led by Vanderbilt University Medical Center researchers finds that Medicare Part D prescription drug insurance plans largely favor generic drugs over brand-name counterparts.
New research has revealed a surprise twist in the symbiotic relationship between a type of salamander and the alga that lives inside its eggs. A new paper in Frontiers in Microbiology reports that the eggs compete with the algae to assimilate carbon from their surroundings - a finding that could inform similar processes in the dark ocean.
A new analysis of sandstones from Antarctica indicates there may be important links between the generation of mountain belts and major transitions in Earth's atmosphere and oceans.
A team of researchers analyzed the chemistry of tiny zircon grains commonly found in the Earth's continental rock record to determine their ages and chemical compositions. The team included scientists from the University of Wisconsin Oshkosh, Michigan Technological University and ETH Zurich in Switzerland.
Tropical cyclones, also known as typhoons, wreak havoc in Asia and the Pacific. The storms can be deadly -- in 2013, Typhoon Haiyan, the strongest ever recorded, was responsible for 6,340 deaths -- and cost billions in damages. Current forecast models can only predict these storms 10 days in advance, at most, and they cannot precisely predict how intense the storms will become.
Scientists at Sanford Burnham Prebys Medical Discovery Institute have uncovered a novel drug target, a protein called PPP1R1B, that stops the deadly spread of pancreatic cancer, called metastasis, when inhibited in mice. Published in Gastroenterology, the findings are a first step toward a potential treatment for one of the deadliest cancers known today.
Researchers from University of Mannheim and University of Texas - Austin published a new paper in the Journal of Marketing that examines the nature and effectiveness of marketing excellence as a business strategy. The study addresses two fundamental questions: How do managers understand and exercise marketing excellence? and How do investors evaluate marketing excellence?
The study, forthcoming in the Journal of Marketing, is titled "Marketing Excellence: Nature, Measurement, and Investor Valuations" and is authored by Christian Homburg, Marcus Theel, and Sebastian Hohenberg.
Researchers from Esade, University of St. Gallen, HEC Paris, and Columbia University published a new paper in the Journal of Marketing that explores the conundrum faced by firms that want to reduce their impact on the climate: Green products and their popularity with consumers can lead to an increase in sales and, with it, an increased carbon footprint for the organization as a whole.
WEST LAFAYETTE, Ind. - Dust explosions can be among the most dangerous and costly workplace incidents. Dust builds up in agricultural, powder-handling or manufacturing settings, causing hazards to employees and posing the risk of exploding.
Researchers at Purdue University have developed an image- and video-based application using OpenCV algorithms that detect explosible suspended dust concentration.
The Purdue team's work is published in the Journal of Loss Prevention in the Process Industries.
A new study which provides a global estimate of rock cover on the Earth's glaciers has revealed that the expanse of rock debris on glaciers, a factor that has been ignored in models of glacier melt and sea level rise, could be significant.
The Northumbria University study, which has been published in Nature Geoscience this week, is the first to manually verify the rock debris cover on every one of the Earth's glaciers.
A new study using satellite mapping technology reveals there are nearly 20% more emperor penguin colonies in Antarctica than was previously thought. The results provide an important benchmark for monitoring the impact of environmental change on the population of this iconic bird.
Researchers led by Columbia University’s International Research Institute for Climate and Society and the Pan-American Health Organization have developed a system to monitor and forecast the environmental suitability of transmission of Zika, dengue fever, chikungunya and other diseases carried by species of Aedes mosquitos in the U.S. and neighboring regions.
