Researchers offer approaches for the sustainable expansion of the U.S. seafood industry
The "Executive Order on Promoting American Seafood Competitiveness and Economic Growth," issued by the Trump administration in May 2020, lays out a plan to expand the U.S. seafood industry, especially aquaculture, and enhance American seafood competitiveness in the global market.
New discovery sheds light on the mysterious family life of notorious sabre-toothed tiger
New research indicates adolescent offspring of the menacing saber-toothed predator, Smilodon fatalis, were more momma's cubs than independent warriors.
Emotionally appealing ads may not always help consumer memory
In almost all successful advertising campaigns, an appeal to emotion sparks a call-to-action that motivates viewers to become consumers. But according to research from a University of Illinois Urbana-Champaign expert who studies consumer information-processing and memory, emotionally arousing advertisements may not always help improve consumers' immediate memory.
Researchers propose a framework for evaluating the impacts of climate change on California's water and energy systems
As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand will intensify. But water and energy are inextricably linked. For instance, nearly a fifth of California's energy goes toward water-related activities, while more than a tenth of the state's electricity comes from hydropower. As society tries to adapt to one challenge, it needs to ensure it...
Energy sorghum may combine best of annual, perennial bioenergy crops
Large perennial grasses like miscanthus are a primary target for use as bioenergy crops because of their sustainability advantages, but they take several years to establish and aren't ideal for crop rotation. Maize and other annual crops are easier to manage with traditional farming but are tougher on the environment.
Insights into the Yellowstone hotspot
The Yellowstone hotspot is well known for generating supereruptions in the geologic past that are far more explosive than historic examples. The origin and sustained longevity of the hotspot is less understood but is focused on two competing models, where the ascent of hot mantle is derived from either a deep-seated mantle plume or a shallow mantle source.
Research confirms increase in river flooding and droughts in U.S., Canada
The number of "extreme streamflow" events observed in river systems have increased significantly across the United States and Canada over the last century, according to a study from Dartmouth College.
Winds and jet streams found on the closest brown dwarf
A University of Arizona-led research team has found bands and stripes on the brown dwarf closest to Earth, hinting at the processes churning the brown dwarf's atmosphere from within.
Space Station, Cygnus test technology for 5G communications, other benefits
A Northrop Grumman Cygnus supply craft carried a load of new scientific experiments to the International Space Station in early October. That is only one of the jobs the craft has, though. Once it undocks from the station Cygnus will continue operations by hosting a two-week test of emerging technologies known as SharkSat.
Keeping sperm cells on track
An essential component of every eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are antenna-like structures that protrude from most of the cells in our body, contain many microtubules. An example of flagell is the sperm tail, which is essential for male fertility and thus for sexual...
Patterns in primordial germ cell migration
Whenever an organism develops and forms organs, a tumor creates metastases or the immune system becomes active in inflammation, cells migrate within the body. As they do, they interact with surrounding tissues which influence their function. The migrating cells react to biochemical signals, as well as to biophysical properties of their environment, for example whether a tissue is soft or stiff....
Researchers question fundamental study on the Kondo effect
The Kondo effect influences the electrical resistance of metals at low temperatures and generates complex electronic and magnetic orders. Novel concepts for data storage and processing, such as using quantum dots, are based on this. In 1998, researchers from the United States published spectroscopic studies on the Kondo effect using scanning tunneling microscopy, which are considered...
Delivering the news with humor makes young adults more likely to remember and share
In the early decades of televised news, Americans turned to the stern faces of newsmen like Walter Cronkite, Tom Brokaw, and Dan Rather as trusted sources for news of the important events in America and around the world, delivered with gravitas and measured voices. The rise of comedy-news programs, helmed by the likes of Jon Stewart, Stephen Colbert, John Oliver, Trevor Noah, and Samantha Bee,...
For the right employees, even standard information technology can spur creativity
In a money-saving revelation for organizations inclined to invest in specialized information technology to support the process of idea generation, new research suggests that even non-specialized, everyday organizational IT can encourage employees' creativity.
Simple bioreactor makes 'gut check' more practical
Rice University and Baylor College of Medicine researchers have found a way to mimic conditions in intestines, giving them a mechanical model for the real-time growth of bacterial infections.
New challenges for wolf conservation
People view the wolf as either a threatening predator or a sign of a healthy natural habitat. Many proponents of nature and animal conservation welcome the spread of wolf populations in Germany. By contrast, farmers who graze herds directly impacted by the wolves' return are more critical.
High-flux table-top source for femtosecond hard X-ray pulses
Femtosecond hard X-ray pulses are an important tool for unraveling structure changes of condensed matter on atomic length and time scales. A novel laser-driven X-ray source provides femtosecond copper Kα pulses at a 1 kHz repetition rate with an unprecedented flux of some 1012 X-ray photons per second.
Spain surprised and delighted by rare snowfall
Heavy snow was falling across parts of Spain on Thursday which could cover up to half of the country in the coming days, forecasters said on Thursday
'Hail to the queen': Saving the Caribbean queen conch
With an estimated lifespan between 25 to 40 years, the queen conch (Strombus gigas) is a prized delicacy long harvested for food and is revered for its beautiful shell. Second only to the spiny lobster, it is one of the most important benthic fisheries in the Caribbean region. Unfortunately, the species faces a challenge of survival: how to endure and thrive, as populations are in a steady state...
Researchers synthesize bio-based Methylcyclopentadiene with 3-Methylcyclopent-2-enone
Methylcyclopentadiene (MCPD) is an important monomer in the production of RJ-4 fuel, a high-energy-density rocket fuel, and various valuable products.
Image: The sun in 2020
These 366 images of the sun were made by ESA's Proba-2 satellite in 2020.
Research on Japanese Izu Islands finds rising lizard temperatures may change predator-prey relationship with snakes
In a study spanning four decades, researchers from the University of Hong Kong's Research Division for Ecology & Biodiversity (HKU) in the Faculty of Science, and Toho University's Department of Biology (Toho), Japan, have discovered that predation by snakes is pushing lizards to be active at warmer body temperatures on islands where snakes are present, in comparison to islands free from snakes....
Israeli researchers discover new bee species
There is no overestimating the importance of pollinators in our world today. While crop pollination relies mainly on managed colonies of the domesticated honey bee (Apis mellifera), wild, unmanaged pollinators were found to be highly effective, often critical contributors to pollination services in natural and agricultural systems. Among these wild pollinators, native bees are the most important...
Why have so few Milky Way supernovae been observed over the last millennium?
Our galaxy hosts supernovae explosions a few times every century, and yet it's been hundreds of years since the last observable one. New research explains why: It's a combination of dust, distance and dumb luck.
Where antibiotic resistance comes from
By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.
