In an effort to fight the millions of tons of marine litter floating in the ocean, Florida State University researchers have developed a new virtual tool to track this debris.
Their work, which was published in Frontiers in Marine Science, will help provide answers to help monitor and deal with the problem of marine litter.

Researchers have long noted that readers with dyslexia employ eye movements that are significantly different from non-dyslexics. While these movements have been studied in small sample sizes in the past, a new paper written by Concordia researchers and published in the Nature journal Scientific Reports looks at a much larger group.
New interfacial superconductor has novel properties that raise new fundamental questions and might be useful for quantum information processing or quantum sensing.
Interfaces in solids form the basis for much of modern technology. For example, transistors found in all our electronic devices work by controlling the electrons at interfaces of semiconductors. More broadly, the interface between any two materials can have unique properties that are dramatically different from those found within either material separately, setting the stage for new discoveries.
The COVID-19 vaccine isn't having any trouble attracting suitors.
But there's another, older model that's been mostly ignored by the young men of America: the HPV vaccine.
Using data from the 2010-2018 National Health Interview Surveys, Michigan Medicine researchers found that just 16% of men who were 18 to 21 years old had received at least one dose of the HPV vaccine at any age. In comparison, 42% of women in the same age bracket had gotten at least one shot of the vaccine.
It's easy to think that more nutrients -- the stuff life needs to grow and thrive -- would foster more vibrant ecosystems. Yet nutrient pollution has in fact wrought havoc on marine systems, contributing to harmful algae blooms, worse water quality and oxygen-poor dead zones.
The legend of the "kraken" has captivated humans for millennia. Stories of deep-sea squid dragging sailors and even entire ships to their doom can be found in everything from ancient Greek mythology to modern-day movie blockbusters. It is therefore ironic that the species that inspired these stories, the giant squid Architeuthis dux, is camera-shy. In fact, filming this species in the wild has proven an insurmountable challenge for countless scientists, explorers, and filmmakers. To date, only one scientist, Dr.
New research from the University of Surrey has shown that silicon could be one of the most powerful materials for photonic informational manipulation - opening up new possibilities for the production of lasers and displays.
While computer chips' extraordinary success has confirmed silicon as the prime material for electronic information control, silicon has a reputation as a poor choice for photonics; there are no commercially available silicon light-emitting diodes, lasers or displays.
A promising new concept published by an interdisciplinary research team in "Proceedings of the National Academy of Sciences" (PNAS) paves the way for major advances in the field of magnetic resonance imaging (MRI). Their new technique could significantly simplify hyperpolarized MRI, which developed around 20 years ago for observing metabolic processes in the body. The proposal involves the hyperpolarization of the metabolic product fumarate using parahydrogen and the subsequent purification of the metabolite.
Isaac Newton may have met his match.
For centuries, engineers have relied on physical laws -- developed by Newton and others -- to understand the stresses and strains on the materials they work with. But solving those equations can be a computational slog, especially for complex materials.
Over recent decades, community-based environmental monitoring (often called "citizen science") has exploded in popularity, aided both by smartphones and rapid gains in computing power that make the analysis of large data sets far easier.
Researchers at the National Food Institute have come up with a solution that can help combat both food loss and food waste: They have generated a natural lactic acid bacterium, which secretes the antimicrobial peptide nisin, when grown on dairy waste.
Nisin is a food-grade preservative, which can extend the shelf life of foods, and thus can be used to reduce food waste. The discovery also makes it possible to better utilize the large quantities of whey generated when cheese is made.
Computer scientists often encounter problems relevant to real-life scenarios. For instance, "multiagent problems," a category characterized by multi-stage decision-making by multiple decision makers or "agents," has relevant applications in search-and-rescue missions, firefighting, and emergency response.
CHARGE syndrome is a rare genetic disorder affecting about 1 in 10,000 newborns. It can lead to neurological and behavioural disorders for which no treatment is currently available. Dr. Kessen Patten and his team, from the Institut national de la recherche scientifique (INRS) have just discovered a compound that could alleviate these symptoms.
Under normal, healthy circulatory conditions, the von Willebrand Factor (vWF) keeps to itself. The large and mysterious glycoprotein moves through the blood, balled up tightly, its reaction sites unexposed. But when significant bleeding occurs, it springs into action, initiating the clotting process.
CHAMPAIGN, Ill. -- For more than a decade, ecologists have been warning of a downward trend in bumble bee populations across North America, with habitat destruction a primary culprit in those losses. While efforts to preserve wild bees in the Midwest often focus on restoring native flowers to prairies, a new Illinois-based study finds evidence of a steady decline in the availability of springtime flowers in wooded landscapes.
