The strongest Arctic cyclone ever observed struck in January 2022. A new analysis shows that while forecasts accurately predicted the massive storm, models seriously underestimated its effect on sea ice. Results suggest where forecast models for a changing Arctic Ocean could improve.

Differences in sharks' olfactory systems are of interest not only because of their reputation for having an incredible sense of smell but also because they have been around since before the dinosaurs. They managed to thrive in every known marine habitat for millions of years -- their sense of smell may have been key. A study is the first to quantify olfactory organ morphology by examining rosette...

An interdisciplinary team of researchers has developed a potential breakthrough in green aviation: a recipe for a net-zero fuel for planes that will pull carbon dioxide (CO2) out of the air.

Humans accomplish a phenomenal amount of tasks by combining pieces of information. We perceive objects by combining edges, categorize scenes by combining objects, interpret events by combining actions, and understand sentences by combining words. But researchers don't yet have a clear understanding of how the brain forms and maintains the meaning of the whole -- such as a sentence -- from its...

A scientific study exploring the appropriate interval for colorectal cancer screening via non-invasive multi-target stool DNA testing for individuals with average risk for the disease reported finding no colorectal cancers three years after an initial negative multi-target stool DNA test. These results suggest that at least a three-year interval between screenings using this method is clinically...

Two common drugs used by veterinarians to combat parasites may be effective against bed bugs, with one showing especially strong potential, according to a new study that examined the drugs in the context of controlling resurgent bed bug populations on poultry farms.

In 2018, researchers developed the 'Hikikomori Questionnaire (HQ-25)' to assess and identify hikikomori, a condition of pathological social withdrawal lasting more than six months. Now, the team has developed a new questionnaire they call HQ-25M in hopes of identifying the condition within just one month. Their initial analysis showed validation of the questionnaire as a possible tool for early...

Scientists have demonstrated a new technique, modeled after a metabolic process found in some bacteria, to convert carbon dioxide into solar fuels through artificial photosynthesis.

At the end of a bad day, how do you feel about yourself? The answer could indicate not only how your self-perception formed, but also how it renews, according to experimental results.

An initiative improves the timeliness of treatment for women with severe pregnancy-related hypertension, one of the leading causes of pregnancy-related death.

Microscopic image data is key to developing low-power, high-speed electronic devices. However, the complex interactions in nanoscale magnetic materials are difficult to understand. A research group has now realized a new functional design theory called 'extended Landau free energy model' that combines topology and AI with free energy to automate the interpretation of the microscopic image. This...

Researchers found that across the U.S., anal cancer incidence and mortality rates increased 1.5-fold in men and women over 50 years old. However, the most prominent increase -- more than two-fold -- occurred among people over 50 years of age living in the Midwestern and Southeastern states.

A new study points to introners, one of several proposed mechanisms for the creation of introns, as an explanation for the origins of most introns across species.

Canada geese collide with aircraft, intimidate unassuming joggers, and leave lawns and sidewalks spattered with prodigious piles of feces. They're widely considered nuisance birds, and municipalities invest considerable time and money harassing geese to relocate the feisty flocks. But new research shows standard goose harassment efforts aren't effective, especially in winter when birds should be...

Have humans wreaked too much havoc on marine life to halt damage? A new analysis challenges the idea that ocean ecosystems have barely changed over millions of years, pointing scientists down a new path on conservation efforts and policy.

Researchers identify the PKC-alpha enzyme as a promising therapeutic target in Alzheimer's disease; a mutation that increases its activity led to biochemical, cellular and cognitive impairments in mice.

A new study has identified a less invasive way to treat a subset of head and neck cancers that could potentially change the standard of care for patients. Combining radiation and immunotherapy primes patients for more successful surgeries, better responses to treatment and better quality of life.

Researchers have found that boron arsenide, which has already been viewed as a highly promising material for heat management and advanced electronics, also has a unique property. After reaching an extremely high pressure that is hundreds of times greater than the pressure found at the bottom of the ocean, boron arsenide's thermal conductivity actually begins to decrease. The results suggest that...

Adding additional salt to foods at a lower frequency is associated with a reduced risk of heart disease, heart failure and ischemic heart disease, according to a new study.

Combining machine learning with multimodal electrochemical sensing can significantly improve the analytical performance of biosensors, according to new findings.

The Sox9 gene is upregulated in the absence of sex-determining Y chromosome and Sry gene in Amami spiny rat.

A new study compiles data on more than 3,000 species to show how climate and geologic changes across Asia over the last 66 million years have shaped the evolution of the continent's mammals.

A new study shows how soon after a storm phosphorus 'loading' sparks algae explosions, but also describes the many other factors that weigh on when and whether the lake reaches a tipping point.

Researchers have developed a new strategy to help build materials with unique optical, magnetic, electronic and catalytic properties. These pinwheel-shaped structures self-assemble from nanoparticles and exhibit a characteristic called chirality -- one of nature's strategies to build complexity into structures at all scales, from molecules to galaxies.
