Study explores link between shark nose shape, size and sensitivity of smell

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...

How the brain processes language

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...

New study provides evidence for three-year interval for multi-target stool DNA screening for those at average risk of colon cancer

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...

Toward early detection of pathological social withdrawal, Hikikomori

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...

Explainable AI-based physical theory for advanced materials design

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...

Canada geese beat humans in longstanding territory battle

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...

Research unearths obscure heat transfer behaviors

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...
