Researchers create first-ever map of a single animal’s early visual system

Neuroscientists at the Flatiron Institute in New York City and their colleagues have made a big breakthrough using one of the world’s smallest brains. Using an ion beam, an electron microscope and a lot of patience, the neuroscientists mapped out the entire early visual system — from the eyes that take in light to the neurons processing the information — for a parasitic wasp smaller than a grain of table salt. The feat marks the first time scientists have fully reconstructed such a system at the synaptic level from a single specimen of any animal species, the neuroscientists report ...

Intense lasers shine new light on the electron dynamics of liquids

An international team of researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg and ETH Zurich has now demonstrated that it is possible to probe electron dynamics in liquids using intense laser fields and to retrieve the electron mean free path – the average distance an electron can travel before colliding with another particle. They found that the mechanism by which liquids emit a particular light spectrum known as the high-harmonic spectrum is markedly different from the one in other phases of matter like gases and solids. The team’s findings open the door to a deeper understanding of ultrafast dynamics in liquids. Using ...

Study helps explain how COVID-19 heightens risk of heart attack and stroke

In some patients, infection with the pandemic virus SARS-CoV-2 can trigger a dangerous immune response in hardened fatty deposits (plaques) lining the heart’s largest blood vessels, a new study shows. The findings are based on the body’s immune system, which evolved to destroy invading microbes but also drives disease when triggered in the wrong context. Doing so brings on a set of responses termed inflammation, including swelling, which results as immune cells and signaling proteins home in on infection sites. ...

People who use alternative medicine favor risk and novelty, and distrust science

Over 40 per cent of Canadians have used at least one risk-associated alternative health-care treatment in the past 12 months, says a new UBC study published in PLOS One. The researchers explored alternative health-care therapies where the proven benefits do not justify the risks involved. They found that people who access these therapies tend to be wealthier, like novelty and taking risks, and are also more likely to distrust conventional medicine. The multidisciplinary study between UBC School of Nursing and the University of Alberta Health Law Institute involved a survey of 1,492 Canadians ages 16 and over ...

SARS-CoV-2 infects coronary arteries, increases plaque inflammation

SARS-CoV-2, the virus that causes COVID-19, can directly infect the arteries of the heart and cause the fatty plaque inside arteries to become highly inflamed, increasing the risk of heart attack and stroke, according to a study funded by the National Institutes of Health. The findings, published in the journal Nature Cardiovascular Research, may help explain why certain people who get COVID-19 have a greater chance of developing cardiovascular disease, or if they already have it, develop more heart-related complications. In the study, researchers focused on older people with fatty buildup, known as atherosclerotic plaque, who ...

Should older adults with fewer years to live keep getting cancer screenings? Poll explores attitudes

A majority of older adults disagree with the idea of using life expectancy as part of guidelines that say which patients should get cancer screenings such as mammograms and colonoscopies, a new poll finds. In all, 62% of people aged 50 to 80 said that national guidelines for stopping cancer-detecting tests in individual patients should not be based on how long that person might have left to live, according to new results from the University of Michigan National Poll on Healthy Aging. That goes against a trend in such guidelines, which national organizations develop based on medical evidence. Guidelines ...

Elk hoof disease likely causes systemic changes

PULLMAN, Wash. – Elk treponeme-associated hoof disease, previously thought to be limited to deformations in elks’ hooves, appears to create molecular changes throughout the animal’s system, according to epigenetic research from Washington State University. The findings, published in the journal Scientific Reports, also suggest those changes may be heritable. It remains to be seen though whether this means subsequent generations of elk may be more, or less, prone to catching the devastating disease that severely impairs the elk’s ability to find food and escape predators. “It’s not just the ...

Predicting condensate formation by cancer-associated fusion oncoproteins

(Memphis, Tenn – September 28, 2023) Many cancers are caused by fusion oncoproteins, molecules that aberrantly form when a rearrangement of DNA results in parts of two different proteins being expressed as one. Several fusion oncoproteins spontaneously form condensates inside cells that promote cancer development. New research by St. Jude Children’s Research Hospital established a method to study this biophysical process in cells, then used that information as a launchpad to predict the behavior of other fusion oncoproteins. The findings, which offer insight into ...

Child Development journal Q&A: Music intervention programs can enhance parent and baby language interactions

Previous research shows that conversational turns (interactive conversations) between parents and children are important for a child’s long-term language development and academic achievement and that these conversations can be enhanced via parent-coaching language interventions. The neural networks responsible for language develop rapidly even before a child can talk, making these interactive conversations especially important during infancy. Music is an engaging and social experience between parents and children that is often part of daily routines during infancy. Emerging literature also documents links between music experiences and child language outcomes. Researchers ...

New program helps improve toddlers’ self-control skills and healthy eating habits

Two of the best predictors of life-long health and well-being are early childhood self-control skills and healthy eating habits. A new program that teaches parents how to cook with their 2-year-olds is helping toddlers excel on both fronts. Doing things like stirring ingredients together without spilling and singing a song while something is in the microwave helps toddlers learn multiple important self-control skills, like paying attention, controlling their bodies, waiting patiently, and cooperating with their parents. Toddlers also get excited about being involved in the “grown-up” activity and are more likely to try the new foods they help make. Previous research has shown that ...
