Processed foods and effect on developing fetus' brain: Autism link?

Saleh Naser, Latifa Abdelli and UCF undergraduate research assistant Aseela Samsam have identified the molecular changes that happen when neural stem cells are exposed to high levels of an acid commonly found in processed foods.

Gut microbes eat our medication

Even more crucial are the reactions that happen after the plates are clean.

The brain consumes half of a child's energy -- and that could matter for weight gain: New paper proposes that variation in brain energy expenditure during childhood could be linked to obesity risk

In a new paper published in the journal Proceedings of the National Academy of Sciences (PNAS), "A hypothesis linking the energy demand of the brain to obesity risk," co-authors Christopher Kuzawa of Northwestern University and Clancy Blair of New York University School of Medicine, propose that variation in the energy

CRISPR baby mutation significantly increases mortality: Two copies of mutated CCR5 gene associated with lower survivability

The researchers scanned more than 400,000 genomes and associated health records contained in a British database, UK Biobank, and found that people who had two mutated copies of the gene had a significantly higher death rate between ages 41 and 78 than those with one or no copies. Previous

Ultimate destiny: How undifferentiated cells commit to their biological fate

This complexity, however, belies the fact that each of the trillions of highly specialized cells start out as a single primordial cell.

Brain anatomy links cognitive and perceptual symptoms in autism

Mental inflexibility is a hallmark symptom of autism spectrum disorder (ASD).This is best seen in restricted and repetitive behaviors, which are required for an ASD diagnosis..

Viruses found to use intricate 'treadmill' to move cargo across bacterial cells: State-of-the-art technologies reveal bacterial cells organized like human cells, offering insights for new phage therapies on untreatable infections

Now, using advanced technologies to explore the inner workings of bacteria in unprecedented detail, biologists at the University of California San Diego have discovered that in fact bacteria have more in common with sophisticated human cells than previously known. Publishing their work June 13 in the journal Cell, UC San

Two hours a week is key dose of nature for health and wellbeing

Research led by the University of Exeter, published in Scientific Reports and funded by NIHR, found that people who spend at least 120 minutes in nature a week are significantly more likely to report good health and higher psychological wellbeing than those who don't visit nature at all during an

New evidence links ultra-processed foods with a range of health risks: Policies that limit ultra-processed food intake are urgently needed, say researchers

The researchers say further work is needed to better understand these effects, and a direct (causal) link remains to be established, but they call for policies that promote consumption of fresh or minimally processed foods over highly processed foods. Ultra-processed foods include packaged baked goods and snacks, fizzy drinks, sugary

Translation of genes more complex than expected

From gene to protein Each cell in our body contains the same DNA, yet different cells, like brain cells or muscle cells, have different functions..

How old are your organs? To scientists' surprise, organs are a mix of young and old cells: Scientists discover cellular structures with extreme longevity, leading to insights for age-associated diseases

"We were quite surprised to find cellular structures that are essentially as old as the organism they reside in," says Salk Vice President, Chief Science Officer Martin Hetzer, senior author and professor. "This suggests even greater cellular complexity than we previously imagined and has intriguing implications for how we think

New study identifies molecular aging 'midlife crisis'

Claes Wahlestedt, M.D., Ph.D., professor of psychiatry and behavioral sciences and associate dean for therapeutic innovation at the University of Miami Miller School of Medicine, is senior author of a new study -- Longevity Related Molecular Pathways Are Subject to Midlife 'Switch' in Humans -- published today in

What Is Change Blindness & How It Affects You without Your Awareness

I was watching an episode of Air Crash Investigation the other day and investigators stated that the cause of a fatal aeroplane crash was change blindness.My ears pricked up.

Marineland Is Officially Exempt From Canada’s Ban On Whale & Dolphin Captivity

Canada recently passed a bill that bans the capture and captivity of whales and dolphins.
