Dad Plays Role in His Infant's Microbiome

Dads appear to make a small but important contribution to a newborn baby's gut health, a new study discovers.

Many microbes found in babies throughout their first year of life originate in the father rather than the mother, researchers report June 12 in the journal Cell Host & Microbe.

Space Travel Can Upset Human Immune Systems

Astronauts orbiting the Earth tend to suffer from immune system problems such as infections and the reactivation of dormant viruses, even on short-term space flights.

That appears to be because a lack of gravity causes the immune system to go awry during space travel, a new study has found.

Immune cells appear to grow differently in weightless conditions, affecting their ability to ...

Even a Small Urban Garden Can Boost Your Microbiome

A small urban garden can contribute to your health, especially if the garden contains rich soil, a new study shows.

A one-month indoor gardening period increased the bacterial diversity of participants' skin and appeared to improve their response to inflammation, researchers found.

Growing, harvesting and consuming food produced in an urban garden every day could help city dwellers ...

Researchers Find New Way to Curb Asthma Attacks

A protein that shuts down immune cells in the lungs could be key to a new treatment for asthma attacks, a new report says.

The naturally occurring protein, called Piezo1, prevents a type of immune cell called type 2 innate lymphoid cells (ILC2s) from becoming hyperactivated by allergens.

Even Slight Rise in One Gut Microbe Might Keep You Out of the Hospital

Even a slight rise in a specific type of beneficial gut bacteria can help people ward off serious infections, a new study reports.

For every 10% increase in butyrate-producing bacteria in a patient's gut, their risk of hospitalization for infection drops between 14% and 25%, researchers are scheduled to report at a major European medical meeting next month.

    Women Are More Prone to Autoimmune Disorders Than Men, and Scientists May Know Why

    Women are much more prone than men to develop autoimmune diseases like rheumatoid arthritis, multiple sclerosis and lupus.

    Now, researchers have come up with a potential explanation for that -- one that's rooted in genes that drive a person's gender.

    The female body has a complex means by which it handles the additional X chromosome, and it appears this process also renders some wom...

    Study Looks at COVID Threat to Folks With Weakened Immune Systems

    It's long been known that people with immune deficiencies are at increased risk for severe COVID.

    Over Half of People With Autoimmune Conditions Suffer Depression, Anxiety

    More than half of all patients with autoimmune diseases also suffer from depression and anxiety -- but most are never asked about their mental health, a new study finds.

    Surveying more than 1,800 patients, British researchers found more than half rarely or never reported their mental health symptoms to their doctor. This could mean the range of mental health and neurological symptoms is ...

    Spinal Cord Injury Could Harm Immune System

    A severe spinal cord injury is traumatic enough, but new research now shows that trauma can trigger an immune deficiency that puts patients at risk for developing life-threatening infections.
