Consistently exercising 2–3 times a week over the long term is linked to a lower current risk of insomnia as well as the ability to clock up the recommended 6–9 hours of shut-eye every night, suggests an international 10-year study published in the open access journal BMJ Open.

Regular exercise is associated with better overall health, and several studies have suggested that physical activity promotes better quality sleep and may improve symptoms of chronic insomnia, note the researchers.

But it’s not entirely clear how much gender, age, weight (BMI), overall fitness, general health, and exercise type contribute to this association, they add.

Nanomaterials manufacturing, 3D bioprinting, and astronaut eye health were the main research topics aboard the International Space Station on Friday. The Expedition 71 crew members also continued servicing spacesuits and conducted an emergency drill.

The SpaceX Dragon cargo spacecraft recently delivered to the orbital outpost a biotechnology study to demonstrate the in-space production of nanomaterials that mimic DNA. NASA Flight Engineers Jeanette Epps and Mike Barratt worked on the second portion of that experiment on Thursday mixing then treating the research samples for analysis. Epps began her day mixing solutions in the Life Science Glovebox to create specialized nanomaterials. During the afternoon, Barratt applied sound and light treatments to the samples then stowed them aboard Dragon for analysis back on Earth. Results may lead to advanced therapies for space-caused and Earthbound health conditions.

The duo partnered back together at the end of the day for eye scans using standard medical imaging gear found in an optometrist’s on Earth. Barratt operated the hardware with guidance from doctors on the ground peering into Epp’s eyes and examining her retina and optic nerve for the B Complex eye health investigation.

Study critiques the World Health Organization’s fungal priority pathogens list for not fully reflecting the global burden of fungal diseases, advocating for a revised list that considers regional disparities and elevates the priority of pathogens like Mucorales and Histoplasma spp. to better align with their impact on public health.

Cell and animal tests suggest two classes of common chemicals might play a role in neurological disease.

The child required a specific nutrient blend to optimize health and reduce kidney strain.

Prescription drugs helped a toddler born with a rare and chronic kidney disease receive a kidney transplant and escape the net of repeated dialysis sessions, all due to the efforts of his mother and the team of doctors.

The toddler, Dinero Motton, had been diagnosed with a lower urinary tract obstruction and enlarged bladder when he was still in his mother’s womb.

One of the largest threats to human health is obesity, but now researchers from the University of Aberdeen Rowett Institute have made an important discovery in how the brain controls food intake.

Obesity and being overweight have become the “new normal” in modern times and can lead to a multitude of health problems. We know that excess weight is primarily caused by eating more calories than the body needs; however, new research published in Current Biology has found a specific cluster of cells in the brain that control body weight.

How the brain controls hunger has not been fully defined. The researchers discovered a cluster of brain cells that can be harnessed to reduce food intake and body weight. One way they do this is by turning down cells that stimulate hunger.

There are trillions of microorganisms living in our gastrointestinal tract. So why doesn’t the immune system launch a massive response against all of those foreign microbes? Scientists have now provided new details about the process. The findings have been reported in Nature.

The gut microbiome has to maintain a careful balance, and promote the growth of healthy and beneficial organisms while tamping down the growth of potential pathogens. While scientists have not defined exactly what a healthy microbiome is made of, and it may differ from one person to another, we do know that when the balance in the microbial community of the gut is disrupted, health problems can arise.
