Gut Ecology

Researchers use old equations coupled with new methods to help decode the massively complex gut microbiome. For something that has evolved with us over millions of years, and remains part of our physiology over our entire lives, our gut microbiome, oddly, remains somewhat of a mystery. Comprised of trillions of […]

Mother roundworms have ultra-protective instincts

Talk about motherly instincts: Biologists at the University of Iowa have learned that female roundworms can alert their future offspring of dangers they will encounter when born, and the mothers pass on these warnings even before the offspring have been conceived. The study shows that a mother roundworm releases a chemical […]

Scientists generate millions of naïve human pluripotent stem cells, far more than have ever been produced

For decades, the enormous disease-curing potential of human stem cells has been thwarted by the inability to produce sufficient quantities of mature human cells in vivo — in a living organism. Now, a team led by University at Buffalo scientists has developed a method that dramatically ramps up the production […]

Pricey Protocol Not Proven to Prevent or Reverse Alzheimer’s, Says UCSF Neurologist

Promising Research May Have Been Sullied by Shoddy Science. A protocol comprising dietary supplements and lifestyle changes that claim to prevent or reverse Alzheimer’s disease and cognitive decline has drawn media fanfare and critical acclaim from health gurus and even physicians. But the endorsement of these claims is frequently based […]

Yale researchers discover how HIV hides from treatment

Even after successful antiretroviral therapy, HIV can hide dormant in a tiny number of immune system cells for decades and re-emerge to threaten the life of its host. Now Yale University researchers have discovered a molecular explanation for how the virus accomplishes this insidious trick, they report in the journal […]

Fasting plus vitamin C proves effective for hard-to-treat cancers

A USC study found that a combination of a fasting-mimicking diet plus vitamin C delayed tumor progression and even caused disease regression in mice. Scientists from USC and the IFOM Cancer Institute in Milan have found that a fasting-mimicking diet could be more effective at treating some types of cancer when […]

Colour of cells a 'thermometer' for molecular imbalance

An imbalance of unstable molecular species called ‘free radicals’ will change the colour of cells – and a new imaging technique could one day allow scientists to detect and decode this colour without needing to take samples from the body, a new study by UNSW Sydney researchers has found. The […]

First Epigenetic Study in 3D Human Cancer Cells

Frequently, promising cancer therapies fail when applied to patients in the real clinical setting. This occurs despite many of these new treatments demonstrating promising results at the preclinical stage in the lab. One explanation is that many of the tumor models used in early research phases are established cell lines […]

Our ability to focus may falter after eating one meal high in saturated fat

Fatty food may feel like a friend during these troubled times, but new research suggests that eating just one meal high in saturated fat can hinder our ability to concentrate – not great news for people whose diets have gone south while they’re working at home during the COVID-19 pandemic. […]

Could a drug combination prevent people with the eye disease uveitis lose their sight?

Two in 10,000 people are at risk of serious sight loss from a form of eye inflammation known as uveitis. A new clinical research study, led by the University of Bristol and University Hospitals Bristol and Weston NHS Foundation Trust (UHBW), will evaluate a drug combination treatment for the eye […]

Mice with patchy coats lay bare how stem cells endure

Whether we like it or not, our hair continually grows. Its regenerative powers reside deep inside each hair follicle, in a cluster of dividing stem cells—some of which will specialize and eventually give rise to new hair while others will produce new stem cells. Scientists have delineated numerous mechanisms that […]

Activating an Estrogen Receptor Can Stop Pancreatic Cancer Cells from Growing

Activating the G protein-coupled estrogen receptor (GPER) – a receptor found on the surface of many normal and cancer tissues – has been shown to stop pancreatic cancer from growing, but may also make tumors more visible to the immune system and thus more susceptible to modern immunotherapy. Researchers at […]

Potato power: Spuds serve high quality protein that’s good for women’s muscle

Researchers from McMaster University have found that the potato, primarily known as a starchy vegetable, can be a source of high-quality protein that helps to maintain muscle. The findings, reported in the journal Nutrients, highlight the potential benefits of what is considered a non-traditional source of protein, particularly as dietary […]
