Exercise Intervention Reduces Fat Accumulation Associated with Aging

Scientists have discovered that a type of fat accumulates as tissue ages and that this accumulation can be reversed through exercise.

Nutrient Deprivation Induces Embryonic Diapause in Hungry Mouse Mums

It's challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That's why many mammalian embryos can postpone their growth to get through periods of environmental stress and then re-enter development when conditions improve.

Study Reveals Early Development of Circadian Rhythms in Infant Gut Microbiomes

Infant gut microbiomes oscillate with a circadian rhythm, even when they are cultivated outside of the body.

New Theory Links Gene Length to Cellular Decline

A gene’s length may have more to do with aging than particular “aging genes.” Reduced expression of long genes may be the cause of many aging-related changes, according to researchers writing an opinion piece that was published in the journal Trends in Genetics on March 21st, 2023.

Unraveling the Role of Gene Length in Aging

Aging may be less about specific "aging genes" and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers in an opinion piece publishing March 21 in the journal Trends in Genetics.

New Research Highlights Gut's Role in Preventing Infections

According to a study published in the journal Nature, gut bacteria and a diet high in the amino acid tryptophan can protect against pathogenic E. coli, which can cause severe upset stomach, cramps, fever, intestinal bleeding, and renal failure.

Study Reveals Unique Bacterial Fingerprints and Their Impact on Health

The trillions of bacteria that call your body home -; collectively known as the microbiome -; appear to be unique to you, like a fingerprint.

Blood-Based Markers Unveil Secrets of Biological Aging

University of Pittsburgh researchers have uncovered blood-based markers linked with healthy and rapid aging, allowing them to predict a person's biological age -; how fast a person's cells and organs age regardless of their birthdate.

New Insights on Factors Influencing E. coli Contamination on Leafy Greens

Leafy green vegetables are important sources of dietary fiber and nutrients, but they can harbor harmful pathogens.

Unveiling the Mysteries of Life with Imageomics

According to one of the founders of the discipline, Imageomics, a burgeoning field of science, has made remarkable strides over the past year and stands at the precipice of significant breakthroughs in understanding life on Earth.

Mayo Clinic Researchers Analyze Zombie Cells to Explain Aging

With age, cells can experience senescence, a state where they stop growing but continue releasing inflammatory and tissue-degrading molecules.

Nutritional components guide intestinal stem cells and influence the aging process

The intestine's cellular balance is intricately maintained, and one factor that affects it is nutrition: eating a healthy diet increases the number of cells overall in the gut while fasting reduces it.

The Decline of Native Megaherbivore Species Since the Pleistocene

A meta-analysis of over 200 research globally found that the impact of large herbivores on plant abundance and variety is more dependent on their size and diet than on whether they are native to or imported into their host ecosystems.

Study Shows How Obesity Causes Mitochondrial Fragmentation in Fat Cells

The number of people with obesity has nearly tripled since 1975, resulting in a worldwide epidemic.

New Insights Into How Genetic Variation Affects Gene Expression

Chromatin accessibility and transcription factor binding are determined by genetic variation, according to a recent study from the University of Eastern Finland.

Honeybees Directly Provide Nutrients to Gut Bacteria

Bacteria have adapted to all terrestrial environments. Some have evolved to survive in the gut of animals, where they play an important role for their host; they provide energy by degrading indigestible food, they train and regulate the immune system, they protect against invasion by pathogenic bacteria, and they synthesize neuroactive molecules that regulate the behavior and cognition of their host.

Ancient DNA Reveals Reason for High Multiple Sclerosis and Alzheimer’s Rates in Europe

Researchers have created the world’s largest ancient human gene bank by analysing the bones and teeth of almost 5,000 humans who lived across western Europe and Asia up to 34,000 years ago.

B12-Producing Gut Bacteria Modulate Neurotransmitter Levels and Reduce Seizures in C. elegans

A new study published in Nature Cell Biology by Mark Alkema, PhD, professor of neurobiology, establishes an important molecular link between specific B12-producing bacteria in the gut of the roundworm C. elegans and the production of acetylcholine, a neurotransmitter important to memory and cognitive function.
