Scientists discover how immune response to TB differs in adults and newborn babies

The immune response to tuberculosis (TB) differs in adults and newborn babies due to the way immune cells use energy to kick into gear in a bid to kill the bacteria. This fresh discovery - just published in leading journal, Frontiers in Immunology - offers hope for improving treatments for what remains a deadly disease.

Researchers use science to take the guesswork out of cheese manufacturing

Making cheese leaves a lot to chance as a batch could be ripened for months or even years before a problem is discovered, which could send a prized batch of cheddar to be sold off cheap as an ingredient for processed cheese.

Oxidation processes play major role in the atmosphere and in combustion

Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via other reaction pathways than previously thought.

New research on mitochondrial function can play significant part in serious disease

Disorders of the cells' energy supply can cause a number of serious diseases, but also seem to be connected to aging.

“Food inks” could help preserve nutrition and flavor of fresh, frozen vegetables

Scientists have created a novel method in which fresh and frozen vegetables are used to produce “food inks.”

Researchers report a potential cancer drug that targets mitochondrial function

A newly developed compound starves cancer cells by attacking their "power plants" - the so-called mitochondria. The new compound prevents the genetic information within mitochondria from being read.

ECSIT protein can shed light on the origin of Alzheimer's disease

Researchers have found how a protein governs the behavior of proteins associated with the activity in mitochondria, which is impacted in Alzheimer's disease.

Previously uncharacterized protein regulates mitochondrial NAD transporter

For their growth, cells need various nutrients and vitamins. So-called solute carriers (SLC), proteins that can transport such substances across the boundaries of cellular membranes, play a central role in metabolism.

Low levels of hydrogen peroxide can slow down cell aging

High levels of reactive oxygen species, called oxidants, are detrimental to cells in all organisms and have been associated with ageing.

LipiDiDiet project shows positive effects of nutrient intervention in early Alzheimer’s disease

Trial participants who received a multinutrient formulation over an extended period of time showed a significantly less rapid deterioration in cognitive performance than the patients in a control group, who received only a placebo.

Scientists identify physiological mechanism that maintains regenerative capacity of muscle stem cells

Researchers at UPF, the National Centre for Cardiovascular Research, ICREA and Ciberned have identified a physiological mechanism that maintains the regenerative capacity of muscle stem cells, and surprisingly resists the passage of time far more than expected, until geriatric age.

Researchers use digital endocasts technique to reconstruct surface morphology of canine brains

Based on digital endocranial cast models the canine brain does not increase proportionally with body size. Researchers at ELTE Eötvös Loránd and Kaposvár University in Hungary reconstructed the surface morphology of 28 canine brains, including various dog breeds, wolves, coyotes, and jackals.

Researchers use multiple techniques to understand the effect of aging in humans

Humans’ hair becomes grey, their strength diminishes, and a host of age-related diseases represent what is occurring both at the molecular and cellular levels.

Fine-tuning stem cell metabolism prevents hair loss

A team of researchers have discovered a mechanism that prevents hair loss: hair follicle stem cells.

Epigenetics key to daily production of 10 billion blood cells without mistakes

Just one in 2,000 bone marrow cells are hematopoietic stem cells (HSC), but these are the source of the ten billion blood cells humans make every day.

Novel genetic measure could improve screening for osteoporosis

An international team of scientists has developed a novel genetic measure that could dramatically improve how doctors assess the risk of sustaining a fracture due to osteoporosis or fragility.

Study: High levels of iron in the blood can prevent age-related damage

Genes linked to ageing that could help explain why some people age at different rates to others has been identified by scientists.

A fine balance between maintaining immunity and longevity

As we age, the immune system gradually becomes impaired. One aspect of this impairment is chronic inflammation in the elderly, which means that the immune system is constantly active and sends out inflammatory substances.

Animal proteins more effective than plant proteins in building aging muscles

On a gram for gram basis, animal proteins are more effective than plant proteins in supporting the maintenance of skeletal muscle mass with advancing age, shows research presented this week at The Physiological Society's virtual early career conference Future Physiology 2020.

Researchers discover receptor that regulates aging effects in mice

Increasing abdominal girth and shrinking muscles are two common side effects of aging. Researchers at the University of Bonn have discovered a receptor in mice that regulates both effects.
