Metabolism is the means by which the body derives energy and synthesizes the other molecules it needs from the fats, carbohydrates and proteins we eat as food, by enzymatic reactions helped by minerals and vitamins.
Plants regulate their growth and development using hormones, including a group called strigolactones that prevent excessive budding and branching.
Researchers at Université de Montréal and McGill University have discovered a new multi-enzyme complex that reprograms metabolism and overcomes “cellular senescence,” when aging cells stop dividing.
AD, the most frequent cause of dementia, affects an estimated 24 million people worldwide. With very limited treatment options, scientists are looking for ways to understand the disease better.
Researchers have presented a method for profiling tissue-specific secretory proteins in live mice. This method is expected to be applicable to various tissues or disease models for investigating biomarkers or therapeutic targets involved in disease progression.
A synthetic molecular code exhibits the potential of enhancing the response of certain cancer patients to immunotherapy treatments.
A new study by researchers from the Gwangju Institute of Science and Technology in the Republic of Korea has revealed the mechanism of DNA repair by enzymes exonuclease III and polymerase I by utilizing single molecule fluorescence resonance energy transfer (smFRET)-enabled dynamic observation.
Recent research suggests that a simple process could underlie the growth and self-replication of protocells—putative ancestors of modern living cells.
According to new research, an avocado a day can redistribute belly fat in women toward a healthier profile.
An international collaboration has discovered and transferred to elite wheat varieties a wild-grass chromosome segment that causes roots to secrete natural inhibitors of nitrification, offering a way to dial back on heavy fertilizer use for wheat and to reduce the crop's nitrogen leakage into waterways and air, while maintaining or raising its productivity and grain quality, says a new report in the Proceedings of the National Academy of Sciences of the United States of America.
A group of scientists combined their mastery to obtain a thorough understanding of the risks linked with cannabis exposure at the time of pregnancy.
The evolution of humans has given them a level of protection from the risk of cold temperature with the ability to generate heat from fat stored in the body.
A new inexpensive and high-throughput technique for profiling metabolic features using only one isogenic sample of cells has been devised by researchers.
Think of cells as tiny factories: within their walls they have both the machinery to make products such as proteins, and the mechanisms for maintenance to keep processes running smoothly.
Research has revealed higher cholesterol supply from astrocytes to neurons in the model of Alzheimer’s disease (AD) brains.
A group of scientists have identified a connection between the type of microbiome that recolonizes the gut after antibiotics and the lessened lifespan in mice.
Scientists from the University of Basel observed in experiments with mice that cells can self-heal and eradicate viruses.
A stress signal received by the heart from fat could help protect against cardiac damage induced by obesity, a new study led by UT Southwestern researchers suggests.
Time-restricted eating (TRE) is a dietary regimen in which eating is restricted to particular hours. It has received great attention in weight-loss circles.
A team of scientists at the University of Illinois Urbana-Champaign developed a bioprocess using engineered yeast that completely and efficiently converted plant matter consisting of acetate and xylose into high-value bioproducts.
Throughout development, life and the processes of aging, all human cells accumulate mutations, resulting in what is called mosaicism, a condition in which different cells in the same person have different DNA sequences or genetic makeup.
