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.
What is the easiest way to know if a fruit fly is hungry? Ask a computer.
Researchers led by McMaster University professor Gregory Steinberg and postdoctoral research fellow Dongdong Wang have uncovered a key mechanism for promoting weight loss and maintaining the burning of calories during dieting.
Researchers at IRB Barcelona, the University of Barcelona (UB), VIMM, and the University of Padua unveil the key role of Mitofusin 2 cellular makeup in interconnecting organelles within cells.
Thor, the legendary Norse god from the mythological city of Asgard, is not alone. According to groundbreaking research published in the journal Nature, we humans -; along with eagles, starfish, daisies and every complex organism on Earth -; are, in a sense, Asgardians.
Eating fatty fish decreased the lipophilic index in people with impaired glucose metabolism or coronary heart disease, according to a new study from the University of Eastern Finland.
Recent research from the Earlham Institute identified candidate genes that might help fish endure warmer and saltier water, possibly providing a vital resource to drive breeding programs in freshwater aquaculture.
Human pluripotent stem cells were effectively transformed into purified pituitary cells, which aggregated into hormone-secreting organoids.
Pollen coat biosynthesis and transport are intricate processes involving compartmentalized biosynthesis, coordinated transport, and exact regulation between organelles and cell types, according to research conducted under the direction of Prof. Xiaoquan Qi at the Institute of Botany of the Chinese Academy of Sciences.
Microbes are by far the most important factor in determining how much carbon is stored in the soil, according to a new study with implications for mitigating climate change and improving soil health for agriculture and food production.
A climate feedback loop that can expedite climate change has been determined by scientists studying a group of extensive but often neglected microbes. However, it is not all bad news: this one shows an early warning signal.
A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 10, entitled, "Stress granules sequester Alzheimer's disease-associated gene transcripts and regulate disease-related neuronal proteostasis."
In crisis, the nucleus calls antioxidant enzymes to the rescue. The nucleus being metabolically active is a profound paradigm shift with implications for cancer research.
A population of unconventional white blood cells has recently captured the attention of immunologists and clinicians alike.
In this study, the researchers focused on para-nitro-L-phenylalanine (pN-Phe), a non-standard amino acid that is neither one of the twenty standard amino acids nor been observed in nature.
Antiretroviral cocktails can make human immunodeficiency virus, or HIV, undetectable and untransmittable, but both the virus and its treatment can also accelerate aging of bone and muscle.
Excess sugar hampers cells that renew the colon's lining in a mouse model of inflammatory bowel disease (IBD), according to a new study by University of Pittsburgh scientists.
A team of researchers have discovered that a mutation in a ribosomal protein found specifically in heart and skeletal muscle leads to impaired cardiac contractility in mice.
Enzymes are the molecule factories in biological cells. However, which basic molecular building blocks they use to assemble target molecules is often unknown and difficult to measure.
Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to research team leader Prof. Dr Alexis Maizel of the Centre for Organismal Studies at Heidelberg University.
The course of human history has been marked by complex patterns of migration, isolation, and admixture, the latter a term that refers to gene flow between individuals from different populations.
