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.
An artificial intelligence system facilitates robots to perform independent scientific experiments—as many as 10,000/day—possibly taking a big step ahead in the speed of discovery in fields from medicine to environmental science to agriculture.
Proteins that work like air traffic controllers, controlling the flow of signals in and out of human cells, have been examined in unparalleled detail for the first time using modern microscope techniques.
We know that eating a healthy diet affects body weight, cholesterol levels, and heart health. A new study from the University of Illinois focuses on another component: the role of diet in supporting a healthy gastrointestinal microbiota.
Freiburg researchers discover a mechanism by which cancer cells escape the immune system.
A study found that a mitochondrial disease of newborns shows cancer-like changes in proliferating cells, causing tissues to age prematurely.
The USask research team uncovered a pair of genes involved in removing cells of toxins that build in the body and cause aging while working with small nematode worms called C. elegans. The researchers discovered that inactivating genes named CCF-1 and PAL-1 caused nematodes to die 50% faster than usual.
Researchers at the Van Andel Institute have created a new extraction protocol for RNA-seq and metabolomic analysis that provides a more comprehensive picture of cellular activity than either technique alone.
People's ability to regenerate bones declines with age and is further decreased by diseases such as osteoporosis.
CRISPR achieved scientific popularity for its capacity to quickly and precisely edit genes. At the core, however, CRISPR systems are immune systems that aid bacteria to safeguard themselves from viruses through targeting and abolishing viral RNA and DNA.
Lutz Grossmann is on a scientific quest to develop tasty, animal-free protein that has a minimal carbon footprint and is generated without the use of agricultural land, which is a common and more stressed source of the world’s food supply.
Researchers have discovered that if oxidative stress destroys protein factories known as ribosomes, repair crews may go in to assist in repairing the damage so that production may restart rapidly.
"One of the great mysteries of biology," says Eric Libby, former SFI Postdoctoral Fellow, now an associate professor at the Integrated Science Lab (IceLab), Umeå University in Sweden, "is eukaryogenesis, or how eukaryotes arose." Scientists consider this to be a period of major evolutionary transition, critical to our understanding of the history and evolution of life on Earth.
The human brain has a sweet tooth, burning through nearly one quarter of the body's sugar energy, or glucose, each day.
Approximately one to two milligrams of the trace element must be supplied daily through food and finally absorbed in the duodenum for a balanced iron metabolism.
In space, the bone density of both the human astronauts and rodent variety decreases. Scientists published this study on April 19th, 2023, in the journal Cell Reports. It says that alterations to the gut microbiomes of space travelers may be linked to this bone loss.
The human body naturally produces opioid-like substances, such as endorphins, which block the perception of pain and increase the feeling of well-being.
Numerous studies have revealed that weight loss in obese people leads to a reduction in whole-body energy expenditure.
The human body’s autophagy is triggered by fasting. The body activates the cells’ waste-removal mechanism and produces new energy. The brain plays a crucial part in this process, as researchers at the Max Planck Institute for Metabolism Research in Cologne recently found in mice.
Scientists from the University of California, Irvine, the University of Michigan and the University of Texas MD Anderson Cancer Center have made a significant contribution to the field of pancreatic cancer research.
A high-throughput single-cell single-mitochondrial genome sequencing technology known as iMiGseq has provided new insights into mutations of mitochondrial DNA (mtDNA) and offers a platform for assessing mtDNA editing strategies and genetic diagnosis of embryos prior to their implantation.
