Scientists discover a human receptor protein capable of identifying individual amino acids

Researchers have found that a human receptor protein can identify individual amino acids in just the similar way that bacteria do.

Protein appears key to the function and survival of brain cells most impacted by glaucoma

A ubiquitous protein called sigma 1 receptor, which is known to protect cells from stress, appears key to the function and survival of the neurons most impacted by glaucoma, scientists report.

Researchers identify protein switch that regulates enzymes in pathogens

Proteins are the “workhorses” of all living cells and are the chemical foundation of life.

Experts identify a potential new target for antimalarial development

A protein that plays an important biological role in the malaria-causing parasite has been discovered by an international research team.

Lifelong exercise may help counteract the deterioration of fat tissue function with age

Fat tissue plays an important role in human health. However, our fat tissue loses function as we age, which can lead to type 2 diabetes, obesity, cancer and other ailments.

Researchers engineer strains of nitrogen-fixing soil bacterium to produce ammonia

Researchers from Washington State University have engineered strains of the ubiquitous, nitrogen-fixing soil bacterium Azotobacter vinelandii to produce ammonia and excrete it at high concentrations, transferring it into crop plants in lieu of conventional chemical fertilizers.

New study deepens the understanding of microbial sulfur metabolism

The metabolism of sulfur compounds is among the most important microbial processes sustaining life in many anoxic environments where oxygen is not present.

MIT researchers create a new cerebrovasculature atlas

While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain.

NTU Singapore scientists design new method to generate sulfur pharmacophores

A key technical challenge in creating new sulfur-based medicines has been overcome by scientists at Nanyang Technological University, Singapore, leading to the prospect of many new therapeutic 'weapons' in the fight against disease and illness.

Mortality of newborns on ECMO linked with red blood cell transfusion volume

Newborns in respiratory failure who require the life-sustaining support of ECMO also require transfusion of red blood cells. But a new study indicates that the higher volume of these oxygen-carrying blood cells the babies receive, the higher their mortality rate.

Hemoglobin plays role as a chemosensory signal for mother mice to protect offspring

Biochemists in Japan were surprised to discover that the molecule hemoglobin in the blood works not only as an oxygen carrier, but when the blood is spilled as a result of aggression, accident or predator attack, the molecule also acts as a chemosensory signal -; a chemical stimulus picked up by the senses, namely smell in this case -; for lactating mother mice, prompting digging or rearing behavior in them to check the surrounding environment and keep their offspring safe.

Three proteins as potential new therapeutic targets in movement disorders

Three members of a family of proteins have been identified that are important to helping us fine tune the activity of brain chemicals which enable us to walk or stand at will, scientists report.

Cell culture environments are unstable and drive reproducibility crisis

Culture environments of different cell types growing in culture vessels or Petri dishes vary significantly from each other and from conditions in the living body, potentially driving the "reproducibility crisis" in biomedical research, according to a team of KAUST bioscientists.

Microorganisms “breathe” rocks through extracellular electron transfer, says study

Microbes may be tiny, yet they have a significant influence on the Earth’s habitability.

Scientists visualize protein machinery of respiration with unparalleled precision

Oxygen and sugar are the basis of life for animals, plants, fungi and many bacteria. The metabolic process called respiration makes it possible to convert food into energy for the cells.

Study offers insight into how activated protein C may protect aging patients from reperfusion injury

A University of South Florida Health (USF Health) preclinical study offers molecular insight into how activated protein C (APC) may improve aging patients' tolerance to reperfusion injury – a potentially adverse effect of treatment for ischemic heart disease.
