Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.

Phage protein study opens new path for future antibiotics

Drug-resistant bacteria are becoming more common worldwide, posing a major public health challenge. Addressing this problem requires finding new ways to eliminate bacteria, which in turn requires analyzing essential cellular processes that could serve as targets for future antibiotics.

Study reveals how astrocytes regulate brain blood flow and activity

What happens in our brains when we experience sensory stimulation? During everyday activities such as jogging, reading, or listening to music, sensory inputs activate neurons in specific brain regions.

Histone subvariant H3mm15 plays key role in sperm development

Researchers from Kyushu University have found that H3mm15, a histone H3.3 subvariant, contributes to normal sperm development in mice by helping regulate gene expression during spermatogenesis.

Single amino acid change alters Andes virus protein behavior

Mount Sinai researchers have identified a single amino acid difference between rodent- and human-derived Andes virus isolates that changes how a key viral protein behaves inside human cells.

Struggling with constipation? Two green kiwifruits a day may help

A narrative review of 33 publications found that consuming two fresh green kiwifruits daily for approximately four weeks can improve bowel movement frequency and gastrointestinal comfort in adults with functional constipation or constipation-predominant irritable bowel syndrome (IBS-C). Clinical studies reported broadly similar improvements with kiwifruit, psyllium, and prunes, although more research is needed to establish long-term benefits and differences between kiwifruit varieties.

Study uncovers translation control mechanisms driving tumor growth and therapy resistance

Decoding of messenger RNA (mRNA) occurs during translation, the vital cellular process that builds proteins. Errors in this process are known to lead to cancer growth.

Evolutionary changes in key enzyme help bacteria fine-tune protein synthesis

Evolutionary changes in key protein synthesis enzyme, isoleucyl-tRNA synthetase (IleRS), may help bacteria fine-tune how quickly proteins are made, report researchers from Institute of Science Tokyo, Japan; the University of Zagreb Faculty of Science, Croatia; and ETH Zürich, Switzerland.

New study identifies potential targets for KRAS-related treatment resistance

Decoding of messenger RNA (mRNA) occurs during translation, the vital cellular process that builds proteins. Errors in this process are known to lead to cancer growth.

Amino acid restores power to last-resort antibiotics

Worldwide, antibiotic resistance is associated with millions of deaths every year, and the World Health Organization warns that the number of resistant infections is rising.

Insights into enzyme selectivity open new pathways for pharmaceutical synthesis

Enzymes are the molecular tools of life. They accelerate chemical reactions and are able to distinguish very precisely between molecules that are similar to one another. The high selectivity of many enzymes is key to the production of important medicines such as penicillin and cyclosporine. But how did enzymes develop this ability to distinguish between similar chemical functionalities with such precision.

Ancient protein model shows early steps in energy metabolism

Researchers in Japan engineered ancestral nucleoside diphosphate kinase variants with restricted amino acid repertoires to explore alternative catalytic functions. One variant, Arc1-12KR, retained its protein fold despite lacking catalytic histidine and unexpectedly converted two ADP molecules into ATP and AMP. The findings reveal alternative catalytic potential in simplified proteins and offer clues to possible routes of energy metabolism during early protein evolution.

Low vitamin B12 is linked to heart disease. Supplements tell a different story

A narrative review published in Nutrition Journal examines how vitamin B12 deficiency may contribute to cardiovascular disease through elevated homocysteine, endothelial dysfunction, oxidative stress and altered methylation. The authors found that B12 supplementation has not consistently prevented heart attacks or cardiovascular deaths in clinical trials, although combined B-vitamin therapy may modestly reduce stroke risk, particularly in populations without folic acid fortification.

Semaglutide changes gut bacteria in rats beyond what eating less explains

Researchers compared semaglutide-treated male and female rats with pair-fed animals receiving the same amount and type of food to distinguish drug-associated microbiome changes from those linked to reduced eating. Semaglutide altered bacterial richness and community composition, with some changes absent from the pair-fed groups and uncertain consequences for health.

Taurine helps regulate inflammation linked to aging, Yale study finds

Sustained low-level inflammation is a hallmark of the aging process. The accumulating damage persistently activates the innate immune system-the body's first line of defense-leading to what is known as inflammaging, functional decline and chronic diseases of old age.

Does adding yeast to whey protein help muscle recovery after exercise?

The yeast-whey protein blend shows potential in aiding muscle recovery after exercise-induced damage, yet its effectiveness compared to whey alone is uncertain.

Ebola vaccine triggers cross reactive T cells against Bundibugyo ebolavirus

The ongoing Bundibugyo ebolavirus (BDBV) outbreak in the Democratic Republic of the Congo is the second-largest Ebolavirus outbreak globally, with more than 6,000 confirmed cases and a mortality rate of 48 percent.

From turmeric to fenugreek, scientists examine nature’s potential role in diabetes care

A narrative review examined how curcumin, honey, culinary spices, and traditional remedies may influence oxidative stress, inflammation, mitochondrial function, and insulin signaling in diabetes. Although experimental research and some clinical trials suggest potential metabolic benefits, the authors emphasize that larger, well-controlled studies are needed to establish their effectiveness and safety alongside conventional treatments.
