The study identified 524 human milk proteins and 518 in macaque milk, revealing 88 common proteins at different levels. Human milk contains higher levels of proteins aiding fat digestion and increasing iron absorption.
Scientists use advanced omics technologies to analyze the effects of substances on human cells, revealing potential health risks at very low concentrations. The study identifies changes in protein patterns and metabolism at non-toxic levels, which could inform the development of new risk assessment methods.
University of Illinois scientists have engineered a 'jailbreaking' yeast that increases wine's health benefits and reduces toxic byproducts. The new technology allows for precise metabolic engineering, enabling the addition of bioactive compounds from other foods and improving malolactic fermentation.
A recent study has identified a group of gene variants that may contribute to sporadic motor neurone disease, a devastating condition affecting thousands of Australians. Researchers sequenced the protein-coding genes of 44 MND-affected individuals and their parents, finding rare genetic changes in two-fifths of cases.
A study published in Nature Reviews Immunology reveals a 'window of vulnerability' for sexually transmitted infections (STIs) to infect the female reproductive tract. The researchers found that hormonal changes during the menstrual cycle create an optimal environment for implantation, which also increases susceptibility to STIs.
