When dairy cows are fed diets with reduced protein concentrations -- aimed at decreased environmental nitrogen pollution from their manure such as nitrate leaching, nutrient-laden run-off and ammonia volatilization -- their milk production…

Higher levels of vitamin B-related amino acids may be linked to the risk of dementia associated with a certain type of air pollutants called particulate matter, according to a study published in the July 19, 2023, online issue of…

Scientists perform computational simulations for biological molecules detected in meteorites to clarify the origin of life on Earth. All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying…

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. pN-Phe has been used by other research groups to…

Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, the early sun was formed, with a large…

Approximately half of people with type 1 or type 2 diabetes experience peripheral neuropathy -- weakness, numbness, and pain, primarily in the hands and feet. The condition occurs when high levels of sugar circulating in the blood damage…

Life depends on the precise functioning of several proteins synthesized in cells by ribosomes. This diverse set of proteins, known as a proteome, is maintained by the robust translation elongation of amino acid sequences taking place in the…

Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by a vast ocean. Over the course of millions of years, in that primordial soup, life emerged. Researchers have long theorized how…

Ever since their development in the late 19th century, Schiff bases have been a popular group of organic compounds, owing to their wide variety of desirable properties. The presence of both nitrogen and oxygen in their structure makes them…

The asteroid samples brought back by Japan’s Hayabusa2 space probe contained a total of 23 types of amino acids. These amino acids are building blocks of proteins, which are essential to life. The studies published in journal Science and…
