Genes in beans: Bean genome sequenced for improved nutrition

The faba bean genome, which at 13 billion bases is more than four times the size of the human genome, has been sequenced for the first time and is published in Nature. This is an extraordinary technical achievement and crucial ...

Metabolic protein explains how flies choose 'healthy' food

Many animals, including humans, have a preference for nutrient-balanced diets. Among all essential nutrients, multicellular organisms need to consume the building blocks of proteins, called amino acids, in order to build ...

How the body senses an essential amino acid

A new paper from Whitehead Institute researchers reveals how mice sense an essential amino acid called leucine, which many people get from eating fish, eggs, or nuts. Down the line, the work could inform research into creating ...

Coaxing jellyfish, flies and mice to regenerate body parts

Caltech researchers have discovered certain conditions that enable different laboratory animals to regenerate amputated appendages. Upon consuming a diet high in sugar and an essential amino acid, three different species—the ...

Gut hormone triggers craving for more proteins

A new study led by KAIST researchers using fruit flies reveals how protein deficiency in the diet triggers cross talk between the gut and brain to induce a desire to eat foods rich in proteins or essential amino acids. This ...
