Protein synthesis and chance: A 'stochastic' model of protein synthesis
In the process of protein synthesis there is a "stochastic" component, i.e., involving random chance, which influences the time the process takes. This aspect has been investigated by two research scientists ...
Researchers find changes to protein SirT1
Researchers find changes to protein SirT1 can prevent excess metabolic stress associated with obesity, diabetes and aging.
Probing hydrogen catalyst assembly
Biochemical reactions sometimes have to handle dangerous things in a safe way. New work from researchers at UC Davis and Stanford University shows how cyanide and carbon monoxide are safely bound to an iron atom to construct ...
Mitochondrial ribosome revealed: Structure of large subunit deciphered
Researchers at the Swiss Federal Institute of Technology in Zurich have deciphered the structure of part of the ribosome found in mitochondria, the power plants of the cell. The scientists were able to benefit ...
Plants use 'unusual' microbial-like pathway to make essential amino acid
(Phys.org)—Purdue University researchers have discovered a microbial-like pathway in plants that produces phenylalanine, an amino acid that is a vital component of proteins in all living organisms.
Fight or flight and the evolution of pain
Hard wired into the survival mechanisms of all animals is the perception of pain. Different stimuli, such as heat or cold, foul odors, chemicals or a blunt blow can trigger pain receptors in the body that, in the blink of ...
Of lice and men (and chimps): Study tracks pace of molecular evolution
A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice. The researchers wanted to know whether evolution marches on at a steady pace in all creatures ...
Diet containing sufficient glutamate can aid both animals and humans
Glutamate, an abundant amino acid found in milk and meat, is getting a closer look by Dr. Guoyao Wu, a Texas A&M AgriLife Research scientist and distinguished professor in the department of animal science ...
Researchers use cells to expand nature's repertoire
Using a cell's own internal machinery, Yale researchers have produced proteins not found in nature that can cause cancer in mice, they report Dec. 16 in the Proceedings of the National Academy of Sciences.
Researchers find new recipe for novel proteins
(Phys.org) —Yale researchers have discovered a targeted way to make proteins not generally found in nature by expanding the information encrypted in the genetic code.
Study provides nutritional information on oilseed crop for use in pig diets
Long considered a weed in North America, Camelina sativa is increasingly valued as an oilseed crop.
Proteins' passing phases revealed
A new method to identify previously hidden details about the structures of proteins may speed the process of novel drug design, according to scientists at Rice University.
Tracking marine food sources
Oceans cover nearly 75 percent of the earth's surface and have always been an important source of food and resources. Yet overfishing, pollution and mismanagement threaten marine ecosystems and thus one of ...
How hummingbirds evolved to fly at high altitude
(Phys.org) —High up in the Andes, numerous species of hummingbirds are thriving despite low levels of oxygen.
