Simple method for selective bioconjugation of native proteins
Irradiating formamide with meteorite dust can lead to synthesis of prebiotic compounds
New mitochondrially-derived peptides show what they can do
Biological safety lock for genetically modified organisms
The creation of genetically modified and entirely synthetic organisms continues to generate excitement as well as worry.
Defying textbook science, study finds new role for proteins
Open any introductory biology textbook and one of the first things you'll learn is that our DNA spells out the instructions for making proteins, tiny machines that do much of the work in our body's cells. ...
Interstellar molecules are branching out: Detection of iso-propyl cyanide with ALMA
Scientists from the Max Planck Institute for Radio Astronomy, Cornell University, and the University of Cologne have for the first time detected a carbon-bearing molecule with a "branched" structure in interstellar ...
New study revisits Miller-Urey experiment at the quantum level
For the first time, researchers have reproduced the results of the Miller-Urey experiment in a computer simulation, yielding new insight into the effect of electricity on the formation of life's building ...
Stanley Miller's forgotten experiments, analyzed
Stanley Miller, the chemist whose landmark experiment published in 1953 showed how some of the molecules of life could have formed on a young Earth, left behind boxes of experimental samples that he never ...
Design of self-assembling protein nanomachines starts to click
(Phys.org) —A route for constructing protein nanomachines engineered for specific applications may be closer to reality.
Amino acid fingerprints revealed in new study
Some three billion base pairs make up the human genome—the floor plan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply ...
Researchers reverse a liver disorder in mice by correcting a mutated gene
Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.
Chemists devise a new way to manufacture peptide drugs, which hold promise for treating many diseases
Small protein fragments, also called peptides, are promising as drugs because they can be designed for very specific functions inside living cells. Insulin and the HIV drug Fuzeon are some of the earliest ...
Study shows short peptides can self-assemble into catalysts
Better RNA interference, inspired by nature: New nanoparticles offer best-ever gene silencing
Inspired by tiny particles that carry cholesterol through the body, MIT chemical engineers have designed nanoparticles that can deliver snippets of genetic material that turn off disease-causing genes.
