Chemists claim to have solved riddle of how life began on Earth
Misuse of sustainability concept may lead to even more toxic chemical materials
Replacement of toxic chemical components by nontoxic and biocompatible natural analogs is one of the most popular approaches in sustainable projects. A study carried out at Zelinsky Institute of Organic Chemistry ...
The origins of handedness in life
Discovery demystifies origin of life chirality phenomenon
The origin of life is still a mystery with many unsolved puzzles. How were molecules created? How did they assemble into large structures? Among the conundrums, the "homochirality" phenomenon upon which amino ...
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. ...
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 ...
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.
Scientists discover cosmic factory for making building blocks of life
Scientists have discovered a 'cosmic factory' for producing the building blocks of life, amino acids, in research published today in the journal Nature Geoscience.
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 ...
Protein mimic shows promise as tissue engineering glue
Researchers have demonstrated the potential of a "synthetic protein mimic" to promote the adhesion of brain cells in a laboratory setting. This feat could help overcome a major challenge in nerve tissue engineering.
Biological safety lock for genetically modified organisms
The creation of genetically modified and entirely synthetic organisms continues to generate excitement as well as worry.
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.
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 ...
