Early-Earth cells modeled to show how first life forms might have packaged RNA
(Phys.org)—Researchers at Penn State University have developed a chemical model that mimics a possible step in the formation of cellular life on Earth four-billion years ago. Using large "macromolecules" ...
Researchers develop new technique for heterogenizing homogenous nano catalysts
(Phys.org)—Catalysts are substances that speed up the rates of chemical reactions without themselves being chemically changed. Industrial catalysts come in two main types - heterogeneous, in which the catalyst ...
Thermoelectric material is world's best at converting heat waste to electricity
Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input ...
Molecule reorganises itself for new functions
(Phys.org) -- The discovery of a synthetic molecule, made up of 60 simple components that are able to reorganise themselves to produce new functions, will lead to better understanding of nature's processes.
Graphene's behavior depends on where it sits
When you look at a gift-wrapped present, the basic properties of the wrapping paper say, its colors and texture are not generally changed by the nature of the gift inside.
Researchers explain how dye-based nanotubes can help harvest light's energy
Companies that make commercial solar cells are happy if they can achieve 20 percent efficiency when converting sunlight to electricity; an improvement of even 1 percent is seen as major progress. But nature, ...
New 3D printing process could lead to DIY drugstores
(Phys.org) -- A new 3D printing process developed at the University of Glasgow could revolutionise the way scientists, doctors and even the general public create chemical products.
Scientists discover a surprising new way that protons can move among molecules
When a proton the bare nucleus of a hydrogen atom transfers from one molecule to another, or moves within a molecule, the result is a hydrogen bond, in which the proton and another atom like ...
Scientists develop new class of small molecules through innovative chemistry
Inspired by natural products, scientists on the Florida campus of the Scripps Research Institute have created a new class of small molecules with the potential to serve as a rich foundation for drug discovery.
Quantum mechanical calculations reveal the hidden states of enzyme active sites
Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as "active" sites. But scientists lack basic information ...
New nanoscale protein container could lead to synthetic vaccines and medicine delivery method
UCLA biochemists have created the largest-ever protein that self-assembles into a molecular "cage." The research could lead to synthetic vaccines that protect people from the flu, HIV and other diseases.
Finding new ways to make drugs
Chemists have developed a revolutionary new way to manufacture natural chemicals and used it to assemble a scarce anti-inflammatory drug with potential to treat cancer and malaria.
Chemists develop 'nanoreactor' for discovering new chemical reactions
(Phys.org) —In 1952, the famous Urey-Miller experiment mixed together chemicals that were present early in Earth's history, then approximately replicated the environmental conditions on the planet at that ...
Understanding natural compounds
Antibiotic-resistant germs, dangerous viruses, cancer: unsolved medical problems require new and better drugs. Nature can provide the inspiration for new active agents. A computer-based method developed by ...
