Micropore labyrinths as crucibles of life
Water-filled micropores in hot rock may have acted as the nurseries in which life on Earth began. An LMU team has now shown that temperature gradients in pore systems promote the cyclical replication and ...
Programmed synthesis towards multi-substituted benzene derivatives
Chemists at the Institute of Transformative Bio-Molecules (ITbM), Nagoya University and the JST-ERATO Project have developed a new method to accomplish the programmed synthesis of benzene derivatives with ...
Freshmen-level chemistry solves the solubility mystery of graphene oxide films
A Northwestern University-led team recently found the answer to a mysterious question that has puzzled the materials science community for years—and it came in the form of some surprisingly basic chemistry.
Stunning zinc fireworks when egg meets sperm
Sparks literally fly when a sperm and an egg hit it off. The fertilized mammalian egg releases from its surface billions of zinc atoms in "zinc sparks," one wave after another, a Northwestern University-led ...
Breakthrough simplifies design of gels for food, cosmetics and biomedicine
(Phys.org) —Scientists at the University of Strathclyde and City University of New York have created methods that dramatically simplify the discovery of biological gels for food, cosmetics and biomedicine, ...
New chemical sponge has potential to lessen the carbon footprint of oil industry
UK scientists have discovered a ground-breaking technique with the potential to dramatically reduce the amount of energy used in the refinement of crude oil.
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 ...
Where did all the xenon go?
(Phys.org) —The noble gas xenon should be found in terrestrial and Martian atmospheres, but researchers have had a hard time finding it.
'Sticky' ends start synthetic collagen growth
Rice University researchers have delivered a scientific one-two punch with a pair of papers that detail how synthetic collagen fibers self-assemble via their sticky ends.
Crystallizing the DNA nanotechnology dream: Scientists have designed the first large DNA crystals
DNA has garnered attention for its potential as a programmable material platform that could spawn entire new and revolutionary nanodevices in computer science, microscopy, biology, and more. Researchers have been working ...
