Controlling chemical mirror images
Chirality, while not a rarity in the world of molecules, is nevertheless a special property. If a molecule is chiral (from the Greek word chiros = hand), it exists in two mirrored versions that are very similar but not identical—like two hands that.....»»

Green eggs and scam: Cuckoo finch"s long con may be up
For two million years African cuckoo finches have been tricking other birds into raising their young by mimicking the colour of their eggs, but new research suggests the tables may be turning in this evolutionary scam......»»
Researchers Create a Magnet Made of One Molecule
Sometimes making a brand-new type of box requires outside-the-box thinking, which is exactly what Spartan chemists used to create an eight-atom, magnetic cube. Phys.Org reports: Part of what made the researchers' idea so wild was their choice to work.....»»
Research could enable assembly line synthesis of prevalent amine-containing drugs
A University of Illinois at Urbana-Champaign research team has discovered a way to produce a special class of molecule that could open the door for new drugs to treat currently untreatable diseases......»»
Study identifies therapeutic target for Alzheimer’s disease, revealing strategy for preventing or slowing disease progression
A new study suggests a key protein molecule plays a major role in the accumulation of brain cholesterol, triggering the development of Alzheimer's and supporting the use of peptide inhibitors as a therapeutic treatment target. The study found that mi.....»»
Discovery provides insight into neglected tropical disease schistosomiasis
A team led by UTSW researchers has identified a molecule produced by male parasitic worms called schistosomes that prompts sexual maturity in females of these species. The findings, reported in Cell, help answer a century-old mystery and could lead t.....»»
People around the world like the same kinds of smells
What smells we like or dislike is primarily determined by the structure of the particular odor molecule. A collaborative study involving researchers from Karolinska Institutet, Sweden, and the University of Oxford, UK, shows that people share odor pr.....»»
Researchers create a sea of nano-sized gold stars
Researchers from the Department of Energy's Pacific Northwest National Laboratory (PNNL) and the University of Washington (UW) have successfully designed a bio-inspired molecule that can direct gold atoms to form perfect nanoscale stars. The work is.....»»
Checkpoints enable precision in cells" molecule intake
Cells are much more precise in how they ingest substances than previously thought, new research finds, opening the door to potential treatments for several diseases......»»
Stimulating the sense of touch with chemistry
Our eyes may be windows on the world, but our fingertips put us in touch with it. To recreate this tactile sense, current technology relies on tiny motors and electricity. However, the bumps and buzzes they generate are not that good at mimicking the.....»»
Cryo-EM reveals how "911" molecule helps fix damaged DNA
When something goes wrong during DNA replication, cells call their own version of 911 to pause the process and fix the problem—a failsafe that is critical to maintaining health and staving off disease......»»
Scientists discover how molecule becomes anticancer weapon
Years of toil in the laboratory have revealed how a marine bacterium makes a potent anti-cancer molecule......»»
New insight into the possible origins of life
Researchers at the University of Tokyo have for the first time been able to create an RNA molecule that replicates, diversifies and develops complexity, following Darwinian evolution. This has provided the first empirical evidence that simple biologi.....»»
New paradigm in atmospheric gas sensing and molecular identification
Graphene, an atomic-thick sheet of carbon has found immense applications in gas sensors due to its single-molecule sensitivity, low-noise levels, and high carrier density. However, graphene's much-heralded sensitivity also means it is inherently non-.....»»
