Golden nanocrown Chinese researchers have recently made a “golden crown” with a diameter of only a few nanometers. It is a large ring-shaped molecule containing 36 gold atoms. The lords of the ring, a team of researchers from the Universities of Beijing, Hong Kong, and Nanjing report their unusual compound in the journal Angewandte Chemie

New Molecules Could Change the Face of Explosives Detection Chemists have developed complex molecules for use in portable sensors that quickly and reliably detect the presence of plastic explosives, a pressing need for soldiers in Iraq. The molecules can also identify which type of explosive is present, allowing security personnel to quickly determine which material they are dealing with.

Planets by the Dozen You know the planets of our solar system, each a unique world with its own distinctive appearance, size, and chemistry. Mars, with its bitter-cold, rusty red sands; Venus, a fiery world shrouded in thick clouds of sulfuric acid; sideways Uranus and its strange vertical rings. The variety is breathtaking.

How anti-aging products delay ripening of fruit and wilting of flowers When plants encounter ethylene, a gas they also produce naturally as a hormone, the result is softening and ripening in the case of fruit, and wilting and fading in the case of flowers – all of which ethylene promotes.

Boost for 'green plastics' from plants Australian researchers are a step closer to turning plants into ‘biofactories’ capable of producing oils which can be used to replace petrochemicals used to manufacture a range of products.
Chinese ants show promise for fighting arthritis, other diseases Ants may be an unwelcome intruder at picnics, but they could soon be a welcome guest in your medicine cabinet. Chemists in China report identification of substances in a certain species of ants that show promise for fighting arthritis, hepatitis, and other diseases.
'Nanodrop' test tubes created with a flip of a switch Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new device that creates nanodroplet “test tubes” for studying individual proteins under conditions that mimic the crowded confines of a living cell.
Argonne scientists develop techniques for creating molecular movies They may never win an Oscar, but scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now.
Queen's develops safe 'green' decontamination method Research by two Queen’s scientists has resulted in an exciting new method for rapidly and safely destroying toxic agents such as chemical weapons and pesticides.
Crime scene investigations: Gunshot residue analysis on a single gunpowder particle Scientists in Texas are reporting development of an highly dependable, rapid, and inexpensive new method for identifying the presence of gunshot residue (GSR). The test fills a GSR-detection gap that results from wider use of “green” — lead free — ammunition.
As nanotech goes mainstream, 'toxic socks' raise concerns Valued for it’s antibacterial and odor-fighting properties, nanoparticle silver is becoming the star attraction in a range of products from socks to bandages to washing machines. But as silver’s benefits propel it to the forefront of consumer nanomaterials, scientists are recommending a closer examination of the unforeseen environmental and health consequences of nanosilver.
Nuclear scientists eye future landfall on a second 'island of stability' Modern-day scientific Magellans and Columbus’s, exploring the uncharted seas at the fringes of the Periodic Table of the Elements, have landed on one long-sought island — the fabled Island of Stability, home of a new genre of superheavy chemical elements sought for more than three decades.
'Healing clays' show promise for fighting deadly MRSA superbug infections, other diseases Mud may be coming to a medicine cabinet or pharmacy near you. Scientists in Arizona report that minerals from clay could form the basis of a new generation of inexpensive, highly-effective antimicrobials for fighting MRSA infections that are moving out of health care settings and into the community.
NASA launches airborne study of arctic atmosphere, air pollution This month, NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic.
New technique identifies molecular 'biomarkers' for disease University of Florida chemists are the first to use a new tool to identify the molecular signatures of serious diseases -- without any previous knowledge of what these microscopic signatures or “biomarkers” should look like.

Femtogram-level chemical measurements now possible Finding a simple and convenient technique that combines nanoscale structural measurements and chemical identification has been an elusive goal. With current analytical instruments, spatial resolution is too low, signal-to-noise ratio too poor, sample preparation too complex or sample size too large to be of good service.
