Protecting Your Hair
Hair conditioners can help
protect your hair by
replacing natural oils that
are lost while shampooing.
But now, an atomic-force
microscope reveals that some
conditioners do not protect
the hair because they don't

Materials Chemists Apply Photonic Crystals to Forensics
Photonic crystals -- materials with precise patterns of gaps that make them reflect only selected wavelengths of light -- could soon replace the traditional ink-based fingerprinting. In a new ... > more -
Nanotechnology Fingerprints Can Certify Authenticity
Immunochemists have now devised a range of nanoscale materials that can be embedded in drug packaging or in the pills themselves to distinguish medicines from counterfeits. Traces of these ... > more -
Chemists Steal Engineering Tricks from Sponges
Sponges are the homes of colonies of tiny marine animals, and wonders of miniaturized engineering. They employ complex structural arrangements, the strongest glasses known to man, and even ... > more -
Physical Chemists Devise Quick Spectrometry-Based Mercury Test
Physical chemists have created a new, cheap test to detect mercury, an element known to harm the brain, kidneys, heart, lungs and immune system. A gold nanorod absorbs mercury from a sample and, then ... > more -
Industrial Hygienists Suggest Watching Out For Mold When Going Green
Industrial hygienists found that mold, rot, and corrosion are dangers that must be accounted for when builders construct energy-efficient homes. Recycled materials used in this type of construction ... > more -
Materials Scientists Make Valentine Treats Affordable
New and improved technology has now made growing diamonds cost-competitive with mining them. Diamond-making machines subject a graphite-carbon core and a diamond seed at a pressure of 850,000 PSI for ... > more -
An Interactive, 3D Voyage into Human Anatomy
Anatomists and biochemists have created a detailed virtual view of vital organs in the human body, down to the level of tissues and cells. The software recreates the visualization from a combination ... > more -
Viral Immunologists Invent Speedy Virus Identification Technique
Chemists and immunologists devised a new rapid system for detecting and identifying viruses. It uses surface enhanced Raman spectroscopy to measure the frequency of near-infrared laser light as it ... > more -
Biochemists And Engineers Create Fast-acting Pathogen Sensor
Engineers invented a device to bring air samples into contact with genetically engineered biosensors in the effort to detect dangerous biological agents. The technology uses multiple collections of ... > more -
Biomedical Engineers' 'Body-on-a-Chip' Could Reduce Cost of Developing New Drugs
A new kind of microchip can host human cells to mimic the reaction of different tissues in the body. The chip could help reduce the need for animal testing, and lower the cost of developing new ... > more
