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

Voting Machines: Make Your Vote Count!
Human-factors engineers,
along with the National
Institute of Standards and
Technology (NIST) have
developed a rigorous,
standardized test for all
electronic voting machines

Molding Fingerprints
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

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 -
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 -
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 -
Biochemists Develop Diagnostic Tool to ID Strains Faster
Biochemists have developed a new tool that can identify a strain of influenza in hours, instead of the usual days or weeks, potentially speeding up the development of new vaccines. A sample of the ... > more -
Pharmacists Use Spectroscopy to Avoid Administering Wrong Medication
A new optical device helps reduce medication errors by recognizing medications in 30 seconds, through their unique fluorescence fingerprints. Administering the right drugs can save lives, especially ... > more -
Polymer Sponge Catches Household Pollutants in Storm Drains
Storm drains fitted with a spongy material -- a synthetic polymer similar to those used in diapers -- can catch household pollutants such as paint and motor oil as they are washed off by the rain. ... > more -
Portable Machines Go Beyond Prenatal Uses
Ultrasound uses sound waves that bounce off body parts, producing echoes. A computer translates the echoes into images that rival the quality of CAT scans and MRIs, showing broken bones, muscle ... > more
