Hair dyeing poised for first major transformation in 150 years

Technological progress may be fast-paced in many fields, but one mundane area has been almost left in the doldrums for the last 150 years: The basic technology for permanently coloring hair. That's the conclusion of an analysis of almost 500 article...

Does fluoride really fight cavities by ‘the skin of the teeth’?

In a study that the authors describe as lending credence to the idiom, "by the skin of your teeth," scientists are reporting that the protective shield fluoride forms on teeth is up to 100 times thinner than previously believed. It raises questions ...

A nano-solution to global water problem: Nanomembranes could filter bacteria

BUFFALO, N.Y. -- New nanomaterials research from the University at Buffalo could lead to new solutions for an age-old public health problem: how to separate bacteria from drinking water. To the naked eye, both water molecules and germs are invisi...

Getting more anti-cancer medicine into the blood

Scientists are reporting successful application of the technology used in home devices to clean jewelry, dentures, and other items to make anticancer drugs like tamoxifen and paclitaxel dissolve more easily in body fluids, so they can better fight t...

Small particles show big promise in beating unpleasant odors

Scientists are reporting development of a new approach for dealing with offensive household and other odors -- one that doesn't simply mask odors like today's room fresheners, but eliminates them at the source. Their research found that a deodoran...

No longer just a spectator, silicon oxide gets into the electronics...

In the materials science equivalent of a football fan jumping onto the field and scoring a touchdown, scientists are documenting that one fundamental component of computer chips, long regarded as a passive bystander, can actually be made to act like...

Killer paper for next-generation food packaging

Scientists are reporting development and successful lab tests of "killer paper," a material intended for use as a new food packaging material that helps preserve foods by fighting the bacteria that cause spoilage. The paper, described in ACS' journa...

Advance could speed use of genetic material RNA in nanotechnology

Scientists are reporting an advance in overcoming a major barrier to the use of the genetic material RNA in nanotechnology -- the field that involves building machines thousands of times smaller than the width of a human hair and now is dominated ...

New ‘frozen smoke’ material: 1 ounce could carpet three football fields

Scientists are reporting the development of a new, ultra-light form of "frozen smoke" -- renowned as the world's lightest solid material -- with amazing strength and an incredibly large surface area. The new so-called "multiwalled carbon nanotub...
