Study shows isolation of stem cells may lead to a treatment for hearing loss
...r a whisper. These hair cells differ in length by minuscule amounts and are set in motion by specific frequencies of sound. We hear this sound because this motion induces the hair cell to release an electrical impulse which passes along the auditory nerve to the brain. If the sound is too loud, the hair cel...Protein structures for the entire yeast proteome

...studied populations of the lizard Anolis sagrei on minuscule islands, or cays, in the Bahamas. They introduced to six of these cays a larger, predatory lizard (Leiocephalus carinatus) commonly found on nearby islands and known as a natural colonizer of small cays. The scientists kept six other control cays pre...ACS news service Weekly PressPac -- August 16, 2006
...scribes how some nanoscience researchers liken the minuscule particles they are making -- and mixing and matching like atoms -- to the elements of a new periodic table. Of course, the traditional periodic table is far more than a listing of all the known chemical elements and their properties. It is a powerf...'Micro-boxes' of water used to study single molecules
...ST) have demonstrated the use of water droplets as minuscule "boxes" for small numbers of biomolecules. The unusually simple containment method may enable easier experiments on single molecule dynamics and perhaps lead to the development of molecule-sorting devices that might be used for medical screening or b...Study shows our ancestors survived 'Snowball Earth'
... process. The crystal fragments contained numerous minuscule pockets of fluid mostly consisting of water but also containing small amounts of oil, usually in a thin film around a bubble of water vapor. The oil resulted from decaying organic matter, probably of marine origin. "A drop of oil is a treasure trove....Carnegie scientists fine-tuning methods for Stardust analysis
...itted; the NanoSIMS is an ideal tool for analyzing minuscule Stardust grains because it has greater sensitivity than previous ion probes. The team also plans to study the physical and chemical details of Stardust grains using two different spectroscopic techniques.

...'s smallest biological entities - the viruses. Too minuscule to be usefully observed with many conventional imaging devices, viruses' internal structures must often be viewed with microscopes that require sophisticated computer control to make sense of the tiny objects.

...ue Chen has clarified the connection between these minuscule gates - which are called membrane transport proteins - and the steps by which they use a cell's energy to permit or deny materials entry into the interior of the cell from the outside world. In what the team perceives to be a three-step process, cell...Nanowires can detect molecular signs of cancer, scientists find
... to this exceptional accuracy and sensitivity, the minuscule devices also promise to pinpoint the exact type of cancer present with a speed not currently available to clinicians. A paper describing the work will appear in October in the journal Nature Biotechnology and is now posted on the journal's web site. ...New chemistry method uses 'test tubes' far smaller than the width of a hair
...new substances. This nanoscale "laboratory" is so minuscule that it covers just 1 percent of the width of a human hair, said Daniel Chiu, a UW associate chemistry professor who is developing the unique method.
