Darwin's famous finches and Venter's marine microbes
...rove for a diverse group of scientists, who try to squeeze as much information as possible from the largest metagenomic dataset ever collected. For more information about the expedition, please go to: the J. Craig Venter Institute (URL: www.sorcerer2expedition.org and www.venterinstitute.org ) ...Contrary to common wisdom, scientist discovers some mammals can smell objects under water
...the grid were too small for the star appendages to squeeze through but large enough so the air bubbles could pass without difficulty. These trials demonstrated that the moles could follow the scent trail by sniffing alone (without the tactile star). Five moles were tested on earthworm scent trails and f...MIT engineers probe spiders' polymer art
...lippery enough to slide past each other easily and squeeze through the spider's ampullate gland. As the silk gel flows from the gland through an S-shaped, tapered canal to the outside of the spider's body, the long protein molecules become aligned and the viscosity (or resistance to flow) drops by a factor o...3-D model reveals secrets of metastasis

...gital record, the cow is held in what's known as a squeeze chute and the scanner's eye-cup, specially molded for a cow's face, is held to each animal's eye. The scanner senses when the eye is open, automatically makes an image, and downloads the data to a computer database. In addition to the retinal image,...Cells direct membrane traffic by channel width
...rence in diameter is a road-closed sign: You can't squeeze through unless you are a sleek, water-molecule-sized sports car, say scientists at the University of Illinois at Urbana-Champaign.

...e makes it impossible for researchers to get it to squeeze inside viral vectors ?disarmed viruses that are used to shuttle genes into cells. But the team found a good stand-in in a similar protein called agrin that when miniaturized could be inserted inside an adeno-associated virus (AAV) vector. Dr. Xiao's ...Gladstone investigators discover how resting T cells avoid HIV infection
...tor. Initially, scientists thought that A3G had to squeeze into new HIV viral particles in order to produce its antiviral effects. The new Nature study indicates that this is not the case in resting T-cells. The Greene lab showed that in activated T cells, however, Vif, one of HIV's nine genes, counters the ......system as simple as possible. Instead of trying to squeeze everythingonto a single chip, Pria designers started with a desktop diagnosticsystem and shrank it down into a device about the size of a coffee cup.One of the cost-saving aspects of the design was to keep thefluid-handling components separate from t...
