    Description: Bcl-2 family members bearing only the BH3 domain are essential inducers of apoptosis. We identified a BH3-only protein, Bmf, and show that its BH3 domain is required both for binding to prosurvival Bcl-2 proteins and for triggering apoptosis. In healthy cells, Bmf is sequestered to myosin V motors by association with dynein light chain 2. Certain damage signals, such as loss of cell attachment (anoikis), unleash Bmf, allowing it to translocate and bind prosurvival Bcl-2 proteins. Thus, at least two mammalian BH3-only proteins, Bmf and Bim, function to sense intracellular damage by their localization to distinct cytoskeletal structures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Puthalakath, H -- Villunger, A -- O'Reilly, L A -- Beaumont, J G -- Coultas, L -- Cheney, R E -- Huang, D C -- Strasser, A -- CA 80188/CA/NCI NIH HHS/ -- R29 DC003299/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2001 Sep 7;293(5536):1829-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Walter and Eliza Hall Institute of Medical Research, Melbourne, P.O.

    Description: Mesostructured silica waveguide arrays were fabricated with a combination of acidic sol-gel block copolymer templating chemistry and soft lithography. Waveguiding was enabled by the use of a low-refractive index (1.15) mesoporous silica thin film support. When the mesostructure was doped with the laser dye rhodamine 6G, amplified spontaneous emission was observed with a low pumping threshold of 10 kilowatts per square centimeter, attributed to the mesostructure's ability to prevent aggregation of the dye molecules even at relatively high loadings within the organized high-surface area mesochannels of the waveguides. These highly processible, self-assembling mesostructured host media and claddings may have potential for the fabrication of integrated optical circuits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang -- Wirnsberger -- Huang -- Cordero -- McGehee -- Scott -- Deng -- Whitesides -- Chmelka -- Buratto -- Stucky -- New York, N.Y. -- Science. 2000 Jan 21;287(5452):465-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Department of Chemical Engineering, Department of Materials, University of California, Santa Barbara, CA 93106, USA.

    Description: Reelin is an extracellular protein that is crucial for layer formation in the embryonic brain. Here, we demonstrate that Reelin functions postnatally to regulate the development of the neuromuscular junction. Reelin is required for motor end-plate maturation and proper nerve-muscle connectivity, and it directly promotes synapse elimination. Unlike layer formation, neuromuscular junction development requires a function of Reelin that is not mediated by Disabled1 or very-low-density lipoprotein receptors and apolipoprotein E receptor 2 receptors but by a distinct mechanism involving its protease activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Quattrocchi, Carlo C -- Huang, Cheng -- Niu, Sanyong -- Sheldon, Michael -- Benhayon, David -- Cartwright, Joiner Jr -- Mosier, Dennis R -- Keller, Flavio -- D'Arcangelo, Gabriella -- New York, N.Y. -- Science. 2003 Aug 1;301(5633):649-53.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Cain Foundation Laboratories, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12893944" target="_blank"〉PubMed〈/a〉

    Notes: An intense, high-energy electron or positron beam can have focused intensities rivaling those of today's most powerful laser beams. For example, the 5 ps (full-width, half-maximum), 50 GeV beam at the Stanford Linear Accelerator Center (SLAC) at 1 kA and focused to a 3 micron rms spot size gives intensities of 〉1020 W/cm−2 at a repetition rate of 〉10 Hz. Unlike a ps or fs laser pulse which interacts with the surface of a solid target, the particle beam can readily tunnel through tens of cm of steel. However, the same particle beam can be manipulated quite effectively by a plasma that is a million times less dense than air! This is because of the incredibly strong collective fields induced in the plasma by the Coulomb force of the beam. The collective fields in turn react back onto the beam leading to many clearly observable phenomena. The beam paraticles can be: (1) Deflected leading to focusing, defocusing, or even steering of the beam; (2) undulated causing the emission of spontaneous betatron x-ray radiation and; (3) accelerated or decelerated by the plasma fields. Using the 28.5 GeV electron beam from the SLAC linac a series of experiments have been carried out that demonstrate clearly many of the above mentioned effects. The results can be compared with theoretical predictions and with two-dimensional and three-dimensional, one-to-one, particle-in-cell code simulations. These phenomena may have practical applications in future technologies including optical elements in particle beam lines, synchrotron light sources, and ultrahigh gradient accelerators. © 2002 American Institute of Physics.
