The seemingly simple task of maintaining a constant volume isn’t so simple for a cell. The cell membrane is readily crossed by water, which can flow outward or inward so long as it evens out the concentrations of dissolved ions and molecules on either side of the membrane. Water has no interest in whether a cell shrivels like a raisin or expands until it bursts like an overinflated balloon. Since water tends to follow solutes, the cell can manage its water content, and hence its volume, by managing its solutes. In fact, the cell is known to have an ion channel, called VRAC (for volume-regulated anion channel), that acts like a safety valve. VRAC opens in response to cell swelling and permits an outflow of anions, negatively charged ions such as chloride ions, which has the effect of leading water out of the cell. Although VRAC has been known to exist for decades, it has kept its molecular identity a secret, much to the chagrin of scientists. While they tried to discover the genes and proteins that account for VRAC, scientists failed, and so they had no way of knowing whether mutated genes and/or faulty proteins could lead to a poorly functioning VRAC—a sticky valve—to say nothing of causing disease. Scientists, however, have just announced that they have identified an essential component of VRAC. In the April 10 issue of Cell, a research team led by scientists at The Scripps Research Institute (TSRI) described how it used a cell-based fluorescence assay and performed a gen...

As there is such a wide range of safety valves, there is no difficulty in selecting a safety valve that meets the specific requirements of a given application. Once a suitable type has been selected, it is imperative that the correct relieving pressure and discharge capacity are established, and a suitably sized valve and set pressure is specified. The selection of a specific type of safety valve is governed by several factors: • Cost - This is the most obvious consideration when selecting a safety valve for a non-critical application. When making cost comparisons, it is imperative to consider the capacity of the valve as well as the nominal size. As mentioned in the previous module, there can be large variations between models with the same inlet connection but with varying lift characteristics. • Type of disposal system - Valves with an open bonnet can be used on steam, air or non-toxic gas, if discharge to the atmosphere, other than through the discharge system, is acceptable. A lifting lever is often specified in these applications. For gas or liquid applications, where escape to the atmosphere is not permitted, a closed bonnet must be specified. In such applications, it is also necessary to use either a closed/gas tight cap or packed lever. For applications with a significant superimposed backpressure (common in manifolds, typically seen in the process industry) a balancing bellows or piston construction is required. • Valve construction - A semi-nozzle type construct...

A calcium-leak channel prevents calcium overload in cellular organelles for protection of life. Viewing from within the membrane, the structure is shown as ribbons for the closed-conformation. The di-aspartyl pH-sensor unit and the arginine/aspartate lock are shown as sticks covered by electron densities in magenta. (Phys.org) —Sometimes a cell has to die—when it's done with its job or inflicted with injury that could otherwise harm an organism. Conversely, cells that refuse to die when expected can lead to cancer. So scientists interested in fighting cancer have been keenly interested in learning the details of "programmed cell death." They want to understand what happens when this process goes awry and identify new targets for anticancer drugs. The details of one such target have just been identified by a group of scientists from the U.S. Department of Energy's Brookhaven National Laboratory, Columbia University, New York University, Baylor College of Medicine, Technical University of Munich, and the New York Structural Biology Center.

There has been a boom in ebike builders making their own battery packs out of the popular 18650-format cells (18mm diameter, 65mm long), and I want to share what I’ve found out about the guts of an 18650, so you will understand more about proper DIY pack-building methods. Why would somebody make their own pack? The existing battery pack vendors will only make (and stock) the packs that they think they will sell enough of, to make it worth risking their available cash. Which means, they will only have packs with certain particular sizes, shapes, and with specific cost-effective cells. Nobody makes a pack this exact shape and size, and frame shapes vary widely from one model to the next. If this builder settled on buying a turn-key pack, it would have fewer volts, fewer amps, or both. Pic courtesy of firefighter Barry Morfill, in Shrewsbury, UK. But…what if you want a pack with a different cell? Or maybe, you desire a very custom shape? There’s nothing “wrong” with a turn-key battery pack, but…we are under the impression that anyone who is going to go to the trouble and expense of building their own pack, they are likely to also be the type of person who wants high-performance. After all, why go to the expense and trouble of building a low-to-medium performance pack in a conventional shape? They already exist, and they are getting very affordable. (For building a custom pack, the most-often cited DIY cell spot-welder is about $250!) This is a graphic from a custom battery bu...

1 2 Details of calcium 'safety-valve' in cells explained Date: June 6, 2014 Source: DOE/Brookhaven National Laboratory Summary: The atomic level structure of a protein that regulates the level of calcium in cells has been detailed by scientists, providing clues about a key signaling agent that can trigger programmed cell death and potentially leading to new anticancer drug targets.
