Leland Stanford Junior University, or more commonly Stanford University, is a private research university in Stanford, California, and one of the world's most prestigious institutions, with the highest undergraduate selectivity and the top position in numerous surveys and measures in the United States.Stanford was founded in 1885 by Leland Stanford, former governor of and U.S. senator from California and leading railroad tycoon, and his wife, Jane Lathrop Stanford, in memory of their only child, Leland Stanford, Jr., who had died of typhoid fever at age 15 the previous year. Stanford was opened on October 1, 1891 as a coeducational and non-denominational institution. Tuition was free until 1920. The university struggled financially after Leland Stanford's 1893 death and after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, Provost Frederick Terman supported faculty and graduates' entrepreneurialism to build self-sufficient local industry in what would later be known as Silicon Valley. By 1970, Stanford was home to a linear accelerator, and was one of the original four ARPANET nodes .Stanford is located in northern Silicon Valley near Palo Alto, California. The University's academic departments are organized into seven schools, with several other holdings, such as laboratories and nature reserves, located outside the main campus. Its 8,180-acre campus is one of the largest in the United States. The University is also one of the top fundraising institutions in the country, becoming the first school to raise more than a billion dollars in a year.Stanford's undergraduate program is the most selective in the country with an acceptance rate of 5.07% for the 2018 Class. Students compete in 36 varsity sports, and the University is one of two private institutions in the Division I FBS Pacific-12 Conference. It has gained 105 NCAA team championships, the second-most for a university, 465 individual championships, the most in Division I, and has won the NACDA Directors' Cup, recognizing the university with the best overall athletic team achievement, every year since 1994-1995.Stanford faculty and alumni have founded many companies including Google, Hewlett-Packard, Nike, Sun Microsystems, and Yahoo!, and companies founded by Stanford alumni generate more than $2.7 trillion in annual revenue, equivalent to the 10th-largest economy in the world. Fifty-nine Nobel laureates have been affiliated with the University, and it is the alma mater of 30 living billionaires and 17 astronauts. Stanford has produced a total of 18 Turing Award laureates, the highest in the world for any one institution. It is also one of the leading producers of members of the United States Congress.

Eighty percent of individuals with multiple sclerosis (MS) initially develop a clinical pattern with periodic relapses followed by remissions, called relapsing-remitting MS (RRMS). This period of fluctuating disease may last for a decade or more. Clinical relapses reflect acute inflammation in the central nervous system (CNS), composed of the brain and spinal cord. Often, different anatomic areas in the CNS are involved each time a relapse occurs, resulting in varied clinical manifestations in each instance. Relapses are nearly always followed by some degree of remission, though recovery to baseline status before the flare is often incomplete. There are nine approved drugs for treatment of RRMS. The most potent drug for inhibiting relapses, the humanized anti-α4 integrin antibody known as Natalizumab, blocks homing of mononuclear cells to the CNS. The mechanisms of action of the approved drugs for RRMS provide a strong foundation for understanding the pathobiology of the relapse. Despite substantial progress in controlling relapses with the current armamentarium of medications, there is much to learn and ever more effective and safe therapies to develop. © 2014 by Annual Reviews.

A fundamental question in cell biology is how cells determine membrane compartment identity and the directionality with which cargoes pass through the secretory and endocytic pathways. The discovery of so-called 'Rab cascades' provides a satisfying molecular mechanism that helps to resolve this paradox. One Rab GTPase has the ability to template the localization of the subsequent acting Rab GTPase along a given transport pathway. Thus, in addition to determining compartment identity and functionality, Rab GTPases are likely able to order the events of membrane trafficking. This review will highlight recent advances in our understanding of Rabs and Rab cascades. © 2013 Elsevier Ltd.

Water is a critical component of many chemical processes, in fields as diverse as biology and geology. Water in chemical, biological, and other systems frequently occurs in very crowded situations: the confined water must interact with a variety of interfaces and molecular groups, often on a characteristic length scale of nanometers. Water's behavior in diverse environments is an important contributor to the functioning of chemical systems. In biology, water is found in cells, where it hydrates membranes and large biomolecules. In geology, interfacial water molecules can control ion adsorption and mineral dissolution. Embedded water molecules can change the structure of zeolites. In chemistry, water is an important polar solvent that is often in contact with interfaces, for example, in ion-exchange resin systems.Water is a very small molecule; its unusual properties for its size are attributable to the formation of extended hydrogen bond networks. A water molecule is similar in mass and volume to methane, but methane is a gas at room temperature, with melting and boiling points of 91 and 112 K, respectively. This is in contrast to water, with melting and boiling points of 273 and 373 K, respectively. The difference is that water forms up to four hydrogen bonds with approximately tetrahedral geometry. Water's hydrogen bond network is not static. Hydrogen bonds are constantly forming and breaking. In bulk water, the time scale for hydrogen bond randomization through concerted formation and dissociation of hydrogen bonds is approximately 2 ps. Water's rapid hydrogen bond rearrangement makes possible many of the processes that occur in water, such as protein folding and ion solvation. However, many processes involving water do not take place in pure bulk water, and water's hydrogen bond structural dynamics can be substantially influenced by the presence of, for example, interfaces, ions, and large molecules. In this Account, spectroscopic studies that have been used to explore the details of these influences are discussed.Because rearrangements of water molecules occur so quickly, ultrafast infrared experiments that probe water's hydroxyl stretching mode are useful in providing direct information about water dynamics on the appropriate time scales. Infrared polarization-selective pump-probe experiments and two-dimensional infrared (2D IR) vibrational echo experiments have been used to study the hydrogen bond dynamics of water. Water orientational relaxation, which requires hydrogen bond rearrangements, has been studied at spherical interfaces of ionic reverse micelles and compared with planar interfaces of lamellar structures composed of the same surfactants. Water orientational relaxation slows considerably at interfaces. It is found that the geometry of the interface is less important than the presence of the interface. The influence of ions is shown to slow hydrogen bond rearrangements. However, comparing an ionic interface to a neutral interface demonstrates that the chemical nature of the interface is less important than the presence of the interface. Finally, it is found that the dynamics of water at an organic interface is very similar to water molecules interacting with a large polyether. © 2011 American Chemical Society.

Conversion of carbonaceous solid fuels in carbon fuel cells (CFC) especially those that operated at moderately elevated temperatures is of great interest as concerns about the need for efficient and sustainable energy technologies and clean environment grow in importance on the global agenda. The quest for carbon conversion in fuel cells is not new and has been pursued intermittently for nearly 150 years. Recent interest and research activity in this area is fueled in part by concerns over energy and environment but, more importantly, by the realization that CFCs potentially offer two critically important advantages, namely, significantly higher conversion efficiencies and concentrated CO2 product streams. High efficiencies and low emissions are imperative for sustainability. Fuel cells are electrochemical devices that convert the chemical energy stored in the bonds of fuels into electrical energy. Electrochemical conversion offers inherently higher efficiency than is possible by chemical conversion into electrical energy.

Empathy features a tension between automaticity and context dependency. On the one hand, people often take on each other's internal states reflexively and outside of awareness. On the other hand, empathy shifts with characteristics of empathizers and situations. These 2 characteristics of empathy can be reconciled by acknowledging the key role of motivation in driving people to avoid or approach engagement with others' emotions. In particular, at least 3 phenomena-suffering, material costs, and interference with competition-motivate people to avoid empathy, and at least 3 phenomena-positive affect, affiliation, and social desirability-motivate them to approach empathy. Would-be empathizers carry out these motives through regulatory strategies including situation selection, attentional modulation, and appraisal, which alter the course of empathic episodes. Interdisciplinary evidence highlights the motivated nature of empathy, and a motivated model holds wide-ranging implications for basic theory, models of psychiatric illness, and intervention efforts to maximize empathy.
