Ten years dsU, the bones currently in your body did not actually exist. Like skin, bone constantly renewing itself, shedding old tissue and growing it anew from stem cells in the bone marrow. Now, a new technique developed at Caltech can render intact bones transparent, allowing researchers to observe these stem cells within their environment. The method is a breakthrough for testing new drugs to combat diseases like osteoporosis. The research was done in the laboratory of Viviana Gradinaru (BS 05), assistant professor of biology and biological engineering and a Heritage Medical Research Institute Investigator. It appears in a paper in the April 26 issue of Science Translational Medicine. In healthy bone, a delicate balance exists between the cells that build bone mass and the cells that break down old bone in a continual remodeling cycle. This process is partially controlled by stem cells in bone marrow, called osteoprogenitors, that develop into osteoblasts or osteocytes, which regulate and maintain the skeleton. To better understand diseases high risk of fractures, it is crucial In the work described in the new to test a new drug developed for the Tianqiao and Chrissy Chen study the behavior of stem paper, the team began with bones treating osteoporosis, which affects Institute for Neuroscience cells in bone marrow.

Physicists at the Institute for Quantum Information and Matter at Caltech have discovered the first three-dimensional quantum liquid crystal-a new state of matter that may have applications in ultrafast quantum computers of the future. "We have detected the existence of a fundamentally new state of matter that can be regarded as a quantum analog of a liquid crystal," says Caltech assistant professor of physics David Hsieh, principal investigator on a new study describing the findings in the April 21 issue of Science. "There are numerous classes of such quantum liquid crystals that can, in principle, exist; therefore, our finding is likely the tip of an iceberg." Liquid crystals fall somewhere in between a liquid and a solid: they are made up of molecules that flow around freely as if they were a liquid but are all oriented in the same direction, as in a solid. Liquid crystals can be found in nature, such as in biological cell membranes. Alternatively, they can be made artificially-such as those found in the liquid crystal displays commonly used watches, smartphones, televisions, and other items that have display screens. In a "quantum" liquid crystal, electrons behave like the molecules in classical liquid crystals. That is, the electrons move around freely yet have a preferred direction of flow. The first-ever quantum liquid crystal was discovered in 1999 by Caltech's Jim Eisenstein, the Frank J. Roshek Professor of Physics and Applied Physics. Eisenstein's quantum liquid crystal was two-dimensional, meaning that it was confined to a single plane inside the host material-an artificially grown gallium-arsenide-based metal. Such 2-D quantum liquid crystals have since been found in several more materials including high-temperature superconductors. These are materials that conduct electricity with zero resistance at around -150 degrees Celsius, which is warmer than operating temperatures for traditional superconductors. John Harter, a postdoctoral scholar in the Hsieh lab and lead author of the new study, explains how 2-D quantum liquid crystals behave in strange ways. "Electrons living in this flatland collectively decide to flow preferentially along the x-axis rather than the y-axis even though there's nothing to distinguish one direction from the other," he says. Now Harter, Hsieh, and their colleagues at Oak Ridge National Laboratory and the University of Tennessee have discovered the first 3-D quantum liquid crystal. Compared to a 2-D quantum liquid crystal, the 3-D version is even more bizarre. Here, the electrons not only make a distinction between the x-, y-, and z-axes, but they also have different magnetic properties depending on whether they flow forward or backward on a given axis Continued on page 3 These images show light patterns generated by a rhenium-based crystal using a laser method called optical second- zarmonic voranonal anisoronu.

"Running an electrical current through these materials transforms them from nonmagnets into magnets, which is highly unusual," says Hsieh. "What's more, in every direction that you can flow current, the magnetic strength and magnetic orientation changes. Physicists say that the electrons 'break the symmetry' of the lattice." Harter hit upon the discovery serendipitously. He was originally interested in studying the atomic structure of a metal compound based on the element rhenium In particular, he was trying to characterize the structure of the crystal's atomic lattice using a technique called optical second-harmonic rotational anisotropy. In these experiments, laser light is fired at a material, and light with twice the frequency is reflected back out. The pattern of emitted light contains information about the symmetry of the crystal. The patterns measured from the rhenium-based metal were very strange-and could not be explained by the known atomic structure of the compound "At first, we didn't know what was going on," Harter says. The researchers then learned about the concept of 3-D quantum liquid crystals, developed by Liang Fu, a physics professor at MIT. "It explained the patterns perfectly. Everything suddenly made sense," Harter says. The researchers say that 3-D quantum liquid crystals could play a role in a field called spintronics, in which the direction that electrons spin may be exploited to create more efficient computer chips. The discovery could also help with some of the challenges of building a quantum computer, which seeks to take advantage of the quantum nature of particles to make even faster calculations, such as those needed to decrypt codes. One of the difficulties in building such a computer is that quantum properties are extremely fragile and can easily be destroyed through interactions with their surrounding environment. technique called topological quantum computing-developed by Caltech's Alexei Kitaev, the Ronald and Maxine Linde Professor of Theoretical Physics and Mathematics-can solve this problem with the help of a special kind of superconductor dubbed topological superconductor. "In the same way that 2-D quantum liquid crystals have been proposed to be a precursor to high-temperature superconductors, 3-D quantum liquid crystals could be the precursors to the topological superconductors we've been looking for," says Hsieh "Rather than rely on serendipity tofindtopologicalsuperconductors we may now have a route to rationally creating them using 3-D quantum liquid crystals" says Harter.

The most effective step students can take is to simply ask their professors to post midterm grades or a grade distribution. enrolled in. The survey also sought to find if students are getting their graded work returned. Students reported getting all of their work through week 6 returned in 75% of their classes. In many classes, the problem isn't that students don't get their graded work back. Instead, students often have a poor understanding of how they are doing compared to their peers. well understood expectation that faculty should post midterm grade deficiencies for students who are on track to receive a C- or lower. However, faculty members are not actively instructed or encouraged to post midterm grades for all students. Professor Joe Shepherd noted that many faculty have the impression that only deficiencies need to be posted. feedback measures other than a letter grade can be just as helpful Some professors post a histogram with the distribution of class performance, while other classes publish the mean, first quartile, and third quartile scores. A recent study done by the Academics and Research Committee (ARC) found that the average student sees midterm progress grades in only 45% of the courses they are taking. Midterm progress grades are useful tools that give students feedback on how theyre doing in a class. They are also critical for students who are considering dropping a course. Given how useful midterm grades can be, students are often puzzled and frustrated by how inconsistently they are posted. Based on discussions with teaching faculty across several divisions, the ARC found that many professors During Week 9 of fall term, the ARC sent a survey to the undergraduate population gather information on midterm progress grades. A summary of the survey results can be viewed at arc.caltech.edu under the "Survey Data" link. The ARC asked students how many academic classes on grades they were taking, and of these how many classes posted midterm progress grades, either through REGIS or some other electronic service. Freshmen on pass fail were excluded from the survey. Out of 262 responses, the ARC found that students on average see midterm progress grades in 45% of the courses they are Midterm progress grades are useful tools for students.

He turned in a similar performance PASADENA (Apr. 28, 2017) - Caltech baseball needed a standout performance from starting pitcher Jonah Krop and that's exactlywhat they got when the Beavers hosted Saint Katherines College in the first of a three-game weekend series on Friday afternoon. Behind the strong-armed Krop, the Beavers defeated the Firebirds, 3-1, for their eighth victory of the season. Krop fired five scoreless innings to start the game and manuevered around the adversity he faced in the sixth inning and beyond, almost emotionless on the mound. He certainly had his stuff working, as the Firebirds could only muster three hits on the sophomore. Krop also limited the walks, allowing just three free passes over nine innings while striking out five. After taking his lumps as in the Beavers' historic victory over Pomona-Pitzer Colleges back on Mar. 31. Caltech staked its pitcher to an early lead in the second inning when the returning Chris McCarren knocked in junior Garrett Levine on a shot through the right side. Not to be outdone by Krop's big game, McCarren took responsibility for all three of the Beavers' runs and put his team ahead in the eighth inning. With the bases loaded. McCarren floated a single over the head of the Firebirds' shortstop to score senior Kai Kirk and sophomore Mark Burleson, both of whom provided Caltech with a spark at the top of the order.

While the Beavers could not quite recreate the success from Friday's opening game in the series, one Beaver is now in sole possession of a key single-season record. Sophomore Mark Burleson wrapped 2017 as Caltech's record holder for hits in a single season, breaking the joint record formerly held by Brian Panserini '12 and Greg Fricke 'oo with 46 hits over 38 games. Not to be outdone, fellow sophomore Connor Moffatt had a career year in his own right. Moffatt's 40 hits tied the previous record held by Panserini and Fricke and his 10 doubles tied a single-season record occupied by four former Beavers and one of his teammates- -Burleson, who doubled 10 times in his freshman season.
