    Bonding Time

    Sarah Trice and Gary Molander alter the landscape of pharmaceutical synthesis.

    In the grand scheme of things, a tiny molecule can mean a lot—especially in Penn Chemistry’s High Throughput Experimentation Laboratory. The state-of-the-art laboratory is capable of testing hundreds of reactions a day, as opposed to only a handful previously.

    The Buzz on Plant-Pollinator Networks

    Daniel Song investigates pollination patterns in Mongolia.

    Daniel Song, a third-year doctoral student in biology who studies plant-pollinator networks, is quick to note he’s not the first person to examine correlations between plants and the insects who fertilize them. “For as long as people have been collecting honey, they’ve been understanding pollinators,” he says.

    Zeroing in on the Higgs

    Brig Williams and team close in on the mysterious “God particle.”

    One day this past December, physicist Brig Williams was waiting to hear whether he and his colleagues had helped make history.

    Under Pressure

    Arjun Yodh and Andrea Liu tame the disordered solid.

    The lazy melody of a wind chime; the roar of a gong; the chirp of a bell—what do these sounds all have in common? Each is produced by the organized vibrations of atoms in an ordered solid, also known as a crystal. While all solids contain flaws, defects in crystals manifest in easily recognizable patterns.

    Wear and Tear

    Senior Shirley Leung documents the consequences of soil erosion.

    We often attribute water pollution to trash or gasoline, waste that is irresponsibly discarded into natural habitats. Indeed this is a serious issue, but ironically enough, some of the decline in water quality can be pinned on nature itself—but that doesn’t mean humans get a pass.

    Mutual Attraction

    Ivan Dmochowski and David Jacobson peer into radon’s binding preferences.

    It often hides in your basement and is most likely to strike while you’re asleep. This isn’t your ordinary assailant lurking in the dark, however—this is radon: a deadly, odorless, tasteless, colorless gas bred from the decay of radioactive materials. How then do you go about conducting research on such a deadly element?

    Quarky Conversations

    The Cosmic Tenors bring physics to a lecture hall near you.

    You might expect singing when attending an event featuring the Cosmic Tenors. But that would be trite—after all, who has time for singing when you’re discussing the teleportation devices from Star Trek? It’s just one of the many questions the Tenors, a trio of physicists, have fielded during their far-reaching lectures.

    Asleep at the Wheel

    Ted Abel investigates sleep deprivation’s effect on cognition.

    The next time you choose to pull an all-nighter, cramming for a test or preparing for a work presentation, think again—you’re likely damaging the exact neurological systems you hope to utilize for success. The negative effect of a lack of sleep on cognitive abilities like memory may not seem like news. In fact, it is anecdotally taught to us from a very young age.

    Lending an Ear

    John Trueswell and Lila Gleitman use adults to mimic the language-learning process in infants.

    Parents, you might want to go easy on the flashcards.

    A Sounder Sleep

    Video: Joshua Warren exposes the inner workings of sleep apnea.

    We all struggle to get our 8 hours. Whether it’s that last-minute work project, a test you’re cramming for, or a newborn, there are a myriad of roadblocks to a good night’s sleep.
