    Description: In some ways, the British were playing catch-up. Since the mid-nineteenth century, local universities throughout the German-speaking states had been recruiting academic talent in contests for prestige - latter-day Galileos were snatched up by government-funded institutions. Before long, he was consulting...

    Description: Our brain activity demonstrates amazing stability across multiple time frames ranging from a few milliseconds to several hours. The longer cycles are commonly called ultradian rhythms and they correspond to infralow frequencies (ILFs) in the milli-Hz range (0.001 Hz). Ultradian rhythms between 90 minutes and 2 hours or longer are readily observed in our electroencephalogram, and they reflect periods of activity and rest, cycles of cortical excitability and plasticity followed by relative inactivity. Our nightly sleep is organized into similar stages (rapid eye movement and non–rapid eye movement sleep) as is our daily behavior (ie, the basic rest-activity cycle). Astrocytes often exhibit milli-Hz ILFs, and they play a major role in shaping neuronal plasticity and activity, and thus may organize or influence the basic rhythms of sleep and waking. The nature and importance of astrocytes in human brain functioning is subsequently reviewed.

    Description: Bacteria often practice autoinduction, in which a molecule released and reabsorbed by the same cell adjusts genetic expression according to local density of signalling cells. Autoinducers, first noticed in luminescent bacteria, were identified in Agrobacterium tumefaciens by Margaret More.

    Description: Understanding the behavior of the universe at large depends critically on insights about the smallest units of matter and their fundamental interactions. Inflationary cosmology is a highly successful framework for exploring these interconnections between particle physics and gravitation. Inflation makes several predictions about the present state of the universe-such as its overall shape, large-scale smoothness, and smaller scale structure-which are being tested to unprecedented accuracy by a new generation of astronomical measurements. The agreement between these predictions and the latest observations is extremely promising. Meanwhile, physicists are busy trying to understand inflation's ultimate implications for the nature of matter, energy, and spacetime.

    Description: Byline: Frances K. Del Boca, Thomas F. Babor, Jeremy W. Bray, Jesse Hinde, Jeremy Bray, David Kaiser, Erin Mallonee Keywords: Alcohol; financing; institutions; Medicaid; policy; SBIRT Abstract Aims To examine how institutional constraints, comprising federal actions and states' substance abuse policy environments, influence states' decisions to activate Medicaid reimbursement codes for screening and brief intervention for risky substance use in the United States. Methods A discrete-time duration model was used to estimate the effect of institutional constraints on the likelihood of activating the Medicaid reimbursement codes. Primary constraints included federal Screening, Brief Intervention and Referral to Treatment (SBIRT) grant funding, substance abuse priority, economic climate, political climate and interstate diffusion. Study data came from publicly available secondary data sources. Results Federal SBIRT grant funding did not affect significantly the likelihood of activation (P = 0.628). A $1 increase in per-capita block grant funding was associated with a 10-percentage point reduction in the likelihood of activation (P = 0.003) and a $1 increase in per-capita state substance use disorder expenditures was associated with a 2-percentage point increase in the likelihood of activation (P = 0.004). States with enacted parity laws (P = 0.016) and a Democratic-controlled state government were also more likely to activate the codes. Conclusion In the United States, the determinants of state activation of Medicaid Screening, Brief Intervention and Referral to Treatment (SBIRT) reimbursement codes are complex, and include more than financial considerations. Federal block grant funding is a strong disincentive to activating the SBIRT reimbursement codes, while more direct federal SBIRT grant funding has no detectable effects.

    Description: From the discovery of new galaxies and nearly undetectable dark energy to the quantum entanglement of particles across the universe, new findings in physics naturally elicit a sense of awe and wonder. For the founders of modern physics—from Einstein and Bohr to Heisenberg, Pauli, and Bohm—a fascination with deeper questions of meaning and ultimate reality led some of them to explore esoteric traditions and metaphysics. More recently, however, physicists have largely shunned such philosophical and spiritual associations. What can contemporary physics offer us in the quest to understand our place in the universe? Has physics in some ways become a religion unto itself that rejects the search for existential meaning? Discussion of these and related questions is presented in this paper.
