Hydraulic microelectrode advancermade by David Hubel. David Hubel was a giant in our field, yet he waswarm, friendly, and humble in person. He and Torsten Wiesel, following in the footsteps of their mentor Steve Kuffler, discovered fundamental principles of information processing in the brain and fundamental principles of how the brain wires itself up. I think many people in the field see David...

Being admitted unexpectedly to hospital is depersonalising and distressing. This is compounded for the one inpatient in eight who has delirium. Delirium affects 20-30% of over 65s during acute admission.We should domore to prevent delirium, ensure that we don’t miss it, to reverse it, explain it, and minimise its impact. Clinical staff need support to do this. Risk increases if you’re older and...

David Hillis was born in Copenhagen, Denmark, and grew up in the Belgian Congo, India, and the United States. His undergraduate training was at Baylor University (BS 1980) and graduate work was at the University of Kansas (PhD 1985). He is currently the Roark Centennial Professor at the University of Texas (Austin). He served as the first Director of the School of Biological Sciences at the Uni...

“Interdisciplinary” has become a buzzword in science in recent years. According to David Heeger, a professor of psychology and neural science at New York University (NYU), “You don’t do interdisciplinary science by putting a physicist and a biologist in the same office. Nor do you make interdisciplinary science happen by taking a grant proposal and assigning it for review to people from a diffe...

Human activities are creating major environmental changes on the planet, contributing to habitat loss, climate change, pollution, and consumption of natural resources. Such changes place enormous pressures on biodiversity, disrupting long-standing evolutionary processes. David Jablonski, a paleontologist at the University of Chicago and a recently elected member of the National Academy of Scien...

I give a brief review of Big Bang Nucleosynthesis (BBN) and of the Cosmic Microwave Background Radiation (CMBR). The methods used to constrain YP by the CMBR are then discussed, including methods later discarded in favor of others. To conclude, I give limits found by our analysis and discuss the implications of said limits.

and admired but few are loved. Th e avalanche of tributes and accolades that have fl ooded in since the tragic and premature death of David Bennett demonstrates the intense warmth and aff ection in which he was held. David qualifi ed from the Middlesex Hospital, London, in 1963. He spent a year as a Fulbright scholar in the pulmonary physiology lab at Johns Hopkins in Baltimore but otherwise wo...

The article reviews the research of David Gale, who made lasting contributions to game theory, general-equilibrium theory, and growth theory. In addition to his influence on the development of economic theory, his work has had important implications for many branches of mathematics and on mathematical education.
