Why is there no new Einstein? |

I am sure I am not the only one in this year of Einstein who receives calls from journalists asking, "Why is there no new Einstein?" While we have ready answers, there is still the disquieting worry that perhaps a lesson might be learned from the fact that this one person, who was initially unable to find an academic job, did more to advance physics than most of the rest of us put together have since.
Two from the archive: Paul Graham: It will always suck to work for large organizations, and the larger the organization, the more it will suck.
Richard Hamming: I finally adopted what I called "Great Thoughts Time." When I went to lunch Friday noon, I would only discuss great thoughts after that. By great thoughts I mean ones like: "What will be the role of computers in all of AT&T?", "How will computers change science?" For example, I came up with the observation at that time that nine out of ten experiments were done in the lab and one in ten on the computer. I made a remark to the vice presidents one time, that it would be reversed, i.e. nine out of ten experiments would be done on the computer and one in ten in the lab. They knew I was a crazy mathematician and had no sense of reality. I knew they were wrong and they've been proved wrong while I have been proved right. They built laboratories when they didn't need them. I saw that computers were transforming science because I spent a lot of time asking "What will be the impact of computers on science and how can I change it?" I asked myself, "How is it going to change Bell Labs?" I remarked one time, in the same address, that more than one-half of the people at Bell Labs will be interacting closely with computing machines before I leave. Well, you all have terminals now. I thought hard about where was my field going, where were the opportunities, and what were the important things to do. Let me go there so there is a chance I can do important things.

The main purpose of the project Videolectures.Net is to provide free and open access of a high quality video lectures presented by distinguished scholars and scientists at the most important and prominent events like conferences, summer schools, workshops and science promotional events from many fields of Science. The portal is aimed at promoting science, exchanging ideas and fostering knowledge sharing by providing high quality didactic contents not only to a scientific community but also to a general public.

In making the case that she would be a better President than Barack Obama, Hillary Rodham Clinton never forgets to summon the argument that she has more experience. But experience doesn't always help. In fact, three decades of research into expert performance has shown that experience itself — the raw amount of time you spend pursuing any particular activity, from brain surgery to skiing — can actually hinder your ability to deliver reproducibly superior performance.

How we judge the thoughts of others |

How do we know what another person is thinking? New research suggests we use the same brain region that we do when thinking about ourselves — but only as long as we judge the person to be similar to us. When second-guessing the opinions and feelings of those unlike ourselves, this brain region does not get involved, the new research shows. This may mean we are more likely to fall back on stereotyping — potentially helping to explain the causes of social tensions such as racism or religious disputes.

Another example that we've been investigating are huge swarms of Mormon crickets. If you look at these swarms, all of the individuals are marching in the same direction, and it looks like cooperative behavior. Perhaps they have come to a collective decision to move from one place to another. We investigated this collective decision, and what really makes this system work in the case of the Mormon cricket is cannibalism.
From the archive: If Americans were to reduce meat consumption by just 20 percent it would be as if we all switched from a standard sedan -- a Camry, say -- to the ultra-efficient Prius.

You can accuse the disgraced ex-governor Eliot Spitzer of many things in his decision to flout the law by soliciting the services of a pricey prostitute: hypocrisy, egomania, sophomoric impulsiveness and self-indulgence, delusional ineptitude and boneheadedness. But one trait decidedly not on display in Mr. Spitzer’s splashy act of whole-life catabolism was originality.

NIH Scientists Offer Explanation for Winter Flu Season |

A finding by a team of scientists at the National Institutes of Health may account for why the flu virus is more infectious in cold winter temperatures than during the warmer months. At winter temperatures, the virus's outer covering, or envelope, hardens to a rubbery gel that could shield the virus as it passes from person to person, the researchers have found. At warmer temperatures, however, the protective gel melts to a liquid phase. But this liquid phase apparently isn't tough enough to protect the virus against the elements, and so the virus loses its ability to spread from person to person.
The full study is here: Using linewidth and spinning sideband intensities of lipid hydrocarbon chain resonances in proton magic angle spinning NMR spectra, we detected the temperature-dependent phase state of naturally occurring lipids of intact influenza virus without exogenous probes. Increasingly, below 41 °C ordered and disordered lipid domains coexisted for the viral envelope and extracts thereof. At 22 °C much lipid was in a gel phase, the fraction of which reversibly increased with cholesterol depletion. Diffusion measurements and fluorescence microscopy independently confirmed the existence of gel-phase domains. Thus the existence of ordered regions of lipids in biological membranes is now demonstrated. Above the physiological temperatures of influenza infection, the physical properties of viral envelope lipids, regardless of protein content, were indistinguishable from those of the disordered fraction. Viral fusion appears to be uncorrelated to ordered lipid content. Lipid ordering may contribute to viral stability at lower temperatures, which has recently been found to be critical for airborne transmission.

Virtual Organizations as Sociotechnical Systems |

A virtual organization is a group of individuals whose members and resources may be dispersed geographically, but who function as a coherent unit through the use of cyberinfrastructure. Virtual organizations are increasingly central to the science and engineering projects funded by the National Science Foundation. Focused investments in sociotechnical analyses of virtual organizations are necessary to harness their full potential and the promise they offer for discovery and learning. The Virtual Organizations as Sociotechnical Systems (VOSS) program supports scientific research directed at advancing the understanding of what constitutes effective virtual organizations and under what conditions virtual organizations can enable and enhance scientific, engineering, and education production and innovation. Levels of analysis may include (but are not limited to) individuals, groups, organizations, and institutional arrangements. Disciplinary perspectives may include (but are not limited to) anthropology, complexity sciences, computer and information sciences, decision and management sciences, economics, engineering, organization theory, organizational behavior, social and industrial psychology, public administration, and sociology. Research methods may span a broad variety of qualitative and quantitative methods, including (but not limited to): ethnographies, surveys, simulation studies, experiments, comparative case studies, and network analyses. VOSS funded research must be grounded in theory and rooted in empirical methods. It must produce broadly applicable and transferable results that augment knowledge and practice of virtual organizations as a modality. VOSS does not support proposals that aim to implement or evaluate individual virtual organizations.
