According to a Pew Research survey of 3,003 Americans, conducted in recent days (but just before 13 August 2010 when President Obama defended Muslims' right to build an Islamic centre near Ground Zero in New York) a growing number of Americans incorrectly believe that President Barack Obama is a Muslim. Some 18% said the President was a Muslim (up from 11% in March 2009) and among Republican supporters, that number was 34%. Just less than that (a third of those quizzed) correctly identified Mr. Obama as a Christian, despite his regular public observations of his faith. Forty-three percent of those questioned said they did not know what Mr. Obama's religion was…

Professor Zichichi, Distinguished Guests, Ladies and Gentlemen,
It is a great pleasure to be here with you in Erice today to discuss ITU's perspective on Science and the future of Cyberspace. Given that they are now so completely interdependent, however, I could just as easily say that I am here to discuss ITU's perspective on Cyberspace and the Future of Science…

Vast reductions in deployed nuclear weapons have taken place, and the international consensus against nuclear weapon proliferation is strong. However, world security is threatened by emergent nuclear powers and especially by the growing threat of non-state deliberate unauthorized use of state-owned nuclear weapons and by the threat of improvised nuclear explosives fashioned from stocks of weapon-usable fissionable materials—highly-enriched uranium or plutonium

The rapid global warming rate of 0.16 K/decade from 1975-2001, near-identical to those observed from 1860-1880 and 1910-1940 that pre-dated significant anthropogenic influence, may also have been chiefly natural. Based on simplified methods for determining climate sensitivity without resorting to general-circulation models, the natural global brightening of 2.6 W m−2 observed in the 18 years 1983-2001 should have caused a transient global warming of 0.6 K or, after adding anthropogenic warming, 0.8 K: yet <0.35 K warming was observed. Likewise, over the 56 years 1950-2005, assuming no net global brightening or dimming, anthropogenic transient warming of 1.45 K should have occurred: yet only 0.65 K was observed. Accordingly, current estimates may overstate climate sensitivity by a factor >2. Improved analysis of variations in cloud cover will be essential for the eventual determination of climate sensitivity.

The rapid growth in the size and complexity of commercial nuclear power plants in the 1970s spawned an interest in smaller, simpler designs that are inherently or intrinsically safe through the use of passive design features. Several designs were developed, but none were ever built, although some of their passive safety features were incorporated into large commercial plant designs that are being planned or built today. In recent years, several reactor vendors are actively redeveloping small modular reactor (SMR) designs with even greater use of passive features. Several designs incorporate the ultimate in passive safety—they completely eliminate specific accident initiators from the design. Other design features help to reduce the likelihood of an accident or help to mitigate the accident's consequences, should one occur. While some passive safety features are common to most SMR designs, irrespective of the coolant technology, other features are specific to water, gas, or liquid-metal cooled SMR designs. The extensive use of passive safety features in SMRs promise to make these plants highly robust, protecting both the general public and the owner/investor. Once demonstrated, these plants should allow nuclear power to be used confidently for a broader range of customers and applications than will be possible with large plants alone.

Achieving sustainable energy systems for the world is a massive challenge that will require much better energy technologies than are currently commercially available. Inventing these better technologies is underway in many countries. By sustainable is meant technologies that endure, that do no harm, and that leave no permanent negative change in the environment. The evolution toward this desirable state is illustrated, for example, by the efforts in the United States over the past decade to analyze basic research needs for achieving sustainable energy technologies and to pursue them systematically. Needless to say the objective has not been attained although substantial progress is being made. Silver bullets are rare. Much larger research investments, public and private are needed, and they must be sustained for decades. Can the political will be motivated? Sustainable energy will require not only better technology but also better policies to incentivize invention and to encourage deployment.

Physics, chemistry and biology using synchrotron light sources and free electron lasers—now commonly called photon science—can be instrumental in providing the scientific basis for a sustainable energy future. As an example, it considers the use of sunlight to generate electricity and transportable fuels. Even in this limited arena this report makes no attempt to be comprehensive about the many ways in which photon science can be a disruptive agent in the research agenda for sustainable energy. Rather it is a call to action to use the several dozens of accelerator-based science facilities that are available worldwide.

Refocusing on the role of science and applied science as the motor of progress, in an interdisciplinary setting, is nowhere more apposite than in the further expansion and development of the digital world.

Science is the must for human culture of the third millennium. The exceptional role in this process is played by information and communication technologies (ICT), and the high demand for ICT leads to many forms of it: Internet, Mobile Internet, Internet of Things (IoT), Grid Computing, Cloud Computing. The article discusses influences and reflections to our life, caused by recent and future forms of ICT: a centralized and decentralized IoT regime, human privacy protection and protection of personal data, risk of cyber terrorism, communication reflection for the small country (like Lithuania), "silence of chips", some others. IoT is based on the idea of a worldwide, wireless, integrated network of smart facilities and devices ("things") as well as a whole range of different sensors and actuators, in which, using standard protocols, the "things" communicate with each other, and with people. Technically, the road to IoT covers device integration, certification and maintenance, service provisioning, as devices participating in IoT need to talk to each other, not just to people. Such phenomena are presented in the article as a challenge to interdisciplinary research. Future generations will have a smart live in a global environment, if we care more about sustainable development and planetary emergencies.

For many decades, it has been accepted that particles in ambient air can harm human health. However, only within the last decade have advances in air pollution statistics and science made it possible to evaluate which specific types of tiny airborne particles might be most harmful to human health, or perhaps have limited toxicity.
Population-based epidemiology is the standard method by which an air pollutant's harm to populations is estimated. It is important to include a large number of potentially harmful PM2.5 species in a given epidemiology model, so researchers can be assured that any associations found are not due to the absence of potentially important PM2.5 species. However, due in part to a lack of standardized available monitoring information for many different PM2.5 species, epidemiology studies rarely included many PM2.5 species in models until relatively recently. Epidemiology studies from the 1990s rarely included more than one or two PM2.5 species in models of health effect associations (although they often included gases). The only PM2.5 species consistently included in older studies was sulfate, which has been monitored for several decades. Perhaps unsurprisingly, sulfate was frequently associated with the health effects examined in the models.
Because several epidemiology studies with 6 to 20 PM2.5 species have been published since 2008, there is now a "critical mass" of such at least 9 such studies. Cardiovascular disease daily emergency hospital admissions, daily mortality, or survival since enrollment in prospective cohort studies are the health endpoints examined.
In 8 of the 9 studies, black carbon or elemental carbon (BC/EC) is significantly associated with the health endpoint of the study. In 8 of the 9 studies, sulfate is not significantly associated with the health endpoint considered. Despite the fact that the metals vanadium (V) and nickel (Ni) are each a tiny fraction of PM2.5 species, every study which includes Ni, all but one which include V, find health associations with each.
These studies, by themselves, may not be adequate to make policy determinations as to which types of emissions are most harmful, and which emissions may pose little health threats. The consistency of findings, however, is quite surprising. It is doubtful that many air pollution health experts would have predicted such consistent findings. These results may suggest that PM2.5 species capable of causing particular biological effects, such as oxidative stress and inflammation, might be the ones which cause significant portions of chronic and acute mortality and morbidity via these mechanisms. Such a possibility should spur additional toxicology research.
To provide added confirmation of these epidemiological findings, it is important to utilize toxicology and human panel studies, where the exposure to specific emissions is known accurately. Doing so will allow us to see if biological mechanisms of harm found in toxicology, from exposure to particular PM2.5 species, would also be found in studies of humans using the same PM2.5 species. Adverse effects associated with particular PM2.5 species in population-based epidemiology studies, and effects caused by the same species in human panel studies, could then confidently linked. We will briefly review results of some human panel studies which allow such comparison of effects among different types of PM2.5 species. Because effects of BC/EC, and of traffic emissions, have been studied comprehensively, we will also briefly examine findings of two review articles of such studies.

A brief review is given of some of the current ideas concerning global climate since the beginning of the industrial era. While it is generally agreed that there has been a global warming, the cause of this is not universally agreed upon, particularly that it has been caused by greenhouse gases (primarily carbon dioxide) of anthropogenic origin. The arguments implying anthropogenic origin of the warming are discussed, as well as some of the questions raised. What additional work is needed to help clarify the issues is discussed.

The Earth's climate system is dominated by the need for poleward transport of energy. The transport, necessary to bring about near global radiation balance, is achieved largely by the atmospheric circulation (about 80 percent, including the hydrological cycle), although the ocean circulations are also significant contributors. The magnitude of the atmospheric transport is controlled by the rate of exchange of heat and latent energy across the interface between the tropical surface (particularly the ocean) and the atmosphere. The rate of energy exchange from the ocean to the atmosphere is regulated by ocean surface temperature and varies with the rate of mixing of cold interior water into the tropical ocean surface mixed layer.
The impact of varying tropical ocean-atmosphere exchange of energy on global climate is demonstrated through El Niño events that recur on interannular timescales. However ocean circulations that modulate mixing of cold ocean interior water into the surface mixed layer have natural periods ranging from multi-decadal, through centennial, to millennial timescale. Climate variations on these timescales are to be expected as the natural ocean periods are excited through varying surface wind stress and through variations of gravity forces associated with the orbits of the Moon and major planets.

Santer and sixteen(!) coauthors (2008; hereafter S08) claim that observed temperature trends (in the tropical troposphere) are "consistent" with trends derived from General Circulation Models (GCM). This result, if correct, would seem to support the validity of greenhouse (GH) models—and thus the claim of substantial anthropogenic global warming (AGW).
However, their claim disagrees not only with an earlier analysis (Douglass et al. 2007), but also with the conclusions of an independent study (NIPCC, 2008), and with a recent report of the U.S. Climate Change Science Program (CCSP-SAP 1.1) Karl et al. 2006), which was written by some of the same authors as S08! The crucial CCSP Chapter 5 had identified a "potentially serious inconsistency" between modeled and observed trends in tropical lapse rates (Santer et al. 2006).
But S08 now claim that there are problems with the temperature data used in the CCSP report and call attention to "new observational estimates of surface and tropospheric temperature trends." They state that "there is no longer a serious discrepancy between modeled and observed trends…" Their key graph (shown here as Figure 4) conveys a (misleading) visual impression of an overlap between observations and GH model results.
I show here that no credible analysis supports the S08 claim of "consistency": The "new observational estimates" are spurious and do not agree with satellite data (as claimed by S08). I show that the wide 'spread' (range) of modeled trend values, calculated by S08, is a pure artifact that reflects the particular models' chaotic and structural uncertainties (which had been completely ignored). My conclusion, therefore, is that the claimed "consistency of modeled and observed temperature trends" does not exist.

The extent of the solar variability's climatic role is a topic of intense debate. The main reason is that if the sun is important, it can explain part of the 20th century warming, and it would imply that the climate sensitivity is on the low side, such that 21st century temperature increase due to human activity will be moderate. Here I summarize the evidence for how the sun affects the climate (primarily through modulation of the cosmic ray flux), how large the solar forcing is, and its implications to the understanding of current climate issues.

Present global and national schemes for carbon regulation often include methane alongside carbon dioxide. It is therefore important to understand the sources, sinks and control of methane in the atmosphere and then consider if methane should be part of any carbon regulation scheme. Atmospheric measurements over the last 50 years show substantial changes in methane concentration. Natural gas leakage from pipelines has been the major contributor up to 1990. For the last 15 years there has been little increase in concentration and natural climate variability has been the dominant control in changing methane concentrations.

We report on political realizations, technical and scientific progress, and international participation in countering Potentially Hazardous Objects that have the potential of colliding with Earth and inflicting enormous damage. We cover the areas of the most frequent, small (i.e., Tunguska-sized objects) as well as the most dangerous objects, the long-period comets that are usually ignored.

Given the large quantity of objects in space near Earth, there is the possibility that one of these will impact the Earth's surface. The most mature technologies for deflecting such an object so that it does not strike the Earth are the conventional means of hypervelocity impactors or chemical explosives. These methods turn out to be very effective because of momentum enhancement, which is the increase in momentum transferred to a target due to ejecta material being thrown backwards during crater formation, i.e., the objects themselves supplying some of the material that leads to the change in momentum. Quantitative estimates of momentum enhancement are of interest in determining the effectiveness of hypervelocity impactors and chemical explosives in deflecting potentially hazardous cosmic objects. This paper explores momentum enhancement both experimentally and computationally, showing that enhancements on the order of 10 are a possibility.

There are many outstanding questions about the correct response to an asteroid or comet impact threat on Earth. Nuclear munitions are currently thought to be the most efficient method of delivering an impact-preventing impulse to a potentially hazardous object (PHO). However, there are major uncertainties about the response of PHOs to a nuclear burst, and the most appropriate ways to use nuclear munitions for hazard mitigation.

As Professor Zichichi said, I have been following your activities in Erice for almost half a century. Every year, thousands of scientists present their latest discoveries and inventions here, thus promoting a Science without secrets and without borders. But you do not limit yourselves to conducting studies and research that the general public might consider purely theoretical. You caught my attention with your study of Planetary Emergencies and with your worldwide implementation of projects aimed at proving that we can address and solve these Planetary Emergencies. You have realised a hundred projects in 50 countries in order to convince us politicians that where there is a political will, Planetary Emergencies can be addressed and solved…
