US plan to cut growth in energy use by at least 50% by 2025


More than 60 energy, environmental and other organizations have collaborated on a new report that could save Americans more than $500 billion in energy costs over 25 years and reduce annual greenhouse gas emissions equivalent to those from 90 million vehicles.

The National Action Plan for Energy Efficiency Vision for 2025 provides a framework for states, utilities and other stakeholders to achieve the following by 2025:

  • More than $100 billion in lower energy bills


  • Annual energy savings exceeding 900 billion KWh. Equivalent to over 50 GW of power, or more than 100 500 MW power plants over 20 years.


  • Generate over $500 billion of total net savings.

Group selection: A fresh approach to evolution

The Quarterly Review of Biology will publish a landmark paper in December written by two giants in sociobiology, David Sloan Wilson and Edward O. Wilson.

The paper “Rethinking the Theoretical Foundation of Sociobiology,” proposes a new consensus and theoretical foundation that affirms Darwin’s original conjecture and is supported by the latest biological findings.

Wilson and Wilson trace much of the confusion in the field to the 1960’s, when most evolutionists rejected “for the good of the group” thinking and insisted that all adaptations must be explained in terms of individual self-interest. In an even more reductionistic move, genes were called “the fundamental unit of selection,” as if this was an argument against group selection. Scientific dogma became entrenched in popular culture with the publication of Richard Dawkins’ The Selfish Gene (1976). Although evidence in favor of group selection began accumulating almost immediately after its rejection, its taboo status prevented a systematic re-evaluation of the field until now.

Based on current theory and evidence, Wilson and Wilson show that natural selection is unequivocally a multilevel process, as Darwin originally envisioned, and that adaptations can evolve at all levels of the biological hierarchy, from genes to ecosystems.

Disproving Einstein's Blunder


Texas A&M researchers Nicholas Suntzeff and Kevin Krisciunas are part of the ESSENCE project that has been studying supernovae since 2002 in an attempt to prove or disprove Einstein's self-proclaimed “biggest blunder” – his postulation of a cosmological constant (λ).

The international team is studying supernovae to figure out if dark energy (the accelerating force of the universe) is consistent with Einstein’s cosmological constant.

“The magic value is -1 exactly. If the number turns out to be precisely -1, then this dark energy is a relatively simple thing – it is Einstein’s cosmological constant.” -- Kevin Krisciunas

The team won’t have the final results until later next year, but according to Suntzeff, the measurement is coming in at -1 plus or minus 10 percent error, so the initial data seems to point to Einstein being correct.

In 1917, Einstein was working on his Theory of General Relativity and was trying to come up with an equation that describes a static universe – one that stands still and does not collapse under the force of gravity. In order to keep the universe static in his theory, Einstein introduced a cosmological constant – a force that opposes the force of gravity.

  • 12 years later, Edwin Hubble discovered that the universe is not static – it is actually expanding. So Einstein scrapped his idea of a cosmological constant and dismissed it as his biggest blunder.

    In 1998, two teams of scientists, one of which Suntzeff co-founded, discovered that the universe is not only expanding, but its expansion is actually accelerating. This observation formed the basis of dark energy: A force that not only overcomes gravity but is driving the universe into an exponential acceleration.

    T-Rays to replace X-Rays in security and medicine

    The U.S. Department of Energy's Argonne National Laboratory along with collaborators in Turkey and Japan, have created a compact source of T-rays.


    Until now T-rays (or terahertz radiation) could not be generated by conventional solid-state electrical circuits. Having a compact, cost-effective source of terahertz radiation will enable commercial application of T-Rays in both security and medicine.

    Unlike far more energetic X-rays, T-rays do not have sufficient energy to "ionize" an atom by knocking loose one of its electrons. This ionization causes the cellular damage that can lead to radiation sickness or cancer. Since T-rays are non-ionizing radiation, like radio waves or visible light, people exposed to terahertz radiation will suffer no ill effects. Furthermore, although terahertz radiation does not penetrate through metals and water, it does penetrate through many common materials, such as leather, fabric, cardboard and paper.

    These qualities make terahertz devices one of the most promising new technologies for airport and national security. Unlike today's metal or X-ray detectors, which can identify only a few obviously dangerous materials, checkpoints that look instead at T-ray absorption patterns could not only detect but also identify a much wider variety of hazardous or illegal substances.

    T-rays can also penetrate the human body by almost half a centimeter, and they have already begun to enable doctors to better detect and treat certain types of cancers, especially those of the skin and breast, Welp said. Dentists could also use T-rays to image their patients' teeth.


    The new T-ray sources created at Argonne use high-temperature superconducting crystals grown at the University of Tsukuba in Japan. These crystals comprise stacks of so-called Josephson junctions that exhibit a unique electrical property: when an external voltage is applied, an alternating current will flow back and forth across the junctions at a frequency proportional to the strength of the voltage; this phenomenon is known as the Josephson effect.

    These alternating currents then produce electromagnetic fields whose frequency is tuned by the applied voltage. Even a small voltage – around two millivolts per junction – can induce frequencies in the terahertz range, according to Welp.

    Since each of these junctions is tiny – a human hair is roughly 10,000 times as thick – the researchers were able to stack approximately 1,000 of them on top of each other in order to generate a more powerful signal. However, even though each junction would oscillate with the same frequency, the researchers needed to find a way to make them all radiate in phase.

    What the IAEA really said about Iran

    The United Nations International Atomic Energy Agency (IAEA) has filed its latest report on the implementation of safeguards and relevant provisions of Security Council resolutions in the Islamic Republic of Iran.


    Timeline leading up to the current report

    In December 2006 and again in March 2007 the UN Security Council passed resolutions requiring Iran to comply with the Nuclear Non Proliferation Treaty (NPT) and urging it to implement a number of safeguards in its nuclear program.

    In June 2007 IAEA Director General Mohamed ElBaradei outlined that "diplomacy and negotiation" provided the only durable solution for the implementation of safeguards and relevant provisions of Security Council resolutions in Iran.

    In the months from June to August a number of IAEA inspections were carried out along with meetings and interviews with officials and technicians involved in Iran's nuclear program.

    On 27 August, the IAEA Secretariat released the text of a work plan agreed between Iran and the IAEA titled "Understandings of the Islamic Republic of Iran and the IAEA on the Modalities of Resolution of the Outstanding Issues."

    On 30 August, Director ElBaradei released a report on the implementation of the NPT safeguards. This contained a number of outstanding questions that required actioning.

    On 15 November, ElBaradei circulated the current report to the IAEA Board of Governors on the Implementation of the NPT Safeguards Agreement and relevant provisions of Security Council resolutions in the Islamic Republic of Iran.

    The findings of the current IAEA report

    • The work plan agreed by the Secretariat and Iran in August, in which Iran has finally committed itself to address the outstanding issues relevant to its nuclear activities, is proceeding according to schedule.


    • As the report makes clear - the scope and nature of Iran´s centrifuge enrichment activities - there has been good progress in connection with the verification of Iran´s past acquisition of P-1 and P-2 centrifuge enrichment technologies. The Agency has concluded that the information provided by Iran in that regard is consistent with the Agency´s own investigation.


    • Verification of the uranium particle contamination at a technical university, as well as the alleged studies and other activities that could have military applications, will, in accordance with the work plan, take place over the next several weeks.


    • The Agency will also continue to seek corroboration and verification of the completeness of Iran´s declarations concerning its nuclear material and activities as per the agreed work plan.


    • The IAEA's knowledge about specific aspects of Iran´s current programme has diminished since 2006, when Iran ceased to provide the Agency with information under the additional protocol and additional transparency measures.


    • Progress over the past two months has been made possible by an increased level of cooperation on the part of Iran, in accordance with the work plan.

    With regard to Iran´s current nuclear activities, we have been able to verify the non-diversion of all declared nuclear material. We also have in place a safeguards approach for the Natanz facility that enables us to credibly verify all enrichment activities there.

    However, as with all States that do not have an additional protocol in force, we are unable to provide credible assurance about the absence of undeclared nuclear material and activities. This is especially crucial in the case of Iran, because of its history of undeclared activities, and the corresponding need to restore confidence in the peaceful nature of Iran´s nuclear programme.

    I urge Iran, therefore, to resume without delay the implementation of the additional protocol. The Agency needs to have maximum clarity not only about Iran´s past programme but, equally or more important, about the present. I should note, however, that the Agency has no concrete information about possible undeclared nuclear material or weaponization activities in Iran, other than the outstanding issues I have already mentioned.

    Scientists recreate embryonic stem cells from regular skin cells

    A team of University of Wisconsin-Madison researchers reports the genetic reprogramming of human skin cells to create cells indistinguishable from embryonic stem cells.

    James Thomson, Junying Yu and colleagues introduced a set of four genes into human fibroblasts; skin cells that are easy to obtain and grow in culture. This induced the cells into what scientists term as a pluripotent state: A condition that is essentially the same as that of embryonic stem cells.

    Using these reprogramming techniques, the Wisconsin group has developed eight new blank slate stem cells capable of becoming any of the 220 types of cells in the human body. Some of these new cell lines have now been growing continuously in culture for as long as 22 weeks.

    When perfected, the new technique would bring stem cells within easy reach of many more scientists as they could be easily made in labs of moderate sophistication, and without the ethical and legal constraints that now hamper their use by scientists.

    This paper will appear in the Dec. 21, 2007 print edition of the journal Science.

    UW bioethicist R. Alta Charo says that the scientific finding could have far-reaching effects on the social dimensions of the ongoing controversy over embryonic stem cell research.
    "This is a method for creating a stem cell line without ever having to work through, at any stage, an entity that is a viable embryo. Therefore, you manage to avoid many of those debates with the right-to life community."

    FCC grants more wishes on 700MHz band

    In addition to measures to open up the 700MHz spectrum as per Google's requests, the FCC has just agreed to remove the restrictions on how much of the D-Block portion of the spectrum can be put up for wholesale by the winner.
    To encourage the widest range of potentially qualified applicants to participate in bidding for the D Block license, we enabled eligible bidders for this license to seek designated-entity bidding credits for small businesses, as a means to create incentives for investors to provide innovative small businesses with the capital necessary to compete for the D block license at auction -- FCC

    This move will significantly bolster the abilities of entrepreneurial businesses like Frontline Wireless in securing spectrum for their nationwide "4G" wireless network.

    The 700MHz spectrum explained


    • The D-Block portion of the spectrum (purple) lies adjacent to the two portions of spectrum reserved for public safety use. The winner of the D-Block auction will be required to "build out a nationwide wireless network that is good enough to meet public safety specifications for coverage and redundancy." The payoff for the D-Block winner is that they will get to use the public safety channels for commercial purposes while they are not being used; significantly increasing their overall bandwidth.


    • The C-Block portion of the spectrum (yellow) covers the 22MHz that Google has indicated may bid the FCC's reserve price of $4.5B on. This is the prime "beach front" real estate the likes of Verizon would like to control. Google CEO Eric Schmidt told reporters last month that Google may team with another company to bid for this portion of the spectrum. Analysts are predicting that this could be someone like Sprint, who have already partnered with Google to provide the wireless Internet service WiMax in 2008.


    • The A and B portions have already been auctioned off.

    IPCC publishes its fourth assessment report

    Human readable IPCC report without the media hype, politics or scientific gobbledygook:
    1. Earth has warmed 0.74°C in the last 100 years

    2. Sea level has risen on average between 1.8mm and 3.8mm per year since 1961

    3. Snow and ice cover has been shrinking by 0.27% every year since 1978

    4. In the last 100 years, rains increased in some parts of the world and decreased in others. It is unclear however if drought has increased overall.
    5. It is likely that cold days have become less frequent and warm days more frequent in the last 50 years

    6. It is difficult to tell if intense tropical cyclone activity has increased since 1970



    Observed changes in (a) average temperature; (b) average sea level and (c) Northern Hemisphere snow cover for March-April. All differences are relative to 1961-1990 averages. The shaded areas mark the uncertainty in the data.

    1. Atmospheric concentrations of greenhouse gasses in 2005 far exceed the natural range over the last 650,000 years. These increases are due primarily to fossil fuel.

    2. Most of the observed increase in temperatures in the last 50 years is very likely due to the observed increase in greenhouse gasses.



    Global annual emissions of human-caused greenhouse gasses from 1970 to 2004.5

    1. Current governmental policies are highly likely to allow greenhouse gas emissions to grow over the next few decades.

    2. Continued greenhouse gas emissions at or above current rates would cause further warming effects larger than those observed during the last 100 years



    The solid lines are averages of surface warming for various possible scenarios from worst-case (red) to best case (blue). The uncertainty is shown in the shaded areas. The bars at the end show the likely range of temperature increases in the 100 year period after 2100. All temperatures are relative to today.

    Conclusions


    • In the next 100 years temperature will rise between 1.8°C and 4.0°C over today.


    • The sea level will rise between 0.2m and 0.6m (between 0.6 and 1.9 feet) in the next 100 years

    Scientists develop a direct neural interface

    Scientists say they may be on the brink of translating the thoughts of a man who can no longer speak into words after a pioneering experiment.

    Electrodes have been implanted in the brain of Eric Ramsay, who has been "locked in" - conscious but paralysed - since a car crash eight years ago.

    Although the data is still being analysed, researchers at Boston University believe they can correctly identify the sound Mr Ramsay's brain is imagining some 80% of the time.

    In the next few weeks, a computer will start the task of translating his thoughts into sounds.

    An Exceptionally Simple Theory of Everything

    Freelance Physicist, A. Garrett Lisi has come up with a simple and elegant Grand Unified Theory (GUT) based on the beautiful geometry of the only recently understood E8 manifold.


    Lisi's theory successfully unifies the Standard Model and General Relativity into a single testable framework; describing how all the fields of the standard model and gravity interact with each other; as well as predicting 18 new particles that can be verified as early as next year when the Large Hadron Collider (LHC) comes online in Geneva.

    The theory uses the principal bundle geometry of E8 and its curvature to model the Universe and reproduce all known fields and dynamics through pure geometry. This is in contrast to String Theory, which relies on elaborate structures of branes and orbifolds using a number of contrived assumptions.

    The theory represents a comprehensive unification program, describing all fields of the standard model and gravity as parts of a uniquely beautiful mathematical structure -- Lisi

    Lee Smolin at the Perimeter Institute for Theoretical Physics in Waterloo, describes Lisi's work as "one of the most compelling unification models I've seen in many, many years."

    The theory is not without its skeptics, but most physicists seem content to to wait until the theory can produce results testable by LHC to see which theory, if any, wins.


    Some aspects of this theory are not yet completely understood, and until they are it should be treated with appropriate skepticism. However, the current match to the standard model and gravity is very good. Future work will either strengthen the correlation to known physics and produce successful predictions for the LHC, or the theory will encounter a fatal contradiction with nature. The lack of extraneous structures and free parameters ensures testable predictions, so it will either succeed or fail spectacularly. If E8 theory is fully successful as a theory of everything, our universe is an exceptionally beautiful shape. -- Lisi

    Niels Bohr Institute publishes study on Global Warming

    The Ice and Climate Research Group at the Niels Bohr Institute of the University of Copenhagen published a benchmark study in Science (Vol. 317, no. 5839), which investigates data from the 3.2km deep Dome C ice core taken in East Antarctica. The study provides an unprecedentedly clear view of the climate record from 800,000 years ago to the present day.

    Highly correlated with the 120,000 year core taken in Dronning Maud Land in Greenland, this study will serve as a benchmark for future Climate Change research.

    Conclusions


    • Early interglacial periods were characterized by less pronounced warmth than those of the past four climatic cycles. The rainbow colors represent temperature from blue (9° colder than today) to red (4.5° warmer than today).



    • The study suggests that interplay between obliquity (the tilt of the Earth's axis as shown by the red line on the graph) and precession (change in the position of the Earth's pole as shown by the black line on the graph) accounts for the variable intensity of interglacial periods in the ice core records.



    • CO2 and CH4 (greenhouse gas) over the past 650,000 years seem to lag behind Antarctic and tropical temperature changes rather than preceed them.

    Bacterial cells produce abundant hydrogen from wastes


    Researchers from Pennsylvania State University have coaxed common bacteria to produce hydrogen in a new, efficient way.

    Bruce Logan and colleagues at Penn State University have created a modified Microbial Fuel Cell (MFC) capable of converting waste products into hydrogen gas at efficiency rates of up to 82%; paving the way for sustainable hydrogen production from any type of biodegradable organic matter.

    By using common exoelectrogenic bacteria in specially designed reactors with the addition of a small voltage to the circuit, hydrogen gas was produced at the rate of 1.1 m3 per cubic meter of reactor per day. The efficiency of the process is far in excess of the next leading alternative fuel, ethanol, which has at best a 50% overall energy efficiency; at worst a negative gain.

    Google thinks green to power its business

    To reach its goal of creating 50 megawatts of renewable generating capacity for its operations by 2012, Google is looking into the use of various forms of renewable energy.

    Clean and affordable energy is a growing need for our company, and we’re excited about the opportunity to help create competitive green alternatives. Our new initiative isn’t just about Google’s energy needs; we're seeking to accelerate the pace at which clean energy technologies are developing, so they can rival the economics of coal quickly. We've gained expertise in designing and building large-scale, energy-intensive facilities by building data centers that lead the industry in efficiency. We want to apply the same creativity and innovation to the challenge of generating inexpensive renewable electricity at scale.

    Cosmic Background Radiation Possibly Flawed


    Dr. Gerrit Verschuur, Adjunct Professor of Physics at the University of Memphis, has noticed a disturbing correlation between the small-scale structures in the Cosmic Background Radiation (CMB) and data from his All Sky Survey of Interstellar Neutral Hydrogen (HI.)

    The Nobel Winning COBE and it's successor, WMAP were designed to detect faint variations in the CMB signals left over from the Big Bang. The age and composition of the Universe has been predicted from the small-scale structure observed in this data.

    However, if even a small fraction of the anisotropy can be associated with structure in the Milky Way, the cosmological interpretations of the data could be called into question.

  • Verschuur, a pioneer in the science of radio astronomy, has been studying the properties of the Milky Way using interstellar HI for almost 50 years. According to his recent work, it appears that many of the small-scale structures observed by WMAP are correlated with HI.

    If confirmed, Verschuur's discovery means that the structure superimposed on the CMB is produced in the Milky Way and does not have a cosmic origin. Thus the CMB signal from the early universe may be smoother than anyone expected, which raises new questions as to how structure ever emerged in the Universe to create galaxies.

    Yellowstone supervolcano on the rise


    The Yellowstone supervolcano rose at a record rate since mid-2004, likely because a Los Angeles-sized, pancake-shaped blob of molten rock was injected 6 miles beneath the slumbering giant, University of Utah scientists report in the journal Science.

    The upward movement of the Yellowstone caldera floor - almost 3 inches (7 centimeters) per year for the past three years - is more than three times greater than ever observed since such measurements began in 1923, says the study in the Nov. 9 issue of Science by Smith, geophysics postdoctoral associate Wu-Lung Chang and colleagues.

    "Our best evidence is that the crustal magma chamber is filling with molten rock," Smith says. "But we have no idea how long this process goes on before there either is an eruption or the inflow of molten rock stops and the caldera deflates again," he adds.

This eruption released energy equivalent to about one gigaton of TNT and reduced the average global temperature by 5 degrees Celsius for several years.

    Dead Certain and the Terror Presidency


    The New York Times has an excellent review of two new books: Dead Certain by Robert Draper and The Terror Presidency by Jack Goldsmith

    Draper was given extraordinary access to president Bush and other members of the Executive; and has as a result written a shocking and revealing biography of Bush in his book “Dead Certain;” the title reflecting Bush's relentless denial of the facts in favor of his own strongly held beliefs.
    When “Mission Accomplished” turned sour in Iraq, when various supposed benchmarks of success did not stop the bloodshed, the president remained utterly confident of victory. He was sure, Draper writes, that “history would acquit him.”

    Goldsmith's book "The Terror Presidency" deals with issues Draper does not discuss: Bush's policies on the use of torture.
    Goldsmith is a conservative Harvard law professor who was assistant attorney general in charge of the Justice Department’s Office of Legal Counsel for nine months in 2003-4. That is where official government opinions on the law are prepared.

    John Yoo, a deputy assistant attorney general in the office, prepared the 2002 opinion defining torture narrowly and asserting that the president had supreme power to order its use. Goldsmith withdrew that opinion and replaced it with a much more modest one. It took courage to do that, because he was treated as a traitor by some in the administration — notably David Addington, then Vice President Cheney’s counsel, now his chief of staff. And it has taken courage to write this book.
