Here's the summary: President Obama’s Blueprint for a Clean and Secure Energy Future
The United States is on the path to a cleaner and more secure energy future. Since President Obama took office, responsible domestic oil and gas production has increased each year, while oil imports have fallen to a 20-year low; renewable electricity generation from wind, solar, and geothermal sources has doubled, and the amount of energy our economy wastes has continued to decline; clean energy manufacturing is creating new jobs in industries like solar and wind, and technology and production costs are dropping because of discoveries in the lab and innovation on the factory floor. The President’s “all-of-the-above” approach to develop every source of American energy – expanding oil and gas production and investing in new clean energy technologies – is working. It’s a winning strategy for the economy, energy security, and the environment.
Thomas G. Bourgeois, deputy director of Pace University’s Energy and Climate Center, provided this response for the Dot Earth blog when asked, after the Hurricane Sandy disaster, how distributed generation of electricity and heat could cut disaster impacts and mesh with efforts to develop renewable energy sources in cities.

Bullying—long tolerated as just a part of growing up—finally has been recognized as a substantial and preventable health problem. Bullying is associated with anxiety, depression, poor school performance, and future
delinquent behavior among its targets, and reports regularly surface of youth who have committed suicide at least in part because of intolerable bullying. Bullying can also have harmful effects on children who bully, on
bystanders, on school climates, and on society at large. Bullying can occur at all ages, from before elementary school to after high school. It can take the form of physical violence, verbal attacks, social isolation, spreading
rumors, or cyber bullying.
Increased concern about bullying has led 49 states and the District of Columbia to enact anti-bullying legislation since 1999. In addition, researchon the causes, consequences, and prevention of bullying has expanded greatly in recent decades. However, major gaps still exist in the understanding of bullying and of interventions that can prevent or mitigate the effectsof bullying.
This publication examines reviewed research on bullying
prevention and intervention efforts as well as efforts in related areas of research and practice, implemented in a range of contexts and settings, including

Can health equity survive epidemiology? Standards of proof and social determi...Jim Bloyd, DrPH, MPH
Objective. This article examines how epidemiological evidence is and should be used in the context of increasing concern for health equity and for social determinants of health.
Method. A research literature on use of scientific evidence of “environmental risks” is outlined, and key issues compared with those that arise with respect to social determinants of health.
Results. The issue sets are very similar. Both involve the choice of a standard of proof, and the corollary need to make value judgments about how to address uncertainty in the context of “the inevitability of being wrong,” at least some of the time, and to consider evidence from multiple kinds of research design. The nature of such value judgments and the need for methodological pluralism are incompletely understood.
Conclusion. Responsible policy analysis and interpretation of scientific evidence require explicit consideration of the ethical issues involved in choosing a standard of proof. Because of the stakes involved, such choices often become contested political terrain. Comparative research on how those choices are made will be valuable.

Patient advocate Stephen Dolle's letter to FDA Larry Kessler to add key action items to the 1999 STAMP Conference report regarding problems with CNS shunts, and to address the FDA ruling on his 1996 anti siphon shunt petition FDA granted. The STAMP Conference turned out to be a complete sham and major device failures continued with CNS shunts under Larry Kessler, Janine Morris, and others at FDA, which Dolle attributes to the poor state of affairs of hydrocephalus treatment today. As author of the FDA petition that caused STAMP, Dolle was not invited on its panel, nor was his new mHealth DiaCeph Test included in STAMP.

The Refinery Platform (http://www.refinery-platform.org) is a web-based data visualization and analysis system for epigenomic and genomic data designed to support reproducible biomedical research. The analysis backend employs the Galaxy Workbench and connects to a data repository based on the ISA-Tab data description format. In my talk I will discuss the exploratory visualization tools that we have integrated into Refinery.
Science builds on itself, and the enormous scientific progress of the last several centuries has been due largely to the trust that scientists place in one another and the trust the public places in scientists. I explore the responsibility that researchers have toward one another and to the world at large.

REFRAMING CLIMATE JUSTICE FOR DEVELOPMENT: SIX PRINCIPLES FOR SUPPORTING INCLUSIVE AND EQUITABLE ENERGY TRANSITIONS IN LOW-EMITTING ENERGY-POOR AFRICAN COUNTRIES
By Mimi Alemayehou, Katie Auth, Murefu Barasa, Morgan Bazilian, Brad Handler, Uzo Iweala, Todd Moss, Rose Mutiso, Zainab Usman
Advancing inclusive and equitable energy transitions is one of this century’s most vital global challenges, and one in which development finance will play a crucial role. References to justice and equity are widespread in international climate policy, and are increasingly being used by development organizations to guide their own work, including support for energy transitions.
But prevailing definitions of climate justice rarely fully capture the priorities, challenges and perspectives of low-emitting energy-poor countries, the vast majority of which are in sub-Saharan Africa. When applied to development policy, this gap risks prioritizing near-term emissions reductions over broader support for economic development and energy transformation, with comparatively little climate benefit. This could severely hinder poverty alleviation, development, and climate resilience — the very opposite of justice. We need energy transitions that are truly ‘just and inclusive.’ What does this mean for development funders and financiers, and how should it drive their approach to supporting energy transitions in the lowest-income countries?

Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.

Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
These lecture slides, by Dr Sidra Arshad, offer a quick overview of physiological basis of a normal electrocardiogram.

Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

A Defense of Presenting Fracking Health Risk Data Ahead of Peer review
1. This is a response from Sandra Steingraber, distinguished scholar in residence at
Ithaca College, to the Dot Earth post “When Publicity Precedes Peer Review in the
Fight Over Gas Impacts”:
Your recent blog compares and contrasts the claims made by industry-funded reports on
the risks of fracking with those made by academic scientists who speak about their data
in advance of publication. In so doing, you imply there is an equivalency of bias or
motivation.
There is not.
Polluting industries have long ministered to their particular public relations problems and
sought to delay regulatory action (or outright prohibition) by underwriting studies and
reports -- and sometimes entire university-based institutes. The resulting publications
almost never find serious evidence for harm. In the field of environmental health, we
refer to these efforts as "cigarette science."
Throughout several decades of the 20th century, for example, the lead paint industry
funded researchers to investigate the effect of their product on the brain development of
children. Not surprisingly, this research uncovered few serious problems. At the same
time, the industry denounced independent research that did find serious problems as anti-
lead propaganda. (At one point, the industry argued, based on its research, that the
problem was not that the consumption of lead paint made children stupid but that stupid
children ate paint.)
I think filmmaker Josh Fox is exactly right to say, as he does in The Sky is Pink, that gas
industry denials of harm fit into the narrative template of the tobacco story. (We could
also call it the lead paint story. Or the asbestos story. Or the PCB story. Or the DDT
story. See David Gee, Late Lessons from Early Warnings.)
On the other hand, academic researchers who are not on the payroll of industry and who
are trying in good faith to understand the possible public health effects of a new
technology -- which is being unrolled without advance demonstration of safety -- can
sometimes find results that are frightening enough to warrant immediate public
conversation.
This is the story of Elaine Hill, the young Ph.D. student from Cornell who has conducted
the first population-based, observational study of the public health effects of fracking.
Andrew, I would like you to place yourself in her shoes for a minute.
Suppose you took a close look at hospital data on newborn health before and after drilling
and fracking operations arrived in communities (in states where the shale gas boom is
booming away). Suppose you mapped the locations of individual gas wells, looked at the
distance between the wells and the homes where the mothers of those babies lived during
their pregnancies. Suppose you analyzed the data carefully. Suppose you found
significant effects -- bigger even than the impact of cigarette smoking on newborn health.
2. Suppose you took every care to eliminate confounding variables and still believed that
you had evidence to suggest that newborn babies were being harmed by fracking
operations. At the very least, your research seems to raise serious questions in urgent
need of answers.
Now suppose that you happen to live in a state where fracking is not allowed. Suppose it
appears, however, that the governor of your state is giving every indication that he is
preparing to life the moratorium -- even though no a priori attempt has been made to
evaluate the impact of fracking on public health.
Suppose it becomes clear that the governor is going to make his decision before your
research can wend its way through the peer review process and get published.
Suppose you've already presented your findings at two academic conferences and in one
poster presentation and that it has been warmly received by your academic colleagues.
Suppose you have an opportunity to present your research to the public -- and to your
state's senators -- in advance of the governor's decision.
Would you take it? Could you look at yourself in the mirror if you did not? And would
you sabotage your academic career if you did?
Let me say clearly -- as I did in my own Senate testimony -- that I was the one who
suggested to Elaine that she consider testifying. As you quoted me in saying, I think she
made a brave and ethical decision.
At the same time, let me also say -- and I think I speak for Elaine Hill as well -- that I'm a
big believer in peer review. Most academic researchers are. But there can't be double
standards. If peer review is required for all public utterances and assertions about the
possible environmental and health effects of fracking, then let's strip all the non-peer
review studies from the 1,537-page planning document for fracking -- the supplemental
generic environmental impact statement (sGEIS) -- that is the science on which will rest
Governor Cuomo's upcoming decision to permit or prohibit fracking.
If we need to wait for data to be peer reviewed before we act on it -- which is a great idea
-- then we need to maintain New York's moratorium on fracking while Hill's data, and the
other health effects studies now in the planning stage, make their way into a peer-
reviewed journals. The sGEIS itself needs to be sent out for peer review.
If the Governor permits fracking on the basis of an sGEIS full of unvetted, un-peer-
reviewed data, then he can't say the decision was based on science.
Right?
Andrew, take a close look at sGEIS's references. If all the non-peer reviewed citations
were removed from the analysis and its bibliographies, I estimate that the document
3. would be 60-80 percent shorter. At least.
I especially invite you and your readers to examine the bibliographic entries for the
section of the sGEIS entitled, “Human Health Risk Evaluation for Hydraulic Fracturing
Additives.” Not one medical journal or peer-review study informs the conclusion that
public health risk assessments are unnecessary. Instead, what lies behind the document's
dismissive assertion that exposure pathway are geological impossibilities is a list of
industry journal articles and "fact sheets." Not peer-reviewed data.
Tellingly, the first item in that bibliography is a document from the petroleum industry.
The revised draft sGEIS is the worst scientific review I've ever seen.
I’ve served on President Clinton’s National Action Plan on Breast Cancer and as science
advisor to a couple of public research initiatives, including the California Breast Cancer
Research Program. I’ve testified before the President’s Cancer Panel, helped review
literature while in residence at Cornell University's Program on Breast Cancer and
Environmental Risk Factors, and am a co-editor of the University of California
report Identifying Gaps in Breast Cancer Research
(http://cbcrp.org/sri/reports/identifyingGaps/GAPS_full.pdf), which is a 510-page, fully-
referenced science review.
In all cases, I spent a lot of time looking at peer-reviewed data. Indeed, during the two
years I worked on the mammoth California breast cancer report, all the chapters I edited
-- which were based on peer-reviewed studies -- were themselves sent out for peer
review. And then they were revised and re-edited.
This is not even close to the process that has guided the creation of the sGEIS.
So, if -- on the grounds that it is bad form to present data in advance of peer review -- you
criticize my decision to encourage Elaine Hill to present, before a panel of New York
senators, her preliminary research on the impact of drilling and tracking operations on
infant health, then I also expect to hear from you a call to withdraw the un-peer-reviewed
sGEIS on the grounds that it is not science.
The wheels of scientific proof-making grind slowly and with discernment. The decision
to roll out drilling and fracking across the nation proceeds at the frenzied and
undiscerning pace of a gold rush. What would you have us researchers do? Stay silent
until our data appears in print -- even if we have reason to believe that lives are at risk?
Or insert ourselves into the political process?
It would help all concerned -- not the least of whom are newborns -- if journalists like
you would call on the political decision-making to slow down so that the science can
catch up rather than attack researchers who choose to speak their conscience rather than
remain silent in the face of a headlong rush to drill and frack.
