Honeybees utilise floral odours when foraging for flowers; we investigated whether diesel exhaust pollution could interrupt these floral odour stimuli. A synthetic blend of eight floral chemicals, identified from oilseed rape, was exposed to diesel exhaust pollution. Within one minute of exposure the abundances of four of the chemicals were significantly lowered, with two components rendered undetectable. Honeybees were trained to recognise the full synthetic odour mix; altering the blend, by removing the two chemicals rendered undetectable, significantly reduced the ability of the trained honeybees to recognize the altered odour. Furthermore, we found that at environmentally relevant levels the mono-nitrogen oxide (NOx) fraction of the exhaust gases was a key facilitator of this odour degradation. Such changes in recognition may impact upon a honeybee’s foraging efficiency and therefore the pollination services that they provide. Read more ...

You learn the damnedest things in the damnedest places, which is a good reason to keep your ears open wherever you may be.
Last night I found myself listening to Michael Savage, easily the most offensive of all conservative talk show hosts, and he gives Rush and Mark Levine a run for their money in the ego category, too. I only listen to Savage by accident, and then only in bites of five minutes or less; it frightens me that millions of people might be influenced by such consistently hateful commentary. Read more ...

Does the Hippocratic maxim apply to the modern-day athlete?
“Do no harm” seems pretty simple. Yet, it is important to define “harm”: Is it purely physical or could it be psychological or financial?
In today’s sports medicine arena, this definition is not so clear. The traditional physician-patient relationship now has become, at the least, a triad—doctor-patient-team relationship. In some cases, the financial “health” of the patient threatens to cloud the picture. Read more ...

The Fukushima accident has brought nuclear power to the forefront of political controversy again. This controversy is particularly hard to resolve due to four specific characteristics of the risks of nuclear energy:(i) a nuclear accident has a low probability but potentially very large consequences; (ii) nuclear risk assessments are thwarted by high levels of uncertainty and even ignorance; (iii) nuclear waste remains radiotoxic for several hundred thousands of years; and (iv) nuclear technology gives rise to intense emotions by both proponents and opponents. As a consequence, traditional approaches to risk assessment no longer suffice to deal adequately with the risks of nuclear power and should be supplemented by an explicit discussion of themoral acceptability of the risks of nuclear technology.

In the first of this year's Reith Lectures, entitled Scientific Horizons, Martin Rees, President of the Royal Society, Master of Trinity College and Astronomer Royal, explores the challenges facing science in the 21st century. We are increasingly turning to government and the media to explain the risks we face. But in the wake of public confusion over issues like climate change, the swine 'flu vaccine and, more recently, Iceland's volcanic ash cloud, Martin Rees calls on scientists to come forward and play a greater role in helping us understand the science that affects us all.

Almost half of Fukushima children now have thyroid disorders from radiation poisoning, officials blame 'too much seafood'Sunday, December 02, 2012 by: PF Louis
(NaturalNews) Not much information comes out of Japan about Fukushima anymore, and the American MSM seems to have forgotten what watered down reporting they had done earlier. But the human suffering has begun in Japan, and even the Japanese government is trying to pretend it's not happening.
The curtain is pulled over the total impact of this disaster to protect the nuclear power industry. The government and media blackout has become known as "plume gate" for the radioactive plume that was released from the Fukushima mishap. Read more ...
Exposure of the heart to ionizing radiation during radiotherapy for breast cancer increases the subsequent rate of ischemic heart disease. The increase is proportional to the mean dose to the heart, begins within a few years after exposure, and continues for at least 20 years. Women with preexisting cardiac risk factors have greater absolute increases in risk from radiotherapy than other women. (Funded by Cancer Research UK and others.)

The NRC said the U.S. nuclear plant with the greatest earthquake risk is Indian Point, 24 miles north of New York City.
(CNN) -- The earthquake and tsunami in northeastern Japan on March 11 last year took an estimated 19,000 lives, caused the evacuation of about 300,000 people, and set off the worst nuclear accident since Chernobyl. The meltdowns of the Fukushima Daiichi reactors ended Japan's plans to produce half of its electricity through nuclear energy.
All of Japan's remaining reactors are offline, and experts believe that strong anti-nuclear feelings will keep them from restarting for some time. Beyond Japan's shores, the crisis has pushed Germany, Italy and Switzerland to end their commitment to nuclear power. Fukushima has given U.S. nuclear regulators four important lessons given a tendency to downplay the far-reaching consequences of disasters and outdated ways of preparing for them. Read more ...
Resignation and Retirement Result
The long-awaited review of a controversial study on the drilling process known as hydraulic fracturing, or “fracking,” was released today, and it finds numerous errors and flaws with how the study was conducted and released, as well as University of Texas policies for disclosing conflicts of interest.
The head author of the study, Dr. Charles “Chip” Groat, has retired in the wake of the controversy, and the head of the Energy Institute that released it, Dr. Raymond Orbach, has resigned as head of the Institute, the University announced today. Listen to it.

The collapse of the Fukushima Dai-ichi Nuclear Power Plant caused a massive release of radioactive materials to the environment. A prompt and reliable system for evaluating the biological impacts of this accident on animals has not been available. Here we show that the accident caused physiological and genetic damage to the pale grass blue Zizeeria maha, a common lycaenid butterfly in Japan. We collected the first-voltine adults in the Fukushima area in May 2011, some of which showed relatively mild abnormalities. The F1 offspring from the first-voltine females showed more severe abnormalities, which were inherited by the F2 generation. Adult butterflies collected in September 2011 showed more severe abnormalities than those collected in May. Similar abnormalities were experimentally reproduced in individuals from a non-contaminated area by external and internal low-dose exposures. We conclude that artificial radionuclides from the Fukushima Nuclear Power Plant caused physiological and genetic damage to this species.(a) Collection localities. A red dot indicates the location of the Fukushima Dai-ichi NPP. Black dots and black half dots indicate the cities from which the first-voltine adults were collected. Brown dots and brown half dots indicate cities from which the host plant leaves were collected for the internal exposure experiment. All experiments were performed in Okinawa, marked by a blue dot.

LOS ANGELES (AP) — Across the vast Pacific, the mighty bluefin tuna carried radioactive contamination that leaked from Japan's crippled nuclear plant to the shores of the United States 6,000 miles away — the first time a huge migrating fish has been shown to carry radioactivity such a distance.
"We were frankly kind of startled," said Nicholas Fisher, one of the researchers reporting the findings online Monday in the Proceedings of the National Academy of Sciences.
The levels of radioactive cesium were 10 times higher than the amount measured in tuna off the California coast in previous years. But even so, that's still far below safe-to-eat limits set by the U.S. and Japanese governments. Read more ...
CT scans expose children to radiation that could give them cancer, according to a review of children’s imaging data published Wednesday in the British medical journal Lancet.
The researchers estimate that for every 10,000 computed tomography scans performed on children aged 10 or younger, one additional child will get a brain tumor and another additional child will get leukemia within a decade of the first scan. These cancers wouldn’t otherwise be expected, even if none of the imaging was done.
Researchers at the National Cancer Institute and Institute of Health and Society at Newcastle University in England say their investigation is the first direct evidence of such a link. They reviewed 175,000 cases.
Multiple CT scans increase a child’s risk. The researchers found radiation exposure from two to three scans can triple the risk of brain cancer and five to ten scans can triple the risk of leukemia. Read more ...

(CNN) -- The news last week was all about Facebook's dodgy IPO. Investors are filing suit against Facebook about withholding "negative" assessment on its business prospects. This IPO not only "Zucked up" Silicon Valley's supposed tech bubble, but it has created the suspicion that Facebook willfully exploited the innocence of the small investor.
But something even dodgier than a potential stock market fraud is going on. The social network is taking something much more important than money from its nearly one billion members. By sabotaging what it really means to be human, Facebook is stealing the innocence of our inner lives. Read more ...
Enron, Worldcom, Bernie Madoff, the subprime mortgage crisis.
Over the past decade or so, news stories about unethical behavior have been a regular feature on TV, a long, discouraging parade of misdeeds marching across our screens. And in the face of these scandals, psychologists and economists have been slowly reworking how they think about the cause of unethical behavior.
In general, when we think about bad behavior, we think about it being tied to character: Bad people do bad things. But that model, researchers say, is profoundly inadequate.
Which brings us to the story of Toby Groves. Listen to it.

(CNN) -- Six decades ago, Charlie Follett was a teenager living in California's Sonoma State Home. As he did most days, Follett sat in a field, singing popular songs to himself, enjoying the sunshine and the solitude.
Suddenly, someone came outside to get Follett and brought him to the hospital. They told him to lie down on an operating table, and then the needle came out.
"First, they shot me with some kind of medicine. It was supposed to deaden the nerves," he said. "Then the next thing I heard was snip, snip, and that was it." Read more ...
November 8, 2011 NASA's next Mars rover, Curiosity, seen in this artist's rendering, will use 8 pounds of plutonium-238 as its power supply. That's a significant portion of the remaining space fuel. NASA and the Department of Energy have offered to split the costs of producing the fuel, but Congress has so far opposed that arrangement.
When NASA's next Mars rover blasts off later this month, the car-sized robot will carry with it nearly eight pounds of a special kind of plutonium fuel that's in short supply.
NASA has relied on that fuel, called plutonium-238, to power robotic missions for five decades.
But with supplies running low, scientists who want the government to make more are finding that it sometimes seems easier to chart a course across the solar system than to navigate the budget process inside Washington, D.C. Read more ...

It was April Fool's Day, 1979—30 years ago this month—when Randall Thompson first set foot inside the Three Mile Island nuclear power plant near Middletown, Pa. Just four days earlier, in the early morning hours of March 28, a relatively minor problem in the plant's Unit 2 reactor sparked a series of mishaps that led to the meltdown of almost half the uranium fuel and uncontrolled releases of radiation into the air and surrounding Susquehanna River.

"Doubt is our product," a cigarette executive once observed, "since it is the best means of competing with the 'body of fact' that exists in the minds of the general public. It is also the means of establishing a controversy."
In this eye-opening exposé, David Michaels reveals how the tobacco industry's duplicitous tactics spawned a multimillion dollar industry that is dismantling public health safeguards. Product defense consultants, he argues, have increasingly skewed the scientific literature, manufactured and magnified scientific uncertainty, and influenced policy decisions to the advantage of polluters and the manufacturers of dangerous products.
