In the past few decades, the fortunate among us have recognised the hazards of living with an overabundance of food (obesity, diabetes) and have started to change our diets. But most of us do not yet understand that news is to the mind what sugar is to the body. News is easy to digest. The media feeds us small bites of trivial matter, tidbits that don't really concern our lives and don't require thinking. That's why we experience almost no saturation. Unlike reading books and long magazine articles (which require thinking), we can swallow limitless quantities of news flashes, which are bright-coloured candies for the mind. Today, we have reached the same point in relation to information that we faced 20 years ago in regard to food. We are beginning to recognise how toxic news can be.

The velomobile -- a recumbent tricycle with aerodynamic bodywork -- offers a more interesting alternative to the bicycle for longer trips. The bodywork protects the driver (and luggage) from the weather, while the comfortable recumbent seat eases the strain on the body, making it possible to take longer trips without discomfort. Furthermore, a velomobile (even without electric assistance) is much faster than an electric bicycle.

Using nuclear power in place of fossil-fuel energy sources, such as coal, has prevented some 1.8 million air pollution-related deaths globally and could save millions of more lives in coming decades, concludes a study. The researchers also find that nuclear energy prevents emissions of huge quantities of greenhouse gases. These estimates help make the case that policymakers should continue to rely on and expand nuclear power in place of fossil fuels to mitigate climate change, the authors say (Environ. Sci. Technol., DOI: 10.1021/es3051197).

Eighteen months after the nuclear meltdown in Fukushima, children who were not evacuated are found to have thyroid cysts and nodules. What will this mean for their future?

In the immediate aftermath of the nuclear accident, public-health experts worried about the possible risk from radiation. Subsequent analyses have shown that the prompt, if frantic, evacuation of areas around the reactors probably limited the public’s exposure to a relatively safe level (see ‘The evacuation zones’). But uncertainty, isolation and fears about radioactivity’s invisible threat are jeopardizing the mental health of the 210,000 residents who fled from the nuclear disaster.

Researchers and clinicians are trying to assess and mitigate the problems, but it is unclear whether the Japanese government has the will, or the money, to provide the necessary support. Nor is it certain that the evacuees will accept any help, given their distrust of the government and their reluctance to discuss mental problems. This combination, researchers fear, could drive up rates of anxiety, substance abuse and depression.

A very big report came out last month with very little fanfare.

It concluded what we in nuclear science have been saying for decades – radiation doses less than about 10 rem (0.1 Sv) are no big deal. The linear no-threshold dose hypothesis (LNT) does not apply to doses less than 10 rem (0.1 Sv), which is the region encompassing background levels around the world, and is the region of most importance to nuclear energy, most medical procedures and most areas affected by accidents like Fukushima.

A new study has revealed that the rise and fall of leaded gasoline strongly correlates with the pattern of violent crime rates in America.

Past research have linked high lead levels to birth defects, lower intelligence and hearing problems, but now researcher are beginning to uncover evidence that it also causes high levels of aggression.

As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation – which would bombard astronauts on deep space missions to places like Mars – could accelerate the onset of Alzheimer's disease.

The increased rate of childhood obesity in the prefecture since the crisis at the Fukushima No. 1 nuclear power plant has led some observers to speculate radiation fears caused the increase.

1 + 2 = if you use stereo 3D routinely and intensively, you will develop strabismus, period.

What this means is that shutterglasses+LCD TVs, VR helmets, polarized projection with passive glasses, and all autostereoscopic (no glasses) methods like Cubicvue's color filter barrier, parallax barrier, and lenticular arrays, are ALL DANGEROUS TO YOUR HEALTH unless used sparingly.

Yeah, it's just a post on some discussion forum, but it includes a couple of interesting links that, allegedly, back up its claims.
