The study by Orb Media was subject for articles in German news website Spiegel Online (commercial) and WDR (public service broadcasting). Both articles, quoting staff from the German Federal Environmental Agency, agree on criticism of the study:
The study does a "plastic / no plastic" rating, without actually going into how many particles were found.
Summary: The survey this article was based on was biased, poorly designed and poorly implemented. The conclusions cannot be trusted.
This study was examined by Orac who has been "checking in with and covering periodically ever since its inception in 2012, when antivaxers were fundraising for it."
The study has had a history of being retracted:
The 'cactus absorb radiation' meme is very widespread, but seems very short on detailed analysis. So let's start with some basic facts.
None of the articles are explicit about what radiation they are talking about. However the only significant radiation emitted by computer monitors is electromagnetic radiation, which is all around us all the time, and in ...
Toxicity: 30–60 mg (0.5–1.0 mg/kg) can be a lethal dosage for adult humans.
As a rough estimate, a horse can be 400kg, so a lethal does of 200mg-400mg for a horse. Density from wikipedia 1.01 g/cm³.
This means a lethal dose would take up 0.25-0.5 cm³ which is a drop of diameter 0.8-1 cm. This is quite a large drop, approximately 5-10times the dose you ...
Typically No, but it depends on the dose.
The World Health Organisation released a fairly comprehensive report (PDF Warning) called "Fluoride in Drinking-water" that covers this topic.
I apologise for quoting so extensively from this report, but, well, it's excellent. I'd suggest anyone that is skeptical, have a look at the report and the (many) papers it ...
Cockroaches are a potential risk because they act as a vector for a number of diseases, bacteria, and other pathogens:
Cockroaches are arthropod transmitters of disease, acting both as mechanical vectors and as reservoirs of pathogenic agents. It has been shown that cockroaches harbor and transmit, both in nature and under experimental conditions, about ...

According to Wikipedia The transmission power of a GSM handset is limited to a maximum of 2 watts in GSM 850/900 and 1 watt in GSM 1800/1900.
According to a Radio-Electronics.com article "GSM Power Control and Power Class" the base station controls handset power output in the range 2-19 which is 39 dBm to 5 dBm.
Yes, it does, approximately 3 times that amount by weight, but that's not the whole story. You should consider other factors too in determining whether this means it is more harmful:
Firstly, when people smoke cannabis leaves or buds, they smoke them in a rolled cigarette which is usually larger than a tobacco cigarette. This would suggest that not only ...
The symptoms you describe are commonly referred to as electromagnetic hypersensitivity.
I believe the studies you would be interested in are the following:
The majority of provocation trials to date have found that
self-described sufferers of electromagnetic hypersensitivity are
unable to distinguish between exposure to real and fake
The excellent Skeptoid blog has an entry for this very question. It's an entertaining read and well sums up the typical reasoning behind the myth and debunks them. From his conclusion paragraph:

Maybe. There is a lack of significant research into the health benefits standing desks. Most research has been focused on reducing sitting time.
First, it should be understood that the standing desk is not a new invention having been around since the 1800s. Furthermore, in the late 1890s there was a fairly significant push for the use of standing desks, or ...

No. No amount of masturbation ("excessive" or otherwise) causes acne.

The whole idea that prone masturbation is harmful started in 1998 when Dr. Lawrence I. Sank proposed a theory of sexual dysfunction called Traumatic Masturbatory Syndrome (TMS) (1) .
In his journal article, Dr. Sank speculated that the habit of masturbating prone (while lying face down — tending to rub penis against your hand, the surface of the floor, bed,...
It doesn't seem that any cancer victims have yet been identified. The probabilities are low and are assessed over the whole lifetime of people in the worst affected areas.

It is difficult to prove that it is impossible to train dogs to detect hypoglycemia. All that can be done to disprove this claim is to show systematic efforts to train dogs have failed, and that no-one has been able to demonstrate that it is possible.
