The first cases in Brazil were nearly 500km from the GM mosquito testing areas, the other side of a state larger than Spain
Brazil wasn't even the first place this particularly explosive microcephaly-linked strain of the Asian lineage of Zika was spotted. Its genetics and behaviour link it to a very similar outbreak in French Polynesia (the ...
The best summary is probably to quote from the WHO director general Margaret Chan's statement on announcing that zika had been declared a "Public Health Emergency of International Concern":
The experts agreed that a causal relationship between Zika infection during pregnancy and microcephaly is strongly suspected, though not yet scientifically proven. All ...

A google search for "All of these men have it" "Stay away from dance halls" mainly got web 2.0 user generated content websites such as reddit and pinterest. I came across a thesis, but it gave a different year, saying that it was 1942.
By contrast, doing a search on the image gave a New Hampshire government website, with the following poster, by Montgomery ...
The claim is false, as evidenced by Prospective Evaluation of the Risk of Serious Bacterial Infection in Children Who Present to the Emergency Department With Hyperpyrexia (Temperature of 106°F or Higher) Pediatrics, July 2006; 118(1): 34–40.
Data were collected prospectively on all children <18 years of age presenting to a pediatric emergency ...
According to research at UC-Davis, quite the opposite is true. The key finding:
Our safety concern was that bacteria such as Escherichia coli O157:H7
and Salmonella, which might contaminate a work surface when raw meat
was being prepared, ought not remain on the surface to contaminate
other foods that might be eaten without further cooking. We soon ...
Tetanus toxin, which has been given the scientific name tetanospasmin, is created when the bacterium Clostridium tetani divides and grows. C. tetani cannot divide in an oxygenated environment, but as a piece of iron flakes off and rusts, it robs the surrounding environment of oxygen. This is the easiest way for C. tetani to reproduce and create toxins (...
The 20 million people in the United States at a given time figure is definitely too low.

Fingerprint scanners use one of two methods
See HowStuffWorks and note that this manufacturer has both "E-Field" and "Active Cap" sensors.
So not all fingerprint readers shine light on your fingers.
Also, patents such as this mention "light" and have no mention of "infra-red" so at first glance it ...
Denise Minger posted a rebuttal at Will Red Meat Kill You? Although she is not a scientist, her article breaks down the arguments against red meat in a very straightforward manner, such that a non-scientist can judge their validity without needing a Ph.D. The points made are:
The quoted study is purely observational, and based on people filling out a survey ...
This myth appears to stem from The Talmud - a vast collection of Jewish laws and traditions.
Although modern-day medicine and science may beg to differ, the sages of the Talmud were under the impression that eating fish and meat together is extremely dangerous to one’s health. In fact, in those days, there was actually a dermatological condition which was ...
As pointed out by @KonradRudolph, this is only a partial answer. It addresses sexually-transmitted diseases, but not others. It needs further additions or a companion answer to properly address the question.
Before we can point to the evidence that covers help, we need some evidence that there is any problem to solve.
In a Salon article, Mary Roach ...
It is fine to have a plausible theoretical model of what might happen when eating more fibre, just so long as the theoretical model matches the actual experimental data. When it doesn't, it is time to rethink the model.
What does the experimental data show? Well, we have a good source here:
Pablo Alonso-Coello, Ed Mills, Diane Heels-Ansdell, Maite López-...
The story is plausible for two reasons:
1) Most enlisted military personnel at a time of war up to the 1950's were young sexually-active males. This has long been the case and applies to the military of many countries, not just the USA.
2) In some cities in Japan, prostitution was legalised and the prostitutes had rates of STD infection of up to 95%.
No, unless you are obese.
According to the National Institute of Health1:
In conclusion, when considering the signaling pathways involved in glucose metabolism in immune cells, it is generally accepted that glucose uptake and metabolism are promoted by PI3-K and its downstream signaling molecule Akt (both in T- and B-lymphocytes). mTOR appears to be more ...
Not only is this not true, but it is explicitly disproved by the sources provided by that very site. LOL!
Sharks do get cancer.

First, it is important to understand the terminology being used.
There is the plant catnip.
From the plant catnip, catnip essential oil can be obtained by steam distillation. Only a tiny fraction of the plant material is essential oil.
According to Catnip as a Source of Essential Oils
Oil yield ranged from 0.1 to 0.2 mL/100 g dry wt
One class of ...
I work in Diabetes research in the UK and Can find no evidence to support the wild claims in the paper, press release and press reports. Sadly hidden away in a table in supplementary data is the fact that the result of improved glucose is a result folrom 3 people who had the vaccine compared to 3 had placebo. This very small number makes it very likely that ...
How much antibiotics affect gut flora is open subject, there are studies showing there is long lasting negative effect. Eg. "Gut microbiota disturbance during antibiotic therapy: a multi-omic approach"
This matters, because gut bacteria does help immune system.

Chronic Lyme disease or also the Post-Lyme disease syndrome is regarded the third and last stage following an infection with Borrelia burgdorferi bacteria , usually acquired through tick bites. No, @Ryathal, it is NOT hard to get Lyme disease, especially not if you're in New England (incidence is over 30 in 100,000 in New England according to the CDC, ...
The idea behind BRAT is that none of the foods included are not particularly harsh on the gastrointestinal system, and are low in fibre. This is mostly true, although intolerances and allergies to Apples are reasonably common. However, there's no particular evidence that this aids recovery. Patients should eat a diet that is gentle on the system and ...
Issue: Whether stopping a course of antibiotics earlier will increase the risk and spread of resistant disease causing bacteria in the body?
Traditional evidence pointed out that early stoppage of antibiotic intake decreases the chances of killing all bacteria causing infection and increases the risk of infection.
By taking the full course ...
These estimates are worldwide, with this being the source (AMR = AntiMicrobial Resistance):
Antimicrobial Resistance: Tackling a crisis for the health and wealth of nations
The 700k number was apparently calculated by extrapolation, which is not very reliable:
The scientists led by Marlieke de Kraker found the Review’s global deaths estimate not ...
So the questions are:
Is the Zika virus "relatively new"?
Zika virus is an emerging mosquito-borne virus that was first identified in Uganda in 1947 in rhesus monkeys through a monitoring network of sylvatic yellow fever. It was subsequently identified in humans in 1952 in Uganda and the United Republic of Tanzania.
To compare, Malaria ...
According to Medline Plus, a common cause of hemorrhoids is straining during the bowel movements. Straining can be due to constipation.

Trials of fiber show a consistent beneficial effect for symptoms and bleeding in the treatment of symptomatic hemorrhoids.
Insoluble fiber absorbs water and makes stools ...
Yes due to community immunity.
Unimmunized persons are protected—indirectly—against some infectious
diseases by being surrounded by immunized persons. This is known as
community (or “herd”) immunity.1
There is a 'community immunity' where the more people have the vaccine, the harder it is for the disease to spread. Conversely, vaccines have a rate ...
Antibiotics are designed to either kill or stop the growth of bacteria by targeting specific traits/functions of the bacteria (bacterial cells are prokaryotes) and not to target eukaryotic cells (human cells), which is rather easy due to the many differences between eukaryotes and prokaryotes. Some antibiotics target the cell wall of a bacteria (eukaryotes ...
In short: There have been no clinical trials.
In December 2016, an article was published in a journal called Alternative and Complementary Therapies. That is normally a red flag, but this one had a surprising conclusion:
Herbal Medicine for Lyme Disease and Other Tick-Borne Infections, Yarnell Eric. Alternative and Complementary Therapies. December 2016, ...
