A bird weighing only 17 grams that travels 2,770 kilometers across the open sea: the striped warbler
Even taking into account all the fat they accumulate to carry out their impressive migration, striped warblers (Setophaga striata) They have a mass of just 17 grams.
The equivalent of fifty aspirin tablets that makes a stopover of 2,770 kilometers across the open sea.
The journey
The Striated Warbler heads south in the fall from northwestern North America and travels to the Caribbean, and even to Colombia and Venezuela. For a long time, it was unknown how much time he spent flying over the ocean.
Now, however, we already have the data in this regard, as explained David Barrie in his book The most incredible trips:
With the help of extraordinarily small tracking devices, scientists have managed to demonstrate that they can fly endlessly from Long Island to the island of Hispaniola or Puerto Rico, a distance of 2,770 kilometers across the open sea.
So these birds can complete non-stop flights of between 2,270 and 2,770 kilometers in just two or three days. Therefore, before starting the trip, it doubles its body mass by storing lipids and proteins, and it can do so in just one week. Later, The moment it begins to fly, a process of atrophy of its digestive system begins..

In a document sent to the Public Health Commission to be debated and approved this Tuesday in an extraordinary meeting, the Spanish Ministry of Health now proposed to delay the second dose of Pfizer and Moderna prophylaxis.
Although it had been stated that such a delay would not take place, in order to increase the rate of immunizations now it could be postponed this second dose specifically between 6 and 8 weeks among people under 80 years of age. Finally, however, this new strategy will not be adopted.
Other countries that do
This practice, which does not have the approval of the EMA (the data sheet Pfizer does not contemplate a delay in the immunization schedule), however was adopted by Israel and the United Kingdom at the beginning of the year. Although the strategy was viewed with a lot of skepticism at the time, it seems that finally has had good results.
There are already several countries that are following this line. Ireland, for example, has extended Pfizer's second deadline from 21 to 28 days. Denmark, Germany, France and Italy They recommend an interval of 6 weeks for Pfizer and Moderna. Finland has placed all second doses at 12 weeks. The United Kingdom also extended the second doses of all vaccines to 12 weeks, and Canada, to four months.
It should be noted that the EMA does not prohibit extending the administration of the second dose up to 42 days (the product information does not explicitly determine the upper limit between doses), what it suggests, for the moment, is that We are not sure if this new space between vaccines can guarantee the same effectiveness confirmed by clinical trials.

According to what we know today in science, and based on the results of clinical studies in this regard, physically, there is no reason that can explain possible harm from exposure to a mobile phone, a mobile phone antenna, or even , to the 5G WiFi.
If this type of radiation were really harmful through a physical principle unknown to date, there would be an uptick in tumors and cancers because we have been continuously exposed to these radiations everywhere for more than a century. Environmental movements and other related activists, however, They always refer to the same collections of studies (very few and generally with methodological flaws or only carried out on animals).
The 5G conspiracy
Radiation is the phenomenon of transporting energy in a vacuum or a material medium using particles or electromagnetic waves. Depending on how the radiation interacts with the matter that comes into its path, we can distinguish two types: ionizing and non-ionizing.
The first can break the chemical bonds of the living tissue with which it interacts. The second, on the contrary, He doesn't have enough energy to do it..
Most of the radiation around us is non-ionizing, from radio and television signals to visible light. So is radiation from mobile phones, as well as telephone antennas.
Despite this, there are many associations, political groups and even scientists who point out the opposite, violating the most basic principles of physics. There are even organizations that They begin to sabotage 5G telephone antennas because they are convinced that 5G networks act as a kind of catalyst, which amplifies and makes the SARS-CoV-2 pathogen more lethal.
The Stop 5G movement is led by Arthur Firstenberg, one of the main proponents of electrosensitivity and other invented pseudo-diseases related to electromagnetism. One of his star tips is: "turn off the Wi-Fi and your cell phone while you sleep."
nocebo effect
So? Why do some people seem to get sick when they are near cell towers or seem to suffer from electrosensitivity? Simple: because a correlation is not a cause. Just because something happens right after or at the moment we do something does not mean that it is a consequence of it. To find out if there is a cause and not a correlation, studies are done, and the studies have not found anything beyond the correlation.
Probably, in many cases the so-called nocebo effect, just the opposite of the placebo effect. If the placebo effect occurs when a person's body offers a positive response to a drug without any active ingredient (a simple sugar pill), as if it were really a medicine with an active ingredient (for example to reduce vomiting or relieve migraine), the nocebo effect would do just the opposite: the tendency for people to feel bad when they think they have been exposed to something dangerous.
The electrosensitivityTherefore, it would be a chronic manifestation of nocebo coexisting with an anxiety disorder.
This fear seems to arise with greater or lesser virulence every time a new electronic device appears that the average citizen does not understand in depth. In the 1980s, for example, it happened with the use of the microwave oven. Now, it has simply been 5G's turn... until it goes out of style.
In conclusion, there are thousands of elements that interact with our body. We are matter and everything around us interacts with us in some way. For example, visible light, such as that emitted by a light bulb. Microwaves are still light, too, except that they are not visible to the human eye. So if we are afraid of WiFi or microwaves, by that same logic we should be afraid of oxygen or the light of a light bulb. But if we have to be afraid of something, let it be another much more dangerous source of visible light: Sun (either tanning booths), a great generator of mutations in our DNA as soon as we spend too much time exposed to it to tan.
A good example of how social paranoia and erroneous ideas or misinterpretations can lead us to absurd situations is the Seattle Dent Windshield Epidemic, which you can see in the following video, and which shows us that the value of an idea must be measured by a rule. That is to say, with objective experiments, with evidence:
