Good news for a change!

It’s a big wide Universe out there…
We have already seen kits to convert traditional bicycles into electric bicycles and to convert them into pedal-powered snow machines: this electric snow bike kit goes a step further by combining the two.
Manufactured by the Canadian electric mobility company Envo, eThe kit is designed for use with mountain bikes.
Shipping Kit
According to Envo, the kit offers a motor-assisted top speed of 18 km/h and is efficient for a range of approximately 10 km, or two hours of use, for 8 hours of charging.
It should be noted that the bike's chain length needs to be adjusted and its rear derailleur needs to be removed, so installation is not simple.
The bike's existing chain delivers power from the rider's legs to a sprocket attached to the side of the motor, while a 48V/17.5Ah lithium-ion battery pack mounted on the down tube provides electrical energy.
A crank-mounted sensor detects when the rider is pedaling, signaling the motor to activate accordingly. If the rider wishes, they can also activate the motor without pedaling, using a handlebar-mounted thumb throttle switch.
For relatively compact snow, users may prefer to keep the existing front wheel in place. However, for deeper snow, an included adapter allows you to replace that wheel with a snowboard.
In this way, the bicycle can easily cover any terrain, which opens a little more ground towards universal transportation. The electric bicycle is probably the next evolutionary step to the bicycle, which in its day already constituted a change in the mobility of society; it even worked like a kind of Tinder to meet future partners further away from your area and freed the women, as you can see in the following video:

We really don’t need this.
There are already many people who have put up the Christmas tree, the colored lights also shine in the streets... however, Some complain that Christmas seems to come earlier and earlier.
The good news for those who enter "Christmas mode" so prematurely is that they seem more sociable and are happier, too. The pandemic, in fact, has brought forward the decorations.
Christmas in pandemic
Today's Christmas can appear in our stores from November 1, since Christmas items replace Halloween products. At this point, we're used to the ever-expanding holiday season, but that's usually only seen in retail spaces eager to make the most of seasonal spending.
However, this year it has also reached many homes earlier, with news of decorations that were already placed on Halloween.
The festive tone has become a way to add joy and warmth to the gloom of pandemic restrictions. Christmas decorations bring back happy memories, and psychologists already suggested in a study than those who put up their decorations early They are happier than their peers and seem more sociable.
Because, according to the study, those who put exterior decoration in their homes can use the exterior of their home to communicate attachment and possibly to integrate into the social activities of a neighborhood.
Without a doubt, here we can find echoes of testimonies of soldiers in the trenches during the First World War, which viewed Christmas rituals on the Western Front as a connection to normality.

It is not a fragment of Frankenstein's monster, of Mary Shelley: Inanimate matter can be animated with a simple spray. The spray contains particles of iron, polyvinyl alcohol and gluten, which combine with water to form sticky magnetic skins or 'M-skins'.
Thanks to the magnetic properties of the aerosol, ordinary objects such as origami paper and cotton thread have been brought to life, according to A study published in Science Robotics.
Millirobots
The researchers captured images of the 'millirobots' rolling, swimming and walking, but they also performed tasks with a more relevant purpose: simulated biomedical procedures. Robotic catheters navigated narrow blood vessels and egg-shaped capsules delivered medications to the stomachs of live rabbits.
This is the magic of this spray, which proposes a minimalist approach to building milirobots by coating inanimate objects with a magnetic bonding compound spray. As seen in the video, the real object of this experiment is to create milirobots capable of entering the arteries or the stomach, and removing blockages thanks to movement, or releasing medications:
This approach allows covering a variety of one-dimensional objects with a thin enough film such as to preserve the original size, morphology and structure of objects while providing a performance of up to hundreds of times its own weight. Under the activation of a magnetic field, milirobots can demonstrate a variety of locomotor skills.
In addition, the magnetic film of the milirobots can be reprogrammed and disintegrated at any time. The liquid begins to disintegrate after about eight minutes in a strongly acidic environment (pH 1), but its durability lasts up to about 15 minutes if an additional layer of PVA is added. while if the iron particles are replaced with nickel particles it could remain stable for even more than half an hour..

Charles Percy Snow, in his famous conference On “The Two Cultures”, he expressed it forcefully: «What do you understand by mass, or by acceleration? It is the scientific equivalent of Can you read?
That we see in the media intellectuals who are as scientifically trained as they are in everything else may be, for the moment, an entelechy: the minimum we should demand is that intellectuals who embrace pseudoscience be portrayed as anti-intellectuals. Because they don't base their opinions on evidence, basically..
Politically accepted nonsense
It is not about censoring ideas, or even avoiding exploring heterodox scientific ideas. The point is to consider deeply anti-scientific statements as uneducated, as the physicist emphasizes. Alan Sokal in his book Beyond intellectual frauds:
It would be better to imagine a continuum where well-established science (for example, the idea that matter is made up of atoms) is at one end; Next would be cutting-edge science (neutrino oscillations, for example) and dominant but speculative science (string theory); then, much further, bad quality science (N rays, cold fusion), and at the end, after a long journey, pseudoscience.
If you defend pseudosciences such as homeopathy, if you attack vaccines, if you suggest that 5G causes harm and a long list of ideas widely disseminated in the media, you should automatically be classified as an unread, uninformed, uneducated person, or perhaps even fanatical about some sectarian movement.
Again, it must be emphasized that these ideas can be expressed with the same joy as Miguel Bose publish your nonsense about the coronavirus on their networks. There is no need to censor. What we have to do is conveniently label, criticize, and, above all, question the media that encourages such characters and the institutions that elevate them to the category of intellectual, wise, or even political.
Yes because Among politicians we can find a certain percentage of functional illiterates. (that is, magufos) who have even directed ministries linked to science, such as Health. In the following video you can see some of the most scandalous cases. Cases that, perhaps when we consider science as an indistinguishable part of general culture, will not take place again:
