Hello and welcome to my first Instructable. I will show you how to send emails from any ESP8266 wifi module using Gmail server.This instructable relies on Arduino core for ESP8266 WiFi chip, which makes a self-contained microcontroller from it (no need of AT commands and master devices). You can connect sensors and get notified by email about changes.Before we begin Required hardware: Any ESP8266 (I'm using ESP8266-07 ebay link). In my case USB UART Board(I'm using FT232RL FTDI Serials Adapter Module ebay). Not needed if your board has usb port. Some jumper cables. WIFI router of course.List may be incomplete. Required software: Arduino Software Arduino core for ESP8266 WiFi chip Sketch with project and test code (ESP8266_Gmail_Sender.zip).
Welcome to the dark side of the universe. In a direct contrast with the beautifully bright Milky Way galaxy, a "dark twin" called Dragonfly 44 has been discovered 300 million light-years away in the Coma constellation, according to a new study.
But don’t cue “Star Wars’ ” Imperial March theme music or Darth Vader breathing just yet (even if the closeup image looks like a slightly creepy emoji). Although it’s massive and mysterious, Dragonfly 44 is really just misunderstood.
Dragonfly 44 went unnoticed until last year because, when regarding the darkness of space, this galaxy resembles a virtually indistinguishable blob. But by looking at it with some of the world’s most powerful telescopes, including the Dragonfly telescope array designed and built by study authors Pieter van Dokkum and Roberto Abraham, researchers realized something else. It is named for the telescope that found it.
Dragonfly 44 is an incredibly large but diffuse and dim galaxy. Encircling its core is a halo made up of clusters of stars, much like what we see in the Milky Way. But this galaxy is only 0.1% stars. The Milky Way has more than a hundred times that. The researchers knew that something had to be holding those few stars in place.
“We knew as soon as we discovered the galaxy that it would be so tenuous if it was just made up of stars and no dark matter, that it would quickly disrupt and disappear,” said van Dokkum, lead study author and Yale University astronomer.
A huge amount of gravity was working to hold those stars in place, and once researchers used star velocity to measure how much mass the galaxy contained, they realized that the other 99.9% is dark matter.
To put this in perspective, Dragonfly 44 is comparable in size to the Milky Way, which is 100,000 light-years wide. Mostly it is just unseen because it is cloaked in darkness.
“It’s very exciting because we thought we had sort of figured out what the relationship is between galaxies and dark matter,” van Dokkum said. “This discovery turns that on its head. Now, you can have a hundred times fewer stars in the galaxy with the same amount of dark matter as the Milky Way. That was entirely unexpected, and that means that there is something missing in our description of galaxy formations, and there are physics that we don’t yet understand in that process.”
This newly observed galaxy could hold the secrets to understanding dark matter, the hypothesized ingredient that makes up 90% of the universe. Given the fact that we know next to nothing about it, this find could open the door to our discovery and understanding of the mysterious building block.
Scientists at the Kavli Institute of Nanoscience at the Delft University of Technology (TUDelft) have developed a memory technology that achieves the ultimate physical limit by using individual atoms to represent a single bit of data.
The Hubble Space Telescope has captured an image of the super-dense neutron star at the heart of the famous Crab Nebula, which resulted from one of the earliest supernovae to be recorded by human beings. Its striking form has made it a popular target for amateur and professional astronomers alike.
Solar-concentrating thermal technology is being used to power the air-conditioning system of an entire shopping center in Australia solely from the rays of the sun. It is expected that this technology will help drastically reduce commercial building energy use.
Olivier DUMONT's insight:
Je pense qu’il faut adapter et utiliser ce concept aux centres de données. Avis aux Microsoft, Oracle, AWS, Google, OVH et Cie, investissez dans la recherche de ce concept et dans l’intégration de vos centres de données dans des régions désertiques chaudes… Les océans et mers du monde ne s’en porteront que mieux, leurs eaux ne se réchaufferont pas au prix du refroidissement de vos centres immergés ou pompant une eau froide et régurgitant une eau réchauffée. Parler, Penser Green, c’est bien mais Agir Green c’est mieux ! I think we need to adapt and use this concept for data centers. Notices to Microsoft, Oracle, AWS, Google, OVH and Co. are investing in research of this concept and the integration of your data centers in hot desert areas ... The Oceans and seas of the world will none the worse for it, their waters do not warm up to the cost of cooling your immersed centers, or by the cold water pumping and the heated water regurgitation. Talking, Thinking Green is good but acting is better!
Everything that makes you you is in your DNA, but one hypothesis suggests that you're not just a product of the genetic code, but the mechanical cues that determine how that code folds up in your cells. Now physicists in the Netherlands have confirmed that this second layer of information exists.
The team behind the original Ballbot, which relies on a single ball to get around, is back with an even less complicated system. The upgraded machine uses an experimental induction motor rather than a mechanical drive system for mobility, resulting in a robot with only a single moving part.
The ESP8266 is a wonderful microcontroller. They can be purchased cheaply and have built in wifi. In this guide I will not go over how to flash the ESP8266 module with the basic firmware as this is covered on the http://ESP8266basic.com web site in detail. All the parts to build this project can be found on ebay for less than $10 shipped to the US.
Albert Einstein is famous for his theories on relativity, but what of his other grand hypothesis, the unified field theory that consumed the last 30 years of his life without resolution? So will a unified theory of everything ever be realized?
By trapping photons inside a tiny gold cavity, scientists have created a hybrid state of light and matter. This could allow them to develop tiny on-chip lasers or tweak the chemical bonds of single molecules.
Teleoperated endolumenal bot can navigate inside the body, image and treat conditions without making incisions.
The U.S. Food and Drug Administration (FDA) has just approved the first medical robot from Auris Surgical, a stealthy startup led by the co-founder of industry leader Intuitive Surgical, makers of the widely-used da Vinci robot.
The teleoperated ARES robot (the acronym stands for Auris Robotic Endoscopy System), was cleared by the FDA at the end of May, and could now be used for diagnosing and treating patients.
Auris, which describes itself only as a “technology company based in Silicon Valley,” was previously thought to be working on a robotic microsurgical system designed to remove cataracts, and the company has in fact filed several patent applications along those lines.
However, an investigation by IEEE Spectrum suggests that the company has greater ambitions, including, according to current and former employees, “building the next generation of surgical robots… capable of expanding the applicability of robotics to a broad spectrum of medical procedures.”
A close reading of recent patent applications filed by Auris scientists shows that the company is focusing on so-called endolumenal (or endoluminal) surgery. This involves surgeons introducing flexible robots via the body’s natural openings (the mouth in particular), to address conditions of the throat, lungs and gastrointestinal system. IEEE Spectrum can reveal that Auris has already carried out at least one successful human trial of such a robot, outside the United States.
Because endolumenal surgery does not involve large incisions or (usually) general anesthesia, it benefits fragile patients who cannot withstand the trauma of normal surgery. The Society for American Gastrointestinal and Endoscopic Surgeons estimates that effective endolumenal therapies for obesity and reflux diseases alone could help more than 1 million patients a year in the United States.
Since 1985, the Shell Eco Marathon has pitched teams of students against each other, in an attempt to see who can travel the furthest using the energy from one liter of fuel. It's a simple premise which belies a complex mix of design and engineering challenges.
