Get access to any computer via Google’s Chrome Remote Desktop service

Get access to any computer via Google’s Chrome Remote Desktop service

With Google’s free Chrome Remote Desktop service, you can get access to any computer that runs on Windows, Linux, Mac or Chrome OS. You can access any computer from any mobile device or any other desktop.

Earlier, if one had to access a computer remotely, then it would be a costly affair. It involved a complicated and costly software and technical know-how. Now, it is become so easy that you can even get access to any of the remote device’s contents and click on it just as if you were actually in front of the computer.

How to Use Chrome Remote Desktop

The greatest advantage is that Chrome Remote Desktop allows you to sign into your own personal computer or work computer from afar.

In order to access the  Remote Desktop service, you need to decide on the type of connection, follow a few easy steps and you will be remotely connected.

Steps you need to follow when accessing your own computer using the  Remote Desktop

Firstly open Chrome on the host computer. Navigate to Google’s Chrome Remote Desktop web app. Next click on the circular blue arrow icon within the box labelled ‘Set up remote access.’ After being prompted to download the Chrome Remote Desktop extension, you need to click the ‘Add to Chrome’ button and confirm your desire to proceed. On returning to the original tab, there will be a prompt to enter your computer’s name and move ahead. Click the ‘Next’ button, create a PIN composing six digits. To access the computer remotely, the PIN is needed along with being signed into your Google account for security purposes. A warning may show up in order to ensure that you want to allow the app access to start a remote connection.

How to Prepare Computers for Remote Connection:

You will gain access anytime the computer is powered on and Chrome is running. In case you require the connections to remain for a long time, then go to the computer’s power management settings to ensure it does not go into hibernation mode.

To disable the remote connections, click the Chrome Remote Desktop icon which is on the right of the browser’s address bar. Then click the trash can icon that is alongside the computer’s name to remove it from the app. You can also uninstall the app by right clicking its icon and choosing ‘Remove from Chrome.’

The next step is to connect the computer from either another desktop or mobile device. For this, you need to go to the Chrome Remote Desktop website – remotedesktop.google.com/access which is within the Chrome browser. Sign into Chrome by using the same Google account that you used on the host computer. Your computer’s name will appear and by clicking on it you can begin the connection. You will be in and you can do anything you want, just as if you were sitting in front of the computer.

For access via mobile, download the Chrome Remote Desktop app for iOS or Android devices. If you are signed into the same Google account, the app will show the computer and allow you to connect with a tap and typing your PIN.

Google Stadia: A Platform for Gaming Enthusiasts

Google Stadia: A Platform for Gaming Enthusiasts

What is Google Stadia?

Google Stadia, the future of gaming is a platform for the gaming enthusiasts. It is not a box, but according to Google it could be a virtual stadium. It is in effect a game console running in cloud, built for the YouTube generation. The  Stadia is the future for games to be played anywhere. The best part is that one will not require a game console or either an expensive gaming PC.

With  Stadia, one essentially requires access to Google Chrome’s browser in order to play games on one’s phone, tablet, PC or TV. Google Stadia is a cloud streaming service and the future of gaming.

Google Stadia cloud streaming services

YouTube and Chrome will be the main Google Stadia cloud streaming services. Google is relying on YouTube which is popular with gaming clips and also the creators who stream games to people on services like Twitch. It is on these platforms, where kids love to spend time to chat, play or even watch streamers.

YouTube will help push Google Stadia in a big way. With Stadia, when you watch a clip, you can instantly play it. The streamers will create lobbies whereby the fans can join and play along with them on YouTube with Stadia supporting instant clipping to the video service.

Google Stadia will be available through the Chrome browser, Chromecast and initially only on the Android devices.

Stadia games and operating system

Google unveiled Stadia games and Entertainment studio for creating exclusive Stadia titles. Not much is known with regards to the details on what games they will be creating.

If Google is planning to dominate the gaming field, then they need to get games on its platform.

Linux will be the operating system that will power its hardware on the server. In other words, the developers will have to port their games to Stadia. The big challenge for Google is to convince big publishers to join their bandwagon. There is not much details with regard to the cost for developing, publishing and running games on  Stadia.

Information regarding Google Stadia

The cost of the this service for the consumers is still not known. As regards the launch, it is slated to be in 2019. Important information regarding the  Google Stadia like ‘Can the consumer own their own games?’ or ‘Will it be based on subscription?’ has still not been answered by Google.

As for the games streaming, Google will use its own technology to stream games in 1080p or 4K to devices. Latency will be reduced with the game client and server being on the same machine. All this definitely requires an internet connection to access Stadia which should be approximately 25 Mbps for 1080p resolution at 60fps.

There will be no scope for gaming offline, since Stadia service is completely cloud based. The image quality will be based on your internet connectivity.

Google has hired a lot of talented people in the industry to make Google Stadia the future in gaming.

Technique Identifies New Electricity Producing Bacteria

Technique Identifies New Electricity Producing Bacteria

When you live in bad conditions you learn to adapt. This is a rule that is common to all living beings and is therefore also applicable to some bacteria. There are certain species of bacteria that live in oxygen deprived areas and in such situations they have to find a way to breathe that does not involve oxygen. These bacteria are found in places deep within mines, at the bottom of lakes and sometimes even in our guts, all these places don’t have much oxygen and they need to adapt. How do they do this you say? These bacteria are able to breathe by taking in and pumping out electrons rather than oxygen. This means these bacteria are also electricity producing bacteria.

The difficulties in Cultivating Electricity Producing Bacteria:

These electricity producing bacteria can be used to run fuel cells, purify sewage water besides a host of other uses. But getting this type of bacteria has been a problem.

Scientists are unable to produce these electricity producing bacteria in laboratories because of the extremely tiny size which is even smaller than a mammal’s cell.

Engineers at MIT have overcome this problem by engineering a way by which they can get small samples of bacteria. They have come up with a microfluidic technique that allows them to produce samples of electricity producing bacteria. This ability to generate electricity is known as polarizability, this microfluidic technique allows scientists to harness electricity from bacteria in a much safer and more efficient manner than what you have today.

This technique also gives the ability to distinguish from different types electricity producing bacteria. Scientists believe that there is a broad range of such kind of bacteria and that electricity producing capabilities are not restricted to a certain kind of bacteria.

How do the Bacteria generate Electricity?

Electricity producing bacteria generate electrons in their cells which then transfers it across their cell membranes via channels made of surface proteins. This process of transfer is known as extracellular electron transfer or EET for short.

Existing Techniques for Acquiring Electricity Producing Bacteria:

Existing techniques for growing electricity producing bacteria involves growing a large batch of such bacteria and measuring the EET activity. This is a time consuming and meticulous process. Still other techniques exist that involve rupturing the cell to probe the protein activity within it.

Using the Microfluidic technique:

Researchers used a microfluidic setup to compare various electricity producing bacteria each possessing a different type of electricity. Such strains include a strain of bacteria that actively produces electricity in microbial fuel cells, also known as “wild- type” bacteria.

Researchers wanted to see whether there is a relation between a bacteria’s electricity producing abilities and its behavior in a microfluidic device conducted under a dielectrophoretic force.

Scientists used the microfluidic device and passed the electricity producing bacteria through it by passing a voltage through the device. When the electricity producing bacteria reached the narrowest part of the device, another stronger voltage was passed through the other side of the device thus trapping the bacteria. Some bacteria got trapped at a higher voltage while others got trapped in a lower voltage setting. This suggests that each type of electricity bacteria reacts differently.

Team Invents Method to Shrink Objects to the Nanoscale

Team Invents Method to Shrink Objects to the Nanoscale

The scientists from MIT have discovered a novel way of creating 3-D nanoscale objects. They shrink objects to the nanoscale by making a larger structure with a laser and then shrinking it. It produces 3-D structures that are one thousandth the size of the original.

They are able to shrink objects to the nanoscale of almost any shape. The objects can be patterned with useful materials, including metals, quantum dots and DNA.

MIT Scientists have discovered a novel way to Shrink Objects to the Nanoscale

According to Edward Boyden, the Y. Eva Tan Professor in Neurotechnology and an associate professor of biological engineering and of brain and cognitive sciences at MIT, you can put any kind of material into a 3-D pattern with nanoscale precision.

This is a technique called Implosion Fabricaton, whereby the researchers pattern a polymer with a laser and create any shape and structure. Useful materials are then added to the polymer and later on it is shrunk to give a structure that is one thousandth the size of the original.

Earlier, there were ways of shrink objects to the nanoscale, but they have generally been very slow and ineffective. Layer upon layer needed to be added upon the 2-D nanostructures or just have pyramid like structures. There is a method to directly print 3-D nanoscale objects, but that is only with materials like polymers and plastics, which is not suitable for many applications. But that is not enough for complex structures like linked chains or hollow structures. To shrink objects to the nanoscale and for nanofabrication to reach its potential, it should also be able to work with complicated shapes.

The procedure to shrink objects to the nanoscale

Boyden and his students used a technique known as expansion microscopy. This was used for high-resolution imaging of brain tissue. The brain tissue was embedded into a hydrogel and then expanding it in order to allow high resolution imaging of the brain tissue with a regular microscope.

When the process was reversed, then the scientists were able to create large objects embedded in expanded hydrogels and then shrink objects to the nanoscale. This was known as implosion fabrication.

They used a very absorbent material made of polyacrylate, found in diapers for the nanofabrication process. The polyacrylate was soaked in a solution containing fluorescein molecules, an orange dye with yellow-green fluorescence used as a scientific marker. They act as anchors that can bind to other types of molecules.

You can attach light to any part of the anchors and also anything else like a quantum dot, DNA or a gold nanoparticle. With the fluorescein in place, an acid is added to prevent negative charges in the polyacrylate gel. They no longer repel each other thereby causing the gel to contract. There is ten times shrinkage in each dimension which equals a thousand fold reduction in volume. In this way they could shrink objects to the nanoscale.

Though there have been attempts to invent better equipment to make nanomaterials, Samuel Rodriques, a lead author and grad student says that just using the existing systems and embedding it in this gel, you can shrink objects to the nanoscale.

When you shrink objects to the nanoscale, then there is great potential for widespread applications. Specialized lenses that are shrunk can be used to study fundamental properties of light. They could be used for cellphone cameras and microscopes. The process to shrink objects to the nanoscale could be useful in the future for creating nanorobots.
