When and How to Take Screenshots on Your Phone

When and How to Take Screenshots on Your Phone

Screenshots once may have been a novelty feature on your phone, but the screenshot is now a vital operation that most people use daily. It is convenient, instant, and simple. It allows smartphone users to record, archive, and remember the most important things that come across their screen on a daily basis.

What is a Screenshot?

A screenshot is an image taken of your phone screen in real time. When you take a screenshot, an image file is created of whatever is on your screen at that moment and put into the photo folder. It is an easy way to instantly record what you’re seeing on your screen.

But why are screenshots so important and why do we need them? First of all, screenshots are very easy to take and share. Taking a screenshot is kind of like jotting down a quick note. Maybe you want to remember to research something later. Maybe you want to screenshot something that you saw on social media. There are many ways that smartphone users can take advantage of screenshots.

Share Viral Content With Friends

Often, we see things on social media and the internet that we want to immediately share with our closest friends. Whether it is a funny meme, an important piece of news, or an upcoming event, taking a screenshot is the easiest way to take note of and share content. Unfortunately, sending the link or tagging a friend on social media requires a few steps.

Taking and sending a screenshot is basically two steps. When it comes to sharing with your closest friends, especially those already in your Favorites list, sending the screenshot via text is the quickest way to do this. Most smartphones have basic, easy-to-use screenshot capabilities.

This is something that you should definitely research when shopping for a new phone. Check with your service provider and look for a phone like T-Mobile’s Samsung Galaxy S8 Plus, which has several intuitive ways to take and share screenshots.

Save a Funny or Important Text Conversation

We’ve all been in memorable text conversations. Whether they are hysterical or heartbreaking, they often need to be shared. There are famous Instagram accounts based entirely on screenshots of text conversations. It is much easier to take a screenshot and have the image in your photo folder than it is to scroll through an old text conversation to find the important or funny part.

Many people also take screenshots of social media posts. But, you have to be careful! Snapchat will notify the creator whenever somebody takes a screenshot of a post. This also is something that you might want to consider when posting controversial stuff on any social media platform. Anybody can screenshot your posts and create a permanent record of it. So, even if you post something, regret it, and immediately take it down, it might already be too late.

There are many easy ways to take a screenshot with a smartphone. The most common method is to click the “Volume Down” and “Power” buttons at the same time. This can be done on Apple and Android phones. You do not need to hold them down, just a quick click will do. This is the best method if both hands are on the phone.

You can also take a quick screenshot with the palm swipe method on your Android device. For this, you only need one hand, but you do need to turn on the feature in your settings. To do a palm swipe shot you just hold your hand (fingers extended and palm flat) next to the side of your phone and swipe up or down the entire side of the screen. This works best when your phone is laying on a flat surface.

The scroll grab screenshot is the best way to create images that are bigger than the screen. For instance, you could capture all the important info in a news article that cannot be seen at once on the screen. This is also a feature that you need to enable in your phone settings.

Once you know when and how to take screenshots on your phone it is easy to see why users are increasingly attracted to phones that have intuitive screenshot capabilities.

PipeGuard Robot: Finding Leaks and Fix

PipeGuard Robot: Finding Leaks and Fix

Fixing leaks becomes easier, simpler and swifter with PipeGuard

If you have a problem with your water supply then the best option is to call up a plumber and get it fixed. Just assume if a robot does the same for you then it would like living in a science fiction. One of the world’s most pressing needs is to bring access to the clean and safe water. In order to do so researchers has developed a PipeGuard robot, which can do many things to get rid of the leaks in shortest turnaround time.

It has been found in various studies the modern water distribution system on an average loses as much as 20 per cent of its supply due to leaks. Leaks are dangerous as it causes serious damage to the structures such as building as well as roads. Detecting leaking is another major challenge which happens to be quite expensive and time consuming affair this is where this robot comes in.

PipeGuard Leak detection system developed by MIT

Researchers at MIT has come up with new system which happens to be extremely fast and relatively inexpensive solution which can effectively detect and find even the tiniest of leaks with pinpoint precision. It can work on any kind of pipes regardless of its make and model. This new system is being commonly seen as a ‘PipeGuard’ but researchers has devoted as much as nine years to develop, test and perfect this system under the leadership of a mechanical engineering professor named Kamal Youcef-Toumi. At the upcoming IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in the month of September this team is going to showcase its findings in detail.

How this new system works?

In this new PipeGuard system researcher makes use of a small yet impressive robot made up of rubbery substance which appears to be oversized badminton birdie. This this PipeGuard robotic device is inserted into the water system using the pathway of fire hydrant and it keeps moving as per the flow and continues logging its position throughout the route. It detects leak acts as a PipeGuard through detecting the variation whether small or large made in the pressure at any point of its journey. This data generated through its sensing the pull right at the edges of the rubber skirt and this rubber skirt tends to fill diameter of the pipe which ensures that no space is missed in any case.

Later on this device is collected at another hydrant insertion point and the data collected during its journey is uploaded to the computer for further study. This robotic PipeGuard device doesn’t only rely on the passive movement of the water to travel through the pipe but it also has system in the active version wherein the team can control its motion as per their need. This officially titles as ‘PipeGuard’ and it will be rolled out for commercial usage in such countries which losses huge amount of revenue due to leaks.

Stunning Simulation Shows How The Earth Gets Its Magnetic Field 2,000 Miles Below The Surface

Stunning Simulation Shows How The Earth Gets Its Magnetic Field 2,000 Miles Below The Surface

High-Definition Simulation

A spectacular innovative high-definition simulation has been exposed that tends to look into the stormy core of the Earth, providing new insight on the mechanisms which seems to drive its magnetic field.  Though this field is said to stretch way beyond our planet, as a means of protective barrier against the harmful solar emissions, it originated from deep within at almost 2,000 miles below the surface.

The later supercomputer simulation portrays the flow of liquid metals in the outer core of the Earth wherein the temperature as well as the pressure tends to vary giving rise to electric currents.  With the combination of the rotation of the Earth, it is said to produce a large-scale `dynamo effect’.


According to the French National Centre for Scientific Research, in the case of dynamo effect, the Earth tends to spin along its axis and lines up with the convective motions in the outer core thus resulting in the massive magnetic field which is said to extend spaceward.  Nathanael Schaeffer, lead author had explained that while the procedure is said to be a complex task to be replicated in the lab, usual computer simulations seems to be frequently unreliable thereby compelling the scientists to settle for rough calculations.

 Simulation  Earth Core

Simulation: New Awareness on Outer Core

The researchers from the Institut des Sciences de la Terre and Institut de Physique du Globe de Paris had turned to the OCCIGEN supercomputer in Montpellier, in order to get a proper insight of what really tends to go in the outer core. Schaeffer had stated that their simulation had utilised up to 16,000 interlinked computer processor which had at the same time shared the mass of calculations.

The same took a little less than a year to calculate what otherwise would have taken 250 years by an individual computer. The hard work provided new awareness on the outer core comprising of methods which the scientist suspected were at play though were incapable of spotting in their earlier simulations.

This consists of the westward drift of the magnetic field.  Moreover they also discovered some evidence of the `giant tornadoes’ that had been connected to the strong magnetism towards the poles which had extended downward all through the core.

Build-up of Light Material – Tangent Cylinder

The authors had mentioned in the study, published that towards the interior, the magnetic field was said to be the strongest and associated with a vigorous twisted polar vortex, whose dynamics could occasionally lead to the formation of a reverse polar flux patch towards the surface of the shell.

Besides that, the tough magnetic field also endorsed a build-up of light material in the tangent cylinder which led to steady stratification there for simulation.  The researchers had explained that the new simulation provides a better realistic view of what tends to go on in the outer core of the Earth and hence the magnetic field. This could enable better magnetic field readings as well as forecasts, to support space navigation together with other resolutions.

The simulation, according to Shaeffer  show `zones where the magnetic field is said to be mainly strong as expected already, but more unexpectedly, the simulations show other zones where the field has been nearly insignificant.

Scientists Borrow from Electronics to Build Electric Circuits in Living Cells

Scientists Borrow from Electronics to Build Electric Circuits in Living Cells

Electric Circuits in Living cells: A great mile stone in modern biotechnology

Bioengineers are able to specifically transform the genetic program of cells. In this way they are endowed with new characteristics or abilities that are not so innate but productive. The reprogramming of cells with electric circuits- currently the most dynamic field in synthetic biology – is based mainly on the technological breakthroughs in modern biotechnology.

Genetic methods have been used here for decades to transform microorganisms or cells into living factories for certain natural products, chemicals or pharmaceutical active ingredients. Biotechnologists are here like mechanical engineers, in order to conceive, build and then also continuously check in the cells to tailor-made cells with electric circuits – “production roads”.

While a new biosynthesis pathway is being integrated into a cell in metabolic engineering, some researchers in synthetic biology are pursuing the vision of transforming cells into an intelligent device, which can also be controlled externally through electric circuits. For this purpose, the bioengineers want to develop a catalog with standardized genetic components or switch modules and to assemble them into complex control circuits and electric circuits, which can be specifically controlled.

Their example is electrical engineering, where individual electronic components such as transistors, resistors or capacitors are combined into integrated electric circuits. Such circuits can be standardized and take over so many functions. Intelligent connection of the electric circuits results in complex circuits or even in the construction of living computers.

In fact, bioengineers have a variety of molecular modules at their disposal: genome researchers have already discovered numerous molecular gene switches. With such gene switches – these can be proteins, DNA or RNA molecules – the activity of genes can be precisely controlled.

They can therefore be switched on and off in a controlled manner. Also components of cell communication are always better understood. Optogenetic switches – ie, gene switches that are controlled by light – also offer new scope for controlling the cells in their external behavior.

If such switch modules are linked with other molecular components, then complex control circuits – so-called genetic circuits – can be assembled. The research team of University of Washington are among the pioneers of this approach borrowed from electrical engineering and computer technology. Some notable progress has already been made.

Milestones include a genetic toggle switch, or complex genetic electric circuits that enable cells to process or store binary information like a computer. A catalog with standardized genetic components for bioengineers – the BioBricks – has been developed by UW Researchers.

There are also first application-oriented examples of genetic electric circuits and reprogrammed cells in medicine. Researchers of UW, equip cells with a genetic program that reacts to certain stimuli from the outside and then begins with the production of a substance. This will make the designer cells live measuring station and drugstore in one (to application medicine).

Flexible Pressure Sensors Similar to Suction Cups Mat Based on Octopus Suckers developed

Flexible Pressure Sensors Similar to Suction Cups Mat Based on Octopus Suckers developed

Prototype Krake: New adhesive material with artificial suction cups

Bionic material has best adhered in a moist and oily environment.
With by means of its fine hairs on the feet – called Spatulae – a gecko keeps itself on electrostatic forces even on very smooth surfaces. In a wet environment, however, this adhesion effect fails. As a model for a new, bionic adhesive material similar to suction cups, which also functions in moisture, Korean researchers have now refined the filigree structure of the suction cups of octopuses. As reported in the “Nature” journal, their suction napkins also adhere well to moist skin and are suitable for novel wound dressings.”Mikrometer small structures in our artificial adhesive material increased the suction effect,” Sangyul Baik and his colleagues from Sungkyunkwan University in Suwon explain the basic principle of adhesion. First, the researchers examined the suction cups of the Common Octopus (Octupus vulgaris) and recognized specific bulges in the small cup-shaped troughs. Thanks to this microstructured suction cups, octopuses can cling to slippery rocks under water, or even their beasts of prey.Suction cupsThese microstructured suction cups were copied by the material researchers with a flexible plastic film. They first pressed small troughs with diameters between 15 and 500 micrometers into a thin layer of silicone rubber. They filled the liquid precursor of a polyurethane-acrylate polymer and cured it under ultraviolet light in the micropipes – about 5,000 per square meter. In this case small, dome-shaped bulges were formed in the troughs. If the researchers pressed this bionic film onto a damp surface, it reliably sucked in with adhesive forces of over 40 kilopascals. If silicone oil was used instead of water, the adhesive forces even rose to 180 kilopascals.

Baik and colleagues were responsible for this effect. On the one hand, air was pressed out of the troughs by lightly pressing the suction napkin, and a small vacuum was built up. This adhesion was strengthened by capillary forces, which could be formed thanks to the filigree bulges. The greater adhesion in an oily environment, the researchers explained with the higher viscosity of the liquid compared to water. Even several thousand times detached, the suction napkins retained their adhesion effect.

Suction cups _2

The researchers found the best results with suction cups with a diameter of 50 micrometers. This film adhered reliably even on damp skin. As a first application, Baik proposes new types of patches to cover inflammatory and wetting wounds. But the thin silicon wafers for the production of computer chips could also be lifted out of the reaction baths with this suction napkin. “This approach could be used to move robots, biomedicine or toys,” says Jonathan Wilker from Purdue University in West Lafayette, assessing the Korean results in an accompanying commentary.
