The graphene and the silver to avoid breaking the Iphone screen
Researchers at the University of Sussex combine graphene and silver and promise to generate crystals for the screens of the mobile iPhone more economically, stronger and more sustainable than any current screen in the market.
What would make these crystals in unbreakable for the most common accidents often have smartphones. At the moment, it is only an experiment, but it is especially promising.
Have discovered that a film coated with small silver nanowires exceeds the performance of the film ITO (what you use in current mobile screens) in terms of conductivity, along with other benefits as low power consumption, low temperature operation and durability, it is readily compatible with existing devices.
However, the silver is also a metal expensive and scarce, so while this is an improvement on the current standards, it is the ideal choice for the future by making the manufacture of these screens. And here is where the graphene.
By combining graphene with silver nanoparticles, researchers at the University of Sussex could create a movie that exceeds in performance to existing technologies, but at a fraction of the cost per screen.
What is interesting is that this type of films of graphene and silver can be incorporated into the current iPhone screens, taking into account that the graphene also increases the conductivity, which means that the devices could be more sensitive to touch and use less energy, be more resistant and cheaper than the current ones. The future looks promising.
The instant messaging company WhatsApp has begun this week to enable an option that allows you to delete the messages you send both in private chats and in groups, although it will do so with limitations.
The new version is available for many but is being implemented gradually and may still don’t have this option in your cell phone.
The service is designed for Windows users, Android and iOS can enjoy. The new option will be called “Delete All” and will delete messages that have been sent to a group as in chat rooms.
All the texts that are deleted will be replaced by a message that says “This message was deleted””.
And it works in the following way: Go to WhatsApp and opens any chat that you want to delete one of the messages.
Then press and hold and holding the message in question.
After you appear the options at the top of your screen to know if you want to delete one or more messages within the same chat.
Press the icon of a dustbin and select “Delete for all”. The messages can be deleted in both talks to two or in group chats.
Although delete messages will not be as easy or may be deleted at any time.As explained in the FAQ section of your web page, the messages can only be deleted if there are several conditions:
– You can only delete messages until 7 minutes after you send them, after this time, the option will be eliminated.
– If the recipient reads it before you delete it, you will not be able to do anything to avoid that you know what you have sent in spite of the fact that delete it within 7 minutes.
Science advances to improve the quality of life of the people; on this occasion is to provide better care to children with the creation of a new portable brain scanner for newborns
A group of French scientists devised a new portable brain scanner for newborns that complies with the same purpose as big machines, according to an article published in the journal Science.
The device, a sort of just 40 grams, combines an ultrasonic probe and video-electroencephalography (EEG), a method that allows you to record the bioelectric activity of the brain.
According to the French scientists, led by Charlie Demene Langevin Institute of Paris, its new portable device allows a direct and non-invasive approach to the brain of newborns.
The scientific method used by the Gauls monitors brain activity with higher resolution than other technologies used at present. A technology that, according to Science, could pave the way for therapeutic innovations for neurological disorders.
Demene and his colleagues have already used the old to detect subtle changes in blood flow in small blood vessels of the brain related to the neural activity in several newborn babies.
The researchers also argue that your device is easy to use and cheap compared with traditional methods.
The research involved scientists from the Laveign, of the National Center for Scientific Research, National Institute of Health and Medical Research and of the Superior School of Industrial Physics and Chemistry of Paris.
Stoptober The application that will help you to stop smoking
This application was created by the Public Health England and offers a plan of four weeks to quit smoking. Was created specifically for the Stoptober campaign, to show your users how much money you are saving with only reduce the amount of cigarettes and thanks to the daily delivery of motivational messages.
One of the most powerful features of this application reminds you, thanks to an image or a motivational message you have chosen at the beginning of the plan, the reason why you want to quit smoking, in addition to being able to share your results in the social networks. On the other hand, one of the disadvantages is that it focuses only on a one-month period.
Would require a great deal of political will to put an end to this habit, but with the invaluable assistance of the technology, we can ensure that the process is more bearable
Stop Smoking -
This app is characterized by a well-designed interface and nice room with a series of phone and a design to the Material Design. On the main screen the progress made from the same day that you stopped smoking, and these data are often used as a mental and emotional support for the final goal is to end definitively with the tobacco cessation.
You have the option to add notes in a journal to be able to return to them at all times and know how were those early days in which you had headaches, or a general sense of fatigue throughout the body.
To extend the life of your mobile device and obtain from him, a better use, with speed, fluidity and one hundred percent operating system, today we explain how to keep your android virus free.
In the world there are billions of these computers connected to the internet and with different versions of the ‘software’, some of them vulnerable to serious attacks. Are the perfect target.
recently discovered a dangerous ‘adware’ for Android almost impossible to remove. These applications are installed on the phones normally by an error or a bad use of the equipment. In theory, if you download apps from Google Play and known developers, you can save many scares. But it is not always sufficient.
Most of these malicious applications are installed on the phones with the intention of access to certain data of interest for criminals. For example, text messages or photos. Juicy data that, in the case of the ‘ransomware’ encrypt all of your data with a password that you don’t have and that you will have to pay a “rescue”.
Another example is the ‘malware’ that is dedicated to using your application of SMS to send messages to premium numbers, but due to changes in legislation in Spain, cases are increasingly smaller. Another type of ‘malware’ very common is the one that tries to download other ‘apps’ to artificially increase the number of downloads. There is also the ‘adware’ programs that are dedicated to show unsolicited advertising.
“The malware on Android comes from our fingers, usually installed without wanting to,” says ‘Teknautas’ Sergio de los Santos, security analyst at the company 11paths. This specialist discusses how a few days ago could find applications in Google Play store for Android, with rear doors that allowed a cyber criminal to have full access to systems and information of the mobile phones.
