Computers controlled by thought and other cutting edge developments have been named in a list of the top ten technologies which could shape our future
the complete article is here
The full list of the top ten emerging technologies:
Brain-computer interfaces: It is already possible to type just by monitoring the electrical activity of your brain, but as the technology advances, it could be possible for people with disabilities to operate wheelchairs using only their thoughts.
Mining metals from desalination brine: Large-scale desalination is becoming economically feasible for the first time because of new chemical processes that enable the mining of metals from waste water, or brine.
Nanostructured carbon composites: Cars made from carbon-fibre reinforced composites are as much as 40% lighter than older models, stronger, and more easy to recycle, offering the prospect for huge energy savings.
Grid-scale electricity storage: A fundamental breakthrough is close that would allow the saving of surplus energy from fluctuating renewable sources such as sun and wind within the electricity grid.
Body-adapted wearable electronics: Whether worn on the body, embedded in clothes or even under the skin, these devices can track information, such as heart rate and stress levels, giving people real-time feedback about their health.
Nanowire lithium-ion batteries: New batteries based on silicon – using tiny silicon nanowires – could have a longer life, charge more quickly and hold up to three times the power of existing batteries.
Screenless display: A 3D image projected into space – a “screenless display” – can convey information that a 2D image presented on a screen cannot, and is close to becoming a practical reality.
Human microbiome therapeutics: Drawing on knowledge gained from the Human Microbiome Project in 2012 and other research, human microbiome technology is increasingly seen as an important source of treatment for serious diseases as well as for improving health.
RNA-based therapeutics: RNA, like DNA, plays a part in protein synthesis and, to a lesser extent, the transmission of genetic information. Scientific advances are combining to enable a new generation of targeted, RNA-based drugs that could help find new treatments for cancer and infectious diseases
Quantified self (predictive analytics): RNA, like DNA, plays a part in protein synthesis and, to a lesser extent, the transmission of genetic information. Scientific advances are combining to enable a new generation of targeted, RNA-based drugs that could help find new treatments for cancer and infectious diseases
The idea of progress
Do you consider the invention of smartphones a progress?
You can talk to your friends at any time of the day (or night!), keep in touch with friends and family abroad, read your emails, see your friends’ holiday photos on Facebook, comment on the news on Twitter, download music, play games………….
But how many hours do you actually spend on your phone? Have you ever counted?
Do smartphones bring people closer through modern technology or are they making us more isolated? Technology and smartphones are not bad, but they can take too much time out of our lives. They can be major distractions that hinder our relationships.
Another disadvantage of smartphones is the amount of waste generated: new models are constantly being released, creating a “need” to have the latest model. But what do you do with your old phone? Do you sell it? Exchange it? Recycle it? Put it in a drawer?
Teens are embarrassed to even be associated with the social network as more and more parents attempt to ‘friend’ their children
eenagers are turning their back on Facebook ‘in their droves’ and switching to simpler social networks and messaging apps, new research has found.
Not only are 16-18 year olds moving on to rivals such as Snapchat, Whatsapp and even Twitter, teens are embarrassed to be so much as associated with Facebook, as their parents adopt the network, researchers said.
“Where once parents worried about their children joining Facebook, the children now say it is their family that insists they stay there to post about their lives,” said Daniel Miller, a Professor of Anthropology at University College London, who works on the Global Social Media Impact Study.
“Parents have worked out how to use the site and see it as a way for the family to remain connected. In response, the young are moving on to cooler things.
“What we’ve learned from working with 16-18 year olds in the UK is that Facebook is not just on the slide, it is basically dead and buried.”
Prof Miller, writing on academic news website the Conversation, added that the research found that “slick isn’t always best” as even the teenagers that took part in the study admitted that Facebook is technically better than its rivals.
“It is more integrated, better for photo albums, organising parties and more effective for observing people’s relationships,” he said, yet other factors are much more important to teens – namely the fact they are likely to get a friend request from their mum on Facebook.
“You just can’t be young and free if you know your parents can access your every indiscretion,” he said.
“It is nothing new that young people care about style and status in relation to their peers, and Facebook is simply not cool anymore.”
Instead, rather than using the network to communicate with each other, teens use Facebook as a link to older family and older siblings who have gone to university.
“To prevent overgrazing as others beasts have occupied its terrain, Facebook has to feed off somewhere else. It has thereby evolved into a very different animal,” Prof Miller concluded.
