LiFi (visible light communication) is the transformation of the light bulb into a wireless communication route that may displace WIFI.
Li-Fi inventor, the German physicist Herald Haas believes that the visible light spectrum can be used to transmit data, as its spectral width is much larger than that of the conventional radio frequencies, and it therefore has the potential to transmit higher bandwidths.
WiFi technology has become very popular, but there are complaints that the wireless signal is unstable, access is slow, and WiFi hotspots are too few while users are ever increasing. Now, there is a new technology that can address these issues. Continue reading
At the International Congress in Moscow, Russia “Global Future 2045″, renowned scientist and futurist Ray Kurzweil spoke about the future of mankind.
With the number of his inventions, Ray Kurzweil can be compared to the famous American physicist Thomas Edison. He has been awarded with praises such as “thinking machine” and “fountain of genius.” He became famous for his prophecies, which tend to come true.
THE WORLD IN YOUR POCKET
In the next century we will move forward at a rate not 100 years, but 20,000 years, promised Professor Kurzweil. The speed of progress constantly increases. Incredible advances that have been made in just a few years, are all around us today: nano-scaling, communications, brain research, deciphering genome.
For example, the critics of early genome project believed that research and deciphering of tens of thousands of base pairs of DNA would take 10,000 years. The project was completed in nearly 10 years. Continue reading
According to a team of philosophers, mathematicians and scientists from Oxford University, who are exploring the future of humanity, there is growing evidence that our reliance on technology can cause elimination of human race.
The media is actively discussing a range of possible disasters that can destroy humanity, but the most “obvious” threats, which include asteroids, earthquakes and volcanic eruptions are unlikely to ruin the world’s population in the near future.
This is the opinion of Nick Bostrom, a philosopher and director of the University of the future of humanity, who, together with his colleagues, is trying to determine the actual causes of destruction for mankind.
In their last publication, the experts are pointing out that people are capable of destroying themselves through their technology. Continue reading
American scientists led by Richard Novatson conducted quite an interesting, but also relevant study which involved 4,000 people (50%-50% of men and women) who were directly connected with the Internet activity, and also spent a lot of time on social networks and other online services.
So, the question was: what would you do if Internet access was forbidden in your country?
The results surprised the scientists. About 67% of people would Continue reading
Scientists of the Duke University in North Carolina claim to have developed a “sixth sense” by using a special implant in the brain of experimental animals.
Lead researcher Miguel Nicolelis said that the results of the experiment led them to important conclusions and paved the way for a new set of prosthetic devices that can be controlled by the brain and may give us an opportunity to understand and “see” the infrared range of the electromagnetic radiation.
Lab mice were induced with infrared sensors, which were adapted to the area of the brain that is responsible for sensing information related to the touch. Therefore, once the animals perceived the infrared radiation, the brain interpreted it as “tactile stimulation”, resulting in the fact that mice did not see the beam, but could feel it, shaking the nose and scratching their fur.

What will our world look like in a hundred years? MIT economist Daron Acemoglu asked that question, when he was waiting for his son’s birth. His most recent work examines the political, social and economic trends of the last hundred years, and then extrapolates them into the future.
Acemoglu drew attention to the grim prospects of growing inequality and environmental pollution, but also sees the positive side, for example, advances in health care. Continue reading
It’s incredible how much each individual’s subconscious may be influenced by the power of suggestion! Since the subconscious mind is what controls our body and whole life, through suggestion we may get a lot of events going – some pleasant, some very unpleasant.
We all have heard of the placebo effect. In an experiment, you are given a drug that you are told is very effective – let’s say, a gastric banding. Of 100 volunteers who tested the drug, approximately 50 finds indeed that they got rid of stomach pain. But, surprise! So-called drug is actually a sugar pearl covered with a blue coating. It contains nothing more than sugar. So, what healed the 50 volunteers? The power of suggestion. They were told that they would do well, and it happened. In fact, their subconscious was convinced of the efficacy of the medicine and gave the necessary commands to the body to feel good.
Far fewer have heard of the nocebo effect. In a similar experiment, you are given a pill about which you are warned that it will harm you – for example, the pill that will provoke stomach cramps. This time, the percentage of people who complained of stomach pain is 90! Obviously, it was the same harmless sugar pill. Thus the power of negative suggestion is Continue reading
Using imaging tools and computer analysis, Japanese scientists could determine the images appearing in the dreams of a group of test subjects with 60% accuracy. So says an article published in the Indian Journal of Science Express.
A group of researchers at the Nara Institute of Science and Technology attempted to find a connection between the visual experiences in dreams and data provided by MRI scans of a human brain at rest.
The level of detail is far from what we see in science fiction films such as “Inception” but experts describe the results as “stunning”, says British newspaper The Daily Mail.
“This is probably the first real live demonstration of brain function as it relates to the content of dreams,” said neurologist and sleep specialist Dr. Robert Stickgold of Harvard Medical School. Although, he said, the creation of a machine that can completely read and record dreams is still far off, the implications of the technology in the more distant future suggests we will one day be able to design a machine that can Continue reading
Scientists say that we may soon be able to control flying drones with our minds, and communicate almost telepathically via smart phones, thanks to temporary electronic tattoos. Todd Coleman, associate professor of bioengineering at the University of California, is developing non-invasive means to control electronics with the mind – a technique that can be used by practically anybody.
Controlling machines by thought alone is no longer strictly the domain of science fiction. In recent years, brain implants have given people the ability to control robots with their thoughts, giving hope that one day we will be able to overcome the disadvantages of serious injury and disability with the help of bionic limbs or mechanical exoskeletons.
But brain implants are an invasive technology, and perhaps should only be used in people who need them for medical reasons. Instead, Coleman and his team are developing flexible wireless chips that read brain activity, which can be placed on the hand in the form of a temporary tattoo. Continue reading
In the science fiction movie Men in Black, agents K and J were able to “clear” the memory of the unfortunate witnesses, thanks to a flash produced by a small portable gadget, to protect the secrecy of alien activity on Earth.
Now, in a paper published in the journal Science, we learn that science fiction is not so far from reality. A team of researchers at the University of Uppsala in Sweden claims to have discovered a technique to erase past memories. The official explanation of the finding is the treatment of phobias and post-traumatic stress.
The results are a significant step forward in memory research. That is, the new findings could improve the intervention methods for millions of patients who suffer from problems such as phobias, panic attacks and post-traumatic stress, says psychologist Thomas Agren. Continue reading
