The Video Assistant Referees (VAR) was made official by the FIFA for the World Cup in Russia in order to end the refereeing controversies. this system is considered a total justice for football, VAR and the anti-dopping system have an Achilles’heel: The mind control with brain nanobots. Mind control is a reductive process in which a man is reduced to an animal, machine or slave. Nowadays, the mind control could be developed with invasive neurotechnology as brain nanobots that can control directly the activity of victim neurons stimulating or inhibiting them and thus, control different body’s functions like the motor functions. It could be used by nanomafias in sports like soccer and could being applied on football players of the teams that are participating, nowadays, in the current world cup. The FIFA should be prepared to avoid the mental control and the illicit use of brain nanobots, as they are regarding drugs using the anti-dopping in order to get the justice in world football.
Keywords: nanotechnology, brain, internet, interface brain-machine, crime, soccer.
The 2018 FIFA World Cup is the 21st FIFA World Cup, a quadrennial international football that is organized by FIFA. It is currently ongoing in Russia starting from 14 June and will end with the final match on 15 July 2018. The Video Assistant Referees (VAR) was made official by the FIFA for the World Cup in Russia in order to end the refereeing controversies. The FIFA implemented the VAR that is a live support system for referees, which gives them the option of changing decisions that could influence in the scoreboard or in the match incidences although this system is considered the final point for the controversies in refereeing decisions and represent for FIFA and most analysts, a total justice for football.1 The VAR and the anti-dopping system have an Achilles’ heel.
Zhiling Guo, a Research Fellow at the University of Birmingham outlines research into how nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape. A new study reveals that this may create potential neurological impacts that could be both positive and negative.

Metal-enhanced photoluminescence is able to provide a robust signal even from a single emitter and is promising in applications in biosensors and optoelectronic devices. However, its realization with semiconductor nanocrystals (e.g., quantum dots, QDs) is not always straightforward due to the hidden and not fully described interactions between plasmonic nanoparticles and an emitter. Here, we demonstrate nonclassical enhancement (i.e., not a conventional electromagnetic mechanism) of the QD photoluminescence at nonplasmonic conditions and correlate it with the charge exchange processes in the system, particularly with high efficiency of the hot-hole generation in gold nanoparticles and the possibility of their transfer to QDs.
Inspired by the flexible joints of humans, the scientists from the University of Science and Technology of China (USTC), of the Chinese Academy of Science, led by Prof. Wu Dong, proposed a two-in-one multi-material laser writing strategy that creates the joints from temperature-sensitive hydrogels as well as metal nanoparticles.
Poor battery life is the favorite complaint when it involves smartphones and laptops. As a wireless society, having to tether ourselves right down to power up our gadgets seems more and more a nuisance. And while researchers are looking into wireless charging, if batteries were better we might worry less.
Now, a brand new technology promises just that. Researchers from the University of California, Irvine, have invented a nanowire-based battery that may be recharged many thousands of times, a big leap towards a battery that doesn’t require replacing.
Flat screen TVs that incorporate quantum dots are now commercially available, but it has been more difficult to create arrays of their elongated cousins, quantum rods, for commercial devices. Quantum rods can control both the polarization and color of light, to generate 3D images for virtual reality devices.
Using scaffolds made of folded DNA, MIT engineers have come up with a new way to precisely assemble arrays of quantum rods. By depositing quantum rods onto a DNA scaffold in a highly controlled way, the researchers can regulate their orientation, which is a key factor in determining the polarization of light emitted by the array. This makes it easier to add depth and dimensionality to a virtual scene.
“One of the challenges with quantum rods is: How do you align them all at the nanoscale so they’re all pointing in the same direction?” says Mark Bathe, an MIT professor of biological engineering and the senior author of the new study. “When they’re all pointing in the same direction on a 2D surface, then they all have the same properties of how they interact with light and control its polarization.”
The innovation – which has undergone advanced pre-clinical trials – is effective against a broad range of drug-resistant bacterial cells, including ‘golden staph’, which are commonly referred to as superbugs.
Antibiotic resistance is a major global health threat, causing about 700,000 deaths annually, a figure which could rise to 10 million deaths a year by 2050 without the development of new antibacterial therapies.
The new study led by RMIT University and the University of South Australia (UniSA) tested black phosphorus-based nanotechnology as an advanced infection treatment and wound healing therapeutic.
Results published in Advanced Therapeutics show it effectively treated infections,… More.
Scientists at the Indian Institute of Science (IISc) have developed a new approach to potentially detect and kill cancer cells, especially those that form a solid tumor mass. They have created hybrid nanoparticles made of gold and copper sulfide that can kill cancer cells using heat and enable their detection using sound waves, according to a study published in ACS Applied Nano Materials.
Early detection and treatment are key in the battle against cancer. Copper sulfide nanoparticles have previously received attention for their application in cancer diagnosis, while gold nanoparticles, which can be chemically modified to target cancer cells, have shown anticancer effects. In the current study, the IISc team decided to combine these two into hybrid nanoparticles.
“These particles have photothermal, oxidative stress, and photoacoustic properties,” says Jaya Prakash, Assistant Professor at the Department of Instrumentation and Applied Physics (IAP), IISc, and one of the corresponding authors of the paper. Ph.D. students Madhavi Tripathi and Swathi Padmanabhan are co-first authors.
We could soon see more lithium-ion batteries made with recycled materials thanks to a new partnership. BASF, a battery materials producer, has announced that it’s teaming up with Nanotech Energy, a maker of graphene-based energy products, to produce lithium-ion batteries with recycled materials for customers in North America.
While BASF will create the cathode active materials using recycled metals from a Battle Creek, Michigan facility, Nanotech will use those materials to create the lithium-ion battery cells. Making the batteries with recycled metals could decrease their CO2 footprint by around 25 percent, according to BASF.
Additionally, BASF and Nanotech Energy will also work with the American Battery Technology Company (ABTC) and the Canada-based TODA Advanced Materials Inc. ABTC will recycle the materials gathered by Nanotech, such as nickel, cobalt, manganese, and lithium. TODA will then use the materials to create battery precursors, which BASF will then convert into cathode active materials.
