Travelling through time, invisibility cloaks and teleporting could all happen within today's children's lifetimes, experts have predicted
Children could be travelling between centuries as soon as the year 2100, while teleportation could become a regular occurence by around 2080, professors from Imperial College London and the University of Glasgow have said.
"The good thing about teleportation is that there is no fundamental law telling us that it cannot be done and with technical advances I would estimate teleportation that we see in the films will be with us by 2080,” said Dr. Mary Jacquiline Romero from the School of Physics and Astronomy, University of Glasgow.
“Teleporting a person, atom by atom, will be very difficult and is of course a physicist's way, but perhaps developments in chemistry or molecular biology will allow us to do it more quickly. The good thing about teleportation is that there is no fundamental law telling us that it cannot be done and with technical advances I would estimate teleportation that we see in the films will be with us by 2080,” she said.
“Time travel to the future has already been achieved, but only in tiny amounts. The record is 0.02 seconds set by cosmonaut Sergei Krikalev. Whilst that doesn't sound too impressive, it does show that time travel to the future is possible and that the amount of time travel couldn't be far greater," he argued. “If you travelled through space on a big loop at 10 per cent the speed of light for what seemed to you like six months, approximately six months and one day would have passed on Earth. You'd have time travelled a day into the future. Travel at the same speed for 10 years and you'll time travel nearly three weeks into the future. I would say we are looking at 2100 as a very optimistic timescale for travelling weeks into the future.”
Invisibility cloaks, as featured in Harry Potter, could be "entirely feasible" within the next 10 to 20 years, Professor Chris Phillips, Professor of Experimental Solid State Physics at Imperial College London said.
Harry tests his invisibility cloak for the first time
“One way to create an ‘invisibility cloak’ is to use adaptive camouflage, which involves taking a film of the background of an object or person and projecting it onto the front to give the illusion of vanishing, " he added.
"We’re actually not that far away from this becoming a reality – rudimentary technology versions of this have already been created – but the main problem is that the fibre-like structures in the adaptive camouflage need to be so tightly woven that it’s incredibly labour intensive. With developments such as 3D printing allowing us to create previously impossible materials, it’s entirely feasible that we could see a ‘Harry Potter’-like invisibility cloak within the next 10 to 20 years.”
The research was conducted by the Big Bang UK Young Scientists and Engineers Fair, which compared the predictions of scientists to that of a panel of 11-16 year-olds.
While their speculation was largely in line with the experts' expectations, the children thought time travel could be feasible by 2078. They also dramatically overestimated when they might be able to become space tourists - anticipating it might take another 30 years, when commercial space flights are due to launch in 2015.

A technique for high throughput screening of substances that could cause DNA damage has been developed by scientists. The technology allows for testing of drugs and cosmetics that could pose a risk to human health, and assesses damage done to DNA, while reducing reliance on animal testing, researchers say.As more hand held and portable devices on the market are being developed for nanoparticle-based DNA sensing, many are able to detect and analyze organisms one-thousandth of the widt [...]
by PL Chang and JacquelineMany scientists are challenging the idea that we humans have more than two or even three strands of DNA. Some even believe that we may have a total of 12 strands or more. DNA is the acronym used for deoxyribonucleic acid. It contains the codes that act like a blueprint, giving instructions to cells and telling them how to behave. MostDNA is found in the cell nucleus (nuclear DNA), while a small amount is found in the mitochondria (mDNA).The conventional DNA m [...]

| This image shows water through time in the formation of the solar system, as scientists have revealed that water filling the Earth's oceans pre-date the formation of the sun |

"Our findings show that a significant fraction of our Solar System’s water, the most-fundamental ingredient to fostering life, is older than the Sun," said Conel Alexander.
WASHINGTON, Sept. 25 (UPI) -- If you took a dip at the beach this summer, chances are you bumped up against some truly ancient water molecules -- water older than the sun. In fact, there's probably interstellar water hanging out inside all of us -- we are 60 percent water, after all.
A new study suggests as much as a third of Earth's ocean water was likely formed prior to the birth of the sun and sourced from deep space ice.
Like all planets in our solar system, most of the Earth and much of its water was formed from the debris floating around our young sun -- a hot cloud of gas and other cosmic material known as the solar nebula. Included in this nebula were ices, but we know there are also ices floating in interstellar space -- as evidenced by meteorite samples.
What scientists haven't been sure of, however, is exactly how much of our water is made of interstellar ice, and how much was formed locally in the solar nebula. To solve that quandary, a team of scientists led by L. Ilsedore Cleeves from the University of Michigan built a model to predict the answer. The model was based on the scientists' understanding of the chemical circumstances that enable the formation of "heavy" water molecules -- a molecule with a deuterium atom instead of a hydrogen atom.
About 1 in every 3,000 water molecules has a deuterium atom. The scientists' model, part chemistry part mathematics, showed that the solar nebula wasn't capable of forming all of Earth's heavy water on its own, and thus suggested roughly a third of Earth's water is really alien water.
"Our findings show that a significant fraction of our Solar System's water, the most-fundamental ingredient to fostering life, is older than the Sun, which indicates that abundant, organic-rich interstellar ices should probably be found in all young planetary systems," said Conel Alexander, a researcher at Carnegie Science institute in Washington.
As Alexander explained, the revelation suggests the materials necessary for life are probably not as rare as scientists previously thought.
"If water in the early Solar System was primarily inherited as ice from interstellar space, then it is likely that similar ices, along with the prebiotic organic matter that they contain, are abundant in most or all protoplanetary disks around forming stars," Alexander added.
The study was published this week in the journal Science.
