New York, Feb 18 (IANS) If you thought wireless charging in smartphones was a new thing, you are mistaken as researchers have found a new method to power devices without connecting them to cords.
The new method developed by Disney Research, published in the journal PLOS ONE, for wirelessly transmitting power throughout a room enables users to charge electronic devices as seamlessly as they now connect to WiFi hotspots.
The researchers demonstrated their method, called quasistatic cavity resonance (QSCR), inside a specially built 16-by-16-foot room at their lab.
They safely generated near-field standing magnetic waves that filled the interior of the room, making it possible to power several cellphones, fans and lights simultaneously.
"This new innovative method will make it possible for electrical power to become as ubiquitous as WiFi," said Alanson Sample, associate lab director and principal research scientist at Disney Research.
"This in turn could enable new applications for robots and other small mobile devices by eliminating the need to replace batteries and wires for charging," added Sample.
According to Sample, wireless power transmission is a long-standing technological dream.
"In this work, we've demonstrated room-scale wireless power, but there's no reason we couldn't scale this down to the size of a toy chest or up to the size of a warehouse," Sample noted.
The QSCR method involves inducing electrical currents in the metalised walls, floor and ceiling of a room, which in turn generate uniform magnetic fields that permeate the room's interior.
This enables power to be transmitted efficiently to receiving coils that operate at the same resonant frequency as the magnetic fields.
The induced currents in the structure are channelled through discrete capacitors, which isolate potentially harmful electrical fields.
"Our simulations show we can transmit 1.9 kilowatts of power while meeting federal safety guidelines," Chabalko said, adding that this was equivalent to simultaneously charging 320 smart phones.

London, Feb 18 (IANS) In a first, researchers have developed a novel DNA computer that is capable of detecting several antibodies in the blood, that may allow better control of the medication for diseases like rheumatism and Crohn's.
"What is special about this system is that it can think and that it can be connected to actuation such as drug delivery," said Maarten Merkx, professor at Eindhoven University of Technology (TU/e) in The Netherlands.
To determine whether someone has a particular disease, it is essential to measure the concentration of specific antibodies -- the agents that our immune system produces when we are ill.
The new method will translate the presence of each antibody into a unique piece of DNA whereby the DNA computer can decide on the basis of the presence of one or more antibodies whether drug delivery, for example, is necessary.
"The presence of a particular DNA molecule sets in motion a series of reactions whereby we can get the DNA computer to run various programs," explained Wouter Engelen, doctoral student at the Eindhoven University of Technology.
"Our results show that we can use the DNA computer to control the activity of enzymes, but we think it should also be possible to control the activity of a therapeutic antibody," Engelen added.
In addition, the system can measure the quantity of therapeutic antibodies in the blood and decide whether it is necessary to administer any extra medication used in treating chronic diseases like rheumatism or Crohn's disease.

Moscow, Feb 18 (IANS) Raising hope for an anti-ageing drug in just two to three years, a group of Russian and Swedish scientists have managed to slow down ageing of mice with the use of a novel compound.
Development of typical traits of ageing was dramatically reduced in the group of mice treated with the compound - artificial antioxidant SkQ1, showed the results of the study published in the journal Aging.
This compound -- that appears to work by protecting animal cells from the toxic byproducts of mitochondria, known as intracellular powerstations -- was developed in the Moscow State University by Russian biologist Vladimir Skulachev.
"Our study opens the way to the treatment of ageing with mitochondrially targeted antioxidants," Skulachev, a co-author of the study, said.
Experiments involved a special strain of genetically-modified mice created and characterised in Sweden.
A single mutation was introduced into genome of these mice resulting in the substantially accelerated mutagenesis in mitochondria which leads to accelerated ageing and early death of the mutant mice. They live less than one year (normal mouse lives more than two years).
The mutation promotes development of many age-related defects and diseases indicating that the major defect of these mice is indeed ageing.
Starting from the age of 100 days one group of mutant mice was treated with small doses of SkQ1 (approximately 12 micrograms) added into their drinking water.
Another group of animals served as a control group receiving pure water.
Differences between the two groups became obvious starting from the age 200-250 days.
Animals in the control group aged rapidly as expected. They were losing weight, their body temperature decreased, severe curvature of the spine (as a result of osteoporosis) and alopecia were developing, their skin became thinner, and in case of females estrus cycle was impaired.
Finally their mobility and oxygen consumption were decreased.
The development of all these typical traits of ageing was dramatically decelerated in the group treated with SkQ1.
Some of the ageing traits did not appear in that group at all, the study said.
This work "clearly demonstrates the key role of mitochondrially produced reactive oxygen species (free radicals) in the process of ageing of mammals", Skulachev said.
An oral form of the compound is now in the process of clinical trials in Russia.
The researchers believe that in case of positive results of these trials, such "anti-ageing" drug can be approved for use in two to three years.

London, Feb 17 (IANS) A fat pay cheque may be influenced by more than just physical attractiveness or the lack of it, say researchers dispelling the 'beauty premium' theory which says beautiful people earn more while those who are not so gorgeous are paid less.
The findings showed that healthier and more intelligent people and those with more conscientious, more extraverted and less neurotic personality traits are the ones who take fatter pay checks home.
"Physically more attractive workers may earn more, not necessarily because they are more beautiful, but because they are healthier, more intelligent and have better personality traits conducive to higher earnings, such as being more conscientious, more extraverted and less neurotic," said Satoshi Kanazawa from the London School of Economics and Political Science.
Economists have widely documented the "beauty premium" -- or, conversely, the "ugliness penalty" -- on wages.
Population-based surveys in the US and Canada for instance showed that people who are physically attractive earn more, while those who are aesthetically compromised earn less.
For the study, detailed in the Journal of Business and Psychology, the team analysed a nationally representative sample from a US data set that measured physical attractiveness of all respondents on a five-point scale at four different points in life over 13 years.
The beauty premium theory was dispelled when factors such as health, intelligence, and major personality factors together with other correlates of physical attractiveness were taken into account.
The analysis showed that people are not necessarily discriminated against because of their looks.
In addition, the study also offered narrower categories of relative attractiveness, with less attractive participants split into "very unattractive" and "unattractive."
The differentiation revealed an apparent ugliness premium, with very unattractive people earning more than their merely unattractive peers, the researchers said.

London, Feb 17 (IANS) Antibiotics may be an effective treatment for acute non-complicated appendicitis in children, instead of surgery, a study says.
The condition, which causes the appendix -- a small organ attached to the large intestine -- to become inflamed due to a blockage or infection, affects mainly children and teenagers.
Appendicitis is currently treated through an operation to remove the appendix, known as an appendicectomy.
"Acute appendicitis is one of the most common general surgical emergencies worldwide and surgery has long been the gold standard of treatment. But it is invasive and costly, not to mention extremely daunting for the child concerned and their family," said lead researcher Nigel Hall, Associate Professor of Paediatric Surgery at the University of Southampton in Britain.
"Our review shows that antibiotics could be an alternative treatment method for children," Hall noted.
For the study, the researchers assessed existing literature published over the past 10 years that included 10 studies reporting on 413 children who received non-operative treatment rather than an appendectomy.
The review published in the journal Pediatrics showed that no study reported any safety concern or specific adverse events related to non-surgical treatment, although the rate of recurrent appendicitis was 14 per cent.
"When we compared the adult literature to the data in our review it suggested that antibiotic treatment of acute appendicitis is at least as effective in children as in adults. This now needs to be explored more widely," Hall said.

Seoul, Feb 17 (IANS) Researchers have found that gene editing tool CRISPR-Cas9 can be delivered directly into the eye to treat age-related macular degeneration (AMD), an advance that may pave way for a new therapy for non-hereditary degenerative diseases.
It is estimated that almost one in every ten persons over 65 has some signs of AMD -- a form of blindness which causes distorted vision and blind spots.
In the study, scientists used CRISPR-Cas9 to perform "gene surgery" in the layer of tissue that supports the retina of living mice.
"We believe that this is a new therapeutic modality for the treatment of non-hereditary degenerative diseases," said Kim Jeong-Hun, Professor at Seoul National University in South Korea.
The most common retinopathies causing blindness are 'retinopathy of prematurity' in children, 'diabetic retinopathy' and 'AMD' in older adults.
In these diseases, abnormally high levels of a protein called Vascular Endothelial Growth Factor (VEGF) are secreted which leads to leakages of blood and fluid into the eye, damaging an area at the centre of the retina called macula.
Currently, injections of anti-VEGF drugs are the most common treatment against AMD.
"The injections tackle the effects, but not the main cause of the problem. By editing the VEGF gene, we can achieve a longer-term cure," added Kim Jin-Soo, Director of the Center for Genome Engineering at the Institute for Basic Science (IBS) in South Korea.
The CRISPR-Cas9 system works by cutting DNA at a target site, inside the VEGF gene.
For the study, published in the journal Genome Research, the team injected the pre-assembled CRISPR-Cas9 complex into the eyes of a mice model.
They found that the delivering CRISPR-Cas9 complex was more efficient, modified only the VEGF gene and did not affect other genes.

Washington, Feb 17 (IANS) In line with its shift in focus from low-Earth orbit to deep space missions, NASA has selected proposals for the creation of two multi-disciplinary, university-led research institutes that will focus on the development of technologies critical to extending human presence deeper into our solar system.
The new institutes will advance NASA's aim of developing technologies that will allow long-duration mission crews to manufacture the products they need, rather than relying on the current practice of resupply missions from Earth.
The new Space Technology Research Institutes (STRIs) created under these proposals will bring together researchers from various disciplines and organisations to collaborate on the advancement of cutting-edge technologies in bio-manufacturing and space infrastructure.
The goal is to create Earth-independent, self-sustaining exploration mission capabilities, NASA said in a statement.
"NASA is establishing STRIs to research and exploit cutting-edge advances in technology with the potential for revolutionary impact on future aerospace capabilities," said Steve Jurczyk, Associate Administrator for NASA's Space Technology Mission Directorate in Washington.
"These university-led, multi-disciplinary research programs promote the synthesis of science, engineering and other disciplines to achieve specific research objectives with credible expected outcomes within five years," Jurczyk added.
Each STRI will receive up to $15 million over the five-year period of performance, said NASA .
