In what has been claimed to be the first use of gene editing technique CRIPSR for replacement of a defective gene associated with a sensory disease, researchers have repaired a genetic defect that causes blindness. The research that led to successful editing of defective genes responsible for retinitis pigmentosa (RP) – an inherited condition that causes the retina to degrade and leads to blindness in at least 1.5 million cases worldwide – was carried out using stem cells derived from a patient’s tissue. Published in Scientific Reports, the study paves the way for using CRIPSR therapeutically to treat eye diseases.

An international group of physics researchers have said that they are closer to changing everything we currently know as the building blocks of universe and that if the theory holds, it could effectively rewrite physics textbooks. Researchers, in a paper published online in the prestigious journal Physical Review Letters, have predicted that the structure of protons could be proven to change inside the nucleus of an atom under certain conditions. While this theorised change in the internal structure of protons has not yet been discovered, it is currently being put to the test at the Thomas Jefferson National Accelerator facility in the US, in experiments designed by this research team.

Researchers have developed a graphene-based coating that they have proved is effective at melting ice from a helicopter blade paving way for a real-time de-icer. The thin coating of graphene nanoribbons in epoxy has been developed by researchers at Rice University and in their tests, researchers show that the coating is capable of melting centimeter-thick ice from a static helicopter rotor blade in a minus-4-degree Fahrenheit environment. A small voltage was applied to the coating that delivered electrothermal heat — called Joule heating — to the surface, which melted the ice.

Researchers have, for the first time, mapped world's global nitrogen footprint revealing that United States, China, India and Brazil are responsible for 46 per cent of the world's nitrogen emissions. The map, created using data from 188 countries, reveals that it is the developing countries that embody large amounts of nitrogen emissions from their exports of food, textiles and clothing with Australia being one of the few wealthy nations that is a net exporter of nitrogen, because of the substantial agriculture industry. The study led by the University of Sydney's Integrated Sustainability Analysis team used an economic modelling to group the nitrogen footprint into top-ranking bilateral trade relationships. Researchers noted an increasing for nitrogen production and found developed nations largely responsible for emissions abroad for their own consumption. Further, significant nitrogen net importers were almost exclusively developed economies.

Researchers have reported a surprising chemical reaction in a prototype of lithium-air battery that they claim will solve the battery’s biggest drawback. Lithium-air batteries have been pegged as the next-generation batteries that have up to five times the energy density of today’s familiar lithium-ion batteries. However, the versions of the batteries that have been tested till date have stored and released energy from lithium peroxide, an insoluble substance that clogs the battery’s electrode. Scientists at the U.S. Department of Energy’s Argonne National Laboratory developed a prototype with surprising ability to produce only lithium’s superoxide, not peroxide, as the battery discharges. Lithium superoxide, unlike troublesome lithium peroxide, easily breaks down again into lithium and oxygen, thus offering the possibility of a battery with high efficiency and good cycle life.

Researchers have managed to find a lifeless part of Antarctic that is devoid of any microbial activity whatsoever. The findings of the study published in the ISME Journal have huge implications for search for life on Mars considering that there are places on Earth – a planet filled with life – that have no traces of life. The part of the Antarctic where researchers from McGill University, Canada have been working on for the last four years to find traces of life is known as University Valley located in the high elevation McMurdo Dry Valleys of Antarctica, where extremely cold and dry conditions have persisted for over 150,000 years.

In a blow to Indian cultural and traditional ways, Nobel laureate Venkatraman Ramakrishnan has lambasted homeopathy and astrology as bogus fields. Ramakrishnan, while speaking at the Panjab University at Chandigarh to deliver the Har Gobind Khorana lecture on ‘On Nobody’s Word: Evidence and Modern Science’, said that the two practices are not only useless but harmful as well and India should adhere to its constitution which calls for promotion of scientific temper appealing that India needs to cultivate a more rational outlook of such age old practices.

A new study has claimed that college students who indulge in excessive video game play are more capable of acting on suicidal thoughts. The claims have been put forward by a team of researchers through a study published in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. wherein they have claimed that suicide ideation and planning may be elevated among frequent video game players who indulge in gaming for more than five hours a day. The study basically links action video games, which usually involve violence and aggressive content, to acquired capability for suicide (ACS). While researchers found no significant association between overall hours of video game play and ACS, and gender did not make a difference, when focusing on the action category of video games, the relationship between hours of game play and ACS became significant.

Through a new paper Professor André Füzfa from the University of Namur claims that we can produce, detect and control gravity using existing technologies. Professor Füzfa has put together a proposal that holds the potential of revolutionizing physics and can even test theory of general relativity of Einstein. Currently employed passive mode of study of gravity motivated Professor Füzfa to take up the challenge and put forward a revolutionary approach of study — create gravitational fields at will from perfectly controlled magnetic fields and observe how these magnetic fields can bend space-time.

In a first kind of discovery in decades, researchers have created a new class of hybrid sound waves that are gentle enough to be used in biomedical devices. Known as "surface reflected bulk waves", the new class of sound waves are a hybrid of bulk waves and surface waves and have been created by a team at RMIT University in Melbourne, Australia. According to the team the new class of sound waves have already proved their worth in delivering vaccines and other drugs directly to the lung and are hopeful that their creation could lead to a revolution in stem cell therapy. As Dr Amgad Rezk, from RMIT's Micro/Nano Research Laboratory, explains, they have already dramatically improved the efficiency of an innovative new "nebuliser" that could deliver vaccines and other drugs directly to the lung in as little as 30 seconds [study abstract]. Researchers are hopeful that their work opens up the possibility of using stem cells more efficiently for treating lung disease enabling them to nebulise stem cells straight into a specific site within the lung to repair damaged tissue and this could be a real game changer for stem cell treatment in lungs as well as other organs.

Researchers have warned that harmful bacteria and pathogens like salmonella can survive in dry food products like cookies and sandwich crackers for months. The warnings are based on a study carried out by University of Georgia wherein they used five different serotypes of salmonella that had been isolated from foods involved in previous foodborne outbreaks. The researchers involved with the study were prompted to carry out their research after reports of increased number of outbreaks of foodborne diseases linked to low-water-activity, or dry, foods emerged.

According to a recently published study in Applied Physics Letters, boron nitride nanotubes (BNNTs) are much stronger than their carbon counterparts with the former offering more strength per unit of weight. Researchers have already been attracted to boron nitride for the fact that just like carbon it can form single-atom-thick sheets and can be rolled into cylinders to create nanotubes. The nanotubes by themselves offer the same level of strength as the legendary carbon nanotubes, but the real deal is when composite materials are created using these nanotubes that offer higher levels of strength.

The Oak Ridge National Laboratory has achieved the capability to produce plutonium-238 with the production of 50 grams of the material already completed. The production of the plutonium-238 sample effectively revives the capability that has been dormant for around 30 years since production of the material was stopped by Savannah River Plant in South Carolina in the late 1980s. The ORNL is optimistic that the important milestone of sample production of plutonium-238 paves way for regular production of the material that will ensure constant supply of the material for NASA's missions.

High-Speed Operando Tomography and Digital Volume Correlation have been used by a University College London-led team to show in real-time how lithium batteries degrade as they are used. Real-time 3D images of active commercial Li/MnO2 disposable batteries were captured using X-ray computed tomography (CT) and advanced digital volume correlation software. The images formed cross-section time-lapse videos showing the damage occurring on the electrodes inside the battery in real-time.

Researchers from Technical University of Denmark have invented a new technology that can print data and colour images of unprecedented quality and microscopic dimensions at mind-blowing resolution of 127,000 DPI. The technology has been developed by researchers from DTU Nanotech and DTU Fotonik and in their demonstration of the capability of their laser printing technology, they have reproduced a colour image of Mona Lisa which is less than one pixel on an iPhone Retina display. If we compare text and pictures printed on a weekly or monthly magazine, it is normally printed at just 300 DPI.
