Visuals are most powerful tools for long-term memory and learning. It makes complete sense as our brain mainly works as an image processor. A major part of our sensory cortex is devoted to vision. Interestingly, the portion of the brain which is involved in the processing of words is quite small in comparison to the part that processes visual images.

Researcher turned Edu-entrepreneur Mr. Vijay Kantharia- understood the importance of visuals watching and learning, especially through TV advertisements (Ads). He realized that TV Ads are wasting so much time, and strategically he came up with a brilliant idea- to replace the TV ads with educational videos, and have founded a startup with name Cerebroz EduTree.

On 11th of February 2018, CEREBROZ EDUTREE, Surat- has officially launched their unique device- EduTree at Gandhi Smruti Bhavan, Surat (Gujarat). This grand launching was attended by hundreds of curious parents, teachers, and students who were also offered a discount on the basic price of the device on pre-booking. Organizers say they have received a huge response from the public, and on launching day, they have pre-booking worth more than INR 5 Lacs.

EDUTREE- World's first TV Ad Replacer

EDUTREE device, which is first of its own kind, has many advanced features and it is very easy and user-friendly. This startup claims that EDUTREE is the World's first TV Ad Replacer, Converting an idiot box to a Genius box. EduTree replaces TV Ads with comprehensive K12 educational videos or other customized informative videos, saving kids from harmful effects of commercials while simultaneously educating them. EduTree can also be used as Wi-Fi router, and also eliminates the need of educational tablets.

Television is controlling our minds

“Television is controlling the brain of masses and specifically growing children. Kids are the great imitator. Whatever, we are watching and hearing that will stay in mind for the longest time or for last ever. With the same concept when TV ads will be replaced by educational content that will be inculcated in children’s mind easily. As children remember TV ads or Songs so easily without giving much effort, the same way they can memories customizable educational content. TV ads are not that much help for kids, and with this idea, this revolutionary product came into existence,” said Vijay Kantharia, Founder of Cerebroz EduTree starts up.

How EduTree works?

EduTree receives inputs from the set-top box directly into its specially designed Chip. An inbuilt sensitive system processes the signals and replaces TV ads with educational videos stored inside it. Ads are playing as it is on TV in the background that you can see in the PIP mode. After few seconds the PIP mode disappears from the screen which allows a complete view of strikingly conceptualized educational videos.

“With just the hovering of a mouse, PIP mode comes back alive giving you a peace of mind that you don’t miss any of your programs, but instead of repetitive ads you remember educational content,” said Vijay.

This unique device would not only help parents to control their child’s addiction of TV but other features like performance report would help to track the child’s activity like duration of watching TV and internet surfing etc.

New Technology May Help Scale Up Memory Storage Capacity

Researchers at Indian Institute of Technology Hyderabad have demonstrated the control of resistive switching characteristics of titanium dioxide- based resistive random access memory device with the magnetic field.

Silicon-based memory devices such as hard drives and flash drives are in high demand for gadgets that require storage. Conventional semiconductor material-based memory devices have limited scale-up ability to increase their storage capacity. Hence, there is a quest in developing new memory technologies with superior characteristics. In this direction, a group of Indian researchers has developed a new type of resistive random access memory (RRAM) device that can be controlled with magnetic fields.

Researchers at Indian Institute of Technology Hyderabad have demonstrated the control of resistive switching characteristics of titanium dioxide- based resistive random access memory device with the magnetic field. The team has designed a memory device which is made up of silver, titanium dioxide and fluorine doped Tin oxide (FTO).

Non-volatile memory devices such as flash memory and magnetic random access memory (MRAM) are key components in many technological devices like hard drives on a computer and memory cards in a phone. Non-volatile memory is typically used for storing information that would be retained even after power is switched off. Ideally, a good memory device should be able to operate with high speed, low power consumption and must possess high density.

Study suggests that the data transport properties (resistive switching behaviour) in the currently available RRAM based device are mainly controlled by voltage. It would help if resistance switching behaviour can be controlled with magnetic field, light and temperature. Researchers say they are exploring magnetic fields because that would give an opportunity to control transport in a remote way.

According to researchers, RRAM devices were fabricated on FTO substrate to study the resistive switching behaviour in the newly designed device. To build this new device, titanium dioxide paste was used to prepare a thin film on FTO substrate which was followed by heating of film at the very high temperature (400 degrees C). “We used silver as the top electrode for good conduction as well as its anti-oxidation property whereas fluorine-doped tin oxide was used as the bottom electrode,” said researchers.

“As present memory technologies are approaching their scaling limits, we need intensive research to develop non-volatile memory technologies. Among various NVM technologies, resistive random access memory (RRAM) also has attracted a great deal of scientific and technological interest owing to its easy fabrication, high density, and promising performance,” said Dr. S. N. Jammalamadaka, who did the study along with Dwipak Prasad Sahu.

This finding may be helpful in future RRAM-based storage devices which could be operated with magnetic fields. The study was recently published in journal Scientific Reports.

Scientists Uncover Mechanism Of Joint Cartilage Formation

Researchers have reported the role of two novel molecules – NFIA and GATA3 – in development of joint cartilage during embryo growth.

Joint pain due to osteoarthritis is an emerging health problem. Researchers are engaged in developing new strategies for osteoarthritis treatment based on regenerative medicine, tissue engineering, and gene therapy. Now Indian researchers have made headway towards finding a molecule that can stop degeneration as well as promote regeneration of articular cartilage.

Researchers at the Indian Institute of Technology Kanpur have reported role of two novel molecules - NFIA and GATA3 - in development of joint cartilage during embryo growth. They have observed in chicken and mouse studies that both these molecules prevent cartilage degeneration. In addition, GATA3 can also promote formation of articular cartilage, which covers ends of joints. Deterioration of articular cartilage in joints causes osteoarthritis. The results of the study have been published in journal Development

“We have identified and characterized roles of two novel articular cartilage factors - NFIA that prevents degeneration of cartilage and maintains it permanently throughout life; and GATA3 that is not only necessary to prevent cartilage degeneration but also can induce articular cartilage, in collaboration with other factors,” explained Dr. Amitabha Bandyopadhyay, who led the research team.

Previous studies suggest that genes involved in tissue repair and regeneration are largely similar to the ones associated with tissue building during embryo development. In an earlier study, this group had reported a collection of genes that are turned on exclusively during embryonic articular cartilage development. 

In this study, the authors also observed interesting phenomena where molecular manipulation leading to perturbance of articular cartilage also led to a defect in transient cartilage formation. Pratik Singh, co-author of this study says “this study provides novel insight into the cross-talk between articular cartilage and transient cartilage formation which is essential for successful development of limb skeleton. By studying these molecules further we hope to learn to make stable articular cartilage in vitro, currently a major challenge in the field.” 

“The work provides important pieces in the puzzle of how joints are initially formed in the body,” commented Dr. Terence D. Capellini of Human Evolutionary Biology department of Harvard University, who was not connected with the study.

“We know that joint cartilage is different from other cartilage. It has a different tensile strength and unlike skeletal cartilage, it is resistant to ossification. This new work is going to be the first step in identifying how these differences are established at the molecular level,” said Dr. Raj Ladher from National Centre for Biological Sciences, Bangalore. He is not a part of this study.

“Despite the importance of joint/articular cartilage in normal physiology and disease conditions, very little is known about how it develops and is maintained permanently as cartilage throughout life. This limited understanding is perhaps why there is no effective strategy to treat osteoarthritis,” said Dr. Amitabha Bandyopadhyay, who led the research team. 

The research team included Pratik Singh, U. S. Yadav, K. Azad and Amitabha Bandyopadhyay (IIT- Kanpur) Pooja Goswami (KIIT University, Bhubaneswar), Veena Kinare (Sophia College for Women, Mumbai). 

The work was supported by grants from the Department of Biotechnology (DBT) and Science and Engineering Research Board (SERB) of Department Science and Technology (DST).

Degenerative disc disease is a major cause of low back pain affecting the mobility of people. A group of Indian scientists have developed a silk-based bioartificial disc that may find use in disc replacement therapy in future.

At present, therapeutic treatment for degenerative disc disease can only provide symptomatic relief of pain without restoring the functions of discs, while disc replacement surgery is very costly. The use of a silk biopolymer to fabricate a biocompatible disc can reduce the cost of artificial discs in future, claim researchers from Department of Biosciences and Bioengineering at Indian Institute of Technology, Guwahati, who have developed the new technology. 

The group has developed a fabrication procedure for a silk-based bioartificial disc adopting a “directional freezing technique”. The disc mimics internal intricacy of the human disc and its mechanical properties too are similar to those of the native ones, according to research results published in international scientific journal Proceedings of the National Academy of Sciences (PNAS).

The fabricated discs supported primary annulus fibrosus or human mesenchymal stem cell proliferation, differentiation, and matrix deposition of a sufficient amount. The annulus fibrosus is a specialized tissue having a complex, multilamellar, hierarchical structure consisting of collagen, proteoglycans and elastic fibers.

“Major challenges toward successful intervertebral disc tissue engineering remain elusive, mainly because of tremendous complexity of annulus fibrosus tissues. We have successfully recapitulated its internal intricacy - angle-ply construct, which is critical for the proper biomechanical functioning of the disc,” Dr. Biman B. Mandal, who led the research team, told India Science Wire.

Degenerative disc disease affects intervertebral discs, which are soft pillow-like cushions between interlocking bones that structure human spine. These discs act as shock absorbers for the spine and support weight and complex motions of the spine. With growing age, these discs change from a flexible state that allows the smooth fluid motion to a stiff and rigid state restricting movement and resulting in discomfort or pain. “Our construct mimics native structure-function attributes of the disc and provides sufficient mechanical strength to function in load-bearing activities,” explained Bibhas K. Bhunia, co-author of the study.

The new disc has been tested in laboratory mice and scientists observed the negligible immune response. “We believe if the silk-based biodiscs transcends clinical translation, it can be an affordable option for disc replacement therapy in future,” said Dr. Mandal.

The research team included Bibhas K. Bhunia, Biman B. Mandala (IIT Guwahati) and David L. Kaplan (Tufts University, Medford). This work was supported by grants from the Department of Science and Technology (DST) and the Department of Biotechnology (DBT).
