Scientists at Nanyang Technological University, Singapore
(NTU) have developed
a new camera technology that can take sharp, colour images without using a lens
and colour filters.
A conventional camera utilises optics made from glass or
plastic lenses to capture light and guide it onto colour filters and camera
sensor in order to obtain sharp colour images. These lenses are usually bulky
in size and expensive due to the precision manufacturing required.
The scientists created multi-coloured images by using only a
piece of ground glass and a monochrome (black and white) sensor and ‘reverse
engineering’ the light that is scattered by the translucent matt surface of the
ground glass. Since different wavelengths of light are scattered differently by
the ground glass, an algorithm was created to reconstruct the original image
that was projected on to the ground glass.
The scientists created a library of ‘speckle patterns’
linked to each wavelength of light, including those in the infrared and
ultraviolet spectrums which are not visible to the naked eye.
Professor Yoon Soon
Fatt, Chair of NTU’s School of Electrical and Electronic Engineering, noted
that the innovation was the result of interdisciplinary research involving both
physics and photonics engineering.
“How light interacts with objects change with varying
wavelengths, so our scientists had to think out of the box, in order to design
a camera not limited by the typical red, green and blue spectrums. This
research is an example of how advanced photonics research can lead to potential
improvements to diagnostics, sensing and surveillance technologies,” Prof Yoon
The project was led
by Assistant Professor Steve Cuong Dang from the NTU School of Electrical and Electronic Engineeringand it took himand his researchers, Dr Sujit Kumar Sahoo, and Dr Tang Dongliang, over a year of research and development.
By removing the need for a lens and colour filters and
replacing them with ground glass, this innovation could potentially make
compact cameras and smart phones slimmer.
This is also much more cost-effective compared to existing
multispectral cameras on the market.
In addition, this new imaging technique could also help to
improve imaging applications in biomedical and scientific applications, as the technology
can reconstruct images in other multiple wavelengths invisible to the naked
eye, like infrared and ultraviolet. These are used for imaging purposes in
medicine, surveillance and astrophysics. The technology can also reconstruct
images taken at the microscopic scale.
Assistant Professor Dang said,
“The unique feature of our camera is that it can capture any range of light
spectrum, unlike existing cameras on the market which are pre-fixed. It is also
less affected by optical alignment issues like conventional cameras, because
there are no moving parts and no focusing optics.”
This camera could also be used in areas like food safety, where
one can take a photo of fruits or meat in particular spectra to look for spots
that are associated with chemicals or bacterial activity leading to spoilage.
For instance, the research team used their technique to
distinguish between two different apple juices which look identical to the
naked eye but have different colour spectrums signalling their difference in
ingredient or freshness.
It could also be used in forensics, as the camera could be
tuned to capture a wide spectrum, including near infrared and ultraviolet, to
reveal clues or evidence invisible under normal circumstances.
A patent has been filed for this new technology by NTU’s
innovation and enterprise arm, NTUitive.
Supported by NTUitive and the LUX Photonics Consortium, the
team received keen interest from industry players and potential adopters to
further develop this technology in the fields of vision correction and chemical
sensing. The research team plans to engage industry partners to explore adaptation
of their technology for real-world applications.
This innovation was featured on the cover of the scientific
journal, Optica, in Oct 2017.
A research team from the LKS Faculty of Medicine at The University of Hong Kong (HKUMed) has developed more efficient CRISPR-Cas9 variants that could be useful for gene therapy applications. By establishing a new pipeline methodology that implements machine learning on high-throughput screening to accurately predict the activity of protein variants, the team has expanded the capacity to analyse up to 20 times more variants at once without needing to acquire additional experimental data, which vastly accelerates the speed in protein engineering.
The pipeline has been successfully applied in several Cas9 optimisations and engineered new Staphylococcus aureus Cas9 (SaCas9) variants with enhanced gene editing efficiency. The findings are now published in Nature Communications and a patent application has been filed based on this work.
Staphylococcus aureus Cas9 (SaCas9) is an ideal candidate for in vivo gene therapy owing to its small size that allows packaging into adeno-associated viral vectors to be delivered into human cells for therapeutic applications. However, its gene-editing activity could be insufficient for some specific disease loci.
Before it can be used as a reliable tool for the treatment of human diseases, further optimisations of SaCas9 are vital within precision medicine. These optimisations must comprise the boosting of its efficiency and precision by altering the Cas9 protein.
The standard protocol for modifying the protein involves saturation mutagenesis, where the number of possible modifications that could be introduced to the protein far exceeds the experimental screening capacity of even the state-of-art high-throughput platforms by order of magnitude.
In their work, the team explored whether combining machine learning with structure-guided mutagenesis library screening could enable the virtual screening of many more modifications to accurately identify the rare and better-performing variants for further in-depth validations.
The machine learning framework was tested on several previously published mutagenesis screens on Cas9 variants and the team was able to show that machine learning could robustly identify the best performing variants by using merely 5-20% of the experimentally determined data.
The Cas9 protein contains several parts, including protospacer adjacent motif (PAM)-interacting (PI) and Wedge (WED) domains to facilitate its interaction with the target DNA duplex. The research team married the machine learning and high-throughput screening platforms to design activity-enhanced SaCas9 protein by combining mutations in its PI and WED domains surrounding the DNA duplex bearing a (PAM). PAM is crucial for Cas9 to edit the target DNA and the aim was to reduce the PAM constraint for wider genome targeting whilst securing the protein structure by reinforcing the interaction with the PAM-containing DNA duplex via the WED domain.
In the screen and subsequent validations, the researchers identified new variants, including one named KKH-SaCas9-plus, with enhanced activity by up to 33% at specific genomic loci. The subsequent protein modelling analysis revealed the new interactions created between the WED and PI domains at multiple locations within the PAM-containing DNA duplex, attributing to KKH-SaCas9-plus’s enhanced efficiency.
Until recently, structure-guided design has dominated the field of Cas9 engineering. However, it only explores a small number of sites, amino-acid residues, and combinations. In this study, the research team was able to illustrate that screening with a larger scale and less experimental efforts, time and cost can be conducted using the machine learning-coupled multi-domain combinatorial mutagenesis screening approach, which led them to identify a new high-efficiency variant KKH-SaCas9-plus.
The Assistant Professor of the School of Biomedical Sciences, HKUMed stated that this approach will greatly accelerate the optimisation of Cas9 proteins, which could allow genome editing to be applied in treating genetic diseases more efficiently.
To preserve and propagate the species in the typhoon-affected Cagayan Valley and to investigate bamboo’s potential for use in the pharmaceutical and industrial industries, phytochemical screening and DNA barcoding of economically significant bamboos will be conducted in the Philippines.
There are several benefits of using bamboo in the food, medicinal, phytochemical, medical, and industrial sectors, according to Alvin Jose L. Reyes and Eddie B. Abugan Jr from the Project Management Division (PMD) of the Department of Environment and Natural Resources (DENR)-Foreign Assisted and Special Projects.
They explained that seeds or living cells containing genetic resources beneficial for plant conservation and breeding are called germplasms. The DENR-PMD staff clarified that the classification of bamboo germplasm is an essential correlation between the preservation of diversity and utilisation of germplasm.
A study dubbed the Bamboo Characterisation Project of the Cagayan State University (CSU)-Gonzaga was recently presented to the DENR Protected Area Management Board (PAMB) in the province of Sta. Ana, Cagayan through its project leader Jeff M. Opeña. It has to do with its request for a free permit to carry out the bamboo characterisation and sample collecting tasks on the protected landscape and seascape of Palaui Island.
The CSU-Gonzaga research lab will also be renovated as part of the project. In the province of Cagayan, it will collect and classify various species in various environments. Furthermore, a contemporary and inventive method of classifying bamboo species will be DNA barcoding. It will speed up the process of experts identifying the species they want to utilise based on characteristics like quick reproduction or medicinal properties.
Bamboo has traditionally been classified according to how frequently or abundantly it flowers -annually, sporadically, or regularly, and gregariously. However, the demand for a long period of time, which might occur over years or even decades, made floral morphology description a limitation and a challenge.
On the other hand, professionals in pharmaceuticals and medicine can find plant secondary metabolites in bamboo that have application potential in the business through biochemical characterisation by phytochemical (plant chemistry) screening.
While secondary plant metabolites such as anthocyanins, alkaloids, flavonoids, saponins, phenols, steroids, tannins, and terpenoids are explored for medical plant herbal reasons, among other prospective commercial uses, primary metabolites comprise tiny molecules like amino acids and carbohydrates.
Additionally, Executive Order 879 required that 25% of the Department of Education’s annual supply of school desks be constructed of bamboo. Philippine Bamboo Industry Development Council (PBIDC) is created by Executive Order 879.
According to a direction sent to the DENR’s Forest Management Bureau, Laguna Lake Development Authority, and Mines and Geosciences Bureau, bamboo should be planted in the agency’s own reforestation zones.
In addition to reducing typhoon flooding, DENR wants to employ bamboo as a strategy for reducing climate change. Per hectare of a plantation, bamboo is known to absorb five metric tonnes of carbon dioxide. Bamboo is being planted in the Bicol and Marikina rivers, which are typically inundated during typhoons. Using engineered bamboo, DENR is also advocating its usage as a lumber replacement.
The first bamboo species studies to consider the various habitats where bamboo grows in the province of Cagayan are the phytochemical and morphological studies of bamboo species. The Smith Volcano, also known as Mount Babuyan, which is politically located in Calayan Island, and Mount Cagua in Gonzaga are the two volcanoes that the study of bamboo species growth will focus on.
Coastal locations, residential areas, grasslands, agroecosystems, next to water bodies, caverns, close the volcano, rainforests, islands, protected regions, and other habitats will be researched for the bamboo species using DNA barcoding.

Researchers at the Massachusetts Institute of Technology (MIT) demonstrated a robotic arm that searches for things hidden by radio frequency (RF) marks, which reflect signals from an antenna, using both optical information and RF waves.
They have now developed a new system that can efficiently retrieve any object buried in a pile based on their previous work. If some of the items in the pile have RFID tags, the system does not need to tag the target item to recover it.
The system’s algorithms, known as FuseBot, reason about the likely location and orientation of objects beneath the pile. FuseBot then determines the most efficient method for removing obstructing objects and extracting the target item. FuseBot was able to find more hidden items than a cutting-edge robotics system in half the time.
This speed could be particularly beneficial in an e-commerce warehouse. According to senior author Fadel Adib, associate professor in the Department of Electrical Engineering and Computer Science and director of the Signal Kinetics group in the Media Lab, a robot tasked with processing returns could find items in an unsorted pile more efficiently using the FuseBot system.
More than 90% of U.S. stores already utilise RFID tags, according to recent market analysis, but since the technology is not widespread, only some items inside piles may be tagged. This issue served as the group’s research’s impetus.
With FuseBot, a robotic arm retrieves an untagged target object from a jumbled pile using an attached video camera and RF antenna. To produce a 3D model of the surroundings, the system scans the pile with its camera.
It simultaneously transmits signals to find RFID tags from its antenna. Since most solid objects can be penetrated by these radio waves, the robot can “see” deep inside the pile. FuseBot is aware that the target object cannot be found in the exact same location as an RFID tag because it is not marked.
Since the robot is aware of the target item’s size and shape, algorithms combine this data to update the 3D model of the surroundings and suggest suitable spots for it. The system then uses the pile of things and the positions of the RFID tags to decide which item should be removed to locate the target item quickly.
The robot doesn’t know how the components are arranged underneath the pile or how a flimsy object can be distorted by rubbing against bigger others. By leveraging its knowledge of an object’s size, shape, and the location of its RFID tag to create a model of the 3D space that object is most likely to occupy, it overcomes this difficulty via probabilistic reasoning.
It utilises logic to determine which thing would be “better” to eliminate next as it removes objects. After removing one item, the robot scans the pile once more and adjusts its plan considering the new knowledge.
Compared to the other robotic system’s 84 per cent success rate, FuseBot removed the target object successfully 95 per cent of the time. It was able to identify and collect the targeted goods more than twice as quickly and did it with 40% fewer moves.
The software that does the complicated reasoning for FuseBot may be built on any computer; it only needs to interact with a robotic arm that has a camera and an antenna.
FuseBot will soon feature more intricate models that the researchers hope will improve its performance with deformable things.
Advances in LED technology as a light source have made it possible to design lights based on how they look to the human eye. What was once just a theory can be proven true when a solid-state light source is present.
“To test lamps and luminaires, two tools called integrating-sphere and type C goniophotometer are used,” says Dr Revantino, ST, MT, Sub Coordinator of Electricity and Battery, Ministry of Industry of the Republic of Indonesia, and an alumnus of Bandung Institute of Technology (ITB).
Changing the strength of the individual colour chips in an LED light, which is called “tuning,” can make the spectrum of the light change. This gives users the freedom to choose the colour of the light based on their tastes, but it also changes how the colour of the object looks.
The Physical Engineering Vocational Body of the Indonesian Engineers Association (BKTF-PII) held a sharing session on the topic “Spectral-Based Lighting” to talk about the progress of LED technology.
If the spectral reflection properties of an object are known, the spectral interaction method can be used to simulate how the colour of an object will look under a certain LED light spectrum. This is useful in lighting situations where the colour of the object needs to be brought out so that it looks right. This is a step toward the Lighting 4.0 era, which is all about putting people at the centre of lighting.
Solid-state lighting is one type of lighting that is based on the colour of light. Solid-state lighting is a kind of lamp that gets its light from light diodes, organic light diodes, or polymer light diodes. This type of lamp is called a “solid lamp” because it doesn’t have gas or electric filaments like most lamps. This sturdy lamp has a lot going for it. From an economic point of view, flexibility can open the door to theoretical validation, and in the last ten years, it has grown very quickly.
To help with Industry 4.0, technology is also improving in the lighting industry. This is shown by the presence of spectral-based lighting, which is part of the Lighting 4.0 innovation – as an enabler, flexibility in light control, and human-centred lighting.
Data Engineering in Industry 4.0
“Data is the new oil” has become a popular saying in the world of technology. Data must be used to make decisions and make predictions about the future of a company or even an industry. In the world of technology, many sciences and jobs that deal with data are also growing quickly. From a Data Scientist to a Data Analyst to a Data Engineer.
Data Engineering is a subfield of software engineering that focuses on building data systems and infrastructure. Data engineering focuses on how data scientists can quickly and correctly get to the data they need, on the other hand, data engineers are usually in charge of building systems or infrastructure that deal with large amounts of data.
Data engineers have a role in the industrial world. They help solve problems that come up in the industrial world. In the process of digitalising an industry, there are steps that must be taken. Starting with system integration, visibility of operations, data analysis, and operational optimisation.
Several real-world solutions, from different stages of flow to digital parts that can shape the digitalisation of industry, have been created. Starting with operational intelligence, operator assistance, digital maintenance, energy management, condition monitoring, a training portal, quality management, and inventory management. These different solutions that have already been put in place can help users learn how to use Industry 4.0 empowerment technology effectively in Indonesia.

Researchers have developed a reusable, recyclable, washable, odourless, non-allergic, and anti-microbial N95 mask by using 3D printing technology. The multi-layer mask has a shelf life of more than 5 years, depending upon the use. The outer layer is made up of silicon.
Apart from its well-known uses to prevent infections like COVID-19, the mask can also be used in industries where workers are exposed to high volumes of dust like cement or cotton factories, brick kilns, and paint industries. It can be modified according to the requirement by changing the filter configuration. As per a government press release, the mask can help prevent severe lung diseases such as silicosis. A trademark and a patent have also been filed for the mask called Nano Breath.
The mask consists of a 4-layer filtration mechanism wherein the outer and first layer of the filter is coated with nanoparticles. The second layer is a high-efficiency particulate absorbing (HEPA) filter, the third layer is a 100 µm filter, and the fourth layer is a moisture absorbent filter.
A Zetasizer Nano ZS, a facility supported by the government’s Fund for Improvement of Science & Technology Infrastructure (FIST) project, was used to carry out the work. It enables high-temperature thermal analysis for ceramic materials and catalysis applications. It is a high-performance, versatile system for measuring particle size, zeta potential, molecular weight, particle mobility, and micro-rheology.
Technology has played a significant role in the fight against the COVID-19 pandemic over the past two years. Indian institutes have invested resources in developing tech-enabled solutions for the new normal. Earlier this year, researchers from the Indian Institute of Technology in Jodhpur (IIT-Jodhpur) created an artificial intelligence (AI) model that can detect COVID-19 by examining the chest X-ray of patients. The team proposed a deep learning-based algorithm called COMiT-Net, which learns the abnormalities present in the chest X-ray images to differentiate between an affected lung and a non-affected lung. It can also identify infected regions of the lungs.
In March, Bengaluru-based scientists from the Centre for Nano and Soft Matter Sciences (CeNS) and the Jawaharlal Nehru Centre for Advanced and Scientific Research (JNCASR) developed an affordable solution to develop low-cost touch-cum-proximity sensors, popularly called touchless touch sensors, through a printing technique. The scientists set up a semi-automated production plant to produce printing-aided patterned transparent electrodes (a resolution of around 300 micrometres). It has the potential to be utilised in advanced touchless screen technologies. It could be used for self-service kiosks, ATMs, and vending machines.
As OpenGov Asia reported, the team fabricated a touch sensor that can sense a proximal or hover touch even from a distance of 9 centimetres from the device. The team also announced they would make several more prototypes using their patterned electrodes to prove their feasibility for other smart electronic applications. Industry players and research institutions and labs can access the technology on a request basis and through collaborative projects. The patterned transparent electrodes could be used in advanced smart electronic devices like touchless screens and sensors.
