Biochip Could Detect Multiple Viruses, Cancers, or Toxins in Minutes
Researchers at Stanford University have shown how to conduct thousands of rapid molecular screenings simultaneously, using light to identify target molecules snared on top of an array of tiny silicon blocks. The team used an optical detection approach that relies on metasurfaces, arrays of tiny silicon boxes—each roughly 500 nanometers high, 600 nanometers long, and 160 nanometers wide—that focus near-infrared light on their top surface. This focusing makes it easy for a simple optical microscope to detect the shift in the wavelength of light coming from each silicon block, which varies depending on what molecules sit on top.To test the idea, the researchers tethered single-stranded gene fragments 22 nucleotides long to the silicon boxes and immersed the array in a buffer solution. When they added the complementary DNA strands to the solution, the strands quickly bound to the tethered ones, shifting the wavelength of light emitted from the surface of each box. This device could detect the presence of as few as 4000 copies of target genes per microliter, a concentration typically present in a nasal sample from a person infected with SARS-CoV-2. The technique could enable detection of viral infections without first having to amplify the genetic material from a patient, and could have wider applications. A company has been formed to commercialize the new detectors, specifically aimed at detecting minute levels of proteins and other molecules that cannot readily be amplified to make them easier to detect. |

Novel Peptoid Molecules to Fight Viruses
Researchers at NYU have shown how a group of novel peptoid molecules inactivates several viruses, including Zika and chikungunya. Peptoids, which have similar chemical backbones to peptides, are better able to break through virus membranes and are less likely to degrade.The researchers investigated seven peptoids for antiviral effects against four viruses: three enveloped in membranes (Zika, Rift Valley fever, and chikungunya) and one without (coxsackievirus B3). The team found that the peptoids inactivated all three enveloped viruses -- Zika, Rift Valley fever, and chikungunya -- by disrupting the virus membrane, but did not disrupt coxsackievirus B3, the only virus without a membrane. Moreover, chikungunya virus containing higher levels of phosphatidylserine in its membrane was more susceptible to the peptoids. Preclinical studies are going on to evaluate the potential of these molecules in fighting viruses and to understand if they can overcome the development of resistance. The peptoid-focused approach could help in treating a wide range of viruses with membranes that can be difficult to treat, including Ebola, SARS-CoV-2, and herpes.

Continuous-flow Manufacturing of Essential Antibiotic Cefazolin
University of Tokyo researchers have manufactured cefazolin using a continuous-flow method which is cheaper, quicker, less wasteful and more flexible in terms of how much drug can be produced when it is needed. Cefazolin is so important to human health that it has been designated an essential medicine by the WHO. It is used to cure a broad range of ailments such as urinary tract, respiratory and joint infections, and to prevent infection after surgery.The team used two connected reactors to produce cefazolin from readily available commercial raw materials. The raw materials and reagents, which facilitate the reaction, were pumped into the first reactor, which looks like a coiled thin metal tube, before moving into a second reactor where another raw material was added. From there flowed the cefazolin. It was a challenge for the team to optimize the environment inside the reactors, i.e., the temperature, transfer speed and mixing ratio of reagents, etc., to be able to obtain a high-purity product at the end, particularly due to the complex structure of cefazolin. According to the researchers, this method was substantially superior to conventional batch manufacturing and could even be optimized further. Many compounds can be synthesized by continuous-flow methods, such as for agricultural use, and the realization of a low-carbon society.

Bacteria that Can Detect Tumor DNA
Scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can detect the presence of tumor DNA in a live organism. Their innovation, which detected cancer in the colons of mice, could pave the way to new biosensors capable of identifying various infections, cancers and other diseases.They used Acinetobacter baylyi, a bacterium which has the elements necessary for both taking up DNA and using CRISPR to analyze it. The researchers designed, built and tested Acinetobacter baylyi as a sensor for identifying DNA from KRAS, a gene that is mutated in many cancers. They programmed the bacterium with a CRISPR system designed to discriminate mutant from normal (non-mutated) copies of KRAS. This means that only bacteria that had taken up mutant forms of KRAS, as found in precancerous polyps and cancers, for example, would survive to signal or respond to the disease. The researchers are now adapting their bacteria biosensor strategy with new circuits and different types of bacteria for detecting and treating human cancers and infections.

New Light on Gene Therapy for Blood Disorders
Researchers have found new ways of treating blood disorders, such as sickle cell anemia, through gene therapy. The new research shows that blood stem cells can be genetically engineered while still in the bone marrow, in a single treatment. This technology can be used to correct disease-caused mutations such as the single mutation that causes sickle cell anemia in ~7.5 million people worldwide, and it can be used to control stem cells using messenger RNA (mRNA). To do this we utilized a type of nanoparticle similar to the Pfizer COVID mRNA vaccine but designed it to find these stem cells specifically. The risks patients undergo for gene therapy highlights the need for improved treatments. In addition, eliminating the need for stem cell collection and treatment outside the body can cut costs for patients and improve access to critical gene therapies for many patients.

IN BRIEF |
New COVID-19 subvariant EG.5 "Eris"
A new COVID subvariant, EG.5, also referred to as Eris, has emerged and become the dominant strain in the United States. EG.5 now accounts for the largest proportion of COVID-19 infections in the country compared to any other variant, according to the U.S. Centers for Disease Control and Prevention. On Aug. 9, the World Health Organization classified EG.5 as a variant of interest as cases increase globally. The EG.5 variant quickly overtook the prevailing omicron XBB strains in the U.S. last month. EG.5 is a descendant of the omicron XBB sublineage of the virus (specifically, XBB.1.9.2). It has an extra mutation in its spike protein, according to a WHO risk evaluation report. The variant was first detected in February 2023. So far, EG.5 has been detected in 51 countries — the majority of sequences are from China, followed by the U.S., South Korea, Japan and Canada, per WHO. XBB.1.16, also called the “Arcturus” variant, remains the most prevalent strain of COVID-19 worldwide.WHO considers the public health risk posed by EG.5 to be "low" and similar to that of XBB.1.16 and other variants of interest. The data available do not indicate that EG.5 causes a more severe infection compared to other variants, the experts note.

Ethanol to Revolutionize Nanosensor Manufacture
Macquarie University researchers have developed a new technique to make the manufacture of nanosensors far less carbon-intensive, much cheaper, more efficient, and more versatile, substantially improving a key process in this trillion-dollar global industry.The team has found a way to treat each sensor using a single drop of ethanol instead of the conventional process that involves heating materials to high temperatures. The new technique bypasses this heat-intensive process, allowing nanosensors to be made from a much broader range of materials.The new method was discovered accidentally, but the method's effectiveness depended on painstaking work to identify the exact volume of ethanol used - five microlitres. The team has patents pending for the discovery, which has the potential to make a very big splash in the nanosensor world. The Method has been tested with UV light sensors, and also with nanosensors that detect carbon dioxide, methane, hydrogen and more -- the effect is the same.

New recycling process for 'junk' plastic waste
University of Wisconsin-Madison chemical engineers are turning low-value waste plastic into high-value products.The new technique uses pyrolysis, in which plastics are heated to high temperatures in an oxygen-free environment. The result is pyrolysis oil, a liquid mix of various compounds. Pyrolysis oil contains large amounts of olefins.The team recovered olefins from pyrolysis oil and used them in a much less energy-intensive chemical process called homogenous hydroformylation catalysis which converts olefins into aldehydes, which can then be further reduced into important industrial alcohols.These products can be used to make a wide range of materials that are higher value.These higher-value materials include ingredients used to make soaps and cleaners, as well as other more useful polymers.The next step for the team is to tune the process and better understand what recycled plastics and catalyst combinations produce which final chemical products. |
New paint gives extra insulation
Stanford University scientists have invented a new kind of paint that can keep homes and other buildings cooler in the summer and warmer in the winter, significantly reducing energy use, costs, and greenhouse gas emissions.The newly invented paints have two layers applied separately: an infrared reflective bottom layer using aluminum flakes and an ultrathin, infrared transparent upper layer using inorganic nanoparticles that comes in a wide range of colors. For keeping heat out, the paint can be applied to exterior walls and roofs. Most of this infrared light passes through the color layer of the new paints, reflects off the lower layer, and passes back out as light, not being absorbed by the building materials as heat. To keep heat inside, the paints are applied to interior walls, where again, the lower layer reflects the infrared waves that transfer energy across space and are invisible to the human eye.Specifically, up to about 80% of high mid-infrared light is reflected by the paints, doing most of the work of keeping heat inside during cold weather and outside during hot weather.The research team tested their paints and found were 10 times better than conventional paints in the same colors at reflecting high mid-infrared light. |

Zaporizhzhya Nuclear Plant Changes Reactor Shutdown
The Zaporizhzhya Nuclear Power Plant in Ukraine has begun transitioning one of its 6 reactor units from a hot shutdown to a cold shutdown after a water leak was detected in one of its steam generators, said the International Atomic Energy Agency (IAEA).The purpose of placing reactor unit 4 in cold shutdown is to investigate the exact cause of the leak and carry out necessary maintenance to repair the affected steam generator. There was no radiological release to the environment, the IAEA noted, adding that over the next three days, the nuclear power plant will move unit 6 to hot shutdown to continue steam production. Unit 6 had been in cold shutdown since 21 April to facilitate safety system inspections and maintenance.The IAEA team on the site will closely monitor the operations for the transition between the shutdown states of Units 4 and 6. There were power disruptions after the 750kV power line disconnected twice on 10 August.The ZNPP had to rely on 330 kV backup line, to supply the electricity required, for example, to perform safety functions such as pumping cooling water for the plant; and there was no total loss of off-site power to the site and emergency diesel generators were not needed.The nuclear power plant has been experiencing major off-site power problems since the conflict began in February 2022, exacerbating the nuclear safety and security risks facing the site currently located on the frontline. Meanwhile, IAEA teams at other Ukrainian nuclear power plants – Khmelnitsky, Rivne, and South Ukraine, as well as the Chernobyl site – reported air-raid alarms on 9 August. They added that the safety and security at the facilities were not affected.

India eyes SMRs but focuses on large reactors
Minister of State Jitendra Singh has told the country's parliament that Small Modular Reactors (SMR) is a promising technology in industrial decarbonisation especially where there is a requirement of reliable and continuous supply of power. India is considering steps for development of SMR, to fulfil its commitment to Clean Energy transition. Detailed technical discussions are currently under way to plan a roadmap for studying the feasibility and effectiveness of deployment of such reactors. However growth of nuclear power capacity through large size reactors is still the primary goal.A report on the role of small modular reactors in the energy transition report on the role of small modular reactors in the energy transition issued earlier this year by the government's NITI Aayog public policy think-tank found that successful deployment of SMR technology must leverage private sector investment.The Government of India is exploring the options of collaborating with other countries and taking up indigenous development of SMRs, Singh told the Lok Sabha. Provisions of Atomic Energy Act, 1962 are being examined to allow participation of private sector and start-ups.
