The government is twisting science and mangling the concept of natural to force gene-edited foods, unlabelled, onto our plates.

Environment secretary George Eustice promotes gene editing as a precision scienceone that is all benefits, no downside. Much of the media has fallen for this reassuring but thoroughly fallacious sales pitch, when in fact genome editing is just another form of risky genetic engineering.

Gene editing isnt just a single snip or tweak. As well as any intended genetic modification, it invariably involves large numbers of unintended alterationsto the plant or animal in question.It can also entail multiple cuts into an organisms DNA and the insertion of foreign genes.

For instance, Professor Cathie Martin, who led the development of the gene-edited tomato that could be the first crop of its kind to go on sale in the UK, told The National thatthe process did insert foreign genes that were removed before the final plant was put to market.

And be in no doubt that, as the European Court of Justice has ruled, gene editing does indeed create genetically modified organisms (GMOs).

Yet if the UK government gets away with its new legislation, it would allow plants created using foreign genes to be classified as natural and they will be exempt from regulation and labelling.

This should alarm us. A recent experiment in the US serves as a timely warning of how this volatile technology produces unpredictable, negative and irreversible results.

Researchers at Georgia State University just reported on how their gene editing experiment to reduce aggression in hamsters misfired when their precision alterations instead bred ultra-vicious rodents.In other words, the scientists anticipated a favourable outcome, but got the opposite result.

In the realm of food, the most obvious risks of gene editing are the production of toxins and allergens that could wreak havoc with human and animal health. Who has an appetite for that?

Last years government consultation found 88% of citizens dont want gene-edited foods treated differently to other genetically modified products.

Is it any wonder that, very sensibly, no UK supermarket is willing to say it will stock gene-edited food?

The emergence of CRISPR technology, which can be used for gene modification and editing, has been revolutionary for the science community and research field due to its applications for disease and health. Additionally, combining nanotechnology and CRISPR can hold tremendous potential for widening the opportunities for versatile applications, from diseases to agriculture.

CRISPR is an acronym for clustered regularly interspaced short palindromic repeats and is a critical tool that can be used to find specific DNA within cells for the purpose of gene editing; this can also include turning a gene on or off without modifying the sequence.

Conventional gene therapy methods have taken researchers years to gain traction and can be quite expensive; however, the emergence of CRISPR has revolutionized this process into a cheaper and relatively simpler strategy for gene editing.

CRISPR Cas9 proteins found in bacteria can be programmed to find and bind to targeted DNA sequences by providing a complimentary piece of RNA, which can guide the tool for its purpose. Once found, the Cas9 protein can cut the target DNA, which during repair, can lead to mutations and the disablement and overall dysfunction of the gene.

Other types of applications for CRISPR can also include replacing dysfunctional genes, turning genes on and off, instead of modifying the DNA, and even modifying single nucleotide bases within the DNA sequence from one letter to another. However, these can have varying levels of difficulties in practice.

CRISPR/Cas9 delivery can be used for innovative cancer therapy; however, this would require the gene-editing tool to be delivered directly into target cancer cells, requiring the passing of physical barriers and maintaining functionality.

The strategies for delivery of the CRISPR system can include physical and viral vectors.

The physical vectors can include (i) microinjection, (ii) electroporation, and (iii) hydrodynamic delivery. These delivery methods have demonstrated efficiency within in vitro application; however, in vivo results have been more challenging.

Viral vectors have also been subject to challenges within in vivo applications, with limitations comprising immunogenic responses, high production expense, limited capacity with cargo packaging, as well as having possible effects outside of the target area.

Research into non-viral vectors and the possible use of nanotechnology to advance delivery has been explored as a result.

Non-viral nanotechnology-based delivery methods may include the use of nanocarriers, such as polymers, lipids, silica nanoparticles and metallic nanoparticles.

These have been revered for various applications in different fields due to their versatility and have also been used within cancer therapy due to advantages such as having low immunogenicity and a high cargo delivery capacity.

The high potential of the CRISPR/Cas9 system within clinical applications has been recognized globally by researchers, evident from 18 CRISPR-based clinical trials that have been launched since 2016, with almost half being a type of immunotherapy.

Additionally, the use of nanotechnology for furthering this gene-editing tool for diverse applications such as cancer, HPV treatment, as well as agriculture may advance the field of science and healthcare on a global scale.

A previous clinical trial has demonstrated the use of CRISPR/Cas9 on the human papillomavirus (HPV) that is associated with cervical cancer, where the correlated genes, E6 and E7, were destroyed to inhibit cancer cell proliferation and overall survival.

However, while trials have shown effective results, human safety remains a priority, with off-target effects and delivery being a concern for the CRISPR/Cas9 system.

The use of a lipid nanoparticle-based CRISPR/Cas9 system has recently been applied to treat transthyretin amyloidosis (ATTR), becoming the first clinical data of therapeutic gene editing within patients. This nanotechnology incorporation into CRISPR gene editing has demonstrated the potential of using nanotechnology to advance the treatment of genetic disorders through innovative delivery.

With the global CRISPR market being valued at $846.2 million in 2019 and estimations of $10,825.1 million by the year 2030, at a compound annual growth rate of 26.86%, this gene-editing tool is predicted to have a significant impact worldwide.

The potential of editing the genome to modify human disease and disorders may be a tangible reality in the near future, with clinical trials already launched and set in motion.

Additionally, the use of nanotechnology for this advanced gene-editing tool may aid in satisfying concerns over have off-target effects due to the precise targetability characteristic for which this innovative field is known.

The versatility of nanotechnology enables the possibility of aiding the field of medicine as well as other fields, such as agriculture. This is critical as CRISPR systems also face delivery challenges within plants and with the use of nanomaterials, these may be solved.

With the growth of the global population, the essential survival of plants has become even more imperative to sustain the global demand for food, therapeutics, and bioenergy.

Genetic engineering methods are not only significant for medicine, but also for one of the most critical elements of life, namely, plants, to ensure species survival, higher yield, and nutrient density.

Nanotechnology uses for interdisciplinary applications have become a common theme and the opportunities for advancing the lives and health of humans are a critical component for research. The use of nanotechnology-based CRISPR can only advance the field further, providing promising solutions for current challenges.

Thus far, researchers have not identified ancestral viruses that could have plausibly given rise to the SARS-CoV-2 virus that causes COVID-19so says a new report from the Scientific Advisory Group for the Origins (SAGO) of Novel Pathogens set up by the World Health Organization (WHO).

The report, however, notes that "the current available data on the closest related SARS-like viruses and susceptibility of many animal species to SARS-CoV-2 suggest a zoonotic source." Assuming a natural outbreak, horseshoe bats are a likely reservoir of the virus in the wild, although it could also have passed through an unknown intermediate species before infecting humans.

An alternative hypothesis is that the COVID-19 virus somehow escaped from the Wuhan Institute of Virology, whose researchers were known to be experimenting with coronaviruses. Although three of the 27 members of the SAGO objected to consideration of the "lab leak" theory for the possible origin of the COVID-19 virus, the report states that "it remains important to consider all reasonable scientific data that is available either through published or other official sources to evaluate the possibility of the introduction of SARS-CoV-2 into the human population through a laboratory incident."

Interestingly, a Chinese team reported the results of testing 1380 samples taken from the Huanan Seafood Wholesale Market, where the outbreak was first identified. None of the samples from 188 live animals sold as meat detected the presence of the COVID-19 virus, but the researchers did find it in 73 samples from the ground, sewer wells, and various containers. "Skeptics of the natural origin theory maintain the market cluster could merely be a superspreader event touched off when a person infected with a lab-escaped coronavirus visited it," noted Science back in February.

Further investigation into the lab leak hypothesis would require that the Chinese government provide "access to and review the evidence of all laboratory (both in vitro and in vivo studies) with coronaviruses including SARS-CoV-2-related viruses or close ancestors." Going forward, the SAGO would like to obtain more information about "the nature of the studies performed before the first reported COVID-19 cases in Wuhan and whether they involved reverse engineering or gain-of-function, genetic manipulation or animal studies with strains of SARS-like CoV."

WHO Director-General Tedros Adhanom Ghebreyesus sent two letters in February to Chinese Premier Li Keqiang and National Health Commission head Ma Xiaowei asking for any updates with respect to ongoing studies focused on the origins of the COVID-19 virus. However, the SAGO report notes that the Chinese government and researchers have "not provided any information related to studies conducted evaluating the laboratory hypotheses as a possible introduction into the human population."

The SAGO reports that it will remain open to "any and all scientific evidence that becomes available in the future to allow for comprehensive testing of all reasonable hypotheses," including the lab leak hypothesis.

The Chinese government's continued stonewalling of independent investigations of the origin of the COVID-19 virus strongly suggests that it has something to hide.

COVID-19 'Lab Leak' Origin Theory Merits Further Investigation, Says New WHO Report - Reason

ITHACA, N.Y.Graduating high school seniors lined up, smiled and posed with their diplomas on Monday at Ithacas Stewart Park to the joyous sound of applause as they were congratulated for receiving the New York State Seal of Biliteracy.

The seal is a unique distinction for graduating seniors in New York State. It requires a year of independent study in addition to their regular curriculum. Students journal, research, read, speak, and write, in English and the language which theyre pursuing proficiency in, and ultimately, give a formal presentation before a panel of judges to earn the seal, or seal the deal, so to speak.

Students dont necessarily need to have studied a language in the Citys School System to pursue the seal. In fact, Emily Ufford, the teacher that pushed for the introduction of the Seal of Biliteracy program to the school district, emphasized the importance of the program for students whose families speak different languages at home. Ufford said that connecting students with their heritage languages was the original inspiration for her to get the program going locally.

Your education news is made possible with support from:

Of the Ithaca City School Districts (ICSD) graduating seniors, 30 received the seal, conferring the states highest official distinction for proficiency in a second language. The seal was earned by 2 students attending Lehman Alternative Community School, and 28 from Ithaca High School. The seal of biliteracy was given to students proficient in languages ranging from Bulgarian, to Spanish, Russian, French, Hebrew, Chinese, as well as among others.

The final presentations students worked on had titles like: A Comparison of Bullying in Russian, French, and U.S. Schools; the Urban Rural Gap in U.S. and Spain; Sustainable Architecture in the U.S., France, and Senegal; Access to Music Education in the U.S. and Israel; or Similarities and Differences in American and German Genetic Engineering.

One student, Daniela Rivas, shared that for her final project compared the childhoods experienced at-large in the U.S. and El Salvador, where her family is from. She relied on help from her Mom while doing research, and said that project made her aware of the prevalence of child labor in El Salvador. While the year of independent study for the seal made Rivas become more familiar with the Spanish language, she said that her final project constituted the biggest takeaway of her experience earning the Seal of Biliteracy.

Shaqued Menda, a student whose Seal of Biliteracy was in Hebrew, said that she has remained verbally fluent in Hebrew since moving from Israel to the U.S. in early childhood, but she saw herself losing the ability to read and write in the language as shes grown up.

I lost my ability to read and write in Hebrew because growing up here I worked so hard to learn English [] I was motivated to be able to text my grandparents again. Its kind of difficult to call them whenever I want to because of the time difference, said Menda, excited to confirm that she achieved her goal of being able to keep in touch with distant relatives.

Sofia Trigueros-Ufford daughter of Emily Ufford earned a seal of biliteracy in Spanish, and shared that it allowed her to get even closer with her dad. It definitely made me able to connect to my Dad more. I feel like the mothers language is the one that children speak most at home, so it was a lot of English at home. My dad has always spoken Spanish to me, but I used to always respond in English. Her studying to pursue the seal shifted the language spoken at home to Spanish, which her mom is also fluent in.

Nomi Falk, a student who is the first in the school district to have ever earned the seal of biliteracy in three languages Hebrew, Spanish, and French looked at the program as a great opportunity for students to flex their linguistic muscles.

I think whats cool about the seal is that it isnt just a language learning opportunity, so much as a preening opportunity, said Falk, adding, It was a good opportunity to show off what we can all do.
