Engineered bat virus stirs debate over risky research
Lab-made coronavirus related to SARS can infect human cells.
12 November 2015
An experiment that created a hybrid version of a bat coronavirus — one related to the virus that causes SARS (severe acute respiratory syndrome) — has triggered renewed debate over whether engineering lab variants of viruses with possible pandemic potential is worth the risks.
In an article published in Nature Medicine 1 on 9 November, scientists investigated a virus called SHC014, which is found in horseshoe bats in China. The researchers created a chimaeric virus, made up of a surface protein of SHC014 and the backbone of a SARS virus that had been adapted to grow in mice and to mimic human disease. The chimaera infected human airway cells — proving that the surface protein of SHC014 has the necessary structure to bind to a key receptor on the cells and to infect them. It also caused disease in mice, but did not kill them
Based on historical data, Australia and New Zealand (NZ) form a single epidemiological unit for cereal rusts. Until 2001, pathotype analysis of cereal rust pathogens for NZ was conducted at the University of Sydney, Plant Breeding Institute. The first year of pathotype analysis in New Zealand provided evidence for pathotype exchange in both directions across the Tasman. The second year of pathotype analysis has provided more detail on the evolution of rust pathotypes within New
Zealand. From these results a fuller picture of the pathotype diversity of New Zealand cereal rusts is emerging with important consequences for the cereal industry in both New Zealand and Australia.

Before March 2020, many people saw pandemics as a thing of the past. Then came COVID-19. Scientists still do not know exactly where the virus that caused it — SARS-CoV-2 — came from, but it soon reached almost every country worldwide. Over 2 years, the virus has evolved, producing several variants. In this Special Feature, we look at the evolution of SARS-CoV-2 and ask what lessons scientists have learned.

• Two glasses of some wines contain more than the recommended daily limit of sugar and more calories than a hamburger.
• However, alcohol is exempt from food and drink labeling rules, so consumers are mostly unaware of calorie and sugar loads.
• Health experts are pushing for clear nutritional labeling on alcoholic products to help reduce sugar and alcohol consumption.
The Alcohol Health Alliance UK (AHA), representing over 60 health organizations, recently commissioned an independent laboratory to test 30 bottles of red, rose, white, sparkling, and fruit wines sold in the United Kingdom for sugar content.
The resulting analysis, which appears on the AHA’s website, revealed a “wide variation of sugar and calories between products.”

Is Corona Virus a Bio Weapon?
The Internet was brimming with conspiracies about the coronavirus, and, perhaps, one of the most prominent ones was that the virus could be a bioweapon.
According to an ET Prime report, a group of Chinese scientists in Canada were accused of spying and were stripped of their access to Canada’s National Microbiology Lab (NML) which is known to work on some of the most deadly pathogens.The alleged ‘policy breach’, highlighted the bioweapon program of other countries including China. Dr Francis Boyle, the creator of Bio Weapons Act, also claims that ‘the coronavirus is an offensive biological warfare weapon with DNA-genetic engineering’.Again, the claims about coronavirus being a biological weapon are unsubstantiated.
Novel Coronavirus thought to have transferred to Human from the seafood market in Wuhan, China become a one of the most dangerous viruses in the subfamily Orthocoronavirinae. According to the literature, the genome size of RNA of this viruses are greater than 20 kilobases.
Genetic engineers has committed to change the genes of some organisms to create new features of them, and this can be applied for the Coronavirus as well.
Deadly H5N1 birdflu needs just five mutations to spread easily in peopleHarm Kiezebrink
Reference: Phys.org. 15 Apr 2014. Dutch researchers have found that the virus needs only five favorable gene mutations to become transmissible through coughing or sneezing, like regular flu viruses.
World health officials have long feared that the H5N1 virus will someday evolve a knack for airborne transmission, setting off a devastating pandemic. While the new study suggests the mutations needed are relatively few, it remains unclear whether they're likely to happen outside the laboratory.
While discoveries about viruses, which carry the largest genetic information code in nature, have continued unabated for more than a century, viruses are constantly affecting the global biological balance. The main characteristics that make viruses important in this balance include epidemics and mass deaths, the risks of being used as biological weapons, and the continued lack of an effective vaccine or specific treatment for many viruses. However, viruses also offer incredible opportunities for the scientific world, due to biotechnological innovations that have gained momentum in recent years. The detection of viruses is of urgent importance for the early detection of pandemics and epidemics. In this chapter, we discuss the classification of viruses, the effects of viruses on biological balance of our planet, the importance of detecting viruses that have the potential to be used as biological weapons or that carry epidemic or pandemic risks, and the characteristics of such viruses.

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.
Most people who fall sick with COVID-19 will experience mild to moderate symptoms and recover without special treatment.
HOW IT SPREADS
The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or exhales. These droplets are too heavy to hang in the air, and quickly fall on floors or surfaces.
You can be infected by breathing in the virus if you are within close proximity of someone who has COVID-19, or by touching a contaminated surface and then your eyes, nose or mouth.

Scientists have found evidence for mutations in some
strains of the coronavirus that suggest the pathogen may
be adaptingto humans after spilling over from bats.
The analysis of more than 5,300 coronavirus genomes
from 62 countriesshows that while the virus is fairly
stable, some have gained mutations, includingtwo
genetic changes that alter the critical “spike protein”the
virus uses to infect human cells.
UP NEXT
Researchers at the London School of Hygiene and
Tropical Medicine stress that it is unclearhow the
3. against this spike protein because it seems a very good
target. We need to keep an eye on it and make sure that
any mutations don’t invalidate any of these
approaches.”
Studies of the virus revealed early on that the shape of
its spike protein allowed it to bind to human cells more
efficiently than Sars, a related virus that sparked an
outbreakin 2002. The difference may have helped the
latest coronavirus infect more peopleand spread rapidly
around the world.
Scientists will be concerned if more extensive
mutations in the spike protein arise, not only because
they may alter how the virus behaves. The spike protein
is the main target of leading vaccines around the world,
and if it changes too much those vaccines may no
longer work. Other potential therapies, such as synthetic
antibodiesthat home in on the spike protein, could be
less effective, too.
“This is an early warning,” Hibberd said. “Even if these
mutations are not important for vaccines, other
mutations might be and we need to maintain our
surveillance so we are not caught out by deployinga
vaccine that only works against some strains.”
The scientists analysed 5,349 coronavirus genomes that
have been uploadedto two major genetics databases
since the outbreakbegan. By studying the genetic
makeup of the viruses, the scientists worked out how it
4. has diversified into different strains and looked for
signs that it was adaptingto its human host.
In an unpublishedstudy that has yet to be peer
reviewed, the researchers identified two broad groups of
coronavirus that have now spread globally. Of the two
spike mutations, one was found in 788 viruses around
the world, with the other present in only 32.
The study shows that, until January, one group of
coronaviruses in China escaped detection becausethey
had a mutation in the genetic region that early tests
relied on. More recent tests detect all of the known
types of the virus.
Last month, an international team of scientists used
genetic analyses to show that the coronavirus likely
originated in bats and was not made in a lab as some
conspiracy theorists have claimed.
