A new threat to bees? Entomopathogenic nematodes used in biological pest control cause rapid mortality in Bombus terrestris - Dutka &al (2015) - PeerJ

A new threat to bees? Entomopathogenic nematodes used in biological pest control cause rapid mortality in Bombus terrestris - Dutka &al (2015) - PeerJ | Complex Insight  - Understanding our world | Scoop.it

There is currently a great deal of concern about population declines in pollinating insects. Many potential threats have been identified which may adversely affect the behaviour and health of both honey bees and bumble bees: these include pesticide exposure, and parasites and pathogens.

 

Whether biological pest control agents adversely affect bees has been much less well studied: it is generally assumed that biological agents are safer for wildlife than chemical pesticides. The aim of this study was to test whether... nematodes sold as biological pest control products could potentially have adverse effects on the bumble bee... One product was a broad spectrum pest control agent... the other product was specifically for weevil control...

 

Both nematode products caused ≥80% mortality within the 96 h test period when bees were exposed to soil containing... nematodes at the recommended field concentration... Of particular concern is the fact that nematodes from the broad spectrum product could proliferate in the carcasses of dead bees, and therefore potentially infect a whole bee colony or spread to the wider environment.

Scope and Opportunities of Bioengineering and Biotechnology in Agriculture and Related Industries - APO (2015)

Scope and Opportunities of Bioengineering and Biotechnology in Agriculture and Related Industries - APO (2015) | Complex Insight  - Understanding our world | Scoop.it

p. 305-313: With Asia having some of the fastest-growing economies with over 60% of the world’s population, 34% of the world’s arable land, and 36% of the world’s water resources, the region’s need to overcome formidable challenges and improve its total agricultural production and agricultural productivity are urgent... 

 

Feeding and nourishing a larger, more urban, and increasingly affluent Asian population sustainably and equitably will be an unprecedented challenge in the coming years. It will require a more holistic approach to address agricultural production an

d productivity more effectively.

 

Increasing production of food, feed, and fiber through the use of modern biosciences and biotechnology is only one among many strategies needed to meet this challenge. Access to modern science and technology will need to be supported by more comprehensive policies on investment, regulations, and education. In addition, while rural areas currently hold most of the world’s poor and hungry, and will continue to do so for many years to come, the urban areas of Asia will require more attention and distinct focus from national governments... 

 

Increasing productivity is a development imperative, whether urban or rural, if more agricultural production is to be achieved with reduced arable land, labor, and water in Asia. And therein lies the huge potential for biotechnology as a “green” technology.

ComplexInsight's insight:

Having grown up  in a northumberland mining village in the north east of England, surrounded by farming and small woodlands - agriculture is something i think of intimately interwound with industry and how we live. If you grew up in a city - it can seem distant, but its always fundamental. If you grew up around farms - you know they are places of high and low tech. Strains and breeds are early forms of bio-engineering, agricultural equipment gives access to pragmatic engineering principles early on. In the coming decades advanced in bioengineering and biotech will increasingly be larger components of modern agriculture in order to meet increasing population pressures and demands generated by increased urban living. This report clearly helps identify the opportunities and possibilities and policy requirements that exist. If you are tracking the technology aspects of modern agriculture or interested in how agriculture will ahve to change to address increasing social needs - this report is well worth reading.

"Scientists have made an amplifier to boost biological signals, using DNA and harmless E. coli bacteria.

Conventional amplifiers, such as those that are combined with loudspeakers to boost the volume of electric guitars and other instruments, are used to increase the amplitude of electrical signals.
Now scientists from Imperial College London have used the same engineering principles to create a biological amplifier, by re-coding the DNA in the harmless gut bacteria Escherichia coli bacteria (E. coli). 

The team say this ‘bio-amplifier’ might be used in microscopic cellular sensors , which scientists have already developed, that could detect minute traces of chemicals and toxins, to make them more sensitive. Ultimately, this could lead to new types of sensors to detect harmful toxins or diseases in our bodies and in the environment before they do any damage.
In laboratory tests, the team’s bio-amplifier was able to significantly boost the detection limit and sensitivity of a sensor designed to detect the toxin arsenic. The device is also modular, which means that the devices can be easily introduced in different genetic networks, and can potentially be used to increase the sensitivity and accuracy of a broad range of other genetic sensors to detect pathogens and toxins.
The results of the study are published in the journal Nucleic Acids Research. 
Dr Baojun Wang, who is now based at the University of Edinburgh, but carried out the study while in the Division of Cell and Molecular Biology at Imperial, said: “One potential use of this technology would be to deploy microscopic sensors equipped with our bio-amplifier component into a water network. Swarms of the sensors could then detect harmful or dangerous toxins that might be hazardous to our health. The bio-amplifiers in the sensors enable us to detect even minute amounts of dangerous toxins, which would be of huge benefit to water quality controllers.”
Scientists have previously known that cells have their own inbuilt amplifiers to first detect and then boost biological signals, which are crucial for survival and reproduction. They have been attempting to understand how they work in more detail so as to remodel them for other applications. However the challenge for scientists has been engineering a device that can predictably amplify signals without distortion or feedback.
In the study, scientists first re-engineered genes involved in a special cell network called hrp (hypersensitive response and pathogenicity), which have naturally occurring amplifying proteins that function just like an electronic amplifier. They then cloned these amplifying components and inserted them into the harmless gut bacteria E. coli, fitting it with a synthetic arsenic input sensor and a fluorescent green protein gene as the output.  ..."

Bacteria 'have lessons for economy'

Bacteria 'have lessons for economy' | Complex Insight  - Understanding our world | Scoop.it
Colonies of bacteria balance growth against risk, just like financial investors, ecologists have found.
ComplexInsight's insight:

Almost half a century ago Richard Levins first suggested that trade-offs in organisms' investment decisions lead to them exploiting different niches, and this concept may apply both in biological ecology and in financial markets, but it has not previously been demonstrated as clearly by experimental observations. Using lab-based synthetic biology, experiments in bacterial evolution, and mathematical modelling a new study test Levins hypothesis and  finds links between behavioural patterns of micro-organisms and markets.  A research group from the UK and Australia used strains of the bacterium E. coli that were constrained in the amount of resource that they had for growth, but that were also subjected to varying degrees of biological stress. The work is described in a paper in the journal Ecology Letters and covered by the BBC Science team.

Gene therapy trial 'cures children'

Gene therapy trial 'cures children' | Complex Insight  - Understanding our world | Scoop.it
A disease which robs children of the ability to walk and talk has been cured by pioneering gene therapy to correct errors in their DNA, say doctors.
ComplexInsight's insight:

After the initial hype around gene therapy, fast solutions failed to meet expectations.  Following a death in one trial and other patients developed leukaemia  studies showed that  introducing new and modified genes could activate cancer genes. Since then safety concerns have been high. The first gene therapy trials in europe were not approved until 2012.  The BBC article describes a new technique developed at the San Raffaele Scientific Institute in Milan, Italy  for children born with metachromatic leukodystrophy.  Babies born with metachromatic leukodystrophy appear healthy, but their development starts to reverse between the ages of one and two as part of their brain is destroyed. Three children  with the disease underwent the treatment and have so far showed normal development with  no side effects. While the patients will continue to be followed, the treatment shows that some of the potential promises of gene therapy may come true.

Changing gut bacteria through diet affects brain function, UCLA study shows

Changing gut bacteria through diet affects brain function, UCLA study shows | Complex Insight  - Understanding our world | Scoop.it

UCLA researchers now have the first evidence that bacteria ingested in food can affect brain function in humans. In an early proof-of-concept study of healthy women, they found that women who regularly consumed beneficial bacteria known as probiotics through yogurt showed altered brain function, both while in a resting state and in response to an emotion-recognition task.

ComplexInsight's insight:

Gut instinct and trust your gut are expressions we use often - researchers at UCLA have now shown there is more to it that simply vernacular expression. Understanding the role of bacteria and human health ecology is becoming far more important to human health than our initial approach of bombing them with anti-biotics first suggested. The new study from UCLA has implications for use of anti-biotics with neonatal care, diet and development and potentially areas such as depression. Much more research following these initial findings will be needed but we are only just starting to discover just how complex we actually are.

Can CRISPR Avoid the Monsanto Problem?

Can CRISPR Avoid the Monsanto Problem? | Complex Insight  - Understanding our world | Scoop.it

It is distressing, but a fact, that the more rapidly any technology is adopted by scientists the more likely it is to leave people confused, anxious, and suspicious. This week, I wrote an article for the magazine about just such a revolutionary technique, called CRISPR, that permits scientists to edit the DNA of plants and animals with an ease and a precision that even a decade ago seemed inconceivable.

CRISPR research has already begun to transform molecular biology. There have been bold new claims about its promise and powers nearly every day. Yet, for the past fifty years, at least since Watson and Crick demonstrated that DNA contained the blueprints required to build everything alive, modern science has been caught in a hype trap. After all, if we possess such exquisitely detailed instructions, shouldn’t they be able to help us fix the broken genes that cause so many of our diseases?

The assumption has long been that the answer is yes. And for decades, we have been told (by the medical establishment, by pharmaceutical companies, and, sadly, by the press) that our knowledge of genetics will soon help us solve nearly every malady, whether it affects humans, other animals, or plants.

It turns out, however, that genetics and magic are two different things. Deciphering the blueprints in the three billion pairs of chemical letters which make up the human genome has been even more complex than anyone had imagined. And even though the advances have been real, and often dramatic, it doesn’t always seem that way. This has led many people to discount, and even fear, our most promising technologies. Somehow, we take lessons more readily from movies like “Jurassic Park” and “Gattaca” than from the very real, though largely incremental, advances in medical treatments.

This dangerous disconnect between scientific possibility and tangible results has already caused great harm: a scientifically unjustified fear of G.M.O.s, for example, has prevented many potentially life-enhancing crops from even being tested, let alone planted widely. The death of one patient, in 1999, halted all human-gene-therapy experiments in the United States for several years. We should, of course, be exceedingly cautious with such research, but if the U.S. is going to stop studies that could potentially help millions of people there are costs to that, too. (It’s worth remembering that there are real risks to everything we do: aspirin kills hundreds of Americans every year, and in the first half of 2015 nearly twenty thousand people have died in car accidents.)

Because it makes manipulating genes so much easier, CRISPR offers researchers the ability to rapidly accelerate studies of many types of illness, including cancers, autism, and AIDS. It will also make it possible to alter the genes of plants so that they can resist various diseases (without introducing the DNA of a foreign organism, which is how G.M.O.s are made). With CRISPR, almost anything could become possible: You want a unicorn? Just tweak the horse genome. How about a truly blue rose? The gene for the blue pigment does not exist naturally in roses. With CRISPR, it should be a trivial matter simply to edit that gene in.

Eventually, CRISPR should also permit technicians to edit embryos, which, at least in theory, could change the genetic lineage of mankind. The prospect is at least as frightening as it is exciting, and we need to start talking about that now. In the press, at least, that conversation—about perhaps the most exciting advance in the history of molecular biology—seems to have started. Two of the researchers I focussed on in my piece for The New Yorker have also been featured in other publications in the past two weeks: the Times has a profile of Jennifer Doudna, the Berkeley biochemist who helped figure out how to program CRISPR molecules to edit DNA, and STAT, a new online health and science publication launched by the Boston Globe’s owner, has one about Feng Zhang, a pioneering biologist at the Broad Institute of Harvard and M.I.T., who first made the technology work in mammals. The subject will soon get even more attention. Early next month, the National Academy of Sciences will convene an international conference devoted to the ethical use of this powerful new tool.

Artificial vanillin receptor modulates transcription - PLOS Synthetic Biology Community

Artificial vanillin receptor modulates transcription - PLOS Synthetic Biology Community | Complex Insight  - Understanding our world | Scoop.it
Bacteria adjust to different environmental conditions mainly by modulating transcription. Internal and external stimuli affect regulatory elements, all of which formulate the complex transcriptional profile of an organism at any given moment. In synthetic biology, the use of synthetic genetic circuits and metabolic pathways, which are often unresponsive to the aforementioned native regulation, is a common procedure. Such behavior can be advantageous, as it allows the organism to remain unaffected by unpredictable perturbations. In many cases, however, the lack of interaction with the internal control leads to undesired effects: metabolic intermediate accumulation, reduced fitness, and decreased product yields. This sets the framework of a recent research paper from the groups of Stephen Mayo and Richard Murray, where they describe a de novo transcription factor that is regulated by vanillin.

Vanillin is a byproduct of lignin degradation and an important substrate for the flavor industry. It is a phenolic compound with cytotoxic effects. In this article, the researchers modified qacR, a tetR-family repressor to bind vanillin, which binds to DNA via a helix-turn-helix domain. In the absence of the effector molecule, qacR physically inhibits RNA polymerase from transcribing the region downstream the binding site (see figure). The inducer causes conformational changes that prevent this binding, thus activating the gene. The procedure for qacR engineering consists of three steps:

(i) computational protein design. The researchers superimposed vanillin with the qacR crystal structure, enabling them to identify the potential binding conformations and the crucial aminoacids. They subsequently came up with a number of protein mutants that could form the correct interactions with vanillin and did not have steric clashes.

(ii) cell-free initial screening. The proteins resulting from the previous step were tested in an in vitro transcription/translation system. This methodology let the authors of the paper validate the repression qacR imposes on a reporter gene (GFP), while screening the functionality of the engineered proteins. Since all of the initial modified proteins failed to be activated by vanillin, the researchers went back to step (i) and designed more modifications. This time, two mutants showed the desired phenotype.

(iii) in vivo validation. As a last step, the two proteins from step (ii) were tested in E.coli. Both were able to suppress GFP expression in the lack of activator. One of them responded positively to increasing concentrations of vanillin, resulting in increased fluorescence.

Increasing production of food, feed, and fiber through the use of modern biosciences and biotechnology is only one among many strategies needed to meet this challenge. Access to modern science and technology will need to be supported by more comprehensive policies on investment, regulations, and education. In addition, while rural areas currently hold most of the world’s poor and hungry, and will continue to do so for many years to come, the urban areas of Asia will require more attention and distinct focus from national governments... 

 

Increasing productivity is a development imperative, whether urban or rural, if more agricultural production is to be achieved with reduced arable land, labor, and water in Asia. And therein lies the huge potential for biotechnology as a “green” technology.

Human Deaths and Third-Generation Cephalosporin use in Poultry, Europe - Vol. 19 No. 8 - August 2013 - Emerging Infectious Disease journal - CDC | Complex Insight  - Understanding our world | Scoop.it

Globally, antimicrobial drug resistance is rapidly rising, with resultant increased illness and death. In Europe, increasing proportions of bloodstream infections caused by E. coli are resistant to third-generation cephalosporins...

ComplexInsight's insight:

Antibiotic use in agriculture tends to be a tension filled debate.  Farmers  want healthy stock and the use of antibiotics as with people has had a major impact. However use of antiobiotics in farming helps accelerate bacterial evolution and antibiotic resistance. The debate around antibiotic overuse on farms or over perscription in human medicine and the relation to antibiotic-resistant bacteria, how antibiotic resistant strains migrate from farms to elswhere is ongoing. The human and financial impact and cost of antiobiotic overuse  in agriculture has until now been a grey area of discussion.  A multi-national team of researchers recently published their findings to these questions in the open journal Emerging Infectious disease published by CDC. They found  number of avoidable deaths and the costs of health care potentially caused by third-generation cephalosporin use in food animals is a staggering 1,518 deaths and 67,236 days in the hospital, every year, which would not otherwise have occurred. Considering those factors, they recommend the ongoing use of these antimicrobial drugs in mass therapy and prophylaxis should be urgently examined and stopped, particularly in poultry.  The article and technical appendix are worth reading.
