About this episode

Integrated pest management describes effective and environmentally sensitive approaches to controlling agricultural pests, which are based on combinations of different practices. Educational information on integrated pest management is much more accessible in the developed world than in developing countries. This is due to a combination of language and technology barriers around information sharing. To ensure that reliable content related to integrated pest management systems and other educational resources can also be widely accessed by people in developing countries, researchers at Michigan State University and Purdue University have created Scientific Animations Without Borders – or SAWBO – which provides scientifically accurate animations about various important topics.

Causality: A Fundamental Necessity or Part of the Problem?

Original Article Reference

This SciPod is a summary of the paper ‘Is Causality a Necessary Tool for Understanding Our Universe, or Is It a Part of the Problem?’, from Entropy. https://doi.org/10.3390/e23070886

 

About this episode

For thousands of years, the notion of a one-way flow of cause-and-effect has underpinned virtually every scientific theory. Yet Dr Martin Tamm at the University of Stockholm argues that this notion of ‘causality’ may be holding back our understanding of how the Universe really works. Through his research, he suggests an alternative approach, based around a mathematical construct named ‘probability space’. His ideas could ultimately lead to new solutions to problems that physicists have struggled with for decades.

Strategies and Tools for Studying Microglial-Mediated Synapse Elimination and Refinement

Original Article Reference

This SciPod is a summary of the paper  ‘Strategies and Tools for Studying Microglial-Mediated Synapse Elimination and Refinement’

Authored by ‘Raffaella Morini, Matteo Bizzotto, Fabio Perrucci, Fabia Filipello and Michela Matteoli’

Published in the open access journal Frontiers in Immunology. https://doi.org/10.3389/fimmu.2021.640937 

About this episode

Synapse elimination is a tightly regulated process, and an aberrant number of synapses both during the early stages of development or later in aging, has been observed in several neurological conditions, including Alzheimer’s disease, schizophrenia or autism. Effective methodological approaches for investigating how supernumerary synapses and apoptotic material are removed from the brain are vital for understanding the underlying mechanisms, and this, in turn, may provide exciting avenues for the development of new treatments. Dr Morini, Dr Filipello and colleagues at Humanitas University and at Washington University in St Louis have recently published a review about the different strategies and tools available to study the role of microglia, the phagocytes of the brain, in neuronal and synaptic substrates phagocytosis.

About this episode

Hundreds of millions of years after the Big Bang, charged, ‘ionised’ particles not seen since the earliest ages of the universe began to re-emerge. Named ‘reionisation’, this event was crucially important in the history of our universe – but because it occurred so far back in the past, telescope observations can only offer astronomers limited clues about how it unfolded. In his research, Dr Nick Gnedin at the Fermi National Accelerator Laboratory uses advanced computer simulations to study reionisation. His team’s project, named ‘Cosmic Reionization On Computers’, or CROC, now offers a key resource to researchers studying this distant period.

About this episode

Enshrouding the Martian surface with thick clouds of dust, the Red Planet’s unique global dust storms have long mystified astronomers and planetary scientists. James Shirley, at NASA’s Jet Propulsion Laboratory, has shown through his research that the occurrence of these global storms is strongly linked to the changes in Mars’ motion about the gravitational centre of the solar system. Already boasting strong observational evidence, his results could not only improve our understanding of the Mars atmosphere – they may also lead to a better understanding of turbulent weather patterns on Earth.

About this episode

Despite advances in agricultural science, communicating best practices to farmers in remote areas remains difficult. Although mobile learning tools, such as animated videos, have the potential to effectively present new information to diverse, isolated audiences, their long-term efficacy is poorly understood. A team of researchers from the Agricultural Research Institute of Mozambique, Michigan State University and Iowa State University followed up with farmers in Mozambique two years after receiving video-based, mobile instruction. Their findings suggest these methods are just as successful as in-person teaching styles in improving farmers’ ability to retain and use new information.

About this episode

Dietary antioxidants, such as vitamin C, are known to reduce the negative effects of toxins in mammals by preventing cellular damage caused by reactive oxygen species. However, it is not known whether these antioxidants have a similar protective effect in insects. A team led by Dr Barry Pittendrigh at Purdue University have investigated the adaptive responses of fruit flies to insecticide exposure in the presence of vitamin C. Their work has exciting implications for reducing the threat of insecticide resistance in insect pests.

Identifying an Achilles’ Heel in Insecticide Resistance – Dr Barry Pittendrigh, Purdue University

Original Article Reference

This SciPod is a summary of the paper ‘The insulin signalling pathway in Drosophila melanogaster. A nexus revealing an “Achilles’ heel” in DDT resistance’, published in Pesticide Biochemistry and Physiology. doi.org/10.1016/j.pestbp.2020.104727

About this episode

Insecticide resistance is an ongoing challenge for agriculture and the control of insect-transmitted diseases. In a recent study at Purdue University, a team of scientists led by Dr Barry Pittendrigh  identified a potential chink in the armour of insecticide resistance in fruit flies. If this Achilles’ heel can be exploited, it bodes well for the future control of destructive insects.

Neurodevelopmental Disorders Arising From Histone Methylation Malfunctions – Dr Shigeki Iwase, University Of Michigan

About this episode

Neurodevelopmental disorders range from those on the relatively common autism spectrum to much rarer disorders such as KDM5C-disorder and Weidemann-Steiner Syndrome. Exciting advancements in human genetics have shown that histones – the proteins our DNA wraps around – play a vital role in healthy brain development. Dr Shigeki Iwase from the University of Michigan studies how mutations in the enzymes that regulate histone structure and function can cause cognitive disorders. His work has led to important new discoveries, including how counterpart enzymes can be utilised for therapies.

‘Neonicotinoid-containing insecticide disruption of growth, locomotion, and fertility in Caenorhabditis elegans’ from PLOS One https://doi.org/10.1371/journal.pone.0238637

About this episode

Conventional agricultural practices have greatly increased the yield and efficiency of modern farming, allowing us to better feed a growing population. To protect crops from pests and disease, we rely heavily on chemical pesticides. However, the impacts of pesticide use are not localised to plants – there is growing awareness that pesticides can negatively affect many other organisms, including humans. Professor Kathleen Susman of Vassar College in New York, along with her colleagues, assessed whether a commonly used class of pesticides, neonicotinoids, have the potential to cause damaging effects in non-target organisms. Her findings also have implications for human health.

About this episode

Many fields of experimental research are now facing a daunting challenge: despite the fact that separate research teams may work on the same system, the end results of their experiments can be widely varied. In his research, Dr Stanley Luck, at the Science, Technology and Research Institute of Delaware, explores the reasons behind this inherent inability to reproduce experimental results. Based on his analysis, he now suggests two key requirements that must be met to overcome this crisis, which could have a profound influence over the techniques employed by experimental researchers in the future.

Illuminating New Insights Into Lightning Initiation Through Interferometry -Dr Xuan – Min Shao, Los Alamos National Laboratory

About this episode

Radio frequency inteferometric lightning maps are important tools for researchers exploring the electrical processes that unfold within storm clouds. Dr Xuan-Min Shao and colleagues at Los Alamos National Laboratory in New Mexico, who first introduced broadband interferometry to lightning research over two decades ago, have now developed an advanced ‘beam steering’ interferometry technique to significantly improve the accuracy of lightning mapping. This approach, together with their recently developed polarisation detection technique, has begun to reveal new physics involved in lightning discharges. Their recent work shows how lightning initiation, which has been poorly understood until now, may be linked to high-energy cosmic particles entering Earth’s atmosphere.

Herbivore Helpers Using Livestock To Manage Rangelands – Dr John Walker, Texas A&M University

About this episode

Domestic herbivores – such as cattle, sheep, and goats – are remarkably important to ecosystems. Their feeding behaviours aid the management of natural habitats by preventing any individual plant species dominating the landscape. Thus, understanding livestock dietary preferences is vital for informing land management decisions. Dr John Walker from the Texas A&M AgriLife Research and Extension Center has devoted his career to exploring livestock dietary preferences, and how they can be manipulated to benefit rangelands. His ‘Aggie Cedar Eater’ (ACE) goats are now helping to control invasive juniper shrubs across the Great Plains of the US.

Glycomimetic Peptides As Immune System Activators In The Treatment Of Cancer And Viral Infections – Susavion Biosciences

About this episode

Immune system cells express a number of receptors that bind to sugar ligands. This binding initiates the activation of T-cell lymphocytes and natural killer cells. Dr J. Kenneth HooberDr Laura L. Eggink and the team at Susavion have designed peptides that bind to different receptors on immune cells. The peptides effectively extend the lives of mice with glioblastoma and ovarian cancer, and prevent the replication of viruses in the presence of non-neutralising antibodies. The mechanism of action of their peptides could inspire the development of effective treatments for Covid-19 and other viral infections.
