Excessive outdoor lighting is deadly to animals and takes a toll on human health and wellbeing, too. But when it comes to large-scale environmental problems, this one may be a relatively easy fix.

Here is how oil and heat can form a durable coating.

Rust Belt cities could be the perfect place to develop this renewable energy solution.

Sports are important to young people on many levels. When participating, they experience teamwork, self-discipline, following rules, and just plain fun. Often, children see role models in professional athletes. But professional sports can provide an introduction to history, depicting the times in which they are played. Also like the world we live in, games have evolved over time to respond to events and social changes.

Warfare and military are an integral part of much of ancient and medieval fantasy. This is no surprise: warfare was a key element in development of society and of history, and much of mythology is also about it. As such, it is difficult for fantasy writers and readers alike to avoid war and military matters in general. And if you are going to do something, try to do it well. Army does not spring from the ground like the spartoi of Jason.

Environment and Geography

Environmental conditions include terrain, climate and resources. All three influence how an army will fight and which weapons it will use.

Terrain can be highly varied, but I will divide it into three categories: mountainous, rolling hills and flat. Mountains and forests – and especially forested mountains – are conductive to infantry warfare. Depending on other conditions (such as society, climate etc.), this can mean either light infantry with focus on ambushes, raiding and guerilla warfare; or heavy infantry, with focus on direct confrontation. Both of these were, at different points, in evidence in Spain and Greece.

Environmental Change and Emerging Diseases 28 October 2020 — 3:00PM TO 4:00PM Anonymous (not verified) 13 October 2020 Online

Understanding how environmental changes are directly and indirectly affecting the emergence and spread of disease has assumed global importance.

There is growing awareness that deforestation and land-use conversion, urbanization, human migration, international commerce, and climate change are having significant impacts on human health, but their impact on increasing infectious disease risks has only become more evident with the coronavirus pandemic.

With climate change, and environmental change more generally, disrupting ecologies, and people interacting with wildlife in new ways, it creates the conditions for new diseases to emerge: a better understanding of the health dimensions of environmental change will be critical to managing pandemic risks in future. 

Our event will examine the relationship between environmental change and disease, how these linkages have manifested in historical outbreaks and in the coronavirus pandemic, and the role of environmental policies in minimizing the risk of future emerging diseases.  What can be done to ensure equitable action? What can we learn from our responses to previous pandemics? And will the growing recognition of the diverse risks arising from climate change motivate more climate action?

This event will launch the Energy, Environment and Resources (EER) Programme’s Environment and Society Discussion Series. This series aims to provide a platform to promote interdisciplinary knowledge sharing and policy dialogue to mitigate and adapt to the impacts that climate change, biodiversity loss and natural resource depletion are having on people and communities globally, and on geopolitics, security and international development.

What's next for environmental peacebuilding? Lessons learned and opportunities from conflict-affected states 17 February 2021 — 3:00PM TO 4:00PM Anonymous (not verified) 8 February 2021 Online

 This event explores lessons and opportunities from conflict-affected states.

In the field of peacebuilding, scholars and policymakers increasingly recognize the importance of environmental restoration, afforestation and infrastructural renewal for creating the sustainable livelihoods necessary for successful peacebuilding efforts.

Featuring academics writing for International Affairs on environmental peacebuilding in Colombia, Yemen and the Sahel, this webinar discusses the policy implications of the turn to environmental peacebuilding.

This event is part of the Chatham House’s Environment and Society Discussion Series in which the Energy Environment and Resources Programme brings together leading academics and policymakers to discuss key issues in environmental policy.

In particular, this event focuses on the role of environmental peacebuilding in creating sustainable livelihoods. From the impact the destruction of infrastructure can have on poverty as a driver of conflict, to the role environmental peacebuilding can play in bringing communities together by creating sustainable shared spaces of employment, the importance of the environmental livelihood creation is difficult to overstate.

Panellists focus on how policymakers can best encourage inclusive and sustainable livelihood creation and on addressing the key challenges such approaches face in the context of environmental peacebuilding efforts.

Iron is an essential micronutrient, and, in the case of bacteria, its availability is commonly a growth-limiting factor. However, correct functioning of cells requires that the labile pool of chelatable “free” iron be tightly regulated. Correct metalation of proteins requiring iron as a cofactor demands that such a readily accessible source of iron exist, but overaccumulation results in an oxidative burden that, if unchecked, would lead to cell death. The toxicity of iron stems from its potential to catalyze formation of reactive oxygen species that, in addition to causing damage to biological molecules, can also lead to the formation of reactive nitrogen species. To avoid iron-mediated oxidative stress, bacteria utilize iron-dependent global regulators to sense the iron status of the cell and regulate the expression of proteins involved in the acquisition, storage, and efflux of iron accordingly. Here, we survey the current understanding of the structure and mechanism of the important members of each of these classes of protein. Diversity in the details of iron homeostasis mechanisms reflect the differing nutritional stresses resulting from the wide variety of ecological niches that bacteria inhabit. However, in this review, we seek to highlight the similarities of iron homeostasis between different bacteria, while acknowledging important variations. In this way, we hope to illustrate how bacteria have evolved common approaches to overcome the dual problems of the insolubility and potential toxicity of iron.

Protein biosynthesis is fundamental to cellular life and requires the efficient functioning of the translational machinery. At the center of this machinery is the ribosome, a ribonucleoprotein complex that depends heavily on Mg2+ for structure. Recent work has indicated that other metal cations can substitute for Mg2+, raising questions about the role different metals may play in the maintenance of the ribosome under oxidative stress conditions. Here, we assess ribosomal integrity following oxidative stress both in vitro and in cells to elucidate details of the interactions between Fe2+ and the ribosome and identify Mn2+ as a factor capable of attenuating oxidant-induced Fe2+-mediated degradation of rRNA. We report that Fe2+ promotes degradation of all rRNA species of the yeast ribosome and that it is bound directly to RNA molecules. Furthermore, we demonstrate that Mn2+ competes with Fe2+ for rRNA-binding sites and that protection of ribosomes from Fe2+-mediated rRNA hydrolysis correlates with the restoration of cell viability. Our data, therefore, suggest a relationship between these two transition metals in controlling ribosome stability under oxidative stress.

The histidine kinase Hik33 plays important roles in mediating cyanobacterial response to divergent types of abiotic stresses including cold, salt, high light (HL), and osmotic stresses. However, how these functions are regulated by Hik33 remains to be addressed. Using a hik33-deficient strain (hik33) of Synechocystis sp. PCC 6803 (Synechocystis) and quantitative proteomics, we found that Hik33 depletion induces differential protein expression highly similar to that induced by divergent types of stresses. This typically includes downregulation of proteins in photosynthesis and carbon assimilation that are necessary for cell propagation, and upregulation of heat shock proteins, chaperons, and proteases that are important for cell survival. This observation indicates that depletion of Hik33 alone mimics divergent types of abiotic stresses, and that Hik33 could be important for preventing abnormal stress response in the normal condition. Moreover, we found the majority of proteins of plasmid origin were significantly upregulated in hik33, though their biological significance remains to be addressed. Together, the systematically characterized Hik33-regulated cyanobacterial proteome, which is largely involved in stress responses, builds the molecular basis for Hik33 as a general regulator of stress responses.

The choice for adjuvant chemotherapy in stage II colorectal cancer (CRC) is controversial as many patients are cured by surgery alone and it is difficult to identify patients with high-risk of recurrence of the disease. There is a need for better stratification of this group of patients. Mass spectrometry imaging could identify patients at risk. We report here the N-glycosylation signatures of the different cell populations in a group of stage II CRC tissue samples. The cancer cells, compared to normal epithelial cells, have increased levels of sialylation and high-mannose glycans, as well as decreased levels of fucosylation and highly branched N-glycans. When looking at the interface between cancer and its microenvironment, it seems that the cancer N-glycosylation signature spreads into the surrounding stroma at the invasive front of the tumor. This finding was more outspoken in patients with a worse outcome within this sample group.

Paramphistomosis, caused by the rumen fluke, Calicophoron daubneyi, is a parasitic infection of ruminant livestock which has seen a rapid rise in prevalence throughout Western Europe in recent years. Following ingestion of metacercariae (parasite cysts) by the mammalian host, newly-excysted juveniles (NEJs) emerge and invade the duodenal submucosa which causes significant pathology in heavy infections. The immature larvae then migrate upwards, along the gastrointestinal tract, and enter the rumen where they mature and begin to produce eggs. Despite their emergence, and sporadic outbreaks of acute disease, we know little about the molecular mechanisms used by C. daubneyi to establish infection, acquire nutrients and to avoid the host immune response. Here, transcriptome analysis of four intra-mammalian life-cycle stages, integrated with secretome analysis of the NEJ and adult parasites (responsible for acute and chronic disease respectively), revealed how the expression and secretion of selected families of virulence factors and immunomodulators are regulated in accordance with fluke development and migration. Our data show that whilst a family of cathepsins B with varying S2 sub-site residues (indicating distinct substrate specificities) are differentially secreted by NEJs and adult flukes, cathepsins L and F are secreted in low abundance by NEJs only. We found that C. daubneyi has an expanded family of aspartic peptidases, which is up-regulated in adult worms, although they are underrepresented in the secretome. The most abundant proteins in adult fluke secretions were helminth defence molecules (HDMs) that likely establish an immune environment permissive to fluke survival and/or neutralise pathogen-associated molecular patterns (PAMPs) such as bacterial lipopolysaccharide in the microbiome-rich rumen. The distinct collection of molecules secreted by C. daubneyi allowed the development of the first coproantigen-based ELISA for paramphistomosis which, importantly, did not recognise antigens from other helminths commonly found as co-infections with rumen fluke.

Hi,

I found that under the Dark Theme of PCB Environment Editor 17.4,

the window background is not all dark, resulting in unclear text display。

As shown in the figure below：

When analyzing multiple sessions simultaneously Verisium Manager crashed and reported below error messages:

# A fatal error has been detected by the Java Runtime Environment:

For more details please refer to the attached log file "hs_err_pid21143.log".

Two approaches were tried to solve this problem but neither has worked.
Method.1:

Setting larger heap size of Java process by "-memlimit" options.For example "vmanager -memlimit 8G".

Method.2:

Enlarging stack memory size limit of the Coverage engine by setting "IMC_NATIVE_STACKSIZE" environment variable to a larger value. For example "setenv IMC_NATIVE_STACKSIZE 1024000"

According to "hs_err_pid*.log" it is almost certain that the memory overflow triggered Java's CrashOnOutOfMemoryError and caused Verisium Manager to crash. There are some arguments about memory management of Java like "Xms, Xmx, ThreadStackSize, Xss5048k etc" and maybe this problem can be fixed by setting these arguments during analysis. However, how exactly does Verisium Manager specify these arguments during analysis? I tried to set them by the form of setting environment variables before analysis but it didn't work in analysis and their values didn't change.

Is there something wrong with my operation or is there a better solution?

Thank you very much.
