Hank introduces us to biogeochemical cycles by describing his two favorites: carbon and water. The hydrologic cycle describes how water moves on, above, and below the surface of the Earth, driven by energy supplied by the sun and wind. The carbon cycle does the same... for carbon!

Using infectious diseases sensitive to climate as indicators of climate change helps stimulate and inform public health responses
Chikungunya virus (CHIKV) is currently one of the most relevant arboviruses to public health. It is a member of the Togaviridae family and alphavirus genus and causes an arthritogenic disease known as chikungunya fever (CHIKF). It is characterized by a multifaceted disease, which is distinguished fr...om other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

In April 2020, Gavi and COVAX joined the Access to COVID-19 Tools Accelerator (ACT-A) to provide equitable global access to COVID-19 vaccines to tackle the pandemic. In June 2020, the Gavi COVAX Advance Market Commitment (AMC) was launched to finance equitable access in 92 lower-income countries. Si...nce then, US$ 10 billion has been raised for the AMC to procure vaccines and support delivery. Despite a challenging supply situation, COVAX has now shipped one billion doses to 144 countries, including over 870 million to AMC economies.

The SAARC Member States have more than an estimated 2.0 million TB cases accounting for close to one-third of the total cases of TB in the world. India alone had almost one-fifth of the global disease burden due to TB. India, Pakistan and Bangladesh followed by Afghanistan are the major contributors... of disease burden of TB in the SAARC Region. They are countries that have a dubious distinction of being on the list of 22 TB High Disease Countries in the world.

Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we re...port an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.

It is of utmost importance to low-income countries and some lower-middle income nations in the time of the SDG period that they are not on course to accomplish the health-related SDG 3 and its targets until 2030. If we honestly intend to support this goal and realize it for the people living in the ...regions that are facing the lowest survival chances, we also need to recognize that these countries are far from being in a position to raise the necessary resources solely with their own means.

Gaps in data covering refugees, asylum seekers, migrants and internally displaced populations are endangering the lives and wellbeing of millions of children on the move, warned five UN and partner agencies today. In 'A call to action: Protecting children on the move starts with better data', UNICEF..., UNHCR, IOM, Eurostat and OECD together show how crucial data are to understanding the patterns of global migration and developing policies to support vulnerable groups like children.

Climate change is a growing concern for Bangladesh because 90 percent of the country is approximately 10 feet above sea level. An evaluation was completed which discovered that high tides in Bangladesh were increasing 10 times more rapidly than the global average. This predicted rapid increase in se...a levels places Bangladesh four times higher than the global average. By 2050, approximately 20 percent of the inhabited land in Bangladesh will be inundated by the sea resulting in displacement for nearly 20 million people. The Government of Bangladesh has implemented policies and plans to focus on climate change concerns, but there is still much work to be completed.
Bangladesh is a nation which will continue to experience the devastating effects of climate change. These concerns for the nation are recognized and the Government of Bangladesh is working progressively to implement mitigation and preparedness measures along with making national economic and transportation improvements to better sever and protect the people of Bangladesh.

This article analyzes the impact of the COVID-19 pandemic on foreign aid. Using examples from Canadian foreign aid, it argues that, despite the terrible toll it is exacting, the crisis has accelerated some significant positive pre-existing trends, both by destabilizing the perception of aid as flowi...ng essentially from the Global North to Global South and by reinforcing awareness of the importance of joint efforts for global public goods and humanitarian assistance, as well as debt relief. However, it has also reinforced potentially harmful self-interested justifications for aid, which could align assistance more with donors’ priorities than the needs of the poor

Scientists have known for more than half a century that patients could develop resistance to the drugs used to treat them. Alexander Fleming, who is credited with creating the first antibiotic, penicillin, in 1928, cautioned of the impending crisis while accepting his Nobel prize in 1945: “There ...is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant.” Since then antibiotics have proved one of the most effective interventions in human medicine. Sadly, the overuse and misuse of this precious resource have brought us to a global crisis of antimicrobial resistance (AMR). To address this crisis nearly seven decades after Fleming’s lecture the first UN general assembly meeting on drug resistance bacteria was convened in September 2017.
