Soil’s carbon storage could help limit impact of climate change
Soils currently lock away around 2.4 trillion tons of greenhouse gases, which are stored underground as stable organic matter. Researchers say the world’s soils could store an extra eight billion tons of greenhouse gases, helping to limit the impacts of climate change. Growing crops with deeper root systems, using charcoal-based composts, and applying sustainable agriculture practices could help soils retain the equivalent of around four-fifths of annual emissions released by the burning of fossils fuels, the researchers say.

Oil, gas wastewater disposal pollutes surface water, harm waterways
Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or “fracking,” to release natural gas and oil from underground rock. This process results in in water pollution which may increase endocrine disrupting chemicals (EDCs) in surface and ground water, exposing populations living near these operations to increased risk of disease. High levels of EDC activity were found in the surface water near a hydraulic fracturing wastewater disposal facility in West Virginia. Approximately 36,000 of these disposal wells are currently in operation across the United States.

Paper-based test to help prevent food poisoning
The foodborne bacteria Salmonella alone led to nearly 20,000 hospitalizations and almost 400 deaths in 2013. Economists estimate that the treatment of all these patients and the related productivity losses cost more than $3 billion annually. And those numbers account for just one of the fifteen pathogens responsible for most of the food poisoning cases. Scientists have developed a simple, paper-based test that could help detect pathogens hitchhiking on food before they reach store shelves, restaurants and, most importantly, our stomachs.

2010 Maryland food poisoning outbreak traced to Asian strain of seafood pathogen
V. parahaemolyticusis the most important cause of seafood poisoning in the United States. Approximately 4,500 cases occur annually in the United States, according to the Center for Disease Control and Prevention. The number of cases has risen in recent years, possibly do to the warming climate.

Starvation is only one crop breeding cycle away
Global population growth, urbanization, and a changing climate mean staple food crops will need to achieve much higher yields in the near future. New research proposes genetic engineering solutions to improve photosynthetic efficiency of food crops, boosting yield under higher temperatures and carbon dioxide levels. Because it can take twenty to thirty years of breeding and product development efforts before new crops are available to farmers, those efforts must start now.

Efficient alternative for Ebola screening program for travelers
As of 31 January 2016, a total of 28,639 cases and 11,316 deaths have been attributed to Ebola, figures that are assumed to significantly underestimate the actual scope of the 2014 Ebola Hemorrhagic Fever outbreak in West Africa. In the United States, there were also two imported cases and two locally acquired cases reported in September-October 2014. Researchers offer an alternative policy for Ebola entry screening at airports in the United States. “Security measures implemented after 9/11 taught us a lot about what not to do,” one of the researchers say. “We learned that finding the one person who intends to do harm out of several million passengers is akin to finding a needle in a haystack.”

Ebola no longer a “Public Health Emergency of International Concern”: WHO
On Tuesday the WHO officials met to consider the Ebola virus disease (EVD) outbreak in West Africa, and to decide whether the event continues to constitute a Public Health Emergency of International Concern (PHEIC) and whether the current Temporary Recommendations should be extended, rescinded, or revised. WHOconcluded that Ebola transmission in West Africa no longer constitutes an extraordinary event, that the risk of international spread is now low, and that countries currently have the capacity to respond rapidly to new virus emergences. Accordingly, the Ebola situation in West Africa no longer constitutes a Public Health Emergency of International Concern, and the temporary recommendations adopted in response should now be terminated.

Plum Island may be turned into a national park rather than sold to developers
Members of the New York and Connecticut congressional delegations announced on Friday a plan to launch a study of Plum Island’s natural and historic resources, saying the plan is one step toward halting the sale of the island to developers. In 2009 DHS said the island would be sold to developers to help fund the new BioLab Level 4 on the campus of Kansas State University, which is set to open in 2022.

Protecting soldiers from emerging infectious diseases
Emerging infectious diseases that the U.S. military could encounter around the globe, particularly those found in tropical settings such as dengue, Burkholderia melioidosis, and malaria, are often difficult to distinguish by their clinical characteristics alone. Scientists from the Naval Health Research Center (NHRC) and the Defense Threat Reduction Agency (DTRA) held a two-day meeting earlier this month to discuss progress and goals for a joint biosurveillance project which aims to develop novel point of need (PON) diagnostics to identify pathogens that cause acute febrile illnesses and threaten global and public health.

New biotechnology improves crop performance
With the world’s population exploding to well over seven billion, feeding the human race is getting even more challenging. Increasing the yield from crops such as wheat, maize, rice and barley, is paramount to growing enough food. In addition, crop production is now affected by stressors such as drought, climate change, and the salinization of fields — presenting obstacles to our future food supply. Rsearchers have discovered a way to enhance a plant’s tolerance to stress, which in turn improves how it uses water and nutrients from the soil. These improvements increase plant biomass and yield.

Expanding use of recycled water would benefit the environment, human health
More than 1 in 9 people around the world, about 750 million, do not have access to safe, clean drinking water, and the problem is expected to worsen in step with rising greenhouse gas concentrations, population increases and climate change. Researchers found that found that recycled water has great potential for more efficient use in urban settings and to improve the overall resiliency of the water supply.

Better tracking of police homicides
Official counts of homicides by police seriously undercount incidents, according to a study, but a relatively new national data system, currently in use in thirty-two states, could be a crucial tool for gathering more comprehensive information, say the researchers.

Conditions increasing Zika virus risk present in many U.S. cities
Key factors that can combine to produce a Zika virus outbreak are expected to be present in a number of U.S. cities during peak summer months. The Aedes aegypti mosquito, which is spreading the virus in much of Latin America and the Caribbean, will likely be increasingly abundant across much of the southern and eastern United States as the weather warms, according to a new study.

Fertilizer applied to fields today will contaminate water for decades
Nitrogen fertilizer applied to farmers’ fields has been contaminating rivers and lakes and leaching into drinking water wells for more than eighty years. Dangerous nitrate levels in drinking water could persist for decades, increasing the risk for blue baby syndrome and other serious health concerns.

We Ran the C.D.C.: Kennedy Is Endangering Every American’s Health
Nine former leaders of the Centers for Disease Control and Prevention (CDC), who served as directors or acting directors under Republican and Democratic administrations, serving under presidents from Jimmy Carter to Donald Trrump, argue that HHS Secretary Roert F. Kennedy Jr. poses a clear and present danger to the health of Americans. He has placed anti-vaxxers and conspiracy theorists at top HHS positions, and he appears to be guided by a hostility to science and a belief in bizarre, unscientific approaches to public health.
