Low-cost imaging system detects natural gas leaks in real time
Researchers have developed an infrared imaging system that could one day offer low-cost, real-time detection of methane gas leaks in pipelines and at oil and gas facilities. Leaks of methane, the primary component of natural gas, can be costly and dangerous while also contributing to climate change as a greenhouse gas. Infrared device enables reliable monitoring under a range of environmental conditions.

Malaria superbugs pose threat to global malaria control
A lineage of multidrug resistant P. falciparum malaria superbugs has widely spread and is now established in parts of Thailand, Laos and Cambodia, causing high treatment failure rates for the main falciparum malaria medicines, artemisinin combination therapies (ACTs). The emergence and spread of artemisinin drug resistant P falciparum lineage represents a serious threat to global malaria control and eradication efforts.

Global partnership to prevent epidemics with new vaccines launched
A global coalition to create new vaccines for emerging infectious diseases, designed to help give the world an insurance policy against epidemics, launches today at the World Economic Forum in Davos, Switzerland.
With an initial investment of $460 million from the governments of Germany, Japan, and Norway, plus the Bill & Melinda Gates Foundation and the Wellcome Trust, CEPI - the Coalition for Epidemic Preparedness Innovations will seek to outsmart epidemics by developing safe and effective vaccines against known infectious disease threats that could be deployed rapidly to contain outbreaks, before they become global health emergencies.

Cocktail of bacteria-killing viruses prevents cholera infection in animal models
Oral administration of viruses that specifically target cholera bacteria prevents infection and cholera-like symptoms in animal model experiments. The findings are the first to demonstrate the potential efficacy of bacteria-killing viruses—known as bacteriophages, or phages—as an orally administered preventive therapy against an acute gastrointestinal bacterial disease.

What caused the Flint water crisis
Flint, Michigan, continues to grapple with the public health crisis that unfolded as lead levels in its tap water spiked to alarming levels. Now the scientists who helped uncover the crisis have tested galvanized iron pipes extracted from the “ground zero” house. They confirm that the lead that had accumulated on the interior surface of the pipes was the most likely source of the lead contamination.

New material helps fight against hospital-acquired infections
Researchers have developed a new light-activated antimicrobial material for use in the fight against the most common hospital infections. Specifically, the new material is a molybdenum complex that has never been used before in antimicrobial photodynamic therapy (PDT).

Nevada woman killed by superbug resistant to every known antibiotic
A 70-yer old woman in Nevada has died after a superbug which infected her proved resistant to every available type of antibiotic. The woman was already infected in India, where she had an extended stay, and was hospitalized there several times. She returned to Nevada in August 2016. She was admitted to a hospital shortly after her return, but died a month later after treatment with twenty-six different antibiotics was futile.

New framework needed for estimating the social cost of carbon: Report
To estimate the social cost of carbon dioxide for use in regulatory impact analyses, the federal government should use a new framework that would strengthen the scientific basis, provide greater transparency, and improve characterization of the uncertainties of the estimates, says a new report by the National Academies of Sciences. The report also identifies a number of near- and longer-term improvements that should be made for calculating the social cost of carbon.

St. Jude's cardiac devices vulnerable to hacking: FDA
The FDA confirmed that St. Jude Medical’s implantable cardiac devices are vulnerable to hacking. Once hackers gain access to the device, they could deplete the battery or administer incorrect pacing or shocks. The devices — pacemakers and defibrillators — are used in heart patients.

Whitefly: a formidable threat to food security
Researchers have sequenced the genome of the whitefly (Bemisia tabici), an invasive insect responsible for spreading plant viruses worldwide, causing billions of dollars in crop losses each year. The genome study offers many clues to the insect’s remarkable ability to resist pesticides, transmit more than 300 plant viruses, and to feed on at least 1,000 different plant species.

Health wearable devices pose new consumer and privacy risks
Watches, fitness bands, and so-called “smart” clothing, linked to apps and mobile devices, are part of a growing “connected-health” system in the U.S., promising to provide people with more efficient ways to manage their own health. These personal health wearable devices, which are used to monitor heart rates, sleep patterns, calories, and even stress levels, raise new privacy and security risks, according to a new report.

$19 million to develop drugs to treat victims of chemical weapons attacks
First used by the German military against Allied troops in the First World War and in subsequent wars including the Iran-Iraq conflict during the 1980s, chemical weapons were more recently used by the Assad regime in Syria and by ISIS in Iraq and Syria. The National Institutes of Health (NIH) has awarded Rutgers University a five-year grant for more than $19 million for research that would lead to the development of drugs to treat toxicity from chemical agents used in a terrorist attack.

Symptomless Ebola – questions need to be answered before the next outbreak
Scientists know that Ebola can cause anything from severe hemorrhagic fever to no symptoms at all (asymptomatic infections). What wasn’t known, until now, is the number of people who experienced asymptomatic infections during the 2013-2016 outbreak of Ebola in West Africa. While the new report of asymptomatic cases of Ebola virus infection is not unique, it does raise important questions that need to be answered. Over the last couple of years, governments and global public health agencies have increased resources to tackle these questions. Hopefully, we will be better equipped and prepared for the next outbreak.

Supercomputer simulations help develop new approach to tackle antibiotic resistance
Supercomputer simulations at the Department of Energy’s Oak Ridge National Laboratory have played a key role in discovering a new class of drug candidates that hold promise to combat antibiotic resistance. Researchers combined lab experiments with supercomputer modeling to identify molecules that boost antibiotics’ effect on disease-causing bacteria.

Changes required to fortify U.S. blood system against financial, biological threats
The U.S. blood system collects, tests, processes, and distributes the blood that is ultimately used in clinical practice. In 2013, more than 14 million units of blood were collected in the United States from about 15.2 million individuals, with 13.2 million units transfused. Medical advances have reduced the demand for blood in the United States, creating financial pressure on the nation’s blood collection centers and threatening their future survival.

Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
