Black licorice. You either love it – or you hate it. But one Western researcher is offering a reason to pass the next time you think about reaching for that black licorice jelly bean, twist or whip – your health.

Cold weather increases the risk of mortality in Texas residents, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) School of Public Health. The findings were recently published in the journal Environmental Pollution.

A new study explains for the first time how nanoparticles like those in diesel exhaust fumes cause heart disease by lodging in inflamed blood vessels, writes Oliver Tickell. The study, published as the UK government is ordered before the High Court to justify its refusal to publish plans to tackle illegal air pollution which afflicts 38 million people, also raises wider fears about 'engineered nanoparticles' in the environment.

Airborne particulates on subway platforms and trains are up to 10 times higher than outside air, around three times higher than levels in Montreal’s Metro

A new study co-authored by U of T Engineering ProfessorGreg Evans shows that subways increase our personal exposure to certain pollutants, even as they decrease overall emissions – and that Toronto has the highest levels in Canada.

A drug created from a malaria protein stopped tumour growth of chemotherapy-resistant bladder cancer, offering hope for cancer patients not responding to standard treatments.

A new study, supported by the Minamata Convention’s Interim Secretariat hosted by UN Environment, reveals that women of childbearing age living in four Pacific Island countries have elevated levels of mercury in their bodies. Mercury monitoring in women of childbearing age in the Asia and the Pacific Region, jointly conducted by the interim secretariat of the Minamata Convention, Biodiversity Research Institute (BRI), and the global NGO network IPEN, examined hair samples from women aged 18 - 44 from Cook Islands, Marshall Islands, Tuvalu, and Kiribati, and two landlocked Asian countries, Tajikistan and Nepal. The study found 96 percent of the women sampled from the Pacific Islands contained significantly elevated hair mercury levels. Researchers hypothesized that the Pacific Island participants may have a higher mercury body burden than other locations due to their relatively high consumption of predatory fish species shown to have elevated mercury concentrations in previous studies

Researchers from Ben-Gurion University of the Negev (BGU) and the University of Illinois at Urbana-Champaign (UIUC) have developed novel ultrafiltration membranes that significantly improve the virus-removal process from treated municipal wastewater used for drinking in water-scarce cities.

Current membrane filtration methods require intensive energy to adequately remove pathogenic viruses without using chemicals like chlorine, which can contaminate the water with disinfection byproducts. Researchers at UIUC and BGU collaborated on the new approach for virus pathogen removal, which was published in the current issue of Water Research.

California and more than two dozen other states require oil and gas producers to disclose the chemicals they use during hydraulic fracturing activities, enabling scientific and public scrutiny of the environmental and human health hazards these substances may pose. But all existing disclosure regulations cover chemical use only in hydraulic fracturing, known as fracking, and, in California, two other types of well-stimulation treatments. Many of the same chemicals used in hydraulic fracturing go undisclosed when they are used in numerous routine, unregulated oil- and gas-field activities such as the drilling, cleaning and maintenance of wells, according to a study published in PLOS ONE today. The study, conducted by scientists at the Lawrence Berkeley National Laboratory, University of the Pacific and the California-based energy science and policy institute PSE Healthy Energy, is the first published research to investigate chemicals used in unregulated routine oil- and gas-field activities, including the overlap between chemicals used in both regulated and unregulated activities.

Biostatistician Colin Weaver takes the same kind of algorithms and machine learning techniques that land a certain blender on your Amazon page or a suggested movie in your Netflix account, and he applies them to something slightly more consequential: health care.

Although human population studies have linked air pollution to chronic inflammation of nasal and sinus tissues, direct biological and molecular evidence for cause and effect has been scant. Now, Johns Hopkins researchers report that experiments in mice continually exposed to dirty air have revealed that direct biological effect.

Researchers have long known that smog, ash and other particulates from industrial smokestacks and other sources that pollute air quality exacerbate and raise rates of asthma symptoms, but had little evidence of similar damage from those pollutants to the upper respiratory system.
