Broadly falling under environmental, social and governance or ESG, this involves practices such as using sustainably sourced materials, reducing carbon emissions, improving labor practices, fostering positive community relations, and promoting ethical corporate behavior, including efforts against anti-competitive practices and corruption.   The first mention of ESG appears in a 2004 UN report ...

With global goals set on transitioning away from fossil fuels, fuel cells stand out as a promising carbon-free energy source. Comprising an anode and a cathode separated by an electrolyte, fuel cells convert the chemical energy of fuel directly into electricity. The anode receives the fuel, while an oxidant, typically oxygen from the air, is introduced at the cathode. In a hydrogen fuel cell, hydrogen undergoes oxidation at the anode, producing hydrogen ions and electrons. The ions move through the electrolyte to the cathode, and electrons flow through an external circuit, generating electricity. At the cathode, oxygen combines with the hydrogen ions ...

DURHAM, NC – Living in a poorer neighborhood is linked to accelerated brain aging and increased dementia risk early in life, regardless of income level or education, a Duke University-led study finds. The study, which appears March 14 in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, suggests that targeting disadvantaged neighborhoods for dementia prevention programs and encouraging clinicians to consider a patient’s address could help lower dementia risk. “If you want to prevent dementia, and you’re not asking someone ...

UC Riverside scientists confirm, for the first time, that a potentially fatal dog parasite is present in a portion of the Colorado River that runs through California.  The parasite, Heterobilharzia americana, is a flatworm commonly referred to as liver fluke.

Researchers at the Francis Crick Institute have shed light on how cancer cells survive in the first few hours after being cut off from a supply of oxygen. Published today in The EMBO Journal, this finding could one day help to prevent cancer from becoming resistant to therapy. A major use of oxygen by cells is for energy production. When oxygen supplies are low, most cells can survive because they adapt, by changing which proteins they make, to produce energy through different processes than in normal oxygen levels. This is coordinated by a protein called HIF1α, which turns on the activity of genes. Although HIF1α ...

Research Highlights: In a review of data for more than 90,000 veterans hospitalized with stroke, African American veterans who had been previously diagnosed with post-traumatic stress disorder (PTSD) were significantly more likely to be re-hospitalized than African American veterans without PTSD. In contrast, white veterans with PTSD were not significantly more likely to be re-hospitalized after stroke than white veterans without PTSD. Illicit drug use and Type 2 diabetes also raised the hospital readmission risk in African American veterans ...
