U.S. children and adolescents see thousands of food marketing messages on digital media platforms each year, according to new research published in JAMA Pediatrics. And 92% of the marketed food and beverage products are considered unhealthy.

Understanding the sources and quantities of carbon dioxide (CO₂) released to the atmosphere is central to assessing past emissions and identifying potential reductions. Fossil fuel combustion is the principal source of human-caused CO₂ emissions, alongside emissions from natural gas flaring and venting and the manufacture of cement. Consistent estimates across countries and years help distinguish changes in emissions from changes in data coverage or accounting methods. The CDIAC-FF dataset provides annual estimates reaching back to 1750 and records emissions by fuel type and, for recent decades, economic sector.

Authors Michael Erb and Gregg Marland from the Research Institute for Environment, Energy and Economics at Appalachian State University updated the CDIAC-FF dataset through 2022. The research describes a data product, using United Nations Statistics Division energy data for fuel production, trade and consumption from 1950 onward, with earlier estimates drawn from historical sources. The authors estimate emissions using both a reference approach based on apparent national fuel use and a sectoral approach based on consumption by economic sector. The inventory covers fossil fuel use, natural gas flaring and venting, and cement production, with national and global estimates kept within consistent accounting boundaries over time.

Companies face growing pressure to recognize and report climate-related risks, but more discussion of climate change does not necessarily mean that a company has reduced its emissions. Annual-report language can reflect attention, reporting requirements, compliance, or pressure from investors and regulators; it is not a direct measure of managers’ private beliefs or of action taken to cut carbon.

Authors Mohammad Haseeb, Miguel Angel Esquivias, and colleagues from Bahçeşehir Cyprus University, Chitkara University, Universitas Airlangga, Baku Engineering University, European University of Lefke, Al-Ahliyya Amman University, Termez University of Economics and Service, and Tashkent State University of Economics examined Chinese A-share listed firms from 2011 to 2024. They used climate- and carbon-related language in annual reports as an indicator of expressed climate-risk attention and analyzed its association with estimated firm-level CO₂e using firm and year fixed effects, additional fixed effects, and double machine learning.

Researchers from Flinders University and the South Australian Health and Medical Research Institute (SAHMRI) have conducted a major new study which examined the financial circumstances, sources of income and homeownership of more than 920,000 older people (average age 82) who applied for aged care between 2010 and 2019.

In findings recently published in Parasites and Vectors, Virginia Tech’s Warren Booth cites evidence that bed bug infestations can affect anyone regardless of income, housing type, or location. The findings indicate bedbug management strategies should evolve to a more coordinated, community-level approach. Booth shares insights about this work and the unpopular pest.

University of Vermont researchers use serious-game research methodology to uncover how flood-warning communication design can improve fast decision-making and reduce risk during flood events.

Companies increasingly market environmentally friendly products, but it remains unclear whether highlighting multiple sustainability benefits improves consumer evaluations. A new study examined responses to sustainability claims across three studies in Japan. Consumers with stronger green consumption values evaluated products more favorably when both composition and packaging were highlighted, whereas those with weaker values preferred a single focus. The findings suggest that sustainability communication may be more effective when tailored to consumers’ environmental values.
