Sweetened beverage taxes decrease consumption in lower-income households by nearly 50%
|
New research investigated responses to sweetened beverage taxes using the purchasing behavior of approximately 400 households in Seattle, San Francisco, Oakland and Philadelphia. Researchers found that after the tax was introduced, lower-income households decreased their purchases of sweetened beverages by nearly 50%, while higher-income households reduced purchases by 18%.

More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urban development.

Shaking from April's sizable New Jersey earthquake traveled strangely far
|
When a magnitude 4.8 earthquake struck northern New Jersey's Tewksbury township on April 5, it triggered widespread alarm as the biggest event since 1884. Based on existing models, it should have done substantial damage at its epicenter, but that didn't happen. Meanwhile, relatively distant New York City shook much harder than expected, causing damage, albeit minor. Outsize shaking extended all the way to Virginia and Maine. A new study suggests why this happened, calling into question some assumptions about regional earthquake hazard.

Understanding the relationship between food waste, climate change, and aging population
|
Household food waste is an important contributor to global food loss and waste and greenhouse gas emissions, but not much is known about what types of food are wasted the most and by whom. Now, researchers investigated the relationship between food waste, food type, and various socioeconomic and demographic factors. Their findings will help us develop sound strategies to minimize food waste in Japan and other aging developed countries.

The 2022 European drought: What was the role of climate change?
|
The drought that lasted through the summer of 2022 was especially intense and caused the soil in many regions of Europe to dry out substantially. Public discussions about the causes repeatedly broached the question of the extent to which climate change intensified this extreme weather event. A research team has now discovered that more than 30 percent of the extraordinary intensity and physical extent of the drought can be attributed to human-induced climate change. This extreme event was exacerbated by the fact that climate change had already caused soil moisture levels to drop continuously over the previous years.

U.S. babies died at a higher rate in the months following the Supreme Court's 2022 Dobbs v. Jackson Women's Health decision, and infant mortality was highest among those born with chromosomal or genetic abnormalities, new research has found. The findings mirror previous research analyzing the experience in Texas after a ban on abortions in early pregnancy and illuminate the consequences of restricting access to abortion care, said researchers who conducted the national analysis.

Connectivity particularly impacted herbivorous reef fish groups, which are most critical to coral reef resilience, providing evidence that decision-makers should incorporate connectivity into how they prioritize conservation areas.
