In August of 2018, scientists published research showing how air pollution shaves off about a year on average from human life expectancy. In more polluted regions of Asia and Africa, lives are shortened by 1.5–2 years on average. Loss in life expectancy rises with increasing concentrations of fine particulate air pollution (PM2.5).

According to a 2022 study, people in the United States often included Thanksgiving as an event important to the country’s foundation along with the Revolutionary War, the Declaration of Independence, Christopher Columbus’s “discovery” of the Americas, the Civil War and British colonization. But the events in most people’s narrative of the first Thanksgiving run contrary to history. Thanksgiving myths abound because their memory is rooted in story. While such origin stories tend to unify people, they sometimes misrepresent the truth. Tidy tales of history sometimes appear in books and museum exhibits, preserving the group narrative and identity.

In February 2024, a team of researchers collected 580,000 records on domestic dogs in the United Kingdom. On average, dogs live roughly 10 to 14 years. Overall, dogs from pure breeds that are small and have a long nose seemed to have longer life spans. But some flat-faced dogs, such as Tibetan mastiffs, had an average life span of 13 years.

Since temperature record-keeping began 150 years ago, the 12-month period from November 2022 through October 2023 was the hottest on record until temperatures in 2024 exceeded those in 2023. The heat raised sea surface temperatures, melted sea ice and endangered human health.

In 2023, the expanse of floating ice encircling Antarctica hit record lows throughout the year. Scientists expect dramatic declines in sea ice at Earth’s other pole but hadn’t observed major changes in the Antarctic until the last few years.

Our first Science News Explores educator guide highlights an article type called Explainers that takes a deep dive into a key scientific concept or process. Use this guide to build a lesson plan based on any Explainer article, learn about the Cornell Note-taking system and download a student template and have students investigate new species found in […]

Ocean explorers just uncovered a treasure trove. A newly discovered undersea mountain may be home to 20 new species. Explore these life forms while answering questions about the value of such discoveries in a time of rapid climate change.

Use this lesson plan to learn about an article type called Explainers that is published by Science News Explores in print and online. You can also access a lesson plan template that can be used with any Explainer article. Explainer articles take a deep dive into a key scientific concept or process.

Use this lesson plan and the provided template to have your students practice the Cornell Note-taking System with any article. This literacy strategy organizes notes into two columns that provide structure for note-taking, analysis and review and that will help increase students’ learning, comprehension and retention.

Use one of the literacy templates in this guide with any Science News or Science News Explores article. Each template guides students through a different literacy strategy to help increase effective learning, comprehension and retention. These templates were created in collaboration with our Science News Learning Literacy Ambassador Janice Lewis.

Climate scientists are continuing to develop new methods to sequester atmospheric carbon to help curb climate change. In this activity, students will learn about how carbon can be sequestered through the burial of organic material and review the carbon cycle. Students will practice using percent by mass concepts and dimensional analysis to calculate how much wood would need to be buried to achieve climate targets by the year 2060. As an optional extension, students may then develop a plan to mitigate greenhouse gas production that utilizes biomass burying techniques.

Use articles from the January issue of Science News to review components of respiration and photosynthesis while students investigate what impact megafire smoke may have on California nut trees and have students explore how a Dune-inspired spacesuit may filter urine into drinkable water.
