| The Earth moves far under our feet: A new study shows the inner core oscillates Posted: 10 Jun 2022 12:29 PM PDT Scientists have found evidence that the Earth's inner core oscillates, contradicting previously accepted models that posited it consistently rotates at a faster rate than the planet's surface. |
| Despite dire warnings, monarch butterfly numbers are solid Posted: 10 Jun 2022 09:02 AM PDT Scientists have been warning for quite some time that monarch butterflies were slated for extinction due to diminishing winter colonies. But a new study found that warming temperatures and growth in the summer population of monarchs has compensated for losses during the winter. Researchers did preach continued caution, as the study did show continuing declines in other species of butterflies. |
| Ningaloo corals are ill-equipped to handle future climate change Posted: 10 Jun 2022 06:13 AM PDT The relatively pristine coral populations of WA's inshore Kimberley region are better equipped to survive ocean warming than the World Heritage-listed Ningaloo Marine Park, according to a new study. |
| How 'green islands' help forests regenerate after fire Posted: 09 Jun 2022 12:58 PM PDT A new study characterizes the role of fire refugia -- the green islands of live trees that remain after forest fires -- in forest regeneration following large and severe fires in the High Cascade mountains of Oregon and Washington. The results of this study can help determine when human intervention in the form of tree replanting is warranted, when it isn't, where replanting efforts should be targeted and what species should be prioritized. This is important to know since overplanting can be needlessly expensive and actually place forests at increased risk of future fires. |
| Posted: 09 Jun 2022 07:00 AM PDT Researchers identify why the fast fashion business model creates waste and whether regulators can establish incentives for consumers and manufacturers are steps to reducing waste. |
| Air pollution gets worse during winter at airports Posted: 09 Jun 2022 07:00 AM PDT Researchers found that airports situated in colder climates accumulated more pollutants like PM2.5 in the fall and winter, compared to airports in milder climates. |
| Opening of doors on passenger ships increases the risk of COVID-19 transmission, new study finds Posted: 08 Jun 2022 11:29 AM PDT A study has revealed that leaving open a cabin door on small passenger ships can increase the spread of COVID-19, contrary to advice for other environments. |
| Kelp connecting Southern Ocean coasts, genomics reveals Posted: 08 Jun 2022 08:24 AM PDT The DNA of kelp has enabled scientists to show just how interconnected coastal communities of the Southern Ocean are. A new study carried out genomic analyses of bull kelp washed up over decades in Antarctica, New Zealand and Australia. |
| Higher socioeconomic status linked to increased air pollution exposure in China Posted: 08 Jun 2022 06:14 AM PDT Researchers have uncovered that people living in China who have a higher socioeconomic status are actually more exposed to outdoor air pollution, also known as ambient air pollution. This finding runs contrary to existing studies conducted throughout North America, which have shown that higher pollution levels tend to be experienced among people with lower socioeconomic status. |
