After commercial whaling nearly erased them, blue and fin whales are slowly reclaiming the southeast Atlantic‎

More than 40 years after the end of commercial whaling, new research reveals a recent increase in sightings of the world's two largest whale species in the southeastern Atlantic. The findings, published in the African Journal of Marine Science, compiled more than 60 years of confirmed sightings and strandings from Namibia and South Africa's west coast. Although overall numbers remain low, sightings of both species have increased markedly in recent years—with 95% of observations recorded since 2012.

'Starwashing': How space companies use the greenwashing playbook while causing environmental damage‎

From launchpads to low Earth orbit and beyond, space companies and their affiliates are deploying a familiar marketing tactic—with a new twist. In a space economy projected to reach US$1.8 trillion by 2035, they sell space exploration narratives by appealing to a desire to expand humankind beyond Earth—while downplaying or omitting the negative repercussions for Earth and the space environment. Welcome to the age of starwashing.

The false and the furious: We aren't just bothered by different beliefs—we're bothered when we think others are wrong‎

Why do disagreements about vaccines, climate change or elections often feel so personal? Our research suggests it is not simply because other people have different beliefs. It is because we think those beliefs are mistaken.

Airborne observatory improves views of solar corona during cloud-covered eclipse‎

Using unique equipment installed on NASA's WB-57 aircraft flying above heavy clouds off the coast of Iceland, a Southwest Research Institute-led team successfully observed a total solar eclipse on Wednesday. The high-altitude jet followed the moon's shadow at 50,000 feet (15,000 meters) to take measurements of the solar corona in nine different wavelengths, ranging from visible to infrared light.

Wheat gene behind Hessian fly resistance cloned after 50-year search‎

Researchers at the University of Maryland and their collaborators have cloned a gene that makes wheat resistant to feeding by Hessian fly larvae and demonstrated its direct interaction with a protein produced by the insect. The research breaks through a longstanding barrier to understanding and engineering pest resistance in wheat. It is described in a research paper published Aug. 14, 2026, in the journal Science Advances.

Unlocking the past: New method helps gain insights into old tissues‎

A book sits atop a table. Although it's closed, its title, "Encyclopedia of Human Tissue," promises untold secrets. Perhaps with this book, you can learn about different cell types and what they look like under normal conditions or conditions of disease. Maybe you can learn how gene expression differs in the cells of younger and older people, or whether different patients' cells respond differently to the same treatments.

Europe's mountain summits are warming—vegetation is responding in surprisingly different ways‎

Decades of climate change have not left Europe's mountain vegetation unscathed. However, the changes observed do not always match expectations. As a new international study by a research team led by researchers from the University of Vienna, the Austrian Academy of Sciences and the BOKU University shows, alpine vegetation has shifted significantly towards warmth-associated species. However, the direct link between this so-called thermophilization and local warming is surprisingly weak. The study has recently been published in the journal Nature Ecology & Evolution.

Engineered microbe speeds CO₂ capture and recovers critical metals‎

A genetically engineered bacterium can rapidly break down one of Earth's most abundant minerals, opening a promising new pathway for simultaneously removing carbon dioxide from the atmosphere and recovering critical elements used in electric vehicle batteries, according to new Cornell research.
