Researchers preparing slides of live bacteriophages were surprised to see them link and form naturally into three-dimensional flower shapes in reaction to contact with high-pressure carbon dioxide. The discovery is welcome news for researchers who had been trying to network phages articifially to boost their power.
Plants the world over are absorbing about 31% more carbon dioxide than previously thought, according to a new assessment developed by scientists.
A species of tropical butterfly with unusually expanded brain structures display a fascinating mosaic pattern of neural expansion linked to a cognitive innovation.
Michigan’s rivers and lakes were once cold enough that fish were protected from some infection-causing parasites. As the Great Lakes ecosystem warms, a Michigan State University researcher is investigating new pathogens that may become relevant to the fish that live here.
An Iowa State University plant biologist received a $1.8 million federal grant to study a gene that affects both how plants grow and how they respond to environmental threats. Unraveling the balancing act between fortifying and flourishing could help scientists develop crops that are more resilient in challenging conditions.
Alaska’s Iliamna Lake harbor seals have been difficult to study because of their remoteness. They weren’t even identified as harbor seals until 2013. Now, a new genetic study has found significant differences, indicating that the Iliamna seals may represent a unique, endemic form of harbor seal. Findings suggest they may be evolutionarily, reproductively, and demographically distinct from other Pacific harbor seal populations sampled across the Pacific, including Japan, the Commander Islands, other parts of Alaska, and California.
With vigorous debate surrounding the health of the monarch butterfly, new research from the University of Georgia may have answered the biggest question plaguing butterfly researchers. Why are the wintering populations declining while breeding populations are stable? Published by the Proceedings of the National Academy of Sciences, the study suggests that monarchs are dying off during their fall migration south to Mexico.
In the ongoing effort to enhance crop efficiency, researchers have uncovered key genetic components of photosynthesis in tomatoes. A new study highlights the PetM domain-containing protein, crucial for the electron transport chain in chloroplasts, and its role in plant growth under different light conditions. By knocking out the PetM gene, scientists observed significant effects on photosynthesis, providing fresh insights into how plants adapt to varying light environments. This discovery could pave the way for improving crop resilience and productivity.
Climate change has a negative impact on food security. An international research team led by Wolfram Weckwerth from the University of Vienna has now conducted a study to investigate the natural variation of different chickpea genotypes and their resistance to drought stress.
The interlinked global crises of biodiversity loss, climate change, and threats to human and wildlife health are continuing to accelerate, posing existential threats to biodiversity and human well-being, and undermining efforts to implement the Global Biodiversity Framework. Maintaining and improving ecological integrity–structure, composition, and function–is central to addressing all three of these crises, and its importance is reflected within the GBF and the UNFCCC Paris Agreement.
New research indicates that to keep Miami’s tree canopy resilient, tropical species may be the best option for local municipalities and environmental leaders to consider.
Rapid warming has impacted the northern ecosystem so significantly that scientists are concerned the region’s vegetation is losing the ability to recover from climate shocks, suggests a new study.
Researchers have identified how the architecture of brain circuits helps different species flexibly adapt to new mating signals across evolutionary timeframes.
Computational protein design and protein structure prediction have earned three scientists the 2024 Nobel Prize in Chemistry. David Baker, a Howard Hughes Medical Institute (HHMI) Investigator at the University of Washington School of Medicine, and Demis Hassabis and John M. Jumper of Google DeepMind were announced as this year’s recipients by the Royal Swedish Academy of Sciences today.
An Atikamekw First Nation community is collaborating with UdeM researchers to create a digital platform to pass on ancestral knowledge about the land.
With help from scientists at U.S. Department of Energy (DOE) national laboratories, DOE's Atmospheric Radiation Measurement (ARM) user facility has established a cutting-edge atmospheric observatory in Alabama's William Bankhead National Forest.
Biodiversity encompasses much more than the number of species—it includes the variety of ecosystems, the genetic diversity within and between species, and the interactions among species within ecosystems.
A few years ago, I had the opportunity to hear Terry Tempest Williams speak at a local event. I don’t remember many details of her talk, but I do remember her passion, her commitment, and her dedication to being a voice for the environment. Her book, Finding Beauty in a Broken World has been a guidepost for me as a science writer and writing instructor.
It’s August in South Dakota and a weeklong heat wave where temperatures surpassed 100 degrees has just ended. Thankful for a reprieve from the stifling warmth, I head out early on my day off to explore Badlands National Park. I’ve been staying in Fort Pierre, which is situated on the Missouri River, just across from the capital city of Pierre.
