Yogurt waste inspires researcher to innovate with sourdough bread
If you were one of the many amateur bakers who learned to bake sourdough bread during lockdown, you'll know how complex a single loaf can be. The rise of the bread, moisture, firmness and even crumb structure can make or break a baker's creation. It's why Latifeh Ahmadi,
Climate change could fragment habitat for monarch butterflies, disrupting mass migration
Suitable habitat for migrating monarch butterflies will shift southwards because of climate change, according to a study published in PLOS Climate by Francisco Botello and Carolina Ureta at the National Autonomous University of Mexico and colleagues.
Tropical flowers are blooming weeks later than they used to through climate change
Climate change has caused some tropical plants to flower earlier or later than they used to; in some cases by a matter of weeks or even months, according to a study of 8,000 flowers across more than two centuries, published in PLOS One by Skylar Graves and Erin Manzitto-Tripp
Risk of whale entanglement in fishing gear tied to size of cool-water habitat
New research shows that, off the U.S. West Coast, humpback whales face a higher risk of getting entangled in fishing equipment during years with lower availability of cool-water habitat, where the whales feed. Jarrod Santora of the National Oceanic and Atmospheric
This mysterious protein punctures our cells—now researchers know how
The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's systems in balance. A new study from Northeastern University researchers
Why corals bleach: Neutrons show algae photosynthesis breaking down
Rising sea temperatures are causing coral reefs around the world to bleach. For the first time, a research team at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) at the Technical University of Munich (TUM) has investigated the biological processes behind coral
Combination of wildfires and seismic lines may limit spread of non-native plants in Canada's boreal forest
A pair of disturbances common in Western Canada's boreal forests, when combined, may have an unexpected benefit of limiting the spread of non-native plant species, a University of Alberta study shows. The research gauged the interactive effect that natural wildfires and the
Source or sink? Trees with heart rot disease emit more methane, upending forest carbon models
Throughout their lifetimes, healthy forests produce more oxygen than they use, while taking in greenhouse gases via plants and soils. This ecosystem-wide service, called carbon sequestration, regulates global climate and is an essential component of climate models and goals.
NASA astronaut Mike Fincke identified as having experienced the medical event on the ISS that triggered an evacuation
This disclosure comes about a month after NASA made the decision to evacuate the four members of Crew-11 from the International Space Station
Ocean carbon blind spot may skew climate forecasts
A new report by the Intergovernmental Oceanographic Commission (IOC) of UNESCO reveals a critical lack of understanding of how the ocean absorbs and stores carbon. This glaring uncertainty about our planet's largest carbon sink threatens to skew current climate predictions, and
Fungi could transform leftovers into lifelines
As the global population climbs toward 10 billion and climate change strains farmland, scientists are searching for new ways to feed the world. A group of Cornell food science researchers say one answer may lie not in fields of soy or herds of cattle, but in networks of fungi

Collateral damage: Japanese beetle traps snare nature's helpers
The Japanese beetle (Popillia japonica) is one of the most dreaded insects to have invaded North America and parts of Europe. Accidentally introduced to the United States in the early twentieth century, it can now be found from Vancouver to the Alps and beyond. Japanese beetles
Would you feel comfortable talking to your boss if you had a problem with alcohol or other drugs?
For many Australians working in high-risk industries, the answer is a resounding no, and that's a problem. A new study by Flinders University reveals that fear of punishment and lack of trust in management are major barriers to tackling alcohol and drug risks at work.
Land plants began reshaping Earth 455 million years ago, scientists discover
Pinpointing when early land plants colonized terrestrial environments and began influencing Earth's systems is a core question in the evolution of the Earth system. A research team led by Prof. Zhao Mingyu at the Institute of Geology and Geophysics of the Chinese Academy of
