Phys.org / Paternal mitochondria in plants can rescue defective maternal DNA, study reveals
In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother. By contrast, paternal transmission is observed only occasionally, and the mechanisms behind this ...
Phys.org / Asteroid Ryugu samples offer new insights into early solar system magnetism
To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread magnetic field of the ...
Phys.org / Permafrost is key to carbon storage. That makes northern wildfires even more dangerous
The devastating wildfires in northern Canada in recent years have climate consequences that go far beyond smoke and carbon dioxide released into the atmosphere, according to a new study co-authored by two NAU researchers. ...
Phys.org / Modern twist on wildfire management methods has a bonus feature that protects water supplies
Wildfires are among the most economically costly natural disasters and are becoming more severe and frequent due to global warming. The United Nations Office for Disaster Risk Reduction estimates that global damage from wildfires ...
Phys.org / The 'Bloom cycle' is a newly described biochemical pathway that explains key plant processes
For decades, the basics of plant growth have been taught in grade school: Plants make their food out of water from the soil, light from the sun and carbon dioxide from the air in a process called photosynthesis. What gets ...
Phys.org / Hard-to-make diastereomers: How a cage-like allyl reagent changes the outcome
Diastereomers are structurally identical molecules that are not mirror images of each other. Diastereomers can have different biological activities, potencies or toxicities, which means they can influence biological systems, ...
Dialog / The wetland puzzle that stumped hydrology for decades—how physics and AI joined forces to predict unmeasured regions
For years, the Prairie Pothole Region has bothered me in a very specific way. On a map, it looks like a normal landscape: fields, gentle slopes, small streams. But hydrologically, it behaves like something else entirely. ...
Phys.org / Chemically 'stapled' peptides used to target difficult-to-treat cancers
Researchers at the University of Bath have developed a new technology that uses bacteria to build, chemically stabilize, and test millions of potential drug molecules inside living cells, making it much quicker and easier ...
Phys.org / Jackdaw chicks listen to adults to learn about predators
Jackdaw chicks learn about predators by listening to adults, new research shows. Scientists played recordings of predator calls to chicks in their nests—and paired the sounds with either adult jackdaw "alarm" calls or "contact" ...
Phys.org / Rainfall can shape bird populations as much as temperature, global study reveals
Scientists have long focused on rising temperatures to understand how climate change is reshaping the natural world. But there's a critical blind spot in that picture: rain. A new global study reveals precipitation has been ...
Phys.org / Letting atomic simulations learn from phase diagrams
A new computational method allows modern atomic models to learn from experimental thermodynamic data, according to a University of Michigan Engineering and Université Paris-Saclay study published in Nature Communications. ...
Phys.org / 'Mismatched' plant water isotopes vanish with better sampling: Study points to better drought forecasts
For decades, scientists have relied on a chemical fingerprint inside water molecules to determine where plants get their moisture. The method shaped our understanding of drought resilience, groundwater use, and ecosystem ...
