Science X / California's most iconic trees are entering a silent collapse that could remake forests, rangelands and coastlines
From the scarecrow-like silhouettes of Joshua Tree National Park to the fog-shrouded Redwood Coast of Mendocino and Humboldt counties, California's identity is deeply rooted in its trees. However, a new study led by researchers ...
Phys.org / Single X-ray photons reveal hidden light-matter interactions in 50-nanometer double slits
A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water droplets. This same physical effect underlies many everyday technologies, like LCD screens and broadband ...
Phys.org / Light-based scans reveal how cells can be stable yet adaptable
Our cells adjust to ever-changing conditions while preserving internal states necessary for survival, but exactly how they achieve both adaptability and stability remains unclear. For the first time, researchers have used ...
Phys.org / Rivers worldwide reveal greenhouse gas rise that's been overlooked for decades
Rivers worldwide are under severe stress: they are warming, losing oxygen, and as a result emitting increasing amounts of greenhouse gases. Researchers at Karlsruhe Institute of Technology (KIT) have now quantified these ...
Medical Xpress / Minimally invasive procedure outperforms drugs for advanced atrial fibrillation
A minimally invasive heart procedure may be a better first-line treatment than medication for people living with advanced forms of atrial fibrillation, according to a major international clinical trial led by researchers ...
Phys.org / Fragile no more, nickelates get an upgrade that changes how superconductivity endures
Discovered in 2019, the material known as nickelates has intrigued researchers for its potential to become a superconductor at elevated temperatures—a property that could significantly advance such fields as quantum science ...
Phys.org / Breaking connections helps ideas spread farther, says physics-based study
Sticking with the same people might feel safe and comfortable. But a new Northwestern University study suggests it can actually trap new ideas and behaviors inside tight echo chambers. By contrast, the research, published ...
Medical Xpress / Children may be born with two complex cognitive functions already established, research reveals
A new study is the first to show that two of our most sophisticated cognitive functions, using and understanding language and being able to sense how other people feel, have distinct origins in the brain in young children—matching ...
Phys.org / Aligned cells may explain why some wounds heal faster than others
Understanding how wounds heal after injury could be a step closer thanks to a new mathematical model developed by researchers at the University of Bristol. The study, published in Physical Review Letters, builds on previous ...
Phys.org / Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface ...
Science X / Crows look plain black to us, but their feathers contain a secret visual code that changes with age
To understand birds—their social relationships, their choices, even their feathers—you need to understand the way they see the world. That can be a challenging task, because birds and humans literally see their environments ...
Phys.org / Two suns are better than one—planets thrive around binary stars
Planets may actually form more easily around double stars than around single stars like our sun, according to new research from astrophysicists at the University of Lancashire. Binary stars are common in our galaxy, yet for ...
