Phys.org / Molecular fingerprints reveal how human activities alter water systems worldwide
A Florida State University–led review shows how ultrahigh-resolution mass spectrometry can help researchers identify the molecular fingerprints of human activity in water systems around the world.
Phys.org / AI reveals a shared language guiding cell development
As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized roles like brain, liver or muscle cells and organize themselves into three-dimensional structures ...
Phys.org / Essential oil sprays kill cockroaches on contact but offer little lasting control
A German cockroach races across a kitchen floor. Someone grabs a bottle of essential oil spray, soaks the insect and watches it die. The product worked, but a new University of Kentucky study suggests the larger infestation ...
Phys.org / Machine learning analysis of gene regulation reveals new dimension of biological variability
Changes in our genes affect health risks from heart disease to cancer, but how those genes are turned on and off is just as crucial to health. What's more, almost all genes occur as two copies—one from each parent—that aren't ...
Phys.org / Supercooled clouds over the highest mountains respond differently to climate change
Most studies of how clouds are responding to climate change focus on clouds over the oceans, rather than over mountains. Those that do focus on mountain clouds tend to explore cloud microphysics rather than long-term trends ...
Phys.org / The force behind our strength: How mechanical processes regulate muscle development
Skeletal muscles grow and regenerate as individual precursor cells—called myoblasts—fuse into long fibers from which mature muscle fibers develop. How they coordinate this process and form functional muscles is not yet fully ...
Phys.org / New 3D model reveals how shadows reshape chemistry in stellar nurseries
How do young stars reshape the clouds from which they are born? A new high-resolution 3D model developed by an international team led by Dr Brandt Gaches from the University of Duisburg-Essen shows how the uneven structure ...
Phys.org / Wider approach needed to mitigate rising rechargeable battery emissions
A new University of Melbourne-led study has identified insights and evidence that could help mitigate the fast-rising climate impact of lithium-ion batteries (LIBs).
Phys.org / Climate warming can slow how tree roots feed soil microbes
A plant's roots do much of their work out of sight, pulling in water and nutrients and holding the plant in place. That makes it hard to see how plants respond when conditions underground change, and how a warming climate ...
Phys.org / Adaptive molecular convergence more common than previously thought, distant jellyfish relatives reveal
A new study has found that adaptive molecular convergence—the process by which distantly related or unrelated species evolve the same genomic changes—is not as rare as previously thought.
Phys.org / Physics-guided AI reconstructs hidden patterns inside ultrathin magnets from external fields
To build faster and more energy-efficient computers, researchers need to understand nanoscale magnetic materials. But looking inside these tiny magnets is surprisingly difficult: Modern microscopes only measure the magnetic ...
Phys.org / Even or odd numbers: A single molecule makes all the difference in the quantum world
The researchers in the Quantum Detection Microscopy group at CIC nanoGUNE, in collaboration with chemists at CiQUS of the University of Santiago de Compostela, have demonstrated that adding or removing a single molecule from ...
