Phys.org / New tissue atlas aims to help AI understand cancer
How cells are arranged within tissue can reveal as much about disease as the cells themselves. When doctors examine a cancer tumor, for example, they don't just look at which cells are present; they also want to know how ...
Phys.org / Machine learning simulations reveal how plastic transforms into hard carbon
In a new study published in Chemical Science, researchers from the University of Oxford's Department of Chemistry have used machine learning simulations to trace how a common polymer transforms into hard carbon, revealing ...
Phys.org / Macromolecular crowding could help build artificial cell systems
Macromolecular crowding can serve as a design tool for controlling the formation and organization of synthetic DNA droplets, a study from Science Tokyo reveals. Researchers investigated this strategy using DNA nanostars and ...
Phys.org / When simulations fall short, this spectrometer learns for itself
An NMR spectrometer can reveal molecular structure down to the atomic level, but weak signals limit what it can see. Now, Aarhus University researchers have used AI to let the spectrometer learn the best pulse sequence directly ...
Phys.org / Ants prioritize brain energy during starvation, echoing pattern seen in humans
The human brain accounts for roughly 2% of total body weight but uses approximately 20% of our body's energy. Relative to our body size, human brains are much larger than those of other mammals and take a lot of energy to ...
Dialog / Explaining the difference between brittle and ductile behavior in polymer glasses
Glasses are (mostly) brittle, metals can be ductile (plastic), and liquids flow easily. Polymers are interesting because they exhibit all three types of behavior, depending on their chemical nature, temperature, and deformation ...
Phys.org / Amber fossils reveal how ancient Australian landmass helped seed Southeast Asia's tropical forests
A landmass that broke away from northwestern Australia about 150 million years ago and drifted north for the next 100 million years helped lay the foundations for Southeast Asia's extraordinarily diverse tropical forests, ...
Phys.org / Molecular architecture determines tomato plant resistance to its main pest
An international study investigating why wild tomatoes are more resistant to the tomato leafminer (Phthorimaea absoluta) than cultivated varieties revealed that the secret lies in the spatial structure of a plant defense ...
Phys.org / Islands harbor nearly 20% of Earth's biodiversity, yet remain overlooked in conservation strategies
Although they account for just 7% of the Earth's land surface, island ecosystems harbor almost 20% of the world's biodiversity. From sea-level rise to biological invasions, islands are facing multiple pressures associated ...
Phys.org / Eaton Fire may have exposed nearly 7 million people to elevated lead levels
Caltech scientists have published the first detailed analysis of the atmospheric particles in the smoke plume from the Eaton Fire that devastated much of the town of Altadena in Southern California's San Gabriel Valley and ...
Phys.org / Controlling where gibberellin acts reveals how the plant hormone coordinates root growth
Plant hormones influence growth and development by acting on specific cells and tissues. However, determining precisely where and when a hormone needs to act has been challenging because conventional hormone treatment generally ...
Phys.org / Why hugs become memorable
A large-scale survey of adults in the U.K. shows that hugs are commonly remembered for comfort, support and understanding, according to a study published in PLOS One by Anna Lena Dueren of the University of Bristol, U.K., ...
