Phys.org / Urban growth may slow by 2100, leaving big cities smaller than expected
The world is urbanizing fast. In 1975, about 11% of the global population lived in cities with more than 1 million inhabitants. "Today, we estimate that share to be about 24%," says Andrea Musso, junior fellow at the Complexity ...
Phys.org / New cellular model for rare and deadly melanomas enables study of immunotherapy resistance
A research team at the University of Turku in Finland has developed a reliable laboratory model to study BAP1-deficient melanomas, which are a rare type of melanoma that evade the immune system once they have metastasized ...
Phys.org / Why people worldwide see some mental abilities as inborn and others as learned
When does a child begin to reason? When do they develop self-control? Are some mental abilities present from birth, while others are acquired through experience? Questions like these have fascinated philosophers, educators ...
Phys.org / When mitochondria grow abnormally long, leaked RNA may activate anti-tumor immune responses
Researchers from the University of Osaka have demonstrated that mitochondrial hyperfusion, when induced by low levels of DRP1 or cellular stress, activates an immune response through the RIG-I–MAVS pathway. Dependent on the ...
Phys.org / Spiders benefit from seemingly monotonous forests
In ecology, the principle holds that the more diverse and heterogeneous a habitat is, the more different species it supports. To promote species diversity in forests, clearings are therefore created for nature conservation ...
Phys.org / Nova V612 Scuti's light curve becomes audio, revealing how stellar shocks evolved
Researchers in the Department of Physics & Astronomy at Texas Tech University recently used audio to represent the spectacular explosion of a star in deep space while also delving into the data to better understand how the ...
Phys.org / UV light patterns thermochromic crystals without damage, unlocking color-changing designs
Color-changing mood rings, forehead fever strips and car-shade indicators all change hues as they warm and cool, thanks to a phenomenon called thermochromism. On a smaller scale, thermochromism is used in nanotechnologies ...
Phys.org / Nanopore technology identifies proteins molecule by molecule
Proteins are responsible for most functions in the human body. However, their analysis, which is essential for understanding diseases, developing drugs and discovering new biomarkers, remains highly complex. Using a technology ...
Phys.org / Cyclic sealing and drainage on the Gofar Oceanic Transform Fault revealed
Oceanic transform faults are strike-slip boundaries—faults that move horizontally rather than up and down and connect offset mid-ocean ridge segments. They have long been regarded as simple "conservative" plate boundaries ...
Phys.org / Uncovering the trigger behind slow earthquakes
New research led by the University of New England's Dr. Timothy Chapman has uncovered the trigger behind slow earthquakes, providing valuable answers for those living in disaster-prone areas. The research has been published ...
Phys.org / Understudied enzyme helps S. aureus pathogen prosper, study finds
A new study published in the Proceedings of the National Academy of Sciences has offered insight into how Staphylococcus aureus, a major human pathogen, fine-tunes its internal machinery to survive stress and potentially ...
Phys.org / Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better than others
RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed ...
