Phys.org / Classic recessive-or-dominant gene dynamics may not be so simple
Populations live in rapidly changing environments—droughts come and go, food sources change, human activities reshape habitats. For scientists, this raises a fundamental puzzle: How do populations maintain the genetic diversity ...
Phys.org / When does melting ice capsize? New research unearths several mechanisms
Rising temperatures of the world's oceans threaten to accelerate the melting and splintering of glaciers—thereby potentially increasing the number of icebergs and, with it, the need to better understand more about their ...
Phys.org / Next-generation nanoengineered switches can cut heat loss in electronics
Electronic devices lose energy as heat due to the movement of electrons. Now, a breakthrough in nanoengineering has produced a new kind of switch that matches the performance of the best traditional designs while pushing ...
Phys.org / Mars Perseverance rover data suggests presence of past microbial life
A new study co-authored by Texas A&M University geologist Dr. Michael Tice has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA's Perseverance rover.
Phys.org / Ten years later, LIGO is a black-hole hunting machine
On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of ...
Phys.org / Want to hear dinosaurs 'sing'? These instruments bring prehistory back to life
The roar of a T. rex, made iconic by Jurassic Park, has become the soundtrack of prehistory.
Phys.org / Saturday Citations: A mechanism for liver failure; LIGO black hole kick observed; primordial black hole explosions
This week, researchers reported on a new biopsy tool that can detect HPV-associated head and neck cancer up to 10 years before symptoms appear. Researchers developed a process to transform two-dimensional paintings into full-color, ...
Phys.org / Mini microscope enables real-time 3D brain imaging in freely moving mice
Researchers at the University of California, Davis, have created a miniaturized microscope for real-time, high-resolution, noninvasive imaging of brain activity in mice. The device is a significant step toward revolutionizing ...
Phys.org / Cheese cave fungi reveal how genetic mutations drive rapid evolutionary change
Many scientific discoveries are serendipitous—the result of chance. Seeing evolution in action in a cheese cave turned out to be exactly that for Benjamin Wolfe, associate professor of biology, and his colleagues.
Phys.org / Mysterious 'red dots' in early universe may be 'black hole star' atmospheres
Tiny red objects spotted by NASA's James Webb Space Telescope (JWST) are offering scientists new insights into the origins of galaxies in the universe—and may represent an entirely new class of celestial object: a black ...
Phys.org / Atomic-level engineering enables new alloys that won't break in extreme cold
Navigating the extreme cold of deep space or handling super-chilled liquid fuels here on Earth requires materials that won't break. Most metals become brittle and fracture at such low temperatures. However, new research is ...
Phys.org / New metrics indicate habitat fragmentation has increased in over half the world's forests over the last 20 years
Deforestation is a well-known issue affecting biodiversity and carbon storage, but the fragmentation of forests is also a driving factor in the reduction of the world's biodiversity and carbon-storing abilities.
