Phys.org / Stem cell regulators in Arabidopsis and maize reveal agricultural potential
Plant stem cells are crucial for the world's food supply, animal feed, and fuel production. They lay the foundation for how plants grow. Yet, much about these mysterious building blocks remains unknown. Previous analyses ...
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 / Can microbes be the good guys? Research reveals Hollywood's blind spot
Hollywood and commercial cinema often portray microbes as villains—causing deadly epidemics, fueling apocalyptic scenarios, or being weaponized for destruction. This stereotype reinforces a cultural bias known as germophobia. ...
Phys.org / Island haven for threatened koalas faces genetic 'trap' without intervention
Kangaroo Island in South Australia is home to a large, mostly disease-free koala population which, at first glance, looks like a conservation success story.
Phys.org / Rapid wildlife tracking offers early warning system for pandemic protection
When the next pandemic threat looms, help may come from an unexpected source: wild animals. In a new study led by Prof. Ran Nathan from the Movement Ecology Lab at the Hebrew University of Jerusalem, researchers propose a ...
Phys.org / Two routes, one goal: How the crown of cell division is manufactured
Cell division is one of the most thoroughly studied processes in biology, yet many of its details remain mysterious. A century-old puzzle surrounding the "crown" of cell division—the kinetochore corona—has now been solved ...
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 / 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 / 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.
