Phys.org / Global study finds smaller fish and shifting food webs despite stable species numbers
Species numbers alone do not fully capture how ecosystems are changing. In a global study, scientists analyzed long-term data from nearly 15,000 marine and freshwater fish communities. They found that fish food webs have ...
Phys.org / AI tool observes solar active regions to advance warnings of space weather
New research by Southwest Research Institute (SwRI) and the National Science Foundation's National Center for Atmospheric Research (NSF-NCAR) has developed a new tool providing a first step toward the ability to forecast ...
Phys.org / Flickering glacial climate may have shaped early human evolution
Researchers have identified a "tipping point" about 2.7 million years ago when global climate conditions switched from being relatively warm and stable to cold and chaotic, as continental ice sheets expanded in the Northern ...
Phys.org / Obstacle or accelerator? How imperfections affect material strength
Imagine a material cracking—now imagine what happens if there are small inclusions in the material. Do they create an obstacle course for the crack to navigate, slowing it down? Or do they act as weak points, helping the ...
Phys.org / Social pressure forces baby clownfish to lose their bars faster, study shows
Growing up, you probably changed your style based on your social influences. It turns out, such pressures affect the appearance of young clownfish (anemonefish) too. A new study from the Okinawa Institute of Science and Technology ...
Phys.org / A new method to decode how DNA 'switches' control gene activity
DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning organism also requires precise instructions about when, where, and how much those components should ...
Phys.org / Uncovering evolution at the center of cell division
Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of chromosomes during cell division. Yet the striking diversity in centromere architecture—from large, ...
Phys.org / CT scans help detect ancient earthquakes in Hamilton Basin
In a world-first use of medical imaging technology, scientists have revealed the earthquake-generating potential of faults in the Hamilton and Hauraki areas. The study shows that hidden geological faults in Hamilton city ...
Phys.org / Female meiosis in plants can be directly observed with new method
A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female meiosis—the process by which germ cells are formed—in the model plant Arabidopsis thaliana. The FeM-ID ...
Phys.org / Transistor-like MXene membranes enhance ion separation
By applying voltage to electrically control a new "transistor" membrane, researchers at Lawrence Livermore National Laboratory (LLNL) achieved real-time tuning of ion separations—a capability previously thought impossible. ...
Phys.org / Mother-daughter bonds in red deer tied to survival and more surviving calves
Strong social networking plays an important role in human relationships. New research on female red deer shows that those bonds are also crucial for their reproductive success and survival. The study, which looked at more ...
Phys.org / Expands the genetic alphabet: Artificial DNA base pair uses halogen bonds to form stable structures
For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA building blocks are held together ...
