Phys.org / How cells preserve mitochondrial DNA quality across generations
Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The study, published in ...
Phys.org / Offsetting blue carbon benefits: Mangrove tree stems identified as previously underestimated methane source
Mangrove ecosystems rank among the most efficient "blue carbon" systems on Earth, capable of absorbing and storing vast quantities of atmospheric carbon dioxide (CO2). However, mangroves also release methane (CH4), a potent ...
Phys.org / Reading a quantum clock costs more energy than running it, study finds
A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of measurement itself. In a study published in Physical Review Letters, scientists demonstrate that the ...
Phys.org / Mosquito reproduction may hinge on E93 gene that links blood meals to energy use
Mosquito-borne diseases, including dengue, Zika, and yellow fever, continue to pose a significant global health threat, infecting millions of people annually. Yet current control efforts face growing challenges, driven by ...
Phys.org / Dark-colored lichens cause underestimation in Antarctic vegetation mapping, study reveals
A research team from the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS), in collaboration with Argentina's Center for Advanced Studies in Earth Sciences and Biodiversity (CADIC-CONICET), ...
Phys.org / How plants decide when to flower: Scientists discover a phosphorus-responsive switch
Phosphorus, a key ingredient in fertilizers, is running out. The world's food systems depend on phosphorus mined from limited reserves, yet much of what is applied to fields washes away, leaving soils increasingly depleted. ...
Phys.org / ALMA resolves close companion orbiting giant red star
Close companions can influence stellar evolution in many ways. While some companions can be detected around young stellar objects, direct observational evidence of companions around asymptotic giant branch (AGB) stars or ...
Phys.org / Simultaneous imaging of intracellular DNA and RNA using harmless light
NIMS, in collaboration with Nagoya University, Gifu University, and the University of Adelaide, has developed a method for simultaneously imaging DNA and RNA inside cells using harmless infrared to near-infrared light.
Phys.org / College degree still offers strong financial returns despite student loan debt, study finds
Even after factoring in student loan payments, completing a college degree continues to pay off, according to new research from Washington University in St. Louis' Center for Social Development (CSD) at the Brown School.
Phys.org / Smarter magpies linked to social network connections
The social interactions Western Australian magpies experience in their first year of life affects their intelligence, according to a new study.
Phys.org / Controlling triple quantum dots in a zinc oxide semiconductor
Quantum computers have the potential to solve certain calculations exponentially faster than a classic computer could, but more research is desperately needed to make their practical use a reality. Quantum computers use a ...
Phys.org / Adaptive tracking theory of molecular evolution challenges mutation neutrality
For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary enough to slip through the ...
