Phys.org / The 'Great Unified Microscope' can see both micro and nanoscale structures
Researchers at the University of Tokyo have built a microscope that can detect a signal over an intensity range 14 times wider than conventional microscopes. Moreover, the observations are made label-free, that is, without ...
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 ...
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 / Chang'e-6 samples reveal first evidence of impact-formed hematite and maghemite on the moon
A joint research team from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) and Shandong University has for the first time identified crystalline hematite (α-Fe2O3) and maghemite (γ-Fe2O3) formed ...
Phys.org / Bacterial enzyme uses vitamin C to neutralize immune defenses, study finds
Throughout evolution, pathogenic microorganisms, such as bacteria, viruses, and fungi, have developed sophisticated defense strategies to survive and multiply in the hostile environment of their hosts. These mechanisms increase ...
Phys.org / Shocked galaxy clusters: Unraveling the mysteries of radio relics
Galaxy clusters are the largest gravitationally bound structures in the universe, with each containing hundreds or even thousands of galaxies. When two of these giants collide, they send powerful shock waves through one another, ...
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 / Even moderate heat waves can depress sea urchin reproduction along the Pacific coast
Biologists thought that marine heat waves lowered urchin reproduction only at lethal temperatures. A new study shows reproductive shutdown even earlier.
Phys.org / Fighting poverty may require cultural wisdom, not just cash
Most poverty-fighting efforts focus on meeting basic material needs, such as food and shelter. But this overlooks the psychological and cultural factors that shape how people take action in their lives.
Phys.org / HD⁺ ions cooled to 18 mK yield most precise vibrational-rotational spectra to date
A research team from the Innovation Academy for Precision Measurement Science and Technology (APM) of the Chinese Academy of Sciences has made significant progress in precisely measuring the vibrational-rotational spectra ...
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 / 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.
