Phys.org / Copper-64 isotope made easier: Recoil chemistry could lower medical imaging costs
The copper isotope Cu-64 plays an important role in medicine: It is used in imaging processes and also shows potential for cancer therapy. However, it does not occur naturally and must be produced artificially—a complex ...
Phys.org / Microplastics in oceans may distort carbon cycle understanding
The carbon cycle in our oceans is critical to the balance of life in ocean waters and for reducing carbon in the atmosphere, a significant process to curbing climate change or global warming.
Phys.org / X-ray spikes reveal electron beam size
While synchrotron radiation is often thought of as "stable," the electromagnetic field exhibits pronounced randomly fluctuating distributions both temporally and spatially. These fluctuations encode spatial information about ...
Phys.org / Social justice must guide global ecosystem restoration for lasting success, say researchers
Social justice must be at the heart of global restoration initiatives—and not "superficial" or "tokenistic"—if ecosystem degradation is to be addressed effectively, according to new research.
Phys.org / Visual system of butterflies changes with seasons, research reveals
The shift from warm summer to cool fall conditions can be stressful for many animals. Surviving each season requires a multitude of different physiological and behavioral traits that scientists are still working to understand.
Phys.org / Physicists provide key mass data for determining X-ray burst reaction rate
A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27. These precise measurements ...
Phys.org / Yeast cell factory converts methanol into L-lactate for biodegradable plastics
Methanol is an ideal feedstock for bio-manufacturing. Converting it into lactate, a monomer for biodegradable plastic, offers a promising strategy for addressing the challenge of white pollution. However, it remains difficult ...
Phys.org / Earlier ultra-relativistic freeze-out could revive a decades-old theory for dark matter
A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from Standard Model particles far earlier than previous theories had suggested.
Phys.org / CERN's ATLAS detects evidence for decay of Higgs boson into muon–antimuon pair
Although its existence had been theorized for decades, the Higgs boson was finally observed to exist in 2012 at the Large Hadron Collider (LHC) at CERN. Since then, it has continued to be heavily studied at the LHC. Now, ...
Phys.org / Silver nanoparticles built on viral biotemplate kill more bacteria and slow resistance rise
Antibiotics are no longer able to treat infections as effectively as they once did because many pathogens have developed resistance to these drugs. This phenomenon, known as antimicrobial resistance (AMR), claims over a million ...
Phys.org / A solid-state quantum processor based on nuclear spins
Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of outperforming classical systems on some tasks. Instead of storing information as bits, like classical computers, ...
Phys.org / Archaic humans were strategic and picky hunters, new study suggests
Extinct relatives of modern humans, like Neanderthals and Homo erectus, that lived in the Levant around 120,000 years ago, did not engage in mass hunting but preferred selective and strategic hunting of wild cattle. Scientists ...
