Phys.org / Quantum entanglement pushes optical clocks to new precision
By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze ...
Phys.org / Sometimes less is more: Messier nanoparticles may actually deliver drugs more effectively than tightly packed ones
The tiny fatty capsules that deliver COVID-19 mRNA vaccines into billions of arms may work better when they're a little disorganized. That's the surprising finding from researchers who developed a new way to examine these ...
Medical Xpress / New 'navigator' model aims to speed cell and gene therapies to patients
Despite innovative new research, many cell and gene therapies do not make it all the way to the patients. Researchers and clinicians in Lund have now presented a new model for cooperation that will shorten lead times and ...
Phys.org / A low-cost microscope to study living cells in zero gravity
As space agencies prepare for human missions to the moon and Mars, scientists need to understand how the absence of gravity affects living cells. Now, a team of researchers has built a rugged, affordable microscope that can ...
Phys.org / Ultra-stable lasers that rely on crystalline mirrors could advance next-generation clocks and navigation
Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep ...
Phys.org / Dense aquatic plants kept Spree River levels steady despite a near 50% flow drop
Researchers at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) have used long-term data from the Spree River to discover that aquatic plants can compensate for declining water levels in a drier climate. ...
Phys.org / Can Baltic Sea pollution cut fertilizer imports? A lab method suggests a path
The Baltic Sea is one of the world's most oxygen-depleted major bodies of water. The reason is excessive concentrations of phosphorus, an element essential for life—and an important ingredient in fertilizer. New research ...
Phys.org / Measuring chaos: Researchers quantify the quantum butterfly effect
For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen Li at the University of ...
Medical Xpress / Scientists discover why we know when to stop scratching an itch
When you scratch an itch, something tells your brain when to stop. That moment of relief, when scratching feels "enough," is not accidental. Scientists have now identified a key molecular and neural mechanism behind this ...
Tech Xplore / How eyes affect our perception of a humanoid robot's mind
Eyes are said to be the mirror of the soul. Eyes and gaze direction guide attention, evoke emotions and activate the brain's social perception mechanisms. Researchers at Tampere University and the University of Bremen conducted ...
Phys.org / Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein ...
Phys.org / Thousands of paywalled research papers could be freed with this simple fix
Publicly funded research underpins much of daily life, from policy decisions to innovation and public debate. When research remains inaccessible, its value is diminished. Australia has made real progress on open access to ...
