Phys.org / Endometrial mRNA therapy to treat infertility finds early success
Researchers from the Wilmer Eye Institute, Johns Hopkins Medicine Center for Nanomedicine—which designs nanotechnology-based platforms for clinical translation across specialties—developed a strategy for delivering therapeutic ...
Phys.org / Meta-study reveals mechanisms of animals' adaptations to cope with climate change
Climate change has a wide range of effects on wildlife. It affects seasonal migration, reproduction times, body size and mass, and disrupts ecological processes, thereby posing challenges for the populations of some species. ...
Phys.org / COVID-era trick could transform drug and chemical discovery
Laboratories turned to a smart workaround when COVID‑19 testing kits became scarce in 2020. They mixed samples from several patients and ran a single test. If the test came back negative, everyone in it was cleared at once. ...
Phys.org / New structural insights reveal how human respiratory chain complexes assemble
A new study shows how one of the cell's most important energy-producing machines is built. Researchers at Karolinska Institutet have mapped late steps in the formation of the human respirasome, a large protein assembly that ...
Phys.org / North Atlantic deep waters show slower renewal as ocean ventilation weakens
The ocean is continuously ventilated when surface waters sink and transport, for example, oxygen and carbon to greater depths. The efficiency of this process can be estimated using the so-called water age, which describes ...
Phys.org / Market freedom may impact homicide rates
Countries with a stronger market orientation may experience lower rates of homicide, according to a new study from the University of Georgia.
Phys.org / Scientists uncover hidden 'winter memory' inside plants
Scientists have developed a powerful new microscope that reveals, for the first time, how plants store a 'memory' of winter deep inside their cells.
Medical Xpress / Helping hands: Research team develops brace to reduce tremors
UBC Okanagan researchers have advanced their work on developing a noninvasive, accessible way to reduce uncontrolled hand tremors. In their newly published study, the team has demonstrated how a new wearable device may reduce ...
Phys.org / Imaging technique captures ultrafast electron and atom dynamics in chemical reactions
During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical products. This process entails the movement of both electrons (i.e., negatively charged particles) and ...
Phys.org / Critique highlights challenges in measuring Yellowstone aspen ecosystem response to wolf reintroduction
A critique from a team led by Utah State University ecologist Dan MacNulty and published in Forest Ecology and Management has prompted a formal correction to a high-profile study on aspen recovery while raising broader questions ...
