Medical Xpress / Programmable wound zipper adapts to complex skin injuries, improving healing in rats
Skin is our protective barrier from the outside world, and it is highly susceptible to damage. To prevent infection, restore protective skin cells, and reduce scarring, it is essential to quickly and robustly close a wound. ...
Medical Xpress / How gestational diabetes could affect a child's health before birth
Gestational diabetes is most commonly associated with temporary disturbances in glucose metabolism during pregnancy. However, growing evidence shows that its consequences may extend far beyond pregnancy itself—affecting a ...
Tech Xplore / Entirely new way of making espresso shakes up the coffee world
Researchers at UNSW Sydney have harnessed the power of ultrasonic sound waves to make espresso-strength coffee with room-temperature water, cutting energy use by up to 75%. That morning coffee kick from a shot of espresso ...
Phys.org / Human evolution was messy and gradual, not an abrupt revolution, argues archaeologist
It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt ...
Medical Xpress / Visual storytelling and sharing circles reveal community-led path to indigenous heart health
A novel study among Indigenous communities in Canada utilizing sharing circles as the primary method of qualitative data collection shows that heart health is shaped by emotional, spiritual, social, and systemic factors, ...
Tech Xplore / Russian satellites linked to mysterious GPS disruptions across several countries
Since 2019, GPS signals across Europe, Greenland and Canada have experienced a huge spike in sudden, widespread signal blackouts. These have resulted in disruptions and degraded performance in navigation systems that airplanes ...
Phys.org / Silver nanoparticles pave the way for precise DNA cutting and joining
DNA is composed of long chains that act as the blueprint for living organisms. In genetic engineering, scientists cut DNA at specific sites and join the resulting fragments to other DNA sequences, enabling applications such ...
Medical Xpress / CRISPR enzyme precisely detects and shreds DNA in cancer mutations once considered 'undruggable'
In 2020, Jennifer Doudna won the Nobel Prize in chemistry for her work on the CRISPR-Cas9 gene-editing technology that allows scientists to precisely modify DNA by cutting it at specific locations. Six years later, a new ...
Phys.org / People have an inherent preference for counterclockwise motion, study reveals
Researchers in Spain and Japan tested a broad range of pedestrians in varying group sizes to see whether there were any patterns in their turning behaviors, and what factors influenced them, if any. It turns out that the ...
Phys.org / Cosmic acceleration holds up as new analysis rebuts slowdown claim
Our universe's expansion is still accelerating despite recent claims suggesting otherwise, an international team of astrophysicists says.
Phys.org / Chimpanzees react negatively to unfairness, especially when close partners are nearby
Primates, including humans, are among the social animals living on Earth. Their survival relies heavily on cooperation with others, alliances, the sharing of resources and other social interactions.
