Tech Xplore / A smelly snapshot of the current state of electronic noses for robots
Robots are getting better at sniffing out smells thanks to improvements in electronic noses (e-noses). A comprehensive review of the state of robot olfaction, published in the journal npj Robotics, has surveyed recent advances ...
Phys.org / Mapping cell development with mathematics-informed machine learning
The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
Phys.org / Satellite study reveals 24.2 billion ton annual groundwater loss in High Mountain Asia
A recent satellite-based study has uncovered alarming declines in groundwater storage across High Mountain Asia (HMA), widely known as the "Asian Water Tower." This critical water source, which sustains agricultural irrigation, ...
Phys.org / Sprint or marathon? Aging muscle stem cells shift from rapid repair to long-term survival
Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher levels of a protein ...
Phys.org / Lab study suggests longer waves fracture floating ice sheets at lower stress
When waves are moving across ice-covered seas, they can cause sheets of ice to bend and ultimately break. Understanding the processes underlying these wave-induced ice fractures and predicting when they will occur could help ...
Phys.org / Spider spinneret evolution: How a genome duplication event 438 million years ago set the stage
Scientists have uncovered a 400-million-year-old genetic secret that gave spiders the ability to produce silk and weave their webs. Spiders didn't begin their journey on Earth in the same way as they are known today. Arthropods ...
Phys.org / Single-cell microdevice isolates and profiles extracellular vesicles over weeks
Extracellular vesicles and particles are central to how cells communicate, especially in cancer, where they help shape metastasis and treatment resistance. However, most existing methods analyze vesicles in bulk, masking ...
Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans
Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...
Medical Xpress / Psychosis rates are increasing in more recent generations, large-scale Canadian study finds
People born more recently are being diagnosed with psychotic disorders (e.g., schizophrenia) more often and at younger ages than people born earlier, suggests a large study of more than 12 million people in Ontario, published ...
Phys.org / Fossil hunters uncover 132-million-year-old dinosaur footprints on South Africa's coast
Southern Africa is world renowned for its fossil record of creatures that lived in the very distant past, including dinosaurs. But, about 182 million years ago, a huge eruption of lava covered much of the landscape (the inland ...
Phys.org / A world-first mouse that makes gene activity visible
DNA can be thought of as a vast library that stores all genetic information. Cells do not use this information all at once. Instead, they copy only the necessary parts into RNA, which is then used to produce proteins—the ...
Phys.org / New species of ladybird beetle discovered on university campus in Japan
University campuses are often places of learning and discovery, but rarely do researchers find a new species living right on their doorstep. However, that is exactly what happened when a research team from Kyushu University ...
