Medical Xpress / Nerve growth factor alone triggers osteoarthritis-like joint changes in healthy mice
Nerve growth factor (NGF) is a specialized protein, also called a neurotrophin, that is critical for the development and survival of nerves responsible for our senses and the body's fight-or-flight response. While the presence ...
Medical Xpress / Low-frequency wireless sensor tracks artery stiffening in real time with less interference
Wireless sensors used in wearable smart devices and medical equipment must be capable of detecting minute changes while maintaining high operational stability. However, existing technologies often utilize excessively high ...
Phys.org / Between eternal night and day, the faces of two cousins of Earth
An international team including the University of Bern (UNIBE) and the University of Geneva (UNIGE), members of the National Center of Competence in Research PlanetS, has succeeded in mapping the climate of rocky exoplanets ...
Phys.org / Video shows that sunbirds suck, while hummingbirds don't
Two unrelated groups of nectar eaters, hummingbirds and sunbirds, have evolved different techniques to slurp the sweet liquid from flowers. The tongue suctioning employed by sunbirds is unique among vertebrates, according ...
Phys.org / Global warming is changing the hatching of bees and wasps
A large-scale experiment shows that warmth brings bees and wasps out of hibernation earlier—leaving some of them with poorer starting conditions. This is particularly true for species in cooler regions that emerge during ...
Phys.org / Math model reveals how life may have switched on from Earth's primordial soup
Isolating the first spark of life on Earth is a matter of biology, geology, and chemistry—but it's also an amazing math problem. At least, that's how Varun Varanasi viewed it when he was a Yale undergraduate. The question, ...
Phys.org / Unlocking unusual superconductivity in a lightweight element
Superconductors—materials that can conduct electricity without energy loss—are crucial for next-generation high-efficiency, ultrafast electronics. However, most superconductors share a critical limitation: they lose their ...
Phys.org / New research on cellular redox reactions sheds light on the path of neurodegenerative diseases
The mechanics of the onset of cancer or neurodegenerative disorders like Alzheimer's disease or ALS remain a mystery. Scientists associate these diseases with an increase in unstable molecules called reactive oxygen species ...
Phys.org / Quantum sensors get a precision boost as 2D defects reveal their hidden timing
A key factor for the performance of sensors is the speed at which the system returns to its initial state after a disturbance or measurement, similar to the taring of a balance. In the quantum sensor under investigation, ...
Phys.org / Ancient Korean DNA reveals marriages between closely related individuals
DNA studies of 1,500-year-old skeletons have revealed that ancient Koreans lived in tightly knit family networks where marrying close relatives was common in some cases, from powerful elites to individuals chosen for human ...
Phys.org / Space telescopes track nearby quasar's dramatic X-ray state transition
By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed ...
Phys.org / Plants use a protein-tagging complex to control stress survival, study finds
A specific cellular mechanism regulates the protein balance of plants, thereby influencing how they respond to environmental stress. An international research team led by Dr. Markus Wirtz at the Center for Organismal Studies ...
