Ancient Crater Lakes Rewrite Saharan Climate History, And Possibly Civilization’s Origins
The findings suggest the Sahara had an extra source of rain that kept part of it habitable until surprisingly recently.
Sound Waves Unlock a New Path to Practical Quantum Computing
Caltech scientists have created a hybrid quantum memory that converts electrical information into sound, allowing quantum states to last 30 times longer than in standard superconducting systems.
Their mechanical oscillator, like a microscopic tuning fork, could pave the way for scalable and reliable quantum storage.
Quantum Bits vs. Classical Bits.
Gut Neurons Direct Immune Healing After Inflammation
Their previous work revealed that ILC2s are a major source of a tissue-healing growth factor called amphiregulin and have the capacity to receive neuronal signals that modulate their function and can impact disease progression and recovery.
In the new study, they demonstrated that the tissue-protective function of ILC2s depends on production of a molecule called adrenomedullin 2 (ADM2) from the enteric nervous system; administering the molecule expanded this group of ILC2s and provided therapeutic benefit in a preclinical model of inflammatory bowel disease, whereas loss of ADM2 signaling exacerbated disease due to the lack of these protective cells.
First Insect Proven To Use Milky Way For Orientation Uses Its Superpower To Push Big Balls Of Poop
The sky at night. It inspires awe. It inspires thoughts of an existential nature: Who are we? Why are we here? And, perhaps most importantly of all, in which direction should I roll this big ball of shit? That is, if you’re a dung beetle.
“African ball-rolling dung beetles exploit the [Sun], the [Moon], and the celestial polarization pattern to move along straight paths, away from the intense competition at the dung pile,” wrote the study authors. “Even on clear moonless nights, many beetles still manage to orientate along straight paths. This led us to hypothesize that dung beetles exploit the starry sky for orientation, a feat that has, to our knowledge, never been demonstrated in an insect.”
