Tiny viruses that infect bacteria could one day help us tackle infections that antibiotics can no longer treat. But first, scientists need to understand how these viruses work, and artificial intelligence could provide them with a powerful way to do that.
When a dairy cow miscarries, a farmer loses far more than an unborn calf. Feed has been grown, land and water have been used, and greenhouse gases have been released during the cow's pregnancy, but milk production, a future animal and income are lost.
Many fascinating phases in quantum materials emerge when electrons, atoms and other microscopic components begin to act collectively. But these phases do not necessarily appear out of nowhere when a material crosses a transition temperature. Before long-range order develops, microscopic fluctuations can already be present.
NASA is planning to send three small rovers to the moon with a single instruction: Work out among yourselves how to explore a patch of ground.
Canine sarcoptic mange (scabies) is a skin condition in which microscopic mites (Sarcoptes scabiei) infest dogs' skin. The condition is contagious and zoonotic and can be difficult to detect. If left untreated, it can cause bleeding sores, malnutrition, emaciation and secondary bacterial infections that may eventually lead to a dog's death.
A new paper published in Physical Review Letters reveals that a leading dark matter candidate—the hypothetical "dark photon"—would not have heated the early universe as previously thought. The finding opens a vast region for experimental searches and could change the hunt for dark matter.
