How viruses move through insects for transmission of diseases
Viruses are master parasites that have adapted to infect many host species. Some viruses even use multiple hosts to spread their infections—such as arboviruses that use insects to move their infections to mammalian hosts like humans. Understanding.....»»
Bandwidth measurements show how pulsar signals distort as they move through space
A study that sheds new light on how pulsar signals—the spinning remnants of massive stars—distort as they travel through space, published in The Astrophysical Journal, was led by Dr. Sofia Sheikh, SETI Institute researcher, and performed by a mul.....»»

In a move to improve repairability across its product lineup, Apple will soon be selling speakers as an individual component, something that the company hasn’t done since the 2015 MacBook Pro model. more….....»»
New transformer-based AI model enhances precision in rice leaf disease detection
Rice is one of the world's most essential food crops, but its production is constantly threatened by leaf diseases caused by pathogens such as fungi, bacteria, and viruses. These diseases, which manifest as spots or blotches on leaves, can severely i.....»»
Wood ants that actively combat plant diseases could be used in organic apple orchards
The small industrious wood ant can do more than just build high nests in spruce forests. A newly published article in the journal Microbial Ecology reveals that ants combat a range of plant diseases, including those affecting apples. At the same time.....»»
Cyanobacterial circadian clock uses an AM radio-like mechanism to control cellular processes
Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission......»»
Scientists develop AI tool for personalized phage therapy as a targeted alternative to antibiotics
With the rapid development of antibiotics in the 1930s, phage therapy—using viruses known as bacteriophages or phages to tackle bacterial infections—fell into oblivion. But as the current rise in antibiotic resistance is making it increasingly di.....»»
