It consists of a chain of blocks, each containing a list of transactions. Transactions are grouped into blocks through a process called mining, where participants in the network solve complex mathematical problems to add a new block to the chain. Once a block is added, it is cryptographically linked to the previous block, forming a secure and transparent chain of transactions. Blockchain technology provides a tamper-resistant and transparent record of transactions, eliminating the need for a central authority to validate and authenticate transactions. Cryptocurrencies: Cryptocurrencies are digital or virtual currencies that use cryptography for security and operate on decentralized networks, often based on blockchain technology.

Lovesick: Viruses have been caught leaving 'love bites' on each other for the first time ever! Viruses are notorious for infecting other organisms and ruthlessly taking advantage of their bodies to further their nutritional and reproductive goals. While this is a pretty well-documented phenomenon, these microbes seemed to have maintained a pretty good record within their own species, being careful not to latch onto each other. However, a new discovery turns this belief on its head after researchers found multiple instances of two viruses attached to each other in temporary matrimony, even discovering "love bites" on the viruses. Being neither dead nor alive, viruses ardently require a host to complete their life cycles. However, some viruses also need a "helper" virus to accomplish their goals, helping the "satellite" virus create protective shells or replicate its DNA as it burrows into the unsuspecting victim. While these viral relationships cert
