HIV is a very complicated virus, and we haven't succeeded in making a vaccine for it yet.Image credit:CanvasSince HIV first appeared, many things have changed. New medicines help people with HIV live well and stop them from spreading the virus. But to truly beat HIV, we need a vaccine.HIV is a big problem worldwide,...
'The Lawnmower' represents a groundbreaking achievement as the inaugural synthetic molecular motor capable of self-propulsion, deriving energy from its action of cutting through proteins, which are artificially generated by AI through DALL-E.The body uses tiny machines made of proteins to do important jobs. These machines help with things like cell division and moving around...
Credit: PexelsThe mystery of how living organism originated from non-living matter is still one of the most profound puzzles in science. Despite various theories, a definitive explanation remains elusive, which is not surprising given that these events took place three to four billion years ago in vastly different conditions on Earth.Justifying hypotheses with experimental...
The research indicates a new perspective on intra-person fingerprints. Credit: Unsplash.Fingerprint analysis, a cornerstone in forensic and security contexts, has long relied on fingerprint patterns' perceived uniqueness and permanence. However, groundbreaking research from Columbia University introduces a paradigm shift, challenging the conventional understanding of intra-person fingerprint distinctiveness.Challenging Conventional WisdomThe uniqueness of fingerprints, considered...
Radiant Snares of the Predatory Fungus Arthrobotrys Oligospora. Credit: Hung-Che Lin CC-BY 4.0Think fungi can't be carnivorous? Think again. Arthrobotrys oligospora, a worm-eating species of fungus discovered in 1850, has proven capable of sensing, trapping, and consuming small animals, shedding light on the molecular changes facilitating predatory behavior.Worms on the MenuWhile A. oligospora isn't the...
Scientists demonstrate that the potential origin of localized bone degradation in cholesteatomas involves bone-derived fibroblasts that produce a protein identified as activin A.Prolonged inflammation in the middle ear can lead to various complications impacting both hearing and balance for individuals. Among these issues, the emergence of cholesteatomas, and abnormal cell accumulations within the ear,...

By examining messenger RNAs involved in insulin synthesis in fruit...
A light micrograph of a section through the thorax of a mouse embryo, which shows left–right asymmetry. RIKEN researchers have discovered how cilia detect fluid flow, which eventually leads to this asymmetry.

Lake Gossenköllesee is located in the Tyrolean Alps. Credit: Christopher BellasThough human beings, along with other vertebrate and invertebrate organisms, do not photosynthesize, we're certainly the downstream beneficiaries of the life forms that do. Phototrophic organisms at the bottom of the food chain convert plentiful sunlight into the energy that ultimately powers all other...
