Scientists have developed a new technique for rejuvenating skin cells. This technique has allowed researchers to rewind the cellular biological clock by around 30 years according to molecular measures, significantly longer than previous reprogramming methods. The partially rejuvenated cells showed signs of behaving more like youthful cells in experiments simulating a […]

Ocean water samples collected around the world have yielded a treasure trove of new data about RNA viruses, expanding ecological research possibilities and reshaping our understanding of how these small but significant submicroscopic particles evolved.

A study of orb weaver spiders finds their massive webs also act as auditory arrays that capture sounds, possibly giving spiders advanced warning of incoming prey or predators.

In experiments, the researchers found the spiders turned, crouched or flattened out in response to sounds, behaviors that spiders have been known to […]

New biological tools provide new techniques to probe fundamental biological processes. Here we describe the burgeoning field of proteolysis-targeting chimeras (PROTACs), which are capable of modulating protein concentrations at a post-translational level by co-opting the ubiquitin-proteasome system. We describe the PROTAC technology and its application to drug […]

Researchers have shown a new compound delivered in a nasal spray is highly effective in preventing and treating COVID-19 caused by the Delta variant in mice. The researchers believe this is the first treatment of its kind proven to be effective against all COVID-19 variants of concern reported to date, including […]

Over the past few years, biogenic methods for designing silver nanocomposites are in limelight due to their ability to generate semi-healthcare and para-pharmaceutical consumer goods. The present study reports the eco-friendly synthesis of silver nanoparticles from the hitherto unexplored mucus of territorial snail Achatina fulica by the facile, clean and easily […]

A new study has found the tiny structures made up of mushroom-shaped micropillars topped with ultra-small pores allow lizards to quickly detach their tails when needed.
Microscopy images showed that each lizard tail muscle break-off point consists of highly dense mushroom-shaped micropillars with ultra-small nanopores dotting […]

Abstract: Synthetic carriers such as polymer and lipid particles often struggle to meet clinical expectations. Natural particulates — that range from pathogens to mammalian cells — are therefore worth examining in more depth, as they are highly optimized for their specific functions in vivo and possess features that are often desired […]

In recent decades, synthetic plastic polymers have been the most practical and economical solution for packaging applications due to their low cost, availability, excellent optical, mechanical and barrier properties and resistance against water. However, most of the plastics used for packaging are hardly biodegradable. With a view to a circular economy, […]
