DNA is only one among millions of possible genetic molecules

Biology encodes information in DNA and RNA, which are complex molecules finely tuned to their functions. But are they the only way to store hereditary molecular information? Some scientists believe life as we know it could ...

New understanding of antibiotic synthesis

Researchers at McGill University's Faculty of Medicine have made important strides in understanding the functioning of enzymes that play an integral role in the production of antibiotics and other therapeutics. Their findings ...

From cone snail venom to pain relief

Conotoxins are bioactive peptides found in the venom that marine cone snails produce for prey capture and defense. They are used as pharmacological tools to study pain signalling and have the potential to become a new class ...

Synthetic compound provides fast screening for potential drugs

A simple assay may benefit drug discovery for treating diabetes, Parkinson's, and Alzheimers disease, as well as studies of functional food and endocrine disruptor report researchers at Okayama University in the Journal of ...

Wood-based fiber captures hormones from wastewater

VTT and Aalto University have developed a wood-based cellulose fiber yarn that is an affordable solution for capturing pharmaceutical substances—especially ethinylestradiol in contraceptive pills—that would otherwise ...

Fluorescent probes offer fuller view of drug delivery in cells

Selecting the most effective molecules for drug delivery is often a trial-and-error process, but Cornell engineers are providing some precision thanks to a technique that reveals the performance of those molecules inside ...

Sustainability of new creosote alternative confirmed

A recently published study has confirmed the sustainability credentials of a new biobased alternative to creosote that is being developed in the Bio4Products project. The use of wood modification based on pyrolysis oil was ...

Malaria pathogen under the X-ray microscope

Malaria is one of the most threatening infectious diseases in the world. An international team has now been able to investigate malaria pathogens in red blood cells in vivo using the BESSY II X-ray microscope and the ALBA ...

Turning a dangerous toxin into a biosensor

Some types of bacteria have the ability to punch holes into other cells and kill them. They do this by releasing specialized proteins called "pore-forming toxins" (PFTs) that latch onto the cell's membrane and form a tube-like ...
