A new toolbox helps characterize internal ribosome entry sites within cells
Credit: EMBO Journal (2025). doi:10.1038/s44318-025-00404-5 Recently, beans, recognized as activity regulators of gene expression at the protein biosynthetic level, have ribosomes (one of the oldest molecular machines in evolutionary terms). This is an important process of cell development and function where genetic information is converted to proteins. The final step in which information encoded with messenger RNA (mRNA) is transferred…

Thorny skates come in sizes of “snacks” and “party”: after a century of speculation, scientists know why now
Thorny skates don’t move much. According to Kneebone, individuals could remain in the 50-kilometer area for nine years. Credit: Florida Museum of Natural History, Christenglas When Jeff Neebone was a university student in 2002, his research included marine mysteries that have been baffling curious scientists for the past 20 years. The mystery involved thorny skates in the North Atlantic. In…

In the summer of 2020, researchers at the University of Manitoba installed a time-lapse camera overlooking the mouth of the Churchill River. The goal of their research was to understand the interaction between beluga whales and marine vessels. But it was unexpected that they filmed. A group of bowhead…

The oldest human face in Western Europe discovered in Spain
There is a new fossil (left fragment) found in Atapoelka in Spain, where there is a reconstruction of the mirror on the right using imaging techniques. Credit: Cenieh/Nature Researchers at Atapuerca Archaeological Sites in Burgos, Spain have just broken their own records by discovering the oldest human beings in Western Europe for the third time. The team first excavated a…

The hidden friendly side of tobacco: how can you use controversial plants in good condition?
Credit: Pixabay/CC0 Public Domain Cigarettes kill 8 million people worldwide each year, but imagine if they can be used to make medicines. The idea is not unheard of. Tobacco has been used as a herbal medicine in the past. But in the age of genetic engineering, tobacco may be the future of pharmaceutical production on the planet and beyond. European…

Sharks die at an incredible speed, mainly for fishing. Retention bans may be helpful
Sharks are often observed with hooks, scars, or other evidence of encounters with fishermen. This Caribbean reef shark was found in the Bahamas, a wire leader hanging from its mouth. Since 2011, catching sharks in the Bahamas has been illegal. Credit: Shane Gloss Despite the fear they may inspire humans, sharks have far more reasons to fear us. Nearly a…

Snake’s Secret Language of UV Rays: Predator Evasion and Camouflage Hidden World
Visible (color) and UV (grayscale) photographs of three pit viper species with wide range of UV reflectance. From top to bottom, the species are the prairie rattlesnake, the western diamondback rattlesnake, and the two-stripe forest pit viper (the green one). All of these snakes are closely related species, but exhibit a wide range of UV reflectance. The white circles in…

SuperComputer draws molecular blueprints to repair damaged DNA
The Summit supercomputer revealed how the damaged strands of DNA are surgically repaired by a molecular pathway called nucleotide excision repair (NER). The protein components of the NER can change shape and perform different repair functions on broken strands of DNA (blue and red helix). Credit: Tanmoypole, Georgia State University Sunburn and aging skin are the obvious effects of exposure…

Computational models enhance protein kinase target predictions for treatment
Success rates of single target RF models in predicting kinase inhibitory activity of selected eight compounds. Success rates represent the percentage of correctly predicted kinase activity obtained for each compound for 20 experimentally tested targets. Credit: International Journal of Molecular Sciences (2025). doi:10.3390/ijms26052157 Research on protein kinases provides an opportunity to explore molecular targets in the body to treat diseases…
