Measuring the tRNA world February 26, 2021

Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but measuring the amount of each tRNA in cells has been limited by technical challenges. Researchers have now overcome these limitations with mim-tRNAseq, a method that […]

Pioneering prehistoric landscape reconstruction reveals early dinosaurs lived on tropical islands February 26, 2021

A new study using leading edge technology has shed surprising light on the ancient habitat where some of the first dinosaurs roamed in the UK around 200 million years ago.

Under climate stress, human innovation set stage for population surge February 26, 2021

Aridification in the central plains of China during the early Bronze Age did not cause population collapse, a result that highlights the importance of social resilience to climate change. Instead of a collapse amid dry conditions, development of agriculture and increasingly complex human social structures set the stage for a dramatic increase in human population […]

Pesticide imidacloprid threatens future for key pollinator February 26, 2021

An insecticide used to control pest infestations on squash and pumpkins significantly hinders the reproduction of ground-nesting bees -- valuable pollinators for many food crops, new research has revealed.

Maternal instincts lead to social life of bees February 26, 2021

The maternal care of offspring is one of the behavioral drivers that has led some bee species to have an ever-expanding social life over the history of evolution, new research has found. By virtue of being in a social group the genome itself may respond by selecting more social, rather than non-social genes. The behavior […]

Targeted spraying to prevent malaria in low-transmission setting halves cost of current practice February 26, 2021

Furthermore, the targeted Indoor Residual Spraying (IRS) intervention was safe, less costly, and more cost-effective compared with standard 'blanket' IRS, meaning savings could potentially be reallocated to other malaria control and elimination activities.

Dinosaur species: 'Everyone's unique' February 26, 2021

'Everyone's unique' is a popular maxim. All people are equal, but there are of course individual differences. This was no different with dinosaurs. A study has now revealed that the variability of Plateosaurus trossingensis was much greater than previously assumed. The paleontologists examined a total of 14 complete skulls of this species, eight of which […]
