A new study finds just 6% of clinical trials used to approve new drugs in the U.S. reflect the country’s racial and ethnic makeup, with an increasing trend of trials underrepresenting Black and Hispanic individuals.

Researchers have found a way to control protein levels inside different tissues of a whole, living animal for the first time. The technological advance works while a nematode worm continues to live normally: eating, moving and growing as the system quietly adjusts protein levels inside the tissues of its body. The study paves the way for designing completely new experiments that were impossible to carry out with current techniques and unravel the molecular underpinnings of whole-body processes like ageing.

Researchers at Stockholm University have uncovered surprising insights into a large, previously unstudied group of bacteria, some originating from Swedish lakes. The findings reveal how bacterial lifecycles have evolved and even reversed their complexity over time. The study is published in Nature Communications.

A team led by Prof Susann Wicke from the Institute for Evolution and Biodiversity at the University of Münster has shown that certain parasitic plants activate their haustoria independently of the host plant. This strategy increases their ability to successfully infest the host.

A team from the Institute of Integrative Cell Biology and Physiology at the University of Münster has now shown that the talin protein plays a central and evolutionarily conserved role in cell adhesion.

Mosasaurs, giant marine reptiles that existed more than 66 million years ago, lived not only in the sea but also in rivers. This is shown by new research based on analyses of a mosasaur tooth found in North Dakota and believed to belong to an animal that could reach a length of 11 metres. The study, conducted by an international team of researchers led from Uppsala University, shows that mosasaurs adapted to riverine environments in the final million years before they became extinct.

Researchers at Osaka Metropolitan University have successfully cultured canine iPS cells in a medium without using components of human origin.

Researchers from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) have uncovered the long-elusive biosynthetic pathway of glycitein, a key soybean isoflavonoid. They also revealed how its production determines the plant's resistance to Phytophthora sojae.

New research reveals a link between rising temperatures and changes in polar bear DNA, which may be helping them adapt and survive in increasingly challenging environments. 

The study by scientists at the University of East Anglia (UEA) discovered that some genes related to heat-stress, aging and metabolism are behaving differently in polar bears living in southeastern Greenland, suggesting they might be adjusting to their warmer conditions. 

The finding suggests that these genes play a key role in how different polar bear populations are adapting or evolving in response to their changing local climates and diets.
