Cells contain various specialized structures -- such as the nucleus, mitochondria or peroxisomes -- known as 'organelles'. Tracing their genesis and determining their structure is fundamental to understanding cell function and the pathologies linked to their dysfunction.

A new study reveals the detailed protein structure of the TAS2R14, a bitter taste receptor that allows us to perceive bitter taste. In addition to solving the structure of this taste receptor, the researchers were also able to determine where bitter-tasting substances bind to TAS2R14 and how they activate them. The findings may lead to the development of drugs that targeting taste receptors.

Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture resistant and highly biodegradable even in sea water. The development provides a platform for the industrial-scale, tunable production of a material that holds great potential for turning the plastic industry green.

Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.

Researchers have compiled a detailed catalogue of bacteria living in cancer metastases. Having analyzed over 4000 tumors, they shed light on the diversity of these co-inhabitants and how they might interact with cancer cells and their surroundings. For example, certain bacteria were linked to a worse response to immunotherapy. This study paves the way to a better understanding of how bacteria help or hinder cancer (therapy), and how we can use this for patients' advantage.

Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.

Multidrug-resistant bacterial infections that cannot be treated by any known antibiotics pose a serious global threat. A research team has now introduced a method for the development of novel antibiotics to fight resistant pathogens. The drugs are based on protein building blocks with fluorous lipid chains.
