The discovery of how a critical enzyme 'hidden in nature's blueprint' works sheds new light on how cells control key processes in carbon fixation, a process fundamental for life on Earth. The discovery could help engineer climate resilient crops capable of sucking carbon dioxide from the atmosphere more efficiently, helping to produce more food in the process.

A research team has discovered how carboxysomes, carbon-fixing structures found in some bacteria and algae, work. The breakthrough could help scientists redesign and repurpose the structures to enable plants to convert sunlight into more energy, paving the way for improved photosynthesis efficiency, potentially increasing the global food supply and mitigating global warming.

The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.

A recent study led to the development of a powerful epigenetic editing technology. The system unlocks the ability to precisely program chromatin modifications at any specific position in the genome, to understand their causal role in transcription regulation. This innovative approach will help to investigate the role of chromatin modifications in many biological processes, and to program desired gene activity responses, which may prove useful in disease settings.

Tracking individual enzymes during the breakdown of cellulose for biofuel production has revealed how several roadblocks slow this process when using plant material that might otherwise go to waste. The research may lead to new ways to improve the breakdown process and make the non-edible parts of plants and other plant waste, such as forestry residue, a more competitive source of biofuels.

Fatty liver disease often leads to chronic liver inflammation and can even result in liver cancer. Scientists have now shown in mice that intermittent fasting on a 5:2 schedule can halt this development. The fasting regime reduces the development of liver cancer in mice with pre-existing liver inflammation. The researchers identified two proteins in liver cells that are jointly responsible for the protective effect of fasting. An approved drug can partially mimic this effect.

Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers have now determined how these structures work on a molecular level, as well as where and how they form.

Drones monitoring fields for weeds and robots targeting and treating crop diseases may sound like science fiction but is actually happening already, at least on some experimental farms. Researchers are working on driving forward the smart digitalization of agriculture and have now published a list of the research questions that will need to be tackled as a priority in the future.

Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
