Researchers have developed a method that has now mapped several billion trees and their carbon uptake in Africa's Sahel. In the future, the method could be used to monitor whether climate credit purchases have a positive effect on the number of trees and whether nature restoration is working.

After more than 30 years, botanists have rediscovered Thismia kobensis, a type of mysterious-looking rare plant commonly referred to as 'fairy lanterns'. Thismia kobensis was presumed extinct and the surprise rediscovery of this Japanese variety has illuminated hidden aspects of fairy lanterns that have puzzled and fascinated botanists for centuries.

Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles.

Plants can move in ways that might surprise you. Some of them even show 'sleep movements,' folding or raising their leaves each night before opening them again the next day. Now, researchers offer convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years ago.

Growing wheat in drought conditions may be easier in the future. Researchers found the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies.

To reduce biodiversity loss in agricultural landscapes, more sustainable and environmentally friendly agricultural practices are needed. A research team has investigated how ecosystem services such as pollination could be improved in macadamia plantations. The scientists showed that a certain design of plantations -- for instance, how the rows of trees are arranged, the varieties, and the integration of semi-natural habitats in and around the plantations -- can increase the pollination performance of bees.

Although many measures are in place to prevent contamination, pollutants, such as mercury and lead, can still end up in the environment. Sensing them often requires complicated processes, but what if you could detect them with the tap of a fingertip? Researchers have now developed a self-powered nanosensor that can discover small amounts of mercury ions and immediately report the result.

Researchers have added components of plant chloroplasts to bacteria. This feat, 50 years in the making, allows them to analyze the proteins in greater detail in order to improve Rubisco, and eventually photosynthesis.

An international research team demonstrates that the European spruce bark beetle (Ips typographus) uses volatile fungal metabolites of plant defense substances as important chemical signals in their attack on spruce trees. The researchers also show that the insects have olfactory sensory neurons specialized for detecting these volatile compounds. The fungal metabolites likely provide important clues to the beetles about the presence of beneficial fungi, the defense status of the trees, and the population density of their conspecifics. The study highlights the importance of chemical communication in maintaining symbiosis between bark beetles and their fungal partners.

The redox regulation mechanism responsible for efficient production of ATP under varying light conditions in photosynthetic organisms has now been unveiled. Researchers investigated the enzyme responsible for this mechanism and uncovered how the amino acid sequences present in the enzyme regulate ATP production. Their findings provide valuable insights into the process of photosynthesis and the ability to adapt to changing metabolic conditions.

Climate change is aggravating the impact of droughts -- one of the factors that only affect plant physiology -- on all plant ecosystems worldwide. Although new tools have been developed to detect and assess drought stress in plants -- transcriptomic or metabolomic technologies, etc. -- they are still difficult to apply in natural ecosystems, especially in remote areas and developing countries.

Metabolic engineering is a field of plant biotechnology that seeks to genetically modify plant metabolic pathways to generate plant varieties with improved health benefits. Recently, scientists engineered potato and tomato plants to express the plant pigment betalain -- found only in Caryophyllales and higher fungi. They found that while betalain-tomatoes conferred anti-inflammatory effects against macrophages and murine colitis, betalain-potatoes showed no such effects.

Scientists have for the first time constructed the reference genome for the source of the popular fiber supplement, psyllium husk, which could boost supplies of the versatile plant-derived product.

In some years, rice blast disease destroys more than one quarter of the harvest worldwide. But it's hard to fight with current methods. Researchers have now discovered how the fungus breeches the tough skin of the rice leaf and determined the structure of the enzyme secreted to puncture the leaf. They're now searching for chemical blockers that would work as a spray-on fungicide for rice and other crops.

Traditionally, it has been assumed that cultivating food leads to a loss of biodiversity and negative impacts on an ecosystem. A new study defies this assumption, showing that community gardens and urban farms positively affect biodiversity, local ecosystems and the well-being of humans that work in them.
