On the northeastern coast of Singapore, a lush, 27 m tall tree in Changi has a unique identity. Using a combination of techniques – population genetics and morphological evidence, researchers from Singapore, UK and the US discovered that this tree is the first recorded natural hybrid between two critically endangered local species - Sindora coriacea and Sindora echinocalyx. It is also the first instance of hybridisation in the genus Sindora. Named Sindora × changiensis, after the location it was discovered to be growing, carbon dating estimated this tree to be at least 226 years old! Conservation efforts are ongoing to propagate this hybrid and saplings from this tree have been planted islandwide in Singapore.

Scientists from the University of Florida have germinated seeds in the Moon's soil! 3 different samples of lunar soils or lunar regolith, collected during Apollo 11, 12 and 17 missions were used and Arabidopsis thaliana seeds were successfully germinated. However, it was observed that seedlings exhibited greater stress at the physical and genetic level, when grown on mature soils - Mature and young lunar soils have differerent compositions as the former is exposed to more cosmic winds. Although promising, further studies are required on how the addition of water and the presence of plants affect lunar soil minerology and importantly how to optimize lunar soils in order for plants to truly grow in situ on the moon.

Conventional paper is made using wood pulp in an energy intensive process, researchers at Nanyang Technological University (NTU) have developed a new type of paper using sunflower pollen grains. This patented pollen paper has been rendered non-allergenic, is recyclable and is less energy intensive to produce. High resolution colour images can be printed on pollen paper and “erased” in a much simpler process using a common alkaline reagent. This method is less damaging to the quality of the paper and has less negative impacts on the environment and human health. Pollen paper is also more versatile with potential uses in soft electronics, green sensors, and generators. While there are still issues such as scalability to explore, this study holds promise of a more environmentally sustainable paper.

A recent study on the forests of the world estimated that there are 73,000 tree species in the world. Of this, 9,200 tree species are new to science. This is 14 percent higher than the total known tree species worldwide. These undiscovered species likely have small populations and are limited in where they can be found in nature, making them vulnerable to climate change and deforestation. Approximately 40% of these undiscovered species are believed to be in South America, with the greatest diversity in the Amazon Basin and Andes-Amazon interface. In the face of our climate crisis, forest conservation should increasingly become an important priority especially for vulnerable and diversity hotspots around the world.

The impacts of climate change continue to pose a threat to our food systems. Alternative food crops like the drought resistant Enset (Ensete ventricosum) are more important than ever as they could potentially support our food security under climate change. The Enset, a relative of the Banana (Musa species), is a staple crop in Ethiopia cultivated for human food and medicine, animal feed and fiber. They are starchy in nature and are fermented before making into porridge or bread. Currently, Enset is an important part of the diet for about 20 million Ethiopians. Scientists predict that it can be successfully grown over a wider range of environmental and climate conditions in Africa, potentially supporting over 100 million Africans in the future. However, adoption of Enset as a crop outside of Africa has its hurdles, especially with other competing staple crops that are faster to harvest, have higher nutritional value and are less labour-intensive to process.
