When is the best time to water during a heatwave?

...energy for growth. Plants also need water to carry nutrients from the soil to the growing cells. This water is drawn up to replace water lost through stomata – the breathing holes in leaves. These stomata are needed for gas exchange – carbon dioxide in, oxygen out – during photosynthesis. In high light levels, on sunny days, a lot of carbon dioxide is fixed to make...

...energy. However, even all this computer power is not enough; a good part of ChatGPT’s success lies in the use of humans. Even after the computerised training process was complete, ChatGPT often produced rambling, incoherent or irrelevant results. People were brought in to fine-tune its responses. They taught ChatGPT how to answer certain types of queries, to structure...

...energy). This area is referred to as the cell body. The final key structure is the axon. The axon consists of an area called the axon hillock which integrates all the different inputs across the dendrites and, if sufficient to excite the neuron, this region will initiate an electrical impulse, referred to as an action potential. The action potential will travel the length...

...energy they need to survive by oxidising sulfur. This group hadn’t been considered as organisms that could be viable on Mars but knowing they are capable of surviving under conditions that are very similar to Mars’s means we can ask questions about what might have happened to the chemistry of Mars if microbes like these had once lived there, giving us a potential...

Climate change: transitions to sustainability

...energy-intensive lifestyles (large cars, frequent air travel, energy-hungry appliances, etc.). European societies have followed a similar route, although they have not reached the same intensity of resource use. Although they would rarely put it in these words, many NGOs and commentators are absorbed by the question of whether a high-consumption lifestyle can be divorced...
