An abrupt transition in the electrical resistance of graphite at 350 K could be a signature of superconductivity occurring well above room temperature (293 K). That is the claim of Pablo Esquinazi and ...

Using ultrafast, intensely bright pulses of X-rays scientists have obtained the first ever images at room temperature of photosystem II, a protein complex critical for photosynthesis and future ...

Winter wheat (Triticum aestivum L. cv Norin No. 61) was grown at 25°C until the third leaves reached about 10 cm in length and then at 15°C, 25°C, or 35°C until full development of the third leaves ...

Two species of Atriplex were grown under low temperature (8 C day/6 C night) and high temperature (28 C day/20 C night) regimes. The photosynthetic capacity of these plants was studied as a function ...

Plants and animals have many similarities when it comes to what they need to survive. Both need water and air. We often think of animals using oxygen and glucose for cellular respiration and producing ...

This story is part of Record High, a Grist series examining extreme heat and its impact on how — and where — we live. Around the world, leaves play a critical central role in staving off the worst ...

A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes. Using a complex cast of metal-studded pigments, proteins, enzymes, and co-enzymes, photosynthetic ...

Scientists have made a fundamental breakthrough in their attempts to replicate photosynthesis – the ability of plants to harvest the power of sunlight – in the hope of making unlimited amounts of ...

Carbon dioxide is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase. At some point, another factor may ...
