Plants that grow in hot environments display a very interesting adaptation to their surroundings. Over millions of years of evolution they have learned to elongate their stems in order to cool down their leaves, ensuring that nutrients continue to flow at optimal levels.
The discovery was made by researchers at the ... |

Scientists based at the Rockefeller University in New York say that mathematics and geometric patterns are present in the natural world in unexpected forms. They apparently connect structure to function in leaves, which may help explain why the latter are so beautiful.
It's important to note here that the human... |

Melissa Hopkins of the National Audubon Society says that throwing the leaves we gather after cleaning our backyards isn't the best option. Hopkins declared that 8 million tons of leaves end up in landfills every year.
Instead of considering them waste, we might consider them natural vitamins which can become... |

Scientists with the US Geological Survey (USGS) have calculated that leaves falling off trees in the autumn transfer as much mercury from the atmosphere to the environment as precipitations do.The work was focused on surveying the quantities of hazardous mercury that makes its way into the environment. According to r... |

Over the billions of years they had at their disposal, plants have evolved into a myriad of types, classes and families, each of them featuring their own unique traits. One of the most marked aspects that helps distinguish between various types of vegetation is the shape of their leaves. Throughout nature, we can obs... |

Many scientists around the world have over the past few years attempted to create an artificial leaf based directly on Mother Nature's design. The reason why such a device needs to be obtained is that it would basically convert sunlight into energy using the same process that all vegetation does, and namely phot... |

Scientists have been recently able to create a new type of material, that is capable of adhering to a large number of other surfaces, using nothing but a mechanism that was derived from the one the leaf beetle employs to stay attached to the leaf. In addition to being able to mimic nature in this regard, the investig... |

Researchers have recently been finally able to substantiate the claims that gardeners have been making for a long time, namely that you shouldn't water plants when it's hot outside. Those in the business of taking care of plants say that doing so may cause the leaves to get burnt, as the water droplets beha... |

Scientists at the Duke University have recently managed to establish why lotus leaves can stay dry naturally in the wild, but they seem to lose this ability while in the confined settings of research labs. The team, led by materials scientist Chuan-Hua Chen, determined that the plant essentially made use of the natur... |

It would appear that the same pollution particles that wreak havoc in our bodies also have adverse effects on plants. Scientists have recently discovered that emission particles that lay on tree leaves leave behind a small trace of magnetism in the plants. The phenomenon is more clearly visible in urban areas, where ... |

Spacecraft are very prone to malfunctions caused by external influences. Things as small as bacteria can jeopardize an entire mission, especially if they form biofilms atop various gears, or inside astronauts' living quarters. In an attempt to ensure that this doesn't happen, experts at NASA again turned to... |

While European poets and writers have for centuries written about the beauty of the yellow canopies in autumn, their American and Asian counterparts have mostly described the foliages as having a reddish hint to them. The difference is still visible today, and botanists set out to investigate precisely why that is so... |

According to a new study led by biologists from the University of Pennsylvania, tree leaves maintain a constant temperature during photosynthesis, regardless of the latitude they inhabit. Researchers used to believe that the temperature of a leaf while converting sunlight and carbon dioxide into nutrients would equal... |

Do you know which are the most abundant mammals on the tropical South American forest? Monkeys? Wrong! Sloths...Sloths are solitary and arboreal (tree dwellers) mammals. Today, there are 2 genera of sloths: three toed sloths (Bradypus) and two toed sloths (Choelepus), each one in its own family (thus, not so closely ... |

When did the trademark of Robin Hood appear?And how did the first woods look like? Scientists have now found complete fossils of the world's oldest forest, during the Devonian era, 385 million years ago. But this forest may have looked like young palm trees as it was made of slender trees about three stories ta... |
