Could our streets be illuminated by the trees themselves someday? With the help of a mushroom, researchers make a breakthrough in engineering glow-in-the-dark plants. So, maybe someday is sooner than we think. Learn more about the science behind bioluminescent botanicals here. Continue reading Living Nightlights: Advances in creating glow-in-the-dark plants.
Study predicts that global warming will affect 60% of the world’s wheat-growing areas by 2100, even if the Paris Agreement’s targets are met. Damage would be global but developing countries and low-income regions likely to suffer most as rising temperatures affect global food production.
Continue reading Global warming threatens most of the world’s wheat production, and the Paris Agreement cannot prevent it
Using fossil fuels has led to climate change; however, trees can erase some damage. By maximizing forest coverage on Earth, scientists predict that the carbon dioxide levels in the atmosphere could be reduced by a quarter—back to levels from a hundred years ago.

By introducing a tool commonly used to study brain function into the leaves of plants, researchers at the University of Glasgow have developed a technique that shows promise in improving the efficiency of food production by controlling how quickly plants respond to changing conditions. Not only does this method produce a more desirable solution to improving efficiency than previous methods, it also highlights the importance of employing tools in non-conventional scenarios to produce clever solutions to complex problems. Continue reading Speedy Plants for Improving Food Production Efficiency
Plants grow in interesting ways. You may have noticed that your houseplants “lean” towards the window, seeking the sunlight. This movement towards light is called phototropism. Tropism is a general term referring to any instance of growth or movement of an organism in response to the environment. Vines display another kind of tropism known as thigmotropism, meaning they respond to touch. In this set of … Continue reading Vines
My name is Ian Hill. I am from Winston-Salem, North Carolina, where I was born and raised. My passion for biology began in the gardens of my family members. My grandmother was a passionate flower gardener, the head of a local garden club, and my dad grew some of the best tomatoes I have ever eaten. It wasn’t until my high school chemistry class that … Continue reading Ian Hill
Cross section of oak wood, showing every reason that made an oak tall and strong. The large pores are vessels that are responsible for transporting (more accurately, pumping/pushing) water from the root system to the tip of the tree. The densely packed purple dots are stained lignin in the cells walls. During early wood development, once lignin is deposited in the cell wall, these cells … Continue reading Oak Wood Cross Section
Tangential section of wood of Chinese holly. This is how it looks like when you do a cut that’s perpendicular to the radius of the stem. The vertical lines are vessels transporting water from roots to leaves, while the circles are clustered ray cells that function to transport fluids and nutrients radially and laterally (perpendicular to the long axis) within a woody stem. Contributed by … Continue reading Holly Wood Tangential Section
Microscope image of the epidermis of a spiderwort leaf with well-organized stomata in high density. Stomata (singular stoma) are like little mouths on the leaf surface, specialized in gas-exchange – CO2 enters a plant through them. The opening and closure of stomata are tightly controlled, because when stomata are open, water is escaping from the plant too. Therefore, each plant needs to find a delicate … Continue reading Monocot Leaf Epidermis
Lower leaf epidermis of the stonecrop plants showing puzzle shaped epidermal cells with scattered stomata. Stomata (singular: stoma) are like little mouths on the leaf surface, specialized in gas-exchange – CO2 enters a plant through them. The pairs of sausage-shaped cells, like the lips of these mouths, are “guard cells”, which guard the opening and closure of the stomata. In many flowering plants, the stomata … Continue reading Dicot Leaf Epidermis
