UCLA Biologists Uncover The Secrets Involved In Leaf Size, Shape
2013-10-31 14:36:02

Alan McStravick for redOrbit.com - Your Universe Online Trees, and more specifically, the leaves that adorn them, having predated human's foray into scientific learning, should harbor no mysteries at this point. However, nature continues to surprise us. Whether it is news of gold in eucalyptus leaves, as we learned last week with news out of Australia, or the simple yet profound truth of the math that governs internal leaf structure, human understanding continues to expand with the...

Recently, a mysterious seed fern, Lepidopteris baodensis sp. nov., dating to more than 251 million years ago (Ma), was discovered at the Baijiagou of Baode, Shanxi, China, from the Upper Permian Sunjiagou Formation. This discovery completely changed the understanding of the stratigraphic distribution of the genus Lepidopteris in China and promoted the taxonomic study of late Paleozoic plants. Since Schimper erected the genus Lepidopteris in 1869, its epidermal structure of subepidermal...

Plants breathe through stomata Plant leaves are protected from drying out by an airtight wax layer. They breathe and release water through microscopic pores called stomata. Every year 40% of atmospheric CO2 and twice the volume of water found in our atmosphere pass through these pores. This means that stomata are not only important for plant development but also for our climate! It's no surprise then that these pores appear to be strictly regulated by plants. Stomata react extremely...

New research sheds light on children´s game and provides insight into pollination Scientists have found that the distinctive glossiness of the buttercup flower (Ranunculus repens), which children like to shine under the chin to test whether their friends like butter, is related to its unique anatomical structure. Their findings were published today, 14 December, in the Royal Society journal Interface. The researchers discovered that the buttercup petal's unique bright and glossy...

The outer layer of the skin, called the epidermis, forms a critical physical and immunological wall that serves as the body's first line of defense against potentially harmful microorganisms. Most of the epidermis consists of cells called keratinocytes that build a mechanical barrier but also perform immune functions. Now, a new study published by Cell Press in the October issue of the journal Immunity provides evidence that stopping of a type of regulated cell death called "necroptosis" in...

How Key Genes Cooperate To Make Healthy Skin
2011-09-21 04:02:48

  Scientists from Berkeley Lab, the University of Bradford and Boston University discover a crucial connection in skin formation Skin is the body's armor, protecting us from disease agents, injury, excessive water loss, and cold and heat. Yet mutations in a single gene, the gene for the protein p63, cause numerous diseases and malformations of the uppermost layer of skin — the epidermis — and other tissues. In the epidermis, these range from skin cancers to dysplasias...

How plants space out the pores through which they breathe The way in which plants space out the pores through which they breathe depends on keeping a protein active during stem cell growth, according to John Innes Centre scientists. Plant pores, called stomata, are essential for life. When they evolved about 400 million years ago, they helped plants conquer the land. Plants absorb carbon dioxide through stomata and release oxygen and water vapour as part of the Earth's carbon and water...

In a study published in the journal Developmental Cell, Sarah Millar PhD, professor of Dermatology and Cell & Developmental Biology at the University of Pennsylvania School of Medicine, and colleagues demonstrate that a pair of enzymes called HDACs are critical to the proper formation of mammalian skin. The findings, Millar says, not only provide information about the molecular processes underlying skin development, they also suggest a potential anticancer strategy. "Inhibition of these...

Skin
2013-03-04 15:18:05

Skin is the outermost organ that protects and incases the tendons, ligaments, bones, muscles, etc. It is also the largest organ of the human body. Formation and Orientation Healthy skin consists of vitamins A, C, D and E, but in all skin, there are melanocytes which produce mesodermal cells. These cells allow for the absorption of UV rays. There are five main pigments that provide color in the skin’s many levels. Although not found in the skin, Oxyhemoglobin is found in the blood,...
