Is The Key To Immortality Held by Palm Trees
2012-12-19 14:01:56

American Journal of Botany Recent review reveals unique cellular structure and function that may contribute to their long life-span For centuries, humans have been exploring, researching, and, in some cases, discovering how to stave off life-threatening diseases, increase life spans, and obtain immortality. Biologists, doctors, spiritual gurus, and even explorers have pursued these quests–one of the most well-known examples being the legendary search by Ponce de León...

Future wood production quality tied to cambial function and regulation As large organisms, trees face some remarkable challenges, particularly regarding long-distance transport and communication. In addition to moving water and nutrients from their roots to their leaves, they must also integrate cell-to-cell communication over large areas. Furthermore, in order to function as a single, cohesive organism they must be able to effectively and efficiently send vital substances–such as...

Algae Held Captive And Their Genes Stolen In Crime Of Evolution
2012-11-28 15:38:41

University of Melbourne Microscopic animals held algae captive and stole their genes for energy production, thereby evolving into a new and more powerful species many millions of years ago reveals a new study published today in the journal Nature. The results reveal a 'missing link' in evolution because the tiny animal thieves (protozoa) couldn't completely hide all evidence of the captive algae, and have been effectively frozen in time and caught in the act by genetic sequencing....

Algae Draws Energy From Other Plants
2012-11-21 11:22:20

Bielefeld University Astonishing research finding by biologists at Bielefeld University published in the online journal Nature Communications Flowers need water and light to grow. Even children learn that plants use sunlight to gather energy from earth and water. Members of Professor Dr. Olaf Kruse´s biological research team at Bielefeld University have made a groundbreaking discovery that one plant has another way of doing this. They have confirmed for the first time that a plant,...

Key To Controlling Fruit Ripening Could Be In The Functions Of Chloroplasts
2012-11-01 14:51:47

University of Leicester Biologists may have unearthed the potential to manipulate the functions of chloroplasts, the parts of plant cells responsible for photosynthesis. Researchers in the University of Leicester's Department of Biology discovered that chloroplasts are affected by the ubiquitin proteasome system (UPS) — a process which causes the breakdown of unwanted proteins in cells, previously thought to only act on central parts of the cell. As a result, the researchers...

Using a computational model they designed to incorporate detailed information about plants´ interconnected metabolic processes, scientists at the U.S. Department of Energy´s Brookhaven National Laboratory have identified key pathways that appear to “favor” the production of either oils or proteins. The research, now published online in Plant Physiology, may point the way to new strategies to tip the balance and increase plant oil production. The study focused on 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...

Green Solution In Fight Against Greenhouse Gases
2012-09-24 04:53:29

redOrbit Staff & Wire Reports - Your Universe Online Researchers are working on safer, more cost-effective carbon capture technology that could help overcome some of the obstacles currently facing projects designed to help reduce greenhouse gases and combat global climate changes, according to several recently published news reports. On Sunday, Reuters reporter Chris Wickham detailed a new material constructed from aluminum nitrate salt, inexpensive organic materials, and water...

Marine Microbes Engage In Unusual Symbiosis
2012-09-22 09:56:42

April Flowers for redOrbit.com - Your Universe Online A study published in this week's issue of Science shows how tiny, single-celled algae and a highly specialized bacteria have formed a partnership that helps keep the ocean fertilized.  This symbiotic pair takes nitrogen from the atmosphere and "fixes" it into a form that other organisms can use. The results of the study emerged from the investigation of a mysterious nitrogen-fixing microbe that has a very small genome. ...

Crops Possibly Protected From Stressors Due To New Discovery
2012-08-31 16:37:30

Salk findings of a key genetic mechanism in plant hormone signaling may help save crops from stress and help address human hunger Scientists at the Salk Institute for Biological Studies have discovered a key genetic switch by which plants control their response to ethylene gas, a natural plant hormone best known for its ability to ripen fruit, but which, under stress conditions, can cause wilted leaves, premature aging and spoilage from over-ripening. The findings, published August 30 in...

Bittercress (Barbarea vulgaris), also commonly known as Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and Wound Rocket, is a European biennial herb. This plant displays a rosette of shiny, dark green leaves at the base and additional pinnately divided leaves on the stem. In the spring, yellow flowers originate in tightly packed terminal groups just above the foliage. Bittercress grows wildly as a weed in many parts of North America. The flowers can be in bloom May...

The Par Rubber Tree (Hevea brasiliensis), is a tree belonging to the family Euphorbiaceae. It is the most economically important member of the genus Hevea. It is of major economic importance because its sap-like extract (latex) can be collected and is the primary source of natural rubber. The Pará rubber tree initially grew only in the Amazon Rainforest. Now most rubber tree plantations are in southeast Asia and tropical Africa. Attempts to cultivate the tree in other areas in South...
