redOrbit Staff & Wire Reports - Your Universe Online Tropical forests that are timber harvested or cleared for agriculture can help reduce their own recovery time by capturing natural nitrogen fertilizer and carbon dioxide more quickly when making a comeback, according to research appearing in the journal Nature. In addition, researchers working at the Smithsonian Tropical Research Institute (STRI) in Panama found that an unusual symbiotic relationship between a specific group of...

The vision for a new branch of medicine, inspired by the ancient field that began with peg legs and hand hooks, commanded the spotlight in a major address by its pioneer here today at the 246th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. Martin D. Burke, M.D., Ph.D., focused on the field he has named "molecular prosthetics," after the small molecules that make up the ingredients in most drugs and the branch of medicine...

Prehistoric Europeans Used Spices

Brett Smith for redOrbit.com - Your Universe Online While today’s cutting-edge chefs use liquid nitrogen and futuristic food additives to achieve a desired effect, cooks have been manipulating meals as far back as the hunter-gatherer days. According to a new discovery being reported this week in the journal PLOS ONE, prehistoric chefs in modern day Denmark and Germany used mustard garlic as a food spice at least 6,000 years ago. Study researchers say tests on ancient pottery shards...

Lab-made Complexes Absorb More Sunlight
2013-08-21 15:47:02

Washington University in St. Louis A ring of protein and pigments, half synthetic and half natural, can be used to quickly prototype light-harvesting antennas that absorb more sunlight than fully natural ones In diagrams it looks like a confection of self-curling ribbon with bits of bling hung off the ribbon here and there. In fact it is a carefully designed ring of proteins with attached pigments that self-assembles into a structure that soaks up sunlight. The scientists who made it...

HDI debuts new mission statement to reflect role as multi-industry international company. Rome, GA (PRWEB) August 05, 2013 Hydro Dynamics, Inc. (HDI) announced its new mission statement today. The statement reads as follows, “To develop and implement cavitation technology across multiple industries, processes and nations allowing our customers to operate more efficiently and profitably. We will be globally recognized as the leader in cavitation technology with our ability to match...

Nitrogen Fixation System Could Eliminate The Need For Chemical Fertilizers
2013-07-26 05:01:36

Brett Smith for redOrbit.com - Your Universe Online Plant scientists from the University of Nottingham in the United Kingdom have announced a revolutionary new system that allows plants to take nitrogen from the atmosphere and potentially eliminate the need for chemical fertilizers that can pollute the ecosystem where they are used. Plants must fix nitrogen and convert it to ammonia in order to survive and grow - however, only a few plants, such as peas and lentils, have the ability to...

Trees Use Water More Efficiently Due To CO2 Rise
2013-07-11 08:01:38

redOrbit Staff & Wire Reports - Your Universe Online Trees are becoming more efficient at using water in response to higher atmospheric carbon dioxide levels, according to new research published Wednesday in the journal Nature. In the study, researchers including Dave Hollinger from the US Forest Service's Northern Research Station (NRS) and Trevor Keenan of Harvard University analyzed direct, long-term measurements of whole-ecosystem carbon and water exchange. According to...

Plants Resort To Math In Order To Survive Without Sunlight
2013-06-24 10:12:34

Brett Smith for redOrbit.com - Your Universe Online At night, plants must utilize nutrient reserves efficiently until dawn and new research from the John Innes Centre in England has found that some plants use basic math to survive without sunlight for photosynthesis. The British scientists said they were surprised to discover that Arabidopsis uses two different kinds of internal molecules to determine a rate for breaking down starch reserves. "This is the first concrete example in...

Quantum Secret In Photosynthesis Uncovered
2013-06-21 11:20:36

ICFO-The Institute of Photonic Sciences The efficient conversion of sunlight into useful energy is one of the challenges which stand in the way of meeting the world's increasing energy demand in a clean, sustainable way without relying on fossil fuels. Photosynthetic organisms, such as plants and some bacteria, have mastered this process: In less than a couple of trillionths of a second, 95 percent of the sunlight they absorb is whisked away to drive the metabolic reactions that provide...

Alpine Rock Cress Uses Ribonucleic Acid To Tell When It’s The Right Time To Flower
2013-06-10 15:52:15

Max Planck Institute Perennial plants flower only when they have reached a certain age and been subjected to the cold. These two circumstances prevent the plant from starting to flower during winter. George Coupland and his fellow scientists from the Max Planck Institute for Plant Breeding Research in Cologne have now discovered that the Alpine rock cress determines its age based on the quantity of a short ribonucleic acid. Perennial plants carefully balance periods of growth and...

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...
