Beer Tapping Physics Explained
2013-11-25 04:26:11

Alan McStravick for redOrbit.com - Your Universe Online My first experience with the behavior of forcefully tapping the bottom of a beer bottle to the top of another, creating a foamy overflow, was in the rowdy crew bar of the Queen Elizabeth 2 on which I served in the entertainment department in my much younger days. And more than one bottled brew was significantly emptied onto the bare floors of one frat house party or another during numerous college weekends. Now, thanks to a group of...

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...

Study Of Photosynthesis Clears Path To Developing New Super-crops
2013-10-17 16:32:44

How some plant species evolved super-efficient photosynthesis had been a mystery. Now, scientists have identified what steps led to that change. Around three per cent of all plants use an advanced form of photosynthesis, which allows them to capture more carbon dioxide, use less water, and grow more rapidly. Overall this makes them over 50% more efficient than plants that use the less efficient form. A new study has traced back the evolutionary paths of all the plants that use advanced...

Understanding the impact of environmental change on plant traits is an important issue in evolutionary biology. As the only direct evidence of past life, fossils provide important information on the interactions between plants and environmental change. After ten years' survey, Professor Zhou Zhekun's group from Kunming Institute of Botany has discovered more than ten well preserved Neogene plant fossil sites in southwestern China which are important to understand past climate and response of...

Special microscope used to reveal hidden aspects of plant anatomy Why don't trees "bleed" to death when they are injured? Researchers from Virginia Tech, the Georg-August University of Gottingen, Germany, and the Jackson Laboratory of Bar Harbor, Maine, have discovered how "check valves" in wood cells control sap flow and protect trees when they are injured. The study, featured on the cover of the September issue of the American Journal of Botany, used a special microscope to reveal...

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...

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...
