Small streams mitigate human influence on coastal ecosystems
Healthy streams play a major role in minimizing the amount of human-generated pollutants, such as nitrogen, that are delivered downstream. view more (2008-03-13)
Field Project Seeks Clues to Climate Change in Remote Atmospheric Region
Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting the amount of solar heat that reaches Earth's surface. view more (2008-06-13)
New fruit fly protein illuminates circadian response to light
Researchers at the University of Pennsylvania School of Medicine have identified a new protein required for the circadian response to light in fruit flies. view more (2006-06-30)
Researchers design pulsed mircrojet system to deliver protein drugs without pain or bruising
A team of UCSB researchers, in collaboration with colleagues from UC Berkeley and StrataGent Life Sciences, of Los Gatos, California, has designed a novel pulsed microjet system engineered to deliver protein drugs into the skin without the pain or bruising that deeper penetration injection systems cause. view more (2007-03-07)
Photocell Provides Both Heat And Electricity
In 1969, scientists at the Ioffe Physico-Technical Institute, St. Petersburg made heterostructured photoelectric cells based on the elements of the third and the fifth group of the periodic table (for example, gallium arsenide). Now the photocells can find application not only in space, but also on Earth. To make them working the sunlight is not... view more... (2001-11-27)
Fusion to play part in UK energy strategy
Fusion is one of the research areas picked out for energy investment from the UK government by the House of Commons Science and Technology Committee in its Report on Energy Research published yesterday. The report "Towards a non-carbon fuel economy: research, development and demonstration" looks at the state of development of different... view more... (2003-04-04)
Faster than the speed of sound: New control system has what it takes to guide experimental aircraft
When a jet is flying faster than the speed of sound, one small mistake can tear it apart. And when the jet is so experimental that it must fly unmanned, only a computer control system can pilot it. Ohio State University engineers have designed control system software that can do just that -- by adapting to changing conditions during a flight. view more (2009-04-30)
Scientists show that streams are critical to preservation of oceanic coastal zones
The plight of the world's oceans is dire, according to recent studies, through insults from human-derived activities depopulating and damaging reefs, altering coastlines, and creating pollutants, such as nitrogen runoff from terrestrial watersheds. view more (2008-03-13)
New finding may aid adult stem cell collection
Cincinnati scientists have discovered how blood-regenerating stem cells move from bone marrow into the blood stream. view more (2005-07-28)
UGA study reveals ecosystem-level consequences of frog extinctions
Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They're victims of a fungus that's decimating amphibian populations worldwide. view more (2008-10-17)
Radiologists and engineers develop a modified catheter to reduce contrast material injuries
Though rare, IV contrast material administration can sometimes result in patient injury. However researchers have developed a modified catheter that may prevent such events from occurring. view more (2009-09-21)
Antarctic Ice Sheet's Hidden Lakes Speed Ice Flow Into Ocean, May Disrupt Climate
Just as explorers once searched the vast reaches of Africa's Nile River for clues to its behavior and ultimate source, modern-day scientists are searching Antarctica for its hidden lakes and waterways that can barely be detected at the surface of the ice sheet. view more (2007-03-07)
Custom filler material produces excellent paint without common damage to mixing equipment
In order to produce paint of the highest possible quality, the raw materials must be tightly controlled. This includes the mineral fillers that make up to 50% of the paint. Filler materials like calcium carbonate, talc, kaolin and silica largely govern paint properties like UV resistance, weatherability, abrasion resistance and sheen. view more (2006-05-22)
Hanover Trade Fair 2003: The six-pack mixer
Flexible liquid distribution system for numbering-up in micro process engineering In theory it sounds simple - numbering-up provides more throughput: As many microreactors or micromixers are switched to parallel operation until the desired production performance is achieved. In practical working, this concept quickly reaches its economic limits... view more... (2003-04-07)
Through the sound barrier without a boom?
Supersonic aircraft might not be plagued by the problem of sonic boom if a radical design proposal by a Cambridge academic could be made to work. Professor John Ffowcs Williams, Master of Emmanuel College Cambridge, directed the Concorde Noise Panel in the 1960s and 70s. He now believes it is possible to build an aeroplane that could pass through... view more... (2002-05-27)
Vamco's Gusty Remnants Cause High Wind Warnings in Alaska's Aleutian Islands
The remnants from Typhoon Vamco are sweeping over Alaska's Aleutian Island chain today and tomorrow, and high wind warnings have been posted by the National Weather Service.

New X-ray technique may lead to better, cleaner fuel injectors for automobiles
Standard microscopy and visible light imaging techniques cannot peer into the dark and murky centers of dense-liquid jets, which has hindered scientists in their quest for a full understanding of liquid breakup in devices such as automobile fuel injectors. view more (2008-02-25)
As world warms, water levels dropping in major rivers
Rivers in some of the world's most populous regions are losing water, according to a comprehensive study of global stream flows. view more (2009-04-22)
Friction Inside The Earth Is A Source Of Heat
There is high temperature inside our planet and the reason is not known yet. A common belief that the Earth`s interior is heated by radioactive elements is now doubted of. Professor Felix Letnikov from Irkutsk Institute of the Earth`s Crust have proposed an idea that the heat is formed in the outer core because of friction between its layers.... view more...

ORNL study finds rivers play part in removing nitrogen
Tiny organisms play a powerful role in removing nitrate, a form of nitrogen pollution caused by human activity, in streams, according to a study by a team led by Oak Ridge National Laboratory and published in Nature. view more (2008-03-13)
