Production of spherical beads with the JetCutter
A major problem in particle production technology is the large scale production of uniform beads from viscous fluids. Producing such beads is of interest in various industrial sectors, e.g. chemical, pharmaceutical and food industry, agriculture, biotechnology. The JetCutter is a new and simple technology for bead production that meets the... view more... (2003-11-03)
Evidence for ultra-energetic particles in jet from black hole
An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of galaxies and radiate across the spectrum from radio to X-ray wavelengths. view more (2006-06-21)
The Double Firing Burst
Astronomers from around the world combined data from ground- and space-based telescopes to paint a detailed portrait of the brightest explosion ever seen. The observations reveal that the jets of the gamma-ray burst called GRB 080319B were aimed almost directly at the Earth. view more (2008-09-11)
IGBP calls for better observation of Earth's "Achilles' heels"
Monitoring the most sensitive "hotspots" of the Earth is an important way of assessing the health of our planet and predicting our future, said IGBP (International Geosphere-Biosphere Programme) scientists speaking at the Earth Observation Summit in Washington last week. The summit was attended by officials from more than 30 countries... view more... (2003-08-06)
Pressure relief for jet engines - Photon02
The aerodynamics inside jet engines are not completely understood due to the unpredictable nature of the air flowing through the turbine. However, a research team led by Dr Jim Barton from Heriot-Watt University, has developed tiny fibre optic pressure sensors that can for the first time be used inside jet engine test rigs. These sensors should... view more... (2002-08-28)
Living, Meandering River Constructed
In a feat of reverse-engineering, Christian Braudrick of University of California at Berkeley and three coauthors have successfully built and maintained a scale model of a living meandering gravel-bed river in the lab. view more (2009-09-30)
Mapping Orion's winds
For the past few months, Bob O'Dell has been mapping the winds blowing in the Orion Nebula, the closest stellar nursery similar to the one in which the sun was born. view more (2006-01-11)
ANALYTICA 2004: Infrared Sensor is Kind to Costs and Environment
The IMM Institut für Mikrotechnik Mainz GmbH has developed an infrared sensor for the quality control of lubricants in machines. With this sensor, oil and its ageing can be monitored directly at the operating machine. Future fields of application are for example real-time monitoring of large motors, particularly in shipping or compressors.... view more... (2004-05-10)
New protocol tracks how land use influences the way streams work
Virginia Tech biology researchers have applied tools from geology, geography, and hydrologic modeling to determine the effect of different land uses on stream quality across 10 watersheds of the French Broad River in the North Carolina mountains. view more (2005-10-13)
Past regional cold and warm periods linked to natural climate drivers
Intervals of regional warmth and cold in the past are linked to the El Niño phenomenon and the so-called "North Atlantic Oscillation" in the Northern hemisphere's jet stream, according to a team of climate scientists. These linkages may be important in assessing the regional effects of future climate change. view more (2009-11-30)
A bizarre hovering spy plane takes to the skies
WHAT looks like a flying saucer, takes off like a helicopter and flies like a plane? The next remote-controlled surveillance aircraft on the hunt for terrorist fugitives like Osama bin Laden, apparently. Pilotless aircraft came into their own in the Afghan conflict, greatly reducing casualties in US Air Force and ground troops on both... view more... (2002-01-30)
New Hypothesis Of The Tunguska Explosion
The event which occurred almost a hundred years ago in Podkamennaya Tunguska has drawn scientists` attention again. What actually exploded at that time in the remote taiga, the power of explosion being equal to the 50-megaton H-bomb? The hypothesis that it was a meteorite or any other extraterrestrial object has not quite satisfied inquisitive... view more... (2002-08-23)
Skid Marks in the Galaxy - Astronomers localise galactic particle accelerator
Radio galaxies are amongst the most luminous celestial objects - however, they mainly emit radio waves, not light. These occur when electrically charged particles travelling at almost the speed of light are slowed down, thereby losing energy. Until recently it was not known exactly where the particles reach such high speeds. A group of scientists... view more... (2002-10-16)
'Naked-eye' gamma-ray burst was aimed squarely at Earth
Data from satellites and observatories around the globe show a jet from a powerful stellar explosion witnessed March 19 was aimed almost directly at Earth. view more (2008-09-12)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Erratic Black Hole Regulates Itself
New results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce. These results suggest that these black holes have a mechanism for regulating the rate at which they grow. view more (2009-03-26)
Fighting sound with sound, new modeling technique could quiet aircraft
Newly published research by a Princeton engineer suggests that understanding how air travels across the sunroof of a car may one day make jet engines less noisy. view more (2006-02-27)
Data show Antarctic ice stream radiating seismically
A seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial. view more (2008-06-05)
Studying the fate of drugs in wastewater
Researchers at the National Institute of Standards and Technology (NIST) have published an interesting study that sheds light on the fate of a familiar pharmaceutical as it enters the waste stream. view more (2005-12-27)
Salamanders, headwater streams critical in food chain
University of Missouri scientist Ray Semlitsch studies creatures most people don't ever see. These creatures are active only at night and thrive in the shallow, cool, wet surroundings of headwater streams, an oft-overlooked biological environment. view more (2008-02-22)
