Space X-ray telescope arrives for tests at RAL
An X-ray telescope weighing half a tonne, due for launch on a Russian spacecraft in 1998, arrived at CLRC's Rutherford Appleton Laboratory today for thermal tests. With conditions in space so different from those on Earth (space is an icy-cold vacuum), it is vital to test any instrument before launch to make sure that it can work in a vacuum at... view more...

New metal alloys boost high-temperature heat treatment of jet engine components
Measurement scientists at the National Physical Laboratory have reduced the uncertainty of thermocouple temperature sensors at high temperatures to within a degree. view more (2007-07-25)
Study Compares Sound from Exploding Volcanoes with Jet Engines
New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. view more (2009-04-09)
New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system. view more (2009-11-13)
Weather, stomach bugs and climate change: Refining the model
Monitoring extreme weather, such as periods of high temperature, is one way to predict the timing and intensity of infectious diseases like cryptosporidiosis, an intestinal disease that causes upset stomach and diarrhea. view more (2008-06-05)
Improved e-jet printing provides higher resolution and more versatility
By combining electrically induced fluid flow with nanoscale nozzles, researchers at the University of Illinois have established new benchmarks for precision control and resolution in jet-printing processes. view more (2007-09-10)
Researchers propose new molecule to explain circadian clock
The internal clock in living beings that regulates sleeping and waking patterns -- usually called the circadian clock -- has often befuddled scientists due to its mysterious time delays. Molecular interactions that regulate the circadian clock happen within milliseconds, yet the body clock resets about every 24 hours. view more (2007-08-28)
Piling on the homework -- Does it work for everyone?
While U.S students continue to lag behind many countries academically, national statistics show that teachers have responded by assigning more homework. view more (2008-08-19)
Argonne scientists reveal interaction between supersonic fuel spray and its shock wave
Shock waves are a well tested phenomenon on a large scale, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators from Wayne State University and Cornell University have made a breakthrough that reveals the interaction between shockwaves created by high-pressure supersonic fuel jets. view more (2009-03-13)
Salivary melatonin may decrease periodontal disease severity according to new study findings
Salivary melatonin may play an important role in maintaining periodontal health, according to a new study published in the Journal of Periodontology. view more (2006-09-13)
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)
Prenatal alcohol exposure can alter circadian rhythms in offspring
Children with fetal alcohol spectrum disorders (FASD) suffer from a variety of behavioral alterations. For example, they may exhibit alterations in sleeping and eating patterns, which may indicate that their circadian systems - which control biological rhythms - have been affected by alcohol exposure during development. view more (2006-04-24)
Is the sky the limit for wind power?
In the future, will wind power tapped by high-flying kites light up New York? A new study by scientists at the Carnegie Institution and California State University identifies New York as a prime location for exploiting high-altitude winds, which globally contain enough energy to meet world demand 100 times over. view more (2009-06-16)
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)
Faster atmospheric warming in subtropics pushes jet streams toward poles
The atmosphere is warming faster in subtropical areas, around 30 degrees north and south latitude, than it is elsewhere, University of Washington-led research shows. view more (2006-05-26)
Melatonin may save eyesight in inflammatory disease
Current research suggests that melatonin therapy may help treat uveitis, a common inflammatory eye disease. The related report by Sande et al., "Therapeutic Effect of Melatonin in Experimental Uveitis," appears in the December issue of The American Journal of Pathology. view more (2008-11-24)
Negative effects of caffeine are stronger on daytime sleep than on nocturnal sleep
A new study at the Université de Montréal has concluded that people drinking coffee to get through a night shift or a night of studying will strongly hurt their recovery sleep the next day. view more (2006-10-03)
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)
Foster care may boost brain activity of institutionalized children
Children raised in institutions are more likely to lag physically, socially, and cognitively, but little is known about what happens to children's brains when they live in institutions. view more (2009-07-15)
