Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
Hubble's new view of the Carina Nebula shows the process of star birth at a new level of detail. view more (2007-04-25)
Venus comes to life at wavelengths invisible to human eyes
A pale yellow-green dot to the human eye, Earth's twin planet comes to life in the ultraviolet and the infrared. New images taken by instruments on board ESA's Venus Express provide insight into the turbulent atmosphere of our neighbouring planet. view more (2008-12-04)
High Power Laser for Ultraviolet Light
An international team of scientists at the research center DESY recently succeeded in obtaining the maximum light amplification from a "free electron laser" (FEL) for ultraviolet radiation. The electron laser produced an amplification of 10 million - this corresponds to the theoretically expected peak performance for such a device and presents a... view more... (2001-09-19)
Nanoparticles + light = dead tumor cells
Medical physicists at the University of Virginia have created a novel way to kill tumor cells using nanoparticles and light. view more (2008-07-30)
How Life Originated In Space
Life originated on the Earth more than 3.5 billion years ago. However, the scientists are still disputing over the possible sources of the life origin. The matter is that life on our planet evolved from the molecular level to the level of bacteria organisms within 0.5 - 1 billion years, this period being very short for such an important... view more...

Ultraviolet B light exposure associated with increased risk of skin cancer
A decreased ability to repair chromosomal damage caused by exposure to ultraviolet B (UV-B) radiation in test tubes may be associated with an increased risk of the common skin cancers basal cell carcinoma and squamous cell carcinoma, but not of melanoma. view more (2005-12-21)
Exposure to sunlight could reduce asthma
Australian researchers have found that exposure to measured doses of ultraviolet light, such as sunlight, could reduce asthma. view more (2006-10-26)
Proton therapy lowers chance of later cancers
Patients who are treated with proton therapy (a specialized type of external beam radiation therapy using protons rather than X-rays to treat cancer) decreases the risk of patients developing a secondary cancer by two-fold, compared to being treated with standard photon radiation treatment. view more (2008-09-22)
NASA's Swift satellite images a galaxy ablaze with starbirth
Combining 39 individual frames taken over 11 hours of exposure time, NASA astronomers have created this ultraviolet mosaic of the nearby "Triangulum Galaxy." view more (2008-02-26)
The National Radiological Protection Board advises holiday makers against overexposure to high sunlight
The incidence of skin cancer in the UK has significantly increased in recent years. There are now over 40,000 new cases and nearly 2,000 deaths from skin cancer in the UK each year. Much of this increase has been attributed to overexposure to sunlight not only when abroad but also sunbathing at home. In one recent study in Scotland, a third of... view more... (2003-05-27)
Low dose radiation in infancy may affect intellect
Exposure to low doses of ionising radiation in infancy affects intellectual capacity in later life, conclude researchers from Sweden in this week's BMJ. CT scanning, which delivers high doses of ionising radiation, is increasingly being used in young children after minor head trauma. The study involved 3,094 men who had received radiation therapy... view more... (2004-01-03)
Lettuce gets a healthy suntan
Salad dressing aside, a pile of spinach has more nutritional value than a wedge of iceberg lettuce. That's because darker colors in leafy vegetables are often signs of antioxidants that are thought to have a variety of health benefits. view more (2009-05-19)
Unusual views of the Sun
For centuries, we have worshipped it and wondered at it, but it`s only now that we are getting a really good look at it. Although you can`t gaze at the Sun with the naked eye, thanks to modern science we can view images of our nearest star that confirm the fiery glory our ancestors could only imagine. Today, our views of the Universe are many... view more... (2002-05-21)
New technique reduces radiation exposure by 60 percent in abdominal CT of children
By lowering the tube current to account for both the weight and body symmetry of a child, an abdominal CT radiation dose can be reduced by 60% without compromising the image quality. view more (2006-05-02)
New on-off 'switch' triggers and reverses paralysis in animals with a beam of light
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. view more (2009-11-19)
New radiation technique can greatly reduce painful skin burns in women with breast cancer
Breast cancer patients who undergo a new radiation technique called intensity modulated radiation therapy (IMRT) after surgery are three times less likely to have severe skin reactions from the treatment compared to standard radiation therapy. view more (2006-11-07)
Measuring invisible reflections
The race is on for chip manufacturers. Many of them plan to open chip fabrication facilities employing extreme ultraviolet (EUV) radiation between up until 2010. This trend is being driven by advances in photolithography in which increasingly shorter wavelengths enable the production of even finer microelectronic structures. The result is higher... view more... (2003-07-25)
REDUCED LONGEVITY OF ATOMIC-BOMB SURVIVORS (p 303)
A study in this week's issue of THE LANCET does not support claims that atomic-bomb survivors exposed to certain doses of radiation live longer than comparable unexposed individuals. There have been conflicting claims regarding the biological and health consequences of exposure to low doses of radiation, with reports that some atomic-bomb... view more... (2000-07-19)
Silicon nanoparticles enhance performance of solar cells
Placing a film of silicon nanoparticles onto a silicon solar cell can boost power, reduce heat and prolong the cell's life, researchers now report. view more (2007-08-21)
Radiologists find a technique to significantly reduce patient radiation dose during CT angiography
Radiologists have discovered that prospective electrocardiogram (ECG) gating allows them to significantly reduce the patient radiation dose delivered during computed tomography (CT) angiography, a common noninvasive technique used to evaluate vascular disease. view more (2009-09-21)
