New NRPB Poster published for National Science Week - Sunsense: Protecting Yourself from Ultraviolet Radiation (UVR)
To co-incide with National Science Week (starting 8 March 2002) NRPB is publishing a new poster - Sunsense: Protecting Yourself from Ultraviolet Radiation (UVR). The poster provides important facts on protecting yourself from UVR. It summarises what is known about the health effects of UVR. The aim is to personalise the science behind a serious... view more... (2002-03-12)
Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight. view more (2008-08-25)
Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in temperature caused by the greenhouse effect is doing... view more... (2001-11-26)
How Increased UV Exposure Impacts Plants
As the first plant life to emerge from the water and develop on dry earth, bryophytes offer a unique opportunity for researchers to understand the development of protections against ultraviolet radiation. view more (2009-03-10)
UNC scientists discover cellular 'SOS' signal in response to UV skin damage
New research from the University of North Carolina at Chapel Hill School of Medicine has identified two proteins that may help protect against skin cancer. view more (2007-03-19)
Sun exposure seems to reduce risk of multiple sclerosis
Higher sun exposure during childhood and early adolescence is associated with a reduced risk of multiple sclerosis, finds a study in this week's BMJ. Multiple sclerosis is more common at higher latitudes, which generally have lower levels of ultraviolet radiation. The study was carried out in Tasmania, which is located at high latitude and has a... view more... (2003-08-06)
DNA repair mechanisms are concentrated in the active parts of the genome
Less than 10% of the human genome contains coded information in the form of genes. The 30,000-40,000 genes in the genome are found grouped in discrete regions of the chromosomes. Chemical agents and radiation habitually cause a large variety of injuries to the DNA which interferes in many cell processes, like transcription and replication, and... view more... (2002-10-01)
The light and dark of Venus
Venus Express has revealed a planet of extraordinarily changeable and extremely large-scale weather. Bright hazes appear in a matter of days, reaching from the south pole to the low southern latitudes and disappearing just as quickly. view more (2008-02-22)
Winds of 320 000 kilometres per hour on the Sun
The SUMER instrument on the ESA-NASA SOHO spacecraft has measured amazing wind speeds during its observations of the Sun. It sets a new record in its examination of two loops of gas arching in the solar atmosphere, where NASA`s TRACE satellite spotted bright blobs of gas. Shifts in the wavelength of ultraviolet light from highly ionized neon... view more... (2002-05-17)
New Study Looks At Sensitivity To Sun
A project designed to try and explain the way genes influence sensitivity to sun is underway at the University of Edinburgh. The study will look not only at the role of ultraviolet radiation in causing skin cancer, but at its benefits in treating of patients with psoriasis, eczema and a range of other skin conditions. Professor of Dermatology... view more... (2002-04-24)
World's most powerful ultraviolet laser inaugurated
Titania will be the most powerful ultraviolet laser world-wide and has the capacity to generate up to 10 terawatt power in single pulses of duration down to 300 femtoseconds. It will be inaugurated at a special ceremony today (Tuesday 2 April) by Dr Paul Williams, Chief Executive of CCLRC, who will fire the new facility's first shot. Titania is... view more...

Ultraviolet radiation induced flux of nitrogen oxides from pine needles
In the latest edition of Nature (March 13th, 2003) a group of scientist led by professor Pertti Hari from the University of Helsinki presents a novel observation: ultraviolet radiation induced a flux of nitrogen oxides (NOx) from pine needles to the atmosphere. This result is interesting because nitrogen oxides participate in several essential... view more... (2003-03-14)

Tanning Devices - Fast Track to Skin Cancer?
An all over tan is fashionable and large numbers of people, especially young women, achieve this by using sunbeds. Professor Antony Young, of King's College London, has reviewed the evidence that links sunbed use to malignant melanoma; a skin cancer that is fatal if not detected and treated early. Malignant melanoma is a cancer of the skin's cells... view more... (2004-01-15)
Ultraviolet astronomy in danger
World astronomers are becoming very concerned about their ability to carry out observations in ultraviolet light following recent announcements about the future of the Hubble Space Telescope. Hubble is most famous for the clear images it gives of distant objects from its vantage point above the Earth's atmosphere. It is less well known that its... view more... (2004-03-23)
Sunscreens can damage skin, researchers find
Are sunscreens always beneficial, or can they be detrimental to users? A research team led by UC Riverside chemists reports that unless people out in the sun apply sunscreen often, the sunscreen itself can become harmful to the skin. view more (2006-08-29)
Some color shades offer better protection against sun's ultraviolet rays
Economy-minded consumers who want protection from the sun's harmful ultraviolet (UV) rays - but rather not pay premium prices for sun-protective clothing - should think blue and red, rather than yellow. view more (2009-10-15)
Doses from Discharges now in electronic format
Doses from Discharges is the latest electronic module, based on the NRPB At-a-Glance printed series of broadsheets, to appear on the NRPB website (http://www.nrpb.org/understand/index.htm). Modules for Radon, Transport of Radioactive Materials and Nuclear Emergencies are already to be found on the website, in the Understanding Radiation section,... view more... (2003-03-07)
Broccoli sprout-derived extract protects against ultraviolet radiation
A team of Johns Hopkins scientists reports in this week's issue of the Proceedings of the National Academy of Sciences that humans can be protected against the damaging effects of ultraviolet (UV) radiation - the most abundant cancer-causing agent in our environment - by topical application of an extract of broccoli sprouts. view more (2007-10-23)
University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. view more (2009-09-16)
