Desert dust enables algae to grow
Biologists from the Royal Netherlands Institute for Sea Research have demonstrated that desert dust promotes the growth of algae. Scientists had already assumed that the iron in desert dust stimulated algal growth, but this has now been demonstrated for the first time. The researchers have published their findings in the December issue of the... view more... (2003-12-19)

Exploration of Saturn's rings aided by UK scientists
Scientists at the University of Sussex have produced synthetic 'cosmic dust' to help space researchers understand information gathered by a mission to Saturn. CASSINI, an unmanned probe launched by NASA in October 1997, is due to go into orbit around Saturn this summer. One of the aims of the CASSINI mission is to study the planet's famous rings.... view more... (2004-01-20)
U of Minnesota-led study reveals mysteries of deep-sea nutrients
Iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor, a new study led by a University of Minnesota scientist shows. view more (2009-02-09)
NASA'S Dirty Secret: Moon Dust
The Apollo Moon missions of 1969-1972 all share a dirty secret. "The major issue the Apollo astronauts pointed out was dust, dust, dust," says Professor Larry Taylor, Director of the Planetary Geosciences Institute at the University of Tennessee. Fine as flour and rough as sandpaper, Moon dust caused 'lunar hay fever,' problems with... view more... (2008-09-29)
Iron supplements may relieve unexplained tiredness in young women
Unexplained tiredness is common in young women. In this week's BMJ, researchers find that non-anaemic women with fatigue may benefit from taking an iron supplement. The study took place in Switzerland and involved 136 women aged 18 to 55 who consulted a doctor with fatigue, but who were not anaemic. They were divided into two groups; one group... view more...

Iron on its route to the sea-floor: A new path
Iron dust, the rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or--a surprising new study finds--float up from the sea floor in the material spewed from hydrothermal vents. view more (2009-02-09)
Homoeopathy is not an effective treatment for asthma
Homoeopathic remedies are no better than placebo for the treatment of asthmatic patients who are allergic to house dust mite, but there is a difference in response between homoeopathy and placebo, concludes a study in this week's BMJ. The research team identified 242 asthmatic people allergic to house dust mite. Participants received either... view more... (2002-02-27)
Dust threatens Kyoto protocol
On the eve of the Earth Summit in Johannesburg, scientists at UCL have detected a flaw in the Kyoto protocol`s global plans to reduce the impact of global warming, all because of something as simple as atmospheric dust. Dr Mark Maslin of UCL`s Environmental Change Research Centre explains: "Dust is vital to the health of the planet. This is not... view more... (2002-08-07)
ISO satellite investigates dust discs around stars
investigate the dust discs around normal stars. Those few stars which are surrounded by clouds of dust (our own Sun is surrounded by a dust cloud) would form a list of stars which might have orbiting planets - some of which may support life. These stars would be among the first to be investigated by future space missions searching for signs of... view more... (1996-10-31)
Ironing out malnutrition
Two of the three keys are in place to unlock the secret to controlling and enhancing plant iron uptake. Scientists are poised to identify the final step in the process that could supply the world with iron-rich crops. Collaboration between American and French scientists has led to the identification of three key genes involved in iron uptake in... view more... (2001-04-02)

Rapid growth of cancer cells and their frequent divisions have their price: Cancer cells need considerably more energy than healthy cells. view more (2009-03-11)
XMM-Newton takes astronomers to a black hole's edge
Using new data from ESA's XMM-Newton spaceborne observatory, astronomers have probed closer than ever to a supermassive black hole lying deep at the core of a distant active galaxy. view more (2009-05-28)
Plymouth Leads 'healthy Oceans' Research
Plymouth researchers will be presenting new research findings at an international conference they are hosting in the city next month. Professor Paul Worsfold, Co-director of Plymouth Environmental Research Centre (PERC), heads the Plymouth team working on a three-year research project which investigates the role of iron in ocean productivity and... view more...

Cornell-led team detects dust around a primitive star, shedding new light on universe's origins
A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust. view more (2009-01-16)
Dust clouds in cosmic cycle
It has been a mystery for astronomers how certain dying stars have their colossal quantities of material blown out into the universe and shrink into objects called "white dwarves". view more (2007-04-05)
Answering that age-old lament: Where does all this dust come from?

Iron Can Have Negative Side Effects On People With Kidney Disease
More than 20 million Americans- one in nine adults- have chronic kidney disease, and most don't even know it.[1] Physicians are constantly searching for the most effective therapies to help people with end-stage renal disease (ESRD), which occurs when kidney disease has progressed and about 90% of kidney function has been lost. While iron therapy... view more... (2004-07-30)
