Clean forests prompt pollution rethink

South American streams call current nitrogen-cycle theory into question.

Pollution may have altered northern hemisphere forests dramatically. The surprise finding that clean forests use nitrogen differently to polluted ones emphasizes the effect that humans have on the planet’s nitrogen cycle 1 . It may even prompt a rethink of the way that this cycle works.

Humans have added vast amounts of nitrogen to the earth’s ecosystems. The element fertilizes plants. T

Event horizon dawns on desktop

Miniature physics phenomena could show hidden shades of space.

An event horizon is dawning in laboratories. Using frozen light, physicists hope to mimic this peculiar cosmic phenomenon and glimpse something like the belches of a black hole.

At the event horizon – the rim of a voracious black hole – dimensions as we know them disappear. To an observer on a spaceship, light and time appear to stand still. A floating spaceman would seem to slow and stop.

Seismic rumbling foretold Congo eruption

Scientists received several day’s warning of abnormal seismic activity.

Two seismological stations on Mount Nyiragongo in eastern Congo gave several days’ advance warning of the volcano’s possible eruption, scientists working in the area say.

But the lack of a functioning government in the war-torn region may have prevented the evacuation of the nearby city of Goma, where 45 were confirmed dead and an existing humanitarian crisis was worsened by the eruption.

Crystals For Extreme Electronics

Like silicon, silicon carbide is semiconductor and in some aspects, its characteristics are even better. Electrical strength of silicon carbide is ten times higher than that of silicon, heat conductivity is three times higher. Crystals of silicon carbide are almost perfect for power electronics. They can work at high current density (more than 10 kA per square centimeter) and voltage up to 4.5 kV, unachievable for silicon. Moreover, charge-drift velocity is twice higher in silicon carbide providing b

Atmosphere and Oceans Finely Balanced

The atmosphere and oceans exist in a delicate state of balance according to research co-ordinated by the University of East Anglia (UEA) and published this month by the Natural Environment Research Council (NERC).

The recently completed five year research programme of Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) concludes that atmospheric pollution travels much further than previously thought and that this has important consequences for global chemistry and climate.

Turning unwanted straw into valuable products for industry

Common or garden straw could be a rich source of raw materials for a range of industries, from the health foods and cosmetics sectors to packaging and fabrics.
Researchers at the University of Wales, Bangor are developing environmentally friendly ways of processing wheat and other cereal straws to extract valuable products for industry.

The work is being carried out through the Government’s LINK scheme, with funding from the Swindon based Engineering and Physical Sciences Research Coun
