Research team finds that microorganisms
filter nitrogen from small streams
To understand how nitrogen accumulates in large rivers and oceans miles
and miles away, scientists like Walter Dodds looked at small streams
flowing closer to home.

The puzzling 'eye of a hurricane' on
Venus
Venus Express has constantly been observing the south pole of Venus and
has found it to be surprisingly fickle. An enormous structure with a
central part that looks like the eye of a hurricane, morphs and changes
shape within a matter of days, leaving scientists puzzled.

Compound removes radioactive material
from power plant waste
Strontium 90 is a common radioactive by-product of fission in nuclear
power plants. When extracted from the reactor along with other isotopes,
a mixture is created made up of the radioactive material and inert ions
like sodium and calcium. Scientists at US Department of Energy's Argonne
National Laboratory and Northwestern University have developed a
compound that captures the radioactive ions so they can be siphoned off
and separated from inert material.
