Straw residue helps keep nitrogen on the farm

Straw residue helps keep nitrogen on the farm

MADISON, WI, May 24, 2010-Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return.

Organic solids in soil may speed up bacterial 'respiration'

MADISON – The "mineral-breathing" bacteria found in many oxygen-free environments may be "carbon-breathing" as well.

Oxygen-free, or anaerobic, environments contain microbes sometimes described as "mineral-breathing" because they use iron oxides and other minerals in the same way we use oxygen. According to a study published online May 23 in Nature Geoscience, this bacterial respiration may be accelerated by solid organic compounds in the soil.

Einstein wrong about Brownian motion, say University of Texas physicists

AUSTIN, Texas—A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done so.

NASA's Aqua satellite sees second tropical storm form near the Horn of Africa

The Northern Indian Ocean cyclone season is off to a roaring start, as the second tropical storm formed within a day of the first one. NASA's Aqua satellite flew over Tropical Storm 02A today, May 19 and captured infrared, microwave and visible images of the storm.

Disease control, not climate change, key to future of malaria

A study published today in the journal Nature casts doubt on the widely held notion that warming global temperatures will lead to a future intensification of malaria and an expansion of its global range.

The research, conducted by the Malaria Atlas Project (MAP), a multinational team of researchers funded mainly by the Wellcome Trust, suggests that current interventions could have a far more dramatic – and positive – effect on reducing the spread of malaria than any negative effects caused by climate change.

U of Minn. study finds rising levels of dioxins from common soap ingredient in Mississippi River

Specific dioxins derived from the antibacterial agent triclosan, used in many hand soaps, deodorants, dishwashing liquids and other consumer products, account for an increasing proportion of total dioxins in Mississippi River sediments, according to University of Minnesota research.

NASA's Aqua satellite sees Tropical Storm 1B form in Bay of Bengal

The first tropical storm of the Northern Indian Ocean cyclone season has formed and NASA's Aqua satellite captured its birth. Tropical Storm 1B formed in the early morning hours as the convection around the low level circulation center increased since May 17.

Earth's 'reset' button paved the way for modern vertebrates

A mass extinction of fish 360 million years ago hit the reset button on Earth's life, setting the stage for modern vertebrate biodiversity. The mass extinction scrambled the species pool near the time at which the first vertebrates crawled from water towards land.

Those few species that survived the bottleneck were the evolutionary starting point for all vertebrates--including humans--that exist today, according to results of a study published this week in the journal Proceedings of the National Academy of Sciences (PNAS).
