Mon, 09 Jun 2008 Lower Crop Yields Due To Ozone A Factor In World Food Crisis. Heat waves, droughts and fuel prices are just a few reasons for the current global food crisis that is making headlines around the world. New research indicates that rising background levels of ozone in the atmosphere are a likely contributor to the problem, lowering the yield of important food crops, such as wheat and soybeans.more

Mon, 09 Jun 2008 Magnet-controlled Camera In The Body. Images from inside the body? It can be done with tiny cameras which the patient has to swallow. In the past there was no way of controlling the device as it passed through the body. Now it can be steered and stopped where desired, and even deliver images of the esophagus.more

Mon, 02 Jun 2008 How Enzyme Works: A Molecular Switch Turns On The Flame In "Nature"s Blowtorch". Uncontrolled reaction of organic compounds with oxygen is easy: we call it fire. But nature often needs to do oxidations very specifically, adding oxygen to a particular carbon atom in a complicated molecule without disturbing anything else. Usually, this job falls to an enzyme called cytochrome P450.more

Tue, 27 May 2008 Electron Traps That Compute. Physicists have used a semiconductor material to create superimposed quantum dots that "trap" single electrons. Not only can these dots be studied with lasers, their energy can be influenced as well. Another point: the state of one of the dots governs that of the other above it. This has taken the researchers another step closer to quantum computers.more

Thu, 22 May 2008 Scientists Develop Way To Predict Properties Of Light Nuclei. Scientists have spent 70 years trying to predict the properties of nuclei, but have had to settle for approximate models because computational techniques were not equal to the task. Scientists at U.S. Department of Energy"s Argonne National Laboratory have learned to compute what happens when nuclei collide.more
