Ed : Sadly no picture is available; however, you can find one in an article from last year, describing the group's research.

In a step toward making living cells function as if they were tiny computers, engineers at Princeton have programmed bacteria to communicate with each other and produce color-coded patterns.

The feat, accomplished in a biology lab within the Department of Electrical Engineering, represents an important proof-of-principle in an emerging field known as "synthetic biology," which aims to harness living cells as workhorses that detect hazards, build structures or repair tissues and organs within the body.

Zeroing in on the core cellular mechanisms of sleep, researchers at University of Wisconsin Medical School have identified for the first time a single gene mutation that has a powerful effect on the amount of time fruit flies sleep.

In its normal state, the Drosophila (fruit fly) gene, called Shaker, produces an ion channel that controls the flow of potassium into cells, a process that critically affects, among other things, electrical activity in neurons. A handful of recent studies suggest that potassium channels are also involved in the generation of sleep in humans.

Trees in the world¹s most productive forests -- forests that add the most new growth each year -- also tend to die young, according to a U.S. Geological Survey (USGS) study published in a recent issue of the journal Ecology Letters. This discovery could help scientists predict how forests will respond to ongoing and future environmental changes.

Mount Sinai School of Medicine researchers have discovered how the membrane protein that allows us to sense cold works and how this protein becomes desensitized so that one no longer feels the cold. The study, published this week as an advance online publication by Nature Neuroscience, focused on a specific region of the cold receptor which is found in many other receptors, including ones involved in taste, vision and fertilization. Therefore, the findings may have important implications across a wide range of areas.

A new online portal consolidates decades of rich marine data, much of it available for the first time, enabling resource managers and scientific researchers to combine and analyze information in unprecedented ways, creating new insights into the Gulf of Maine's ecology.

The "dead zone" area of the Gulf of Mexico – a region that annually suffers from low oxygen which can result in huge marine life losses – has appeared much earlier this year, meaning it could be potentially larger in 2005 and affect marine life more adversely than normal, researchers are reporting.

High-intensity focused ultrasound emitted in short pulses is a promising, non-invasive procedure for enhancing gene delivery to cancerous cells without destroying healthy tissue, according to a study in the May issue of the journal Radiology.

A significant debate is currently underway in the scientific community over the evolution of the Great White shark, and Chuck Ciampaglio, Ph.D., an assistant professor of geology at the Wright State University Lake Campus, is right in the middle of it.

The issue is if the Great White, one of the most feared predators of the sea, evolved from the huge prehistoric megladon shark or if its ancestry rests with the mako shark.

New research shows that a protein produced by a cancer-causing virus influences a key signaling pathway in the immune cells that the virus infects. This stimulates the cells to divide, helping the virus spread through the body.

The study, led by researchers at Ohio State University, examined the human T lymphotropic virus type 1 (HTLV-1) and a protein that it produces called p12.

Starvation, malnutrition and re-feeding can have deadly consequences for humans and most animals but not Australia's green-striped burrowing frog.

PhD student Rebecca Cramp from The University of Queensland has found that unlike most animals, which can't digest food after long periods of starvation, the green-striped burrowing frog is able to absorb nutrients 40 percent more effectively after 3 months without food, than frogs that had eaten regularly.
