- Genome-wide search unearths surprising clues for diabetes and triglycerides
04-26-2007 · EurekAlert!
Scientists from the Broad Institute of Harvard and MIT, Lund University and Novartis today announced the discovery of three unsuspected regions of human DNA that contain clear genetic risk factors for type 2 diabetes, and another that is associated with elevated blood triglycerides. The study is among the first to apply a suite of genomic resources to clinical research, including the Human Genome Project, the SNP and HapMap Projects, and genome-scale laboratory and analytical tools.

- When smell cells fail they call in stem cell reserves
04-29-2007 · EurekAlert!
Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. These reservists normally lie around and do nothing, but when neighboring cells die, the scientists say, the stem cells jump into action. A report on the discovery will appear online next week in Nature Neuroscience.

- Arizona State University scientist finds Martian ice is patchy and variable
05-02-2007 · EurekAlert!
For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.

- Origins of nervous system found in genes of sea sponge, report scientists at UC Santa Barbara
06-05-2007 · EurekAlert!
Scientists at the University of California, Santa Barbara, have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge, a member of a group considered to be among the most ancient of all animals.

- Higher efficiency organic solar cell created by UCSB Nobel Laureate and research team
07-12-2007 · EurekAlert!
Using plastics to harvest the energy of the sun just got a significant boost in efficiency thanks to a discovery made at UC Santa Barbara. Nobel laureate and Alan Heeger, professor at UC Santa Barbara, worked with Kwanghee Lee of Korea and a team of scientists to create a new "tandem" organic solar cell with increased efficiency. The discovery, explained in the July 13 Science, marks a step forward in materials science.

- CSHL scientists identify cells that promote formation of lethal lung metastases
01-10-2008 · EurekAlert!
Cancer patients usually ask what can be done after a primary tumor has already spread, or metastasized, to other organs. In many cases, they learn, little can be done. Hence the importance of a discovery by scientists at Cold Spring Harbor Laboratory of a type of cell that regulates the transformation of small, dormant lung metastases into large, aggressive metastases -- the kind that kill cancer patients.

- Scientists map key landmarks in human genome
01-16-2007 · EurekAlert!
Dana-Farber Cancer Institute researchers have developed a powerful method for charting the positions of key gene-regulating molecules called nucleosomes throughout the human genome. The mapping tool could help uncover important clues for understanding and diagnosing cancer and other diseases, the scientists say. Moreover, it may shed light on the role of nucleosomes in the process of "reprogramming" an adult cell to its original embryonic state, which is a critical operation in cloning.

- Algae provide new clues to cancer
10-12-2006 · EurekAlert!
A microscopic green alga helped scientists at the Salk Institute for Biological Studies identify a novel function for the retinoblastoma protein (RB), which is known for its role as a tumor suppressor in mammalian cells. By coupling cell size with cell division, RB ensures that cells stay within an optimal size range.

- Scientists: New phylum sheds light on ancestor of animals, humans
11-02-2006 · EurekAlert!
Genetic analysis of an obscure, worm-like creature retrieved from the depths of the North Atlantic has led to the discovery of a new phylum, a rare event in an era when most organisms have already been grouped into major evolutionary categories.
