To fight disease, animals, like plants, can tolerate parasites
11-06-2007 · EurekAlert!Animals, like plants, can build tolerance to infections at a genetic level, and these findings could provide a better understanding of the epidemiology and evolution of infectious disease, according to evolutionary biologists.

- Natural, soy-based substance might help fight MS, Jefferson neuroscientists find
12-12-2006 · EurekAlert!
A natural substance made from soy appears to have amazing restorative powers when given to animals with a multiple sclerosis (MS)-like disease. Using an animal model of MS, neurologists at Jefferson Medical College found that giving a substance called Bowmann-Birk Inhibitor Concentrate (BBIC) dramatically improved the animals' ability to move and walk. The scientists say the treatment’s effects may be useful in conjunction with more mainstream therapies such as beta-interferon in helping patients with MS.

- Green algae -- the nexus of plant/animal ancestry
10-11-2007 · EurekAlert!
Genes of a tiny, single-celled green alga called Chlamydomonas reinhardtii may contain scores more data about the common ancestry of plants and animals than the richest paleontological dig. This work is described in an article in the Oct. 12, 2007, issue of Science.

- Global warming and other research from UCLA summit featured in journal
12-20-2007 · EurekAlert!
Global warming and other human-caused ecological changes are outpacing the ability of species to adapt, resulting in greater threats of disease, reduced diversity in plant and animal communities, and an overall loss of natural heritage, according to research presented at a University of California, Los Angeles, summit and published in the peer-reviewed journal Molecular Ecology.

- Discovery in plants suggests entirely new approach to treating human cancers
04-04-2007 · EurekAlert!
For the first time, scientists from the University of Washington School of Medicine, Indiana University Bloomington and the University of Cambridge have determined how a plant hormone -- auxin -- interacts with its hormone receptor, called TIR1. Their report, on the cover of this week's issue of Nature, also may have important implications for the treatment of human disease, because TIR1 is similar to human enzymes that are known to be involved in cancer.

- Stanford discovery may help predict when toxoplasma can be deadly
12-14-2006 · EurekAlert!
Toxoplasma is arguably the most successful animal parasite on earth: It infects hundreds of species of warm-blooded animals, most notably half of humanity. Researchers at the Stanford University School of Medicine have identified two of the proteins critical to its ability to thrive.

- Rapid evolution of defense genes in plants may produce hybrid incompatibility
07-08-2007 · EurekAlert!
Species are kept separate in plants and animals through barriers to gene flow. However, the exact mechanisms of speciation have only been explained within the last 20 years. Dr. Detlef Weigel and colleagues found that one mechanism, hybrid necrosis, is associated with a plant defense gene. Different forms of these rapidly evolving genes in parent plants can cause autoimmune responses leading to offspring inviability and may represent a molecular pathway to speciation unique to plants

- Antarctic plants and animal life survived ice ages
09-27-2007 · EurekAlert!
Springtails, mites, worms and plant life could help solve the mystery of Antarctica's glacial history according to new research published in the journal Science this week.Scientists from British Antarctic Survey and Massey University New Zealand report that of the evolutionary history of Antarctica's terrestrial plant and animal life does not reconcile with current reconstructions of past glacial ice extent going back more than 23 million years.

- Internal clock, external light regulate plant growth
07-09-2007 · EurekAlert!
Most plants and animals show changes in activity over a 24-hour cycle. Now, for the first time, researchers have shown how a plant combines signals from its internal clock with those from the environment to show a daily rhythm of growth.

- Study of malaria parasites reveals new parasitic states
11-28-2007 · EurekAlert!
Although malaria parasites have undergone extensive laboratory study, relatively little is known about how they behave in humans to cause disease. Newly published data from a study of malaria-infected human blood reveal two biological states of the parasite Plasmodium falciparum not observed under laboratory conditions. This information may help scientists develop new strategies for treating malaria.
