Trotting With Emus To Walk With Dinosaurs:

One way to make sense of 165-million-year-old dino tracks may be to hang out with emus, say paleontologists studying thousands of dinosaur footprints at the Red Gulch Dinosaur Tracksite in northern Wyoming. Because they are about the same size, walk on two legs and have similar feet, emus turn out to be the best modern version of the enigmatic reptiles that once trotted along a long-lost coastline in the Middle Jurassic.

Grape Seed Extract Halts Cell Cycle, Checking Growth Of Colorectal Tumors In Mice:

Chemicals found in grape seeds significantly inhibited growth of colorectal tumors in both cell cultures and in mice, according to researchers who have already demonstrated the extract’s anti-cancer effects in other tumor types.

Hive Mentality: Researchers Create Buzz Over Social Behavior Genetics:

Though you may not be able to teach an old dog new tricks, Arizona State University researchers have found that evolution may have taught old genes new tricks in the development of social behavior in honeybees. The genetic basis of social behavior is being deciphered through the efforts of ASU researchers and their work with the honeybee, Apis mellifera.

Social Amoebas’ Family Tree Reveals Evolutionary Clues:

The full family tree of the species known as social amoebas has been plotted for the first time — a breakthrough which will provide important clues to the evolution of life on earth.

Flight of the Bumblebee: Flower Choice Matters:

Bees play a vital role in the pollination of native wildflowers, and UWM researchers are studying how invasive species interfere with seed production in these native plants.

New Web-based System Leads To Better, More Timely Data:

After two years of work, an innovative project using web-based technologies to speed researcher access to a large body of new scientific data has demonstrated that not only access to but also the quality of the data has improved markedly. The data-entry process for the web-enabled ThermoML thermodynamics global data exchange catches and corrects data errors in roughly ten percent of journal articles entered in the system.

Global Warming And Your Health:

Global warming could do more to hurt your health than simply threaten summertime heat stroke, says a public health physician. Although heat-related illnesses and deaths will increase with the temperatures, climate change is expected to also attack human health with dirtier air and water, more flood-related accidents and injuries, threats to food supplies, hundreds of millions of environmental refugees, and stress on and possible collapse of many ecosystems that now purify air and water.

Let’s Divide: How Daughter Cells Get Their Share Of Genetic Material:

When cells divide, control mechanisms ensure that the genetic material, in other words the chromosomes, is correctly distributed to the daughter cells. Researchers at the Max Planck Institute for Molecular Genetics in Berlin have now explained the molecular principles of these control processes.

Brain Research Supports Drug Development From Jellyfish Protein:

With the research support from the University of Wisconsin-Milwaukee, a Wisconsin biotech company has found that a compound from a protein found in jellyfish is neuroprotective and may be effective in treating neurodegenerative diseases.

Michigan State Researcher Traces The Evolution Of Honey Bee Gender:

A first-of-its-kind evolutionary strategy discovered among invertebrate organisms — or honey bees — shows how a complex genetic mechanism determines gender and maximizes gene transmission to the next generation of several bee species.
