Scientists ID Echoes of Ancient Earth

June 9, 2014 12:58 pm | by European Association of Geochemistry | News | Comments

A group of scientists believe that a previously unexplained isotopic ratio from deep within the Earth may be a signal from material from the time before the Earth collided with another planet-sized body, leading to the creation of the moon. This may represent the echoes of the ancient Earth, which existed prior to the proposed collision 4.5 billion years ago.

Court Says Homeowners Can’t Sue Over Bad Water

June 9, 2014 12:47 pm | by Associated Press, Sam Hananel | News | Comments

The Supreme Court ruled today that a group of homeowners in North Carolina can't sue a company that contaminated their drinking water decades ago because a state deadline has lapsed, a decision that could prevent thousands of other property owners in similar cases from recovering damages after being exposed to toxic waste.

Chilean Lakes May Aid Search for Martian Life

June 9, 2014 7:00 am | by Inside Science News Service, Ker Than | News | Comments

Collecting samples from the volcanic lakes of northern Chile, scientists have discovered microscopic organisms preserved in long, narrow blades of gypsum salt. The discovery, according to researchers, suggests a new way to examine Mars for evidence of life.

Disappearing Hydrogels Improve Tissue Healing

June 9, 2014 7:00 am | by Univ. of Rochester | News | Comments

When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But, a technique employed by a team keeps the stem cells in place, resulting in faster and better tissue regeneration. The key is encasing the stem cells in polymers that attract water and disappear when their work is done.
