Students Navigating The Hudson River With Hydrogen Fuel Cells
September 30, 2009
A group of ambitious Rensselaer students will soon sail up the Hudson River, propelled by pollution-free hydrogen fuel cells and a clear vision for a cleaner, greener future.
Their boat, the 22-foot New Clermont, is fit with a pair of 2.2-kilowatt fuel cell units. With a crew of three, the ship will launch from Pier 84 in Manhattan on September 21 and cruise at a cool 6 mph to arrive in Troy on the evening of September 25. The group is planning to make several stops along the way, showing off their one-of-a-kind boat, speaking with other green-minded individuals, and talking about the many environmental and potential economic benefits of building out the nation’s hydrogen economy.
“At its core, the New Clermont Project is about awareness. It’s a fun way to teach people about hydrogen energy,” said doctoral student William Gathright, who founded the group in early 2009. “We’re high-tech environmentalists. We want to share our vision of a time when people can take a pleasure cruise on their boat, or drive to the store, without leaving a trail of pollution and toxins behind them. We hope to inspire and challenge them to think of ways of making that vision a reality.”
Improving Stem Cell Techniques Using Protein Found In Moss
September 30, 2009
Hikers know that moss on a tree trunk always points north. According to new research by Israeli and German scientists, this ancient plant may also provide a new “compass” for stem cell research, telling scientists how better to program stem cells for medical purposes.
Dr. Nir Ohad of Tel Aviv University’s Department of Plant Sciences and Prof. Ralf Reski of the University of Freiburg have discovered a new use for the Polycomb group proteins (PcG) found in moss. They reported their findings recently in the journalDevelopment. PcG proteins play an important role in telling stem cells how to develop, they believe. The research is being funded by the German-Israeli Foundation.
Moss is a kind of plant that shares basic development processes with those found in humans. “We may not have found the switch that turns stem cells into tissue,” comments Dr. Ohad, “but we have found a key component which makes this switch work.”
Stopping the runaway gene
In their new paper, the researchers describe an ancient mechanism that alters the way DNA organizes inside the cell nucleus, which in turn, affects gene expression. This finding has important implications in stem cell therapies, which can go awry if implanted stem cells aren’t reprogrammed properly.
