DNA study
clarifies relationship between polar
bears and brown bears |
 |
At the end of the last ice age, a
population of polar bears was stranded
by the receding ice on a few islands in
southeastern Alaska. Male brown bears
swam across to the islands from the
Alaskan mainland and mated with female
polar bears, eventually transforming the
polar bear population into brown bears.

Gene therapy reprograms scar
tissue in damaged hearts into healthy heart muscle
 |
A cocktail of
three specific genes can reprogram cells
in the scars caused by heart attacks
into functioning muscle cells, and the
addition of a gene that stimulates the
growth of blood vessels enhances that
effect, said researchers from Weill
Cornell ...

Joslin researchers identify important
factor in fat storage and energy metabolism |
 |
As part of their ongoing research
on the physiologic factors that
contribute to the development of
obesity, Joslin Diabetes Center
scientists have identified a cell cycle
transcriptional co-regulator – TRIP-Br2
– that plays a major role in energy
metabolism and fat storage. This finding
has the potential to lead to new
treatments...

The last link in the
chain |
 |
Photosynthesis sustains
life on Earth by providing energy-rich
compounds and the molecular oxygen that
higher organisms depend on. The process
is powered by sunlight, which is
captured by “biochemical solar cells”
called photosystems that are found in
plants, algae and certain types of
bacteria.
