UM171: New Molecule Allows For 10X Increase In Adult Stem Cell Transplants

UM171: New Molecule Allows For 10X Increase In Adult Stem Cell Transplants

Sep 18 2014 | comment(s)

Investigators have announced discovery of a new molecule, the first of its kind, which allows for the multiplication of stem cells in a unit of cord blood. Umbilical cord blood contains adult stem cells used for transplants aimed at curing a number of blood-related diseases, including leukemia, myeloma and lymphoma.

For many patients this therapy comprises a treatment of last resort. 

Even One Dose Of Antidepressant Dramatically Changes The Brain

Even One Dose Of Antidepressant Dramatically Changes The Brain

Even a single dose of  the commonly prescribed antidepressant SSRI (serotonin reuptake inhibitor) is enough to produce dramatic changes in the functional architecture of the human brain. Brain scans taken of people before and after an acute dose of SSRI reveal changes in connectivity within three hours, according to results in Current Biology.

Leukemia's Waterloo: The Battle For Cell Production

Leukemia's Waterloo: The Battle For Cell Production

Sep 18 2014 | comment(s)

To fight leukemia, we have to fight on its terms, and that means understanding the nature of the fight for superiority between mutated genes and normal genes, according to a paper that investigated Acute Myeloid Leukemia to understand why leukemic cells are not able to develop normally into mature blood cells.

Stem cells in the bone marrow generate billions of different blood cells each day. The process resembles a production line with genes acting as regulators to control each step of the blood formation. Leukemia arises when the DNA encoding regulators in the stem cells is changed by a mutation. When a mutation occurs in the relevant regulator genes, the finely balanced order of the production line is disrupted with drastic consequences. 

Tropical Fish Devastate Mediterranean Ecosystems

Tropical Fish Devastate Mediterranean Ecosystems

Tropical rabbitfish have devastated algal forests in the eastern Mediterranean Sea and pose a major threat to the entire Mediterranean basin if their distribution continues to expand as the climate warms, according to a new study
in the Journal of Ecology.

The members of the team surveyed more than 1000 kilometers of coastline in Turkey and Greece, where two species of rabbitfish have become dominant since they moved into the region via the Suez Canal.

Hurricane Polo still appears rounded in imagery from NOAA's GOES-West satellite today at 10:15 a.m. EDT  but forecasters expect that to change.

The image showed thunderstorms wrapping tightly around the center of the storm while one broken band of thunderstorms extended to the northwest, while the other appeared on the eastern side of the center and paralleled the southern Mexican coastline.

Polo presents a threat to the coast of southwestern Mexico's coastline. A Tropical Storm Warning is in effect for Punta San Telmo to Playa Perula and a Tropical Storm Watch is in effect for west of Playa Perula to Cabo Corrientes.

Mysterious 1808 Eruption - The Real Cause Of The Coldest Decade Of The Last 500 Years

Mysterious 1808 Eruption - The Real Cause Of The Coldest Decade Of The Last 500 Years

Sep 18 2014 | comment(s)

The Tambora volcanic eruption in 1815 is famous for its impact on climate worldwide. As a result, the year 1816 was given memorable names such as 'Eighteen-Hundred-and-Froze-to-Death', the 'Year of the Beggar' and the 'Year Without a Summer' because of cold weather and unseasonable frosts, crop failure and famine across Europe and North America. 

Some even claim the conditions inspired literary works such as Byron's 'Darkness' and Mary Shelley's Frankenstein.
