Cells that Can Destroy Leukemia developed by US Scientists

  • U.S. scientists developed cells that can destroy leukemia in three weeks
  • That could lead to new and effective treatments for deadly blood cancer
  • A new engineering technique involving leukemia patients treated with their own T cells
  • T cells: A type of white blood cells that were genetically modified to target and destroy tumors within the patient’s body
  • White blood cells are unable to distinguish tumor cells from healthy tissue, allowing cancer to spread out of control
  • To overcome this problem, scientists inserted a protein called chimeric antigen receptor on white blood cells so that they can attack tumor cells
  • Inserted protein will bind with another protein called CD19 that is present in Leukemia tumour cells
  • This results in the proliferation of T cells

TrES-2b (or Kepler-1b): Coal-Black Alien Planet Is Darkest Ever Seen

  • TrES-2b (or Kepler-1b): An extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away
  • The planet has been identified in 2011 as the darkest known exoplanet, reflecting less than 1% of sunlight
  • It is darker than any planet or moon in our solar system
  • NASA’s Kepler spacecraft was used by the astronomers to make this observation
  • TrES-2b was discovered in 2006 by the Trans-Atlantic Exoplanet Survey
  • It orbits its star at a distance of only three million miles. The star heats TrES-2b to a temperature of more than 1800 degrees Fahrenheit
  • TrES-2b orbits the star GSC03549, which is located about 750 light-years away
  • It can be observed near the constellation Draco


TrES-2b is the darkest known exoplanet, reflecting less light than coal or black acrylic paint.It is not clear why the planet is so dark. One reason might be a lack of reflective clouds like those that make brilliant Jupiter, due to the proximity TrES-2b to its parent star and therefore high temperature. Another reason could be the presence in the atmosphere of chemicals that absorb light such as sodium vaporized titanium oxide or potassium gas.
