Blocking DNA repair protein could lead to targeted, safer cancer therapy
|
|
09/09/2010 01:54 AM
|
|
Researchers at the University of Pittsburgh Cancer Institute (UPCI) and the School of Medicine have discovered that inhibiting a key molecule in a DNA repair pathway could provide the means to make cancer cells more sensitive to radiation therapy while protecting healthy cells. (2010-06-02)

NASA's Swift Catches 500th Gamma-ray Burst
|
|
09/09/2010 01:54 AM
|
|
In its first five years in orbit, NASA's Swift satellite has given astronomers more than they could have hoped for. Its discoveries range from a nearby nascent supernova to a blast so far away that it happened when our universe was only 5 percent of its present age. (2010-04-20)

UCI astrophysicists cast doubt on link between excess positrons and dark matter
|
|
09/09/2010 01:54 AM
|
|
Astrophysicists are looking everywhere -- inside the Large Hadron Collider, in deep mines and far out into space -- for evidence of dark matter, which makes up about 25 percent of the energy density of the universe. (2010-04-16)

Fermi maps an active galaxy's 'smokestack plumes'
|
|

|
|
If our eyes could see radio waves, the nearby galaxy Centaurus A (Cen A) would be one of the biggest and brightest objects in the sky, nearly 20 times the apparent size of a full moon. (2010-04-02)

|
|
Time taken to detect brain tumours could soon be significantly reduced thanks to an ongoing pioneering project led by the University of Liverpool with the Nuclear Physics Group and Technology departments at the Science and Technology Facilities Council (STFC) at Daresbury Laboratory. (2010-03-04)

NASA's Fermi probes 'dragons' of the gamma-ray sky
|
|

NASA's Fermi Closes on Source of Cosmic Rays
|
|
09/09/2010 01:54 AM
|
|
New images from NASA's Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light. The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles -- cosmic rays. (2010-02-17)

Rare earth metal enhances phosphate glass
|
|
09/09/2010 01:54 AM
|
|
Adding cerium oxide to phosphate glass rather than the commonly used silicate glass may make glasses that block ultraviolet light and have increased radiation damage resistance while remaining colorless, according to Penn State researchers. (2009-12-16)

Cosmic rays hunted down
|
|
09/09/2010 01:54 AM
|
|
A thin rain of charged particles continually bombards our atmosphere from outer space. The mysterious particles were first detected 100 years ago but until 10 years ago when a new type of telescope began to come online physicists weren't sure where the "cosmic rays" came from or how they were generated.
