Prostate cancer drug extends life

The new trial demonstrates that patients that take the new drug extend their life with four months. The new discovered drug seems to ease the pain in most of cases.
The drug named Zytiga, was discovered by British scientists at the Institute of Cancer Research (ICR). Zytiga can be applied in up to 80% of cases with aggressive drug-resistant prostate cancer.
'We are thrilled that a drug discovered at The Institute of Cancer Research has been proven to significantly extend life for many men, giving doctors a valuable new treatment option.' said professor Johann de Bono from the ICR and The Royal Marsden, chief trial investigator and lead author.

Astronomers unveil new 3D map of the universe

Astronomers have developed the most concluding 3D representation of the close universe up to now. Using high resolution telescopes they evaluated distances to a whopping 45,000 galaxies out to a length of 380 million light-years. Contrary to the known Sloan Digital Sky Survey, which represented just a parcel of the sky, the modern 2MASS Redshift Survey addresses 95% of encircling space, skipping only the area near the plane of our own galaxy, where the Milky Way System interference the view of remote objects. In the map, color ciphers for distance: purplish dots are close galaxies; red dots are remote ones. The new representation of the near universe will assist stargazers to interpret and explain the movement of the Milky Way, which is seemingly being drove by the gravity of adjacent groups and clusters of galaxies.

3D Solar Cell with Improved Efficiency By 80 Percent

Men of science at the United States of America section of Energy’s Oak Ridge National Laboratory have produced a 3D photovoltaic cell which could rise PV light-to-energy conversion rates by 80%.

Generally, when sunlight hits the surface of a solar board and is assimilated by solar cells, a few of the charge produced by solar photons gets pinned by natural faults in the bulk materials that comprise the strata of the PV cell, consequent in a deprivation of final electricity output.

The scientists focused on optimising this energy.

"To solve the entrapment problems that reduce solar cell efficiency, we created a nanocone-based solar cell, invented methods to synthesize these cells and demonstrated improved charge collection efficiency," Xu said.

Oak Ridge’s 3D solar cell applies zinc-oxide n-type nanocenes to suffice a model for channeling electrons. A p-type ground substance of crystalline Cd telluride functions as the main photon absorber medium.
