Januvia Does More Harm than...?

In the news:
Andrew Pollack
May 30, 2013
New York Times
Januvia (sitagliptin) is a hypoglycemic drug, one that reduces blood sugar levels. Diabetes is a condition in which blood sugar levels can get dangerously high due to a lack of insulin, the hormone that reduces them. Januvia works by inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4). DPP-4 rapidly deactivates the incretin hormone GLP-1 (glucagon-like peptide 1), which promotes insulin release. Hence, inhibiting DPP-4 prolongs the effects of GLP-1, keeping insulin levels high.

Heinrich Rohrer dies - Father of Nanotechnology

In the news:

May 22, 2013
Heinrich Rohrer (born 1933), Swiss physicist. Rohrer studied physics at the Swiss Federal Institute (ETH) in Zurich under Pauli. He gained his PhD, in superconductivity, in 1960. In 1963 he joined IBM's Zurich Research Laboratory where his research interests included phase transitions, critical phenomena and nanomechanics. While at IBM, Rohrer and his colleague Gerd Binnig designed the scanning tunneling microscope (STM). The STM uses a fine needle with an electric potential running through it to scan the surface of an object. It is able to obtain very high magnifications, even visualizing individual atoms. Rohrer and Binnig were awarded the Nobel Prize in Physics in 1986 for this work.

SQ0657 - Kepler Space Observatory
Kepler Mission's exoplanets, artwork. NASA's Kepler Mission (not shown) is a space telescope designed to discover Earth-like planets orbiting other stars. Examples of such planets are shown here, including Earth-like planets, Martian planets, Venusian planets, Jovian planets and Saturnian planets. Kepler's 0.95-meter diameter photometer will scan 100,000 stars in the Milky Way for evidence of Earth-sized terrestrial planets that transit the star's path. The mission was launched on March 7th, 2009, and is named in honor of German astronomer Johannes Kepler. As of February 2011, over 1000 candidate planets have been discovered.

Keeling Curve Keels Over as Atmospheric Levels of CO2 Rise Above 400ppm

BE1195 - Professor Charles D. Keeling

Portrait of Professor Charles D Keeling (b.1928), the US oceanographer and climate scientist. Keeling was the first to confirm, by measurement, the gradual accumulation of carbon dioxide (CO2) in the Earth's atmosphere. The data set that shows this change is known as the "Keeling Curve". Previously, it had been thought that the excess CO2 would be absorbed by the oceans. This worldwide increase in CO2 concentration is thought to cause 'global warming', a rise in the Earth's mean temperature by the 'Greenhouse Effect'. This photograph was taken in March 1992 in Keeling's laboratory at the Scripps Institution of Oceanography, San Diego, USA.
