U.S. economic growth slowed in the first quarter although not as sharply as initially thought, as a surge in home building and steady inventory accumulation partially offset the drag from a steep decline in business investment. Economists said strong income growth, together with signs the economy was picking up steam in the second quarter, could give the Federal Reserve the ammunition to raise interest rates as early as next month. The U.S. central bank increased rates in December for the first time in nearly a decade.
An important amino acid called glycine has been detected in a comet for the first time, supporting the theory that these cosmic bodies delivered the ingredients for life on Earth, researchers said Friday. Glycine, an organic compound contained in proteins, was found in the cloud around Comet 67P/Churyumov-Gerasimenko by the European Space Agency's probe, Rosetta, said the study in the journal Science Advances. The discovery was made using an instrument on the probe, called the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) mass spectrometer.
