- Record-breaking map of 1.2-million galaxies now ready to reveal secrets of dark energy
- 14 July 2016 — Astronomers are announcing this week the sharpest view yet of the properties of dark energy -- the force that currently is driving the accelerated expansion of the universe. "These results are a milestone in the study of the large-scale structure of the universe," said Penn State Professor Donald Schneider, who was the survey coordinator and scientific publications coordinator for the Sloan Digital Sky Survey III (SDSS-III) -- a collaboration of hundreds of scientists whose work produced the largest-ever, three-dimensional map of distant galaxies as well as one of the most precise measurements yet of dark energy.
- New clues could help scientists harness the power of photosynthesis
- 07 July 2016 — Identification of a gene needed to expand light harvesting in photosynthesis into the far-red-light spectrum provides clues to the development of oxygen-producing photosynthesis, an evolutionary advance that changed the history of life on Earth. "Knowledge of how photosynthesis evolved could empower scientists to design better ways to use light energy for the benefit of mankind," said Donald A. Bryant, the Ernest C. Pollard Professor of Biotechnology and professor of biochemistry and molecular biology at Penn State University and the leader of the research team that made the discovery.
- New, better way to build circuits for world's first useful quantum computers
- 27 June 2016 — The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. The research advance, using a 3-dimensional array of atoms in quantum states called quantum bits -- or qubits -- was made by David S. Weiss, professor of physics at Penn State University, and three students on his lab team.
