Scientists have shown for the first time that Antarctic krill show a stereotypical reaction in the presence of guano from Adélie penguins: they swim faster and make more turns over greater angles. It is unknown to what kind of water-borne chemical cues they respond, but the authors speculate that this behavior might be a universal escape response to the excreta of predators, irrespective of species.

A new analysis of data collected over three years by the Dark Energy Spectroscopic Instrument (DESI) collaboration provides even stronger evidence than the group’s previous datasets that dark energy, long thought to be a “cosmological constant,” might be evolving over time in unexpected ways. Dr. Mustapha Ishak-Boushaki, professor of physics at The University of Texas at Dallas, is co-chair of the DESI working group that interprets cosmological survey data gathered by the international collaboration.

A grant to Wayne State University from the National Science Foundation (NSF) is opening new doors for researchers and students to explore the future of autonomous vehicles, machines and drones.

Research by the Atacama Cosmology Telescope collaboration has put the standard model of cosmology through a rigorous new set of tests and show it to be remarkably robust. The new images of the early universe, which show both the intensity and polarization of the earliest light with unprecedented clarity, reveal the formation of ancient, consolidating clouds of hydrogen and helium that later developed into the first galaxies and stars.

Data centers power the digital world, storing and processing the vast amounts of information that keep businesses and web-based services running. According to Wangda Zuo, Penn State professor of architectural engineering in the College of Engineering and associate director for research at the Global Building Network, the operating costs for data centers are rising. He said for data centers, cooling is often the primary expense after IT. Servers generate significant heat, requiring temperature regulation to prevent overheating and malfunctions.
