Discovered: Why warm galaxies stop birth of new stars
Discovered: Why warm galaxies stop birth of new stars 25 May 2016Today, astronomers from the Sloan Digital Sky Survey (SDSS), including scientists at Penn State University, are announcing the discovery of a new class of galaxies called "red geysers." These galaxies harbor supermassive black holes with winds that produce a mysterious kind of "galactic warming" that, over the last few billion years, has turned huge numbers of galaxies into deserts devoid of fresh young stars.
New targets for vaccines identified on the surface of the malaria parasite
New targets for vaccines identified on the surface of the malaria parasite 23 May 2016Dozens of potential new protein targets for malaria vaccines have been identified and characterized on the surface of the transmitted sporozoite stage of the malaria parasite. The research also demonstrates for the first time that some proteins on the surface of the parasite have sugar additions that could cloak them from the human immune system. A paper describing the research by a collaboration of scientists from Johns Hopkins University; the Center for Infectious Disease Research in Seattle, Washington; the Institute for Systems Biology in Seattle, Washington; Harvard Medical School; and Penn State University, is available online in the April 29, 2016 issue of the journal PLOS Pathogens.
