Named after Saint Thomas of Villanova, the school is the oldest Catholic university in the Commonwealth of Pennsylvania.
Founded in 1842 by the Order of Saint Augustine, the university traces its roots to old Saint Augustine’s Church, Philadelphia, which the Augustinian friars founded in 1796, and to its parish school, Saint Augustine’s Academy, which was established in 1811. U.S. News & World Report lists Villanova as a “more selective” regional university and ranks it as the best regional university in the North.
Researchers develop a way to stop ransomware
Ransomware – what hackers use to encrypt your computer files and demand money in exchange for freeing those contents – is an exploding global problem with few solutions, but a team of University of Florida researchers says it has developed a way to stop it dead in its tracks.
The answer, they say, lies not in keeping it out of a computer but rather in confronting it once it’s there and, counterintuitively, actually letting it lock up a few files before clamping down on it.
“Our system is more of an early-warning system. It doesn’t prevent the ransomware from starting … it prevents the ransomware from completing its task … so you lose only a couple of pictures or a couple of documents rather than everything that’s on your hard drive, and it relieves you of the burden of having to pay the ransom,” said Nolen Scaife, a UF doctoral student and founding member of UF’s Florida Institute for Cybersecurity Research.
Scaife is part of the team that has come up with the ransomware solution, which it calls CryptoDrop.
Developing an efficient way to freeze and store living tissues could transform many aspects of medical care and research
Developing an efficient way to freeze and store living tissues could transform many aspects of medical care and research, but ice crystallization often occurs within cells during such cryopreservation procedures, leading to cell death. In the November 5 issue of the Biophysical Journal, a Cell Press publication, researchers report that they have gained new information about the processes that are responsible for promoting the freezing of cells within tissues. This knowledge may ultimately lead to novel approaches for preventing tissue injury during cryopreservation.
A long-standing obstacle to avoiding tissue damage during freezing is that when cells are joined together within tissues, individual cells are more likely to crystallize than if the cells are kept apart. “In tissues, ice crystals are thought to be able to grow through membrane channels called gap junctions, thus allowing ice to easily propagate from cell to cell,” explains senior author Dr. Jens Karlsson, of the Department of Mechanical Engineering at Villanova University. “But the results of the present study indicate that the mechanism of tissue cryo-injury is much more complex than was previously thought.”
