Super-dense Star is First Ever Found Suddenly Slowing Its Spin
Super-dense Star is First Ever Found Suddenly Slowing Its Spin 29 May 2013One of the densest objects in the universe, a neutron star about 10,000 light years from Earth, has been discovered suddenly putting the brakes on its spinning speed. The event is a mystery that holds important clues for understanding how matter reacts when it is squeezed more tightly than the density of an atomic nucleus -- a state that no laboratory on Earth has achieved. The star has a mass that is half a million times greater than that of the Earth, but a diameter only about the distance from the Penn State University Park campus to Bellefonte, PA. The discovery was made by an international team of scientists that includes a Penn State astronomer.

Record-Breaking High-Energy Particles from Space Detected by Telescope Buried in the Antarctic Ice
Record-Breaking High-Energy Particles from Space Detected by Telescope Buried in the Antarctic Ice 17 May 2013A massive telescope buried in the Antarctic ice has detected 28 extremely high-energy neutrinos -- elementary particles that likely originate outside our solar system. Two of these neutrinos had energies many thousands of times higher than the highest-energy neutrino that any man-made particle accelerator has ever produced, according to a team of IceCube Neutrino Observatory researchers that includes Penn State scientists. These new record-breaking neutrinos had energies greater than 1,000,000,000,000,000 volts or, as the scientists say, 1 peta-electron volt (PeV).
Probing Question: Do Women Dominate the Field of Forensic Science?
Probing Question: Do Women Dominate the Field of Forensic Science? 08 May 2013Exhuming corpses, analyzing bloodstained clothing, collecting "crime scene insects" (yes, maggots)...these are some of the grittier realities of life as a forensic scientist. Yet defying the stereotype that females tend to be squeamish about such things, an entire generation of young women have become entranced by the profession, inspired in part by characters such as Abby Sciuto on the television drama NCIS. In fact, they've pursued this career in such numbers that—unlike almost every other scientific discipline—one could argue that the booming field of forensic science is a female domain. Has forensic science, in fact, become a woman's field?
Gene Offers Clues to New Treatments for a Harmful Blood Clotting Disorder
Gene Offers Clues to New Treatments for a Harmful Blood Clotting Disorder 07 May 2013A gene associated with both protection against bacterial infection and excessive blood clotting could offer new insights into treatment strategies for deep-vein thrombosis -- the formation of a harmful clot in a deep vein. The gene produces an enzyme that, if inhibited via a specific drug therapy, could offer hope to patients prone to deep-vein clots, such as those that sometimes form in the legs during lengthy airplane flights or during recuperation after major surgery.

Probing Question: Are We Running Out of Helium?
Probing Question: Are We Running Out of Helium? 25 April 2013Party planners, take note: the atmosphere may become a little deflated at gala events in the future. Some scientists are sounding the alarm about the wastefulness of using helium -- a rare, non-renewable gas -- to fill party balloons. Why? As an essential resource in technologies such as medical imaging, rocket engines, and surveillance devices, it turns out that helium does a lot more than give our balloons a lift. And despite being the second most abundant element in the universe, most of our supply in the Earth’s atmosphere simply floats off into space and is lost.
Charles Lawrence to Present Marker Lectures in Astronomy and Astrophysics on 22, 24, and 25 April 2013 (101 Thomas Building, from 25 April 2013 07:00 PM to 25 April 2013 08:30 PM)
11 April 2013Charles Lawrence, senior research scientist and principal scientist at the California Institute of Technology Jet Propulsion Laboratory, will present the Russell Marker Lectures in Astronomy and Astrophysics on 22, 24, and 25 April, 2013, at the Penn State University Park Campus. The lecture series includes a presentation intended for a general audience, "Measuring the Universe," which will be held at 7:00 p.m. on Thursday, 25 April, in 101 Thomas Building.

White-Dwarf Star, Blown Apart in 1604, Now Reveals New Secrets
White-Dwarf Star, Blown Apart in 1604, Now Reveals New Secrets 08 April 2013Remnants of an exploded star have been discovered in our Milky Way galaxy by a team of scientists including astronomers at Penn State University. The "supernova remnant" was discovered during an extensive X-ray survey of our galaxy's central regions with NASA's Swift satellite, for which science and flight operations are controlled by Penn State from the Mission Operations Center on the University Park campus. A paper describing the team's findings will be published in an upcoming edition of The Astrophysical Journal.

On Twitter, Anti-Vaccination Sentiments Spread More Easily than Pro-Vaccination Sentiments
On Twitter, Anti-Vaccination Sentiments Spread More Easily than Pro-Vaccination Sentiments 04 April 2013On Twitter, a popular microblogging and social-networking service, statements about vaccines may have unexpected effects -- positive messages may backfire, according to a team of Penn State University researchers led by Marcel Salathé, an assistant professor of biology. The team tracked the pro-vaccine and anti-vaccine messages to which Twitter users were exposed and then observed how those users expressed their own sentiments about a new vaccine for combating influenza H1N1 -- a virus strain responsible for swine flu.
Autism Linked to Increased Genetic Change in Regions of Genome Instability
Autism Linked to Increased Genetic Change in Regions of Genome Instability 02 April 2013Children with autism have increased levels of genetic change in regions of the genome prone to DNA rearrangements, so called "hotspots," according to a research discovery to be published in the print edition of the journal Human Molecular Genetics. The research indicates that these genetic changes come in the form of an excess of duplicated DNA segments in hotspot regions and may affect the chances that a child will develop autism -- a behavioral disorder that affects about 1 of every 88 children in the United States, according to the Centers for Disease Control.
