Turning pathogens against each other to prevent drug resistance
Turning pathogens against each other to prevent drug resistance 11 December 2017Limiting a much-needed resource could pit pathogens against one another and prevent the emergence of drug resistance.
Mathematical model mimics melanoma
Mathematical model mimics melanoma 30 November 2017Cancer cells’ ability to tolerate crowded conditions may be one key to understanding tumor growth and formation, according to a mathematical model that has been applied to cancer cell growth for the first time.
Flies' disease-carrying potential may be greater than thought, researchers say
Flies' disease-carrying potential may be greater than thought, researchers say 28 November 2017A new study adds further proof to the suspicion that houseflies and blowflies carry and spread a variety of species of bacteria that are harmful to humans.
Experiment Near South Pole Reveals How Earth Blocks High-Energy Particles Produced by Nuclear Reactions
Experiment Near South Pole Reveals How Earth Blocks High-Energy Particles Produced by Nuclear Reactions 22 November 2017For the first time, a science experiment has measured Earth's ability to absorb neutrinos -- the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. The experiment was achieved with the IceCube detector, an array of 5,160 basketball-sized sensors frozen deep within a cubic kilometer of very clear ice near the South Pole. The IceCube collaboration includes Penn State physicists.
Sky-high observatory sheds light on origin of excess anti-matter: New study excludes nearby pulsars, points to dark matter as possible culprit
Sky-high observatory sheds light on origin of excess anti-matter: New study excludes nearby pulsars, points to dark matter as possible culprit 16 November 2017The High-Altitude Water Cherenkov (HAWC) Observatory in Mexico, built and operated by an international team that includes Penn State scientists, has captured the first wide-angle view of very-high-energy light emanating from two rapidly spinning stars. The fresh perspective on these stellar neighbors casts serious doubt on one possible origin for a mysterious excess of particles near Earth.
New quest to map stars and galaxies across the entire sky
New quest to map stars and galaxies across the entire sky 16 November 2017The Alfred P. Sloan Foundation has announced a $16 million grant to support the next generation of the Sloan Digital Sky Survey (SDSS-V) -- a project including Penn State scientists that is one of the most successful and influential efforts to map the universe in the history of astronomy.
Survival of the least-fit: antiviral drug selectively targets the nastiest viruses
Survival of the least-fit: antiviral drug selectively targets the nastiest viruses 08 November 2017An antiviral drug that inhibits a virus' replication machinery selectively targets the most-aggressive viruses, according to new research that looked at the infection of individual cells by a virus and the consequence of antiviral intervention.
Cryo-electron microscope to bring life sciences and materials sciences together
Cryo-electron microscope to bring life sciences and materials sciences together 06 November 2017A new cryo-electron microscope, cryo-EM, that is also a spectrometer will bring life science methods together with materials science practices together to improve both fields and share methods across disciplines.
Astronomers discover sunscreen snow falling on hot exoplanet
Astronomers discover sunscreen snow falling on hot exoplanet 26 October 2017Astronomers at Penn State have used the Hubble Space Telescope to find a blistering-hot giant planet outside our solar system where the atmosphere "snows" titanium dioxide -- the active ingredient in sunscreen.
Mimicking biological process, hydrogel signals and releases proteins
Mimicking biological process, hydrogel signals and releases proteins 26 October 2017An artificial system using a DNA-laced hydrogel can receive a chemical signal and release the appropriate protein, according to Penn State researchers. Further stimulation by the chemical signal continues to trigger a response.
Identifying the mechanism for a new class of antiviral drugs could hasten their approval
Identifying the mechanism for a new class of antiviral drugs could hasten their approval 24 October 2017New research shows that a new class of antiviral drugs works by causing the virus’ replication machinery to pause and backtrack, preventing the virus from efficiently replicating.
Exploring how herpes simplex virus changes when passed between family members
Exploring how herpes simplex virus changes when passed between family members 20 October 2017A new study explores how herpes simplex virus might change when passed from one individual to another, information that may prove useful in future development of therapeutics and vaccines.
Renewable resource: sulfur is used, replenished to produce lipoic acid
Renewable resource: sulfur is used, replenished to produce lipoic acid 19 October 2017New research shows how a protein is consumed and then reconstituted during the production of lipoic acid, a compound required by our bodies to convert energy from food into a form that can be used by our cells.
Two-dimensional materials gets a new theory for control of properties
Two-dimensional materials gets a new theory for control of properties 19 October 2017Desirable properties including increased electrical conductivity, improved mechanical properties, or magnetism for memory storage or information processing may be possible because of a theoretical method to control grain boundaries in two-dimensional materials, according to Penn State materials scientists.
Gravitational waves + new clues from space reveal new way to make a black hole
Gravitational waves + new clues from space reveal new way to make a black hole 16 October 2017For the first time, two neutron stars are caught in the act of colliding
You can see that from here: New telescope attachment allows ground-based observations of new worlds to rival those from space
You can see that from here: New telescope attachment allows ground-based observations of new worlds to rival those from space 05 October 2017A new, low-cost attachment to telescopes allows previously unachievable precision in ground-based observations of exoplanets -- planets beyond our solar system. With the new attachment, ground-based telescopes can produce measurements of light intensity that rival the highest quality photometric observations from space.
Penn State LIGO scientists celebrate 2017 Nobel Prize in Physics
Penn State LIGO scientists celebrate 2017 Nobel Prize in Physics 03 October 2017Penn State scientists and students on the Laser Interferometer Gravitational-Wave Observatory team (LIGO) are celebrating three LIGO leaders who have been honored today with the 2017 Nobel Prize in Physics.
New statistical method for evaluating reproducibility in studies of genome organization
New statistical method for evaluating reproducibility in studies of genome organization 03 October 2017A new, statistical method to evaluate the reproducibility of data from Hi-C -- a cutting-edge tool for studying how the genome works in three dimensions inside of a cell -- will help ensure that the data in these “big data” studies is reliable.
New gravitational wave hits Earth -- For the first time, 3 detectors zoom in on its location
New gravitational wave hits Earth -- For the first time, 3 detectors zoom in on its location 27 September 2017For the first time, three detectors have tracked the gravitational waves emitted by a merger of two black holes -- a critical new capability that allows scientists to more closely locate a gravitational wave's birthplace in space.
Gene associated with schizophrenia risk regulates neurodevelopment
Gene associated with schizophrenia risk regulates neurodevelopment 22 September 2017A gene associated with the risk of schizophrenia regulates critical components of early brain development, according to a new study led by researchers from Penn State University. The gene is involved in the translation of proteins from RNA and in the proliferation and migration of neurons in the brain.
