WISE Satellite Finds No Evidence for Planet X in Survey of the Sky: 07 March 2014 — After searching hundreds of millions of objects across the sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly called "Planet X," according to published scientific papers including a new study in The Astrophysical Journal authored by Kevin Luhman of the Center for Exoplanets and Habitable Worlds at Penn State University.
Water is Detected in a Planet Outside Our Solar System: 24 February 2014 — Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water, like Earth, exist throughout the universe. The team of scientists that made the discovery includes astronomers at Penn State University and other institutions. The astronomers detected the water in the atmosphere of a planet as massive as Jupiter that is orbiting the nearby star Tau Boötis. The discovery is described in a scientific paper published in the 24 February 2014 online version of The Astrophysical Journal Letters.
A Key Regulatory Protein Is Discovered To Be Essential for Malaria Parasite Transmission to Mosquitos: 23 February 2014 — Two teams have independently discovered that a single regulatory protein acts as the master genetic switch that triggers the development of male and female sexual forms (termed gametocytes) of the malaria parasite, solving a long-standing mystery in parasite biology with important implications for human health. The protein, AP2-G, is necessary for activating a set of genes that initiate the development of gametocytes -- the only forms that are infectious to mosquitos. The research also gives important clues for identifying the underlying mechanisms that control this developmental fate, determining whether or not a malaria parasite will be able to transmit the disease.
Asteroid Named for Two Penn State Students: 14 February 2014 — An asteroid that orbits the Sun every 4.83 years has been named for two students at Penn State's University Park Campus. The asteroid, first detected on 5 October 2002 in an observation by the Sloan Digital Sky Survey, has been designated TimRaySchneider. To receive an official name, an asteroid must be observed for a number of orbits so its future positions can be predicted accurately.
Nanomotors Are Controlled, for the First Time, Inside Living Cells: 10 February 2014 — For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. It's not exactly "Fantastic Voyage," but it's close. The nanomotors, which are rocket-shaped metal particles, move around inside the cells, spinning and battering against the cell membrane.
Critical Protein Discovered for Healthy Cell Growth in Mammals: 27 January 2014 — A team of researchers from Penn State University and the University of California has discovered a protein that is required for the growth of tiny, but critical, hair-like structures called cilia on cell surfaces. The discovery has important implications for human health because lack of cilia can lead to serious diseases such as polycystic kidney disease, blindness and neurological disorders.
A New, "Exceptionally Close" Exploding Star: 24 January 2014 — An exceptionally close exploding star, discovered on 21 January is the focus of observatories on Earth and in orbit, including the Swift satellite and several other NASA spacecraft. The science and flight operations of the Swift observatory are controlled by Penn State from the Mission Operations Center on the University Park campus. The Swift observatory was the first to take a look at this supernova.
A New Pathway for Neuron Repair is Discovered: 09 January 2014 — Penn State University molecular biologists have discovered a brand-new pathway for repairing nerve cells that could have implications for faster and improved healing. The researchers describe their findings in a paper titled "Dendrite injury triggers DLK-independent regeneration," which will be published in the 30 January 2014 issue of the journal Cell Reports. These findings demonstrate that dendrites, the component of nerve cells that receive information from the brain, have the capacity to regrow after an injury.
Size of the Universe Now Measured to Within One Percent: 08 January 2014 — The distance to a set of 1.2 million galaxies that are more than six billion light years away from Earth has been measured to an accuracy of one percent, scientists will announce during a press conference on Wednesday, 8 January 2014. The measurements place new constraints on the properties of the "dark energy" that is thought to permeate empty space and to cause the universe's expansion to accelerate over time, report the research team from the Baryon Oscillation Spectroscopic Survey (BOSS), which includes astronomers at Penn State University.
X-Ray Factory Revealed in the Center of Our Galaxy: 08 January 2014 — A seven-year campaign to monitor the center of our galaxy with NASA's Swift spacecraft has more than doubled the number of bright X-ray flares observed from our galaxy's central black hole and has led to the discovery of a rare type of neutron star called a "magnetar." Jamie Kennea, a Penn State astronomer, will present the findings during a press conference on 8 January 2014 at a meeting of the American Astronomical Society. The science and flight operations of the Swift observatory are controlled by Penn State from the Mission Operations Center on the University Park campus.
The Origin of Flowers: DNA Study Provides Insight into the Evolution of Food Crops and Other Flowering Plants: 19 December 2013 — New light has been shed on a major event in the history of life on Earth -- the origin of all major food crops and all other flowering plants -- by the publication of the newly sequenced genome of the Amborella plant. The research addresses the question of why flowers suddenly proliferated on Earth millions of years ago. A paper by the Amborella Genome Sequencing Project, which includes Penn State scientists and Penn State students, will be published by the journal Science in the 20 December 2013 issue.
Brain Repair after Injury and Alzheimer's Disease: In vivo reprogramming of reactive glial cells into functional neurons: 19 December 2013 — Researchers at Penn State University have developed an innovative technology to regenerate functional neurons after brain injury, and also in model systems used for research on Alzheimer's disease. The scientists have used supporting cells of the central nervous system, glial cells, to regenerate healthy, functional neurons, which are critical for transmitting signals in the brain.
DNA of Storied Plant Provides Insight into the Evolution of Flowering Plants, Study Finds: 19 December 2013 — The newly sequenced genome of the Amborella plant addresses Darwin's "abominable mystery" -- the question of why flowers suddenly proliferated on Earth millions of years ago. The genome sequence sheds new light on a major event in the history of life on Earth: the origin of flowering plants, including all major food crop species.
Marine Biologists Unmask Species Diversity in Coral Reefs: 12 December 2013 — Rising water temperatures due to climate change are putting coral reefs in jeopardy, but a surprising discovery by a team of marine biologists suggests that very similar looking coral species differ in how they survive in harsh environments. "We've found that previously unrecognized species diversity was hiding some corals' ability to respond to climate change," says Iliana Baums, associate professor of biology at Penn State University.
A Blast from Its Past Dates the Youngest Neutron-Star Binary: 04 December 2013 — X-rays streaming toward Earth from the region near a neutron star that is cannibalizing its companion star have revealed the pair to be the youngest "X-ray binary" yet known.
Ultra-Bright Gamma-Ray Burst Shakes Up Theories of Light Production in the Most Powerful Explosions: 25 November 2013 — One of the brightest gamma-ray explosions ever seen is the focus of five papers being published this week in the journals Science Express and Astrophysical Journal Letters by research teams that include Penn State Professor of Astronomy and Astrophysics David Burrows. Discovered on 27 April 2013, this gamma-ray burst, named GRB 130427A, has been the subject of intense study with advanced space observatories including NASA's Swift X-ray Telescope, for which science and flight operations are controlled by Penn State from the Mission Operations Center at the University Park campus.
New Tool Developed for Profiling Critical Regulatory Structures of RNA Molecules: 24 November 2013 — A molecular technique that will help the scientific community to analyze -- on a scale previously impossible -- molecules that play a critical role in regulating gene expression has been developed by a research team led by a chemist and a plant biologist at Penn State University. The scientists developed a method that enables more-accurate prediction of how ribonucleic acid molecules (RNAs) fold within living cells, thus shedding new light on how plants -- as well as other living organisms -- respond to environmental conditions.
Neutrinos on Ice Now the Coolest New Astronomy Tool: 21 November 2013 — A massive telescope buried in the Antarctic ice has detected 28 record-breaking, extremely high-energy neutrinos -- elementary particles that likely originate outside our solar system. The achievement, which comes nearly 25 years after the pioneering idea of detecting neutrinos in ice, provides the first solid evidence for astrophysical neutrinos from cosmic accelerators and has been hailed as the dawn of a new age of astronomy. The team researchers that detected the neutrinos with the new IceCube Neutrino Observatory in Antarctica, which includes Penn State scientists, will publish a paper describing the detections on 22 November 2013 in the journal Science.
Investigating Roles of Rare Genetic Variants in Disease: 14 November 2013 — Researchers at the Center for Systems Genomics are developing bioinformatics software to facilitate analysis of rare variation in human genome sequence data.
New Type of Black-Hole Quasar Discovered: 07 November 2013 — Like our Milky Way, every known large galaxy has at its center a supermassive black hole, some of which are surrounded by a super-bright disk of hot gas called a quasar -- but now a research team that includes Penn State astronomers has discovered a surprising new class of quasars in distant galaxies that even the most current theories had not predicted.
