Student Neha Gupta, Children's Peace Prize winner, brings charity to Penn State
28 March 2016"Imagine throwing a pebble in a pond: the first ripple is small, but then you watch in awe as the ripples become larger and larger," said Neha Gupta, Penn State science student. "And just so is the impact of one person with an idea or mission that speaks to the heart." Gupta is one of the rarest kinds of students. Balancing a premedicine honors curriculum, she also runs an international charity and acts as a spokesperson for Microsoft.
Impact of climate change on parasite infections depends on host immunity
15 February 2016New research demonstrates how climate change and the immune reaction of the infected individual can affect the long-term and seasonal dynamics of parasite infections. The study, led by Penn State University scientists, assessed the infection dynamics of two species of soil-transmitted parasites in a population of rabbits in Scotland every month for 23 years. The study's results could lead to new strategies for the treatment and prevention of infections from similar parasites in humans, livestock, and wildlife.
Gravitational waves detected 100 years after Einstein's Prediction: Opens New Window on the Universe with Observation of Gravitational Waves from Colliding Black Holes
11 February 2016For the first time, scientists have observed ripples in the fabric of spacetime, called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe. This observation confirms a major prediction of Albert Einstein’s general theory of relativity, published in 1916, and opens an unprecedented new window onto the cosmos.
Some Vaccines Support Evolution of More-Virulent Viruses
27 July 2015Scientific experiments with the herpesvirus that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of severe illness. The research has important implications for food-chain security and food-chain economics, as well as for other diseases that affect humans and agricultural animals.
First Successful Lab Breeding of Rare Caribbean Coral Species
13 March 2015A rare and threatened Caribbean coral species has been successfully bred and raised in the lab for the first time by a research team whose achievement will be published in the scientific journal BMC Ecology. Penn State University Associate Professor of Biology Mónica Medina is among the three scientists on this research team. Its work provides the first photos and documentation of juveniles of this species, and could provide information to aid the conservation of coral reefs in the study area. The team plans to 'out-plant' these lab-grown juveniles in the wild, which could help populations become more resilient to climate change.
Complex nerve-cell signaling traced back to common ancestor of humans and sea anemones
16 February 2015New research shows that a burst of evolutionary innovation in the genes responsible for electrical communication among nerve cells in our brains occurred over 600 million years ago in a common ancestor of humans and the sea anemone. The research, led by Timothy Jegla, an assistant professor of biology at Penn State University, shows that many of these genes, which when mutated in humans can lead to neurological disease, first evolved in the common ancestor of people and a group of animals called cnidarians, which includes jellyfish, coral, and sea anemones. A paper describing the research is scheduled to be posted online in the Early Edition (EE) of the journal Proceedings of the National Academy of Sciences of the United States of America sometime during the week beginning February 16, 2015.
NASA's Swift Satellite Marks 10 Years of Game-changing Astrophysics: Mission Control Is at Penn State
20 November 2014On the tenth anniversary of its launch, NASA’s Swift Gamma-ray Burst Explorer -- an orbiting space observatory with major and continuing contributions from Penn State scientists -- is recognized as one of the most versatile astrophysics missions ever flown. It remains the only satellite that can precisely locate gamma-ray bursts -- the universe’s most powerful explosions. It also is the only satellite that can monitor the explosions in space across a broad range of wavelengths using multiple instruments before these powerful bursts fade from view.
In Disease Outbreak Management, Flexibility Can Save Lives and Money
21 October 2014A new approach for responding to and managing disease outbreaks is being proposed by a team of epidemiologists led by two Penn State University researchers. The team's flexible approach could save many lives and millions of dollars.
Smallest Possible Diamonds Form Ultra-thin Nanothreads
21 September 2014For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. A paper describing this discovery by a research team led by John V. Badding, a professor of chemistry at Penn State University, will be published in the 21 September 2014 issue of the journal Nature Materials.
Impact of Deepwater Horizon Oil Spill on Coral Communities Is Deeper and Broader than Predicted
28 July 2014A new discovery of two additional coral communities showing signs of damage from the Deepwater Horizon oil spill expands the impact footprint of the 2010 spill in the Gulf of Mexico. The discovery was made by a team led by Charles Fisher, professor of biology at Penn State University. A paper describing this work and additional impacts of human activity on corals in the Gulf of Mexico will be published during the last week of July 2014 in the online Early Edition of the journal Proceedings of the National Academy of Sciences.
Live Webcams: Scientists Studying Corals Damaged by Oil in the Gulf of Mexico
25 June 2014How are the corals doing now, four years after they were damaged by the Deep Water Horizon oil spill in the Gulf of Mexico? You can find out by watching live webcams and by sending messages to the scientists on a research ship that will be in the Gulf until July 4. The research expedition is led by Chief Scientist Chuck Fisher, a Penn State University professor of biology. Interact with the research crew, listen in, and watch as they explore the ocean floor. The 24/7 live webcams are on the expedition's website, Nautiluslive.org. You also can participate on Facebook (facebook.com/nautiluslive) and Twitter (@EVNautilus).
Nanomotors Are Controlled, for the First Time, Inside Living Cells
10 February 2014For 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.

Neutrinos on Ice Now the Coolest New Astronomy Tool
21 November 2013A 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.
