Keeping ribosomes stuck may stop virulent bacteria strain in its tracks
Compounds that stop a cellular rescue operation for stuck ribosomes may bolster the nation's defenses against biowarfare and bioterrorism, as well as create alternative antibiotics to handle increasingly resistant pathogens, according to a team of researchers.
DJs, drones and the sounds of data featured at 2016 Polar Day on March 22
The weather may be warming with spring on the horizon, but ice will be center stage at Penn State’s annual Polar Day on March 22, 2016 on the University Park campus.
Gorilla and human Y chromosomes are highly similar, new method reveals
A new, less expensive, and faster method has been developed to determine the DNA sequence of the male-specific Y chromosome in the gorilla.
Data-sharing video library aids developmental studies
The first large-scale, open data-sharing video library is expanding at a rapid pace, providing developmental researchers at Penn State and across the world unprecedented access to data in a rich, new way.
Demirel receives proof-of-concept grant
Melik Demirel, professor of engineering science and mechanics is one of four researchers receiving a QED Proof-Of-Concept grant from the University City Science Center in Philadelphia.
Fruits, vegetables, "farm-to-fork continuum" vital to cancer prevention
After decades of research aimed at improving the yield, appearance and safety of fruits, vegetables and grains, it's time to focus science on the health benefits those foods can provide, according to a cancer researcher in Penn State's College of Agricultural Sciences.
Impact of climate change on parasite infections depends on host immunity
New research demonstrates how climate change and the immune reaction of the infected individual can affect the long-term and seasonal dynamics of parasite infections.
Penn State harnessing research muscle to fight infectious diseases
The Center for Infectious Disease Dynamics (CIDD) brings a cross-disciplinary approach to the study of infectious diseases.
Project aims to improve learning in young people with Down Syndrome
Children with Down Syndrome face many unique challenges, including being able to communicate effectively as they enter into their school years. A new Penn State study is looking to improve communications aids to better meet their academic and social needs.
Discovered: How to unlock inaccessible genes
An international team of biologists has discovered how specialized enzymes remodel the extremely condensed genetic material in the nucleus of cells in order to control which genes can be used.
What dose of medication is best to prevent the evolution of drug resistance?
A new model shows that the standard practice of treating infections with the highest tolerable dose of anti-microbial medications may not be best for preventing the evolution of drug resistance in all cases.
Acoustic tweezers move cells in three dimensions, build structures
Acoustic tweezers that can move single cells in three dimensions using surface acoustic waves without touching, deforming or labeling the cells are possible, according to a team of engineers.
Conflict among honey bee genes supports theory of altruism
Using modern genetic approaches, a team of researchers has provided strong support for the long-standing, but hotly debated, evolutionary theory of kin selection, which suggests that altruistic behavior occurs as a way to pass genes to the next generation.
Discovery of a new drug target could lead to novel treatment for severe autism
Penn State scientists have discovered a novel drug target and have rescued functional deficits in human nerve cells derived from patients with Rett Syndrome, a severe form of autism-spectrum disorder. The research, led by Gong Chen, professor of biology and the Verne M. Willaman Chair in Life Sciences at Penn State, could lead to a new treatment for Rett Syndrome and other forms of autism-spectrum disorders.
Pill that targets gut receptor treats fatty liver disease, obesity in mice
A bile acid that can turn off a receptor in the gut has prevented and reversed fatty liver disease in mice, according to an international team of researchers. The compound may help treat certain metabolic disorders, such as Type 2 diabetes and obesity, as well.
Researchers receive $10.2 million to study new malaria-prevention method
In collaboration with partners in Europe and Africa, researchers at Penn State have received a five-year, $10.2-million grant from the Bill & Melinda Gates Foundation to investigate a new method for preventing the transmission of malaria.
New $4.4 million research project targets obesity in Pennsylvania
A deeper understanding of the causes of obesity, and improved treatments for obesity and many of its related health problems, are among the goals of a new $4.4 million, four-year research grant awarded by the Pennsylvania Department of Health to a team of scientists from Geisinger Health System, Penn State University, and the University of Pennsylvania.
Smartphones enlisted in the battle versus crop disease
Crop diseases, a major cause of famine, have always been diagnosed by visual inspection, though scientists today also use microscopes and DNA sequencing. But the first line of defense is still the keen eyes of farmers around the world, many of whom do not have access to advanced diagnostics and treatment advice.
Loss of mastodons aided domestication of pumpkins, squash
If Pleistocene megafauna -- mastodons, mammoths, giant sloths and others -- had not become extinct, humans might not be eating pumpkin pie and squash for the holidays, according to an international team of anthropologists.
The Sepia Rainbow: The fascinating story of human skin
Nina Jablonski’s focus on skin began with a request to give a lecture. It was 1991, and she and her husband and collaborator George Chaplin had recently moved from Hong Kong to take positions at the University of Western Australia.
