4 faculty receive WUN support for global research partnerships

Four Penn State faculty have been selected to participate in collaborative projects with international partners on various topics, including ocean acidification, earth surface sedimentary flow processes, climate change adaptation, and public health. The partnerships aim to address global issues and promote interdisciplinary research.

Happy children make happy adults

A new study found that teenagers rated positively by their teachers had higher levels of well-being later in life, including higher work satisfaction and more frequent social activities. Happy children were also less likely to develop mental disorders throughout their lives.

Viral infection not responsible for exacerbation of lung disease in most patients

Researchers found no evidence of viral infection causing acute exacerbation of idiopathic pulmonary fibrosis (IPF) in most patients. Instead, torque teno virus (TTV) was detected in lung fluid samples from a small percentage of IPF patients, suggesting it may be a marker of lung injury rather than a cause.

Brain imaging provides window into consciousness

Researchers use fMRI to probe for higher-level cognitive functioning in severely brain-injured patients, finding a wide variation in response capabilities. The study suggests that no bedside exam can accurately assess cognitive function in these patients, highlighting the need for further exploration and understanding.

Model for managing asthma in preschoolers leads to dramatic drop in ER visits and hospitalizations

A new asthma management program for preschoolers, developed by Columbia University's Mailman School of Public Health, has shown dramatic results in reducing emergency room visits and hospitalizations. The program, which includes educational activities for parents and children, as well as training for healthcare providers, has led to a ...

Overfertilizing corn undermines ethanol

A new study by Rice University researchers reveals that overfertilizing corn crops for ethanol production can lead to decreased cellulose content in plant residues, making it more difficult to extract ethanol. The study suggests using less fertilizer can improve feedstock quality and alleviate environmental damage.

Enzyme cocktail could eliminate a step in biofuel process

Virginia Tech researchers have discovered an enzyme mixture that can work in the presence of toxic infused liquid biomass, eliminating the need for detoxification and reducing production costs. The enzyme cocktail increases biofuel yields by avoiding the production of by-products and synthesis of cell mass.

New research suggests that obesity and diabetes are a downside of human evolution

A new genetic discovery suggests that the loss of function in a human-specific gene called CMAH may contribute to the development of Type 2 diabetes. The study found that mice with this gene mutation developed insulin resistance and pancreatic beta cell failure, leading to decreased insulin production and impaired blood glucose control.

La Jolla Institute-led team illuminates cell pathway key to insulin resistance in Type 2 diabetes

A La Jolla Institute-led team has identified the primary cellular players in an adenosine-fueled inflammation cascade that contributes to insulin resistance. By using an adenosine receptor blocker, the team prevented the activation of macrophages, leading to improved insulin sensitivity and reduced blood sugar levels in diabetic animals.

Probiotic identified to treat ulcers

A strain of probiotic bacteria, Bifidobacterium bifidum CECT 7366, has been identified as effective in treating ulcers caused by Helicobacter pylori. The probiotic strain demonstrated significant inhibition levels against H. pylori and partially relieved damage to gastric tissue.
