Pennsylvania State University, a public research university in University Park, PA, known for research in engineering, agriculture, and sciences.
Penn State researchers estimate that about 2% of the natural gas piped into Indianapolis leaks, based on nearly a decade of tower data. They say most of it likely comes from homes and other buildings, not exterior pipelines.
Reality
Penn State-led researchers built a pilot syphilis test that detects lower antibody levels and draws lines 19% to 46% stronger than comparable devices. The team says that could mean earlier interventions and fewer appointments.
Reality
Penn State researchers found guinea fowl raised with leg weights later carried the load at no added energy cost, while untrained birds used 23% more. The comparison is controlled and the groups are small, so it supports a narrow causal claim about leg loading in one species.
Reality
Penn State researchers report that 0.05% enzyme-cut lentil peptide gives nonfat yogurt mechanical texture similar to whole-milk yogurt. Removing fat makes yogurt thinner and changes its mouthfeel, so a plant additive that restores structure addresses a known cost of nonfat dairy.
Reality
Penn State-led researchers report an oxide thin film whose chemical disorder produces complex magnetic properties, in Advanced Materials. The authors say it could support faster, lower-power electronics and plan to take it to industry.
Reality
Penn State's model of a 1,000-cow dairy found co-digesting crops with manure cut break-even capital support for a digester from about 47% to as little as 4%. The figures come from a model, and even the best case still needs some grant or loan support to break even.
Reality
Penn State-led researchers list 738 bee species in Colombia's first national checklist, 246 of them new records for the country. Their estimate of roughly 1,400 species lends weight to the team's view that thin sampling explains part of the tropics' apparent bee shortfall.
Reality
Penn State researchers found Masaya's caldera sank then rose across six years of satellite radar, while its Santiago crater deflated throughout. The authors read that as two reservoirs behaving separately, something monitoring has to account for at a volcano within 21 km of 2 million people.

Penn State researchers trained a diffusion model, the method behind AI image generators, on more than 500 US river basins to forecast hourly flash-flood risk. It takes in new gauge readings without retraining, so a warning service could keep it current.
Reality
Penn State researchers moved agent attack-success rates by up to 13.21 points by renaming tools, with the attack, task and policy held fixed. The size of the shift varied by model and benchmark, so a robustness score only describes the tool names and schemas it was measured on.
Reality
Penn State's team won $1 million from the Department of Energy to track samarium, europium and tellurium in molten salt reactors and recycling systems. The money pays for lab measurement of how those elements behave in salt, the step any recycling or corrosion fix has to start from.
Reality
Penn State engineers are surface-modifying sterile-filtration membranes to remove microbes from injectable drugs, in work published in Biotechnology Journal. Doctoral candidate Shreya Kapila's own test for a new filter is that it removes organisms while leaving little of an expensive drug behind in the membrane.
Reality
NASA's Swift observatory, in orbit since 2004, will re-enter by year's end after the Katalyst spacecraft sent to boost it developed faults in orbit. NASA now presents the year-long effort as practice for fast commercial satellite servicing.
Reality
A Penn State-led team says it imaged the shallow subsurface using thunderquakes recorded on a 4 km campus telecom cable, with no seismic source and no sensor array deployed.

Penn State found age reshaped the resistance genes of 320 broiler chickens far more than antibiotic, probiotic or essential-oil feed did. With the antibiotic diet also flat, the three-week trial cannot show the alternatives reduce resistance.
Reality
Penn State researchers suppressed skin bacteria on two Brazilian frog species with antibiotics, and only one of the two then showed more disease from the chytrid fungus. The team also screened about 700 bacterial strains to link each one's identity to its antifungal effect.
Reality
A Form D filed on September 17 counts an earlier $150,000 SAFE conversion inside that total, and what it funds is a physics-based twin that recommends cooling setpoints an operator still has to accept.
Reality
Penn State researchers built a test, called ELCA, that reacts to effector proteins made only by living bacteria, giving a signal for an active infection at about the cost of a standard ELISA. It is a proof of concept on one crop pathogen.
Reality
Penn State walked the bromine-to-iodide ratio across six metal-halide films to aim the bandgap at indoor wavelengths. The stability run that followed was done under light many times brighter than an office ceiling.
Reality
Grab bottles and passive in-stream samplers, run side by side for two growing seasons, produced records that disagree about where contamination concentrates and when it peaks. Penn State's team says a program needs both.
