Superatoms mimic elements: Research gives new perspective on periodic table

A team of researchers at Penn State has discovered that certain combinations of elemental atoms can mimic the electronic signatures of other elements. By examining photoelectron spectroscopy data, they found similarities between titanium monoxide and nickel, zirconium monoxide and palladium, and tungsten carbide and platinum.

NRC rewards Penn State nuclear engineering efforts

The Nuclear Regulatory Commission has awarded Penn State's nuclear engineering program nearly $1 million to boost nuclear education and expand the workforce. The funding will support a radiochemistry education program with a new laboratory course providing hands-on experience for students.

Fear of anxiety linked to depression in above-average worriers

Researchers found that anxiety sensitivity significantly predicted depression symptoms in above-average worriers. The fear of cognitive dyscontrol and publically observable anxiety symptoms specifically correlated with depression. Understanding this link may lead to new depression treatments by addressing anxiety sensitivity.

Longer toes, unique ankle structure aid sprinters

Researchers found that sprinters have significantly shorter lever arms in their ankles compared to non-sprinters. This allows muscles to produce greater force without sacrificing speed. The study suggests that a unique foot structure is essential for sprinting success, with longer toes providing an additional advantage.

Glaciers subject of 3 Penn State grants

Researchers aim to correlate seismic activity with glacier slip using pump tests and measurements of natural seismicity. The projects focus on stability of ice stream grounding zones and role of active subglacial lakes in ice sheet loss.

Global warming cycles threaten endangered primate species

Researchers analyzed global warming's impact on four New World monkey species, finding a significant drop in their populations during climate fluctuations. The team used statistical models to investigate how food resources and tree responses related to temperature and rainfall patterns.

ConocoPhillips, Penn State award energy prize

Scott Anderson of Palm Beach, Fla., and his team won the 2009 ConocoPhillips Energy Prize with their ECO-Auger, a hydrokinetic machine harnessing tidal currents for renewable electric energy. The prize recognizes innovative ideas to create a more secure energy future.

Penn State receives National Intelligence award

Penn State's College of Information Sciences and Technology has received a two-year, $1 million grant from the Office of the Director of National Intelligence to further its research in areas related to national security. The award aims to produce students who can become leaders in the U.S. intelligence community.

Machines can't replicate human image recognition, yet

Researchers at Penn State have found that machines are unable to recognize distorted images like humans can. This limitation may be overcome in the future as computer programs harness large volumes of online data for knowledge generation and automatic recognition.

Fossil plants bring Wilf distinguished speaker honor

Peter Wilf, a renowned paleobotanist, has been awarded the prestigious Distinguished Speaker honor by the Paleontological Society. His research on ancient plants and terrestrial ecosystems will be showcased through three lectures, shedding light on biodiversity, climate change, and extinction.

Daily temperature shifts may alter malaria patterns

Researchers found that daily temperature fluctuations significantly impact malaria parasite growth and transmission rates. In areas with cooler temperatures, a fluctuation of 45 degrees Fahrenheit reduces the parasites' incubation period, making them infectious nearly two weeks earlier.
