Penn State

In a new study, researchers from Penn State and NASA’s Jet Propulsion Laboratory analyzed human deep space communications and found that human transmissions are frequently directed toward our own spacecrafts near Mars (lower left), the Sun, and other planets. Because planets like Mars do not block the entire signal, an extraterrestrial intelligence positioned along the path of interplanetary communications—when the planets align form their perspective—could potentially detect the spillover. This suggests that humans should look to planetary alignments outside of the solar system when searching for signatures of extraterrestrial communications.

Stone alignments revealed an ancient temple, called Palaspata after the native name for the area. The temple complex is approximately 125 meters long by 145 meters wide — about the size of a city block — and includes 15 quadrangular enclosures arranged around a rectangular inner courtyard. This is a digital reconstruction of the temple.

A new model upends the decades-old “hard steps” theory that intelligent life was an incredibly improbable event and suggests that maybe it wasn't all that hard or improbable. The team of researchers said the new interpretation of humanity’s origin increases the probability of intelligent life elsewhere in the universe.

Mutations in the presenilin gene, PSEN1, causes early onset of Alzheimer’s disease in humans and in fruit flies modified to have this gene. A new study led by researchers at Penn State revels that disrupting heparan sulfate–modified proteins in fruit flies suppressed neuronal death and corrected other cell deficits common in early stages of Alzheimer’s and other neurodegenerative diseases. Pictured here are full fruit fly brains, stained with a marker that indicates cell death—brighter colors indicate higher presence of cell death. Top: A fly with deficits in the presenilin gene—a model for Alzheimer’s disease—with high levels of cell death. Bottom: A fly rescued by disrupting heparan sulfate–modified proteins.
