New massive duck-billed dinosaur species identified

There's a new dinosaur species on the block. An international team, including a biologist from Penn State Lehigh Valley, discovered that a 75-million-year-old fossil classified as a different dinosaur is its own massive, duck-billed species. Working with the New Mexico Museum

Ultrasonic pest control can protect beehives

Bees, and other pollinator species, are dying. Between pesticides, the climate crisis, and habitat loss, bee colonies are becoming weaker, leaving them more vulnerable to parasites like the greater and lesser wax moths. Vulnerable bees have cascading effects on beekeepers and

A new role for DNA loops in repairing genetic damage

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its DNA structure to speed up the search for an intact copy of the damaged region.

Nanotyrannus was not a juvenile T. rex, new study confirms

For decades, paleontologists argued over the lone skull used to establish the distinct species Nanotyrannus. Was it truly a separate species or simply a juvenile Tyrannosaurus rex? A new paper published in Science has definitively shown that Nanotyrannus is, in fact, nearly

How sound moves on Mars

Acoustic signals have been important markers during NASA's Mars missions. Measurements of sound can provide information both about Mars itself—such as turbulence in its atmosphere, changes in its temperature, and its surface conditions—and about the movement of the Mars rovers.
