What makes a bestseller: Fiction, thriller and a Christmas release

Books that are fiction, thrillers or mysteries, have high initial sales numbers and are released around Christmas are more likely to be bestsellers, according to a study published in the open access journal EPJ Data Science.

Frostburg State Students to Speak with NASA Astronaut in Space

King penguin breeding colonies are structured like fluids

Colonies of breeding king penguins behave much like particles in liquids do, according to a new study by the Woods Hole Oceanographic Institution (WHOI) and international colleagues. This "liquid" organization and structure enables breeding colonies to protect themselves against predators while also keeping members together.

How do very small particles behave at very high temperatures?

A nanomaterials expert has been looking at how small gold particles survive when subjected to very high temperatures.

Study suggests the elusive neutrino could make up a significant part of dark matter

Physicists trying to understand the fundamental structure of nature rely on consistent theoretical frameworks that can explain what we see and simultaneously make predictions that we can test. On the smallest scale of elementary particles, the standard model of particle physics provides the basis of our understanding.

Students to Compete in NASA's Human Exploration Rover Challenge; Media Invited

Media are invited to the U.S. Space & Rocket Center in Huntsville, Alabama, Friday, April 13, and Saturday, April 14, for NASA's Human Exploration Rover Challenge.

Why noise can enhance sensitivity to weak signals

A team of Japanese researchers has discovered a new mechanism to explain stochastic resonance, in which sensitivity to weak signals is enhanced by noise. The finding is expected to help electronic devices become smaller and more energy-efficient.

Oldest magnetic record in the solar system discovered in a meteorite

Researchers have found that an iron-containing mineral called dusty olivine, present in meteorites, retains a record of the magnetic field from the early solar system around 4.6 billion years ago. The results are surprising, as the magnetism in dusty olivine is non-uniform, and non-uniform magnetic materials have previously been thought to be poor magnetic recorders. The discovery may lead to new insight into how the solar system formed—with the help of magnetic fields—from a protoplanetary disk.

Computer simulation of boiling phenomena, bubble formation and two-phase bubbly flow inside nuclear reactors

The intrinsic beauty of bubbles—those thin watery spheres filled with air or other gases—has long captured the imagination of children and adults alike. But bubbles are also a linchpin of nuclear engineering, helping to explain the natural world, predict safety issues and improve the operation of the existing and next-generation nuclear fleets.
