Safety concerns continue to impact ride sharing services

Safety concerns for passengers and even drivers continue to be a major cause of concern for the ride sharing industry around the world.

Companies like Uber and Lyft have benefitted greatly with the exponential growth in the industry, which did not exist just a decade earlier.

A better hologram for fraud protection and wearable optics

Holograms are a ubiquitous part of our lives. They are in our wallets — protecting credit cards, cash and driver’s licenses from fraud — in grocery store scanners and biomedical devices.   

Even though holographic technology has been around for decades, researchers still struggle to make compact holograms more efficient, complex and secure.

Small blue galaxy could shed new light on Big Bang

A faint blue galaxy about 30 million light-years from Earth and located in the constellation Leo Minor could shed new light on conditions at the birth of the universe.

Astronomers at Indiana University recently found that a galaxy nicknamed Leoncino, or "little lion," contains the lowest level of heavy chemical elements, or "metals," ever observed in a gravitationally bound system of stars.

When dung beetles dance, they photograph the firmament

The discovery that dung beetles use the light of the Milky Way to navigate in the world has received much praise. Researchers at Lund University in Sweden have now taken a new step in understanding the existence of these unique beetles: when the beetles dance on top of a ball of dung, they simultaneously take a photograph -- a snapshot -- of how celestial bodies are positioned.

Then they know where they are going and roll off with their ball of dung in a straight line across the savannah.

Rapid eye movement sleep: Keystone of memory formation

For decades, scientists have fiercely debated whether rapid eye movement (REM) sleep -- the phase where dreams appear -- is directly involved in memory formation.

Now, a study published in Science by researchers at the Douglas Mental Health University Institute (McGill University) and the University of Bern provides evidence that REM sleep does, indeed, play this role -- at least in mice.

Found: Surviving evidence of Earth's formative years

New work from a team including Carnegie's Hanika Rizo and Richard Carlson, as well as Richard Walker from the University of Maryland, has found material in rock formations that dates back to shortly after Earth formed. The discovery will help scientists understand the processes that shaped our planet's formative period and its internal dynamics over the last 4.5 billion years. It is published by Science.
