Scientists at Macquarie University have developed a laser similar to the sci-fi superlaser used by the Death Star in Star Wars. A superlaser combines the multiple laser beams into a single beam.
"Researchers are developing high power lasers to combat threats to security from the increased proliferation of low-cost drones and missile technology," Rich Mildren, an associate professor of physics...
Solar wind and radiation are responsible for stripping the Martian atmosphere, transforming Mars from a planet that could have supported life billions of years ago into a frigid desert world, according to new results from NASA's MAVEN (Mars Atmosphere and Volatile Evolution Mission) spacecraft led by the University of Colorado Boulder.
"We've determined that most of the gas ever present in...
Scientists at Louisiana State University have identified a new tyrannosaur that directly evolved from its geologically older ancestor through anagenesis.
The international team of scientists discovered the new tyrannosaur Daspletosaurus horneri or Horner's Frightful Lizard that evolved directly from its older relative, D. torosus.
This rare form of evolution is known as anagenesis and...
Albert Einstein is undoubtedly not just one of the most well-known scientists ever but one of the most well-known figures in history, period. But while his contributions to modern society are famous, was he really such a great guy? The FBI, for one, wasn't so sure.
Einstein was born in Germany in the year 1879, but that's not the country that wanted him so desperately. The famous scientist was...
In order to image one of the world's largest viruses, the Samba virus, scientists at Michigan State had to design and build their own microscope.
Researchers retrofitted a transmission electron microscope with a cryostage, a device used to keep biological samples frozen in liquid nitrogen. Scientists used the cryo-electron microscope to map the Samba virus and observe it as the virus invaded...
In the wake of a recent electromagnetic storm, NASA's Van Allen Probes identified unique chemical reactions inside Earth's magnetic field. The findings offered new insights into how particles flow through near-Earth space.
The Van Allen radiation belts are a pair of giant rings populated by high energy charged particles trapped by Earth's magnetic field. The Van Allen Probes, NASA's twin...
Scientists at the National Center for Atmospheric Research have discovered Rossby waves on the sun. The large-scale planetary waves were first discovered on Earth.
On Earth, Rossby waves are correlated with local weather events. On the sun, scientists suggest the waves could influence solar activity and related phenomena, like sunspots and solar flares.
"The discovery of magnetized Rossby...
Scientists have discovered an unprecedented diversity of dinosaur tracks along a stretch of Australia's Dampier Peninsula coastline. Researchers dubbed the fossil-rich acreage "Australia's Jurassic Park."
Along the 15-mile stretch of coast called Walmadany, paleontologists identified 150 tracks belonging to 21 different dinosaur types.
Lead researcher Steve Salisbury called the coastline...
New research suggests land-based sources are tainting coral reefs with invasive bacteria and fungi. The foreign organisms could upset the microbial balance of an ecosystem already under threat from global warming.
Scientists measured the makeup of microbial communities in reefs off Florida's southeastern coast using a technique called "high throughput next generation DNA sequencing." Modeling...
The spiral galaxy NGC 1448 is located 50 million light-years from Earth. It can be appreciated more intimately thanks to a new closeup image captured by Hubble's Wide Field Camera 3.
Scientists shared the portrait of the frisbee-shaped galaxy on NASA's website this week.
Often, images of spiral galaxies reveal a cyclone-like disk. From another angle, NGC 1448 would offer a similar...
