Nyasasaurus, Oldest Dinosaur Believed to Be 243 Million Years Old

Nyasasaurus

Paleontologists think that they may have identified the earliest known dinosaur, which was no bigger than a Labrador retriever and lived 243 million years ago, during the Triassic Period. This is 10 million years earlier than the previously oldest known dinosaurs, and could change researchers’ views of how they evolved. The scientists published their findings […]

Satellites Could Be Used to Detect Nuclear Tests

nuclear-test-deterrent-gps-satellites

Underground nuclear tests can be detected in the skies and as a result, global satellite networks could become a powerful tool in order to detect clandestine underground nuclear explosions (UNE). The scientists presented their findings at the American Geophysical Union conference. The International Monitoring System (IMS) was established by the Comprehensive Nuclear-Test-Ban Treaty and has […]

Yale Engineers Develop Micro Fuel Cells Made of Bulk Metallic Glasses

micro fuel cell made of glass

Made up of mostly bulk metallic glasses, a new type of micro fuel cell could serve as a low-cost, long-lasting, and eco-friendly power source for portable electronic devices. Engineers at Yale University have developed a new breed of micro fuel cell that could serve as a long-lasting, low-cost, and eco-friendly power source for portable electronic […]

One of the strangest moons in the Solar System is Saturn’s Iapetus, which features an enormous equatorial mountain ridge and spiky belt that rises 12 miles above the moon’s surface may have all been the result of a single impact. The findings were presented at the American Geophysical Union conference on December 4. Scientists suggest […]

Cocoons form to protect eggs and larvae, but they can also help preserve fossils for hundreds of millions of years. This 25-micrometer-long protozoan was trapped in the wall of an egg case produced by a leech between 200 million and 215 million years ago, during the Triassic Period. The scientists published their findings in the […]

Herschel and Keck Reveal Previously Unseen Starburst Galaxies

previously unseen starburst galaxies revealed

Using ESA’s infrared Herschel space observatory and spectrometers on the twin 10-metre W.M. Keck telescopes on Mauna Kea, Hawaii, astronomers characterized 767 previously unseen starburst galaxies, revealing extraordinary high star-formation rates across the history of the Universe. Starburst galaxies give birth to hundreds of solar masses’ worth of stars each year in short-lived but intense […]

5-Mile Wide Buried Asteroid Crater Discovered in Canada

bow-city-crater-canada

A 5-mile wide and 3,000 foot deep asteroid impact crater has been hidden near Bow City, Alberta, for millions of years. Bow City has been deserted for decades. The findings were presented at the American Geophysical Union conference on December 3rd. People have suspected something odd in the region since the 1930s, because of the […]

Humans are a Greater Disturbance to Elk than Natural Predators

vigilant-elk

A new study has shown that elk become more fearful when people are around because they perceive humans as predators. The scientists published their findings in the journal PLOS ONE. The researchers studied elk (Cervus canadensis) in Alberta, Canada. The results come from a year-long study that tracked 424 herds and 870 individuals on public, […]

Titan’s Icy Outer Crust is Likely Twice as Thick as Previously Believed

Titan's icy outer crust is likely twice as thick as previously thought

Using radar data from NASA’s Cassini spacecraft, a new analysis of Saturn’s largest moon, Titan, suggests that it has an icy, rocky core with a radius of a little over 2,000 kilometers, an ocean somewhere in the range of 225 to 300 kilometers thick and an ice layer that is 200 kilometers thick. A new […]

Inherent Complexity of the Wheat Genome

bread-wheat

An international team has produced a rough draft of wheat’s DNA sequence. The draft identifies many of its genes and makes it possible to identify thousands of potential genetic changes that could improve this crop. It’s been long considered one of the most important crop genomes. The scientists published their findings in the journal Nature. […]

“Coughing” Scallops Are Early Warning System for Worsening Water Quality

coughing-scallops-science

Scallops cough to expel feces and water from their central cavities. The friction between the mollusk’s two valves makes a sharp crack, followed by a drawn-out puffing sound as the valves close. Biologists think that these coughs could serve as an early warning system for worsening water quality. The scientists published their findings in the […]

Voyager 1 Enters “Magnetic Highway,” The Final Area before Interstellar Space

Voyager 1 Encounters New Region in Deep Space

NASA’s Voyager 1 spacecraft entered a magnetic highway for charged particles, the final region before it reaches interstellar space. Pasadena, California — NASA’s Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space. […]

Drunken Larvae Learn Just as Well as Sober Larvae

drunk-fruit-flies-larvae

Many studies suggest that the behavioral effects of alcohol in humans can be modeled in fruit flies and other animals. Scientists that were trying to see when these effects start to take place discovered that inebriated fruit fly larvae learned just as well as sober ones. The scientists published their findings in the journal Current […]
