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 […]

Vega Older Than Previously Thought, Could Harbor Life

vega-lyra-age-fast-spinning

Vega is situated in the constellation Lyra, 25 light-years away from Earth, and it is the fifth brightest star in the sky. In 1983, astronomers discovered dust orbiting Vega, suggesting that it had a solar system. Vega was thought to be only a couple of hundred million years old, probably too young for any planets […]

The global population of hammerhead sharks, a group of sharks in the family Sphyrnidae, has plummeted by 89% in the last 20 years, largely due to illegal poaching and accidental fishing. Scientists have come up with a way to reduce the bycatch of hammerhead sharks. The scientists published their findings in the journal Fisheries Research. […]

Body Language is a Better Indicator of Intense Emotions than Facial Expressions

body-language-facial-cues

Intense emotional experiences are more easily read in body language than in watching facial expressions. Facial clues in most studies rely on a set of stylized, recognizable expressions, which don’t reflect the expressions that people make in the real world. The scientists published their findings in the journal Science. Hillel Aviezer, a neuropsychologist at the […]

Study Strengthens Link Between Human Activities and Climate Change

Study Strengthens Link to Human Activities in Climate Change

Comparing 20 of the latest climate models against 33 years of satellite data has lead the scientists of a newly published study to believe, with a high degree of certainty, that human activities are linked to climate change. New research shows some of the clearest evidence yet of a discernible human influence on atmospheric temperature. […]
