High-fat diet might put your mental health at risk

high fat diet

Mice that had gut bacteria transferred from other mice fed with a high fat diet changed their behavior in a negative way, exhibiting anxiety or impaired memory. The findings suggest that apart from heart disease and stroke, obesity might put people’s mental health at risk as well.

NASA wants to take a piece of an asteroid and make it a moon of the Moon

It almost sounds too cheesy to be true: NASA wants to send a shuttle to an asteroid, pluck a piece of it, then make it return to the Moon and orbit it. Then, brave astronauts will go and retrieve the sample, bringing it back to Earth for study. But that’s exactly what astronomers and engineers at the space agency want to do.

Scientists discover another layer in the Earth’s mantle

earth mantle layer

Most people tend to think of the Earth in terms of crust, mantle and core, and while those are indeed the largest “layers” (you can’t properly call the mantle a layer though), each one of them is made from other, thinner layers. Now, researchers from the University of Utah have identified another one of these thinner layers, 930 miles beneath our feet.

Paleontologists have found the remains of a “super salamander” – a previously unknown car-sized species of early amphibian. The predatory salamander likely feasted on fish and even small dinosaurs.

Young Jupiter Swept Through the Solar System, Destroying Super Earths

A new shocking theory suggests that Jupiter may have sweeped through our solar system much like a wrecking ball, knocking planets out of the solar system our moving them outwards, to the position we see them in today. If this is true, then it might explain why our solar system is a rarity and why life emerged the way it did.

Exploding supernova ejects enough material to seed 7,000 Earths

Everything is made of stardust – but some things are made of more stardust than others. A new study has found that a single supernova is capable of producing large enough quantities of dust to create thousands of planets like Earth.

With spring starting to settle in, snow is likely the last thing on people’s minds – but NASA is taking snow really seriously. They want to put satellites in orbit to understand how the frozen lands in the polar areas are developing and adapting to climate change.

Minuscule Centaur planet in our Solar System might have rings like Saturn

chiron minor planet

They’re considered a hybrid between asteroids and comets, but still, they’re called minor planets; they also bear the name of the fabled man-horse creatures in Greek mythology – centaurs. Now, scientists have found that a Centaur in our solar system, Chiron, might have rings just like those of Saturn.

AstroPicture of the Day: An Eclipse at the End of the World

AntarcticEclipse_bruenjes_960

A total solar eclipse took place on November 23, 2003; the Moon elegantly set itself in between the Sun and the Earth, but this was only visible from the Antarctic region. But that didn’t stop an enthusiastic group of photographers who went on to take some stunning pictures, including the one you see above. The image, pictured as an APOD,

Some 480 million years ago the seven-foot-long Aegirocassis benmoulae swam in a shallow sea covering what is today the Sahara desert. This giant arthropod, much larger than arthropods existing today, was likely the biggest creature in the world at the time.
