Singer sues Disney, Demi Lovato, Idina Menzel claiming 'Let it Go' ripped his song off

  Singer sues Disney, Demi Lovato, Idina Menzel claiming 'Let it Go' ripped his song off A Chilean singer is suing anyone remotely connected to the smash hit “Let it Go,” claiming it was shamelessly ripped off from one of his songs. Jaime Ciero claims in a new lawsuit that the smash hit from "Frozen" was inspired by his 2008 song “Volar” and wants royalties from Disney, Idina Menzel and Demi Lovato.According to TMZ, Ciero said his single was “a huge international success reaching millions of listeners and landing on numerous charts of the most popular, top-performing songs.

Neukum) One of the deepest craters in Mars' Tagus Valles region lies in the foreground of this perspective view. Numerous landslides have occurred within this crater, leaving grooves in the wall as material slumped to the floor below. Powerful landslides may rumble down Martian slopes at up to 450 mph (725 km/h), sped along by slippery ice, a new study suggests.

Researchers Fabio Vittorio De Blasio and Giovanni Battista Crosta, both of the University of Milano-Bicocca in Italy, modeled the dynamics of landslides on Mars, especially those inside Valles Marineris, the gigantic canyon system near the Red Planet's equator.

NASA goes back to the middle ages for its rover tire design

  NASA goes back to the middle ages for its rover tire design The Mars Curiosity rover has been a big success, but NASA's modern tech couldn't save its tires from breaking down in the harsh conditions of Mars. Curiosity's wheels have taken a lot of damage because they don't have much give, and Mars rocks can be particularly jagged. NASA's new chainmail type material, on the other hand, provides a lot more flexibility, while still being difficult to penetrate, as shown in the video below. In another configuration, the material could also be useful to NASA as an all-purpose, lightweight heat and debris shield for orbiting spacecraft.

Powerful landslides may rumble down Martian slopes at up to 450 mph (725 km/h), sped along by slippery ice, a new study suggests. Mega Landslides on Mars can glide down the Martian slopes at a maximum speed of 725 km / h.

The duo found that ice — at the landslides' bases and/or spread widely throughout the Martian soil — is likely a key player in these dramatic flows of Red Planet rock and dirt.

"Only if the presence of ice is included in the calculations do results reproduce reasonably well both the vertical collapse of landslide material in the scarp area, and the extreme thinning and runout in the distal area, which are evident characteristics of large landslides in Valles Marineris," they wrote in the new study, which was published this month in The European Physical Journal Plus.

This conclusion fits with other available evidence, the researchers added. For example, Valles Marineris landslides look a lot like landslides here on Earth that fall onto glaciers, they wrote.

And then there's the Martian landslides' speed.

"The calculated velocity of landslides (often well in excess of 100 m/s and up to 200 m/s at peak) compares well with velocity estimates based on the run-up of the landslides on mounds," the researchers wrote. "We conclude that ice may have been an important medium of lubrication of landslides on Mars, even in equatorial areas like Valles Marineris."

One hundred meters per second is about 225 mph (362 km/h), and 200 meters per second is roughly 450 mph (725 km/h). To put that into perspective, the superfast "pyroclastic flows" that barrel down volcanic slopes during eruptions here on Earth top out at about 150 mph (240 km/h), according to the U.S. Geological Survey. And most terrestrial landslides are much slower than that.

New island offers clues in search for life on Mars: NASA .
The world's newest island -- formed during a volcanic eruption in the remote Pacific three years ago -- may offer clues to how life potentially developed on Mars, NASA said Wednesday. The island of Hunga Tonga Hunga Ha'apai rose from the seabed about 65 kilometres (40 miles) northwest of the Tongan capital Nuku'alofa in late 2014-early 2015.Scientists initially expected the island -- created when vast quantities of rock and dense ash spewed from the Earth's crust -- to wash away within a few months.
