Methane in Saturn’s Moon’s Enceladus Feather: Possible Signs of Life?

This artist’s impression shows NASA’s Cassini spacecraft flying through a cloud of supposed water erupting from the surface of Saturn’s moon Enceladus. Credit: NASA An unknown methane-producing process is likely at work in the hidden ocean under the icy shell of Saturn’s moon Enceladus, a new study published in Natural astronomy by researchers at the University of Arizona and Paris …

Luca Parmitano: The astronaut who almost drowned in space

Of all the ways you can think of dying in space – designing aliens, robot losing its mind and trying to kill you, potato chips flying into the console, etc. – drowning is probably furthest away from any astronaut’s mind. Yet in July 2013, astronaut Luca Parmitano faced this very scenario while completing a spacewalk outside the International Space Station …

20,000 satellites falling to Earth could be worse than nuclear war

In most of these writings, satellites that go offline and then the ensuing chaos on Earth are all that happens. But what if these pieces of man-made hardware did not stay in orbit but went back to Earth for some reason? It’s a hypothetical situation that the boys are considering in What If for their latest doomsday scenario: 20,000 satellites …

New nanotechnology enables a ‘healthy’ production of electric current inside the human body

Credit: CC0 Public Domain A new nanotechnology development by an international research team led by researchers from Tel Aviv University will make it possible to generate electrical currents and voltage in the human body through activation of various organs (mechanical force). The researchers explain that the development involves a new and very strong biological material similar to collagen, which is …

Potentially more underground lakes found on Mars

One of the most difficult things to reconcile in science is when new data either complicates or refutes previous findings. It is even more difficult when these findings were widely publicized and heralded around society. But that’s how science works – the theories have to fit the data. So when a team from JPL analyzed data from Mars Express about …

Elon Musk says new spacecraft will “chomp up” Space Junk

“We can fly Starship around space and penetrate dirt with the movable cloak door.” Chomp L.‘eye The Earth’s orbit is becoming increasingly filled with our remaining waste. More than 27,000 pieces of orbital remains of various sizes are tracked by the Ministry of Defence’s global space surveillance network. It can make firing rockets increasingly difficult in the future, let alone …

Researchers unlock secrets behind liver regrowth and regenerative medicine

Credit: CC0 Public Domain NYU Abu Dhabi (NYUAD) researchers have uncovered a code that sets the liver’s genome to take into account the remarkable ability of this body to regenerate. This finding provides new insights into how the specific genes that promote regeneration can be activated when part of the liver is removed. These findings have the potential to inform …

Ultra-thin semiconductors are electrically connected to superconductors for the first time

The monolayer of molybdenum disulfide (MoS2) is sandwiched between two protective layers of boron nitride (hBN), with molybdenum rhenium (MoRe) contacts extending through the top. A layer of graphene (gate) is used for electrical control. Credit: Mehdi Ramezani, Swiss Nanoscience Institute, University of Basel Whether it is smartphones, television or building technology, semiconductors play a central role in electronics and …
