Mars Does Have a Magnetic Field of Sorts – And We’ve Finally Got Data to Map It

Posted by in category: space

Unlike Earth, Mars doesn’t have a global magnetic field to protect it from the rigours of space weather – but it does have spots of local, induced magnetism.

Now, researchers have been able to create an incredible, detailed map of the electric currents that are responsible for shaping these magnetic fields.

It gives scientists a much greater understanding of how Mars might have lost much of its atmosphere over the course of billions of years, as well as how interactions between the solar winds and Mars’ magnetosphere are playing out today.

We Have Found Our Way To A Civil War

Posted by in category: futurism

Sadly, we have found our way to this place.


I am ashamed of our Political & Social Leaders. What we have allowed over the past few days is a group of #AntifaThugs and #AgentProvocateurs to run amuck in our fine country. We have allowed this scum to burn and rob and murder all for the fake belief of Social Justice.

George Floyd was murdered in the streets. He was murdered by a bad cop who is going to face justice for his actions, for good or for ill. The other officers who were on the scene who have not been arrested most likely will be. If they are not, then they are going to live with the fact that they watched a man die, who they should have protected.

SpaceX’s pioneering astronauts board the International Space Station

Posted by in categories: business, Elon Musk, space travel

Following a dramatic launch, 19-hour voyage and successful docking procedure, pioneering astronauts Robert Behnken and Douglas Hurley have left the Crew Dragon and are now aboard the International Space Station (ISS). The pair emerged from the Crew Dragon capsule at around 1:15 PM ET and were greeted with bear hugs by astronaut Christopher Cassidy and cosmonauts Anatoli Ivanshin and Ivan Vagner. While describing the ride as less smooth than the space shuttle, Hurley said he “couldn’t be happier” about the Crew Dragon’s performance.

The astronauts, who christened the Crew Dragon “Endeavor,” chatted with NASA executives after their arrival. “It’s great to get the United States back in the crewed launch business,” said Hurley. “And we’re just really glad to be onboard this magnificent complex.” Earlier, SpaceX founder Elon Musk said he was “quite overcome with emotion,” adding “this is hopefully the first step on a journey towards civilization on Mars.”

Predictive biology: modelling, understanding and harnessing microbial complexity

Posted by in categories: biological, engineering, physics

Predictive biology is the next great chapter in synthetic and systems biology, particularly for microorganisms. Tasks that once seemed infeasible are increasingly being realized such as designing and implementing intricate synthetic gene circuits that perform complex sensing and actuation functions, and assembling multi-species bacterial communities with specific, predefined compositions. These achievements have been made possible by the integration of diverse expertise across biology, physics and engineering, resulting in an emerging, quantitative understanding of biological design. As ever-expanding multi-omic data sets become available, their potential utility in transforming theory into practice remains firmly rooted in the underlying quantitative principles that govern biological systems. In this Review, we discuss key areas of predictive biology that are of growing interest to microbiology, the challenges associated with the innate complexity of microorganisms and the value of quantitative methods in making microbiology more predictable.

Iron Nanorobots Go Undercover to Track Living Cells Inside the Body

Posted by in categories: biotech/medical, nanotechnology

Customizable magnetic iron nanowires pinpoint and track the movements of target cells.

Living cells inside the body could be placed under surveillance—their location and migration noninvasively tracked in real time over many days—using a new method developed by researchers at KAUST.

The technique uses magnetic core-shell iron nanowires as nontoxic contrast agents, which can be implanted into live cells, lighting up those cells’ location inside a living organism when scanned by magnetic resonance imaging (MRI). The technique could have applications ranging from studying and treating cancer to tracking live-cell medical treatments, such as stem cell therapies.
