Extreme Magnetic Fields and Temperature Variation of Distant Magnetars
Posted by Quinn Sena in categories: cosmology, physics
New research is helping to explain one of the big questions that has perplexed astrophysicists for the past 30 years — what causes the changing brightness of distant stars called magnetars.
Magnetars were formed from stellar explosions or supernova e and they have extremely strong magnetic field s, estimated to be around 100 million, million times greater than the magnetic field found on earth.
The magnetic field on each magnetar generates intense heat and x-rays. It is so strong it affects the physical properties of matter, most notably the way that heat is co nducted through the crust of the star and across its surface, creating the variations in brightness which has puzzled astrophysicists and astronomers.

Revolutionary Self-Aware Materials Build the Foundation for Living Structures
Posted by Dan Kummer in categories: biotech/medical, nanotechnology
New research in Nano Energy introduces revolutionary scalable material that senses and powers itself.
From the biggest bridges to the smallest medical implants, sensors are everywhere, and for good reason: The ability to sense and monitor changes before they become problems can be both cost-saving and life-saving.
To better address these potential threats, the Intelligent Structural Monitoring and Response Testing (iSMaRT) Lab at the University of Pittsburgh Swanson School of Engineering has designed a new class of materials that are both sensing mediums and nanogenerators, and are poised to revolutionize the multifunctional material technology big and small.

NASA picks Venus as hot spot for two new robotic missions
Posted by Genevieve Klien in categories: robotics/AI, space
NASA is returning to sizzling Venus, our closest yet perhaps most overlooked neighbour, after decades of exploring other worlds.
The US space agency’s new administrator, Bill Nelson, announced two new robotic missions to the solar system’s hottest planet, during his first major address to employees.
“These two sister missions both aim to understand how Venus became an inferno-like world capable of melting lead at the surface,” Nelson said.

Venusian Acid-Cooked Turkeys, or Why I Still Read Blog Comments…
Posted by Randy Campbell in category: futurism
A bit early, (or a lot late 🙂) but I love this post. Beverage warnings apply:
In a world where many blogs and websites are shutting down comment threads, I think we all need the occasional reminder of why we permit comments. Sure, you often learn something new from other people’s inputs, and sometimes get corrected when you step beyond the limits of your actual knowledge-base too far. But sometimes you read a comment that’s so brilliant, you just have to look up the commenter’s email, and beg them for permission to repost their work of art. This was one of those times.

Motion of water monomers reveals a kinetic barrier to ice nucleation on graphene
Posted by Saúl Morales Rodriguéz in category: materials
The dynamics of water molecules at interfaces controls natural and artificial processes, but experimental investigations have been challenging. Here the authors investigate water molecules on a graphene surface using helium spin-echo spectroscopy, and reveal a regime where freely mobile molecules undergo strong repulsive mutual interactions which inhibit ice nucleation.
