Optical Magnetic Field Sensor can Detect Ultra-Small Magnetic Fields

Posted by in categories: particle physics, quantum physics

Small magnetic fields from the human body can usually only be picked up by very sensitive superconducting magnetic field sensors that have to be cooled by liquid helium to near absolute zero (which is minus 273 degrees Celsius). But now researchers from the Niels Bohr Institute at the University of Copenhagen have developed a much cheaper and more practical optical magnetic field sensor that even works at room temperature or at body temperature.

“The optical magnetic field sensor is based on a gas of caesium atoms in a small glass container. Each caesium atom is equivalent to a small bar magnet, which is affected by external magnetic fields. The atoms and thus the magnetic field are picked up using laser light. The method is based on quantum optics and atomic physics and can be used to measure extremely small magnetic fields,” explains Kasper Jensen, assistant professor in the Center for Quantum Optics, Quantop at the Niels Bohr Institute at the University of Copenhagen.

Is invisibility cloak on its way to reality?

Posted by in categories: nanotechnology, particle physics

Invisibility cloak has hidden Harry Potter and hobbits from view and now, this sci-fi staple may be moving closer to reality!

Scientists at Queen Mary University of London (QMUL) have made an object disappear by using a composite material with nano-size particles that can enhance specific properties on the object’s surface.

Researchers demonstrated for the first time a practical cloaking device that allows curved surfaces to appear flat to electromagnetic waves.

This Tablet-Toting Military Vest Is Actually a Giant Battery

Posted by in categories: energy, military, mobile phones

Smartphones and tablets are being used more frequently in the battlefield, and that means that battery power is more important than ever. Soldiers often carry spare battery chargers in the 90-pound combat packs they carry into war zones, but the batteries are often lost or broken. BAE Systems wants to help lighten the load with its new system that lets soldiers plug electronics directly into their clothing.

The BAE Systems Broadsword Spine is a harness that can be sewn into a soldiers vest, jacket, or belt that carries a battery pack and hides charging wires. The harness places the battery pack on the small of a soldier’s back and includes eight conductive fabric conduits that can be used to connect to a USB port.

Silicon Valley Entrepreneurs Aim To ‘Hack’ the Brain

Posted by in categories: bioengineering, chemistry, cybercrime/malcode, neuroscience

Woo and other entrepreneurs are using fasts and other tricks to “hack” their brain chemistry like they would a computer, hoping to give themselves an edge as they strive to dream up the next billion-dollar idea. Known by insiders as “biohacking,” the push for cognitive self-improvement is gaining momentum in the Silicon Valley tech world, where workers face constant pressure to innovate and produce at the highest levels.

Scientists Invent Particles That Will Let You Live Without Breathing

Posted by in categories: biotech/medical, neuroscience, particle physics

Scientists invent particles that will provide oxygen to your body without breathing!!!


This may seem like something out of a science fiction movie: researchers have designed microparticles that can be injected directly into the bloodstream to quickly oxygenate your body, even if you can’t breathe anymore. It’s one of the best medical breakthroughs in recent years, and one that could save millions of lives every year.

The invention, developed by a team at Boston Children’s Hospital, will allow medical teams to keep patients alive and well for 15 to 30 minutes despite major respiratory failure. This is enough time for doctors and emergency personnel to act without risking a heart attack or permanent brain injuries in the patient.

Virtuix Omni Provides Virtual Worlds in Which to Walk, Run, and Jump

Posted by in categories: entertainment, health, virtual reality

2016 has been called the year that virtual reality becomes a reality, as some of the most anticipated devices will be made available on the consumer market. From Magic Leap (valued at over $1 billion) to Oculus (acquired by Facebook last year for $2 billion), there’s plenty of interest in the market, and ample room for it.

Though virtual reality is often depicted as an experience for the recliner or gaming chair, a number of VR enthusiasts want us to rethink how we engage with the technology. Instead of sitting around, they’d like to get us moving and looking beyond the go-to medium of gaming. Developers of these new devices consider fields like military training and healthcare as valuable places for mobile virtual reality to be applied.

Leading this approach is a Kickstarter VR company called Virtuix, whose treadmill-like device Omni encourages users to get upright and active. The reason to develop such a device felt like a natural evolution to Virtuix’s former Product Manager, Colton Jacobs.

“If I am walking in the virtual world my avatar is actually walking…”, he says, “…then the body’s natural reaction is, I want to stand up, I want to be walking with this avatar as if I’m actually there.”
