Mysterious Anti-electron Clouds Inside Thunderstorm

DURHAM — A terrifying few moments flying into the top of an active thunderstorm in a research aircraft has led to an unexpected discovery that could help explain the longstanding mystery of how lightning gets initiated inside a thunderstorm.

University of New Hampshire physicist Joseph Dwyer and lightning science colleagues from the University of California at Santa Cruz and Florida Tech describe the turbulent encounter and discovery in a paper to be published in the Journal of Plasma Physics.

In August 2009, Dwyer and colleagues were aboard a National Center for Atmospheric Research Gulfstream V when it inadvertently flew into the extremely violent thunderstorm—and, it turned out, through a large cloud of positrons, the antimatter opposite of electrons, that should not have been there.

To encounter a cloud of positrons without other associated physical phenomena such as energetic gamma-ray emissions was completely unexpected, thoroughly perplexing and contrary to currently understood physics.

Patents for technology to read people’s minds hugely increasing

Via The Independent:

Companies are taking out a huge amount of patents related to reading brainwaves, according to analysis, with a range of different applications.

Fewer than 400 neuro-technology related patents were filed between 2000-2009. But in 2010 alone that reached 800, and last year 1,600 were filed, according to research company SharpBrains.

The patents are for a range of uses, not just for the healthcare technology that might be expected. The company with the most patents is market research firm Nielsen, which has 100. Microsoft also has 89 related patents.

Other uses of the technology that have been patented include devices that can change the thoughts of feelings of those that they are used on.

GABRIEL MELLAN: A Retroreflective

GABRIEL MELLAN: A RETROREFLECTIVE

Reflective art in the dark made for the flash of a camera phone and a third-eye-LED.

Thursday May 7, 2015
6 – 9 pm
33 Washington st
Brooklyn NY 11201

Rabbithole Projects is proud to present
in conjunction with DUMBO First Thursday Gallery Walk

The experience:

Contrasting the traditional gallery viewing experience, the lights will be off, use the flash on your smartphone to photograph the work. A third LED eye will be provided for you to illuminate the art and navigate the space. This exhibition is kid friendly, assuming they are a bit adventurous and can handle a cameraphone. Selfies and flash photography are encouraged.

How it works:

The auto exposure and autofocus feature on smartphones work to make these pieces visible. The autofocus involves a short burst of light to help the camera focus in the dark. When the light to help focus the camera hits the retroreflective surfaces and is bounced back, the camera reads the environment to have more light than there is.

Nam’s Mission

137

Monday

4:15am:
I awake groggy from the weekend. And I want to call in sick. (ZzZzzzzzZZzzz.)

4:20am:
Ugh! I should work! (ZzzZZZzzz.)

4:25am:
Besides, the road might be a good distraction from my mental state. (ZZzzZZzzz.)

4:30am:
Okay! Okay! I’ll get up!

5:05am:
It’s a (now) rare foggy day in ‘ol San Francisco. I’m slogging up through the Citizen’s Cab lot and headed towards the office.

As I near, Sammy – the new office guy who’s taken over Kojak’s morning shift, passes me. He’s leaving the office with some new West African driver. They’re heading out to the lot … with a jump starter.

Note: Kojak has been moved to the afternoon office shift for some unknown reason. (Unknown to me, anyway.) This is how the cab biz works. Drivers, office workers; one day ya see ‘em. And the next, they’re gone.

Anyway, hmm.

DARPA’s Extreme Accuracy Tasked Ordnance (EXACTO) Magic Bullets

The boffins at DARPA have come up with a pretty cool idea – bullets that magically adjust course to hit their target. Here’s what they say about the video they’ve released:

DARPA’s Extreme Accuracy Tasked Ordnance (EXACTO) program, which developed a self-steering bullet to increase hit rates for difficult, long-distance shots, completed in February its most successful round of live-fire tests to date. An experienced shooter using the technology demonstration system repeatedly hit moving and evading targets. Additionally, a novice shooter using the system for the first time hit a moving target.

This video shows EXACTO rounds maneuvering in flight to hit targets that are moving and accelerating. EXACTO’s specially designed ammunition and real-time optical guidance system help track and direct projectiles to their targets by compensating for weather, wind, target movement and other factors that can impede successful hits.

Voice Profiling Software Dehumanizes Hiring Decisions

Dystopian science fiction is so prevalent in popular culture today that when voice profiling software is announced by a corporation it barely registers as a surprise to a new generation of job hunters. The Guardian reports on this dehumanizing trend in hiring:

Imagine that you’re a contestant in an audition round of The Voice, where you belt out your best “I Will Always Love You”. A minute passes. No reaction from the celebrity judges. You keep singing. Another minute, still no encouraging smile or nod. You strain to hit your highest note, pleading with your performance: “Please, please accept me! I am doing my best!” The song ends. No one wants you. Your family bow their heads in shame. Your mom cries. You stand on the stage, alone in the spotlight, heartbroken. A trap door opens beneath your feet and you slide screaming into Adam Levine’s basement torture maze.

It’s still possible we all live inside a hologram

Jamie Lendino via ExtremeTech:

Mathematicians are already familiar with the holographic principle, which the famous physicist Leonard Susskind first proposed. It asserts that a volume of space can be thought of as encoded on a boundary to it — such as an observer-dependent gravitational horizon — and therefore needs one less dimension then it appears to need. By extension, since our universe seems three-dimensional to us, it could actually be a two-dimensional structure that’s overlaid onto an incredibly large cosmic horizon.

Back in 1997, Juan Maldacena first postulated the theory of a holographic universe, saying that gravity arises from thin, vibrating strings that exist in 10 dimensions. Other physicists have been working with the concept since.

“The work culminated in the last decade, and it suggests, remarkably, that all we experience is nothing but a holographic projection of processes taking place on some distant surface that surrounds us,” wrote physicist Brian Greene, from Columbia University, in 2011.

Project Elysium: VR to revive deceased loved ones

A development screenshot from Project Elysium.

A development screenshot from Project Elysium. Paranormal Games.

Mark Walton via Ars Technica:

How far is too far when it comes to pushing the boundaries of virtual reality? As VR devices grow ever more sophisticated—and the tools to create software for them ever more accessible—where do we draw the line between what’s ethically acceptable in the real world and what’s ethically acceptable in the virtual world?

One of the developers putting this question to the test is Australia-based Paranormal Games. Project Elysium, its entry into the upcoming Oculus VR Jam 2015, treads some shaky moral ground by promising to create a “personalized afterlife experience,” reuniting people with loved ones who have passed on. Exactly how the developer hopes to do this isn’t clear at this point (it will be required to showcase screenshots by April 27, followed by video footage the week after to be eligible for the jam’s grand prize), although a screenshot from Project Elysium’s development does show a friend of the studio being transformed into a 3D model.
