Water Detected In Rocks From Below The Moon’s Surface – The Daily Orbit
Mapping water on the moon.
Ladies are you really anxious about math?
DARPA’s doing what now?
And a mind over mind on the Daily Orbit!
Hello and welcome to the Daily Orbit. I’m Emerald Robinson.
Here’s more evidence for water on the moon. A NASA-funded project using data from the space agency’s Moon Mineralogy Mapper aboard an Indian spacecraft has detected magmatic water—water that originates deep within the lunar interior. Researchers looked to an impact crater for clues. Rocks that are usually found deep within the moon were brought to the surface of the central part of the crater during impact. These particular rocks contain “a significant amount of hydroxyl—a molecule consisting of one atom and one hydrogen atom—which is evidence that rocks in this crater contain water that originated beneath the lunar surface.” This discovery is important because it indicates that water was probably a part of the forming moon, and not deposited on the surface from comets.
So they used to say girls just weren’t as good at math. Then they said girls have math anxiety. But come on, how true is that really? A new study says that girls are not actually experiencing the math anxiety scientists thought they were. Where did studies past fail? They relied on self-reported anxiety rather than assessing stress levels during actual math exams. The new study found that, like research past, girls self-reported more anxiety about math than boys. But real-time assessments taken during math class found that girls did not experience more anxiety than boys in a real-life setting. Researchers believe that common stereotypes about girls and math lead them to report more anxiety and go even further to say that this could partly be the reason more women do not pursue careers in math-intensive fields. So girls, you can do math! Don’t be afraid and don’t let anyone tell you any different!
I always love to hear what DARPA’s up to and today’s news does not disappoint. DARPA is looking to create a special suit for the military called Warrior Web that would prevent injury and boost endurance. With a look of something that would be produced in Stark Laboratories, the suit would prevent some of the most common injuries for soldiers on the battlefield—those that come from carrying 100 pounds of gear. The Warrior Web will be lightweight, soft and allow soldiers to perform more efficiently while protecting injury-prone areas. It’s like a protective exoskeleton. DARPA already has several different pieces in the works but is looking at how these could be combined to create the web. They are also taking ideas from developers. Got an idea? You have until October 3 at 4:00 p.m. EST to get it in. Two things I love about this idea: 1. The name…how cool is that! 2. That it’s meant to help better protect our guys out there in the field.
And the agency is also “gearing” up for their next challenge. DARPA is readying for their Robotics Challenge in December where they will have teams competing to give a humanoid robot human-like dexterity and mobility that could be used during rescue missions and disasters. DARPA is teaming up with the Southwest Research Institute to develop and support a test apparatus for robotics evaluation in the challenge. The apparatus will assess the dexterity and mobility of each team’s robot. Scoring will be based on performance in areas such as driving a four-wheel drive vehicle, traversing uneven terrain on foot, and cutting holes in walls. I can’t wait for the games to begin!
And DARPA may be interested in controlling the mind of a robot but other researchers are more interested in controlling the human mind. A researcher at the University of Washington was reportedly able to transmit a brain signal through the Internet and control the hand motions of a colleague. It’s being heralded as the first noninvasive person-to-person interface. During the experiment the researcher applied a type of magnetic stimulation to his colleague’s left motor cortex—the area of the brain responsible for controlling hand movement—to get his hands to move on a keyboard. The researcher would imagine pressing the “fire button” for a video game but would not actually move his hand, while at the same time the colleague would involuntarily move his right index finger as if firing. The researcher referred to it as the “Vulcan mind meld.”
And that’s it for the Daily Orbit.
