WASHINGTON – The Department of Transportation’s Federal Aviation Administration recently proposed a framework of regulations that would allow routine use of certain small unmanned aircraft systems (UAS) in today’s aviation system, while maintaining flexibility to accommodate future technological innovations.
The FAA proposal offers safety rules for small UAS (under 55 pounds) conducting non-recreational operations. The rule would limit flights to daylight and visual-line-of-sight operations. It also addresses height restrictions, operator certification, optional use of a visual observer, aircraft registration and marking, and operational limits.
The proposed rule also includes extensive discussion of the possibility of an additional, more flexible framework for “micro” UAS under 4.4 pounds. The FAA is asking the public to comment on this possible classification to determine whether it should include this option as part of a final rule. The FAA is also asking for comment about how the agency can —> Read More Here
On Feb. 25, International Space Station Commander Barry Wilmore and Flight Engineer Terry Virts of NASA continued rigging power and data cables during the second in a series of three spacewalks to prepare for installation of two new docking ports for the future arrival of U.S. commercial crew spacecraft.
Three-dimensional printing has been used to make everything from pizza to prostheses, and now researchers are working on using the emerging technology to fabricate hearts, kidneys, and other vital human organs.
That would be very big news, as the number of people who desperately need an organ transplant far outstrips the number of donor organs available. On average, about 21 Americans die every day because a needed organ was unavailable.
What exactly is the promise of 3D printing organs and tissues, or “
For answers to these and other questions, HuffPost Science reached out to Dr. Anthony Atala (right), director of the Wake Forest Institute for Regenerative Medicine and a world-renowned expert in the field, to find out.
See below for a lightly edited version of the Q & A.
Can 3D printing end the shortage of organs?
3D printing is not magic. It is simply a way to scale up the current processes we use to engineer organs in the laboratory. Our team has successfully engineered bladders, cartilage, skin, urine tubes and vaginas that have been implanted in patients. Our goal is produce organ structures such as these with 3D printing to make the —> Read More Here
The practice of mindfulness dates back at least 2,500 years to early Buddhism, and since then, it’s played an important role in a number of spiritual traditions.
While the stillness and connecting with one’s inner self cultivated through mindfulness are certainly an important part of a spiritual practice, feelings of wonder and awe — the amazement we get when faced with incredible vastness — are also central to the spiritual experience. And according to new research, mindfulness may actually set the stage for awe.
Mindfulness is the key element of the spiritual experience in a number of different religions.
Awe is defined as a feeling of amazement of fascination and amazement invoked by an encounter with something larger than ourselves that is beyond our ordinary frameworks of understanding. Previous research has shown that spirituality, nature and art are the most common ways that we experience awe.
“You can’t digest [the object of awe] with your cognitive structures — it’s too big for you,” University of Groningen psychologist Dr. Brian Ostafin told the Huffington Post. “So there’s a need for accommodation, to change your mental structures to understand what that is. This is the key element of the spiritual —> Read More Here
CAPE CANAVERAL, Fla (Reuters) – Two U.S. astronauts left the International Space Station on Sunday for a seven-hour spacewalk to install communications and navigation aides for new commercial space taxis.
