NASA spots perfectly rectangular icebergs in Antarctica
Geometric or tabular icebergs are a thing, and they're kinda beautiful.
- Rectangular icebergs have been spotted just off the Larsen Ice Shelf in Antarctica.
- They're called tabular icebergs, and are totally natural, though they don't look like it.
- The "alien" idea is tantalizing, but simply not real.
These oddly perfect slabs are known as tabular icebergs, and they're actually not that uncommon. They form when the edges of ice shelves break apart, and compared with the usual icebergs that most people think of, these are young and not yet deformed by wind and weather. While some have referred to them as "alien" creations, they're not.
"So, here's the deal," Kelly Brunt, ice scientist with the University of Maryland and NASA, told Live Science. "We get two types of icebergs: We get the type that everyone can envision in their head that sank the Titanic, and they look like prisms or triangles at the surface and you know they have a crazy subsurface. And then you have what are called 'tabular icebergs.'"

The photo above was taken by NASA scientist Jeremy Harbeck during an October 16 research flight over the Northern Antarctica Peninsula.
One of them in the video below is 100 miles long by 30 miles wide.
And all of the images and the ones in the video below are found off the Larsen Ice Shelf, Antarctica.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
- The word "creative" is sometimes waved around like a badge of honor. We speak of creativity in hushed tones, as the special province of the "talented". In reality, the creative process is messy, open, and vulnerable.
- For this reason, creativity is often at its best in a group setting like brainstorming. But in order to work, the group creative process needs to be led by someone who understands it.
- This sense of deep trust—that no idea is too silly, that every creative impulse is worth voicing and considering—is essential to producing great work.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
Normally, the landscape in this photo would be a white ice sheet.
- Climate scientists say that Greenland is experiencing ice losses that are unusually early and heavy.
- Two main weather factors are fueling the losses: a high-pressure system and the resulting low cloud cover.
- Greenland is a major contributor to sea-level rise.
