It's old news that open-source 3D printing has a lot going for it: it's cheap, green and incredibly useful for making everything from lab equipment to chess pieces. Now it's time to add another star to the 3D printing constellation. It may help lift some of the world's most destitute people from poverty while cleaning up a major blight on the earth and its oceans: plastic trash.

At the center of the movement is a new set of standards inspired by fair trade products ranging from diamonds to chocolate.

Current changes in the ocean around Antarctica are disturbingly close to conditions 14,000 years ago that new research shows may have led to the rapid melting of Antarctic ice and an abrupt 3-4 metre rise in global sea level.

The research published in Nature Communications found that in the past, when ocean temperatures around Antarctica became more layered - with a warm layer of water below a cold surface layer - ice sheets and glaciers melted much faster than when the cool and warm layers mixed more easily.

Messier 11 is an open cluster, sometimes referred to as a galactic cluster, located around 6000 light-years away in the constellation of Scutum (The Shield). It was first discovered by German astronomer Gottfried Kirch in 1681 at the Berlin Observatory, appearing as nothing more than a fuzzy blob through the telescope. It wasn't until 1733 that the blob was first resolved into separate stars by the Reverend William Derham in England, and Charles Messier added it to his famous catalogue in 1764.

"But as the minutes ticked by, the relaxed attitude of many of us began to dissolve into apprehension. Our levels of adrenaline and worry began to rise."

"The room went silent, interspersed with only an occasional murmur, all faces fixed on a noisy, fuzzy line on our computer screens."

On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions was as much as 10,000 times more powerful than the largest solar flare ever recorded.

NASA and NOAA scientists participating in NASA's Hurricane and Severe Storms Sentinel (HS3) mission used their expert skills, combined with a bit of serendipity on Sept. 17, 2014, to guide the remotely piloted Global Hawk over the eye of Hurricane Edouard and release a sonde that rotated within the eye as it descended and fell into the eyewall of the storm at low levels.

Tropical Storm Rachel is spinning down west of Mexico's Baja California, and another tropical low pressure area developing off the coast of southwestern Mexico dwarfs the tropical storm. NOAA's GOES-West satellite showed the size difference between the two tropical low pressure areas.

The bands of thunderstorms wrapping around Tropical Storm Phanfone in the Northwestern Pacific Ocean appeared fragmented to NASA's TRMM satellite.

In a study published this week in the online journal PeerJ, University of Connecticut researchers announce they have found a way to prevent Monk Parakeets (Myiopsitta monarchus), an invasive species of parrot, from building huge nests that create power outages and public hazards on utility poles by blocking their access to the electric lines that are the gateway to their nest sites.

The nests, which are built out of sticks and twigs, can weigh up to 200 pounds or more. The damage they cause can cost electric utility companies millions of dollars annually.

CAMBRIDGE, Mass--The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that reach Earth's surface from the sun — but not much of the rest of the spectrum, since that would increase the energy that is reradiated by the material, and thus lost to the conversion process.

Thanks in part to support from NASA and the National Science Foundation, scientists have produced the first-ever detailed maps of bedrock beneath glaciers in Greenland and Antarctica. This new data will help researchers better project future changes to glaciers and ice sheets, and ultimately, sea level.

On Sept. 30, 2014, a sounding rocket will fly up into the sky – past Earth's atmosphere that obscures certain wavelengths of light from the sun -- for a 15-minute journey to study what heats up the sun's atmosphere. This is the fourth flight for the Very high Angular Resolution Ultraviolet Telescope, or VAULT, will launch from the White Sands Missile Range near Las Cruces, New Mexico.

WASHINGTON, DC – September 29, 2014 -- Plants have a symbiotic relationship with certain bacteria. These 'commensal' bacteria help the pants extract nutrients and defend against invaders – an important step in preventing pathogens from contaminating fruits and vegetables. Now, scientist have discovered that plants may package their commensal bacteria inside of seeds; thus ensuring that sprouting plants are colonized from the beginning. The researchers, from the University of Notre Dame, presented their findings today at the 5th ASM Conference on Beneficial Microbes.

NASA's Aqua satellite passed over newborn Tropical Storm Phanfone on Sept. 29 and captured a picture of the storm that showed thunderstorms wrapped tightly around the storm's center, and a large band of thunderstorms spiraling into the center from the east. Phanfone is now a threat to various islands and warnings are in effect.

A tropical storm Warning is in effect for Saipan, Tinian, Pagan and Alamagan. In addition, a typhoon watch is in effect for the northern Marianas Islands, including Pagan and Alamagan.

Tropical Storm Kammuri continues to appear more like a cold front on satellite imagery as it transitions into an extra-tropical storm over the Northwestern Pacific Ocean.

When NASA's Terra satellite passed over Kammuri on Sept. 29 at 7:40 a.m. EDT (11:40 UTC), the Moderate Resolution Imaging Spectroradiometer or MODIS instrument captured an infrared look at the storm. MODIS showed that the bulk of strong storms elongated from southwest to northeast.
