New Crater On Moon Made By Crash Of NASA’s LADEE Spacecraft

ladee impact

NASA is getting an up-close look at one of the moon’s newest craters, but this beauty mark wasn’t caused by a space rock that got just a little too close. It was created by the impact of a spacecraft that NASA deliberately smashed into the moon at 3,800 miles per hour.

The Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft, which studied the moon’s atmosphere, crashed into the surface of the far side on the completion of its seven-month mission in April. The 10-foot-diameter impact crater was found just two-tenths of a mile from its predicted location using images from the Lunar Reconnaissance Orbiter (LRO).

“The Lunar Reconnaissance Orbiter Camera (LROC) team recently developed a new computer tool to search Narrow Angle Camera (NAC) before and after image pairs for new craters, the LADEE impact event provided a fun test,” Mark Robinson, LROC principal investigator from Arizona State University in Tempe said in a news release. “As it turns there were several small surface changes found in the predicted area of the impact, the biggest and most distinctive was within 968 feet (295 meters) of the spot estimated by the LADEE operations team. —> Read More Here

Harnessing error-prone chips

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. In many popular applications — video rendering, for instance — users probably wouldn’t notice the difference, and it could significantly improve energy efficiency. —> Read More Here

Fetal alcohol spectrum disorders prevalence in U.S. revealed by study

Nearly 5 percent of U.S. children may be affected by fetal alcohol spectrum disorders (FASD), according to a new study. FASD are a group of conditions that can occur in the children of mothers who drank alcohol during pregnancy. Characteristics are both physical and cognitive and can include abnormal facial features, smaller-than-average physical growth, poor coordination, learning disabilities and vision and hearing problems. —> Read More Here

Heart’s own immune cells can help it heal

The heart holds its own pool of immune cells capable of helping it heal after injury, according to new research. In a mouse model of heart failure, the researchers showed that blocking the bone marrow’s macrophages from entering the heart protects the organ’s beneficial pool of macrophages, allowing them to remain in the heart, where they promote regeneration and recovery. The findings may have implications for treating heart failure in humans. —> Read More Here

Lord of the microrings

Researchers report a significant breakthrough in laser technology with the development of a unique microring laser cavity that can produce single-mode lasing on demand. This advance holds ramifications for a wide range of optoelectronic applications including metrology and interferometry, data storage and communications, and high-resolution spectroscopy. —> Read More Here
