Tragic death of a Chinese women using iPhone 5 while charging

A 23-years old woman, namely Ma Ailun, was electrocuted to death by iPhone 5 while attending the call during its charging last Thursday as reported by Chinese news outlet Xinhaunet.

According to the reports, Ma Ailun, bought iPhone in December last year and was charging the phone with the original charger. She was planning her wedding on August 8.

According to experts, mobile phones have a low voltage output of only 3 to 5 volts, which is not enough to harm the human body. Therefore, several other factors could also be involved in the electrocution.

"I want to warn everyone else not to make phone calls when your mobile phone is recharging," Ma's sister tweeted.

Apple is looking into the report. "We are deeply saddened to learn of this tragic incident and offer our condolences to the Ma family. We will fully investigate and cooperate with authorities in this matter," Apple's Beijing-based spokesperson Carolyn Wu said.

S/2004 N 1 - the smallest and newly discovered moon of Neptune

(This article has been cross-posted from SayPeople.com)

Main Point:

Astronomers discovered a tiny new moon, dubbed S/2004 N 1, around Neptune with the help of Hubble Space Telescope on July 1 and announced it on July 15.

Study Further:

Astronomers have reported that the new moon is the Neptune’s smallest moon of 14 of the known moons. It is just 12 miles (19 kilometers) wide. This moon is so small that it is about 100 million times fainter than the dimmest star.

"The moons and arcs [segments of rings around the planet] orbit very quickly, so we had to devise a way to follow their motion in order to bring out the details of the system," SETI Institute scientist Mark Showalter, the moon's discoverer, said in a statement. "It's the same reason a sports photographer tracks a running athlete — the athlete stays in focus, but the background blurs."

Scientists studied the photos taken by Hubble from the year 2004 to 2009 and found the moon in about 150 of those photos. They determined that the tiny moon orbits the Neptune about every 23 hours.

First image of Pluto’s largest moon by NASA’s New Horizons spacecraft

Main Point:

NASA’s Pluto-bound New Horizons spacecraft took the first image of Charon, i.e. largest moon of the Pluto, with the help of highest-resolution telescopic camera.

Study Further:

Charon, discovered in 1978, is the largest moon of the Pluto’s five known moons. It is almost the size of Texas State of U.S. and is covered by ice. Charon is orbiting about 12,000 miles (more than 19,000 kilometers) away from Pluto.

The spacecraft was 550 million miles (885 million km) from Pluto, when its LOng Range Reconnaissance Imager (LORRI) snapped a total of six images: three July 1 and three more July 3.

“The image itself might not look very impressive to the untrained eye, but compared to the discovery images of Charon from Earth, these ‘discovery’ images from New Horizons look great!” said New Horizons Project Scientist Hal Weaver of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. “We’re very excited to see Pluto and Charon as separate objects for the first time from New Horizons.”

“We’re excited to have our first pixel on Charon,” New Horizons Principal Investigator Alan Stern of the Southwest Research Institute said, “but two years from now, near closest approach, we’ll have almost a million pixels on Charon — and I expect we’ll be about a million times happier too!”

Electronic skin will help amputees to sense environment

(Cross-posted from Jeeget.blogspot.com)

Scientists from Technion-Israel Institute of Technology have developed a sort of electronic skin having flexible sensors operating on low voltage that would help amputees to sense touch, humidity and temperature.

This e-skin could be attached to prosthetic limbs and would help them to sense the environment. It is a major breakthrough as the current devices detect only touch.

In this research, scientists utilized gold particles and a kind of resin that is about 10 times more sensitive to touch than the traditional e-skin devices.

Over 60 billion habitable planets probably present in our Milky Way

Main Points:

Scientists have estimated that there could be over 60 billion habitable planets in our Milky Way alone. This estimate is about twice the previous estimates of at least one Earth-sized planet in the habitable zone of each red dwarf star.

Publishing in:

Astrophysical Journal Letters

Study Further:

Previous estimate was made by the researchers from Harvard University and this new thinking has been reported by the researchers from the University of Chicago and Northwestern University.

This new estimate has been made by considering “cloud cover”. Cloud cover is the concept given to the dayside of the exoplanets that are tidally locked i.e. one hemisphere of the planet continually faces the star (dayside), while the other faces away (darkside). It was thought that dayside would have high level of stellar flux but recent computer simulations showed otherwise due to the presence of clouds.

Cloud cover could be the reason that “tidally locked planets have low enough surface temperatures to be habitable,” explained Jang in his recently published paper.

Red dwarfs “represent about ¾ of the stars in the galaxy, so it applies to a huge number of planets,” Dr. Abbot, co-author on the paper, told Universe Today.

Future observations will approve or disprove this finding by measuring the cloud temperatures and James Webb Space Telescope would be one of the better options to study.
