Tragic death of a Chinese women using iPhone 5 while charging
An Apple employee looks over a new iPhone 5 at a Verizon Communications Inc. store in Orem, Utah, Sept. 20, 2012. |
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
(This article has been cross-posted from SayPeople.com)
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

Over 60 billion habitable planets probably present in our Milky Way (Credit: mickare/deviantart) |
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.

Headphone utilizing solar power to charge mobile devices
(This article first published on jeeget.blogspot.com)
You would soon get, probably by the start of next year,
solar headphones that will come with the power of charging your mobile devices
through solar power.
This OnBeat headphone has been launched by Andrew Anderson
on the crowdfunding website Kickstarter. Anderson is expecting to raise
£200,000 to start the mass production of headphones.
This headphone is fitted with a flexible solar cell with a
charge capacity of 0.55 watts and the generated energy will be stored in two
small lithium batteries.
"We are still working on the design and
prototype," he told the BBC.
"We need to improve the headphones - people want to
know about noise cancellation."
Green energy is gaining huge popularity among the users and
this headphone would be a good thing.
