First place! Even sperm cells from the same man have big genetic differences, a study has shown
If the two DNAs of the Sperm of an individuals differ,how come the DNA Tests are fail Proof?
Why do the DNAs differ?
Cause could be explained only by accepting predetermination, you call it Biological Laws,Nature, God,Or Reality?
Do the days on which Intercourse takes place have any bearing on this?
Science explains Hows and Never Whys.
If two Cells of the same Organ of the same individual are not Identical, how is it that we say All are Born Equal?
Story:
The ‘race’ betweeen human sperm to the eggs might just look like a bunch of wriggling tadpoles – but it makes a big difference which sperm wins.
Even sperm cells from the same man have big genetic differences, a study has shown.
For the first time, scientists have obtained genetic blueprints of almost 100 sperm from a single individual
The results confirm what scientists already know, that every sperm is different because of the way their inherited DNA is shuffled.
The process, known as recombination, mixes up genes passed down by a man’s mother and father and increases genetic diversity.
Each of the 91 sperm studied showed an average of 23 recombination, or mixing, events. But individual sperm varied greatly in the way they experienced spontaneous genetic mutations.
Every sperm contained between 25 and 36 ‘new’ mutations, not seen in other body cells.
Two sperm were found to be missing entire chromosomes, the protein-bound packages of DNA that contain the genes.
Random mutations create genetic variation, but can be harmful if they occur in the wrong places.
The cells were donated by a 40-year-old man who has healthy offspring and normally functioning sperm.
‘For the first time we were able to generate an individual recombination map and mutation rate for each of several sperm from one person,’ said Professor Barry Behr, from Stanford University in California, US.
‘Now we can look at a particular individual, make some calls about what they would likely contribute genetically to an embryo, and perhaps even diagnose or detect potential problems.’
Genetically sequencing sperm could provide a ‘new kind of early detection system’ to identify men who may have trouble conceiving, he added.
The research is published today in the journal Cell.
The US had sent an unmanned Space Shuttle Air force with sophisticated instruments sent a year ago has landed in Vandenberg .
The Details are reported to be classified.
Weaponizing Space?
One wonders that with all the machinery and gadgets one can think of, the US always loses a War, save the Second World War(that too with a combined Effort)
What does this imply?!
Story:
(Reuters) – The U.S. military’s unmanned X-37B robotic space shuttle returned from orbit at 5:48 a.m. in California (1248 GMT)from a secretive 15-month test flight, Air Force officials said on Saturday.
The miniature space plane, also known as Orbital Test Vehicle-2, or OTV-2, touched down at California’s Vandenberg Air Force Base, 130 miles (209 kilometres) northwest of Los Angeles. It was only the second U.S. vehicle to make an autonomous runway landing from space.
“With the retirement of the space shuttle fleet, the X-37B OTV program brings a singular capability to space technology development,” said Lieutenant Colonel Tom McIntyre, X-37B program manager. “The return capability allows the Air Force to test new technologies without the same risk commitment faced by other programs. We’re proud of the entire team’s successful efforts to bring this mission to an outstanding conclusion.”
The military’s first X-37B debuted in 2010 and autonomously landed at Vandenberg after 224 days in space. The former Soviet Union’s Buran space shuttle, which made a single spaceflight in 1988, was the first ship to make an autonomous landing from orbit.
The military will not disclose what OTV-2 was doing during its 15 months in orbit, but a third mission already is on the calendar for launch this fall. OTV-2 blasted off aboard an unmanned Atlas 5 rocket from Cape Canaveral Air Force Station on March 5, 2010.
The military, which took over the program from NASA, says it is using them to learn how to quickly and inexpensively refurbish reusable spaceships for flight. The X-37Bs also serve as orbital test beds for instruments that could be incorporated into future satellites.
It is not known if it carried anything in its cargo bay, which is about the size of a pickup truck bed.
The vehicles look like miniature versions of NASA’s now-retired space shuttle orbiters, with a similar shape and a payload bay for cargo and experiments.
They are 29 feet (8.9 metres) long, compared to the shuttle’s 122-foot (37-metre) length, and have a wingspan of 15-feet (4.5 metres), compared to the shuttle’s wingspan of 78 feet (23.7 meters).
Rather than hydrogen-oxygen fuel cells like the orbiters, the X-37Bs are powered by gallium arsenide solar cells with lithium-ion batteries. The vehicles were designed to stay in orbit for up to 270 days. OTV-2 surpassed that milestone by 199 days.
Under the concept of sharing privacy goes through the window!
Dear Facebook (Photo credit: JAMES ANTHONY CAMPBELL)
If people have good intentions about sharing they would use their real names, provided their names are available.
The judgement is correct.
Facebook Inc has agreed to pay $10 million to charity to settle a lawsuit that accused the site of violating users’ rights to control the use of their own names, photographs and likenesses, according to court documents made public over the weekend.
The lawsuit, brought by five Facebook members, alleged the social networking site violated California law by publicizing users’ “likes” of certain advertisers on its “Sponsored Stories” feature without paying them or giving them a way to opt out, the documents said.
A “Sponsored Story” is an advertisement that appears on a member’s Facebook page and generally consists of another friend’s name, profile picture and an assertion that the person “likes” the advertiser.
The settlement was reached last month but made public this weekend. Facebook declined to comment on Saturday.
The proposed class-action lawsuit, filed in federal court in San Jose, California, could have included nearly one of every three Americans, with billions of dollars in damages, according to previous court documents.
In the lawsuit, Facebook Chief Executive Mark Zuckerberg was quoted as saying that a trusted referral was the “Holy Grail” of advertising.
In addition, the lawsuit cited comments from Facebook chief operating officer Sheryl Sandberg, saying that the value of a “Sponsored Story” advertisement was at least twice and up to three times the value of a standard Facebook.com ad without a friend endorsement.
U.S. District JudgeLucy Koh said the plaintiffs had shown economic injury could occur through Facebook’s use of their names, photographs and likenesses.
“California has long recognized a right to protect one’s name and likeness against appropriation by others for their advantage,” Koh wrote.
The settlement arrangement is known as a cy-pres settlement, meaning the settlement funds can go to charity.
A taxi Service in Mumbai has come out with Aandroid Application to pick up, drop the Customers.
The normal process of calling the Help Line, waiting toget through is eliminated in this service.
The Cab Drivers are provided with Smartphone and all the customer has to do is to click the web,Telebooking platform and they are connected with the cab driver who happens to be nearest gets connected and you get the details like the time needed to reach you and the journey time to your destination.
The organisation Olacabs is planning to extend this service to smaller towns as well shortly.
The concept of vehicle pooling was prevalent in metro cities. I launched the website in Ahmedabad in June last year with aim of reducing people’s fuel costs and promoting environmental cause. Also, it helps people in networking and making new friends. Once the user uploads his route and requirements, we provide him with matching profiles. He can contact them directly and discuss further details,” said Suresh Purohit, an entrepreneur who started http://www.olivetrips.com that offers car pooling service for free.
About 275 Gujaratis are availing benefits of vehicle sharing through his site and the number is increasing every month.
Purohit, an MBA graduate said that trend of vehicle pooling will pick up faster when people know about such website and understand benefits of sharing system.
City-based entrepreneur Ruchira Choudhuri Saikia has gone a step ahead and introduced the concept of socializing through vehicle pooling website.
“We are introducing chat, video and status update facilities on our website (www.greenyatri.com) that will be launched within a month. Those logging onto the website can find partners for vehicle pooling, chat with other users and work out the sharing plans. Also, they can upload videos or pictures related to traffic issues in the city. The experience will be similar to some popular networking sites,” Ruchira told TOI.
Their focus is to reduce environment pollution and congestion on roads.”
