London: Scientists have developed binoculars which allow users to pause, rewind and playback the objects they were viewing. A devise has been developed, which is similar to the magical devise used by Harry Potter in the Hollywood flick.

Researchers at Sony who developed the devise say that this could revolutionize bird watching, horse racing, cricket and opera watching.

In the film “Harry Potter and Goblet of Fire” such magical devise was shown, and Sony experts claim that this new invention is similar to the imaginary devise.

Sony said its ‘Vinoculars’ or video binoculars are the first devices of their kind in the world. Unlike conventional models which rely on two sets of lenses, the hi-tech version captures images using two miniature cameras positioned in parallel. The images are displayed live on high definition screens in the eye pieces, having the same look and experience of the traditional binoculars. Once the button is pressed, the glasses record images either in ordinary video or in 3D, say Sony experts. The Vinoculars can also capture still photographs, with all the images and videos saved to a memory stick.

Feral chickens have developed an effective countermeasure to avoid being fertilized by a forceful, sub-standard mate.

 Zoologists from Oxford University observed hens forcibly ejecting sperm after copulation, as if to lower a male’s chances of fathering the next generation, and putting a selective pressure on chicken dads.
On average, 80 percent of the ejaculate is expelled. Large quantities suffered a higher risk of ejection, but a larger proportion of smaller ejaculates were expelled leaving less sperm to fertilize an egg.

“Sperm ejection imposes on males an evolutionary dilemma,” says Rebecca Dean, of Oxford University Department of Zoology in a press release. “This trade-off between ejection risk and amount of sperm ejected could generate opposing selection on the evolution of sperm allocation strategies in males.”

Females don’t treat all males equally. The hens were more likely to dump sperm after a few matings, favoring their first partners over later ones. Socially inferior males also got the ejection criteria, as females gave dominant males the advantage.

Female counter-measures to fertilization are not entirely uncommon, and especially prevalent in animals where males are able to force females into mating. It has been found in worms, insects, and even primates.

Male ducks, for example, have large corkscrew penises — lined with ridges and latching spines — that they can extend to a fully-erect 20cm in a a third of a second. To avoid being fertilized by a forceful duck, female ducks have evolved long and twisting maze-like vaginas which spiral in the opposite direction and have dead-end pockets and frightful kinks — it’s like a genitalia arms race.

Do you know the person who has invented CTRL+ALT+DELcommand?

It is David Bradley.

He was an engineer who worked with the IBM for 29 years and retired on March 25, 2005. He has invented this command which every one uses when the computer refuses to obey all other command.

In 1980, Bradley worked as a member of a team of engineers of 12 on this project. Finally Bradley invented it. It took him 1 minute and 23 seconds to develop this command.

Bradley said though he had invented several other thing, this command made him famous. About Bill Gates, Owner of the Microsoft Corporation, he said though he has invented this command, it was Bill Gates who made it famous by adopting it his command for the Windows operating system.

Hyderabad, Aug.2 (NSS):The Directorate of Rice Research (DRR), organized an ‘Innovative
Rice Farmer’s Meet’ in the city today wherein farmers across the nation engaged in growing rice
presented their innovations both in cultivation practices and farm machinery. Aimed to encourage rice
innovators for developing location specific technologies, 25 farmers were felicitated by Shri SK Datta,
DDG(Crop Sciences), ICAR, Shri KD Kokate, DDG(Extension), ICAR, Shri V.Sobhanadreeswara
Rao, Ex-Minister of Agriculture, Govt. of AP Smt. Vijayalaxmi, AD, Agriculture, Govt. of AP and BC

Viraktamath, PD,DRR .
In his inaugural address Shri SK Datta said that innovations are also needed in policy making
understanding the farmer’s perspective. India represents all kinds of diversity under which rice
is grown across the globe, he said. Efforts of combining rice growing in adverse conditions with
those giving high yields need to be documented so that it would encourage participatory technology
development process, he felt.
Saying that the “Farmer’s first” approach at ICAR is redefining the way agricultural research is
conducted, Shri Kokate said that the innovations that have emerged out of farmers’ vast experience and
wisdom should be documented and promoted effectively. He also felt that more efforts were needed to
ensure that rice cultivators get appropriate remuneration for their efforts.
Speaking on the occasion, Shri V.Sobhanadreeswara Rao, former Agriculture minister, voiced
his concern over rampant research on genetically modified rice being carried out in South India, which,
he felt would negatively affect the native varieties. He appealed to the ICAR to consider extending the
ban on GM rice research in Basmati growing areas in the north, to the south as well. He also raised the
issue of insufficient MSP to paddy farmers. Appreciating the efforts of rice innovators he appealed to
the media to highlight their efforts to encourage the farmers.
Details of some farmers who were awarded- Mr Kailash Rana Manger from East Sikkim for
Innovative varietal/landrace selection for local needs, Mr Syed Ghani Khan from Mandya, Karnataka
for identifying and preserving about 140 local varieties, Mr Muppana Pavan Kumar from East
Godavari, AP for identifying crop variety suitable for cyclone prone areas, Mr Rajib Kumar Bhowmik
from Burdhwan, West Bengal for developing arsenic resistant variety of rice as the ground water is
higly arsenic contaminated, Mr Amarjit Singh from Jallandhar, Punjab for new organic techniques to
increase the yield in basmati rice, Mr Bacchu Veera Reddy from Karimnagar, AP for developing new
biopesticide formulation.
All details of the farmers their innovations have been compiled in a publication called ‘Rice
Innovations 2011’ which was released by the guests today. Another booklet and ‘Directorate of
Rice Research in Service of Rice Farmers’ was also brought out. The day long programme will have
presentations by the farmers on their innovations and exchange of perspectives among scientists and
farmers. (NSS)

Sriharikota, July 15 (NSS): PSLV C 17 was successfully launched from the Indian Space Research Centre here at 1648 hrs on Friday. The rocket has completed all the four stages successfully.

            The rocket carried GSAT-12 Communication satellite with a mass of 1410 kg at lift-off, has 12 Extended C-band transponders. PSLV-C17 will inject GSAT-12 into an elliptical Transfer Orbit (Sub-GTO) of 284 km perigee and 21,000 km apogee. Subsequently, the Liquid Apogee Motor of the satellite will be used to raise both apogee and perigee of the Satellite to place it in a circular orbit of 36,000 km altitude.

All the four stages of the launch vehicle have been fully assembled at the Vehicle Assembly Building at Shriharikota.

GSAT-12 satellite has already undergone necessary testing at Shriharikota before commencing the filling of propellants in the Satellite on June 28, 2011. On July 3, 2011, GSAT-12 Satellite is planned to be integrated with PSLV-C17 vehicle at the Vehicle Assembly Building, after clearance by the Launch Authorisation Board.

ISRO Chairman Mr. Radha Krishnan has told the media that the G-Sat 12 has reached its specified orbit successfully. This is the first launch after Mr. Radha Krishnan assumed charge as ISRO Chairman. With the successful launch, the happiness of the scientists of ISRO knew no bounds. They hugged and congratulated each other.

The Rs.200 crore satellite would further improve communications in education, telephone and telemedicine services.

Wednesday’s satellite launch was the 18th launch of PSLV, which has an impressive track record of 16 uninterrupted successes. The PSLV is carrying remote sensing satellite Resourcesat-2 and two mini satellites.

The launch vehicle has placed in polar sun synchronous orbit the 1206-kg Resourcesat-2, 92-kg Youthsat and 106-kg X-sat satellites 822 km above Earth.

The PSLV C16 launch was very important for ISRO as the organisation had experienced two back-to-back failures in 2010. The Geosynchronous Satellite Launch Vehicle plunged down into the Bay of Bengal. ISRO’s four satellites failed in 2010. (NSS)
