Foreshocks predict earthquakes!

      

After a destructive earthquake, scientists sifting through the rumbles that preceded the big event often find foreshocks.
Foreshocks are smaller temblors that strike in the days and hours before a moderate-to-large earthquake. They’re puzzling. Not all earthquakes have foreshocks, and despite decades of effort, no one has successfully found a way to predict earthquakes using foreshocks.

Global internet slows after ‘biggest attack in history’

Inside an Israeli Defense Lab

Israeli military specialists and university researchers are developing new drones and new ways to protect buildings and buses from attack. Israel's Unmanned Aerial Vehicle squadron uses this military drone, The Heron, to keep watch on Lebanon, the West Bank, and Gaza (UAV officers cannot comment on any other locations the drones are currently deployed to). 

Rare sharks near Australia

A rare shark couple found for the first time off the coast of Australia may force a rethink of the species’ range.
 

   Two years ago, a sport fisherman caught a pair of rare sharks off Rottnest Island in Western Australia. The duo, a male shark about 3.3 feet (1 meter) long and a pregnant female about 3.9 feet (1.2 m) long,

Missing link in taste chain

Protein sends message to brain that tongue has detected sweet, bitter or umami flavor.
 

     When something leaves a bad taste in your mouth or a good one  you might blame a newly pinpointed protein. Experiments using mice have revealed a key player in the chain of events that lets the brain know what the tongue has tasted.

New radiation ring around earth

High above Earth’s surface float two rings of energetic charged particles, and for about four weeks in September, they were joined by a third. The temporary ring may have formed in response to a solar shock wave that passed by Earth, researchers report online February 28 in Science.
The discovery could force scientists to revisit decades of ideas about the structure of the Van

What is Sleeping Beauty transposon?

The Sleeping Beauty transposon system is a synthetic DNA transposon that was constructed to introduce precisely defined DNA sequences into the chromosomes of vertebrate animals for the purposes of introducing new traits and to discover new genes and their functions.

When Earth was snowball

For decades, scientists have intended that the earth may once have been a “Snowball Earth,” and new research proposes oceans could have churned beneath an ice-covered Earth, possibly assisting to provide life with vital nutrients. When ice possibly swathed the entire world, the oceans underneath may have nevertheless surprisingly churned, potentially helping to provide life with vital nutrients, new research suggests.
For decades, scientists have proposed that the planet may once have been a “Snowball Earth,” with geological evidence suggesting ice reached all the way to the equator at least twice during the Neoproterozoic era (about 635 million to 750 million years ago)

Solar system-like planet

A team of astronomers, including Quinn Konopacky of the Dunlap Institute for Astronomy & Astrophysics, University of Toronto, has made the most detailed examination yet of the atmosphere of a Jupiter-like planet beyond our Solar System.

According to Konopacky, “We have been able to observe this planet in unprecedented detail because of the advanced instrumentation we are using on the Keck II telescope, our ground-breaking observing and data-processing techniques, and because of the nature of the planetary system.”

Scientists claim new glasses-free 3D for cellphone

Fancy watching a movie on your mobile phone, where figures leap out from the screen in 3D, rather as Princess Leia did in that scene from “Star Wars”?
That’s the claim made by US researchers, who on Wednesday reported they had made a display which gives a three-dimensional image that can be viewed without special glasses and is intended for cellphones, tablets and watches.
Unlike the holographic projection used in George Lucas’ movie fantasy, their small prototype display is flat and backlit.
It uses a technology called diffractive optics to give 3D images that can be viewed from multiple angles, even if the device is tilted.

YouTube reaches one billion monthly users

YouTube, the video sharing site owned by Google, has announced it has passed one billion regular users.
Announcing the milestone on its blog, the site said a recent growth in smartphones had helped boost the numbers visiting the site every month.
YouTube’s popularity provides Google with a lucrative channel through which to sell advertising, alongside its core search business.
YouTube was launched in 2005 and bought by Google in 2006.
It paid $1.76bn (£1.16bn) for the site, which at the time had an estimated 30-40 million users world wide.

Prospect of Martian life?

If a microorganism were found on Mars, would anyone care?
NASA scientists announced on March 12 that the Red Planet could have supported ancient life  though they don’t yet have evidence that it did. A sample of rock drilled by the Curiosity rover revealed conditions that could have supported ancient microbes at some point in the distant past.
The news of even potential life made headlines, and there’s no doubt the discovery of actual microbial life on Mars would, too. But the impact of finding

Earthquakes with Midas touch

The tyrannosaur of the minerals, this gold nugget in quartz weighs more than 70 ounces (2 kilograms).

            Water in faults vaporizes during an earthquake, depositing gold, according to a model published in the March 17 issue of the journal Nature Geoscience. The model provides a quantitative mechanism for the link between gold and quartz seen in many of the world’s gold deposits, said Dion Weatherley, a geophysicist at the University of Queensland in Australia and lead author of the study.
When an earthquake strikes, it moves along a rupture in the ground

Chittagong to get 3G this month

Voyager now in solar system border

Voyager 1, launched in 1977 to explore the outer planets, has passed into a new region on its way out of the solar system, scientists said on Wednesday.

The spacecraft, now more than 11 billion miles (18 billion km) away, detected two distinct and related changes in its environment on August 25, 2012, scientists write in paper to be published in Geophysical Research Letters and emailed to Reuters on Wednesday.

The probe detected dramatic changes in the levels of two types of radiation, one that stays inside the solar system, the other which comes from interstellar space.

Samsung Galaxy S4 launched

Samsung Electronics Co on Thursday premiered its latest flagship phone, the Galaxy S4, which sports a bigger display and unconventional features such as gesture controls and will spearhead its effort to challenge Apple Incon its home turf.The phone is the first in Samsung's highly successful Galaxy S-series to make its global debut on US soil, and represents another bet that consumers prefer larger screens.

The S4 - which Samsung preceded with a marketing blitz that drummed up industry speculation reminiscent of some of Apple's past launches - will be available globally in the second quarter. Samsung said all major US service providers will sell the phone but it kept mum on exact dates and prices.

2013: The Year of The Android?

          This year’s generation of Android phones show a lot of promise, but the big challenge now for phone manufacturers is to produce the true jaw-dropper that deviates from the classic candy-bar design. It may not happen in 2013, but it’s safe to say that Android phones are hitting their stride and even more great design is on the horizon.

         While the bulk of the CES 2013 announcements were mainly focused on bigger and better Ultra HD televisions, we believe that full-HD smartphones will be the next big thing.

Android Smartphones Are Growing Up
