Thermodo thermometer for smart phones

Thermodo is a tiny electrical thermometer that measures the temperature of  your  Android, iPhone/iPad, Windows Phone and also other smartphones.

Thermodo:

Thermodo is a sleek little thermometer with accurate and expertly built hardware that we can have with us everywhere. Its is designed and produced by robocat. Thermodo consists of a passive temperature sensor built into a standard 4 pole audio jack enclosed by a sturdy housing. This allows your mobile device to read Thermodo’s temperature straight from the audio input. Thermodo sends an audio signal through the temperature sensor. This sensor will then attenuate the signal amplitude depending on the actual temperature. This attenuation can now be detected on the microphone input and through software we calculate the corresponding temperature.  Simply plug Thermodo into your device and start the companion app or any other Thermodo enabled apps of your choice. The temperature reading takes place instantly. Thermodo is powered by your device. No external power is required, it can even run in the background while you do important stuff.we can use it anywhere indoor or may be in outdoors.

Its cost just $19 that’s the main and attractive point in it!!!!!!

carefull and alert in ATM centre…

Police are warning credit card and bank card holders to exercise caution when using ATMs and other “swipe” machines was found fitted with devices capable of recording card data and pin numbers..

These numberpads will record your pin number and after you leaving the pin number,password will be used.. So be alert in ATM centre..

Generate clean electricity from Bacteria

British scientist have discovered that electricity can be generated by bacteria.Proteins on the surface of the bacteria can produce an electric current by simply touching a mineral surface.  It is possible for bacteria to lie directly on the surface of a metal or mineral and transfer electrical charge through their cell membranes. This means that it is possible to tether bacteria directly to electrodes. It helps the scientist to create efficient microbial fuel cells or bio-batteries.

University of East Anglia scientist are working with a marine bacteria called Shewanella oneidensis. They created a synthetic version of this bacteria using just the proteins thought to shuttle the electrons from the inside of the microbe to the rock. They inserted these proteins into the lipid layers of vesicles, which are small capsules of lipid membranes such as the ones that make up a bacterial membrane. Then they tested how well electrons travelled between an electron donor on the inside and an iron-bearing mineral on the outside.

Dr. Tom Clarke Lead researcher from UEA’s  school of biological science said,   “We knew that bacteria can transfer electricity into metals and minerals, and that the interaction depends on special proteins on the surface of the bacteria. But it was not been clear whether these proteins do this directly or indirectly though an unknown mediator in the environment”.
He also added that,”Our research shows that these proteins can directly touch the mineral surface and produce an electric current, meaning that is possible for the bacteria to lie on the surface of a metal or mineral and conduct electricity through their cell membranes.
This is the first time that we have been able to actually look at how the components of a bacterial Cell-Membrane. cell membrane are able to interact with different substances, and understand how differences in metal and mineral interactions can occur on the surface of a cell.
These bacteria show great potential as microbial fuel cells, where electricity can be generated from the breakdown of domestic or agricultural waste products”.

Liang Sh, a biochemist from Pacific Northwest National Laboratory said, ” We developed a unique system so we could mimic electron transfer like it happens in cells. The electron transfer rate we measured was unbelievably fast. it was fast enough to support bacterial respiration.”

 

Giant radio galaxy discovered

Astronomers have discovered a unknown gigantic radio galaxy, using initial images from a new, ongoing all-sky radio survey.

The galaxy was found using the powerful International LOFAR Telescope (ILT), built and designed by the Netherlands astronomical foundation ASTRON. The team is currently performing LOFAR’s first all-sky imaging survey, the Multi-frequency Snapshot Sky Survey.

While browsing the first set of MSSS images, Dr George Heald identified a new, huge source that represents material ejected from one member of an interacting galaxy triplet system tens to hundreds of millions of years ago.

The new galaxy is a member of a class of objects called Giant Radio Galaxies (GRGs). GRGs are a type of radio galaxy with extremely large physical size, suggesting that they are either very powerful or very old.

The center of the new GRG is associated with one member of a galaxy triplet known as UGC 09555. The central galaxy is located 750 million light years from Earth.

The central radio source was previously known and has a flat radio spectrum, typical of giant radio galaxies. LOFAR is an effective tool to find new GRGs like this one

because of its extreme sensitivity to such large objects, combined with its operation at low frequencies that are well suited to observing old sources.

LOFAR’s MSSS survey is a concerted effort to image the entire northern sky at very low radio frequencies, between 30 and 160 MHz (wavelengths from 2m to 10m). The primary aim of the survey is to perform an initial shallow scan of the sky, in order to create an all-sky model that will support the calibration of much deeper observations.

The international team of astronomers that is performing the MSSS survey is made up of about fifty members from various institutes, mostly in the Netherlands, Germany, the UK, Poland, France and Italy.

NASA Hubble Space Telescope

This is a NASA Hubble Space Telescope picture of a comet-like object called P/2010 A2, which was first discovered by the LINEAR (Lincoln Near-Earth Asteroid Research program) sky survey on January 6, 2010. The object appears so unusual in ground-based telescopic images that discretionary time on Hubble was used to take a close-up look. This picture, from the January 29 observation, shows a bizarre X-pattern of filamentary structures near the point-like nucleus of the object and trailing streamers of dust.

The inset picture shows a complex structure that suggests the object is not a comet but instead the product of a head-on collision between two asteroids traveling five times faster than a rifle bullet (5 kilometers per second). Astronomers have long thought that the asteroid belt is being ground down through collisions, but such a smashup has never before been seen.

The filaments are made of dust and gravel, presumably recently thrown out of the 460-foot-diameter nucleus. Some of the filaments are swept back by radiation pressure from sunlight to create straight dust streaks. Embedded in the filaments are co-moving blobs of dust that likely originate from tiny unseen parent bodies. An impact origin would also be consistent with the absence of gas in spectra recorded using ground-based telescopes.

At the time of the Hubble observations, the object was approximately 180 million miles (300 million km) from the Sun and 90 million miles (140 million km) from Earth. The Hubble images were recorded with the new Wide Field Camera 3 (WFC3). The image was taken in visible light. The color in the image is not what the human eye would see. A blue color map was added to bring out subtle details.
