SAM Found Oraganic matter on MARS - Scientists are very excited after decades of research

There’s big news coming out of the Sample Analysis at Mars instrument suite (SAM) on NASA’s Curiosity rover. For the first time, organic matter has definitively been detected on Mars. In addition to finding organic compounds in rocks, SAM has also detected sharp increases and decreases in methane levels in the atmosphere. MSL participating scientist, Danny Glavin, explains these findings and what they tell us about our search for life on the Red Planet.

Scientists Put A Worm's Mind Into A Robot's Body - Its impeccable

Posted by vishnu vardhan reddy boda at 9:41 AM
Yes, Thats true. They Connected Worm's brain to a robot and robot worked according to worm's brain.




Beneath the skin of a simple worm with transparent skin, there are 302 neurons that have been mapped meticulously by researchers in what is known as a connectome. This tiny, one millimeter-long worm has been studied in laboratories around the world, and now it's nervous system has been transplanted into the body of a Lego Mindstorms EV3 robot. The worm they used is Caenorhabditis elegans (C. elegans).

Why? According to OpenWorm—an organization dedicated to creating the world’s first virtual organism in a computer—to understand the human brain, we must first be able to comprehend a simple worm. To do so, their scientists essentially reverse-engineered the worm’s neural networks using sensors and software. The model makes use of UDP packets to fire neurons. For example, the sonar sensor on the robot is wired to be like the worm’s nose, which means if the robot comes within 20 centimeters of an object, sensory neurons are activated with UDP packets.

Apparently, the robot acts a lot like C. elegans: Stimulation of its nose made it stop moving, while touching a food sensor made it move forward. “What we found is that rather than just random, crazy movements by the robot, it actually responded to its environment in the same manner as the biological worm,” said Timothy Busbice, one of the founders of the OpenWorm project, to Gizmodo.




Busbice has posted a video of the accomplishment to Youtube. While the Lego Robot can’t wriggle like a worm and the video is not exactly thrilling to watch, it is interesting to see what can be achieved in a robot with no instructions programmed into it. 
“The key point is that there was no programming or learning involved to create the behaviors,” said Lucy Black for I Programmer. “The connectome of the worm was mapped and implemented as a software system and the behaviors emerge.” Thanks for IFLScience team for framing the article.

A Bullet that Aims itself. Self Guided Sniper Bullets is not a Fantasy any more, DARPA developed it. watch video here.

Not Just in James Bond movies, its time for reality with self guided bullet sniper rifles.


DARPA's Extreme Accuracy Tasked Ordnance (EXACTO) program recently conducted the first successful live-fire tests demonstrating in-flight guidance of .50-caliber bullets.

This video shows EXACTO rounds maneuvering in flight to hit targets that are offset from where the sniper rifle is initially aimed. EXACTO's specially designed ammunition and real-time optical guidance system help track and direct projectiles to their targets by compensating for weather, wind, target movement and other factors that could impede successful aim. 
Here is the video of official tests.

If you have WIFI Router in your home, You need to go change this setting right now before you get hacked.

Posted by vishnu vardhan reddy boda at 1:28 AM
Do you know that there is a special interface which you can access and make tons of changes.  

Making use of it will keep you safe as well as makes your internet connection customizable according to your needs. 

Your router default credentials are universal and every one can access it who is in your wifi range. Its not at all advisable to just use your wifi and leave settings in the air.
If a user can get access to your wifi network, he can not only use your wifi but he can access all the stored in your computer and take control of your wifi. 

It always better and safe to change the interface credetials. Other wise somebody who is your wifi zone may steal your wifi and your privacy by invading in to your network without your notice. 

To access your router internal settings follow below steps. 

Go to this ip address 192.168.0.1 ( type in browser adress bar) 

Userid : admin
Passowrd: Leave Blank or admin

if you cant access the above settings. try this method. 

Go to windows command promt by following the instructions given below.


=> Press windows key + R  and enter cmd in it or just type command prompt in your start menu. It should show up. when you open it, you will something like the below picture.




=>Enter ipconfig.

You will see a bunch of different adapters listed. choose your adapter, if you are on wifi it says wifi adapter or for ethernet it says LAN.

Once you choose wifi adapter (highlighted above), you will see a ip address similar to 192.168.0.1 or 192.168.0.2.

Thats your default gateway. Enter that url in your address bar.

Now try again with same user id and password mentioned above. if you still cant access it means your network provider or the guy who set up internet for you has blocked it or assigned a user id and password.

There is also a chance that you might have been already hacked by some one around and they might have changed the access id and password.

Contact your ISP or reset your router rigth away. 

If you need any assitance with resetting the router, please leave a comment.

If you need any assitance with changing degault user id and password please leave a comment below. 

I will follow up and write new articles for them. Leave a comment if you like this post.

A New Approach to On-Chip Quantum Computing

Posted by btechbunks at 10:18 PM
New low-power method opens the door for easily fabricating future quantum communication and computing devices
 WASHINGTON, Oct. 2, 2014—Commercial devices capable of encrypting information in unbreakable codes exist today, thanks to recent quantum optics advances, especially the generation of photon pairs—tiny entangled particles of light.  Now, an international team of researchers led by professor Roberto Morandotti of INRS-EMT in Canada, is introducing a new method to achieve a different type of photon pair source that fits into the tiny space of a computer chip.
The team’s method, which generates “mixed up” photon pairs from devices that are less than one square millimeter in area, could form the core of the next-generation of quantum optical communication and computing technology. The research will be presented at The Optical Society's (OSA) 98th Annual Meeting, Frontiers in Optics, being held Oct. 19-23 in Tucson, Arizona, USA.
One of the properties of light exploited within quantum optics is “photon polarization,” which is essentially the direction in which the electric field associated with the photon oscillates. The research team set out to find a way to directly “mix up,” or cross-polarize, the photons via a nonlinear optical process on a chip.

“While several efforts have been devoted to develop on-chip sources of polarization-entangled photons, the process typically used to generate these photons only allows the generation of photons with the same polarization as the laser beam used to pump the device — either both horizontal or vertical — after

which entanglement can be achieved by accurately mixing these states. Now, we have found a way to directly generate cross-polarized photon pairs,” says Lucia Caspani, a postdoctoral fellow at INRS-EMT and co-author of the Frontiers in Optics paper.
To generate the cross-polarized photons, Caspani and colleagues used two different laser beams at different wavelengths —one vertically polarized and another horizontally polarized.  The approach, however, came with a potential pitfall: the classical process between the two pump beams could destroy the photons’ fragile quantum state.
To address this challenge, the team, which also includes researchers from RMIT University in Australia and City University of Hong Kong, pioneered a new approach based on a micro-ring resonator—a tiny optical cavity with a diameter on the order of tens to hundreds of micrometers—that operates in such a way that energy conservation constraints suppress classical effects while amplifying quantum processes.
While a similar suppression of classical effects has been observed in gas vapors and complex micro-structured fibers, this is the first time it has been reported on a chip, thus opening a clear route for building scalable integrated devices.
“Our approach opens the door to directly mixing different polarizations on a chip,” Caspani points out. “At very low power, our device directly generates photon pairs with orthogonal polarizations, which can be exploited for quantum communication and computing protocols.”
The fabrication process of the chip is also compatible with that currently used for electronic chips. “It enables a future coexistence of our device with standard integrated circuits,” says Caspani, which is a fundamental requirement for the widespread adoption of optical quantum technologies.
Presentation FTu2A.2, “Direct Generation of Orthogonally Polarized Photon Pairs via Spontaneous Non-Degenerate FWM on a Chip,” takes place Tuesday, Oct. 21 at 11 a.m. MST at the Arizona Ballroom, Salon 8 at the JW Marriott Tucson Starr Pass Resort in Tucson.
PRESS REGISTRATION: A press room for credentialed press and analysts will be located in the Marriott, Sunday through Thursday, Oct. 19-23. Those interested in obtaining a press badge for FiO should contact OSA's Lyndsay Meyer at 202.416.1435 or lmeyer@osa.org.
