#Structured Illumination Microscopy and SPA Help Study SPB Duplication in Living Yeast Cells Cellular mitosis depends in part on small organelles that extend spindles to pull apart chromosome pairs.
Now, a team of researchers from the Stowers Institute for Medical Research and the University of Colorado Boulder has devised a novel optical technique--a combination of structured illumination microscopy (SIM
"The use of SIM to study SPB structure completely changes the types of questions we can ask and answer,
and it is likely that SIM will work in living cells, "says Sue Jaspersen, Ph d,
The research team turned to SIM as an optical alternative. SIM uses a laser-generated field of horizontal lines to project an interference pattern onto a sample.
According to Jay Unruh, Ph d.,a Stowers research advisor and co-author, analyzing these patterns enables researchers to effectively double their resolution."
"For all of its advantages, SIM still involves sifting through a great deal of noise. To deal with this problem,
often with even greater precision than via SIM alone,"says Jaspersen.""We estimate the precision to be in the 10-30 nm resolution range."
"The SPA-SIM technique made up part of a two-color structured illumination microscopy approach that used endogenously expressed fluorescent protein derivatives.
According to Unruh, this study represents the first combined use of SPA with SIM, and one of the first dual-color super-resolution SPA papers.
According to Jaspersen, the SPA-SIM technique is applicable to a wide variety of subjects beyond SPB structure."
In a study to be published on the elife website on September 15 2015, a team of researchers from the Stowers Institute for Medical Research and the University of Colorado Boulder combined two optical systems in a new way to get around the natural limits of optical microscopes.
One, called structured illumination microscopy (SIM), makes laser-based interference patterns that change based on what they interact with,
#Platelet-Mimicking Nanoparticles Could Effectively Deliver Drugs to Targeted Sites Nanoparticles disguised as human platelets could greatly enhance the healing power of drug treatments for cardiovascular disease and systemic bacterial infections.
San diego, are capable of delivering drugs to targeted sites in the body--particularly injured blood vessels,
and release their drug payloads specifically to these sites in the body. Enclosed within the platelet membranes are made nanoparticle cores of a biodegradable polymer that can be metabolized safely by the body.
The nanoparticles can be packed with many small drug molecules that diffuse out of the polymer core and through the platelet membrane onto their targets.
To make the platelet-membrane-coated nanoparticles, engineers first separated platelets from whole blood samples using a centrifuge.
the platelet membranes were broken up into much smaller pieces and fused to the surface of nanoparticle cores.
Researchers observed that the docetaxel-containing nanoparticles selectively collected onto the damaged sites of arteries

#Nanostructure Changes Colour When Finger Comes Near Touchscreens suffer from mechanical wear over time and are a transmission path for bacteria
What they really want is to use it in touchless displays. ecause these sensors react in a very local manner to any increase in moisture,
it is quite conceivable that this sort of material with moisture-dependent properties could also be used for touchless displays
and monitors, said Ganter. Touchless screens of this kind would require nothing more than a finger to get near the display to change their electrical or optical properties and with them the input signal at a specific point on the display.
Taking phosphatoantimonate nanosheets as their basis the Stuttgart scientists then developed a photonic nanostructure which reacts to the moisture by changing colour. f this was built into a monitor,
the users would then receive visible feedback to their finger motionexplained Katalin Szendrei, also a doctoral student in Bettina Lotsch group.
To this end, the scientists created a multilayer sandwich material with alternating layers of ultrathin phosphatoantimonate nanosheets and silicon dioxide (Sio2) or titanium dioxide nanoparticles (Tio2.

#Graphene Shows Potential for Energy-efficient Data storage Technologies Graphene can be used to produce energy-efficient, high-density memory chips.
Researchers at Stanford used graphene in three different ways to create data storage technology that has the best features of both volatile and nonvolatile silicon chips.
Phones, laptops and other electronic devices all use memory chips to function. To be desireable they must be fast,
Engineers are presently trying to develop nanomaterial-based memory chips that perform better than their silicon counterparts to be used in low energy data centers and gadgets with a longer battery life.
Data is stored by memory chips in the form of ones and zeroes. Silicon-based memory chips are classified as either volatile and nonvolatile.
Volatile memory can store data only when power is available. Random access memory (RAM) is an example of volatile memory.
Nonvolatile memory is slow but stable and it continues to store the data even when power is not available.
The flash memory used in cell phones is an example of nonvolatile memory. Engineers led by Stanford have demonstrated a way to create memory that combines the stability of flash memory with the speed of RAM.
They used new technologies and materials to create memory that consumed comparatively less energy than silicon.
In the RRAM chips metal oxides are changed between conductive and resistive states by the application of a small joly of electricity. in these RRAM chips.
A zero is created when the electron flow is resisted by the metal oxides, and a one is created
Like flash memory, RRAM has the ability to store data without power, and it is also fast like volatile silicon memory.
This enables fabrication of smaller RRAM cells that have the capacity to store more data than conventional metal-based conductors.
This material has the ability to store data even when power is not available. Pop and Wong state that graphene unique

VLC encodes data into light intensity changes at a high frequency imperceptible to human eyes. Unlike conventional radio frequency systems that require complex signal processing,
VLC uses energy efficient light emitting diodes to transmit data inexpensively, securely, cleanly and with virtually unlimited bandwidth.
Any devices equipped with light sensors can recover data by monitoring light changes.""Here we are pushing the envelope further and ask:
Can light turn into a ubiquitous sensing medium that tracks what we do and senses how we behave?"

Smart devices such as smart glasses, smart watches and smartphones equipped with photodiodes communicate using VLC.
Users can continuously gesture and interact with appliances and objects in a room-for example, a wall-mounted display,
computers, doors, windows, coffee machine--similar to using the Kinect or Wii in front of a TV.
But there are no cameras (high-fidelity sensors with privacy concerns) monitoring users or any on-body devices or sensors that users have to constantly wear or carry, just LED LIGHTS on the ceiling and photodiodes on the floor.
Compared to existing methods that use wireless radio signals such as Wi-fi to track user gestures, light-based sensing does not introduce electromagnetic interferences
and is limited not to classifying a predefined set of gestures and activities. In their new study
the researchers developed a system called Lisense that uses VLC to reconstruct a human skeleton's movements in real time (60 Hz.
they designed an algorithm to reconstruct human postures using 2-D shadow information with a limited resolution collected by photodiodes embedded in the floor."

#Magnetic Signals Sent through the Human body for Wireless communication Electrical engineers at the University of California, San diego demonstrated a new wireless communication technique that works by sending magnetic signals through the human body.
The new technology could offer a lower power and more secure way to communicate information between wearable electronic devices, providing an improved alternative to existing wireless communication systems,
researchers said. They presented their findings Aug 26 at the 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society in Milan, Italy.
such as smart watches, fitness trackers and health monitors. All of these devices will need to communicate information with each other.
Currently, these devices transmit information using Bluetooth radios, which use a lot of power to communicate. We're trying to find new ways to communicate information around the human body that use much less power,
a professor in the Department of Electrical and Computer engineering at UC San diego who led the study.
Communicating magnetic signals through the human body The new study presents a solution to some of the main barriers of other wireless communication systems:
Bluetooth technology uses electromagnetic radiation to transmit data, however these radio signals do not easily pass through the human body
and therefore require a power boost to help overcome this signal obstruction, or"path loss."
Researchers showed that the path losses associated with magnetic field human body communication are upwards of 10 million times lower than those associated with Bluetooth radios."
"This technique, to our knowledge, achieves the lowest path losses out of any wireless human body communication system that's been demonstrated so far.
This technique will allow us to build much lower power wearable devices, "said Mercier. Lower power consumption also leads to longer battery life."
"A problem with wearable devices like smart watches is that they have short operating times because they are limited to using small batteries.
With this magnetic field human body communication system, we hope to significantly reduce power consumption as well as how frequently users need to recharge their devices,
Since this technique is intended for applications in ultra low power communication systems the transmitting power of the magnetic signals sent through the body is expected to be many times lower than that of MRI SCANNERS and wireless implant devices.
Another potential advantage of magnetic field human body communication is that it could offer more security than Bluetooth networks.
Because Bluetooth radio communicates data over the air, anyone standing within 30 feet can potentially eavesdrop on that communication link.
To put this in the context of a personal full-body wireless communication network, information would neither be radiated off the body nor be transmitted from one person to another."
when you're using your wearable devices to transmit information about your health, "said Park. Demonstrating magnetic communication with a proof-of-concept prototype The researchers built a prototype to demonstrate the magnetic field human body communication technique.
The technology was among the top award winners in the Texas instruments Innovation Challenge this past summer.
The technology, developed in collaboration with Texas instruments, represents a growing interest in the development of high-tech sign language recognition systems (SLRS) but unlike other recent initiatives,
and the videos or images captured may be considered invasive to the user privacy. What more, because these systems require a user to gesture in front of a camera,
they have limited wearability and wearability, for Jafari, is key.""Wearables provide a very interesting opportunity in the sense of their tight coupling with the human body,
This sensor plays a major role in discriminating different signs by capturing the user hand orientations and hand and arm movements during a gesture.
In Jafari system both inertial sensors and electromyographic sensors are placed on the right wrist of the user where they detect gestures
and send information via Bluetooth to an external laptop that performs complex algorithms to interpret the sign
and display the correct English word for the gesture. As Jafari continues to develop the technology,
he says his team will look to incorporate all of these functions into one wearable device by combining the hardware and reducing the overall size of the required electronics.
He envisions the device collecting the data produced from a gesture, interpreting it and then sending the corresponding English word to another person smart device
so that he or she can understand what is being signed simply by reading the screen of their own device.

#EU votes down net neutrality protection The European parliament has voted against a set of rules intended to safeguard"net neutrality"in the EU. A series of amendments to a regulation on how internet traffic is managed in Europe were rejected all by MEPS.
Proponents of net neutrality, who demand that web traffic be treated equally by networks, have criticised already the move.
Campaigners have said that provisions for protecting net neutrality in the existing text of the rules are too vague and many worry that it will be easy for internet firms to strike deals with content providers
in which customers can access certain sites and services for free outside their data plans, might become more widespread.
While this could be beneficial for those who want to access content from those providers, others worry that it will stifle innovation.
It is thought that many MEPS would have been reluctant to begin a process of amending the regulation given that it might have delayed another aspect of the rules-the abolition of mobile data roaming charges.
what we use the internet for in 2015 is vastly different from those early days when Tim Berners-Lee was inventing the web,
"commented Chris Green of business consultancy Lewis as he pointed out that the rise of video streaming had placed extra burdens on network companies."
"For them, a two-tier internet makes much more sense, "he told the BBC. What is net neutrality?
The idea that data should be ferried from place to place as quickly as possible, regardless of
is how most people assume the internet works. That's the essence of net neutrality.
However, it's possible to decide to prioritise certain types of data over others-perhaps, for example,
by charging the producers of such data a fee to make sure their content gets delivered promptly.
For big video streaming sites, the prospect is worrying. They could find themselves coughing up lots of money in fees simply to give their users the same experience as before.
Some argue however, that such fees are fair since it costs internet service providers a lot of money to keep providing such content,
no matter how popular the streaming sites become. How could the rules affect internet use? Part of the problem with the rules in their current form, argued Joe Mcnamee at the European Digital Rights campaign group,
is that they are ambiguous.""As the text currently stands there is no indication as to how much abuse of dominance would be permissible under this arrangement,
The sort of scenarios that could impact internet use include the creation of"fast lanes"and"slow lanes"or the creation of"zero ratings"in
which some services may be accessed without using up any of the internet user's data quota. In Belgium, for example, some mobile phone companies currently allow unlimited access to Twitter
and Facebook while all other data usage is part of a monthly plan. In a few countries such as The netherlands
such practices are allowed not. Who had argued that the amendments be adopted? Besides a host of net neutrality campaigners, inventor of the world wide web Sir Tim Berners-Lee had added his voice to those supporting the amendments."

And a string of tech companies signed a letter to the president of the European parliament, Martin Schulz,
