A smartphone dongle for diagnosis of infectious diseases at the point of care

Written By: Guest Contributor - Feb• 10•15

This work demonstrates that a full laboratory-quality immunoassay can be run on a smartphone accessory. This low-cost dongle replicates all mechanical, optical, and electronic functions of a laboratory-based enzyme-linked immunosorbent assay (ELISA) without requiring any stored energy; all necessary power is drawn from a smartphone. Rwandan health care workers used the dongle to test whole blood obtained via fingerprick from 96 patients enrolling into care at prevention of mother-to-child transmission clinics or voluntary counseling and testing centers. The dongle performed a triplexed immunoassay not currently available in a single test format: HIV antibody, treponemal-specific antibody for syphilis, and nontreponemal antibody for active syphilis infection. In a blinded experiment, health care workers obtained diagnostic results in 15 min from our triplex test that rivaled the gold standard of laboratory-based HIV ELISA and rapid plasma reagin (a screening test for syphilis), with sensitivity of 92 to 100% and specificity of 79 to 100%, consistent with needs of current clinical algorithms. Patient preference for the dongle was 97% compared to laboratory-based tests, with most pointing to the convenience of obtaining quick results with a single fingerprick. This work suggests that coupling microfluidics with recent advances in consumer electronics can make certain laboratory-based diagnostics accessible to almost any population with access to smartphones.

Ten signs you may be addicted to your smartphone

Watch the video

fdsfsdf

1. When you check your phone to see the current temperature instead of opening a window, and/or when you check your phone to see the current time instead of looking at the watch that’s right on your wrist. (I just did this!)

2. When you have to consciously say to your spouse “Let’s put our phones away” while watching TV because it’s more common that they’re out than away.

3. If you are answering emails in a dimly lit reception area while waiting for your massage therapist to destress you, you may have a problem. (OK, I’ve done this too!)

4. When your kids have to text you their carry-out orders because you’ve lost the ability to retain information that is not received on your phone.

5. When you hope you hit a bunch of red lights on the way home so you can comment on a Facebook post.

6. When one of your daughter’s first drawings of you has a BlackBerry in your hand.

7. When you wake up, you grab your phone and check it before you get up to pee.

8. When you drop a phone on your face because you’re dozing off.

9. When you choose your clothing based on the best pockets to hold your phone.

This drone can steal what’s on your phone

Written By: Guest Contributor - Jan• 14•15

The next threat to your privacy could be hovering over head while you walk down the street.

Capture

This drone can hack your phone

Hackers have developed a drone that can steal the contents of your smartphone — from your location data to your Amazon (AMZN) password — and they’ve been testing it out in the skies of London. The research will be presented next week at the Black Hat Asia cybersecurity conference in Singapore.

The technology equipped on the drone, known as Snoopy, looks for mobile devices with Wi-Fi settings turned on.

Snoopy takes advantage of a feature built into all smartphones and tablets: When mobile devices try to connect to the Internet, they look for networks they’ve accessed in the past.

“Their phone will very noisily be shouting out the name of every network its ever connected to,” Sensepost security researcher Glenn Wilkinson said. “They’ll be shouting out, ‘Starbucks, are you there?…McDonald’s Free Wi-Fi, are you there?”

That’s when Snoopy can swoop into action (and be its most devious, even more than the cartoon dog): the drone can send back a signal pretending to be networks you’ve connected to in the past. Devices two feet apart could both make connections with the quadcopter, each thinking it is a different, trusted Wi-Fi network. When the phones connect to the drone, Snoopy will intercept everything they send and receive.

“Your phone connects to me and then I can see all of your traffic,” Wilkinson said.

That includes the sites you visit, credit card information entered or saved on different sites, location data, usernames and passwords. Each phone has a unique identification number, or MAC address, which the drone uses to tie the traffic to the device.

The names of the networks the phones visit can also be telling.

“I’ve seen somebody looking for ‘Bank X’ corporate Wi-Fi,” Wilkinson said. “Now we know that that person works at that bank.”

CNNMoney took Snoopy out for a spin in London on a Saturday afternoon in March and Wilkinson was able to show us what he believed to be the homes of several people who had walked underneath the drone. In less than an hour of flying, he obtained network names and GPS coordinates for about 150 mobile devices.

He was also able to obtain usernames and passwords for Amazon, PayPal and Yahoo(YAHOF) accounts created for the purposes of our reporting so that we could verify the claims without stealing from passersby.

Collecting metadata, or the device IDs and network names, is probably not illegal, according to the Electronic Frontier Foundation. Intercepting usernames, passwords and credit card information with the intent of using them would likely violate wiretapping and identity theft laws.

Wilkinson, who developed the technology with Daniel Cuthbert at Sensepost Research Labs, says he is an ethical hacker. The purpose of this research is to raise awareness of the vulnerabilities of smart devices.

Installing the technology on drones creates a powerful threat because drones are mobile and often out of sight for pedestrians, enabling them to follow people undetected.

While most of the applications of this hack are creepy, it could also be used for law enforcement and public safety. During a riot, a drone could fly overhead and identify looters, for example.

Users can protect themselves by shutting off Wi-Fi connections and forcing their devices to ask before they join networks.

Technology is Making Seniors’ Lives Easier

Written By: Guest Contributor - Jul• 17•14

Seniors Technology Mobile Most senior citizens in the U.S. are already cell-phone-and-computer-savvy; nearly 80 percent of seniors 65 and older own a cell phone, while more than 60 percent own a computer or laptop. However, the use of other tech gadgets (i.e. smartphones and tablets) have yet to catch on in the “gray market,” as no more than 25 percent of U.S. seniors use either device.

With 10,000 Americans turning 65 daily—a trend expected to last for the next 17 years—the number of seniors using more tech devices should increase, as well. This bodes well for seniors, their families and friends and the digital market. For seniors not yet plugged in, making the transition from analog to digital is becoming simpler and is more practical now that tech and digital development experts are catering more to the needs of the boomer generation. Below are just a few ways that technology is benefiting seniors.

Apps for Everyday Use

There are other helpful apps, as well. One app—EyeReader—actually allows a person to use his or her smartphone as a magnifying glass for reading. Park’n'Forget is an app even younger generations might find useful, as it helps users remember where they parked their cars. It also has a timer on it to keep track of how long you’ve been parked, which is helpful when you’re in metered parking.

Apps for Safety

Start-up company Lively is a remote monitoring system for seniors that learns daily routines like taking pills, sticking to meal times and exercise. The sensors connect to a smartphone app, so family members can keep track of their loved one without compromising his or her privacy. Certain sensors are attached to items in the house, like pill boxes, the pantry or refrigerator and can even keep track of a user through a key fob that uses a Bluetooth low energy transmitter, in case one wanders past a certain range from home. Through the app on family members’ smartphones, they are alerted and updated on progress and activities.

What keeps seniors more independent is the ability to be mobile without their loved ones worrying about them falling or getting into an accident without them knowing. Devices like the GreatCall Splash are new, mobile-esque gadgets that allow a senior the freedom of leaving their home to shop or visit friends without worrying there could be an emergency and no way to call for help. While other press-a-button alert devices are still useful for the home, this device provides seniors security beyond their houses, giving them the ability to travel with only a button-click away from getting assistance from a 5Star Agent with the GreatCall Splash plan.

Support is Always Available, Just In Case

For many seniors, new technology can be so overwhelming that some people avoid it all together. In order for seniors to become more tech-savvy, new age companies have not only made devices more user-friendly, but many are offering easy “how-to” sites for seniors to help them learn new tech with step-by-step processes.

For example, the FaceTime app is a wonderful way for seniors to see and talk to faraway relatives through smartphones and iPads. How to even get to that app can be somewhat frustrating for some seniors. Dummies.com is really just a site that makes things simple for users. For instance, it has step-by-step directions for helping new users FaceTime using an iPad 2.

One reason many seniors avoid using technology is that, unaware of the options for protecting personal information and financial data, many of them are susceptible to identity theft. Big wireless corporations like Google, Apple and Samsung, as well as the four national service carriers have started a campaign to push the importance of data security for devices—with seniors specifically in mind. Lawmakers are lobbying for local and state governments to make “kill switches” mandatory on phones. The campaign is seeking laws where all phones manufactured in the U.S. after July 2015 be equipped with anti-theft features that include data wipe and lock capabilities, which can be reversed with the user’s password.

4 Ways to Back up Your Photos

Written By: Guest Contributor - Oct• 24•13

backup-options

How many photos have you taken in your life? Hundreds? Thousands? Some are probably torn and faded, stacked in a drawer. Others may not have ever made it to paper form and are taking up important space on your camera’s memory card.

The good news – you can easily free up space on your camera. You can transfer the pictures to your computer and then back them up so they won’t ever go missing.

The first step

Before you try any of these methods, transfer the photos from your digital camera (or smartphone if you’re tech-savvy) to your computer. Your camera should come with a USB cable that can connect it to the computer. After the connection, copy each photo into the “My Pictures” folder on your computer.

But what happens if your computer crashes? That’s where these four tips come in handy. You just need to do one – so pick whatever’s easiest for you.

1. USB flash drive

Head over to Walmart, Staples or any office supply store to pick up a USB flash drive. Nowadays, these little gadgets contain large amounts of storage space at a very affordable price – many under ten bucks!

Simply plug the flash drive into your computer and transfer your photos. This can be done the same way as the transfer to your computer from your digital camera – simply copy from the folder “My Pictures”, and paste into “Removable Disk” (i.e. your flash drive).

2. Social media

Are you on social media? Senior citizens are one of the fastest growing demographics on Facebook. Putting pictures on Facebook is not only a great way to share content with your family and friends, but it’s another method of backing up your pictures.

Easily post your photos on Facebook (or check out other websites, like Flickr), so that you can get to your images whenever you log in. By posting photos on the Internet, you’ll create a permanent backup.

3. E-mail

Shoot a few e-mails to yourself to back up your pictures. Simply attach the images and send to an e-mail address you plan on having forever.

Beware that many e-mail accounts limit the amount of data you can send – so send just a handful of pictures at a time. Stick all the messages in a folder and you’ll always have access to the images.

4. Cloud

Have you ever heard of “the cloud”? It’s a new tech term, so to put it simply – the cloud is a network of servers that allows you to do tasks, such as e-mail and store files, from any device with Internet connection (not just the bulky desktop at home).

So choose a cloud service, such as Dropbox, to store your pictures. Then, if your computer crashes or you want to look at the images from another location, they’ll be available to you!

Don’t wait to lose your pictures

Many people make the mistake of backing up their images after they were lost unexpectedly. Either they misplaced their camera, their computer crashed or another unforeseen misfortune occurred.

Don’t wait – back up your images now. Then, be sure to regularly back up your images so that you’ll always be able to look at them.
