The Corner Ladder Folds In a Unique Way for Easy Storage (Video)


A beautiful wooden ladder that folds in a surprising way and fits into any old corner, perfect for Graham’s LifeEdited and other small spaces!

Paralyzed woman gets mind-controlled robot arm

In a clinical trial, Cathy Hutchinson, who has been paralyzed for more than 14 years, used the BrainGate system to mentally control a robotic arm and reach for a drink. The stroke that disconnected Cathy Hutchinson’s brain from her body has kept her silent and unable to move for more than 14 years. But science is starting to change all that.

New mother battling flesh-eating bacteria

An Upstate mom is in critical, but stable condition after her husband said she was diagnosed with a flesh-eating bacteria days after giving birth to twins.

Test teen football players for Alzheimer’s gene?

Should high school kids get a genetic test for the risk for Alzheimer’s disease before they’re allowed to play football? Two prominent scientists who study both Alzheimer’s and  the traumatic brain injury suffered by some football players raise that ethically charged question in an editorial out Wednesday in the journal Science Translational Medicine.

FDA Panel Endorses an Over-the-Counter HIV Test that Diagnoses in Just 20 Minutes

OraQuick HIV Test Already available for use inside doctor’s offices, Pennsylvania-based Orasure’s quick HIV test could soon be available to consumers for rapid testing in the home.
The test could be approved for sale later this year

It’s no cure, but it could mark a significant victory in the fight against HIV. A 17-member advisory panel for the Food and Drug Administration has endorsed an over-the-counter HIV test that would allow consumers to test themselves for the AIDS-causing virus in the privacy of their own homes in just 20 minutes. While the test is not perfect, the advisory panel has deemed that the benefits of regular in-home testing outweigh potential risks, and have recommended the FDA approve the test for over-the-counter sales.

Made by Bethlehem, Penn.,-based Orasure, the test uses an oral swab to return an HIV diagnosis in a matter of minutes. It is already available for use in clinical settings, and while it’s not quite as accurate as actual lab diagnostics it could help curb the spread of HIV by allowing for discrete, more regular testing. HIV and AIDS are largely spread via sexual contact from one partner to the other by those who do not realize they are infected with the virus.

If the advisory panel is right, the impact could be significant. Estimates indicate that roughly 240,000 people among the 1.2 million HIV carriers in the U.S. are unaware they are infected. That’s a full one-fifth. Education and other means of prevention have held the rate of new infections more or less steady at about 50,000 per year over the past 20 years in the U.S. The test has shown to be accurate in positively identifying HIV in trials 93 percent of the time. That means if everyone was testing regularly, Orasure’s test would still miss roughly 3,800 cases. But it would correctly diagnose 45,000 infected individuals. The FDA estimates that overall, the test could prevent 4,000 new cases each year.

Other at-home HIV tests can be purchased over the counter, but they still rely on consumers to take a blood sample and send it in to a lab for testing. Making HIV testing easy will encourage it as a regular practice, authorities hope, while also adding a layer of discretion and privacy around a sensitive topic. A survey showed that 84 percent of gay and bisexual men would test themselves more regularly if they could do so in their own home with an over-the-counter test (men who engage in sexual contact with other men are generally considered at higher risk for acquiring HIV).

The endorsement by the panel, however, does not spell approval for Orasure’s at-home 20-minute test. It still has to pass top-level FDA approval, a process that will take the panels findings into account. A final decision is expected later this year. The clinical version of the test reportedly retails to doctors for $17.50, but there’s no word on what consumer pricing might be.

ViviSat: An On-Call, Robotic Doctor for Ailing Satellites

Mission Extension Vehicle A ViviSat Mission Extension Vehicle (front, gold satellite) approaches an ailing geostationary satellite and prepares to dock. ViviSat

Aside from a couple particularly nasty collisions, dead satellites comprise the bulk of our planet’s space junk problem – as they die, get fried by radiation and become zombies, or are decommissioned, there’s nowhere for them to go. ViviSat aims to change that by servicing satellites where they are, pushing them into new orbits and allowing them to live longer.

ViviSat, which was founded last year, says it is in contract negotiations with satellite providers to work as a sort of on-call satellite doctor. When a satellite ends up in the wrong orbit or needs extra power to maintain it, ViviSat can launch a Mission Extension Vehicle to rendezvous with it.

It would launch on an ATK rocket, which could fit two at a time. Once it reaches orbit, it unfurls a solar array and sensors to track down the satellite it’s meant to assist. When it reaches its target, it uses proximity sensors and other tools to dock with the ailing orbiter, and then it could push it into a different orbit. It wouldn’t add fuel or take anything off the host satellite, which ViviSat says is a plus, because satellite builders may not want a third-party company tinkering with its massively expensive spy array or whatnot.

About 350 satellites orbit Earth in geostationary paths, and every year, about 25 of these run out of fuel, according to the company. Maybe 10 of those 25 are good candidates for an MEV servicing – not a huge number, but one that could still cut down on space waste.

ViviSat is a partnership between rocket launcher ATK and U.S. Space, which will manage the missions. At a conference this spring, ViviSat officials said government and private entities are interested in their services. The company just released this animation explaining how its MEV would work.

Electric Imp Will Connect Everything to the Internet

Hannah Board This board contains a rotary knob; two pushbuttons; an RGB light sensor; a temperature sensor; a 3-axis accelerometer; a hall sensor; an RGB LED; two servo outputs; 5 spare GPIOs; and an accessible I2C bus. So it could do a whole lot of things. Electric Imp

In my future house, I want a refrigerator that will tell me its contents via Wi-Fi, so I’ll be able to check whether I need extra butter when I’m at the market. I want a lamp that will turn on when it senses sunset, so I won’t have to adjust my automatic timers; I want a garden-watering system that will gauge whether my tomato plants are thirsty; and I want an outdoor rain/hail/snow sensor so I can make better weather spotter reports. The Internet of Things promises to bring me this world, and now there’s a cheap, customizable platform that could make it happen.

Electric Imp came out today, promising to connect any electronic device to the Internet and help you customize your life. The cards can be installed in almost any device, using circuit boards Imp sells, and apparently the company is also working with device manufacturers to start adding native Imp slots.

We’ve seen other prototypes connecting the Internet of Things, notably IBM’s Mote Runner, which can connect any hardware enabled with wireless sensors. But this one is unique because, as Gizmodo points out, it’s a universal system – connect anything you want, no back-end hardware or software required.

The software is pretty simple, using drag-and-drop graphics to set up commands, but it is also easily programmed, and users will be able to visit a hub where they can share tasks they’ve come up with. Within a couple minutes, the Electric Imp team set up a system that monitors a Christmas tree’s water supply and dims the lights when the water is getting low, meaning a dry tree. Watch it below.

A developer bundle is expected to be available late next month. Cards will cost $25 and circuit boards are between $10 and $25, depending on how many bells and whistles you want. Read more about the company here.
