What would you do if you saw an ice cream truck with a giant boob--nipple and all--on its roof?

You'd probably do a double-take. Then, tell your kids to stay away because they can't buy ice cream from it. It's not an ice cream truck, after all. It's The Milk Truck, an on-call mobile breastfeeding vehicle that performance artist and mom Jill Miller would like to turn into a reality.

Miller--a faculty member at the School of Art at Pittsburgh's Carnegie Mellon University--is looking to raise $10,000 in funding through pledge site Kickstarter. If the breastfeeding crusader succeeds, nursing moms in the Pittsburgh area (and eventually beyond, Miller hopes) will never have to worry about finding a private spot to pump or nurse again.

"There's a reason for making The Milk Truck," Miller writes on her Web site. "To create a mobile breastfeeding unit that allows mothers to feed their babies in places where they have been discouraged: restaurants, shopping malls, public spaces, etc. Babies should be able to eat anywhere. And everywhere." … Read more

Researchers at the Massachusetts Institute of Technology are working on an inexpensive way to use smartphones to quickly detect early-stage cataracts, the clouding of the eye lens that is the leading cause of blindness worldwide.

Developed by Media Lab Camera Culture group director Ramesh Raskar and colleagues, the Catra system is made of off-the-shelf components. Users peer through an eyepiece that slides onto a smartphone or other smart device like an iPod Touch, and they view lines displayed on the screen.

When the lines appear cloudy, the user presses a button. In that way, the device scans the lens of the eye to create a map of the cloudy areas, which are produced by proteins clumping together.

Identifying the position, size, shape, and density of the clouds, Catra can produce a diagnosis of cataracts in minutes. Check out the promo video below.

The idea is that Catra could be used in the developing world, where few have access to the expensive slit lamps and clinicians used to diagnose the disorder. That could lead to earlier detection of cataracts and better treatment results following surgery. … Read more

We all have that story about running into someone in the unlikeliest of places. The freshman year roommate from Chicago stumbles into your path in a crosswalk in London. The distant cousin nearly crashes into you on a mountain bike trail in Moab. The ex-lover you want to forget is sitting next to your table as you dine with a new lover you don't want to forget. Et cetera.

Given the times our paths actually do cross, there must be hundreds, perhaps thousands, of times when we just miss each other. And a professor at Ohio State University thinks … Read more

A new saliva test developed by geneticists at the University of California, Los Angeles, reveals a person's age within five years, a finding that could have many applications in medicine, at crime scenes, and more.

"With just a saliva sample, we can accurately predict a person's age without knowing anything else about them," says principal investigator Dr. Eric Vilain, a professor of human genetics, pediatrics and urology, in a UCLA news release.

The team's research, published online this week in the Public Library of Science's PLoS One journal, focuses on methylation, a process by … Read more

The notion of erasing memories associated with painful or harmful pasts is not a new one. But it has remained just that: a notion.

Now scientists in Israel say they have devised a method to erase memories that trigger cravings in rats addicted to cocaine--a method that works so well it actually results in rats ignoring the place where they had been scoring the drug.

"Memories can trigger a desire for the drug, including memories of the drug itself, the needle, or the environment in which the drug was consumed," says Hebrew University researcher Rami Yaka. "This research indicates the possibility of erasing these memories in a way that will allow addicts to cancel the associations they have in their minds regarding the drug."

The team worked with a small protein called ZIP, which has been found in other studies in recent years to erase memories and even, as a result, inhibit learning processes.

After giving the rats cocaine in a designated spot in their pens for a few weeks, the team injected ZIP into the nucleus accumbens, a brain region known to control pleasure, reward, fear, and more, and then returned the rats to their pens. The rats proceeded to ignore the location they had only recently sought out, suggesting they no longer remembered either the place, the effect of the drug, or perhaps both.

Yaka, who will present his team's findings at the Facing Tomorrow 2011 conference in Jerusalem next week, sees possibilities not just for drug addicts but also those suffering from posttraumatic stress disorder and other psychological conditions.

Of course, it remains unclear whether the protein erases selective memories associated with drugs, or if other pleasure-and-reward memories are also affected. Will one also forget the sweetness of chocolate? The ecstasies of copulation? The kiss of a gentle summer's breeze?

If so, will it be worth it?… Read more

The tricorder, that handheld geological, biological, and meteorological device of general awesomeness from the Star Trek universe, has spawned several real-life iterations boasting such uses as the detection of ulcers and deadly gases.

So in May, the X Prize Foundation announced that, alongside Qualcomm, it would award a $10 million Tricorder X Prize to the person who develops a mobile device that can diagnose a broad range of common health ailments as well as--or better than--a panel of board-certified physicians.

A team at Oregon State University in Corvallis is now one step closer to what remains a pretty tall order.… Read more

In the words of William Gibson, the future is already here. It may be barely Google-able in an obscure scientific publication, but it has profound implications for the future of implantable medical (and other) sensors.

That future is a nanoscale device that manages to transmit data wirelessly up to 30 feet and operate without a battery, instead harvesting energy from the environment via such sources as the pulse of a blood vessel or the gust of a breeze.

"It is entirely possible to drive these devices by scavenging energy from sources in the environment such as gentle airflow, vibration, … Read more

With millions of implantable medical devices in the U.S. alone, and some 300,000 more people receiving them worldwide every year, the need to protect these wireless devices from being hacked is increasingly urgent.

Wearers might soon be better protected, thanks to new work out of MIT and the University of Massachusetts-Amherst, so long as they don't mind walking around in invisible shields.

The system the research team will be proposing at the Association for Computing Machinery's Sigcomm conference in Toronto this August uses a jamming transmitter small enough to be worn as a watch or necklace.

The device would essentially be authorized to access the implant and send encrypted instructions to the transmitter (the team calls this the "shield"), which would in turn decode the encryption and relay the instructions to the implant.

Using a device that is separate from the medical implant is key for a few reasons: it allows for post-encryption in devices that are already implanted; it enables authorized emergency responders to simply remove the patient's shield in the event of emergencies; and it doesn't require the size of the implants to increase to accommodate and power the shield.

The new system expands on a technique recently developed at Stanford University that allows for sending and receiving signals in the same frequency band. In typical wireless technology, using the same frequency band interferes with the signal, but by employing three antennas positioned precise distances apart, one band can now be used.… Read more

Many of us know at least one person who has a hearing aid that sits on a shelf somewhere, collecting dust. The usual complaint: The thing just doesn't work right.

A professor at the University of Essex in the U.K. says these aren't just excuses, but legitimate complaints. "Today's hearing aids don't help to separate sounds--they just amplify them," said Ray Meddis, who has led work on a new kind of hearing aid. "They often make everything too noisy for the wearer, especially in social situations like parties, and some wearers still can't make out what people are saying to them. They find the whole experience so uncomfortable that they end up taking their hearing aids out," Meddis said in a statement released today.

Meddis and his team at Essex have been working on a new kind of aid they say could revolutionize what is now an antiquated approach to treating hearing impairments. The key, they say, is to use unique computer models (what they call "hearing dummies") that treat the root causes, not just the symptoms, of the user's unique condition.

"In the same way that a tailor's dummy is used to measure and fit a garment for a particular person, our software dummy is used to gauge a patient's hearing requirements so that their hearing aid can then be programmed to suit their needs," Meddis said.… Read more
