Technically the GE Vscan is not a cellphone, but it certainly resembles any old lamshell on the market today. Instead, the Vscan a pocket-sized ultrasound intended to reduce the amount of patient referrals (and thereby expenses) by making ultrasounds convenient enough to be performed in-house (and by house, we mean individual doctor's offices, not your house...yet).
I can't speak to the healthcare logistics at work, but I do know that moms love seeing photos of kids on their cellphones. Now if only this bad boy were linked to Picasa we'd really have something. [GE Reports]

I'll let the experts explain:

Using conventional lenses, it's not possible to focus light waves or sound waves to a spot size smaller than half the wavelength of the light. To get around these limitations, a lens must refract, or literally bend light backward. No naturally occurring materials have a negative index of refraction, but some materials carefully designed in the lab, called metamaterials, do.

Fang, a mechanical science professor at the University of Illinois at Urbana-Champaign, is using an array (pictured above) of specially shaped, water-filled cavities in a piece of aluminum, which supposedly work together to refract the sound by resonating in a particular way. It's all sort of unclear, and nobody has yet figured out how to get around that whole wavelength issue, but this could be the start of even crazier stealth technology, which is always fun to see—or not see. Get it? Because it's stealth. [Technology Review]

Teases for hologram technology are commonplace nowadays, but it is usually taken for granted that the projected images will provide no haptic feedback. Though the researchers have said little about integration with other projection systems, the possibility of a tactile hologram now doesn't seem totally out of the question. There's a major catch, though: the virtual objects won't provide much resistance or seem very "hard," because at high enough levels the aurally imperceptible ultrasound will destroy your eardrums. Even considering the limitations, my hope remains: that we may soon be able to (very delicately) slap people through a webcam. [BBC]

Tissue in the urethrovaginal space of the women who were no stranger to vaginal orgasms was, apparently, thicker than in that of the non-vaginal ones. This, says Janini, is evidence that women without any visible evidence of a G-spot cannot have a vaginal orgasm.

Beverly Whipple of Rutger's University School of Nursing in Newark, the team which coined the term G-Spot, is sceptical of Janini's findings. "It is an intriguing study, but it doesn't necessarily mean that women who don't experience orgasm don't have any tissue there." She reckons that the test would benefit from having women stimulate themselves first, and then repeating the ultrasound tests, as the area is believed to swell under physical pressure.

Janini is planning to continue his studies (of course he is) but says that women should not feel despair if they are unable to have vaginal orgasms. "One clear finding is that each woman is different," he says. "This is one reason why women are so interesting." And I thought it was our brains. [New Scientist]

We're not sure how well it works, but if we can get out of doing any form of exercise at all, then it's a winner in our books.

They've even got a demo video on the website narrated by a robot showing the plastic surgeon circling "problem areas" on the fatty patient. – Jason Chen

It's designed by Tobias Berneth, and as is the case with many of these concepts, there was no announcement about when or if it will be manufactured. But hey, Tobias, put this baby on a robot arm and teach that sucker how to use it, and we're home free. – Charlie White
