Common antioxidant could slow symptoms of aging in human skin

May 31, 2017

These cross-section images show three-dimensional human skin models made of living skin cells. Untreated model skin (left panel) shows a thinner dermis layer (black arrow) compared with model skin treated with the antioxidant methylene blue (right panel). A new study suggests that methylene blue could slow or reverse dermal thinning (a sign of aging) and a number of other symptoms of aging in human skin.

University of Maryland (UMD) researchers have found evidence that a common, inexpensive, and safe antioxidant chemical called methylene blue could slow the aging of human skin, based on tests in cultured human skin cells and simulated skin tissue.

“The effects we are seeing are not temporary. Methylene blue appears to make fundamental, long-term changes to skin cells,” said Kan Cao, senior author on the study and an associate… read more

Scientists at The Scripps Research Institute (TSRI) have discovered a way to structurally modify the antibiotic called vancomycin to make an already-powerful version of the antibiotic even more potent — an advance that could eliminate the threat of antibiotic-resistant infections for years to come.

“Doctors could use this modified form of vancomycin without fear of resistance emerging,” said Dale Boger, co-chair of TSRI’s Department of… read more

3D-printed ‘bionic skin’ could give robots and prosthetics the sense of touch

Could also be printed directly on human skin for pulse monitoring or as a human-machine interface --- imagine a computer mouse built into your fingertip

Engineering researchers at the University of Minnesota have developed a process for 3D-printing stretchable, flexible, and sensitive electronic sensory devices that could give robots or prosthetic hands — or even real skin — the ability to mechanically sense their environment.

One major use would be to give surgeons the ability to feel during minimally invasive surgeries instead of using cameras, or to increase the sensitivity of surgical… read more

Do robots creep you out?

Roboticists attempt to find out which presentation method presents the lowest barrier to communication

How do you make humanoid robots look least creepy? With increasing use of industrial (and soon, service robots), it’s a good question.

Researchers at the University of Koblenz-Landau, University of Wurzburg, and Arts Electronica Futurelab decided to find out with an experiment. They created a skit with a human actor and the Roboy robot, and presented scripted human-robot interactions (HRIs), using… read more

How Google’s ‘smart reply’ is getting smarter

A significant new hierarchical approach to machine intelligence
May 24, 2017

Can't make it

Last week, KurzweilAI reported that Google is rolling out an enhanced version of its “smart reply” machine-learning email software to “over 1 billion Android and iOS users of Gmail” — quoting Google CEO Sundar Pichai.

We noted that the new smart-reply version is now able to handle challenging sentences like “That interesting person at the cafe we like gave me a glance,” as Google research… read more

‘Wearable’ PET brain scanner enables studies of moving patients

Seeing more deeply into the brain in real time
May 23, 2017

Two scientists have developed a miniaturized positron emission tomography (PET) brain scanner that can be “worn” like a helmet.

The new Ambulatory Microdose Positron Emission Tomography (AMPET) scanner allows research subjects to stand and move around as the device scans, instead of having to lie completely still and be administered anesthesia — making it impossible to find associations between movement and brain activity.… read more

When AI improves human performance instead of taking over

May 22, 2017

The game results show that placing slightly “noisy” bots in a central location (high-degree nodes) improve human coordination by reducing same-color neighbor nodes. Square nodes show the bots and round nodes show human players; red edges show color conflicts, which are reduced with bot participation. (credit: Hirokazu Shirado and Nicholas A. Christakis/Nature)

It’s not about artificial intelligence (AI) taking over — it’s about AI improving human performance, a new study by Yale University researchers has shown.

“Much of the current conversation about artificial intelligence has to do with whether AI is a substitute for human beings. We believe the conversation should be about AI as a complement to human beings,” said Nicholas Christakis, Yale Universityread more

Princeton/Adobe technology will let you edit voices like text

Are you ready for fake audio (and maybe video) news?
May 19, 2017

fake audio ft

Technology developed by Princeton University computer scientists may do for audio recordings of the human voice what word processing software did for the written word and Adobe Photoshop did for images.

“VoCo” software, still in the research stage, makes it easy to add or replace a word in an audio recording of a human voice by simply editing a text transcript of the recording. New words… read more
