New electronic stethoscope and app diagnose lung conditions

February 24, 2016

Based on an analysis of the characteristics of respiratory sounds, the Respiratory Sounds Visualizer app generates this diagnostic chart. The total area in red represents the overall volume of sound, and the proportion of red around each line from the center to each vertex represents the proportion of the overall sound that each respiratory sound contributes. (credit: Shinichiro Ohshimo et al./Annals of Internal Medicine)

The traditional stethoscope has just been superseded by an electronic stethoscope and an app called Respiratory Sounds Visualizer, which can automatically classify lung sounds into five common diagnostic categories.* The system was developed by three physician researchers at Hiroshima University and Fukushima Medical University in collaboration with Pioneer Corporation.

The respiratory specialist doctors recorded and classified lung sounds of 878 patients, then turned these… read more

Ever just want to wave a magic wand instead of dealing with a complex home network setup?

Well, Dartmouth College computer science professor David Kotz has figured out how to do just that. Called “Wanda,” it’s a small rod that makes it simple to link a new device (such as a blood-pressure meter or smartphone) to a WiFi network by just pointing the rod at the device.… read more

Cancer cells in 3D

What researchers miss on glass slides
February 22, 2016


Cancer cells don’t live on glass slides. Yet the vast majority of images related to cancer biology come from the cells being photographed on flat, two-dimensional surfaces — images sometimes used to draw conclusions about the behavior of cells that normally reside in a more complex environment.

Now a new high-resolution microscope, presented (open access) February 22 in Developmental Cell, makes it possible to visualize cancer cells in 3D and… read more

Real or computer-generated: can you tell the difference?

Training helps humans tell them apart ... but soon, only computers will know what's real or not
February 22, 2016

A Dartmouth College study shows that people find it increasingly difficult to distinguish between computer-generated images and real photos, but that a small amount of training greatly improves their accuracy. (credit: Dartmouth College)

As computer-generated characters become increasingly photorealistic, people are finding it harder to distinguish between real and computer-generated, a Dartmouth College-led study has found.

This has introduced complex forensic and legal issues*, such as how to distinguish between computer-generated and photographic images of child pornography, says Hany Farid, a professor of computer science, pioneering researcher in digital forensics at Dartmouth, and senior author of a paper… read more

Could ‘smart skin’ made of recyclable materials transform medicine and robotics?

How to create sophisticated sensors in your kitchen with aluminum foil, scotch tape, sticky-notes, napkins, and sponges and a $25 computer
February 19, 2016

smart skin disposable pH sensor-ft

Here’s a challenge: using only low-cost materials available in your house (such as aluminum foil, pencil, scotch tape, sticky-notes, napkins, and sponges), build sensitive sensors (“smart skin”) for detecting temperature, humidity, pH, pressure, touch, flow, motion, and proximity (at a distance of 13 cm). Your sensors must show reliable and consistent results and be capable of connecting to low-cost, tiny computers such as Arduino and Raspberry Pi devices.

A virtual “intelligent coaching space” (ICSPACE) developed by Cluster of Excellence Cognitive Interaction Technology (CITEC) at Bielefeld University in Germany is assisting patients with physical rehabilitation and helping athletes improve their performance with sports exercises.

The user is 3D-scanned in advance and used to create an avatar. Participants wear 3D stereoscopic glasses, which create the impression of working out in a gym with a coach. Reflective markers… read more

New method enables discovery of 3D structures for molecules important to medicine

February 19, 2016

protein crystals ft

Researchers have overcome a long-standing technical barrier to imaging 3D structures of thousands of molecules important to medicine and biology.

The 3D structures of many protein molecules have been discovered using a technique called X-ray crystallography, but the method relies on scientists being able to produce highly ordered crystals containing the protein molecules in a regular arrangement. When X-rays are shone on highly ordered crystals, the X-rays scatter… read more

Astronomers have analyzed the atmosphere of a “super-Earth” exoplanet for the first time, according to The Hubble Space Telescope project, an international cooperation between ESA and NASA. Result: it’s mostly hydrogen and helium.

The data gathered with the NASA/ESA Hubble Space Telescope and new analysis techniques also revealed that exoplanet 55 Cancri e has a dry atmosphere… read more

‘Eternal 5D’ data storage could reliably record the history of humankind

Digital documents stored in nanostructured dots in fused quartz crystal for billions of years could survive the end of the human race

bible on disc

Scientists at the University of Southampton Optoelectronics Research Centre (ORC) have developed the first digital data storage system capable of creating archives that can survive for billions of years.

Using nanostructured glass, the system has 360 TB per disc capacity, thermal stability up to 1,000°C, and virtually unlimited lifetime at room temperature (or 13.8 billion years at 190°C ).

As a “highly stable and safe form… read more

Less-distracting haptic feedback could make car navigation safer than GPS audio and displays

Do you find your GPS voice and display distracting? Does your driving sometimes suffer?

Human factors/ergonomics researchers at General Motors and an affiliate have performed a study using a new turn-by-turn automotive navigation system that uses haptic cues (vibrations) to the temples to communicate information to drivers on coming turns (which direction and when to turn), instead of distracting voice prompts or video displays.

They modified a prototype smart-glasses device with motors in two actuators (on the right and left side of the… read more

3D-printing a new lifelike liver tissue for drug screening

Could let pharmaceutical companies quickly do pilot studies on new drugs
February 15, 2016


University of California, San Diego researchers have 3D-printed a tissue that closely mimics the human liver’s sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling and could help pharmaceutical companies save time and money when developing new drugs, according to the researchers.

The liver plays a critical role in how the body metabolizes drugs and produces key proteins, so liver… read more

pilot brain patterns

You can learn how to improve your novice pilot skills by having your brain zapped with recorded brain patterns of experienced pilots via transcranial direct current stimulation (tDCS), according to researchers at HRL Laboratories.

“We measured the brain activity patterns of six commercial and military pilots, and then transmitted these patterns into novice subjects as they learned to pilot an airplane in a realistic flight… read more

Clearing out the clutter: ‘senolytic’ drugs improve vascular health in mice

Mayo Clinic researchers have demonstrated the first study in which repeated treatments to remove senescent cells (cells that stop dividing due to age or stress) in mice improve age-related vascular conditions — and may possibly reduce cardiovascular disease and death.

The researchers intermittently gave the mice a cocktail of two senolytic drugs (ones that selectively induce cell death): dasatinib (a cancer drug, trade… read more
