Storing data in everyday objects

The assembly and operating instructions are in the form of DNA. This is not the case with inanimate objects: anyone who wishes to print a 3-D object also requires a set of instructions. If they then choose to print the same item again years later, they need access to the original digital information. The item itself does not save the print instructions.

Researchers at ETH Zurich have now teamed up with an Israeli scientist to develop a means of storing extensive information on virtually any object. “With this method, we can integrate 3-D printing instructions into one object so that after decades or even centuries, these instructions can be downloaded directly from the object itself,” explains Robert Grass, professor at Department of Chemistry and Applied Life Sciences.

How hackers use smartphones to listen to your keyboard, study warns


Skilled hackers can use a smartphone to listen to what keys you are typing on your keyboard so they can gain access to personal information, a new study has warned.
Researchers from SMU's Darwin Deason Institute for Cybersecurity found that acoustic signals, or sound waves, produced when typing on a computer keyboard can successfully be picked up by a smartphone.
The sounds intercepted by the phone can then be processed, allowing a skilled hacker to decipher which keys were struck and what they were typing.

Hacker watches child through family security camera


A family in the US are warning others to be cautious after a hacker allegedly contacted their eight-year-old daughter through a home security camera. 
Ashley LeMay purchased the Ring brand in-home security camera as a way to keep an eye on her three children when she was working night shifts.
The camera was set up in her daughter Alyssa's bedroom at their Desoto County, Mississippi home.

Researchers produce first laser ultrasound images of humans


Technique may help remotely image and assess health of infants, burn victims, and accident survivors in hard-to-reach places.

For most people, getting an ultrasound is a relatively easy procedure: As a technician gently presses a probe against a patient’s skin, sound waves generated by the probe travel through the skin, bouncing off muscle, fat, and other soft tissues before reflecting back to the probe, which detects and translates the waves into an image of what lies beneath.

Conventional ultrasound doesn’t expose patients to harmful radiation as X-ray and CT scanners do, and it’s generally noninvasive. But it does require contact with a patient’s body, and as such, may be limiting in situations where clinicians might want to image patients who don’t tolerate the probe well, such as babies, burn victims, or other patients with sensitive skin. Furthermore, ultrasound probe contact induces significant image variability, which is a major challenge in modern ultrasound imaging.

Now, MIT engineers have come up with an alternative to conventional ultrasound that doesn’t require contact with the body to see inside a patient. The new laser ultrasound technique leverages an eye- and skin-safe laser system to remotely image the inside of a person. When trained on a patient’s skin, one laser remotely generates sound waves that bounce through the body. A second laser remotely detects the reflected waves, which researchers then translate into an image similar to conventional ultrasound.
