Technology’s dark side: A 3D print of your head is all it takes to open your phone
The facial recognition technology of your smartphone is going to betray your secrets to the first 3D-printed replica of your head shown to it. This security flaw applies to all smartphones, especially the Android-powered ones. Cyber security writer Thomas Brewster tested the latest models of Android phones that feature facial recognition. He used a 3D-printed replica of […]

Your next data storage device could be as small… as a molecule
The seemingly unending desire for increasing amounts of space to store even more electronic data has led Swiss researchers to look for answers at the molecular level. They came up with a data storage network made up of molecules, each of which could store a bit of data. The concept takes advantage of the ability of […]

Scientists develop revolutionary material that can shape-shift
We are getting one step closer toward the liquid metal “polyalloy” that allowed the T-1000 killer robot to change its appearance in Terminator 2. Recently, a Texas-based research team unveiled a new polymer made from liquid crystal and plastic that can shape-shift into complex forms. At room temperature, the material will assume the physical form […]

3D printing is key for the successful colonization of Mars
When humans finally take over Mars, it will be with the help of 3D printing technology. Additive manufacturing will provide invaluable services during the colonization of the Red Planet, including the all-important role of shielding colonists from deadly cosmic radiation. Traditional manufacturing lines are limited to building a single product. A 3D printer, on the other hand, can change the […]

“2D” materials the next big thing in computing
Three-dimensional materials have finally reached the peak of their performance. Electronics built out of these legacy semiconductors can no longer be made any smaller, stronger, and more efficient at the same time. So researchers are working on 2D nanomaterial replacements that can meet these insatiable demands. The conventional 3D semiconductors enjoyed a good run that lasted for 60 […]

Researchers develop a system that levitates objects using only ultrasonic waves
Have you ever imagined moving a small object across the room by just pointing at the direction you need it to go? German researchers have created a device called LeviCursor that can accomplish that magical task of levitating items with invisible ultrasonic waves. LeviCursor is the the latest step towards realizing a dream long cherished by information technology (IT) […]

New flexible sensor can map blood-oxygen levels over large areas of skin
Oxygen is an important ingredient in the body’s natural healing process. To accurately determine if the blood has enough of this vital molecule, researchers have designed a handy oximeter to help in treating injuries. The new blood-oxygen sensor is a flexible device that can scan considerable swathes of skin, tissue, and even organs. By analyzing the […]

Researchers find a powerful fuel catalyst – in Jell-O
The ingredient responsible for Jell-O’s famous jiggling can be used to make an incredibly cost-effective catalyst for producing hydrogen fuel. Researchers claimed that their gelatin-derived compound can match the performance of its much more expensive platinum-based equivalent. The new water-splitting material is made up of extremely thin sheets of metal carbide, an inexpensive earth element found nearly everywhere. Gelatin is […]

New nanomaterial could lead to a highly sensitive biomolecule sensor or a more efficient solar cell
Visible and infrared light will not escape from the new plasmonic absorber developed by Singaporean researchers. Called Ag-Sb2S3, the silver-based nanomaterial can transfer all of the light it captures to photovoltaic cells for producing energy, or to sensitive detectors that can pick out minute biomolecules floating in the air. Despite being made from expensive silver, Ag-Sb2S3 enjoys low […]

New class of strong biocompatible adhesives made from silk
Silk is usually used to make beautiful yet durable clothes and fabrics. Korean researchers demonstrated that the ancient material can be used as an effective yet comfortable bio-compatible adhesive for epidermal electronics. These skin-attached electronics need an “interface” that connects the sensor and the biological surface. The glue must be strong enough to keep the sensor in place […]
