Lasers and terahertz waves combined in camera that sees 'unseen' detail February, 2020
A team of physicists has successfully developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation.
Is it hemp or marijuana? New scanner gives instant answer February, 2020
Hemp is technically legal in Texas, but proving that hemp is not marijuana can be a hurdle, requiring testing in a licensed laboratory. Now, a team of researchers have created a 'hemp scanner' that could easily fit in a police cruiser and distinguish hemp and marijuana instantly, without damaging any of the product.
Experimental fingerprint test can distinguish between those who have taken or handled cocaine February, 2020
An experimental fingerprint detection approach can identify traces of cocaine on human skin, even after someone has washed their hands -- and the test is also smart enough to tell whether an individual has actually consumed the class A drug, or simply handled it.
Residues in fingerprints hold clues to their age January, 2020
Police have long relied on the unique whorls, loops or arches encoded in fingerprints to identify suspects. However, they have no way to tell how long ago those prints were left behind -- information that could be crucial to a case. A preliminary new study suggests that could change. Researchers report that they could link […]
Low power metal detector senses magnetic fingerprints January, 2020
Recent studies have shown metallic objects have their own magnetic fingerprints based on size, shape and physical composition. Scientists look to leverage these observations to potentially create a smaller and cheaper system that is just as effective as their larger counterparts.
Improving efficiency, effectiveness of security X-ray technology December, 2019
The smuggling of contraband is a threat in airport security and risks have increased in modern times with the uptick in parcel delivery, but security inspection methods have not seen any significant improvements. Researchers propose a technique for efficient detection of contraband items. Typically, airport security uses X-ray imaging to quickly scan baggage, but this […]
Scientists identify harmful bacteria based on its DNA at a very low cost December, 2019
Currently, the detection of food poison outbreaks caused by bacteria takes a long time and is expensive, but this does not have to be the case in the future. Researchers have found a method for the precise identification of bacteria in just a few hours on a mobile-phone-sized device that costs about 200 times less […]
Tiny devices made of DNA detect cancer with fewer false alarms November, 2019
A new cancer-detecting tool uses tiny circuits made of DNA to identify cancer cells by the molecular signature on their surface. The circuits work by attaching to the outside of a cell and analyzing it for proteins that are more abundant on some cell types than others. The devices distinguish cell types with higher specificity […]
Fingerprint test can distinguish between those who have taken or handled heroin November, 2019
A state-of-the-art fingerprint detection technology can identify traces of heroin on human skin, even after someone has washed their hands -- and it is also smart enough to tell whether an individual has used the drug or shaken hands with someone who has handled it.
Quantum chip 1,000 times smaller than current setups October, 2019
Researchers have developed a quantum communication chip that is 1,000 times smaller than current quantum setups, but offers the same superior security quantum technology is known for.
