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 […]

Steel found to have “fingerprints” which could help researchers detect tampered parts
It turns out that steel possesses the magnetic equivalent of a “fingerprint” that changes from sample to sample. Even products drawn from the same batch of raw materials and made using the exact same techniques will display different and unique magnetic fingerprints. Researchers believe they could use this property to identify and authenticate the steel items. Officials who enforce […]

Novel smart material can respond dynamically to its environment
Researchers from Brown University have built a new smart material that combines the strength of graphene oxide and the oil-repelling ability of an alginate hydrogel. Not only is the material is stronger than pure alginate — the base material for many biomedical devices — but it can also change its attributes according to the state of its environment. Alginate is […]

MIT engineers have created a “Sun in a box” which stores renewable energy to be used on demand
The new renewable energy storage method devised by researchers at the Massachusetts Institute of Technology has a proper technical name. But many call it “Sun in a box” because of its conceptual resemblance to the giant ball in the sky that provides the Earth with seemingly unlimited amounts of energy. Just like the Sun, the Thermal Energy Grid […]

New camera helps people “see” the invisible using high-frequency waves
Delaware-based researchers have come up with the next best thing to having Superman’s X-ray vision. Their new device can produce millimeter waves that penetrate opaque solids and reveal the objects obscured by the obstacle, much like how an X-ray machine shows the internals of the body. Millimeter waves occupy a band of frequencies ranging from 30 to 300 […]

Researchers build a robotic platform to observe the effects of neonicotinoids on bee behavior
A video camera-controlling robot was used to record the negative effects of neonicotinoids on bumblebees. The Harvard-designed machine was able to record and show the disruptive effects of the pesticides on the way the bees behaved, interacted with other members of their nest, and regulated their body temperature. Bees are in serious danger from widely used neonicotinoid pesticides. […]

Novel research raises prospects for large-scale production of algae-derived starch
Japanese researchers found the natural means by which a species of algae regulates its starch production. They believe this biological mechanism can be used to increase the starch content of algae, which would make it much more efficient and profitable to cultivate the tiny plant on an agricultural scale. Starch is not just the natural […]
