Smart contact lens

A new “smart” contact lens is designed and developed by a team from the Shenzhen Institutes of Advanced Technology (SIAT) at the Chinese Academy of Sciences. The prototype lens is made of a biocompatible hydrogel which is in turn composed of a polymer known as poly(2-hydroxyethyl methacrylate), or pHEMA for short.

The polymer’s nanostructure changes in reaction to moisture levels by changing color.

LED Skylights to Improve Windowless Offices

Sunshine keeps us humans happy and positive, most of the time anyway. So when you find yourself stuck indoors, in a dark and soulless space, your energy levels can drop quite dramatically, quite quickly. 

To counter such low feelings, as well as boost productivity, Mitsubishi created the Misola LED skylight. These LED panels look like skylights, so you can attach them to ceilings or walls, and are meant to simulate the effect of the Sun moving across the sky.


Technology to detect cancers with one drop of blood

A new, safe, and quick method for detecting 13 different kinds of cancers has been developed by Toshiba Corporation with a 99% accuracy rate and only requires one drop of blood for the process.

The method works by examining the types and concentration of microRNA molecules that are secreted into the bloodstream from the cancer cells.

The diagnosis method was developed together by the National Cancer Center Research Institute and Tokyo Medical University.

Mouthwash to kill harmful bacteria

According to the Health 2000 population survey, more than half of Finns aged 30 or over suffer from gum disease. 

Koite Health, which was founded by researchers from Aalto University and Helsinki University Hospital (HUS), is launching a method intended for home use that kills the streptococcus mutans bacteria and the bacteria that cause gingivitis. The treatment has been scientifically proven to reduce the markers indicating early gingivitis and plaque formation.

Transparent, flexible solar cells

Imagine a future in which solar cells are all around us — on windows and walls, cell phones, laptops, and more. A new flexible, transparent solar cell developed at MIT is bringing that future one step closer.

The device combines low-cost organic (carbon-containing) materials with electrodes of graphene, a flexible, transparent material made from inexpensive and abundant carbon sources.  The ability to use graphene instead of expensive brittle electrodes is making possible truly flexible, low-cost, transparent solar cells that can turn virtually any surface into a source of electric power.

Blended-wing airliner designs to slash fuel burn

Airbus is studying blended-wing airliner designs as a means to cut CO2 emissions by more than 20% and has already test flown a sub-scale model as part of its research efforts.

Blended-wing technology is of interest to the airframer because it is more efficient than standard tube-and-wing designs. The company is increasingly convinced that flying-wings are feasible because of the improvements in fly-by-wire and lightweight structural technology.

Bending Diamond

Diamond possess a range of extraordinary properties that make it an exceptional material. Among them is its exceptional mechanical stability and its reputation as one of the hardest known materials in the world. 

a team of Australian scientists have turned this idea of diamond’s indisputable hardness on its head; having discovered that diamond can actually be bent and deformed … that is, on the nanoscale.

Robots in the fight

Doctors in the US have been using a telehealth machine to treat the first person in the country admitted to hospital with 2019-nCoV. The man is currently being held in a specially designed two-bed isolated area at Providence Regional Medical Center in Washington.

The room was set up five years ago during the Ebola crisis, but this is the first time it’s ever been used. It is away from other units at the hospital and even has a separate air filter. There is only one entry point for the unit which is guarded by security officers and visitors are required to wear full-body protection including a controlled air purifying respirator helmet.

Using a robot equipped with a camera, microphone and stethoscope, the patient has been able to consult with clinicians without coming into direct contact with them. The nursing staff in the room move the robot around so they can see the patient in the screen and talk to him.

This isn’t the only robot that’s being used to interact with quarantined people. A hotel in Hangzhou is being used to isolate more than 300 people suspected to have the virus, and has been using a robot to deliver food to their bedrooms.

Patch to Automatically Deliver Insulin

A combination of a wearable glucometer and insulin pump, connected via a smart control mechanism, can function as an artificial pancreas. But researchers at University of California Los Angeles, University of North Carolina, and MIT have created and now tested an electronics-free wearable patch that automatically releases insulin based on rising glucose levels.
