Researchers have developed an artificial photosynthesis technology that could be a win/win...

Scientists at the Lawrence Berkeley National Laboratory and the University of California, Berkeley have created a hybrid system of bacteria and semiconducting nanowires that mimics photosynthesis. According to the researchers, their versatile, high-yield system can take water, sunlight and carbon dioxide and turn them into the building blocks of biodegradable plastics, pharmaceutical drugs and even biofuel.  Read More

Scientists have produced a maple syrup extract that bolsters the ability of antibiotics to...

Researchers at Canada's McGill University have uncovered what could be a pretty sweet way of warding off bacteria. The scientists developed a concentrated extract of maple syrup and combined it with antibiotics, finding that it heightened bacteria's vulnerability, suggesting it could prove an effective way of lowering dosages required to treat infections and help to hamper the evolution of drug-resistant superbugs.  Read More

A GermFalcon prototype makes its way down an airliner's aisle (Photo: GermFalcon)

Airliner cabins can get pretty germy. They're packed full of people from all over the world, who spend hours doing things like coughing, sneezing and touching surfaces with their grubby li'l hands. It was with this in mind that Arthur Kreitenberg and his son Mo created the GermFalcon. It's a robot that kills germs on planes, using ultraviolet light.  Read More

Ordinary inkjet printers can be given a special cartridge containing DNA-based bio-ink tha...

Sensors that identify infectious disease and food contaminants may soon be printed on paper using ordinary office inkjet printers. Researchers at McMaster University have developed a prototype that could lead to a commercial product in the next few years which helps doctors and scientists in the field quickly detect certain types of cancer or bacterial and respiratory infections or monitor toxin levels in water.  Read More

Patients can snap a shot of the film with their smartphone camera and send it off to a med...

Researchers at Florida Atlantic University (FAU) have created a cheap and simple biosensing platform that is able to detect the presence of various types of harmful bacteria and viruses in a single drop of blood. When used in conjunction with a smartphone, the system offers the potential of diagnosing diseases in remote locations from anywhere in the world.  Read More

Researchers have created a nanoscale biomicrorobot (or 'cytobot') that responds electrical...

By cladding a living cell with graphene quantum dots, researchers at the University of Illinois at Chicago (UIC) claim to have created a nanoscale biomicrorobot (or cytobot) that responds electrically to changes in its environment. This work promises to lay the foundations for future generations of bio-derived nanobots, biomicrorobotic-mechanisms, and micromechanical actuation for a wide range of applications.  Read More

Research team member Dr. Katarzyna Wybranska, with a wound dressing treated with the gold ...

We've been hearing a lot about the antibacterial qualities of silver, with silver nanoparticles finding use in everything from water filters to food packaging. Unfortunately, there are also concerns about the toxicity of those particles, particularly when they enter our bodies. Now, however, Polish scientists have developed what they claim is a safer alternative – an antibacterial coating that kills microbes using gold.  Read More

Bacterial biofilm formation on the right side of medical tubing is visible after being sta...

Whenever foreign objects such as catheters, implants or other devices are placed within the human body, there's a danger that bacterial colonies known as biofilms could collect on them, leading to infections. Now, however, scientists at Harvard University's Wyss Institute have created a material that's too slippery for those biofilms to cling onto. It works by continuously releasing oil.  Read More

New research gives hope that diabetics may one day be able to take a daily probiotic pill ...

Researchers at Cornell University have successfully treated diabetic rats by engineering a strain of lactobacillus, a rod-shaped bacteria common in the human gut, resulting in up to 30 percent lower blood glucose levels. The technology could pave the way for a new treatment for both type 1 and type 2 diabetes that could one day see managing diabetes be as easy as taking a daily probiotic pill..  Read More

A section of a 2.3 billion-year-old rock bearing fossils (the dark areas) that are essenti...

Claimed to be the greatest lack of evolution ever discovered, a deep-sea microorganism – sulfur bacteria – recently uncovered by an international group of scientists is reported not to have evolved for more than 2 billion years. Despite it appearing to be an aberration in nature, researchers say that the microscopic creature’s unchanging nature actually supports Charles Darwin’s theory of evolution.  Read More
