Antibiotic-free method to protect animals from common infections

A herd of cattle or a flock of chickens may appear very bucolic, but they're actually ground zero for an ongoing arms race between scientists and disease-causing bacteria. Antibiotics have been a major weapon in the fight against animal infection, but they've also sparked evolutionary forces that create drug-resistant bacteria that render those very antibiotics ineffective, posing a major risk to animals and humans alike. Now a University of Wisconsin-Madison team is developing a method of fighting a major group of animal infections without antibiotics.Read More

Artificial photosynthesis breakthrough turns CO2 emissions into plastics and biofuel

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.

Maple syrup extract shows promise in fight against superbugs

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.

GermFalcon robot is made to sanitize airliners

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

Inkjet printers could produce paper sensors that identify dangerous food and water contaminants

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

Robobug: Scientists clad bacterium with graphene to make a working cytobot

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

More human-friendly antibacterial coating made from 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
