Bacteria

We've already heard about experimental self-healing concrete, that can repair cracks within itself. Now, scientists have gone a step further, utilizing bacteria to create building materials that can be grown on-site – and that regenerate when broken.

One of humanity’s biggest threats is also the smallest – bacteria. But now, researchers at RMIT in Australia have found a new method for killing these superbugs that they can’t resist – magnetic nanoparticles that physically tear them to shreds.

The autoimmune disorder celiac disease is thought to result largely from genetic predisposition, but environmental factors also play a part. Now, researchers have found evidence that exposure to certain bacteria may be one of these external factors.

Polysporin may be in for some serious competition, as Swedish scientists have created a healing gel that not only kills antibiotic-resistant bacteria, but also reduces inflammation within wounds. It could someday replace antibiotic-based medications.

Currently, in order to determine if someone has a urinary tract infection, their urine sample has to be sent off to a lab – it takes days to get results. Now, scientists have created a smartphone-enabled system that works in less than 25 minutes.

INTEGRATE is a newly-developed version of CRISPR that edits genes more gently. It uses “jumping genes” that insert large sequences of DNA without breaking the strands, and now scientists have imaged the mechanism at work for the first time.

Much like the gut, skin and mouth, our respiratory system is home to its own unique microbial population. Intriguing new research has now found a link between specific bacterial populations in the upper airways and the severity of asthma symptoms.

Some bacteria use tiny syringes to inject toxins into their host’s cells. Now, researchers from the Max Planck Institute have found a way to use this to our advantage, by swapping out these toxins for other chemicals, like drugs.

Researchers at Rice University have developed a new method to kill emerging superbugs, using molecular “drills” to pierce their cell walls. The same technique has also been shown to work on cancer cells.

One of the most alarmingly plausible (and overlooked) doomsday scenarios is the rise of the superbug, bacteria that are resistant to antibiotics. But now, scientists have found a new potential treatment – and it was hiding in our skin the whole time.

Bacteria tend to build colonies behind barriers known as biofilms, which are hard for antibiotics to penetrate. Now, researchers at the Queensland University of Technology (QUT) have developed a hybrid antibiotic that can punch through some biofilms.

Researchers have created bacteria that can effectively eat air. By carefully directing the evolution of E. coli in the lab, the team managed to wean them off their preferred diet of sugar, and make the switch to carbon dioxide in the air around them.
