Bacteria

If you’ve ever found room for dessert when you thought you were full, your gut bacteria might be to blame. Caltech scientists have shown that mice given antibiotics ate far more sugary snacks, hinting at a bacterial influence on overeating.

A new study has tugged photosynthesis research in an interesting new direction, with a team at Sweden’s Lund University demonstrating how carefully spaced mirrors can be used to trap light and supercharge its effects.

Probiotic bacteria can’t help improve gut health if they don’t survive to the intestines. Scientists have now kitted out good bugs with protective armor and backpacks loaded with molecules that can help them treat inflammatory bowel diseases (IBD).

Australia's Therapeutic Goods Administration has granted approval to a fecal transplant therapy designed to target a serious bacterial infection, marking the first time any regulatory body in the world has formally authorized this kind of microbiome therapy.

Scientists have demonstrated a new potential way to edit the genomes of bacteria in complex environments, by equipping viruses to hunt them down and insert the CRISPR gene-editing system.

Drugs given to the whole body can be too much of a shotgun approach, damaging cells that aren’t meant to be targeted. A new study has found that cloaking drugs inside red blood cells could help guide powerful but toxic antibiotics to target bacteria.

It's been a rough week for nose-pickers, with headlines loudly declaring "scary evidence" has been found linking Alzheimer's disease to a bit of finger-based nasal exploration. But what is the evidence behind this bold claim and is it really a problem?

There’s nothing like whipped cream to top off a dessert, but its high fat content comes with a side order of guilt. Now, researchers have found that saturated fat can be substituted with bacteria, to make whipped cream at two common consistencies.

Scientists at ETH Zurich looking to harness the cancer-fighting capabilities of bacteria have made an impressive advance, demonstrating how magnetic forms of the microorganisms can be propelled into tumors.

Urinary tract infections (UTIs) are common and treatable, but there can be complications, especially when the bacteria become drug resistant. Now, a new drug combo has shown promise in a Phase 3 clinical trial.

The rise of drug-resistant bacteria calls for new approaches to how doctors protect against bone infection after joint replacements, and a potent new form of bone cement is poised to take up the fight.

If you needed more motivation to brush your teeth, this could do the trick. Scientists have discovered that cavity-causing bacteria and fungi in saliva can team up to form “superorganisms” that can sprout limbs to crawl and even leap across teeth.
