1. Scientists Find Bacteria That Eats Plastic In a breakthrough study, scientists have identified a strain of bacteria that is capable of breaking down the plastic found in food packaging and other products. The bacteria, Ideonella sakaiensis 201-F6, was discovered living on plastic debris at a waste disposal site in Japan. The research team, which was led by Professor Shosuke Yoshida from the Kyoto Institute of Technology, found that I. sakaiensis 201-F6 had the ability to break down polyethylene terephthalate (PET) plastic. The bacteria use two enzymes to convert the PET into a more easily metabolized form, which then allows them to feed on it as a source of energy. This is the first time that a microorganism has been observed to have the ability to degrade PET plastic. The findings could have significant implications for helping to reduce the amount of plastic waste in the environment.
Surprising bacterium from Canadian lake shines new light on ancient photosynthesis
Sometimes an experiment doesn't go as planned. That's science. But a "failed" experiment or unexpected results can be the avenue to a discovery you could never anticipate. University of Waterloo Ph.D. student Jackson Tsuji had a poorly growing bacterial sample he wasn't ready to give up on, which ultimately led to a once-in-a-lifetime finding that could change how scientists view photosynthesis and its origins.
Tumor hypoxia modulates F. nucleatum infection of colorectal cancer cells | Research Communities by Springer Nature
The oral microbe, Fusobacterium nucleatum, is enriched in colorectal cancer and adversely impacts tumor progression. However, it is unclear how tumor hypoxia can modulate host cell response. Our study investigated host epigenomic and transcriptomic changes to infection under varying oxygen levels.
A sea of zombies! Viruses control the most abundant bacteria in the Ocean. | Research Communities by Springer Nature
How many bacterial cells are infected by viruses at any given time? We used fluorescence microscopy techniques to study virus infection in the most abundant marine bacterium - SAR11. We discovered many cells. Additionally, we discovered ribosome-deprived but virus-infected zombie cells.
Building a paper with Lego® | Research Communities by Springer Nature
The story behind our paper on the binding of a mucus-degrading bacterium to mucin, started with a presentation on O-glycosylation using Lego®. Never had I expected that this story would eventually end in the country where these plastic bricks were invented...
Life from a drop of rain: New research suggests rainwater helped form the first protocell walls | ScienceDaily
New research shows that rainwater could have helped create a meshy wall around protocells 3.8 billion years ago, a critical step in the transition from tiny beads of RNA to every bacterium, plant, animal, and human that ever lived.
Research team discovers 'impossible' unicellular organism
The origin of eukaryotes is considered one of the greatest enigmas in biology: according to current doctrine, two prokaryotes, a so-called Asgard archaeon and a bacterium, are believed to have merged. The bacterium is said to have developed into a mitochondrion. Thanks to its mitochondrion, this eukaryotic ancestor had enough energy available to develop into the more complex cells known today.
Tuberculosis under the sea: A marine sponge microbe provides insights into the bacterium's evolution
The surprising discovery of a bacterium in a marine sponge from the Great Barrier Reef with striking similarity to Mycobacterium tuberculosis, the pathogen responsible for tuberculosis (TB), could unlock and inform future TB research and treatment strategies. TB remains one of the world's deadliest infectious diseases, yet the origins of M. tuberculosis are still not fully understood.
Neolithic bones reveal isolated Yersinia pestis infections, not pandemics
Since the catastrophic pandemics of the Middle Ages, one disease has almost proverbially symbolized contagion and death: the plague. It is now known that the plague bacterium Yersinia pestis has been present in Central and Northern Europe for more than 5,000 years. However, it is still uncertain whether it also led to pandemics and mass deaths in its early forms.
