Sharpest images of living bacteria reveal unexpected membrane structure

The images are so clear that scientists can see proteins on a bacterium’s outer membrane.

Using a microscopy technique that pulls back the curtain on the nanoscale world, researchers have generated the sharpest images of live bacteria ever taken. The high-resolution snaps reveal a patchwork of proteins that make up the outer membrane and, potentially, give scientists a new way to attack the organisms.

In a study published Monday in the journal Proceedings of the National Academy of Sciences, researchers from the US and UK provide images of the rod-shaped bacterium Escherichia Coli, which is commonly found in our gastrointestinal tracts and helps digest food. It’s a mostly harmless citizen of our guts, but certain E. Coli strains can cause severe illness. In recent years, scientists have shown that these strains are becoming more resistant to antibiotics.

The bacteria are, of course, incredibly tiny. About 150 to 300 individual bacteria could probably fit head-to-toe across the period at the end of this sentence. While regular microscopes can see the bacteria as clumps of rods scattered all across a glass slide, they don’t give us a good idea of the structure of a bacterium’s body and the outer membrane that protects it from our drugs.

«The outer membrane is a formidable barrier against antibiotics and is an important factor in making infectious bacteria resistant to medical treatment,» Bart Hoogenboom, a nanotechnologist at University College London and co-author on the paper, said in a press release. Hoogenboom and his team wanted to take a much closer look and turned to «atomic force microscopy» to study the membrane in greater detail.

Atomic Force Microscopy, or AFM, is a powerful technique to study objects that are just nanometers in length. (A nanometer is a millionth of a millimeter.) Hooked up to a computer, the device can study the surface of tiny, tiny objects by running a fine-tipped probe, just a few nanometers wide, across the surface. The probe moves along the object — whether it’s a microbe, a piece of bone or another nanomaterial — and can sense the undulations present. You can imagine it kind of like a turntable stylus, moving along the grooves of a vinyl record. Totally different process but similar concept.

When the team ran the AFM probe over the surface of a living E. Coli bacterium, they discovered it was a mosaic of proteins. Most areas of the outer membrane were covered in mostly immobile proteins, but there were also islands that lacked any protein at all and were instead full of sugary lipid molecules.

«This suggests that the barrier may not be equally hard to breach or stretch all over the bacterium, but may have stronger and weaker spots that can also be targeted by antibiotics,» Hoogenboom said.

Outer membranes are present on what’s known as «gram-negative» bacteria, like E coli, and not gram-positive bacteria, like Staphylococcus. The «gram» doesn’t refer to weight, but a specific test designed to quickly differentiate bacteria based on their cell walls. Notably, gram-negative bacteria have a more impenetrable cell wall, which makes it hard for antibiotics to get in and work to destroy the microbes.

Antibiotic resistance makes infectious diseases harder to treat and can turn common infections into life-threatening scourges. Many antibiotic resistant infections are picked up in hospitals, and the World Health Organization has consistently listed antibiotic resistance as a global health threat over the past few years because it has the potential to upend health care systems.

How the protein patchwork of the outer membrane might affect the strength of a bacteria’s protective covering or how it could help combat antibiotic resistance is not yet known. But with advanced microscopy techniques, scientists can shine a light on a previously unseen realm.

We May Know What the Next Nintendo Switch 2 Pokemon Game Will Be Called

A massive leak reveals potential details about the 10th generation of Pokemon games coming to the Nintendo Switch 2, including big changes.

A new Pokemon game, Pokemon Legends: Z-A, will be released for the Nintendo Switch and Switch 2 on Thursday, but a recent leak might have revealed info about what’s coming next from the creators of the franchise. The names of the next games headed to the Switch 2, as well as some of the big changes to the Pokemon formula, may have been part of the leak. 

The leak showed up on X Monday from the account Centro Leaks, as first spotted by Insider Gaming. Data about the upcoming games reportedly stems from a hack of the servers of the franchise developer Game Freak that happened in August 2024, referred to online as the Teraleak, that included the source code for the upcoming Pokemon Legenda: Z-A

Among the information shared by the account was the possible name for what would be the 10th generation of Pokemon games that would come to the Switch 2 next year: Pokemon Wind and Pokemon Wave. 

The Pokemon Company didn’t immediately respond to a request for confirmation about this leak. 

According to the leak, Pokemon Wind/Wave is inspired by the Southeast Asia region and will feature a jungle-themed environment. It could also feature a new mechanic referred to as a Seed Pokemon, which is reportedly a special Pokemon that is heavily involved in the story and must be raised by the player. As it evolves, it will have a unique look that is procedurally generated, and once it’s fully evolved, it will allow the player to gain access to an island where they can find the main legendary Pokemon of the game. 

The main theme of Pokemon Wind/Wave is the concept of infinity, according to the leak. This would match with the reported focus of procedurally generated content, not only with the special Seed Pokemon, but also with the islands of the game being procedurally generated, so each game is unique and could continue to grow with no end. 

Also included in the leak were other details, including Pokemon on the overworld being interactable, weather affecting gameplay in some way, 18 new challenges for players instead of traditional gyms, and a few screenshots of the game in development that are still available to see at the PokeLeaks subreddit. There was also info that the 11th-generation Pokemon game could be released in 2030. 

It is unlikely that Nintendo, The Pokemon Company or Game Freak will confirm the details of the leak. Expect to see the official announcement early next year, with the fall being the most likely release window for Pokemon Wind/Wave.
