Researchers at MIT are using AI systems to design new molecules for potential antibiotics, research that is “aimed at the growing challenge of antibiotic-resistant infections,” reports Adele Peters for Fast Company. “The number of resistant bacterial pathogens has been growing, decade upon decade,” says Prof. James Collins. “And the number of new antibiotics being developed has been dropping, decade upon decade.”
Prof. Bryan Bryson speaks with Chris Smith on The Naked Scientists podcast about his efforts to find targets for a new tuberculosis vaccine, as the current version, which is very effective in children, does not sufficiently protect adolescents and adults. “Right now, we only have one TB vaccine that's over 100 years old,” said Bryson. “And for me as an engineer, if somebody tells you there's a 100 year old technology that doesn't work the way that you want it to, you want to say, let's build a better one.”
Prof. Bryan Bryson and his colleagues have identified a series of targets for a new tuberculosis vaccine. The “researchers identified proteins expressed on the surface of cells infected with TB and used mRNA to coax uninfected human cells to produce the bacterial compounds, a key first step toward new vaccines,” writes Darren Incorvaia for Fierce Biotech.
Prof. Linda Griffith and her colleagues have “developed a model of the human gut to study how the organ’s microbes interact with immune cells and regulate inflammation,” reports Gemma Conroy for Nature. Griffith and her team “have also created models for endometriosis and pancreatic cancer,” writes Conroy.
Using AI, researchers at MIT have developed new antibiotics for gonorrhoea and MRSA, two infections that are typically hard to treat. The team “trained the AI to help it learn how bacteria was affected by different molecular structures built of atoms in order to design new antibiotics,” writes Ruth Stainer for the Daily Mail. “[A]nything too similar to the current antibiotics available, or with the potential to be toxic to human beings, was eradicated.”
Researchers at MIT used AI to “design antibiotics that can tackle hard-to-treat infections gonorrhoea and MRSA,” reports ITV News. "Our work shows the power of AI from a drug design standpoint, and enables us to exploit much larger chemical spaces that were previously inaccessible,” says Prof. James Collins.
Using generative AI, researchers at MT have designed new antibiotics to combat MRSA and gonorrhea, reports James Gallagher for the BBC. "We're excited because we show that generative AI can be used to design completely new antibiotics," says Prof. James Collins. "AI can enable us to come up with molecules, cheaply and quickly and in this way, expand our arsenal, and really give us a leg up in the battle of our wits against the genes of superbugs."
Prof. Katharina Ribbeck speaks with New York Times reporter Nina Agrawal about her research studying the health and medical benefits of mucus. “Ribbeck’s research has shown that the sugars on mucins can effectively switch off mechanisms that the bacteria involved in strep throat or cholera, for example, or fungus in a yeast infection, use to go from innocuous to harmful,” explains Agrawal.
New York Times reporter Eric Lipton spotlights Prof. Christopher Voigt and his team’s “radical effort to engineer nature to fight climate change” by creating genetically modified bacteria to help reduce the use of chemical fertilizers. Lipton notes that Voigt is “a rock star of sorts in the fast-growing field of biological engineering.”
MIT researchers have discovered a protein found in human sweat that holds antimicrobial properties and can “inhibit the growth of the bacteria that causes Lyme disease,” reports Matt Fortin for NENC. The team believes this “type of protein could be put into a topical cream to make something called ‘Lyme Block’ – like sunblock, but for preventing Lyme.” "Ideally what we would love to do is give people more control over their own risk," says Principal Research Scientist Michal Tal. "And really try to develop this into a possible preventative that you could put on repellant or sunblock to protect against other elements of the outdoors that you could also protect yourself against Lyme."
Prof. Katharina Ribbeck speaks with Christopher Intagliata of Scientific American’s “Science Quickly” podcast about her research exploring how mucus can treat and prevent disease. “The basic building blocks of mucus that give mucus its gooey nature are these threadlike molecules—they look like tiny bottlebrushes—that display lots and lots of sugar molecules on their backbone,” explains Ribbeck. “And these sugar molecules—we call them glycans—interact with molecules from the immune system and microbes directly. And the exact configuration and density of these sugar molecules is really important for health.”
Researchers from MIT and elsewhere have isolated a “protein in human sweat that protects against Lyme disease,” reports Matthew Rozsa for Salon. The researchers believe that if “properly harnessed the protein could form the basis of skin creams that either prevent the disease or treat especially persistent infections,” writes Rosza.
Graduate student Lauren “Ren” Ramlan programmed Doom, an iD software video game, to run on a display made from E.coli cells, reports Andrew Paul for Popular Science. For the project to work, “Ramlan first grew cells within a 32×48 1-bit well plate, then connected the makeshift screen to a controller capable of processing and translating binary code into the ‘addition or omission of a repressor controlling the fluorescence of the cells,’” writes Paul. “Basically, Ramlan swapped a traditional screen’s tiny light diodes for glowing bacterial cells."
MIT researchers have “used an algorithm to sort through millions of genomes to find new, rare types of CRISPR systems that could eventually be adapted into genome-editing tools,” writes Sara Reardon for Nature. “We are just amazed at the diversity of CRISPR systems,” says Prof. Feng Zhang. “Doing this analysis kind of allows us to kill two birds with one stone: both study biology and also potentially find useful things.”
Researchers from MIT and elsewhere have “genetically engineered bacteria to efficiently turn plastic waste into useful chemicals,” reports Aristos Georgiou for Newsweek. MIT Prof. James Collins and University of Illinois Urbana-Champaign Prof. Ting Lu explain that they see two potential applications for their work. "In the former case, plastic waste collected from oceans and landfills would be transported to a facility where it would be bioprocessed with engineered microbes,” they note. “In our latter scenario, these microbes could be deployed directly in lands or oceans to bio-transform plastic debris in situ.”
