USA Today reporter Sean Rossman writes about how MIT researchers have created an ingestible sensor that can monitor the digestive tract and send information to a smartphone or tablet about a person’s health. Rossman explains that the device, “can detect blood in the stomach, something that would otherwise require an endoscopy and sedation.”
MIT researchers have developed an ingestible capsule that uses genetically engineered bacteria to detect potential health problems, reports Carla Johnson for the Associated Press. The researchers hope the capsule could eventually be used to, “find signs of ulcers, inflammatory bowel disease or even colon cancer.”
Wired reporter Megan Molteni writes that a team of MIT researchers has developed an ingestible sensor that could spot gastrointestinal issues. The sensor contains, “millions of genetically engineered glowing bacteria inside a AAA-battery-sized capsule,” Molteni explains.
Writing for the Boston Herald, Lindsay Kalter reports that MIT scientists have built an ingestible capsule that could allow doctors to diagnose gastrointestinal diseases without invasive procedures. Graduate student Mark Mimee explains that the device, “sets the stage for having a pill that can give you a big biochemical profile of the gut related to various diseases.”
Popular Mechanics reporter David Grossman writes that a new ingestible medical device developed by MIT researchers could monitor the health of the human gut. Calling the project “a true team effort,” Grossman explains that it required expertise in biological engineering techniques, electronic circuit design, materials, and gastroenterology.
Elise Takahama writes for The Boston Globe that MIT researchers have developed a new technique to create “xenoproteins,” manmade proteins that could be used to battle infectious diseases like Ebola. Unlike drugs developed with natural proteins, the xenoproteins, “are more stable, easier to administer, and manufactured more quickly,” Takahama explains.
Assistant Prof. Lydia Bourouiba is highlighted in a documentary series that aims to inspire future generations of women in STEM. Producer Emily Driscoll writes in Scientific American that Bourouiba’s work studying droplets from sneezes and toilet flushes “could mean new designs for hospitals and our understanding of disease transmission.”
60 Minutes correspondent Bill Whitaker sits down with Prof. Feng Zhang, “a scientist at the center of the CRISPR craze,” to help explain how the gene-editing tool works and its potential. “There are about 6,000 or more diseases that are caused by faulty genes,” says Zhang. “The hope is that we will be able to address most if not all of them.”
Research published in Science Translational Medicine suggests that inflammation caused by tumor removal surgery may actually encourage the emergence of new tumors. Daniel Uria for UPI reports that the study, led by Prof. Robert Weinberg, identified “perioperative anti-inflammatory treatment” as a way to substantially reduce the likelihood of “early metastatic recurrence in breast cancer patients.”
New research from MIT and the Whitehead Institute suggests that “the body’s own mechanism for healing” may cause cancerous cells to spread after breast cancer-related surgeries, reports Karen Weintraub for WBUR CommonHealth. “The post-surgical wound-healing response somehow releases…cells that have already spread to distant sites in the body,” explains Prof. Robert Weinberg, “releasing them from the constraints that have previously prevented them from growing actively.”
Synlogic, founded by Prof. Jim Collins and Associate Prof. Tim Lu, is programming probiotic bacteria to treat certain genetic or acquired metabolic disease, reports Robin Seaton Jefferson for Forbes. One product is used for people whose bodies can’t maintain a healthy level of ammonia and “has been specifically engineered to convert the excess ammonia to a harmless metabolite,” explains Seaton Jefferson.
Research published in Neuron may allow for the development of new treatments for disorders associated with memory loss. “It’s possible that further research on the dentate gyrus-CA3 pathway could lead to ways to restore the synapses to allow memory formation again,” Prof. Yingzi Lin told Elise Takahama for the Boston Globe.
Researchers have found a way to reactivate the gene that causes fragile X syndrome, the most common inherited form of intellectual impairment. “The team used an emerging technique called “epigene-editing”,” writes Alice Klein for New Scientist, which is reversible. “That means any off-target effects could be fixed and wouldn’t be passed to future generations.”
Originally created by the Zhang Lab in 2017, CRISPR tool SHERLOCK has been improved upon to be three times more sensitive for detecting viruses and infections using an inexpensive test strip. Sharon Begley writes for STAT News, “A paper strip, like in a pregnancy test, is dipped into a sample, and if a line appears, the target molecule was detected — no instruments required.”
A gene-editing tool called SHERLOCK, developed in Prof. Feng Zhang’s lab, allows for faster detection of infections and viruses, such as Zika and Dengue fever. “It does this by combining different types of CRISPR enzymes, which are unleashed together to target distinct bits of DNA and RNA, another of the major biological molecules found in all forms of life,” writes Alessandra Potenza for The Verge.
