The bacteria that call your gut home can have a tremendous impact on your overall health, but exactly how the bugs do so is a web that’s still being untangled. To investigate, researchers at Harvard Medical School have deleted a single gene from one gut bacteria species and found that it alters the metabolism of the host, reducing their weight gain.
Cerebral small vessel disease (SVD) is one of the most commonly associated causes of age-related dementia and stroke. New research, led by the University of Edinburgh, may have finally uncovered the mechanism by which SVD causes brain cell damage, as well as a potential treatment to prevent the damage, and possibly even reverse it.
Cancer is one of humanity’s biggest killers, but scientists are coming up with some creative ways to fight back. Researchers at the University at Buffalo have developed new kinds of nanoparticles that can infiltrate, heat up and kill cancer cells more effectively and efficiently than similar methods.
Strong and light, spider silk is one of the most impressive materials in the natural world. Both the real thing and synthetic versions have been used to improve everything from clothing to car seats, cooling electronics to preserving produce, making sweet music or helping people hear it, and even patching up severed nerves. Now, scientists in Germany and Switzerland have found a new use for spider silk – wrapping up cancer drugs to protect them until they can reach their tumorous targets.
Antibiotics are effective at killing bacteria (for now, at least), but they aren’t very picky, indiscriminately wiping out both good and bad bacteria. This can upset the fragile balance of your microbiome, which is increasingly being linked to general health and wellbeing. Now, researchers at Penn State have developed a new approach to make a drug that can single out a specific, opportunistic bacteria known as C. difficile.
Futuristic ‘smart’ tissues could grow into any organ and automatically connect to the bodies of transplant patients, study reveals
Scientists have created synthetic tissues that can rebuild themselves into any part of the body, a new study reveals.
The researchers developed a new compound that mimics DNA’s instructions for cells to turn into various tissues.
Using this method, the University of California, San Francisco team could effectively automate these cells to take on various structures and colors, a process akin to what happens in the early stages of natural embryonic development.
Glioblastoma is one of the most deadly forms of cancer. Affecting the brain, those unlucky enough to receive a diagnosis don’t have many treatment options – and usually a median life expectancy of just over a year. Now, researchers at MIT have developed nanoparticles that could provide hope, crossing the blood-brain barrier and delivering two types of drugs to fight tumors.
At the cellular level, aging and cancer are two sides of the same coin. The mechanism that limits a cell’s lifespan can be slowed down, but that can turn them cancerous, as they divide unchecked.
