Exploring the cellular neighborhood

Cells rely on complex molecular machines composed of protein assemblies to perform essential functions such as energy production, gene expression, and protein synthesis. To better understand how these machines work, scientists capture snapshots of them by isolating proteins from cells and using various methods to determine their structures. However, isolating proteins from cells also removes […]

How sensory gamma rhythm stimulation clears amyloid in Alzheimer’s mice

Studies at MIT and elsewhere are producing mounting evidence that light flickering and sound clicking at the gamma brain rhythm frequency of 40 hertz (Hz) can reduce Alzheimer’s disease (AD) progression and treat symptoms in human volunteers as well as lab mice. In a new open-access study in Nature using a mouse model of the […]

Cultivated Meat’s Empty Promise of Revolution

It is a gleaming vision of a world just beyond the present: a world in which meat is abundant and affordable with almost no cost to the environment. Animal slaughter is forgotten. Global warming is restrained. At the heart of the vision is a high-tech factory housing steel tanks as tall as apartment buildings and […]

For Health, More Nuts, Beans and Whole Grains In Your Diet

The case has never been clearer: Eat less bacon and more beans. An analysis published Wednesday in the journal BMC Medicine, drawing on data from 37 studies, adds to the evidence that eating fewer animal-based foods — especially processed meats — and replacing them with whole grains, legumes and nuts is linked to a reduced […]

Many Younger Women Are Iron Deficient: Risks, Causes and Symptoms

Iron that isn’t used for hemoglobin or other functions is stored in the bone marrow and liver as a protein called ferritin. When the body’s iron stores dip, the remaining iron is redirected to the maintenance of red blood cells at the expense of heart, brain and muscular functions, Dr. Munro said. If the body […]

Scientists Use CRISPR to Make Chickens More Resistant to Bird Flu

Scientists have used the gene-editing technology known as CRISPR to create chickens that have some resistance to avian influenza, according to a new study that was published in the journal Nature Communications on Tuesday. The study suggests that genetic engineering could potentially be one tool for reducing the toll of bird flu, a group of […]

Future science at the molecular level

Innovating at the intersection of chemistry, biology, and engineering, Professor Brad Pentelute and the Pentelute Lab at MIT invent new chemistry, platforms, and techniques that might revolutionize therapeutics. Their formula in brief: nature-inspired research that begins at the molecular level, infused with state-of-the-art machine learning and automation, aimed at solving real-world problems. Take, for example, […]

Study explains how part of the nucleolus evolved

Inside all living cells, loosely formed assemblies known as biomolecular condensates perform many critical functions. However, it is not well understood how proteins and other biomolecules come together to form these assemblies within cells. MIT biologists have now discovered that a single scaffolding protein is responsible for the formation of one of these condensates, which […]
