Dementia Spreads via Connected Brain Networks

In a new study, UC San Francisco scientists used maps of brain connections to predict how brain atrophy would spread in individual patients with frontotemporal dementia (FTD), adding to growing evidence that the loss of brain cells associated with dementia spreads via the synaptic connections between established brain networks. The […]

Research on cell division provides new clues to how a common cancer treatment works

When chemotherapy was first invented, its premise seemed relatively simple: to curb the growth of tumors by stopping their cells from proliferating. Today, many of these drugs are known to act through different mechanisms and have turned out to be useful only in certain tumor types and patients. Consider the […]

Scientists have first 3D view of life's processes in liquid

A new liquid-cell technology allows scientists to see living biological materials and systems in three dimensions under an electron microscope, according to researchers at Penn State, Virginia Tech and Protochips Inc. “With this technology that we developed in collaboration with Protochips, scientists could analyze host-pathogen interactions, see a virus being […]

New method visualizes groups of neurons as they compute

Using a fluorescent probe that lights up when brain cells are electrically active, MIT and Boston University researchers have shown that they can image the activity of many neurons at once, in the brains of mice. This technique, which can be performed using a simple light microscope, could allow neuroscientists […]

Researcher develops nanosystem that promotes regeneration after root canals

A novel nanosystem developed by Anil Kishen, a professor in the University of Toronto’s Faculty of Dentistry, shows promising results in promoting healing and regeneration by host tissues following root canals. Kishen’s research was published recently in the medical journal Nanomedicine: Nanotechology, Biology and Medicine. The current treatment for root canals focuses on […]

For Low-Risk Thyroid Cancer Patients, Less May be More for Post-surgery Surveillance

Not all patients feel the same way about medical treatment. Some are “minimizers,” preferring to see a doctor as little as possible and to give health issues a chance to resolve on their own. Others are “maximizers” who want to treat a disease to the fullest extent possible, even if […]

Mounting Brain Organoid Research Reignites Ethical Debate

As research involving the transplantation of human “mini-brains”—known as brain organoids—into animals to study disease continues to expand, so do the ethical debates around the practice. One concern is the possibility, however minute, that the grafted organoids may one day induce a level of consciousness in host animals, as models […]

Student’s curiosity about his family’s cancer history fuels award-winning research project

Connor Harris, a science-minded teenager from Hudson, Ohio, wants to know why African-Americans die from colorectal cancer at a higher rate than other racial groups. His curiosity, fueled by his own family history of cancer, led to a 2018 summer internship program at Case Comprehensive Cancer Center (CCCC) to engage […]

Cancer Patients Want to Pull Back the Curtain on Pathology

Some of the most important players on a cancer patient’s health care team are people they typically never meet or interact with — the pathologists who evaluate their tissue samples to determine the type and stage of disease they have. And as interest in patient-pathologist consulting programs has gained momentum […]

With NIH support, FSU sleep detective taking closer look at human clock genes

The phrase “like clockwork” suggests that clocks never go haywire. But they do. So do the internal clocks that are supposed to keep ticking to the beat of Earth’s 24-hour circadian rhythms. When our own rhythms are disrupted, one result is often a sleep disorder — which, over time, can […]

Metastatic Breast Cancer: What You Should Know

After hearing a diagnosis of metastatic breast cancer, a rush of questions emerges. But often, it’s not until long after leaving the doctor’s office. Metastatic means the cancer has spread beyond the breast and immediate lymph nodes to other organs or tissues in the body, most often the bones, brain, lungs […]

Fresh insights could lead to new treatments for liver disease

The fight against liver disease could be helped by the discovery of cells that cause liver scarring. Scientists have identified new sub-types of cells that, when they interact, accelerate the scarring process in diseased livers. Experts hope that by understanding more how these cells behave, new treatments can be developed […]

No need to cut down red and processed meat, says study

Most people can continue to eat red and processed meat as they do now. A major study led by researchers at McMaster and Dalhousie universities has found cutting back has little impact on health. A panel of international scientists systematically reviewed the evidence and have recommended that most adults should […]

International study finds similar results from total or partial hip replacement

To do a total or partial hip replacement for older adults who have a hip fracture has been the question. Now a large clinical study of almost 1,500 patients in 10 countries world-wide has found those who had a total hip arthroplasty have modestly better function after two years, but […]

UVA Identifies surprising contributor to multiple sclerosis

Cells that scientists have largely ignored when studying multiple sclerosis are actually key contributors to MS development, new research from the University of Virginia School of Medicine shows. The discovery suggests new avenues for devising treatments and is a vital step toward finding a cure. Understanding Multiple Sclerosis Scientists had assumed […]

Novel nanogels hold promise for improved drug delivery to cancer patients

NSF-funded researchers at The University of Texas at Austin have developed new guidelines for fabricating nanoscale gel materials, or nanogels, that can deliver therapeutic remedies to treat cancer in a precise manner. In addition to enabling the delivery of drugs to tumors, the nanogels can target malignant cells and degrade into nontoxic […]

Study: To fight effects of sleep deprivation, reach for healthy snacks

Nutrition scientist  Maryam Hamidi, PhD, conducted research recently which required her to repeatedly stay awake from 8 a.m. until 5 a.m. the next day. As part of the study, she also needed to keep supplies of both healthy and unhealthy snacks stacked in her office. Then, somewhere along the line, […]

Yale researchers develop way to help brain organoids thrive

Brain organoids created from human embryonic stem cells offer scientists a powerful way to study the developing brain in three dimensions. However, organoids need nutrients and oxygen carried in blood to thrive, just as a developing fetal brain does. Now Yale researchers have developed a method to induce growth of […]

Immune Cell Identity Crisis: What Makes a Liver Macrophage a Liver Macrophage?

Every tissue in the human body has an immune cell in it called a macrophage. Macrophages play important roles in the immune system’s initial response to bacteria, viruses and wounds. But beyond that, each tissue macrophage also has specialized functions, tuned to the needs of that particular tissue. For example, […]
