Differences in the cells that give skin its resilience and strength during wound repair may explain why individuals heal differently, according to a new Yale study published in the journal Science. Fibroblasts, the cells that form the protein structure beneath the surface of the skin, were once thought to be […]

The study suggests that the order in which bacterial species stake out unclaimed territory in the gut can shape an intestinal ecosystem for a lifetime, potentially shifting the odds of certain health outcomes in the process. Though timing wasn’t everything, multiple experiments showed that species given early access to the […]

A new study by University of Minnesota biomedical engineers shows how they stopped cancer cells from moving and spreading, even when the cells changed their movements. The discovery could have a major impact on millions of people undergoing therapies to prevent the spread of cancer within the body. The research […]

In the first paper to emerge from a series of research projects aimed at understanding the health needs of older adults who identify as lesbian, gay, bisexual, transgender and queer (LGBTQ), Jason Flatt of the Institute for Health & Aging at the UC San Francisco School of Nursing found that nearly 25 percent of the LGBT adults aged […]

The Mexican tetra fish can repair its heart after damage — something researchers have been striving to achieve in humans for years. Now, new research funded by the British Heart Foundation (BHF) published in Cell Reports suggests that a gene called lrrc10 may hold the key to this fish’s remarkable ability. Around 1.5 million […]

Melanoma skin cancer tumors grow larger and are more likely to metastasize due to interactions between a pair of molecules, according to experiments in mice and human cells. The results may restore the potential for a type of cancer therapy previously abandoned in clinical trials. The results also implicate one […]

Age-related macular degeneration (AMD) affects roughly 200,000 individuals in the United States each year. In most, it comes on slowly, gradually blurring the central field of vision used for activities like reading and driving. While treatments exist to slow its progression, there is no cure. A team led by Kathleen Boesze-Battaglia of […]

To treat and prevent pregnancy-related disorders, researchers must understand not only what can go wrong, but when. Complications, such as preeclampsia and pre-term birth, often occur in the second or third trimester, and most research to date has focused on those later stages of pregnancy. But the biological events that […]

It takes a lot of cells to make a human brain. The organ houses not only an enormous quantity of neurons (tens of billions), but also an impressive diversity of neuron types. In recent years, scientists have been developing inventories of these cell classes—information that will be essential for understanding […]

New research from Portland State University finds vitamin D, or a lack thereof can trigger or suspend embryonic development in a species of fish. The study also provides evidence suggesting the vitamin is critical to the early development of vertebrates generally. The annual killifish Austrofundulus limnaeus lives its entire life in seasonal ponds […]

Research on a bacterial toxin first discovered in Adelaide has led to the development a new blood test for the early diagnosis of ovarian cancer – a disease which kills over 1000 Australian women and 150,000 globally each year. The new blood test has the potential to dramatically improve early […]

In two recently published papers, a scientific team at Case Western Reserve University School of Medicine reports on the discovery and implementation of a new, more efficient method for generating an important brain stem cell in the laboratory. The findings pave the way for greater understanding of the underlying mechanisms […]

A new study by researchers at Karolinska Institutet supports the theory that replacement of dysfunctional immune cells in the brain has therapeutic potential for neurodegenerative diseases like ALS and Alzheimer’s disease. The study, which involved repopulating the brain with new immune cells in an experimental disease model, is published in Nature […]

In the first large-scale analysis of cardiovascular complications linked to immune checkpoint inhibitors, Vanderbilt researchers have shown that heart and vessel complications include myocarditis, pericarditis, vasculitis and arrhythmias, and that they occur early in the course of treatment. The study, published online in The Lancet Oncology, augments previous work by Vanderbilt […]

A team of scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University have identified three genes responsible for recurrent molar pregnancies, a rare complication that occurs when a non-viable pregnancy with no embryo implants in the uterus. The results of this study could have […]

The Department of Microbiology and Immunobiology at Harvard Medical School will form two independent preclinical departments—Microbiology and Immunology. The creation of two stand-alone academic units is the natural result of the rapidly evolving understanding of the complexity and importance of each of these fields and their numerous intersections with many […]

Epigenetic therapies, which target enzymes that alter the genes that are turned on or off in a cell, are of growing interest in oncology as a way to make cancers less aggressive or less malignant. But now, at least one epigenetic therapy that had looked promising for lung cancer appears […]

Cancer involves unchecked cell growth. A biological pathway known as Hippo, which regulates organ size, is also involved in cancer, and a major player in this pathway, YAP, drives many types of tumors. Now, researchers at Harvard Medical School and Boston Children’s Hospital have solved an ongoing problem: how to […]

One day, MRI brain scans may help predict whether older people will develop dementia, new research suggests. In a small study, MRI brain scans predicted with 89 percent accuracy who would go on to develop dementia within three years, according to research at Washington University School of Medicine in St. […]

Researchers from the University of Minnesota, the Howard Hughes Medical Institute, and the University of Toronto have discovered a possible path forward in preventing the development of cancers tied to two viruses, including the virus that causes infectious mononucleosis—more commonly known as mono or the “kissing disease”—that infects millions of people around the […]

Researchers at the University of New Hampshire have created an easy-to-make, low-cost injectable hydrogel that could help wounds heal faster, especially for patients with compromised health issues. Wound healing can be complex and challenging, especially when a patient has other health obstacles that seriously impede the process. Often injectable hydrogels […]

Scientist have cast new light on the behaviour of tiny hair-like structures called cilia found on almost every cell in the body. Cilia play important roles in human development and disease. Akin to tiny antennae, they act as cell timers keeping the brakes on cell division until the right growth […]

Scientists have developed a potential new therapeutic approach for synovial sarcoma, one of the most common soft-tissue cancers in teenagers and young adults. At present the long-term survival rates for synovial sarcoma patients is well below 50%; a fact that underlines just how important new discoveries are if we are […]

Scientists have equipped a virus that kills carcinoma cells with a protein so it can also target and kill adjacent cells that are tricked into shielding the cancer from the immune system. It is the first time that cancer-associated fibroblasts within solid tumours – healthy cells that are tricked into […]

Mapping of a certain group of cells, known as oligodendrocytes, in the central nervous system of a mouse model of multiple sclerosis (MS), shows that they might have a significant role in the development of the disease. The discovery can lead to new therapies targeted at other areas than just […]

Pushing the limits of cryo-electron microscopy, University of California, Berkeley, scientists have captured freeze-frames of the changing shape of a huge molecule, one of the body’s key molecular machines, as it locks onto DNA and loads the machinery for reading the genetic code. The molecule, called transcription factor IID, is […]

A single season of high school football may be enough to cause microscopic changes in the structure of the brain, according to a new study by researchers at UC Berkeley, Duke University and the University of North Carolina at Chapel Hill. The researchers used a new type of magnetic resonance […]

New parents often expect their baby to start sleeping through the night by around six months of age. Indeed, they often receive messages from paediatricians and others about the importance of early sleep consolidation. But authors of a study in the issue of Pediatrics found that a large percentage of healthy babies […]

Certain genes that code for proteins have long been known to contribute to cancer progression. But in a frame shift, researchers from Case Western Reserve University School of Medicine recently found that non-coding genes also contribute to the development and spreading of the disease, one of the first known examples […]
