UI study shows neighborhood conditions affect mortality, health outcomes

Does  where you live affect your health? Research has shown that neighborhoods with high socioeconomic deprivation also have higher mortality rates. But, those studies were a snapshot in time and did not consider how changes in socioeconomic deprivation—either positive or negative—corresponded to changes in health. Most research also didn’t track subjects over […]

‘Mini-placentas’ could provide a model for early pregnancy

Researchers say that new ‘mini-placentas’ – a cellular model of the early stages of the placenta – could provide a window into early pregnancy and help transform our understanding of reproductive disorders. Details of this new research were published in the journal Nature. Many pregnancies fail because the embryo does […]

Biologists discover an unusual hallmark of aging in neurons

As we age, neurons in our brains can become damaged by free radicals. MIT biologists have now discovered that this type of damage, known as oxidative stress, produces an unusual pileup of short snippets of RNA in some neurons. This RNA buildup, which the researchers believe may be a marker […]

Anti-Malaria Drugs Have Shown Promise in Treating Cancer, and Now Researchers Know Why

Anti-malaria drugs known as chloroquines have been repurposed to treat cancer for decades, but until now no one knew exactly what the chloroquines were targeting when they attack a tumor. Now, researchers from the Abramson Cancer Center of the University of Pennsylvania say they have identified that target – an enzyme called […]

A Lung Cancer Diagnosis and Treatment Revolution

Over the past 30 years, interventional cardiology has transformed heart care — replacing many interventions that used to require open-heart surgery with less invasive procedures. Today, that same revolution has arrived for pulmonary medicine with interventional pulmonology, or IP. The subspecialty offers a variety of minimally invasive procedures to diagnose […]

Surprising discovery about neurons, our irreplaceable nerve cells

Meticulous new research from the University of Virginia School of Medicine has changed a well-accepted scientific belief about neurons, the vital nerve cells that allow us to experience the world and record those experiences as memories in our brains. UVA’s new discovery reveals that these unique cells recycle and dispose […]

Cancer Researchers ID ‘Achilles Heel’ of Drug-Resistant Tumors

UC San Francisco scientists have figured out why some lung cancers become drug-resistant after initially responding to targeted therapies. In the process, they devised a new two-pronged approach that yields an effective treatment for these cancers in the laboratory and holds tremendous promise for the future of precision medicine, they […]

Discovery opens new opportunities to slow or reverse MS

Nerve cells stripped of their insulation can no longer carry vital information, leading to the numbness, weakness and vision problems often associated with multiple sclerosis. A new study shows an overlooked source may be able to replace that lost insulation and provide a new way to treat diseases like MS. […]

New biomedical gel could ease pain in cervical cancer treatment

A unique partnership between a Virginia Tech scientist and a University of Virginia oncologist could result in a solution to reduce discomfort during cancer treatment for women. Tim Long, a professor of chemistry with the Virginia Tech College of Science, and Tim Showalter, a radiation oncologist at UVA’s Cancer Center, are testing […]

Keeping aging brains healthy: lessons from genes

Do any genes protect against Alzheimer’s disease? And do any predispose a person to its ravages? The answer is yes to both, according to work led by U of M researcher Lisa James. Along with colleagues at the U of M and the Minneapolis VA Health Care System, James is […]

Study in mice suggests drug to turn fat ‘brown’ could help fight obesity

Our bodies contain two types of fat: white fat and brown fat. While white fat stores calories, brown fat burns energy and could help us lose weight. Now, scientists at the University of Cambridge have found a way of making the white fat ‘browner’ and increasing the efficiency of brown […]

AI system may accelerate search for cancer discoveries

Searching through the mountains of published cancer research could be made easier for scientists, thanks to a new AI system. The system, called LION LBD and developed by computer scientists and cancer researchers at the University of Cambridge, has been designed to assist scientists in the search for cancer-related discoveries. It is […]

Citrate-based biomaterial fuels bone healing with less rejection

A material based on a natural product of bones and citrus fruit, called citrate, provides the extra energy that stem cells need to form new bone tissue, according to a team of Penn State bioengineers. Their new understanding of the mechanism that allows citrate to aid in bone regeneration will […]

Brain Responses to Language in Toddlers with Autism Linked to Altered Gene Expression

An international team of scientists, led by researchers at the University of Cyprus and University of California San Diego School of Medicine, have identified a previously unknown, large-scale association between molecular gene expression activity in blood leukocyte cells and altered neural responses to speech in toddlers with autism as measured […]

Cells beneath the skin explain differences in healing

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 […]

Early gut bacteria shape intestinal ecosystem

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 […]

Researchers stop ‘sneaky’ cancer cells in their tracks

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 […]

Fish genes hold key to repairing damaged hearts

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 […]

Cutting the legs off cancer

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 […]

Modeling the most common form of vision loss in older adults

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 […]

Researchers discover a new gear in life's clock: Vitamin D

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 […]
