Air pollution affects brain development – but when does the damage start?

The emergency rooms in Barcelona were collapsing under the pressure. Hundreds of patients were arriving in desperate need as they struggled to breathe, while intensive care units struggled to cope with the sudden influx of respiratory problems. Epidemiologists scrambled to trace the source of the outbreak. This epidemic in the […]

Fruit flies help shed light on tumor formation, migration and growth

What can the common fruit fly teach us about cancer? “Over the last few decades, the fruit fly – Drosophila melanogaster – has become a successful model for studying human cancers,” said Wu-Min Deng, Ph.D., professor of biochemistry and molecular biology and the Gerald and Flora Jo Mansfield Piltz Professor of […]

Flatworms muscle new eyes' wiring into their brains

Peter Reddien's lab at the Whitehead Institute takes a step forward in understanding how neural circuits could be regenerated in adults. If anything happens to the eyes of the tiny, freshwater-dwelling planarian Schmidtea mediterranea, they can grow them back within just a few days. How they do this is a scientific conundrum […]

Stem Cell Exhaustion in the Aging Lung

Stem cell activity declines with age throughout the body. In some cases this is because stem cells become less active in response to changes in the signaling environment. In other cases, the cells are damaged or the populations greatly reduced. The consequence of this decline is that fewer daughter somatic […]

Scientists discover way to stop spread of devastating childhood cancer

Researchers at the University of East Anglia and the University of Manchester have made an important breakthrough that could lead to ‘kinder’ treatments for children with bone cancer, and save lives. Current treatment is grueling, with outdated chemotherapy cocktails and limb amputation. But despite all of this, the five-year survival […]

Multiple Purkinje cell types: A new logic of cerebellar organization in zebrafish

In a study published in PNAS, researchers from Karolinska Institutet, the Royal Institute of Technology (KTH), Nagoya University and Technische Universität Braunschweig show an undiscovered heterogeneity of adult zebrafish Purkinje cells, revealing the existence of anatomically and functionally distinct cell types. The cerebellum, sometimes referred to as the “tree of […]

New Drug Combo Shows Promise in Fight Against High Cholesterol

If you’ve ever been diagnosed with high cholesterol, also known as hyperlipidemia, your doctor has probably prescribed a statin. And while statins have been the go-to drug for managing cholesterol for nearly 25 years, there’s a new weapon in the fight. Recent studies suggest that adding a new class of medications — either […]

Swap Meet

Researchers at Harvard Medical School, the Broad Institute of MIT and Harvard and Brigham and Women’s Hospital have uncovered a genetic mechanism that helps drive clonal hematopoiesis, a common age-related condition known to increase the risk of blood cancer and cardiovascular disease. In clonal hematopoiesis or CH, some blood stem […]

NFL outperforms other blood tests to predict and diagnose traumatic brain injury

A study from the National Institutes of Health showed that neurofilament light chain (NfL) delivered a superior diagnostic and prognostic performance as a blood biomarker for mild, moderate, and severe traumatic brain injury (TBI) when compared to blood proteins glial fibrillary acidic protein, tau, and ubiquitin c-terminal hydrolase-L1. The research […]

It is Challenging to Find Support for Evolutionary Trade-offs Between Reproduction and Aging in Human Data

The disposibility theory of aging is one of numerous evolutionary theories of aging that seek to explain why aging exists and is near universal across species. In this case, aging is viewed as the inevitable result of trade-offs between resources allocated to reproduction versus resources allocated to tissue maintenance. Like […]

NIH researchers reframe dog-to-human aging comparisons

One of the most common misconceptions is that one human year equals seven dog years in terms of aging. However, this equivalency is misleading and has been consistently dismissed by veterinarians. A recent study, published in the journal Cell Systems(link is external), lays out a new framework for comparing dog-to-human aging. In […]

Fertility decline in ageing fruit flies is about ‘more than just sperm’

Research by the universities of Liverpool and Oxford reveals new insight into age-related fertility decline in male fruit flies. Infertility is one of the most striking effects of ageing. The impact of ageing on females’ fertility is more severe and much better understood, but it also affects males. Male reproductive […]

Living close to natural green space benefits gut bacteria of urban, formula-fed infants

First study of its kind shows formula-fed babies’ gut microbiomes more like those of breastfed babies when they live near natural environments. Living close to natural green space can mitigate some of the changes in infant gut bacteria associated with formula feeding, according to new research published in the journal Environment International. “Not […]

New database aims to make Alzheimer's diagnosis easier and earlier

Volunteers can add data with a five-minute online session. Do you get nervous when you can’t think of a word? Chances are it’s a momentary lapse, but problems with language are one of the symptoms that can indicate a neurodegenerative disorder like Alzheimer’s disease. Unfortunately, diagnosing these conditions requires scoring […]

Sensory Neurons Outside the Brain Drive Autistic Social Behaviors, Penn Study Suggests

A new study from Penn Medicine lends further evidence that the social behaviors tied to autism spectrum disorders (ASD) emerge from the abnormal function of sensory neurons outside the brain. It’s an important finding, published in the journal Cell Reports because peripheral sensory systems—which determine how we perceive the environment around us […]

To Let Neurons Talk, Immune Cells Clear Paths Through Brain’s ‘Scaffolding’

To make new memories, our brain cells first must find one another. Small protrusions that bud out from the ends of neurons’ long, branching tentacles dock neurons together so they can talk. These ports of cellular chatter – called synapses, and found in the trillions throughout the brain – allow […]

Dissecting fruit flies’ response to life-extension diet

Changes in a few small molecules involved in a cell’s metabolism seem to indicate whether a restricted “life extension” diet will actually extend, shorten, or have no effect on lifespan, a study of fruit flies has found. The findings suggest that analyzing the level of small molecules in cells, an […]

Yale, Baylor create detailed atlas of cellular change in lungs with fibrosis

A research team from Yale and Baylor College of Medicine has completed the largest single-cell analysis to date of lungs affected by Idiopathic Pulmonary Fibrosis (IPF), revealing how cells change in response to the disease and identifying previously unknown cell types. The findings, published in the issue of Science Advances, deepen […]

Brd2 Inhibition as an Approach to Slow Aging

There are innumerable studies showing small gains in mouse life span. Most cannot be reproduced, particularly the older ones, those that took place before it was common knowledge in the research community that one has to very aggressively control for accidental calorie restriction. If an intervention makes mice eat less, […]

The Aging Gut Microbiome Produces More Trimethylamine, Harming Arterial Function

In recent years academic interest has grown in the study of the gut microbiome. Researchers are making inroads into understanding the considerable influence of these microbial populations over the progression of health and aging. The gut microbiome may be as influential as physical activity in these matters. The balance of […]
