In vivo drug discovery for β-cell proliferation in diabetes

In a study published in Nature Metabolism, researchers at the Department of Cell and Molecular Biology developed a novel technique to identify small molecules that can make insulin-producing β-cells divide. Olov Andersson and Jeremie Charbord explain: Diabetes is characterized by the progressive loss of functional β-cells. One possible approach to curing diabetes is […]

Electrical nerve stimulation research could pave the way to new treatments

A project to measure the effects of electrical stimulation of a major nerve that could hold the key to new treatments for a range of diseases from epilepsy to depression is underway at the University of Bath. Members of C3Bio, the University’s Centre for Biosensors, Bioelectronics and Biodevices, are working to […]

Microglia Become More Pro-Inflammatory in the Aging Brain

In this open access commentary, the authors discuss efforts to uncover the mechanisms by which microglia in the aging brain are primed to undertake inflammatory responses, more so than those in the young brain. This may be due in part towards increased numbers of senescent microglia, secreting pro-inflammatory signals. This […]

New findings to boost IVF success rates

In vitro fertilization fulfils the wishes of half a million parents each year, yet fertility treatment leaves plenty of room for improvement. A majority of potential embryos are ruled out for implantation, flagged by a genetic test designed to root out abnormalities early on.  This selection process limits the success […]

Flickering Lights and Sound Could Be New Weapon Against Alzheimer’s

For the past few years, Annabelle Singer and her collaborators have been using flickering lights and sound to treat mouse models of Alzheimer’s disease, and they’ve seen some dramatic results. Now they have resulted from the first human feasibility study of the flicker treatment, and they’re promising. “We looked at safety, tolerance, and adherence, […]

Nasal spray could be used to treat Parkinson's disease

Parkinson’s disease is an incurable neurodegenerative condition, affecting millions of people in the world. It is one of the leading causes of age-related dementia as well as a very common cause of disability or death. Now scientists at the University of York are pushing to make a nasal spray treatment […]

People with familial longevity show better cognitive aging

If you come from a family where people routinely live well into old age, you will likely have better cognitive function (the ability to clearly think, learn and remember) than peers from families where people die younger. Researchers affiliated with the Long Life Family Study (LLFS) recently broadened that finding […]

Imaging project finds the machinery behind brain cells

Ultrahigh-resolution, high-speed imaging of fruit fly brains has allowed University of Oregon scientists to capture mechanical motions that stem cells use to make neurons, the cells that make up the brain. The motions coordinate cell division during differentiation, when some newly born cells become neurons. Differentiation is essential for building […]

Researchers intend to discover microbiome’s role in personalized nutrition

Personalized nutrition has emerged in recent years as a key potential solution to a variety of diseases that originate in the gut, and Nebraska scientists are mining microbiome data to determine how individuals’ digestive systems might respond to different nutritional approaches. Ultimately, these findings could help scientists and doctors recommend […]

Brain’s memory center stays active during ‘infantile amnesia’

One trait shared by all humans is that they don’t remember specific life episodes that occurred before the age of 3 or 4.  Many scientists have attributed this so-called “infantile amnesia” to a lack of development in the hippocampus, an area of the brain located in the temporal lobe that is […]

Nerve signaling alerts the host to bacterial infection within hours

An exciting new way has been found in which the body senses a bacterial infection within 4 hours and uses nerve pathways to trigger an immune response in distant organs. The speed by which an infection can be identified, and how the defence mechanisms are triggered is critical to infection […]

Targeting Microglia in the Aging Brain

The progressive age-related dysfunction of microglia in the aging brain is implicated in the progression of neurodegenerative disease, as well as the increased inflammation and forms of pathology found in the brain tissue of older individuals. In mice, clearance of microglia can be efficiently achieved and leads to a rapid […]

The microenvironment of breast cancer in three dimensions

Cancerous tumors thrive on blood, extending their roots deep into the fabric of the tissue around them. They alter the genetics of surrounding cells and evolve to avoid the protective attacks of immune cells. Now, Penn State researchers have developed a way to study the relationship between solid, difficult-to-treat tumors and the […]

How plants leave behind their parents’ genomic baggage

Passing down a healthy genome is a critical part of creating viable offspring. But what happens when you have harmful modifications in your genome that you don’t want to pass down? Baby plants have evolved a method to wipe the slate clean and reinstall only the modifications that they need to grow […]

Pioneering dementia scanner set to be rolled out across Wales

It comes after a successful pilot between Cardiff University’s Wales Research and Diagnostic PET Imaging Centre at the University Hospital of Wales, Aneurin Bevan University Health Board and the Royal College of Psychiatrists in Wales. From this week the technology will be available across all health boards – and it is hoped […]

Researchers grow mini-organs to study brain development and disease

“Organoids.” It’s a word that has a science-fiction sound to it, but, in fact, organoids are at the core of what scientist Jeff Wrana calls “revolutionizing biology.” That’s because organoids offer the promise of new treatments for a host of diseases and conditions, from inflammatory bowel disease to autism spectrum disorder. “An […]

Getting to the Root of Alzheimer’s

Harvard Medical School researchers at Massachusetts General Hospital have discovered how amyloid-beta—the neurotoxin believed to be at the root of Alzheimer’s disease—forms in axons and related structures that connect neurons in the brain, where it causes the most damage. Their findings, published in Cell Reports, could serve as a guidepost for […]

Rogue antibodies wreak havoc in severe COVID-19 cases

The development of antibodies to the COVID-19 virus has been the great long-term hope of ending the pandemic. However, immune system turncoats are also major culprits in severe cases of COVID-19, Yale scientists report in the journal Nature. These autoantibodies target and react with a person’s tissues or organs similar to […]
