Immune system protein may defend against deadly intestinal disease in babies

The intestinal disease necrotizing enterocolitis is a leading cause of death among premature infants born in the U.S. and across the globe. Characterized by excessive inflammation that can cause tissue decay in the bowels, the disease provides a pathway for infectious and deadly bacteria to enter the bloodstream. Despite four decades of research, effective treatments remain elusive, and mortality rates […]

New neuroelectronic system can read and modify brain circuits

As researchers learn more about the brain, it has become clear that responsive neurostimulation is becoming increasingly effective at probing neural circuit function and treating neuropsychiatric disorders, such as epilepsy and Parkinson’s disease. But current approaches to designing a fully implantable and biocompatible device able to make such interventions have major limitations: their resolution isn’t high enough and most require […]

No, vaccine side effects don’t tell you how well your immune system will protect you from COVID-19

If someone gets a headache or feels a bit under the weather after receiving a COVID-19 vaccine, it’s become common to hear them say something like “Oh, it just means my immune system is really working hard.” On the flip side, when people don’t notice any side effects, they sometimes worry the shot isn’t doing its job or their immune […]

Strains show in Australia’s ‘gold standard’ quarantine system

New coronavirus variants are forcing Australia and New Zealand to rethink already-stringent quarantine rules for overseas visitors, even as their systems are replicated around the world. Officials in Australia’s Victoria state on Wednesday became the latest to warn that the spread of the UK, Brazilian and South African mutations mean its 14-day mandatory quarantine must be toughened. “These hyper infectious […]

Human immune cells have natural alarm system against HIV

Treatment for HIV has improved tremendously over the past 30 years; once a death sentence, the disease is now a manageable lifelong condition in many parts of the world. Life expectancy is about the same as that of individuals without HIV, though patients must adhere to a strict regimen of daily antiretroviral therapy, or the virus will come out of […]

A new way to help the immune system fight back against cancer

Scientists at the University of Wisconsin School of Medicine and Public Health are breaking new ground to make cancer cells more susceptible to attack by the body’s own immune system. Working in mice, a team led by Jamey Weichert, professor of radiology, and Zachary Morris, professor of human oncology, is combining two different techniques in its approach, using targeted radionuclide […]

The best COVID warning system? Poop and pooled spit, CSU says – The Denver Post

By Rae Ellen Bichell, Kaiser Health News Carol Wilusz’s mornings now often start at 4 a.m., scanning the contents of undergraduates’ feces. Specifically, scanning the data on how much coronavirus they flushed into the shadows, destined to be extracted from 17 manholes connected to dorm buildings on Colorado State University’s Fort Collins campus. “There are quite extensive numbers of poop […]

RNA quality control system goes awry in frontotemporal lobar degeneration

Researchers at Osaka University have identified a fault in the RNA quality control system of cells that leads to the haywire production of toxic proteins in frontotemporal lobar degeneration and amyotrophic lateral sclerosis (FTLD/ALS). Their new study, published in the EMBO Journal, shows that an abnormality of the C9orf72 gene produces toxic proteins that hinder the cells’ ability to destroy […]
