Medical Xpress / Turning up the volume on macrophage-driven immune responses
As part of the body's first line of defense against foreign invaders, macrophages play an integral role in the innate immune system. However, the ability of macrophages to interpret and respond to diverse danger signals remains ...
Medical Xpress / Chronic bowel disease involves multiple types of inflammation happening at once, study reveals
Chronic immune diseases are shaped by multiple inflammatory processes happening at the same time, each in different parts of the tissue. This finding from Karolinska Institutet, published in the journal Immunity, is based ...
Phys.org / Genetic 'bonus material' boosts gut bacterium's oxygen tolerance up to 1,000-fold
The bacterium Segatella copri is one of the most common inhabitants of the human gut. In their latest study, researchers at the Helmholtz Centre for Infection Research (HZI) have discovered that some strains of this bacterial ...
Science X / An ancient quantum machine controls our immune system—and researchers just discovered how it works
Our immune system is much older than we think. Long before dinosaurs existed, early life forms had developed a powerful defense system. Innate immunity has existed since the Cambrian period—that is, since the time when almost ...
Medical Xpress / Blood-brain barrier scans could personalize stroke care using existing MRI data
When a person first exhibits signs of having a stroke, the timing of treatment is critical to restore blood flow to the brain and support recovery. In addition to studying and implementing ways to treat patients faster, investigators ...
Phys.org / On the ground or in the atmosphere? Swarm satellites help characterize and pinpoint destructive events
When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating ...
Phys.org / Symmetry says these crystal vibrations can never mix, but an exotic quantum phase rewrites the rules
Symmetry is one of the most fundamental principles in nature. It describes the rules that make an object look unchanged after a rotation, reflection, or other transformations. In materials, symmetry governs how atoms and ...
Tech Xplore / Canvas system is online after a cyberattack disrupted thousands of schools
Tens of thousands of students studying for final exams around the world Friday regained access to a key online learning system after a cyberattack had earlier knocked it offline, throwing schools and universities into turmoil.
Medical Xpress / New GlyT2 blocker relieves chronic neuropathic pain without major side effects
Chronic neuropathic pain remains one of the most challenging conditions to treat, with current therapies offering limited benefit and being over-reliant on opioids. Researchers at Rensselaer Polytechnic Institute (RPI), along ...
Phys.org / Planet 9 volunteers double known population of brown dwarfs
A new paper from NASA's Backyard Worlds: Planet 9 project announces that volunteers have essentially doubled the number of known brown dwarfs, with over 3,000 new discoveries made over the past 10 years since the project ...
Phys.org / 'Not just hot water': Marine heat waves can create toxic relationship between seagrasses and microbes
Heat stress from marine heat waves can create a toxic relationship between seagrasses and a hidden ecosystem of bacteria, transforming a previously beneficial co-existence between marine plants and microbes into a harmful ...
Medical Xpress / Blood test reveals nine tumor cell 'neighborhoods' tied to immunotherapy outcomes
A simple blood test can reveal the geographic relationships among healthy cells surrounding a cancerous tumor, researchers at Stanford Medicine and the Mayo Clinic have found. The test is the first noninvasive way to study ...
