Wi-Fi could help Identify when you’re Struggling to Breathe

Wi-Fi could help identify when you're struggling to breathe

Wi-Fi routers continuously broadcast radio frequencies that your phones, tablets and computers pick up and use to get you online. As the invisible frequencies travel, they bounce off or pass through everything around them—the walls, the furniture and even you. Your movements, even breathing, slightly alter the signal’s path from the router to your device.

Those interactions don’t interrupt your internet connection, but they could signal when someone is in trouble...

Found: A Protective Probiotic for ALS

A probiotic bacterium called Lacticaseibacillus rhamnosus HA-114 prevents neurodegeneration in the C. elegans worm, an animal model used to study amyotrophic lateral sclerosis (ALS). That’s the finding of a new study at Canada’s CHUM Research Centre (CRCHUM) led by Université de Montréal neuroscience professor Alex Parker and published in the journal Communications Biology.

He and his team suggest that the disruption of lipid metabolism contributes to this cerebral degeneration, and show that the neuroprotection provided by HA-114, a non-commercial probiotic, is unique compared to other strains of the same bacterial family tested.

“When we add it to the diet of our animal model, we notice that it suppresses the progression of motor neuron degenera...

Scientists from Trinity College Dublin have made an important breakthrough in understanding how inflammation is regulated. They have just discovered that a key immune alarm protein previously believed to calm down the immune response actually does the opposite.

Their work has numerous potential impacts, especially in the context of understanding and responding to autoimmune disorders and inflammation.

While our immune system serves a very important function protecting us from infection and injury, when immune responses become too aggressive this can lead to damaging inflammation, which occurs in conditions such as rheumatoid arthritis and psoriasis...

A photoacoustic sensor could help clinicians diagnose tumors, organ malfunction and more. A team of engineers at the University of California San Diego has developed an electronic patch that can monitor biomolecules in deep tissues, including hemoglobin. This gives medical professionals unprecedented access to crucial information that could help spot life-threatening conditions such as malignant tumors, organ dysfunction, cerebral or gut hemorrhages and more.

“The amount and location of hemoglobin in the body provide critical information about blood perfusion or accumulation in ...
