Scientists Puzzled as James Webb Detects Signal From Completely Empty Void in Space - Futurism

A USask mouse study combining endotoxin and glyphosate exposure found lung changes only synchrotron imaging could detect A University of Saskatchewan (USask) study has found that combined exposure to two common agricultural contaminants – endotoxin and the herbicide glyphosate – produced lung damage in female mice that standard biomedical testing missed entirely, and that only became visible through synchrotron imaging at the Canadian Light Source (CLS) in Saskatoon. The research, led by Dr. Shelley Kirychuk, director of the Canadian Centre for Rural and Agricultural Health (CCRAH) at USask, was published this year in the journal Scientific Reports.

Scleroderma (systemic sclerosis) is a rare, chronic, autoimmune disease that causes the body to produce too much collagen, leading to the hardening and thickening of the skin and internal organs. For more than 50 years, physicians have relied on manually pinching the skin to assess its thickness, a subjective approach that remains central to the diagnosis of systemic sclerosis, assessment of disease extent and progression, and monitoring of response to treatment. Despite being the accepted standard practice, doctors can score the same patient differently based on their own unique touch and judgement, making it difficult to accurately track changes in skin thickening over time or assess a patient's response to treatment. For the first time, researchers at Boston University Chobanian & Avedisian School of Medicine and the Boston University Department of Biomedical Engineering have developed and tested a camera-based technique called spatial frequency domain imaging (SFDI) to assess skin changes in scleroderma patients. SFDI works by shining patterns of harmless light on the skin, without touching it, and measuring how the light bounces back.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
