Scientists identify severe asthma species, show air pollutant as likely contributor

Asthma afflicts more than 300 million people worldwide. The most severe manifestation, known as non-Th2, or non-atopic childhood asthma, represents the majority of the cases, greater than 85%, particularly in low-income countries, according to Hyunok Choi, an associate professor at the Lehigh University College of Health. Yet, whether non-Th2 is a distinct disease (or endotype) […]

Scientists shrink pancreatic tumors by starving their cellular ‘neighbors’

Scientists at Sanford Burnham Prebys Medical Discovery Institute demonstrated for the first time that blocking ‘cell drinking,’ or macropinocytosis, in the thick tissue surrounding a pancreatic tumor slowed tumor growth—providing more evidence that macropinocytosis is a driver of pancreatic cancer growth and is an important therapeutic target. The study was published in Cancer Discovery, a […]

Survivors struggle as scientists race to solve COVID mystery

There was no reason to celebrate on Rachel Van Lear’s anniversary. The same day a global pandemic was declared, she developed symptoms of COVID-19. A year later, she’s still waiting for them to disappear. And for experts to come up with some answers. The Texas woman is one of thousands of self-described long-haulers, patients with […]

Team of bioethicists and scientists suggests revisiting 14-day limit on human embryo

An international team of bioethicists and scientists, led by a researcher at Case Western Reserve University, contends it may be justified to go beyond the standing 14-day limit that restricts how long researchers can study human embryos in a dish. Going beyond this policy limit could lead to potential health and fertility benefits, and the […]

Scientists repair injured spinal cord using patients’ own stem cells

Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers from Yale University and Japan report Feb. 18 in the Journal of Clinical Neurology and Neurosurgery. For more than half of the patients, substantial improvements in key functions—such as ability to walk, […]

UK coronavirus variant found in US could be deadlier, scientists say

Coronavirus variants are ‘something that we all need to be taking seriously’: Dr. Tom Inglesby Dr. Tom Inglesby, Johns Hopkins Center for Health Security director, tells ‘Fox News Sunday’ he is ‘concerned’ about virus mutations. He also discusses the COVID-19 vaccine rollout process. The coronavirus variant that originated in the United Kingdom and has since […]

Scientists switch on tissue repair in inflammatory bowel disease

A method that instructs immune system cells to help repair damaged tissues in the intestine has been developed by researchers at KU Leuven and Seoul National University. This opens the way for more effective treatment of inflammatory bowel disease, including ulcerative colitis and Crohn’s disease. The study was carried out on humans and mice. When […]
