Stop politicizing origin tracing of COVID-19

Stop politicizing origin tracing of COVID-19 Today 06:38 am JST Today | 07:31 am JST SINGAPORE COVID-19 has become one of the deadliest pandemics in human history and is still evolving. As of June, it has reportedly infected nearly 180 million people and caused around 4 million deaths. Moreover, the pandemic has resulted in significant social and economic disruption globally and triggered political distrust and tensions among countries. It is necessary and important for us to find out the origins of the COVID-19 virus, but the origin tracing should be a scientific issue rather than a geopolitical game. First, the joint WHO-China investigation should be respected. The COVID-19 virus was first publicly reported in December 2019 in Wuhan, China, but that does not necessarily mean China must be the origin of the virus. As we know, the first patient of the acquired immunodeficiency syndrome (AIDS) epidemic was identified in the United States in 1981, but scient

Healthy planet, healthy people: How climate change impacts human immunology

Bethesda, MD Dr. Collman serves as acting deputy director of the National Institute of Environmental Health Sciences (NIEHS) at the U.S. National Institutes of Health (NIH). Prior to that, for the past 11 years, she has been an active member of the NIEHS executive leadership team in her role as director of the NIEHS Division of Extramural Research and Training (DERT). She led the implementation of many exciting scientific programs with partners from NIH institutes and centers, and other federal agencies. Dr. Collman has directed scientific activities across the field of environmental health sciences, including basic sciences organ-specific toxicology, public health-related programs, and training and career development. She also oversees the implementation of the Superfund Research Program and the Worker Education and Training Program. She is credited with building the NIEHS grant portfolio in environmental and molecular epidemiology, and she has also developed several complex multi

Scientists may need to rework on genes that control ageing: NIH

INDIA New England News The study suggests scientists may need to rethink which genes actually control ageing. To understand, the researchers fed fruit flies with antibiotics and monitored the lifetime activity of hundreds of genes that scientists have traditionally thought control ageing. To their surprise, the antibiotics not only extended the lives of the flies but also dramatically changed the activity of many of these genes. Their results suggested that only about 30 per cent of the genes traditionally associated with ageing set an animal’s internal clock while the rest reflect the body’s response to bacteria. “For decades, scientists have been developing a hit list of common ageing genes. These genes are thought to control the aging process throughout the animal kingdom, from worms to mice to humans,” said Edward Giniger, from the NIH’s National Institute of Neurological Disorders and Stroke (NINDS).
