I never thought I’d order live human kidney cells to my address, but that all changed when I found out about biohacker Jo Zayner’s at-home genetic engineering class.

You may know Jo Zayner, a “biohacker” who has been in the vanguard of scientific self-experimentation for years, from their role in Netflix’s 2019 docuseries Unnatural Selection. The series shows Zayner attempting to edit their DNA by injecting themselves with CRISPR, a gene-editing technology. The action inspired a firestorm of criticism.

Zayner is also known for a variety of other bold moves, such as claiming to create a DIY at-home COVID vaccine in 2020 and executing their own fecal microbiome transplant.

Greater diversification could help agriculture withstand climate, economic and geopolitical crises.

“Items in this section have limited availability due to supplier production issues,” “Sorry, temporarily out of stock” and “Sold out” are all signs that became familiar as recent global upheavals exposed how precarious our food supply is.

The COVID-19 pandemic led to bare shelves in supermarkets as shipping routes were cut off. The war in Ukraine has affected the supply of essential grains.

CRISPR may be in for a fight thanks to this new, faster, safer, AI-powered zinc-finger gene-editing technique.

A new study has developed what the researchers call the “world’s first” simple, modifiable proteins. Called “zinc fingers,” these special proteins were developed partially through artificial intelligence.

Scientists from the University of Toronto and the NYU Grossman School of Medicine came up with the method, which is expected to speed up the development of gene therapies. This could be a game-changer for how doctors treat DNA mistakes that happen over time. This is partly because our genes change naturally as we age, which makes it inevitable that mistakes will happen. Or, of course, from genetic disorders inherited at birth.

According to the U.S. Centers for Disease Control and Prevention, more than 40% of people living in the U.S. are obese; and 43% of American women over the age of 60—long past menopause—are considered obese. A recent Johns Hopkins study showed that a drug first developed to treat Alzheimer’s disease, schizophrenia, and sickle cell disease could treat obesity and fatty liver and improve heart function—without changes in food intake or daily activity.

Electronic cigarette (e-cigarette) users have greater lung inflammation than cigarette smokers and non-smokers, according to a new study published online in The Journal of Nuclear Medicine. This study is the first to provide evidence that vaping e-liquids with e-cigarettes creates a unique inflammatory response in the lungs that is different from cigarette smoking.

E-cigarette usage has increased dramatically in the past several years, particularly among adolescents and young adults. While many people assume that e-cigarettes are safer than conventional cigarettes, e-cigarettes can cause pulmonary and increase the risk of lung disease. In addition, their long-term safety has not been rigorously evaluated.

This is the first PET study to use a novel radiotracer, 18 F-NOS, to compare lung inflammation between cigarette and users in vivo. Although PET imaging with 18 F-FDG has been used in the past to investigate inflammation in smokers and vapers, its conclusions were limited.

A monoclonal antibody treatment was found to be safe, well tolerated, and effective in protecting against malaria in a small group of healthy volunteers who were exposed to malaria in a challenge study, according to new research published in The Lancet Infectious Diseases by researchers at the University of Maryland School of Medicine (UMSOM).

“The study demonstrates the feasibility of using monoclonal antibody therapies to help prevent malarial infection and holds promise for deployment to places where the disease is endemic,” said Kirsten Lyke, MD, Professor of Medicine and Director of the Malaria Vaccine and Challenge Unit in the Center for Vaccine Development and Global Health (CVD) at UMSOM. “This may allow us to revisit eradication efforts.”

There were 241 million malaria cases and 627,000 deaths reported worldwide in 2020 alone, which is a 12 percent increase from 2019. Public health experts contend new strategies are urgently needed to achieve the United Nation’s sustainable development goal of 90 percent reduction in malaria incidence and mortality by 2030. Scientists have tried for decades to develop a highly effective malaria vaccine without much success.

A novel virus, potentially fatal to whales and dolphins, has been discovered by researchers at the University of Hawaiʻi Health and Stranding Lab. Prior to its discovery in 10 whale and dolphin host species across the Pacific, the virus was found in only a single marine mammal worldwide, a Longman’s beaked whale stranded on Maui in 2010. The findings are published in Frontiers in Marine Science.

The discovery of beaked whale circovirus (BWCV) in and expands the knowledge of marine mammal species that can become infected with the disease. Circoviruses are DNA viruses that cause disease in birds, pigs and dogs, and in severe cases can become fatal.

“Our study found Cuvier’s beaked whales tested positive for BWCV in Saipan and American Samoa, nearly 4,000 miles away from the first discovered case,” said Kristi West, director of the UH Health and Stranding Lab. “The positive cases found outside of Hawaiʻi were surprising, and indicates that this is spread across the Central and Western Pacific and may have a global presence in marine mammals.”
