I Edited Human DNA at Home With a DIY CRISPR Kit

Posted by in categories: bioengineering, biotech/medical, genetics

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

You may know Jo Zayner, a โ€œbiohackerโ€ who has been in the vanguard of scientific self-experimentation for years, from their role in Netflixโ€™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.

European farms mix things up to guard against food-supply shocks

Posted by in categories: biotech/medical, climatology, economics, sustainability

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

โ€œItems in this section have limited availability due to supplier production issues,โ€ โ€œSorry, temporarily out of stockโ€ and โ€œSold outโ€ 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.

A new AI-powered gene-editing technique could be set to replace CRISPR

Posted by in categories: biotech/medical, genetics, robotics/AI

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 โ€œworldโ€™s firstโ€ simple, modifiable proteins. Called โ€œzinc fingers,โ€ these special proteins were developed partially through artificial intelligence.

Scientists find a drug that treats obesity, fatty liver, heart disease

Posted by in categories: biotech/medical, food, neuroscience

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 60โ€”long past menopauseโ€”are considered obese. A recent Johns Hopkins study showed that a drug first developed to treat Alzheimerโ€™s disease, schizophrenia, and sickle cell disease could treat obesity and fatty liver and improve heart functionโ€”without changes in food intake or daily activity.

Scientists reversed aging in mice: Is it possible in humans?

Posted by in categories: biotech/medical, genetics, life extension

Researchers from Harvard Medical School found that it is the changes that affect the expression of the DNA โ€” called epigenetics โ€” that affect aging. The discovery may pave the way for more insights into how humans age.

PET imaging shows greater lung inflammation in e-cigarette users than cigarette smokers

Posted by in category: biotech/medical

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.
