Chemical mixtures pose ‘underestimated’ risk to human health say scientists

Posted by in categories: food, health

This year, the European Union heavily restricted four types of phthalates in consumer products because of their possible health effects. Phthalates are plasticisers, ubiquitous chemicals that soften plastics in many consumer products. They are present in food wrappings, clothes, packaging, car parts, cosmetics and fragrances.

Over time, these plasticisers end up in the air, soil, water, food and household dust. They can also end up in our bodies. This is worrying because they are implicated in reproductive abnormalities in mammals. Studies of people have linked plasticisers to sperm damage, lower fertility, early puberty in girls and thyroid effects. The phthalates will be now legally be restricted to 0.1% in weight in articles used by consumers or in outdoor areas.

But scientists are increasingly concerned not just about single chemicals, which are found in people’s bodies at levels that are usually not toxic, but about what happens to toxicity when these chemicals mix.

Understanding the power of honey through its proteins

Posted by in categories: chemistry, food

Honey is a culinary staple that can be found in kitchens around the world. Its long shelf life and medicinal properties make it a unique, multipurpose natural product. Although it seems that a lot is known about the sweet substance, surprisingly little is known about its proteins. Check out research in the Journal of Natural Products with new data on honey proteins that could lead to new medicinal applications:

Europe abandons plans for ‘flagship’ billion-euro research projects

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

The consortium, called LifeTime, aims to use three emerging technologies—machine learning, the study of single cells, and lab-grown organlike tissues called organoids—to map how human cells change over time and develop diseases. It is one of six candidates in the latest round of ambitious proposals for European flagships, billion-euro research projects intended to run for 10 years. There is just one snag: The European Commission has decided that it won’t launch any of them.

Six candidate research proposals lost in limbo.

Boosting Levels of NAD+ May Make Senescent Cells More Aggressively Inflammatory

Posted by in categories: biotech/medical, life extension

On senescent cells, mechanism of interaction and (potential?!) side effects of NAD+ supplements. “… Those people self-experimenting with NAD+ precursor supplementation should consider keeping a close eye on markers of inflammation…”

Enhancing levels of NAD+ in mitochondria via delivery of various precursor compounds as supplements is growing in popularity as an approach to boost faltering mitochondrial function and thus modestly slow the progression of aging. A human trial demonstrated improved vascular function as a result of nicotinamide riboside supplementation, for example. Researchers here show that increased NAD+ will likely make worse the inflammatory signaling of senescent cells, however. Senescent cells accumulate with age, and are an important cause of the chronic inflammation of aging that drives the progression of many age-related diseases.

The results here suggest that efficient senolytic treatments to selectively destroy senescent cells should proceed any of the current approaches to raising levels of NAD+ in older individuals — and it is an open question as to whether any of the existing available options are efficient enough to make NAD+ enhancement safe in the longer term. Those people self-experimenting with NAD+ precursor supplementation should consider keeping a close eye on markers of inflammation.

For The First Time, Scientists Turn Human Stem Cells Into Insulin-Producing Cells

Posted by in categories: biotech/medical, innovation

May have posted this, but this is very cool. “We can now generate insulin-producing cells that look and act a lot like the pancreatic beta cells you and I have in our bodies,” explains one of the team, microphysiologist Matthias Hebrok from the University of California San Francisco (UCSF).

Although treatment of type 1 diabetes has come a long way since it was first described in Ancient Egypt, insulin injections and finger pricks are a daily part of life for many diabetics.

But researchers have just made a breakthrough that might one day make these technologies obsolete, by transforming human stem cells into functional insulin-producing cells (also known as beta cells) – at least in mice.
