Pathogenic gut bacteria linked to weight loss from low-calorie diet

Posted by in categories: biotech/medical, food

The same bacteria that cause inflammation also trigger weight loss.


A new study investigating how a low-calorie diet alters gut microbial populations is reporting unexpected results. The findings reveal a strange relationship between extreme caloric restriction and increased levels of a pathogenic bacteria linked to inflammatory bowel disease.

The research began by recruiting 80 overweight or obese subjects. Half the cohort were directed to maintain a stable weight for 16 weeks, while the other half completed a medically supervised weight-loss program including eight weeks of a very low calorie diet (800 kcal per day).

Growing food with air and solar power: More efficient than planting crops

Posted by in categories: biotech/medical, food, solar power

A team of researchers from the Max Planck Institute of Molecular Plant Physiology, the University of Naples Federico II, the Weizmann Institute of Science and the Porter School of the Environment and Earth Sciences has found that making food from air would be far more efficient than growing crops. In their paper published in Proceedings of the National Academy of Sciences, the group describes their analysis and comparison of the efficiency of growing crops (soybeans) and using a food-from-air technique.

For several years, researchers around the world have been looking into the idea of growing “ from air,” combining a renewable fuel resource with carbon from the air to create food for a type of bacteria that create edible protein. One such project is Solar Foods in Finland, where researchers have the goal of building a demonstration plant by 2023. In this new effort, the researchers sought to compare the efficiency of growing a staple crop, soybeans, with growing food from air.

To make their comparisons, the researchers used a food-from-air system that uses solar energy panels to make electricity, which is combined with from the air to produce food for microbes grown in a bioreactor. The protein the microbes produce is then treated to remove and then dried to produce a powder suitable for consumption by humans and animals.

Brain imaging study shows defining traits are forged the moment were born

Posted by in categories: food, neuroscience

There are still many unsolved mysteries about the human brain and its development. Now, a novel study published in Frontiers in Psychiatry sheds new light on the neurobiological origins of our individual traits.

Functional connectivity is the coordinated activity – activation or deactivation – through time between separate brain regions, regardless of their physical closeness or the type of neural connections between them. Changes in functional connectivity can be a sign of mental health disorders such as depression, eating disorders, and schizophrenia, and are thought to have developmental origins.

Biologists Raise Alarm: Brain Damage Caused by Even Small Amounts of Plasticizers

Posted by in categories: food, health, neuroscience

The plasticizers contained in many everyday objects can impair important brain functions in humans. Biologists from the University of Bayreuth warn of this danger in an article in Communications Biology. Their study shows that even small amounts of the plasticizers bisphenol A and bisphenol S disrupt the transmission of signals between nerve cells in the brains of fish. The researchers consider it very likely that similar interference can also occur in the brains of adult humans. They, therefore, call for the rapid development of alternative plasticizers that do not pose a risk to the central nervous system.

Bisphenols are plasticizers that are found in a large number of plastic products worldwide — for example, in food packaging, plastic tableware, drinking bottles, toys, tooth fillings, and babies’ dummies. In recent years, numerous health risks have already been associated with them, especially with bisphenol A (BPA). The Bayreuth research team led by Dr. Peter Machnik at the Animal Physiology research group (led by Prof. Dr. Stefan Schuster) has now for the first time investigated the effects of plasticizers on signal transmission between nerve cells in the adult brain. The study covers not only BPA, but also bisphenol S (BPS), which is often considered less harmful to health. Their findings: Both plasticizers impair communication between the nerve cells of the brain.

Cells optimized to improve healthy ageing compound

Posted by in categories: biotech/medical, chemistry, engineering, food, life extension, neuroscience

The population on Earth is increasingly growing and people are expected to live longer in the future. Thus, better and more reliable therapies to treat human diseases such as Alzheimer’s and cardiovascular diseases are crucial. To cope with the challenge of ensuring healthy aging, a group of international scientists investigated the potential of biosynthesising several polyamines and polyamines analogs with already known functionalities in treating and preventing age-related diseases.

One of the most interesting molecules to study was spermidine, which is a natural product already present in people’s blood and an inducer of autophagy that is an essential cellular process for clearing damaged proteins, e.g., misfolded proteins in brain cells that can cause Alzheimer’s. When people get older the level of spermidine in the blood decrease and dietary supplements, or certain are needed to maintain a stable and high level of spermidine in the blood. However, those products are difficult to produce with traditional chemistry due to their structural complexity and extraction of natural resources is neither a commercially viable nor a sustainable approach.

Therefore, the researchers instead decided to open their biochemical toolbox and use classical metabolic engineering strategies to engineer the yeast metabolism to produce polyamines and polyamines analogs.
