Linking bacterial populations with health

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

The biggest source of variability in the microbiome is the person-to-person variability. It’s a problem if you’re looking for causality. That’s a red flag word for us – causality – meaning something about the bacterial community causes some disease. You actually don’t know whether it’s the bacteria or whether the bacteria are a sign of something that happened before. It’s very much individualized, so everybody’s history matters.


We are all teeming with bacteria that help us digest food or fight disease, but two people might play host to a very different array of bacteria due to diet, where they live, hobbies or even medical histories.

As a result, scientists have struggled to understand which bacteria are linked to disease and which protect against it. Studies comparing people’s bacterial companions – known as the microbiome – to explore what that variation means might disagree because they analyzed different groups or didn’t sample enough people.

Nitrogen-fixing trees ‘eat’ rocks, play pivotal role in forest health

Posted by in categories: food, health

By tapping nutrients from bedrock, red alder trees play a key role in healthy forest ecosystems, according to a new study.

The study published today in the journal Proceedings of the National Academy of Sciences.

Researchers from Oregon State University and the U.S. Geological Survey determined red alder, through its with -fixing bacteria, taps nutrients that are locked in bedrock, such as calcium and phosphorus. This process accelerates rock dissolution, releasing more mineral nutrients that allow plants and to grow.

A systematic study of microdosing psychedelics

Posted by in categories: climatology, health, law, neuroscience

The phenomenon of ‘microdosing’, that is, regular ingestion of very small quantities of psychedelic substances, has seen a rapid explosion of popularity in recent years. Individuals who microdose report minimal acute effects from these substances yet claim a range of long-term general health and wellbeing benefits. There have been no published empirical studies of microdosing and the current legal and bureaucratic climate makes direct empirical investigation of the effects of psychedelics difficult. In Study One we conducted a systematic, observational investigation of individuals who microdose. We tracked the experiences of 98 microdosing participants, who provided daily ratings of psychological functioning over a six week period. 63 of these additionally completed a battery of psychometric measures tapping mood, attention, wellbeing, mystical experiences, personality, creativity, and sense of agency, at baseline and at completion of the study. Analyses of daily ratings revealed a general increase in reported psychological functioning across all measures on dosing days but limited evidence of residual effects on following days. Analyses of pre and post study measures revealed reductions in reported levels of depression and stress; lower levels of distractibility; increased absorption; and increased neuroticism. To better understand these findings, in Study Two we investigated pre-existing beliefs and expectations about the effects of microdosing in a sample of 263 naïve and experienced microdosers, so as to gauge expectancy bias. All participants believed that microdosing would have large and wide-ranging benefits in contrast to the limited outcomes reported by actual microdosers. Notably, the effects believed most likely to change were unrelated to the observed pattern of reported outcomes. The current results suggest that dose controlled empirical research on the impacts of microdosing on mental health and attentional capabilities are needed.

Rwanda Has Just Completed Over 10,000 Deliveries of Health Supplies Via Medical Drones

Posted by in categories: biotech/medical, drones, health

Rwanda’s advancements on the technological front have been dazzling, with that enviable touch of innovation. Ever since deliveries of health supplies through drones commenced in 2016, the stats have been phenomenal.

To date, over 10,000 health supply deliveries have been completed and this is such a huge feat. Medical drones were launched in October 2016, in partnership with #Zipline Inc. Rwanda is the first country on the continent, and in the world to have such services in the health sector. Such monumental success easily makes Rwanda’s healthcare system among the best in Africa.

Poll: Two Thirds of Americans Support Human Gene Editing to Cure Disease

Posted by in categories: bioengineering, biotech/medical, government, health

Questions about using technologies like CRISPR to gene edit human embryos gained immediacy last month, when Chinese scientists claimed to have edited the genes of two babies in order to protect them against HIV — a move that prompted an international outcry, but also questions about when the technology will be ready for human testing.

“People appear to realize there’s a major question of how we should oversee and monitor use of this technology if and when it becomes available,” Columbia University bioethicist Robert Klitzman told the AP of the new research. “What is safe enough? And who will determine that? The government? Or clinicians who say, ‘Look, we did it in Country X a few times and it seems to be effective.

Boosting Cellular Housekeeping with Exercise and Fasting

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

In order to remain healthy and functional, cells have a number of maintenance systems that help them to dispose of metabolic waste and unwanted proteins. Autophagy is perhaps the best-known example of how cells purge their waste, and another is the ubiquitin-proteasome system (UPS). Researchers are working on ways to boost the activity of the UPS to improve cellular health.

The ubiquitin-proteasome system

During normal cellular function, proteins being constructed in the cell can sometimes become misfolded and start to accumulate over time, which can cause the cell to become dysfunctional and encourage diseases such as Alzheimer’s to develop as the system gums up with bent and broken proteins.
