Health Highlight: Natural Metabolite Might Reset Aging Biological Clocks

Polyamides linked to aging

As we age, our biological clocks tend to wind down. A Weizmann Institute research team has now revealed an intriguing new link between a group of metabolites whose levels drop as our cells age and the functioning of our circadian clocks – mechanisms encoded in our genes that keep time to cycles of day and night. Their results, which appeared in Cell Metabolism, suggest that the substance (called polyamides), which is found in many foods, could possibly help keep our internal timekeepers up to speed.

Health Highlight: Researchers use gut bacteria to map genetic mutations in colorectal cancer tumours

Gut bacteria

Colorectal cancer is now understood to be definitely linked to microbial problems in the gut. Research has shown that the disease is linked with less numbers and diversity in the gut microbiome, and with the increased presence of more harmful strains. Therefore using gut bacteria to diagnose and even aid in cancer prevention is highly desirable due to it’s quick, non-invasive ease of investigation.

Now, a study from researchers at University of Minnesota has predicted key genetic mutations in colorectal tumours by analyzing the types of gut bacteria present around them. The team state that it could be possible to genetically classify the colorectal tumour a person has without having to do a biopsy and dissect it. Their findings were presented at the American Society of Human Genetics (ASHG) 2015 Annual Meeting.

Anti-parasite Drugs and the Nobel Prize for Medicine

nobel medal in medicine

The 2015 Nobel Prize in Physiology or Medicine was announced earlier this week [1]. The prize was awarded to three scientists who developed therapies by looking at natural, local substances, against parasitic infections.

The prize of 8-million-Swedish-krona ($1.2-million USD) was divided, with one half jointly to Drs. William C. Campbell, age 85, at Drew University in Madison, New Jersey, USA, and Satoshi Omura, age 80, at Kitasato University in Tokyo, Japan, for their work on a novel therapy against infections caused by roundworm parasites, and the other half to Dr. Youyou Tu, age 85, at the China Academy of Traditional Chinese Medicine in Beijing, China, for her work on a novel therapy against Malaria.

Scientists Hit Limit of Time to Read Scholarly Articles

Scientists may have hit the wall when it comes to reading articles. A 35-year trend of researchers reading an increasing number of scholarly manuscripts appears to be leveling off, accompanied by the bottoming out of time taken to read each article.

Johnson & Johnson to Make Clinical Trial Data Open

In a move that promotes open science, Johnson & Johnson (J&J) announced last week that it will make all of its clinical trial data publicly available.
