Mining the microbiome: Uncovering new antibiotics inside the human gut      (via sciencedaily.com)     Original source 

Researchers surveyed the gut microbiomes of nearly 2,000 people, discovering dozens of potential new antibiotics. The lead candidate, prevotellin-2, demonstrated anti-infective capabilities on par with polymyxin B, an FDA-approved antibiotic used today to treat multidrug-resistant infections, suggesting that the human gut microbiome may contain antibiotics that will someday find clinical application.

Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia      (via sciencedaily.com)     Original source 

Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.

Zebrafish use surprising strategy to regrow spinal cord      (via sciencedaily.com)     Original source 

A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.

Surprise finding in study of environmental bacteria could advance search for better antibiotics      (via sciencedaily.com)     Original source 

Researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial cell's 'envelope' or enclosure is key to its survival, the finding could advance the search for new and better antibiotics.

A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.

Diet is main risk factor for colon cancer in younger adults, new study suggests      (via sciencedaily.com)     Original source 

A new study has identified diet-derived molecules called metabolites as main drivers of young-onset colorectal cancer risk, especially those associated with red and processed meat. The report, which analyzed metabolite and microbiome datasets, highlighted that one of the best ways a younger (less than 60 years) adult can prevent colorectal cancer is to discuss their diet with their doctor.

New mechanism of action kills cancer cells      (via sciencedaily.com)     Original source 

Conventional cancer drugs work by triggering apoptosis, that is programmed cell death, in tumor cells. However, tumor cells have the ability to develop strategies to escape apoptosis, rendering the drugs ineffective. A research team now describes a new mechanism of action that kills cancer cells through ferroptosis.

C-section antibiotics impact the infant microbiome far less than infant diet      (via sciencedaily.com)     Original source 

Caesarean section recipients are usually given prophylactic antibiotics just before the procedure to prevent later infections at the surgical site. But there have been concerns about whether these antibiotics may have a negative impact on newborns and their microbiomes if the drugs travel through the umbilical cord and reach the baby before the cord is cut. Now, a study has confirmed that although these antibiotics can cause subtle changes to the infant microbiome, they are much less significant than the impact of how the babies are fed.
