Science And Technology: “3D Printing With Living Organisms” (MIT Video)

A method for printing 3D objects that can control living organisms in predicable ways has been developed by an interdisciplinary team of researchers at MIT and elsewhere. This technique may lead to 3D printing of biomedical tools that can be customized to fit the physical body and biomarkers of its users.

Research: Scientists Find Protein To Regulate Immune Attacks, Reduce Rheumatoid Arthritis

From a New Atlas online article:

1200px-Karolinska_Institutet_seal.svgScientists have just discovered a new mechanism that can be key in regulating these immune attacks, raising new hopes of drugs that can protect against joint inflammation and the ailments it can bring.

Through the use of the CRISPR gene-editing tool, the Karolinska Institutet scientists have now shed further light on the role they play in inflammation. The technology enabled the team to make adjustments to a set of hand-picked immune cell genes as a way of learning how those tweaks can impact the behavior of the cells.

“The results we obtained using CRISPR were key to quickly understanding how the system under study is regulated,” says Dr Wermeling. “I have high hopes that the experimental use of CRISPR will be hugely important to our understanding of how immune-cell behavior is regulated, and that this can guide us in the development of new efficacious drugs.”

Nature & Science: Making Flowers Of Food Plants More Attractive To Insect Pollinators (Cambridge)

A rising world population means we’ll need more food in the coming years. But much of our food relies on insect pollination, and insects are in decline around the world. Can we make flowers better at being pollinated, to help solve this problem?

Top New Science Podcasts: Lack Of Clinical Trial Reporting, Gut Microbe Links To Chronic Disease

Science Magazine PodcastsThough a law requiring clinical trial results reporting has been on the books for decades, many researchers have been slow to comply. Now, 2 years after the law was sharpened with higher penalties for noncompliance, investigative correspondent Charles Piller took a look at the results. He talks with host Sarah Crespi about the investigation and a surprising lack of compliance and enforcement.

Also this week, Sarah talks with Brett Finlay, a microbiologist at the University Of British Columbia, Vancouver, about an Insight in this week’s issue that aims to connect the dots between noncommunicable diseases like heart disease, diabetes, and cancer and the microbes that live in our guts. Could these diseases actually spread through our microbiomes?

Study: “Probiotic Drink” Developed That Thwarts Antibiotic Resistance

From a Genetic Engineering & Biotechnology News online article:

Genetic Engineering & Biotechnology News logo“We were able to show that if you can stop the plasmid from replicating, then most of the bacteria lose the plasmid as the bacteria grow and divide. This means that infections that might otherwise be hard to control, even with the most powerful antibiotics available, are more likely to be treatable with standard antibiotics.”

journal.pone.0225202.g001
Fig 1. Anticipated exploitation of pCURE as a probiotic treatment for at-risk individuals. Before treatment, plasmids carrying antibiotic resistance genes are shown as purple circles. After treatment, target plasmids are replaced by pCURE (green circle) which could be engineered to later “self-destruct”. Note that not all gut bacteria carry resistance plasmids but pCURE can enter all Enterobacteriaceae as well as other bacteria. Reduced resistance levels in the gut decrease the chance of treatment failure when infections elsewhere in the body (eg lungs or urinary tract) arise from gut bacteria.

 

Researchers headed by a team at the University of Birmingham in the U.K. have developed a probiotic drink containing genetic elements that are designed to thwart antimicrobial resistance (AMR) in gut bacteria at the genetic level. The drink targets small DNA elements called plasmids that carry antibiotic resistance genes, and which are able to replicate independently and spread between bacteria. By preventing these plasmids from replicating, the antibiotic resistance genes are displaced, effectively resensitizing the bacteria to antibiotics.

Weather Science: NASA Launches “IMPACTS” Campaign To Study East Coast Winter Storms

This winter, NASA is sending a team of scientists, a host of ground instruments, and two research aircraft to study the inner workings of snow storms. The Investigation of Microphysics Precipitation for Atlantic Coast-Threatening Snowstorms, or IMPACTS, field campaign will be the first comprehensive study of East Coast snowstorms in 30 years.
