An artificial pancreas originally developed at the University of Virginia Center for Diabetes Technology improves blood sugar control in children ages 2 to 6 with type 1 diabetes, according to a new study. Details of the clinical study and its findings have been published in the New England Journal of Medicine.

Trial participants using the artificial pancreas spent approximately three more hours per day in their target blood sugar range compared with participants in a control group who continued relying on the methods they were already using to manage their blood sugar.

The Control-IQ system, manufactured by Tandem Diabetes Care, is a diabetes management device that automatically monitors and regulates blood glucose. The artificial pancreas has an insulin pump that uses advanced control algorithms based on the person’s glucose monitoring information to adjust the insulin dose as needed.

A multi-state study from the U.S. Center for Disease Control and Prevention’s (CDC) VISION Network has found that first-generation COVID-19 mRNA vaccines were associated with protection against COVID-19 during periods of omicron BA.4/BA.5 predominance.

The new analysis found that mRNA vaccines were protective against COVID-19-associated hospitalization and ICU admission or in-hospital death and noted less severe disease during BA.4/BA.5 predominance compared to earlier omicron variants.

During BA.4/BA.5 predominance, estimated 3-dose vaccine effectiveness against hospitalization was 68 percent between 7-and 119-days post-vaccination. Vaccine effectiveness against hospitalization decreased to 36 percent by 120 days or more post-vaccination.

A new study published in Nature reports that a technology known as spatial omics can be used to map simultaneously how genes are switched on and off and how they are expressed in different areas of tissues and organs. This improved technology, developed by researchers at Yale University and Karolinska Institutet, could shed light on the development of tissues, as well as on certain diseases and how to treat them.

Almost all cells in the body have the same set of genes and can in principle become any kind of cell. What distinguishes the cells is how the genes in our DNA are used. In recent years, spatial omics have given us a deeper understanding of how cells read the genome in precise locations in tissues. Now, researchers have further evolved this technology to increase knowledge of how tissues develop and how different diseases arise.

A key part of the study is the researchers’ ability to spatially map simultaneously two crucial components of our genetic makeup, the epigenome and the transcriptome. The epigenome controls the switching mechanisms that turn genes on and off in individual cells, whereas the transcriptome is the result of those gene expressions and what makes each cell unique.

Following a Mediterranean diet may lower the risk for memory and thinking problems in people with multiple sclerosis (MS), a new study suggests.

Researchers from The University of Queensland have discovered the active compound from an edible mushroom that boosts nerve growth and enhances memory.

Professor Frederic Meunier from the Queensland Brain Institute said the team had identified new active compounds from the mushroom, Hericium erinaceus.

“Extracts from these so-called ‘lion’s mane’ mushrooms have been used in traditional medicine in Asian countries for centuries, but we wanted to scientifically determine their potential effect on brain cells,” Professor Meunier said.

Long-term microgravity exposure causes various biological changes, ranging from bone loss to changes in cardiovascular function.

Towards this, SpaceX’s Dragon cargo ship is set to deliver cardiac tissue chips to the International Space Station (ISS). According to NASA, the cargo spacecraft is expected to autonomously dock with the ISS at 7:52 am EDT Thursday, March 16.

Scientists have long known that mitochondria play a crucial role in the metabolism and energy production of cancer cells. However, until now, little was known about the relationship between the structural organization of mitochondrial networks and their functional bioenergetic activity at the level of whole tumors.

In a new study, published in Nature, researchers from the UCLA Jonsson Comprehensive Cancer Center used positron emission tomography (PET) in combination with electron microscopy to generate 3-dimensional ultra-resolution maps of mitochondrial networks in lung tumors of genetically engineered mice.

They categorized the tumors based on mitochondrial activity and other factors using an artificial intelligence technique called deep learning, quantifying the mitochondrial architecture across hundreds of cells and thousands of mitochondria throughout the tumor.

A newly identified disease called Plasticosis is scarring the tissue of seabirds, and probably us as well. Its cause: microplastic pollution.

Plasticosis or Plastic-Induced Fibrotic Disease has been discovered in seabirds caused by ingesting microplastic pollution.

NPL, in collaboration with London Biofoundry and BiologIC Technologies Ltd, have released an analysis on existing and emerging DNA Synthesis technologies in Nature Reviews Chemistry, featuring the work on the front cover.

The study, which was initiated by DSTL, set out to understand the development trajectory of DNA Synthesis as a major industry drive for the UK economy over the next 10 years. The demand for synthetic DNA is growing exponentially. However, our ability to make, or write, DNA lags behind our ability to sequence, or read, it. The study reviewed existing and emerging DNA synthesis technologies developed to close this gene writing gap.

DNA or genes provide a universal tool to engineer and manipulate living systems. Recent progress in DNA synthesis has brought up limitless possibilities in a variety of industry sectors. Engineering biology, therapy and diagnostics, data storage, defense and nanotechnology are all set for unprecedented breakthroughs if DNA can be provided at scale and low cost.
