The cyber security risks to DNA processing programs

The cyber security risks to DNA processing programs
Rapid improvement in DNA sequencing has sparked a proliferation of medical and genetic tests that promise to reveal everything from one's ancestry to fitness levels to microorganisms that live in your gut. A new study from University of Washington researchers that analysed the security hygiene of common, open-source DNA processing programs finds evidence of poor computer security practices used throughout the field.

The advancement in regenerative medicine we were waiting for

The advancement in regenerative medicine we were waiting for
Researchers at The Ohio State University Wexner Medical Center and Ohio State's College of Engineering have developed a new technology, Tissue Nanotransfection (TNT), that can generate any cell type of interest for treatment within the patient's own body. This technology may be used to repair injured tissue or restore function of aging tissue, including organs, blood vessels and nerve cells.

Sequencing program could enable precision medicine for advanced cancer

Sequencing program could enable precision medicine for advanced cancer
  In one of the largest and most comprehensive efforts to examine the genetic and molecular landscape of advanced cancer, researchers at the University of Michigan Comprehensive Cancer Center sequenced the DNA and RNA of 500 patients with metastatic cancer. The results are published in Nature.

How to reprogram cells in the immune system

How to reprogram cells in the immune system
When the immune system is imbalanced, either due to overly-active cells or cells that suppress its function, it causes a wide range of diseases, from psoriasis to cancer. By manipulating the function of certain immune cells, called T cells, researchers could help restore the system's balance and create new treatments to target these diseases. Scientists at the Gladstone Institutes revealed, for the first time, a method to reprogram specific T cells.

Device detects tumour cells in blood

Device detects tumour cells in blood
Researchers at the URV’s Department of Physical and Inorganic Chemistry, led by the ICREA researcher, Ramon Álvarez Puebla, and the professor of Applied Physics, Francesc Díaz, and the Department of Clinical Oncology of the HM Torrelodones University Hospital, have patented a portable device that can detect tumour cells in blood. The device counts the number of tumour cells in a blood sample in real time and is thus a highly effective tool for improving the monitoring, treatment and diagnosis of cancer.

Stem cell-based therapy targets skin-to-brain cancer

Stem cell-based therapy targets skin-to-brain cancer
Investigators from Brigham and Women's Hospital (BWH) and the Harvard Stem Cell Institute have a potential solution for how to kill tumour cells that have metastasised to the brain. The team has developed cancer-killing viruses that can deliver stem cells via the carotid artery, and applied them to metastatic tumours in the brain of clinically relevant mouse models. The investigators report the elimination of metastatic skin cancer cells from the brain of these preclinical models, resulting in prolonged survival.

Technique can clone thousands of genes at once

Technique can clone thousands of genes at once
Scientists at Johns Hopkins, Rutgers, the University of Trento in Italy, and Harvard Medical School report they have developed a new molecular technique called LASSO cloning, which can be used to isolate thousands of long DNA sequences at the same time, more than ever before possible. The new technology, they say, speeds up the creation of proteins, the final products of genes, and is likely to lead to far more rapid discovery of new medicines and biomarkers for scores of diseases.

Gene communication stimulates regenerative healing

Gene communication stimulates regenerative healing
In a study published in the journal Proceedings of the National Academy of Sciences, the University of Florida researchers found genes known to form hearts cells in humans and other animals in the gut of a muscle-less and heartless sea anemone. But the sea anemone isn't just any sea creature. It has superpower-like abilities: cut it into many pieces and each piece will regenerate into a new animal.

Production of brain cells enables further research

Production of brain cells enables further research
Important pieces of the puzzle to understand what drives diseases such as Alzheimer’s and Parkinson’s are still missing today. One crucial obstacle for researchers is that it is impossible to examine a living brain cell in someone who is affected by the disease. With the help of a new method for cell conversion, researchers at Lund University in Sweden have found a way to produce diseased, aging brain cells on a large scale in a cell culture dish.

Cellular 'guillotine' helps understand how single cells heal

Cellular 'guillotine' helps understand how single cells heal
While doing research at the Woods Hole Marine Biological Laboratory in Massachusetts, Sindy Tang learned of a remarkable organism: Stentor coeruleus. It’s a single-celled, free-living freshwater organism, shaped like a trumpet and big enough to see with the naked eye. And, to Tang’s amazement, if cut in half it can heal itself into two healthy cells. Tang, who is an assistant professor of mechanical engineering at Stanford University, knew right away that she had to study this incredible ability.
