Administering anti-cancer drugs redefined Researchers from Polytechnique Montréal, Université de Montréal and McGill University have just achieved a spectacular breakthrough in cancer research. They have developed new nanorobotic agents capable of navigating through the bloodstream to administer a drug with precision by specifically targeting the active cancerous cells of tumours. This way of injecting medication […]

Simple Method Developed to Characterize Immune Cells in Tumors

Posted on Leave a commentPosted in Biomedical Science, Cancer, Diagnostics, Genetics, Immune System, Medical News, Microscopy, Pioneering Technology

Despite recent achievements in the development of cancer immunotherapies, only a small group of patients typically respond to them. Predictive markers of disease course and response to immunotherapy are urgently needed. To address this need, researchers at The Tisch Cancer Institute (TCI) at the Icahn School of Medicine at Mount Sinai have developed a new […]

Posted on Leave a commentPosted in Biomedical Science, Biotechnology, Diagnostics, Epidemiology, Immune System, Medical News, Mental Health, Microscopy, Nervous System, Neurology, Parasites, Pioneering Technology, Viruses

The current Zika epidemic is likely to end within three years because there will be too few people left to infect, a team of scientists is predicting. Writing in the journal Science, they said this could lead to a gap of 10 years before the next epidemic. The Imperial College London team created a model […]

Illness: How Bacterial Protective Shell Adapts

Posted on 1 CommentPosted in Antibiotics, Bacteria, Biomedical Science, Medical News, Microscopy, Pharmaceuticals

Researchers at Umeå University in Sweden have published new findings on the adaptation of the bacterial cell wall in the Journal of the American Chemical Society. The study reveals novel bacterial defence mechanisms against the immune system and how they can become resistant to antibiotics. Bacteria are surrounded by a mesh-like structure which, similar to an […]

Researchers at the University of Wisconsin-Madison have confirmed that a benign bacterium called Wolbachia pipientis can completely block transmission of Zika virus in Aedes aegypti, the mosquito species responsible for passing the virus to humans. A strain of Aedes aegypti mosquitos feed from a membrane of blood in Matthew Aliota’s research lab insectary. Credit: Jeff Miller […]

Herpesviruses could be eradicated with gene-editing technique

Posted on Leave a commentPosted in Biomedical Science, Biotechnology, Dermatology, DNA, Genetics, Immune System, Medical News, Microscopy, Pharmaceuticals, Viruses

Herpesviruses are responsible for an array of infections and diseases, including cold sores, shingles, genital herpes, and even some forms of cancer. Now, new research reveals how a revolutionary genome-editing technique called CRISPR/Cas9 could eliminate these viruses once and for all. Researchers say the CRISPR/Cas9 gene-editing tool shows promise for the elimination of herpesviruses. Study […]

Allergy Season – what causes hay fever and how do we treat it?

ACHHOOOO! ‘tis the season to be sneezing folks. But why does the summer cause some of us to have red eyes, a runny nose and constantly sneeze? Allergies can vary from mildly irritating to life threatening. The most common allergy that most people experience is hay fever, or its medical term, Allergic Rhinitis.  During this […]

Research may point to new ways to deliver drugs into bacteria

Posted on Leave a commentPosted in Antibiotics, Bacteria, Biomedical Science, Diagnostics, DNA, Genetics, Immune System, Medical News, Microscopy

An exhaustive look at how bacteria hold their ground and avoid getting pushed around by their environment shows how dozens of genes aid the essential job of protecting cells from popping when tensions run high. For centuries, biologists have considered cells the irreducible unit of life, and cells require various types of envelopes to contain […]

Nanoscale Trojan horses treat inflammation

The superbug that experts have been dreading has just reached the US

Posted on Leave a commentPosted in Antibiotics, Bacteria, Biomedical Science, Diagnostics, DNA, Epidemiology, Genetics, Immune System, Medical News, Microscopy, Pharmaceuticals

A type of bacteria that’s resistant to the last antibiotic we have left against superbugs has made it to the US, and it signals something doctors have been dreading for years – the end for antibiotics. The bacterium, a strain of Escherichia coli, was found in the urine of a Pennsylvania woman. The strain is […]

If you think you’re having a bad day, the following article may cheer you up – count your lucky stars that you don’t have any of the following illnesses. Today’s broadcast will be focusing on the world’s deadliest diseases. Of course there are many diseases that can be considered just as bad as these but […]

‘Kidney-on-a-chip’ could save lives in the ICU

Posted on Leave a commentPosted in Anatomy, Biomedical Science, Biotechnology, Diagnostics, Medical News, Microscopy, Pioneering Technology

Many lifesaving drugs can be dangerously toxic to the kidneys. Because there are a number of factors that change the way kidneys process drugs, it is very difficult to predict how they will affect each patient. Researchers from the University of Michigan have developed a “kidney-on-a-chip” that promises to make testing the effects of drugs […]

Biophysicist finds that rapidly proliferating yeast pack quite a punch: Up to 150 psi When tiny microbes jam up like fans exiting a baseball stadium, they can do some real damage. A wild strain of yeast growing in a tiny chamber gradually fills the space and, because the yeast cells are so sticky, easily clog […]

Space tourism? Why not? See the world as you have never seen it before. With at least 700 people signed up for commercial trips, and scientists figuring out how we can live on Mars, the impossible is becoming real. Are there hazards? Of course. As one researcher puts it: “Space is an unforgiving environment that […]

Silicon ‘nano-balls’ have wiped out metastatic breast cancer in mice

Posted on Leave a commentPosted in Biotechnology, Cancer, Cardiovascular, Medical News, Microscopy, Pharmaceuticals, Pioneering Technology

Human trials could start as early as 2017. Despite all our advances in cancer research, our best strategy of fighting the disease is still brute force, with only a fraction of the drugs administered actually reaching the tumour cells, and most being absorbed into healthy tissue. When cancer spreads, the likelihood of medication reaching it […]

Scientists look for new antibiotic drugs in unexpected places

Posted on Leave a commentPosted in Antibiotics, Bacteria, Biomedical Science, Immune System, Medical News, Microscopy, Pharmaceuticals

Many of the drugs we use in hospitals – antibiotics, antifungals and anti-cancer drugs, to name but a few – are produced by bacteria that live in the soil beneath our feet. Most of the antibiotics we use were discovered by scientists in the mid-20th century, but as the threat of drug resistant infections increases, […]
