24/04/2017A new study has made a major new discovery towards finding the cause of multiple sclerosis (MS), potentially paving the way for research to investigate new treatments. Ahead of MS Awareness Week an international team has discovered a new cellular mechanism that may cause the disease, and a potential hallmark that may be a target for future treatment of the autoimmune disorder.
12/04/2017Scientists at The Scripps Research Institute (TSRI) have found a way to tether HIV-fighting antibodies to immune cells, creating a cell population resistant to the virus. Their experiments under lab conditions show that these resistant cells can quickly replace diseased cells, potentially curing the disease in a person with HIV.
11/04/2017An international team of researchers has proposed an explanation of the way bacteria process external signals. By identifying the detailed structure of the protein complex used by bacteria, the scientists gained insights into the ability of these microorganisms to detect even small changes in the environment and adapt to them. The research findings were published in "Scientific Reports".
07/04/2017The human body is made up of trillions of cells, microscopic computers that carry out complex behaviors according to the signals they receive from each other and their environment. Synthetic biologists engineer living cells to control how they behave by converting their genes into programmable circuits.
28/03/2017Proteins are the molecular all-rounders in our cells. If they do not work properly, severe diseases, such as Alzheimer’s, may result. To develop methods to repair malfunctioning proteins, their structure has to be known. Using a big data approach, researchers of Karlsruhe Institute of Technology (KIT) have now developed a method to predict protein structures.
27/03/2017To fight cancer, every year thousands of chemical substances are screened for their potential effects on tumor cells. Once a compound able to inhibit cancer cell growth is found, it still takes several years of research until the drug gets approved and can be applied to patients.
23/03/2017Scientists from the Florida campus of The Scripps Research Institute (TSRI) have developed a new drug delivery method that produces strong results in treating cancers in animal models, including some hard-to-treat solid and liquid tumors.
22/03/2017A study led by Indiana University School of Medicine researchers demonstrates how electroacupuncture triggers a neurological mechanism that can help promote tissue repair and relieve injury-induced pain.
15/03/2017Researchers at Hiroshima University have developed a smart genetic reference library for locating and weeding out disease-causing mutations in populations.
06/03/2017What makes a cluster of cells become a liver, or a muscle? How do our genes give rise to proteins, proteins to cells, and cells to tissues and organs? The incredible complexity of how these biological systems interact boggles the mind - and drives the work of biomedical scientists around the world.
01/03/2017Our blood stem cells generate around a thousand billion new blood cells every day. But the blood stem cells’ capacity to produce blood changes as we age. This leads to older people being more susceptible to anaemia, lowered immunity and a greater risk of developing certain kinds of blood cancer.
01/03/2017For the first time ever, a single flexible fiber no bigger than a human hair has successfully delivered a combination of optical, electrical, and chemical signals back and forth into the brain, putting into practice an idea first proposed two years ago.
27/02/2017Diabetes is a leading cause of kidney disease, a serious, often fatal complication that is difficult to diagnose in early, potentially treatable stages. Now, a research team at the Icahn School of Medicine at Mount Sinai has revealed biological pathways involved in diabetic kidney disease, providing hope that both early diagnostic tests and targeted treatment can be designed.
15/02/2017A few days after a viral infection, countless killer cells swarm out to track down and kill infected body cells. In this way, they are highly effective at preventing pathogens from being able to spread further. An international research team has now explained an important mechanism behind building this army. The work under the aegis of the University of Bonn is published in the journal Immunity.
10/02/2017Roasted and salted, ground as a baking ingredient or fresh from the shell - for all those who enjoy eating nuts, there is good news from nutritionists at Friedrich Schiller University Jena (Germany). Their latest research shows that nuts can inhibit the growth of cancer cells.
10/02/2017The use of nanoparticles - small, virus-sized elements developed under laboratory conditions - is increasingly widespread in the world of biomedicine. This rapidly-evolving technology offers hope for many medical applications, whether for diagnosis or therapies.
06/02/2017Which molecular mechanisms are at work when, in the case of inflammation, immune cells migrate from the blood vessel into the tissue? Researchers at the Cells-in-Motion Cluster of Excellence at Münster University have gained new insights into this question. The study has been published in the journal Cell Reports.
