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.
23/01/2017Researchers at University of California San Diego School of Medicine report that elderly women who sit for more than 10 hours a day with low physical activity have cells that are biologically older by eight years compared to women who are less sedentary.
19/01/2017Doctors have found a way to manipulate wounds to heal as regenerated skin rather than scar tissue. The method involves transforming the most common type of cells found in wounds into fat cells - something that was previously thought to be impossible in humans.
17/01/2017As early humans shed the hairy coats of their closest evolutionary ancestors, they also gained a distinct feature that would prove critical to their success: a type of sweat gland that allows the body to cool down quickly. Those tiny glands are enormously useful, allowing us to live in a wide variety of climates, and enabling us to run long distances.
17/01/2017Scientists report in Nature using pluripotent stem cells to generate human stomach tissues in a petri dish that produce acid and digestive enzymes. Publishing their findings online, researchers at Cincinnati Children's Hospital Medical Center grew tissues from the stomach's corpus/fundus region.
13/01/2017The complexity of neural networks makes them difficult to analyze, but manmade computing systems should be simpler to understand.
11/01/2017A landmark study, led by Monash University's Biomedicine Discovery Institute with the involvement of the Peter MacCallum Cancer Centre, has revealed the reason why men with a family history of prostate cancer who also carry the BRCA2 gene fault have a more aggressive form of prostate cancer.
10/01/2017Basel-based doctors are on the trail of a possible connection between autoimmune diseases and infections: errors can occur when immune cells absorb certain proteins from pathogen cells. These findings were reported in the journal PNAS by researchers from the Department of Biomedicine at the University of Basel and University Hospital Basel, as well as colleagues in the USA.
05/01/2017Bacteria that are susceptible to antibiotics can survive when enough resistant cells around them are expressing an antibiotic-deactivating factor. This new take on how the microbial context can compromise antibiotic therapy was published by a team of microbiologists from the University of Groningen microbiologists, together with colleagues from San Diego, in the journal "PLOS Biology".
03/01/2017Until it burst onto the scene earlier this year, Zika was an obscure, little-known virus. As a result, scientists know little about how it works. Over the past year, they have learned that it can cause a range of dangerous health problems, including birth defects such as microcephaly and neurological problems such as Guillain-Barré syndrome.
03/01/2017A treatment billed as a potential breakthrough in the fight against disease, including cancer, could back-fire and make the disease fitter and more damaging, new research has found. Ground-breaking research has found that introducing 'friendlier' less-potent strains into a population of disease-causing microbes can lead to increased disease severity.
