Australian scientists have charted the path of insulin action in cells in precise detail like never before. This provides a comprehensive blueprint for understanding what goes wrong in diabetes. http://medicalxpress.com/news/2013-05-insight-dazzling-impact-insulin-cells.html Medical research Tue, 21 May 2013 11:25:38 EST news288354330 (Medical Xpress)—By studying what happens in the normal brain when neurons fire, Australian scientists have been able to identify a finely and dynamically regulated process. They also describe how dysfunction of this process is associated with schizophrenia. http://medicalxpress.com/news/2013-05-faulty-neural-schizophrenia-revealed.html Psychology & Psychiatry Thu, 02 May 2013 08:34:39 EST news286702472 (Medical Xpress)—For an immune response to get underway, an invading microbe must first be halted in the spleen, and then digested by immune cells known as 'dendritic cells', which guard specific portals. Australian scientists have now shown how these gatekeepers position themselves to undertake their task. http://medicalxpress.com/news/2013-03-immune-positions-gatekeepers.html Immunology Tue, 19 Mar 2013 08:29:23 EST news282900532 (Medical Xpress)—Early diagnosis and intervention for ADHD, autism and schizophrenia could be made possible after Australian scientists discovered the molecular networks in the brain showing psychiatric and developmental disorders. http://medicalxpress.com/news/2013-02-reveals-molecular-networks-mental-health.html Psychology & Psychiatry Wed, 27 Feb 2013 10:40:01 EST news281183424 Australian scientists are getting closer to decoding the way molecules interact to enable regular heart function. http://medicalxpress.com/news/2012-11-calcium-role-healthy-heart.html Cardiology Wed, 21 Nov 2012 08:44:26 EST news272709848 Australian scientists have confirmed a 'weak link' in the immune system – identifying the exact conditions under which an infection can trigger an autoantibody response, a process not clearly understood until now. http://medicalxpress.com/news/2012-11-infection-trigger-autoimmune-disease.html Immunology Fri, 09 Nov 2012 10:01:04 EST news271677651 Australian scientists said Thursday they had successfully implanted a "world first" bionic eye prototype, describing it as a major breakthrough for the visually impaired. http://medicalxpress.com/news/2012-08-australians-implant-world-bionic-eye.html Ophthalmology Thu, 30 Aug 2012 04:07:23 EST news265518432 Australian scientists have discovered a new virus in bats that could help shed light on how Hendra and Nipah viruses cause disease and death in animals and humans. The new virus - named 'Cedar' after the Queensland location where it was discovered - is a close relative of the deadly Hendra and Nipah viruses. http://medicalxpress.com/news/2012-08-virus-key-hendra.html Diseases, Conditions, Syndromes Thu, 02 Aug 2012 17:43:58 EST news263148225 (Medical Xpress) -- Expression levels of a DNA repair gene called MGMT have been widely studied across many cancers as a biomarker of response to temozolomide, a chemotherapeutic agent. Now Australian scientists have published findings suggesting MGMT may also play a significant role in tumour progression. http://medicalxpress.com/news/2012-07-pituitary-tumours-biology-cancers.html Cancer Mon, 30 Jul 2012 08:15:26 EST news262854791 Australian scientists have identified a gene that regulates muscle size, a finding that could help unlock therapies for Type 2 diabetes and diseases such as muscular dystrophy, where muscles are weakened and damaged. http://medicalxpress.com/news/2012-05-muscular-approach-diabetes-diseases.html Genetics Wed, 30 May 2012 09:20:02 EST news257586817 Australian scientists have discovered that a biological phenomenon known as ‘somatic reversion’, when an abnormal gene spontaneously becomes normal again, explains why some patients with a rare genetic disorder live much longer than they should. http://medicalxpress.com/news/2012-04-potential-gene-therapy-patients-rare.html Medical research Thu, 12 Apr 2012 11:06:55 EST news253447606 Australian scientists have discovered for the first time how nature and nurture combine to increase the risk for women of giving birth to a baby with congenital defects, according to a study published today. http://medicalxpress.com/news/2012-04-scientists-congenital-birthdefects.html Medical research Fri, 06 Apr 2012 09:09:39 EST news252922157 The pulse quickens, the heart pounds and adrenalin courses through the veins, but in stressful situations is our reaction controlled by our genes, and does it differ between the sexes? Australian scientists, writing in BioEssays, believe the SRY gene, which directs male development, may promote aggression and other traditionally male behavioural traits resulting in the fight-or-flight reaction to stress. http://medicalxpress.com/news/2012-03-men-aggressively-women-stress-gene.html Genetics Wed, 07 Mar 2012 19:00:01 EST news250359768 New research by Australian scientists reveals that males who are exposed to high levels of testosterone before birth are twice as likely to experience delays in language development compared to females. The research, published in Journal of Child Psychology and Psychiatry, focused on umbilical cord blood to explore the presence of testosterone when the language-related regions of a fetus' brain are undergoing a critical period of growth. http://medicalxpress.com/news/2012-01-prenatal-testosterone-linked-language-male.html Psychology & Psychiatry Thu, 26 Jan 2012 04:17:06 EST news246773797 Australian scientists have developed a new technique using stem cells, in the hope to replace damaged cells in Parkinson's disease.
