First thought reading brain chip implanted in USApril 1st, 2005 A paralysed man in the US has become the first person to benefit from a brain chip that reads his mind. Matthew Nagle, 25, was left paralysed from the neck down and confined to a wheelchair after a knife attack in 2001.
Ultimate Human Computer Interface - Mind Control: Research on Mind Control & Thought ReadingJune 8th, 2007 Imagine the best way to give dictation (without spelling mistakes) or to program without typing and that pesky carpal tunnel syndrome - by pure mind control alone. Scientists at Brown University and Cyberkinetics Neurotechnology Systems (and others) have made this possible; as published last week in Nature.
Gene keeps neural cells on correct developmental pathMay 23rd, 2005 Embryonic stem cells with identical genomes grow into distinctive tissues, such as heart, bone, and brain. At one time, scientists believed the differences among cell types arose from various sets of genes switched on inside developing cells.
Way to go Massachusetts! Another state becomes wiser to the needs of stem cell researchApril 3rd, 2005 A bill that would allow embryonic stem cell research in Massachusetts cleared its second big legislative hurdle on Thursday with enough support to withstand a near-certain veto by the state's governor. Following impassioned argument on both sides, the state House of Representatives voted 117-37 in favor of legislation that endorses stem cell research, including stem cells obtained from cloned human embryos.
Umbilical Stem Cell BreakthroughAugust 24th, 2005 A new type of cell discovered in umbilical-cord blood promises to overcome the ethical and legal dilemmas surrounding the use of embryonic stem cells. International researchers who discovered the cells - called cord-blood-derived-embryonic-like stem cells, or CBEs - have found a way to mass produce them.
Key to Holy Grail of Stem Cell Research Found by Korean ScientistsAugust 24th, 2005 A Korean husband-and-wife scientist team has made headway in adult stem cell research by discovering a gene in charge of differentiating the parent cells in human bodies. “Up until now, researchers have dug up many factors involved in the differentiation of adult stem cells.
Research finds Statin simvastatin appears to prevent or reverse vascular injury in diabetic ratsApril 3rd, 2005 Since most patients with diabetes die from some vascular complication, Medical College of Georgia researchers set out to determine the effects of simvastatin on endothelial cell dysfunction, an early pivotal event in atherogenesis and a major cause of the microvascular complications in diabetics. The researchers found that in addition to lowering cholesterol levels, simvastatin also appeared to prevent or reverse vascular injury by vasoprotective means.
Congratulations: You Have Nearly As Many Genes As Trick ParasiteJanuary 13th, 2007 A simple one-celled parasite called Trichomonas Vaginalis, also known as "trick", which causes an itchy and smelly genital infection especially dangerous to women, has nearly as many genes as a human being, researchers reported on Thursday. They mapped the genome of Trichomonas vaginalis, which causes the most common non-viral sexually transmitted infection, and hope they have found a few chinks in its armor.
Single Insulin Regulator Gene Linked to Obesity and DiabatesJuly 18th, 2005 A gene that may regulate the body's response to insulin has been linked to both obesity and type-2 diabetes, researchers in Britain and France reported on Monday. Scientists found 11 different variations of the gene, called single nucleotide polymorphisms or SNPs.
Interfering RNA ( siRNA ) helps monkeys recover from SARSSeptember 8th, 2005 Researchers at Sun Yat-sen University in Guangdong, China, and Intradigm in Maryland, have reported the first successful use of Interfering RNA (siRNA) against the viral respiratory disease SARS, in primates (Nature Medicine, DOI: 10.1038/nm1280). Two siRNA sequences that matched bits of the SARS virus genome largely protected macaques against SARS when given as nasal sprays shortly before, or four hours after, infection.
Rice University have developed metal "nanoshells" to detect and destroy cancer cellsApril 14th, 2005 Researchers at Rice University in Texas have developed a new approach to fighting cancer, based on nanoscale particles that can both detect and destroy cancerous cells. The report appears in the April 13 issue of the American Chemical Society's journal Nano Letters.
New test of biomarkers for diagnosing and treatment of organ transplant rejectionsApril 18th, 2005 Researchers at St. Paul’s Hospital and Vancouver General Hospital are developing a revolutionary new test to diagnose and facilitate treatment of organ rejection in transplant patients.
Japanese scientists increased insulin production in mice by overexpression of transcription factorsApril 18th, 2005 A group of Japanese scientists has used gene therapy to deliver three insulin transcription factors, MafA, PDX-1, and NeuroD, to the livers of diabetic mice. As a result, the mice experienced an increase in insulin gene expression and insulin production, raising the possibility that this could eventually be used to treat diabetes.
Gene expression inhibitor drug made mice (STZ induced) diabetes resistantMarch 21st, 2005 Researchers from North Shore-Long Island Jewish Health System in Manhasset, N.Y. have identified a gene which expresses as a protein called macrophage migration inhibitory factor, or MIF.
Biocavity laser is now used to study stem cell functionsApril 1st, 2005 The biocavity laser can show scientists the inner workings of a single cell. Paul Gourley and his colleagues at Sandia proved the laser could do that by studying cancer cells.
