New discovery provides insight into complex Rad50 molecular motor function

Over the last years, two teams of researchers at The Scripps Research Institute have steadily built a model of how a powerful DNA repair complex works. Now, their latest discovery provides revolutionary insights into the way the molecular motor inside the complex functions - findings they say may have implications for treatment of disorders ranging from cancer to cystic fibrosis.

Antioxidants in walnuts can reduce risk of heart disease

A new scientific study positions walnuts in the No. 1 slot among a family of foods that lay claim to being among Mother Nature's most nearly perfect packaged foods: Tree and ground nuts.

Almac, BioFocus partner to provide FLT assays

BioFocus and Almac have initiated a collaboration which will provide BioFocus customers with compound screening and profiling services using Almac's FLEXYTETM fluorescence lifetime assays.

New discovery may improve cochlear implants for deafness

University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain.

Findings conflict with traditional view of how epileptic seizures begin

The first study to examine the activity of hundreds of individual human brain cells during seizures has found that seizures begin with extremely diverse neuronal activity, contrary to the classic view that they are characterized by massively synchronized activity.

Researchers discover LRRK2 gene mutation may cause Parkinson's disease

Researchers at Mount Sinai School of Medicine have discovered a way that mutations in a gene called LRRK2 may cause the most common inherited form of Parkinson's disease.

Major breakthrough in brain signal processing

A team of Neuroscientists from NeuroCure Cluster of Excellence at Charité - Universitätsmedizin Berlin and Baylor College of Medicine in Houston, Texas, have made a major breakthrough in understanding how signals are processed in the human brain.

NeoProteomics secures exclusive option agreement with Case Western Reserve University

NeoProteomics Inc., a biomarker development and software company, has secured an exclusive option agreement with Case Western Reserve University. The deal has potential to enhance various forms of treatment of cancer, diabetes, and inflammatory diseases.

Scientists discover how neurons communicate with each other

There are billions of neurons in the brain and at any given time tens of thousands of these neurons might be trying to send signals to one another. Much like a person trying to be heard by his friend across a crowded room, neurons must figure out the best way to get their message heard above the din.

Researchers identify genetic conspirators underlying acute myeloid leukaemia

Researchers have described how the most common gene mutation found in acute myeloid leukaemia starts the process of cancer development and how it can cooperate with a well-defined group of other mutations to cause full-blown leukaemia.

Plasmid containing Sindbis replicase genes can destruct lung cancer

Alpha viruses, such as Sindbis virus, carry their genetic information on a single strand of RNA. On infection they use a protein, replicase, to produce double stranded RNA which is used as genetic material to make more viruses. However the body recognizes dsRNA as foreign, and infected cells initiate an immune response.

Researchers identify new mechanism underlying MS

Multiple sclerosis is a disabling autoimmune disease in which nerve fibers are attacked by the patient's own immune system. Researchers at Ludwig-Maximilians-Universitaet in Munich have identified a new mechanism that contributes to nerve fiber damage - and shown that this damage can be reversed.

Scientists discover how odors are detected and processed by brain

Researchers seeking to unravel the most ancient yet least understood of the five senses - smell - have discovered a previously unknown step in how odors are detected and processed by the brain.

Zileuton can help reduce amyloid plaque formation and Alzheimer's development

A drug used to treat asthma has been shown to help reduce the formation of amyloid beta, a peptide in the brain that is implicated in the development of Alzheimer's disease, according to researchers at Temple University's School of Medicine.

Researchers identify enzyme biomarker that can diagnose early colon cancer

A research team at the University of Colorado Cancer Center has identified an enzyme that could be used to diagnose colon cancer earlier. It is possible that this enzyme also could be a key to stopping the cancer.

HIV uses base excision repair pathway to insert DNA into host-cell genome

The human immunodeficiency virus (HIV), the cause of AIDS, makes use of the base excision repair pathway when inserting its DNA into the host-cell genome, according to a new study led by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. Crippling the repair pathway prevents the virus from completing this critical step in the retrovirus's life cycle.

Study identifies unique adult animal stem cells that can turn into neurons

A group of scientists at Marshall University is conducting research that may someday lead to new treatments for repair of the central nervous system.

Study develops new approaches for sorting out complexities of cancer cells

New drugs that specifically target the mutated genes responsible for cancer growth have shown great success in extending the lives of patients, with far fewer side effects than conventional anti-cancer therapies. Unfortunately, many patients become resistant to these drugs due to secondary mutations.

First evidence of H5N1 transmission between domestic farms and wild birds

Wild migratory birds may indeed play a role in the spread of bird flu, also known as highly pathogenic avian influenza H5N1.

Study explains how genetic mutations lead to development of Parkinson's disease

Researchers at Mount Sinai School of Medicine have discovered a way that mutations in a gene called LRRK2 may cause the most common inherited form of Parkinson's disease. The study, published online this month in the journal Public Library of Science, shows that upon specific modification called phosphorylation, LRRK2 protein binds to a family of proteins called 14-3-3, which has a regulatory function inside cells.
