Machine can switch off brain by transmitting harmless magnetic pulses

Professor Snyder's creativity machine was developed at the Centre for the Mind, a joint venture between The Australian National University and the University of Sydney. The machine transmits harmless magnetic pulses through the brain, temporarily switching part of it off, with the potential to reveal an inner genius

Scientists have discovered that a non-genetic molecular process can effect cell behaviour

Genetic mutations, sudden, random and usually harmful changes to the structure of a gene, are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

DakoCytomation has acquired exclusive worldwide rights to develop and commercialize pharmacogenomic diagnostic tests in the field of oncology

Human Genome Sciences, Inc. announced today a license agreement with DakoCytomation A/S (Glostrup, Denmark), under which DakoCytomation has acquired exclusive worldwide rights to develop and commercialize pharmacogenomic diagnostic tests in the field of oncology based on the TRAIL Receptor-1 (TRAIL-R1) and TRAIL Receptor-2 (TRAIL-R2) proteins.

Gene-rich human Chromosome 19 sequence completed

The United States Department of Energy (DOE) Joint Genome Institute (JGI) and Stanford University report today the completion of the sequencing of human chromosome 19, the most gene-rich of all the human chromosomes.

Faster new cloning technique - transcript-based cloning

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function – a painstaking process often requiring years of laboratory trial and error.

Embryonic stem cells attached to a gel matrix instead of suspended in solution

Like many other kinds of cells used in biomedical research, human embryonic stem cells are stored and transported in a cryopreserved state, frozen to -320 degrees Fahrenheit, the temperature of their liquid nitrogen storage bath.

Newly diagnosed non-Hodgkin’s lymphoma linked to monkey virus DNA

Examination of tumors in patients with newly diagnosed non-Hodgkin’s lymphoma found that half of them show evidence of a monkey virus DNA that may have originated from contaminated polio vaccines.

Novel uses for bacterial cellulose, artificial blood vessels, bioengineered wound dressing

New and unique products created from bacterial cellulose — from electronic paper to treatment for wounds — will highlight a one-day symposium at the 227th national meeting of the American Chemical Society, the world's largest scientific society.

Biocompatible adhesives for use with vascular tissue that will speed the process of mending tissue

Surgeons battle time and the body's defenses as they stitch together veins and arteries, whether after an injury or in the course of such treatments as transplants or bypasses. Loss of blood before a site is closed and too much clotting soon after challenge medical care.

A peptide called magainin, found in the skin of the African clawed frog, holds the secret to creating bacteria-killing surfaces

A peptide called magainin, first found in the skin of the African clawed frog, holds the secret to creating bacteria-killing surfaces, according to researchers at the University of Pennsylvania. The Penn scientists have taken a joint experimental-computational approach to mimicking magainin.

Emerging technologies in tissue engineering and regenerative medicine analysis

Pathbreaking developments in tissue engineering and regenerative therapies are facilitating the design and growth of new organs in labs using biopolymer scaffolds and matrices. Analysis of potential markets for tissue engineering reveals that basic problems such as vascularity must be solved before such implants can gain acceptance as standard treatment methods.

Method of Bone Analysis May Clarify Human Origins

Bones, it is said, tell tales, but in the case of the bones of hominids or human ancestors the story has become complex and convoluted, as paleoanthropologists try to decipher relationships between a host of similar species with subtly shifting characteristics in a spotty fossil record.

Newly formed FAS Center for Systems Neuroscience

Harvard has long been recognized for its strength in neuroscience: Researchers in the Faculty of Arts and Sciences (FAS) are leaders in studies of behavior, perception, and brain development, while Harvard Medical School (HMS) was the first in the nation to establish a department of neurobiology.

Snake venom launders out all stains

Purveyors of snake oil and its mythical powers may not have had it all wrong, if preliminary findings with the Florida cottonmouth, bloodstains and a washing machine stay on target. An enzyme extracted from the viper's venom appears to help launder out notoriously stubborn blood spots on clothing.

Immunomodulator induces long-term anti-tumor activity

EntreMed, Inc., a clinical-stage biopharmaceutical company developing therapeutic candidates primarily for the treatment of cancer, today reported that three months following administration with ENMD 0996, preclinical animal models showed inhibition of metastases. Data presented demonstrated that ENMD 0996 specifically blocks the activity of basic fibroblast growth factor (FGF-2), a naturally-occurring protein that stimulates angiogenesis, but had no effect on other angiogenesis stimulators.

Earlier detection of cancer with Transgenomic's WAVE(R) system

Transgenomic Inc. has announced that during the American Association of Cancer Research annual meeting currently underway in Orlando, several of its customers from major research institutions worldwide will present results in which the Company's WAVE System has played an important role.

BHF anti-smoking adverts hit nerve with general public

An incredible 94% of smokers surveyed said they recognised at least one element of the 'Give Up Before You Clog Up' campaign, with the 'dripping fat cigarette' TV advert sticking in the memories of 90% of those surveyed. The survey was conducted by leading research agency, Hall and Partners, who say the statistics beat any other advertising campaign they have worked on.

Three of the world’s top women chemists visit UK to inspire young scientists

Three of the world’s top women chemists are visiting the UK this week (29 March - 2 April) to tour institutions and talk about their research with the aim of inspiring young scientists to emulate their achievements. The inaugural Rosalind Franklin International Lectureship Programme has been masterminded by Professor Susan Gibson, Imperial College London, who funded the initiative with her prize money from the Royal Society Rosalind Franklin Award.
