Action of nerve cells

...icals called neurotransmitters. In a new study, biologists from Utah showed how a single protein plays an importnat role in preparing the nerve cells to send these chemical signals. The experimented animals were paralyzed- unable to move, eat or// eliminate waste-when the Scientists crippled the protein U...

The phenomenon of sexual attraction

...s and humans at a sub-conscious level. Research by biologists Astrid Juette and Professor Karl Grammer from the University of Vienna has found that men's perception of a woman's attractiveness is altered by the chemical signals she sends out. They exposed 76 men to synthetic vaginal pheromones without their kno...

Disease chromosomes identified

...s or biological responses. With the new knowledge, biologists believe it is possible to pre-programme every human trait from hair colour to sexuality. Each chromosome carries thousands of genes that act as instructions for the manufacture of proteins controlling everything that occurs in the body. HGP indicat...

Crusade Against Cancer: Collaborations On The Anvil

...It is hoped the new center will allow chemists and biologists to work closely with doctors at Christie to take advances from the lab straight on to the hospital ward. Professor Nic Jones, director of the Paterson Institute, who will become director of the MCRC, said: "In the short term we will become a centre o...

Link between Old Cells and Ageing probed

...age factor and ageing cells? Now, Brown university biologists have found new proof that might establish this connection between old cells and old bodies. // During a study of baboons, it was discovered that as the baboons aged, their skin showed an increased presence of old cells. It is well known that, as we...

Genomatix Licensed By Bayer Healthcare

...ch is now licensed by Bayer HealthCare. It enables biologists and bio-informaticians to analyze chip raw data//. It employs the latest genomic annotation. It combines both literature and pathway mining in a single coherent system. ‘After several successful pilot studies we are now very pleased that Bayer H...

Treatment of Bacterial Infection Paves the Way to Treat CF Infection

...p1, into the Protein Data Bank, a resource used by biologists worldwide to find information about the proteins they are studying. While exploring the Protein Data Bank, Mougous, who was studying PA in the laboratory of department chair John Mekalanos, recognized that the amino acid sequence of Hcp1 in PA closel...

Renewable Oocytes of Mice created hope in Human Fertility Treatment

...my and Cell Biology, has sparked controversy among biologists and challenged the theory, held for more than 50 years, that female mammals are born with a finite number of oocytes (eggs). Two years ago, international researchers speculated that mice could continue to produce eggs throughout puberty and adultho...

Bio Farma To Import Bird Flu Vaccine

...as met with stiff resistance from critics and some biologists who fear that the move could lead to the development of more virulent strains of the bird flu virus. Bio Farma in association with Biken Kanonji Institute of Japan also plans to produce bird flu vaccine for humans by the end of the year. ...

Long-life genes - A new way to combat cancer…

...n C. elegans -- a favorite model for developmental biologists and geneticists due to its simple structure and because the entire three-week life is easily scrutinized under the microscope. She found that disabling a single gene, called daf-2, doubled the life of the worm. The daf-2 gene is now known to be pa...

Discerning Sour Taste

A team headed by biologists from the University of California, San Diego has found that the cells and protein responsible to pick up the ‘sour’ taste,// which is the key sensor in the cerebro-spinal fluid. The study, featured on the cover of the August 24 issue of the journa...

'Mix and match' of proteins may have a significant role in immunity

Proteins appear to transform more often than biologists once thought. Cutting and rearrangement of the com...DNA, is cut and rearranged. It has been assumed by biologists for a long period that rearrangement occurs only at the RNA level. However, in 2004, scientists foun...

Techniques for analyzing protein interactions aid in detecting the molecular basis of diseases

...l be of immense help to several cell and molecular biologists especially those involved in detecting the molecular basis of human diseases. The journal’s website: www.cshprotocols.org gives a free access to both these methods. Given the importance of characterizing the molecular networks and signaling pathway...

Evolution of Plant Life Cycle

...ir time as sporophytes. Geneticists, developmental biologists and evolutionists have been wondering how the switch happened and have put forth two competing hypotheses." For each hypothesis, scientists have come up with an evolutionary scheme showing how different plant lineages should be related to explain th...

Strong Evidence Suggests Incidence Of Mating Of Ancestors With Neanderthals

...oncurs with the long disputed speculation of other biologists who had previously suggested such a possibility could contribute to present day human genetic blue print. Genetic and fossil studies concur that humans may have emerged from Africa 200,000 years ago and also hint that they migrated to Europe later 4...

A New Rapid 3-D Cell-Growth Technique For Growing Heart Muscle

... from the fact that it includes bioengineers, cell biologists and heart surgeons – a multidisciplinary group that can tackle both the technical and clinical hurdles in the field of engineering heart muscle. Its focus is to evaluate different platforms for engineering cardiovascular structures in the laboratory....

A New Gene to Contribute in Insulin Metabolism

Chemists and biologists from the new interdisciplinary LIMES (Life and Medical Scientists) Center at University of Bonn have found a new gene //which might, if defect, contribute to the development of Type II diabetes. Flies in which this hereditary factor is defective a...
