New findings could lead to vaccine for severe malaria

...n Sweden and Makerere University in Uganda has now produced some important findings on how the malaria parasite conceals itself in the placenta. Plasmodium falciparium is the name of by far the most virulent of the four malaria parasites that infect man. It is particularly dangerous in that it also infects t...

More than 10 years of research The Genetics and Microbiology Team at the Public University of Navarre, of which Professor Pisabarro belongs, has been working with the genetic material ...

Peering into the shadow world of RNA

...ome from behind the scenes. In particular, RNA produced by the vast stretches of DNA that do not code for any genes ?long considered “junk?DNA ?may in fact be serving vital duty by governing important aspects of gene expression. This type of RNA is called non-coding RNA, meaning that although it may be bi...

Scientists discover way to block growth of prostate cancer cells

Researchers link ocean organisms with increased cloud cover and potential climate change

...e researchers hypothesized that airborne particles produced by oxidation of the chemical isoprene ?which is emitted by the phytoplankton ?may have contributed to a doubling of cloud droplet concentrations seen over a large area of ocean off the eastern coast of South America. Using complex numerical mode...

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

...so have known some of the steps by which lysine is produced in plants, but they didn't really have the full picture. Leustek and Andre Hudson, a postdoc working in Leustek's lab in Rutgers' Biotechnology Center for Agriculture and the Environment, were able to solve the pathway when they discovered the gene e...

Genome archaeology illuminates the genetic engineering debate

...culture, where approximately 9 billion bushels are produced annually at a value of $30 billion. Corn is an important dietary staple in much of the third world and a bio-fuel source; rice is the primary dietary staple for more than half the world's population. Scientists have long known that the number of c...

Eating protein boosts hormone that staves off hunger

...ed a high-protein diet also gained less weight and produced more PYY than animals that ate the usual amount of protein, they found. In addition, the researchers found that genetically modified mice unable to produce PYY ate more and became markedly obese. The genetically modified mice were also resistant to...

Each laser sampling vaporized enamel that formed during several months and thus represented what Paranthropus ate during that period. By taking several samples off the len...

New technique boosts size of proteins that can be analyzed

...ry characterizes a protein by measuring the masses produced from it." The new technique provides a far more efficient way to break down proteins inside the mass spectrometer -- sprayed, heated and then bashed with gas molecules -- to obtain their pieces for the mass analysis. They are sprayed in an electric...

They then used a technique called "functional imaging" to see when the memory formed in the fly’s brain. "Before training, we could see some calcium flowing into the mushroom body neurons when the flies w...

Selecting life: Scientists find new way to search for origin of life

...e a means to address this problem. Microarrays are produced robotically to spot tens of thousands of microscopic droplets of DNA from as many genes onto a slide, enabling scientists to measure which genes are turned on. This rapidly developing technology can be used to identify, for example, the genes involve...

Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

The next phase of their research, he says, is to look for what triggers the anti-parasite response. However, Lane cautions that this reaction against parasites may come at the expense ...

Progress made in HIV vaccine development

However, DNA may be less potent than vector-based gene delivery strategies. Replication-defective rAd5 has the advantage of targeted...

The ability to measure the forces generated by the BEHM as it contracts is crucial, Birla explains. It's made pos...
