The secret lives of whales

... Hawaii and Roger Payne of the Ocean Alliance will share their latest discoveries emerging from these high tech ventures, using DNA sequences, deep-sea video and sound-clips. Reading the Past from DNA “Genetics is opening the door to a huge storehouse of historical information about whales,?says Steve Pa...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

...ces. Often, transcripts from one strand of DNA can share parts of their sequence with overlapping transcripts from the same strand or even from the opposite strand (antisense). Transcripts missing a run of adenosine nucleotides (non-polyA) at the tail-end were twice as common as the more well-studied RNAs ...

New RNA polymerase discovered in plants

... his collaborators discovered that Pol IV does not share in the duties of Pol I, II or III. But when the Pol IV subunits are knocked out, the most tightly packed DNA in the nucleus becomes less condensed, small RNAs called siRNAs corresponding to highly repeated 5S rRNA genes and retrotransposons (jumping ...

RNA project to create language for scientists worldwide

... previously determined that humans and chimpanzees share 99 percent of the same protein genes, it has now been discovered in the past two years that so do mice. "The hardware (proteins) for mice and humans is practically the same–but clearly mice and humans are different. Since the hardware is the same, t...

Scientists solve structure of key protein in innate immune response

...ith LPS for CD14 binding. Therefore, they probably share the same binding pocket with LPS." Ligands other than LPS can be accommodated in the pocket due to its large size, the flexibility of its rim, and the multiple grooves available for ligand binding. The researchers also discovered that mutations that...

Asthma gene clusters identified

Children who suffer from acute asthma attacks share a genetic profile that appears to be unique to these children, according to a new study by researchers at Cincinnati Children's Hospital Medical Center. The discovery opens the door to the possibility of designing treatments specifically tailored to ...

Genetically modified rice in China benefits farmers' health, study finds

Chemists identify immune system mechanism for methamphetamine binges

Tolerance refers to the capacity to have a decreased response to a drug after prolonged use. Increase...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...appens to the plants after they've soaked up their share of selenium? The researchers say that the plants can be harvested, dried and carefully added to animal feed or used as a soil amendment in areas where selenium is in short supply. "There are many areas where selenium is deficient, so farmers actuall...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...n says. Species with similar amino acids sequences share an overlapping set of shapes, which helps explain why species with shared sequences have the ability to infect each other. Surewicz says the next step in their research will be to examine fibril shape differences at much higher resolution. Their exp...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

...ex drive. Brain systems were activated that humans share with other mammals. So the researchers think "early-stage romantic love is possibly a developed form of a mammalian drive to pursue preferred mates, and that it has an important influence on social behaviors that have reproductive and genetic consequ...

Medical whistleblowers speak out

Lenzer's account of the roundtable, in which she outlines the lessons we can learn from these whistleblowers, is published in th...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...ebohm, Ph.D., shows that these replaceable neurons share something in common with the neurons that die in people with diseases such as Alzheimer's and Parkinson's: both have unusually low levels of a protein called UCHL1. "It would be ironic if the shortfall in a same gene brokered the path to brain disea...

Master gene controls healing of skin in fruit flies and mammals

...innis. "So it is remarkable that flies and mammals share an ancient conserved pathway to construct and repair the body envelope that protects them from sharp edges and microbes, even though that body envelope is constructed of mostly different molecules." In their paper, the UCSD researchers state that st...

Molecular fossils uncover link between viruses and the immune system

One plausible explanation may be that viral building blocks served as precursors for the evolutionary more recent immune system of animals. These results are an outcome of recent advances in structural biology, a new discipline i...
