Chemists create 'Superbowl' molecule; May lead to better health

...Australia have created a "superbowl" molecule that shows promise for precision drug delivery, according to ...ing lives, the researchers say. The molecule also shows promise for a wide range of other applications, including the removal of environmental toxins and ai...

Molecular biology fills gaps in knowledge of bat evolution

...er, this latest research is significant because it shows that molecular information can contribute to resolving and illuminating long-standing problems in evolutionary biology. The current findings lay the groundwork for further research that, Springer hopes, will expand the coverage of classifications of...

...t Harvard Medical School.She adds, "This data also shows the kind of payback that can come fromstudies of lower animals like newts and sponges. Combining theknowledge of Hox11's role in those animals with what we'd found aboutislet cell regeneration in mice helped us find this previously unknownexample of ...

Genes In The Interferon System Important In Systemic Lupus Erythematosus

...ty.The study, comprising nearly 2,000 individuals, shows that two genes inthe interferon system are very strongly associated with the diseaseSLE. One of the genes codes for a so-called thyrosinkinase enzyme,whose function is to convey signals from interferon outside the cellsto the cell nucleus."We found t...

Study Demonstrates Gene Expression Microarrays are Comparable and Reproducible

...stitute, part of the NationalInstitutes of Health, shows for the first time that microarray datagenerated in different laboratories can produce highly comparableresults. For this comparison study, appearing in the Jan. 15, 2005,Clinical Cancer Research*, four separate laboratories analyzed geneexpression (...

Ancient olfaction protein is shared by many bugs, offering new pest control target

...ssential for the sense of smell in fruit flies now shows that this gene's function appears to be evolutionarily conserved across very different insect species. Research by Leslie Vosshall's laboratory had previously shown that of 62 odorant-receptor proteins expressed by fruit flies, 61 are exclusively ex...

Live Recombinant Adenovirus Vaccine Technique Explored

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...ix, a California technology company. The analysis shows a striking and surprising exception in the way some critical genes are activated by the protein packaging. These proteins act like spools for the long strings of DNA that contain our genes and form chromosomes. The researchers studied chemical tags t...
