Termites feed through good vibrations

... on large blocks had this characteristic frequency plus other signals indicating the presence of other termites in that "large block", so they chose to feed on the large block without termites. Thus the termites showed that they have the "cocktail party effect". This social information had another import...

New Technique for Tracking Gene Regulators

...ces, which all have the same startsequence of CATG plus 16 additional unknown bases. The scientists then“glue?together the tags into chains and sequence them.While small in length, the tags are large enough to allow computersearches to locate their specific positions on the complete genome in amanner that...

Key mechanism in genetic inheritance during cell division identified

...ogy, who were the lead investigators on this work, plus Agustin Avila-Sakar and Hong-Wei Wang, with Berkeley Lab, and Hanspeter Niederstrasser and Jonathan Wong with UC Berkeley.

Yeast Network Prevents Damage By Oxygen Radicals

...ene, which results in increased production of ROS, plus a mutation in one or more genes involved in DNA repair or cell cycle control. Cell survival and accumulation of DNA mutations and gross chromosomal rearrangements in each strain were then analysed to identify genes that cooperate to prevent the delet...

Maine Researchers Find Exceptions to Old Rules of Genetic Inheritance

... that males carrying two copies of the t haplotype plus the transgenic region were fertile and showed no transmission ratio distortion. Therefore, the scientists realized, two genes must be involved-one controlling sterility and a yet-to-be discovered gene regulating transmission ratio distortion. Dr. Pl...

Oldest cranial, dental and postcranial fossils of early modern European humans confirmed

...Europe which retains many portions of the skeleton plus archaeological objects from the Aurignacian period. Only two modern human specimens from a site in Romania, dated to ~35,000 years ago, are older. At Mladec there are multiple individuals - at least 5 or 6 represented. The dating shows that the Mlade...

"Other notable observations were that increased levels of surfactant apoprotein B protein normally caused by nicotine were reduced by vitamin C. In addition, elas...

Hepatitis C responds best to combo of ribavirin and interferon, study concludes

Among those who had relapsed after previous treatment 87 percent of interferon-only patients did not respond, compared to 51 percent who were on combination therapy. Of the patients who had not responded at all to previous therapy, 95 pe...

Researchers predict infinite genomes

...ery strain (thus constituting the GBS core genome) plus 439 genes absent in one or more strains. Moreover, mathematical modeling showed that unique genes will continue to emerge, even after thousands of genomes are sequenced. The GBS pan-genome is expected to grow by an average of 33 new genes every time ...
