Virus-resistant Grapevines
Viruses can cost winegrowers
an entire harvest. If they
infest the grapevines, even
pesticides are often no use.
What’s more, these
chemicals are harmful to the
environment. Researchers are

Methane-producing Molecule Can Also Repair DNA
July 3, 2009 — The Archaea are single-celled organisms and a domain unto themselves, quite apart from the so called eukaryotes (bacteria and higher organisms). Many species live under extreme conditions, and carry ... > full story -
Molecular Differences Found Between Embryonic Stem Cells And Reprogrammed Skin Cells
July 3, 2009 — Researchers have found that embryonic stem cells and skin cells reprogrammed into embryonic-like cells have inherent molecular differences, demonstrating for the first time that the two cell types ... > full story -
Re-Write The Textbooks: Key Genetic Phenomenon Shown To Be Different Than Believed
July 2, 2009 — Because females carry two copies of the X chromosome to males’ one X and one Y, they harbor a potentially toxic double dose of the over 1000 genes that reside on the X chromosome. To compensate ... > full story -
Uncovering How Cells Cover Gaps In Wound Healing And Embryonic Development
July 1, 2009 — Researchers have come a step closer to understanding how cells close gaps not only during embryonic development but also during wound healing. Their study uncovers a fundamental misconception in the ... > full story -
How Cells Reconcile Mixed Messages In Decisions About Growth
July 1, 2009 — The cells in our body are constantly receiving mixed messages. An epithelial cell might be exposed to one signal telling it to divide and, simultaneously, another telling it to stop dividing. The ... > full story -
New Insights Into Formation Of The Centromere, A Key Cellular Structure In Powering And Controlling Chromosome Segregation

Natural-born Divers And The Molecular Traces Of Evolution
June 30, 2009 — When the ancestors of present marine mammals returned to the oceans, their physiology had to adapt radically. Scientists have been studying how myoglobin, the molecule responsible for delivering ... > full story -
Birds With A Nose For A Difference: Avoidance Of Inbreeding In Birds Demonstrated
June 30, 2009 — Avoidance of inbreeding is evident among humans, and has been demonstrated in some shorebirds, mice and sand lizards. Researchers now report that it also occurs in a strictly monogamous species of ... > full story -
Inbred Bumblebees Less Successful
June 30, 2009 — Declining bumblebee populations are at greater risk of inbreeding, which can trigger a downward spiral of further decline. Researchers have provided the first proof that inbreeding reduces colony ... > full story -
