Hauls of Shame - Breaking News
In boxing alone, there were dozens and dozens more that merit mentioning but space and time constraints precluded them from being here unless people want a list longer than your arm, same for historical, music, and entertainment. The Honus Wagner Ornate-Style Signature Signed On A 1949 Leaf Baseball Card- Jimmy Spence and Steve Grad authenticated this Honus Wagner signature (above left) for Hunt Auctions in 2004 despite the fact the ornate Wagner signature could not have been signed earlier than 1949 when the card was issued by Leaf
ANTI-AGING FIREWALLS - THE SCIENCE AND TECHNOLOGY OF LONGEVITY
The blog post New views of Alzheimer's disease and new approaches to treating it describes how senesence of microglia may be a root cause of Alzheimer's dementia. Prevention of this shortening by telomerase activation could prevent premature senescence of these cells, and could possibly prevent some of the pathological consequences of SLE
We should accept only a solution which honors the full spectrum of possible experiences in the cosmos, from the most empirically public to the most esoterically private. Really?! Empty space cannot contain energy? He simply makes assertions , some of which are inherently meaningless and some of which are unproven, or worse, have proof against
Sexual Reproduction
The tranquilizer, thalidomide, taken by many pregnant European women between 1954 and 1962, turned out to be a potent teratogen and was responsible for the birth of several thousand deformed babies. Virus infection of the mother, e.g., by rubella ("German measles") virus or exposure to certain chemicals may cause malformations in the developing embryo
Those haplogroups include what is known as the Polynesian motif and are found in Indonesian populations and also in Madagascar, according to the paper, but the time to the most common recent ancestor for that motif was calculated at 9,300 years plus or minus 2000 years. Was the war somehow part of the reason? Was the journey more dangerous because of the war? Surely it was, because the Indians had allied themselves with the British
MECHANISMS OF AGING
Until molecular repair technologies are available, good health practices, supplements and organ transplantation are our best hope of bridging the time between now and the Age of Negligible Senescence. Rad52 protein recognizes the DSB and adheres to the free ends of the break (comparable to Ku in NHEJ) while Rad51 searches the undamaged sister chromatid for a homologous repair template
ENCODE: the rough guide to the human genome - Not Exactly Rocket Science : Not Exactly Rocket Science
In particular, priors in Bayesian statistics offers a very fair and natural way to apportion the burden of proof in an entirely impartial way, unlike tendentious choice of which is the null and which is the alternative hypothesis. Just the breathless, uncritical touting of a dubious figure that even a major contributor to the collaboration is loath fully endorse when he expounds at length
Mitosis and Meiosis Pipe Cleaner Simulation: Crossing Over and Independent Assortment -
The teacher should not insist that the students follow him or her exactly in regards to how the homologous pairs are lined up (although, red and pink should still be next to one another; the same with blue and light blue). Feedback to Students Students will initially work in pairs and will get feedback from both their peers and their teacher as they design a method of cell division that makes two identical copies of a cell
DNA and RNA Tumor Viruses
For example, as noted above, if we have a receptor that sends a signal when it binds a growth factor by switching on its tyrosine kinase activity and that receptor becomes mutated so that its tyrosine kinase activity is permanently activated, the cell will get the aberrant growth signal even in the heterozygote. Nevertheless, in many instances the epidemiological data are very strong and, in the case of human cervical cancer, the efficacy of the anti-HPV vaccine makes the contention that HPV does cause cervical cancer very compelling
From DNA to RNA - Molecular Biology of the Cell - NCBI Bookshelf
The long C-terminal tail of the RNA polymerase coordinates these processes by transferring capping and splicing components directly to the RNA as the RNA emerges from the enzyme. Picking out the precise borders of an intron is very difficult for scientists to do (even with the aid of computers) when confronted by a complete genome sequence of a eucaryote
homeobox: Homeoboxes are relatively short (approximately 180 base pair) sequences of DNA, characteristic of some homeotic genes (which play a central role in controlling body development). (Less formally, according to Medawar's definition, a virus is "a piece of bad news wrapped in a protein.") vitamin A: A member of a chemically heterogeneous class of organic compounds that are essential, in small quantities, for life
A failed replication draws a scathing personal attack from a psychology professor - Not Exactly Rocket Science : Not Exactly Rocket Science
One way people get round this is to report separate by-participants and by-items analyses, with the logic being that if you get the same effects for both, it suggests the effect is not specific to the stimuli you used. The wall might keep standing but how many bricks would need to be removed before you would hesitate to stand next to it? Direct replication of specific experiments is vital yet grossly undervalued
According to the conservative replication model, the entire original DNA double helix serves as a template for a new double helix, such that each round of cell division produces one daughter cell with a completely new DNA double helix and another daughter cell with a completely intact old (or original) DNA double helix. "If several different density species of DNA are present," they predicted, "each will form a band at the position where the density of the CsCl solution is equal to the buoyant density of that species
Animal Cell Mitosis
Some mitotic spindle fibers elongate from the centrosomes and attach to kinetochores, protein bundles at the centromere region on the chromosomes where sister chromatids are joined
