21 GIFs That Explain Mathematical August 26, 2014 | by Lisa Winter As we usher in the start of a new school year, it’s time to hit the ground running in your classes! Math can be pretty tough, but since it is the language in which scientists interpret the Universe, there’s really no getting around learning it. Check out these gifs that will help you visualize some tricky aspects of math, so you can dominate your exams this year. Concepts |

Make like a squid and transform: Squid can recode their genetic make-up on-the-fly to adjust to their surroundings, study finds
The principle of adaptation -- the gradual modification of a species' structures and features -- is one of the pillars of evolution. While there exists ample evidence to support the slow, ongoing process that alters the genetic makeup of a species, scientists could only suspect that there were also organisms capable of transforming themselves ad hoc to adjust to changing conditions.
"We have demonstrated that RNA editing is a major player in genetic information processing rather than an exception to the rule," said Dr. Eisenberg. "By showing that the squid's RNA-editing dramatically reshaped its entire proteome -- the entire set of proteins expressed by a genome, cell, tissue, or organism at a certain time -- we proved that an organism's self-editing of mRNA is a critical evolutionary and adaptive force." This demonstration, he said, may have implications for human diseases as well.

Swimming reptiles make their mark in the Early Triassic , PLEASE NOT ON MY PARQUET !
Vertebrate tracks provide valuable information about animal behavior and environments. Swim tracks are a unique type of vertebrate track because they are produced underwater by buoyant trackmakers, and specific factors are required for their production and subsequent preservation. Early Triassic deposits contain the highest number of fossil swim track occurrences worldwide compared to other epochs, and this number becomes even greater when epoch duration and rock outcrop area are taken into account.

A simple blood test that can detect different types of cancer is being developed by researchers in the UK
The tools we currently have to detect cancer, such as colonoscopies and biopsies, are expensive, invasive and painful. So a team of researchers led by Diana Anderson, professor of biomedical science at the University of Bradford’s School of Life Sciences in Yorkshire, is developing a universal blood test that can detect a range of cancers.

Stessa fitness anche se la diversità genetica aumenta.
Le popolazioni che inizialmente hanno una ridotta capacità di successo riproduttivo tendono ad accumulare mutazioni benefiche più rapidamente di quelle che partivano più avvantaggiate, arrivando alla fine allo stesso livello di fitness. Il fenomeno è dovuto alle interferenze che possono verificarsi fra geni diversi, per cui una mutazione benefica può silenziare gli effetti di un'altra, precedente o successiva, a carico di un diverso gene

Mesmerizing Gif Shows Cell DivisionMetaphase is the point in the cell cycle after the chromosomes have condensed and lined up in the middle, just before the cell is divided into two daughter cells. The chromosomes are held into place with kinetochore microtubules to create what is known as the metaphase plate, spanning the equator of the cell.

Il virus del morbillo batte il tumore
Il virus del morbillo, inoculato in forma ingegnerizzata in grandi quantità, ha portato alla remissione completa dei tumori che colpivano una paziente statunitense: è la prima volta che si documenta il successo dell'attività antitumorale di un virus nell'essere umano. Il risultato, per quanto incoraggiante, dovrà comunque essere verificato con studi clinici su un ampio numero di pazienti

OGM : Le responsabilità di chi si oppone al Golden Rice
