New Discovery in DNA Repair!

In recent research into the process of DNA repair on a molecular level, biologist at Duke Cancer Institute have discovered a complex issue. The tightly wound DNA in the cell nucleus (called a nucleosome) is the downfall to natural DNA repair; the DNA is simply too tight. If an issue in sequencing or damage occurs deep in the complexity of the DNA coils, there is little chance of the cell being able to use proteins and nucleic acids to self-repair the DNA.
What the researchers at Duke Cancer Institute discovered is the need to use proteins to disrupt the nucleosome. When the nucleosome can be disrupted – loosened – then DNA repair can be properly preformed.
This is significant in cancer therapy because it will allow for the DNA of tumor cells to be manipulated to be more sensitive to radiation treatment. Future DNA modifications are also possible with the knowledge of the DNA repair process. (Read more…)

A recent study at the University of Helsinki in Finland was performed to show how much of an impact that eating disorders have on pregnancy. The study lasted fifteen years long and showed that women with eating disorders are two times less likely to conceive and if they do get pregnant then they are three times more likely to have a miscarriage. These are shocking statistics. Based on previous research, both obesity and being underweight have huge lifelong effects on pregnancy. (Read more…)

Bittersweets of Taste

In a recent study by researchers in Buffalo, New York, mice which are obese have a significant lose of the sense of sweet taste. Even the taste buds left which can detect sweet are weak at receiving the signal. This is significant in weight gain because the taste of sweet has been found to be the most commonly desired; a lack of the ability to taste it has the tendency to lead to an excessive intake of sweet foods, thus leading to obesity.

Many people don’t know that crows are actually highly intelligent. Thus, Neurologists turn to science to find out the cause of this. The scientists did a variety of memory tests on the crows and the results showed the crows having a high level of concentration and mental flexibility, which can even be a struggle for some humans. These crows apply this knowledge when they need to remember feeding sites and learn behaviors from their fellow group members. (Read more…)

Thousands of seeds and nuts were discovered in several fossil burrows ancient squirrels used to store food. Scientists used the vitro tissue method to revive and grow 36 of the ancient plants. After artificially pollinating the seeds, it took 8-9 weeks for them to flower, and they now claim these plants are the most ancient organisms ever revived.(Read more…)

Superhuman Ballerinas

Ballet dancers are known for being able to whip out multiple pirouettes, land gracefully, and then easily sashay into a grande jeté, a high leap with one leg extended in front and one in back. Scientists want to know how ballerinas can withstand the fast rotations of a pirouette without becoming dizzy. Dancers use a technique called “spotting”, which involves concentrating on a certain point in space and then whipping your head around to meet it with each turn. However, scientists have found that “spotting”, though effective, is not the main factor keeping dancers on their toes. (Read more…)

Dog Days of Fish

Due to the ocean waters becoming warmer, many species of fish near the Great Barrier Reef have become lethargic and less able to swim. A prominent species that lives on the reef is the Coral Trout. These fish are also one of highest sought-after fish species in the South-East Pacific for fisheries. Scientists and fishermen alike are worried about the lasting effects of the fishes’ lethargy. Aside from reducing their ability to swim, the warm waters have caused the trout to stay near the bottom of the reef, instead of near the top looking for food or mates. (Read more…)
