Queen Bee and her special gene

A recent article, “Single gene separates queen from workers“, discusses a study published in Biology Letters carried out by scientists from Michigan State University and Wayne State University. They found a gene, which affects not only leg and wing development in bees but also the evolution of a bee’s ability to carry pollen. This gene, known as […]

Microglia! Here to the Brain Rescue?

Microglia

Recently, Massachusetts General Hospital (MGH) investigators have used a new sequencing method to identify a group of genes used by the brain’s immune cells, called microglia, to sense pathogenic organisms (bacteria that cause bacterial infection), toxins or damaged cells. Identifying these genes could lead to better understanding of the role of microglia both in normal […]

Cuts, Scrapes, and Hair Loss a Thing of the Past!

Can adults repair their tissues as easily as children can? A study currently conducted at Boston Children’s hospital is attempting to find the answer to this question. Researchers have found that by activating a gene called Lin28a, they were able to “regrow hair and repair cartilage, bone, skin and other soft tissues in a mouse […]

Dr. Light

Cardiac arrhythmia is a problem with the rate of heart beat that currently affects 4 million Americans. During arrhythmia, the heart may beat too fast, too slow, or have an obvious irregular rhythm. In some cases, this heart condition may be life-threatening with the ability to damage the brain, heart, and other organs due to […]

Possible HIV Remedy?

There wide array of deadly diseases that affect millions of people worldwide. Do you ever wonder if there could be a cure for just one? A team of researchers led by Dr. Caroline Goujon and Professor Mike Malim at the Department of Infectious Diseases in King’s College London has recognized a new gene that may […]

The damages of Sleep Loss

Roughly 30 million Americans are “just trying to catch up on their sleep.” 20% of Americans report that they get less than 6 hours of sleep on average. This nation-wide sleep loss is “taking a toll on our physical and emotional health, and on our nation’s highways.” Sleep loss leads to a variety of inconvenient issues. According […]

Genetically Modified Food? Now You Can Know For Sure.

Whole Foods Market has officially become the first grocery store to require the labeling of all genetically modified foods. In an article published by The New York Times, on Friday, March 8th, Whole Foods Market announced that they will be labeling all genetically enhanced food products. According to Whole Foods president A. C. Gallo, the […]

Genome Project Helps Connect Ethnicity to Diseases

Scientists at the Washington University School of Medicine in St. Louis have started the “1,000 Genomes Project” in which they will decode the genomes of 1,000 people from all over the world in hopes of finding genetic roots of both rare and common diseases worldwide. On October 31st, the results of DNA variations on people […]

Blondes Unite!

Despite the ‘dumb blonde’ jokes, and Danish or Dutch teases, I have enjoyed being blonde haired. As far as hair colors go, I think being blonde is perfectly suitable. However, there are certain preconceptions about hair color and race that people have. One being that people of certain ethnicities and races cannot have naturally blonde […]

Sweet Genes Not So Sweet

Do you enjoy eating foods that taste sweet? Do you also like to eat meat? Well, what would you do if you ate so much meat that your genes responsible for detecting the sweet taste suddenly stopped? Would you be upset? I certainly would be. Thankfully, humans do not have to worry about this problem […]

Identical but Not the Same

  After studying genetically inherited traits and diseases it could be easy to assume that genes determine everything about us. While it is true that colorblindness is a sex-linked trait – there is certainly more to the story. Monozygotic “identical” twins are genetically identical, so they should be the same in all ways shouldn’t they? […]

Quarter Horse? More like Million Dollar Horse! But is it all worth it?

According to the article, “How the Quarter Horse won the Rodeo” , quarter horses are known for their superior speed, agility, and tranquility.   Why are these horses so superior? According to BioMed Central’s open access journal, BMC Genomics, used sequencing to map variation in the genome of the quarter horse male. The sequencing revealed that the quarter […]

Secrets (almost) Revealed about the Evolution of Plants

Now that we are studying plants in class, and learning about different adaptations and some of the evolution of plants I thought this study would be interesting to look at. The sequencing of the genome of a plant known as spikemoss, may give scientists a better understanding of how all kinds of plants evolved over […]

Human Health in the Hands of a Naked Mole Rat?

         What do you think of when you see a naked mole rat? Do you think it is hideous because it has no fur? Do you think you would want to pet it? Whatever you think about this animal, you would never expect that it could improve human health. Who knew they […]

Always Sick? It may not be your fault

I feel like I get sick more than most of my friends. I always come up with excuses as to why I am sick like: “I must have caught it from my sister”, “I’m just really stressed” or “my lack of sleep lowers my immune systems ability to fight off infection.” But now I have […]
