The brain is arguably the most complex organ in the human body and understanding its structure could help explain a fundamental mystery of human existence: consciousness. The brain is composed of billions of specialized cells called neurons, which communicate with each other via electrical and chemical signals. Neurons are responsible for processes ranging from vital life functions to the ability to walk, talk remember, … Continue reading One Neuron to Rule Them All?
The Church lab at Harvard University recently announced plans to create a hybrid mammoth and elephant. Using a technology called CRISPR, researchers in the Church lab have learned how to insert mammoth DNA into the cells of modern elephants. Theoretically, this could set the stage for developing an embryo with DNA from both a modern elephant and the woolly mammoth. The group would like to … Continue reading Could Woolly Mammoths Walk Again?
The adaptation of the opportunistic human pathogen Pseudomonas aeruginosa often produces phenotypic diversity. Here, mutants isolated from a genetic screen show notable differences in phenotype: the production of pigments, size, shape, and texture. The blue-green pigmentation seen in some mutants results from the production of pyocyanin, an excreted toxin that kills other microbes and mammalian cells. Whereas, the brown pigmentation is caused by the exocellular pigment, pyomelanin, which … Continue reading Pseudomonads I
What you’re seeing is the brain of an axolotl, an organism known for its ability to regenerate many organs including the limb, heart, and spinal cord. The different colors (blue, green, red) represent some of the neuronal cell types present within the brain. Incredibly, when this region of the brain is injured, the brain regenerates with fidelity, and all of these cell types are remade. … Continue reading Neuronal Diversity of the Axolotl Brain
Chemotherapy is a common and dangerous cancer treatment due to the negative effects on everything that is not a tumor cell. Researchers from Columbia University have invented a soft medical implant capable of administering drugs from inside the body. The ability to place this device close to the target area allows for a significant (90%) reduction of the drug dosage to be used. Similarly, avoiding body-wide administration of the drug can greatly reduce the damage inflicted by normal chemotherapy dosages. Continue reading A new medical implant might greatly reduce the risk of chemotherapy treatment
According to the CDC, 70.7% of the US population is overweight or obese (BMI>30), with 37.9% being obese. Obesity related health expenses accounted for an estimated $147 billion in healthcare spending in 2008 alone. The dire health consequences for obese individuals include higher incidence of high blood pressure, type 2 diabetes and coronary heart disease to name a few on top of overall decrease in … Continue reading Parental weight and its impact on early childhood development
The intricate network of blood microcirculation in the human body is a closed and complex one. The hierarchy of blood flow in the human body takes blood from the heart to deep organs systems, through arteries that branch out into smaller arterioles and later into microscopic capillaries. Presented here is a pseudo colored montage of images taken and combined from different magnifications that represent a … Continue reading The Blood Flow Border Patrol
