Can we program bacteria to fight cancer?

Cancer occurs when normal functions of cells are altered, causing them to rapidly multiply and form growths called tumours. Treatments like radiation, chemotherapy, and immunotherapy attempt to kill malignant cells, but can affect the entire body and disrupt healthy tissues in the process. In 1884 a patient had a rapidly growing cancer in his neck, it grew larger and larger. The patient then came down with an unrelated bacterial skin infection. Surprisingly as he recovered from the infection, cancer also began to recede. When a physician named William Coley tracked the patient down 7 years later, no visible signs of cancer remained. Coley believed that the bacterial infection had stimulated the patient’s immune system to fight off cancer, hence decreasing the size of the tumour. This lead to the discovery of the intentional injection of bacteria to successfully treat cancer, which was pioneered by Coley. Synthetic biologists have found a way to use disease-causing creatures by prog...

Can a Website Predict How Long You will Live?

Humans are like time bombs they have limited time on earth. The are a lot of predictions on the length of human life depending on health and age and other such factors. Young.AI is a new product in beta testing face the uses artificial intelligence (A.I.) to predict a lifespan by tracking the age of our existence in order to derive a biological age hence finding out our lifespan. Young.AI is a project of Insilico Medicine whose aim is to use “Artificial Intelligence For Drug Discovery, Biomarker Development & Aging Research.” This followed possibly the largest analysis conducted in the longevity field and produced a model using “several deep learning-based predictors of biological age trained upon population-specific blood biochemistry and haematological cell count datasets.” that was published in the Journal of Gerontology. "today, thanks to A.I. and the incredibly fast computational power of our deep learning neural networks, we can discover patterns and formulas i...

Are we always crying?

Usually, when you think of crying you think of a really sad situation or a scenario that makes us emotional. Emotional Tears are just one type of tear we shed. We are actually always crying, just with different types of tears.  Humans actually cry 3 different types of tears.  In order to understand our tears, we must understand our eye. We have special glands called Lacrimal glands in our eyes to make our tears and special tubes called lacrimal puncta to drain them away. We cry so much that we go through 132 kg of tears a year. The first type of tears, basal tears are constantly produced. They form a thin coat consisting of 3 layers that keep the iris protected. First is the mucus layer, that fastens the iris. On top of this is the aqueous layer that keeps the iris hydrated. It also repels pathogens and bacteria from damaging the cornea. The top-most layer is the lipid layer that – an oily outer film that prevents the evaporation of the other layers and is clear so...
