Smart Knife Sniffs Out Cancer

Chemists at Imperial College London turn heads with a new type of diagnostic tool. Electrosurgical knives or “flesh vaporizers” (far cooler sounding) get an upgrade which eliminates need for pathology labs. The iKnife cuts its way forward in diagnostic technology, offering surgeons a reliable method for detecting cancer in real-time. Gas emitted from the superheated […]

Bacterial influence: Microbes shape evolution

Bacterial influence: Microbes shape evolution

Bacteria are important, there are 10 times as many bacterial cells in or on a human than there are human cells, and they have ways of making their presence known. The collection of microscopic critters living in and on you is known as the “microbiome”, and they can play huge roles in human survival. The […]

More than a single genome: How alike are your cells?

As hard as it may be to believe, every human starts out as a single cell (around one two-hundredth of an inch in size) formed when the right sperm cell meets the ovum in the mother. The sperm and egg each carry a half-set of chromosomes, merging to create a single genome that is a […]

The genetics of smell: Making sense of scents.

11 November 2013

Smell is a very important sense for mammals; many people regard it as a fairly useless scent, but it has many, many uses. Flavor is highly dependent on smell, not to mention the ability to detect potential toxins, or to find compatible mates, smell is very important for everyday life. What makes smell fascinating is […]

Are cancers a cellular “safe mode”? Why do these diseases exist?

Are cancers a cellular “safe mode”? Why do these diseases exist?

18 July 2013

Cancers are an ancient disease, so ancient in fact, that many of the genes associated with human cancers are also found in the humble sea sponge, the most basic of all animals. Such a distant relationship makes one question: is cancer necessary for animal life? As pointed out before on BioMedicalBlog, cancerous cells are unlike any other […]
