How Your Morning Commute Resembles a Fungus


In many fungi, the DNA storage compartments called nuclei are not prisoners of the cells they reside in, the way they are in animals and plants. Instead, fungal nuclei are free to move about the cabin. They flow through the joined, tube-shaped cells of fungi like busy commuters, and experience many of the same dynamics. [...]

The Hallmarks of Cancer 9: Reprogramming Energy Metabolism

Cancer cells consume more glucose than normal cells. This is exploited when imaging cancer. Positron Emission Tomography (PET) combined with Computer Tomography (PET/CT) is used to detect the absorption of the glucose analogue fluorodeoxyglucose (FDG) by tumours. In this image, besides the normal accumulation of the FDG molecule in the heart, bladder, kidneys, and brain, liver metastases of a colorectal tumor are visible in the abdominal region.

The Hallmarks of Cancer are ten underlying principles shared by all cancers. You can read the first eight Hallmarks of Cancer articles here. The ninth Hallmark of Cancer is defined as “Reprogramming Energy Metabolism”. Uncontrolled growth defines cancer. Growth requires a cancer’s cells to replicate all of their cellular components; their DNA, RNA, proteins and [...]

Hallmarks of Cancer 7: Genome Instability and Mutation

BRCA1 structure

All cancers share ten underlying principles, also known as the Hallmarks of Cancer. You can read about the first six here. The seventh is defined as genome instability and mutation. Cancer Cells Evolve Not all cancer cells are equal. They vary, they compete, and the fittest survive to pass on their genes to daughter cells, [...]

Print It: 3-D Bio-Printing Makes Better Regenerative Implants

3-d bio-printing tissue scaffold cells

Desktop 3-D printers can already pump out a toy trinket, gear set or even parts to make another printer. Medical researchers are also taking advantage of this accelerating technology to expand their options for regenerative medicine. Brian Derby, of the School of Materials at the University of Manchester in England, details the advances and challenges [...]

Cell phone emissions change brain metabolism

man on cell phone, brain activity metabolism change

Cell phones have not been convincingly linked to brain cancer, but that doesn’t mean that their associated radiation has no effect on our bodies. A new study shows that these pervasive devices can alter the brain’s glucose metabolism, a marker of neuronal activity. The findings will be published in the February 23 issue of JAMA, [...]

Watching grass grow gets exciting: New videos show plants’ cellular development

3-d video capture of cellular plant growth division to form a bud

Throughout their growth cycle, plants sprout all kinds of intricate and complex structures that range from scarcely apparent to invisible in the seedling stage. Leaves, flowers and seeds can appear, seemingly out of nowhere, from a smooth stem or branch. But the details of how cellular development occurs—why one cell might give rise to petal [...]

Bleed Pretty Cells: interview with Michele Banks


Public spaces like national galleries have created a perception that art can be understood and appreciated by anyone, while the fine art world itself has grown ever-more self-referential and obscure to outsiders. Here on Symbiartic, we sometimes cover artwork that’s accessible to a specific audience, rather than everyone and no one.  Artwork that speaks, evokes, and moves the [...]
