Every surface of our body – inside and out – is covered in microorganisms: bacteria, viruses, fungi and many other microscopic life forms. vrx/Shutterstock.com

Meet the trillions of viruses that make up your virome

Just because you don't have the flu doesn't mean that your aren't teeming with viruses inside and out. But what are all these viruses doing, if they aren't making you sick?
Breast cancer type 1 (BRCA1) is a human tumor suppressor gene, found in all humans. Its protein, also called by the synonym BRCA1, is responsible for repairing DNA. ibreakstock/Shutterstock.com

Gene-editing technique CRISPR identifies dangerous breast cancer mutations

Mutations in BRCA genes are linked to the early onset of breast and ovarian cancers. But the effect of most mutations is unclear. Now new research can distinguish harmless from dangerous mutations.
More than 3.9 billion people live in regions where the Aedes aegypti mosquito is present. This species transmits Zika, dengue, chikungunya, and yellow fever. mycteria/Shutterstock.com

Genetically modified mosquitoes may be best weapon for curbing disease transmission

For several billion people mosquitoes are more than a nuisance -- they transmit deadly diseases. Now genetic modification may prove the most effective defense against the mosquito, preventing disease.

Funding basic research plays the long game for future payoffs

Basic research can be easy to mock as pointless and wasteful of resources. But it's very often the foundation for future innovation – even in ways the original scientists couldn't have imagined.

Here’s what we know about CRISPR safety – and reports of ‘genome vandalism’

CRISPR has been hailed as the an editing tool that can delete inherited mutations and cure disease. But recent papers suggest that the technique may be too dangerous for use in human therapies.
The lighter citrus plants have been edited using CRISPR to alter the phytoene desaturase (PDS) gene which gives them a white color. Yi Li

These CRISPR-modified crops don’t count as GMOs

GMO crops have been rejected by many countries and consumers. Now, an international team of researchers are creating better crops using DNA editing--without inserting foreign genes into the plant.
Scientists discovered some bacteria can cut the DNA of invading viruses as a defence mechanism. They realised they could use this to cut human DNA.

What is CRISPR gene editing, and how does it work?

CRISPR harnesses the natural defence mechanisms of some bacteria to cut human DNA strands. Then the DNA strand either heals itself or we inject new DNA to mend the gap. This is gene editing.
From biotech to climate change, advances in technology raise significant moral questions. To engage responsibly, our next generation of scientists need training in the arts and ethics. (Shutterstock)

STEAM not STEM: Why scientists need arts training

Universities must train scientists to engage with the ethics of emerging technologies, rather than functioning as cogs in the engine of economic development. Integrating the arts into STEM can help.
Can technology be tamed? Or have we already lost complete control? Tom Simpson

What can be done about our modern-day Frankensteins?

Much like the fictitious Victor Frankenstein in Mary Shelley's novel, more and more scientists are running away from their real-life creations.
Only one Canadian researcher has ever received the Nobel Prize for medicine, for the discovery of insulin in 1923. And yet Canadians have been essential to developments in stem cell research, gene sequencing and treatments for cancer and brain trauma. (Shutterstock)

Why can’t Canada win another Nobel Prize in medicine?

Only one Canadian has ever received the Nobel Prize for medicine, in 1923. But Canadian discoveries have been essential to stem cell research, gene sequencing and treatments for cancer.
