Scientists “hacked” the genetic code of brewer’s yeast to produce cannabis compounds. They inserted genes from cannabis plants into the yeast’s genetic code which allowed it to produce CBD and THC. Their end goal is to allow large scale cannabinoid production without cultivation.

Scientists brew cannabis using hacked beer yeast The yeast that people have used for millennia to brew alcoholic drinks has now been engineered to produce cannabinoids — chemicals with medicinal and sometimes mind-altering properties found in cannabis. The feat1, described on 27 February in Nature, turns a sugar in brewer’s yeast (Saccharomyces cerevisiae) called galactose …

Did Dr. Edwin Chandross Know His Discovery Was Popular Among the Younger Generation?

If you are familiar with glowsticks, you’d also know that the contents that make the “glow” result from a chemical reaction between a fluorescent dye and other compounds. But did you know that the man behind the chemiluminescent liquid had no idea how famous his discovery was? Dr. Edwin Chandross found the chemical reaction of …

Alexander Fleming’s mold could not produce penicillin fast enough for mass production; it wasn’t until 15 years later that lab worker ‘Mouldy’ Mary Hunt tested a moldy cantaloupe in a grocery store and discovered the strain that is used to produce all penicillin today

Mouldy Mary and the Cantaloupe It’s a well known story and example of medical serendipity. Alexander Fleming (1881-1955) a Scottish microbiologist who returned to his laboratory following his summer holiday and found his growth plates of Staphylococcal bacteria had been contaminated with mould. Wherever the mould was growing the bacterial cells had been killed. Antibiotics …

A lab study found honeybee venom (which has the compound “melittin”) destroyed 2 types of hard to treat breast cancer cells. Melittin on its own reduced cancer cell growth & can be produced synthetically. One venom concentration killed cancer cells within 1 hour with minimal harm to other cells.

Honeybee venom ‘kills some breast cancer cells’ Getty Images Australian scientists say the venom from honeybees has been found to destroy aggressive breast cancer cells in a lab setting. The venom – and a compound in it called melittin – were used against two cancer types which are hard to treat: triple-negative and HER2-enriched. The …

Irène Curie and her husband received a Nobel Prize for their discovery of artificial radioactivity, 30 years after Irène’s parents received their Nobel Prize. She died due to overexposure to radiation, also just like her parents. Her children are still alive and are also prominent scientists.

Irène Joliot-Curie Irène and Marie Curie in 1925 As she neared the end of her doctorate in 1924, Irène Curie was asked to teach the precision laboratory techniques required for radiochemical research to the young chemical engineer Frédéric Joliot, whom she would later wed. From 1928 Joliot-Curie and her husband Frédéric combined their research efforts …

30 years ago you had 15-17 minutes to escape a house fire. Nowadays you only have 3-5 minutes (due to more plastics & petroleum-based products in the house as well as more open floor plans, bigger rooms, & higher ceilings).

How Much Time Do You Have To Escape a House Fire? It’s Much Less Than You Think. The amount of time you have to escape a house fire has greatly decreased in the past few decades: 30 years ago you had about 15 to 17 minutes to escape a house fire. Today, you have about …

Our brains do not necessarily process everything as that would be an overload of information, a study from 2016 found that under the influence of LSD, the brain recruited many more regions for visual processing than normal, enriching the images people saw even when their eyes were shut.

Study shows how LSD interferes with brain’s signalling A group of volunteers who took a trip in the name of science have helped researchers uncover how LSD messes with activity in the brain to induce an altered state of consciousness. Brain scans of individuals high on the drug revealed that the chemical allows parts of …

Romans weaved asbestos fibers into a cloth-like material that was then sewn into tablecloths and napkins. These cloths were cleaned by throwing them into a blistering fire, from which they came out unharmed and whiter than when they went in.

History of Asbestos The fireproofing properties of asbestos made it essential to many industries such as the automobile, construction, manufacturing, power and chemical industries. The U.S. armed forces also used asbestos to prevent fires in every branch of the military. The primary intention of using asbestos was to protect workers, but many asbestos product manufacturers …
