NUS scientists produce probiotic drink from soya waste

Scientists at the National University of Singapore (NUS) have found a way to turn okara - the residue from the production of soya milk and tofu - into a nutritious probiotic drink.

Every year, about 10,000 tonnes of okara are produced, of which about 80 per cent are generally discarded as food waste due to its unpleasant taste and smell.

To reduce this waste, NUS scientists spent one year tweaking a recipe that experimented with 10 different yeasts and four different enzymes before coming up with their ideal recipe.

Unlike many commercially available probiotic drinks, which are mainly dairy-based and require refrigeration, NUS' creation can be stored at room temperature for up to six weeks.

Researchers are still fine-tuning the recipe and expect it to be commercialised in about 12 to 18 months.

Scientists discover how to CONVERT types A and B into O

Scientists claim they may have identified gut bacteria that could convert blood types A and B into type O.

People with type O-negative blood are known as universal donors, meaning they can give to anyone with any blood type.

This is why people with this blood type are always in high demand in medical emergencies and natural disasters.

Researchers, from the University in British Columbia in Canada, however, say they've discovered an enzyme found in the human gut that could covert other blood types in type O - potentially putting an end to the massive blood shortage.

Forum: Riders, not PMDs, are the problem

The Active Mobility Advisory Panel's recommendations make a mockery of the car-lite society that we are envisaging.

While I understand that accidents caused by reckless and inconsiderate riders are causing distress to pedestrians, the solution is to tackle the source of the problem, which is the rider and not the personal mobility devices (PMDs) themselves.

I would recommend that an age limit of 21 be set for PMD riders.

The riders should also not be allowed to ride together with another person. Riders should also be licensed before being able to purchase and ride a PMD.

The licensing model could be similar to that for drivers in which they are required to take basic and advanced theory tests as well as a practical one.

This would leave the riders with no excuse to claim ignorance about the rules governing the use of PMDs.

The panel should find a balance between pedestrians and PMD users, and not lean to either side.

Smartphone could be covered in up to TEN times as much bacteria as a toilet seat

Image for illustration only

Researchers took swabs from an iPhone 6, Samsung Galaxy 8 and Google Pixel to test for the levels of aerobic bacteria, yeast and mold present.

For all three phones, the screens had the highest levels of bacteria, with 100 CFU (colony forming units) per cm2 for the Samsung Galaxy, 40 CFU for the iPhone, and 12 CFU for the Google Pixel.

This is compared to 5 CFU per cm2 of yeast and bacteria on an office keyboard and mouse, and 24 CFU on a toilet seat and flush.

Meanwhile, the study found that a beauty blender had 24 CFU per cm2, while a make-up brush had 0.4 CFU with high levels of mold.
