A new prototype device can now be used to immediately identify airborne hazards, allow real-time monitoring of air quality during haze outbreaks and assist in the detection of industrial gas leaks.

The device, which was developed by a team of scientists from Nanyang Technological University (NTU), can replace current laboratory methods of identifying gases in the air which takes between a few hours and days to obtain results.

“Emergency scenarios require a fast and ongoing analysis of potential air contamination, such as following a natural disaster, chemical spill or illegal dumping of toxic waste, so that emergency responders can take appropriate action,” the university said in a press release on Tuesday (Oct 15).

Forum: Motorists continue to impede emergency vehicles

I live in a mature Housing Board estate overlooking an open-air carpark.

Last Saturday at about 11am, I witnessed the selfishness of Singaporean motorists first-hand.

A Singapore Civil Defence Force Hope ambulance entered the carpark. I heard its siren wailing long before it reached my block.

In the carpark, cars were waiting for parking spaces next to double-yellow lines, and other vehicles were waiting for those in front of them to move. A few impatient drivers were trying to squeeze through whatever little space was available, creating further congestion. One driver was even reversing into a space right in front of the ambulance.

All these led to one thing - impeding the progress of the ambulance.

At one point, the ambulance driver had to exit his vehicle and order the motorists to move and give him room.

There are many old and sick residents in my estate, and I have heard of this same scenario playing out several times.

This also happens on the roads. One ambulance driver told me that this happens "all the time".

I have noticed this happening for fire engines as well.

Sirens are loud enough to be heard from far away, giving drivers enough time to filter and clear the lane.

But other selfish drivers may not allow others to filter in.

Clearly, the penalties are not tough enough to end this kind of behaviour.

In countries like Australia, clear-thinking, fast-acting and considerate drivers exercise gracious manners and civic-consciousness on their roads, which deserves applause.

Some benefits of regular ejaculation? Better sleep and enhanced immunity system

According to consultant urologist Professor Dr George Lee Eng Geap, the scientific basis of ejaculation benefits is associated with the elevation of certain feel-good neurotransmitters in the brain during orgasm.

“The feel good factor is believed to have the impact of stress reduction, some even associate frequent ejaculation with increase in motivation and productive attitude,” he said.

He added that the correlation of frequent ejaculation with improved sleep, enhanced immunity and fertility is well documented in the literature.

Citing the Harvard ejaculation scientific data, he said the study revealed that frequent ejaculation (21 times or more per month) is associated with a 31% reduction in prostate cancer risk when compared with men who ejaculated between four to seven times a month.

My 2 cents:
There are some sayings that sperms and eggs are essence of life. Therefore, one's life is reduced when one produces sperms or eggs. Hence women outlive men because after menopause, women do not produce egg anymore where else men still produce sperms late into their lives, hence shortening their lives.
