NUS team develops cheap, portable test kit for quick screening of diseases

Source: channelnewsasia

A team of researchers from the National University of Singapore (NUS) has developed a new test kit that is able to screen for multiple diseases in less than an hour, and for under S$1.

The portable test kit – about 4cm in length and 3cm wide – is designed to detect a wide range of diseases. They range from Zika and Ebola to hepatitis, dengue and malaria, said NUS in a media release on Tuesday (Sep 18).

It can also detect various types of cancers and genetic diseases.

Olive oil may be better than viagra

According to a new study, adding at least nine tablespoons to your diet per week could prove as effective as - if not more effective than - Viagra in treating erectile dysfunction (ED). Who would have guessed?!

The study, led by cardiologist Christina Chrysohoou at the University of Athens School of Medicine in Greece, looked at 660 men who averaged 67 years old. Some ate a Mediterranean diet - eating a robust amount of fish, nuts, fruits, vegetables, legumes, and of course, olive oil - and those who did, reduced their incidence of ED by up to 40%. That nine tablespoons per day translated to elevated testosterone levels, which can help restore phallic functioning.

But that is just part of olive oil's penis magic. While viagra boosts performance for a few hours window only, olive oil's beneficial effects may last months or years.


Synthetic sandalwood can treat baldness

Image for illustration only
New research shows that human hair follicles express an olfactory receptor of their own called OR2AT4, and when OR2AT4 comes into contact with the molecular structure of a specific scent –synthetic sandalwood, as it turns out – it stimulates hair growth.

In other words, your hair – or rather your hair follicles – can 'smell', and if they sniff out the right chemical, it could be a radical new way of preventing hair loss.

This is the first time that smell is proven to be a strong stimulant.

Another reason for using synthetic sandalwood is because the natural sandalwood oil is the most expensive essential oil and also its oil does not bind well with the receptor, unlike synthetic sandalwood oil.

Scientists discover why hair turns gray and goes bald

This is old news, about 1 and a quarter years old late. But it is still good news for those who are bald.

Here is what is going on when researchers accidentally stumbled upon this answer when they were studying about cancer tumours on mice:

A specific protein called KROX20 turns on in skin cells, which becomes the hair shaft. This triggers the production of another protein called stem cell factor (SCF).

When the scientists deleted KROX20 in mice, they became bald. And when they deleted the SCF gene, the mice’s hair turned gray, and then whitened as they aged.

Hopefully soon, the researchers should have more answers since they have pinpointed the actual genes that cause grey hair and baldness.
