Indian entrepreneur develops device to detect hearing inability in babies

Neeti Kailas, a Bangalore-based woman entrepreneur, has designed a non-invasive device to detect hearing inability in babies. This battery operated device can detect hearing inability by measuring auditory brain-stem response (ABR). Strap it on to the baby’s head just like a headband and it will read responses from the auditory system of the brain when activated. The product is indigenous and cheaper than many hearing-loss detecting devices presently available in the market.  Kailas, director and co-founder, Sohum Innovation Lab, has also won the 2014 Rolex Award for Enterprise. The product is expected to be marketed by 2016.

As per available medical data, around 150,000 hearing-impaired babies are born in India. If the hearing inability is detected well on time then difficulties in learning speech, language and cognition can be prevented to a great extent.

Permanent hair dye may have carcinogenic chemicals: says Research

Hair salons may be using banned aromatic amines called toluidines for treatments like permanent hair dye and perming, which has chemicals with carcinogenic properties, as per a research from Sweden’s Lund University. The research proves that oxidative or permanent dies are absolutely unsafe. Level of o-toluidine (ortho-toluidine) has been determined in 32 normal hair dye users, 295 female hair dressers and 60 people who have never used these products, and it was found to have been causing cancer. It is recommended that hair dressers must wear gloves, while performing the task of hair dyeing.

Wasps give insight into robotic surgery

The Indian Institute of Science may soon develop a novel technique for robotic surgery. The inspiration for this comes from observing the life cycle of wasps, as per media reports. The researchers at IISc have discovered that wasps lay eggs on fruits by sawing into them with the help of their egg-laying parts. Further study revealed these parts to have teeth that resemble that of a saw, and a fine coating of zinc that lends hardness. Wasps thus create a natural drilling machine of sorts, which can be replicated in surgery robots. The finding was published in the institute's Journal of Experimental Biology.
