Clothes can repair itself!

Washington: Coatings made from squid proteins may help clothes that could fix their own rips, a new study by the US Naval Research Laboratory has claimed. The coating may not only lead to self-healing clothes, but also help create garments tailored for protection against chemical and biological warfare and that can repair themselves.
The researchers investigated molecules from the suction cups on squid tentacles for use in self-repairing films.They focused on proteins from razor-sharp, tooth-like structures around the openings of these suction cups that help squids latch onto its prey . Previous research suggested proteins from these “squid ring teeth“ are tough and elastic under both wet and dry conditions. When a fabric covered in this coating is soaked in water, the proteins diffuse towards holes and tears in the coating, linking segments of coating and fabric together to make repairs. “We were surprised at the rapidity of the healing process and the strength of the healed materials,“ said study co-author Walter Dressick.

ELECTION – 2024 – 2029 How Formidable is Narendra Modi for opposition to Challenge! But who is Modi – Narendra Damordas Modi? A resident of Vadnagar, in north eastern Mehsana district of Gujarat where he completed his schooling. Born in Sept 1950, he started to attend the local RSS Shakha at the age of 8, where he met his future mentor Laxman Rao Inamdar. Public space informs that, he used to help his father in his tea stall in Vadnagar railway station. There appears to be some confusion on this, since it was only in 1970, the railway station was set-up in Vadnagar. But, there’s also a mention that Vadnagar had a meter guage train running since 1930, which means, there could have been some shelter which could pass-off as a railway station. At the age of 17, probably after finishing his schooling, he left home for Ramakrishna Math Ashram in Rajkot, then to Ramakrishna Ashram Belur Math in West Bengal and from there to Almora to be in Swami Vivekananda’s Ashram. Public space also info...

TEMPLE IN AYODHYA- An Overdue STATEMENT 22nd January 2024, shall mark as a very significant day in the contemporary history of India that is Bharath. It was the day the long awaited temple for Lord Rama, the Maryaada Purushottam in the Indian pantheon of God heads, was formally consecrated at Ayodhya. The ‘500 years old’ wait is over, so informs public space. It has ended the alien influence that had disturbed the national conscience from times immemorial. However belated, the temple at Ayodhya has been an unprecedented development. It’s a statement all Indians, Hindus in particular, can be comfortable to align it. Yes, this temple at Ayodhya did wipe out a historical humiliation, where an existing temple was destroyed some 500 years ago to build an alien place of worship. It was a statement then, for the alien force, only to humiliate us. Yes, at long last we could reverse it, at our own terms, within the precincts of law and order. Indeed, the temple at Ayodhya has proved that rev...
