A water-proof drone is being used by Australian scientists to collect the highly-treasured nasal mucus of migrating whales. The snot is rich with fresh DNA, viruses and bacteria, and is collected by a drone that hovers over the blowholes of humpback whales as they embark on their epic annual journey along Australia’s east coast.

Whales, like all mammals need air, and come to the surface to breathe through a blowhole. Vanessa Pirotta, a marine biologist at Macquarie University, says that nasal mucus indicates the health of the whale.


“It is the juicy biological mixture that you see as a whale takes a breath as they surface from the water,” she said. “You often see that plume and it sounds like this like [sounds of sharp breaths] as a whale breathes because, after all, they are mammals like you and I and they have two nostrils, and it is the humpback whale that I am talking about. So as they take a breath it is a lot of lung bacteria coming out from their lungs, which we can collect to provide a snapshot of whale health.”

Australian researchers have attached a petri dish that is used in scientific tests to a drone which flies through the whale’s nasal mist.

“As a whale comes to take a breath — you can actually see it coming to the surface on really good weather days that is — the drone then lowers, the petri dish is then opened and the drone is flown through the densest part of the whale snot, collecting the sample in the petri dish. Now once this happens the lid is shut and the drone is flown back to the research vessel and we collect the sample to later process it in the laboratory,” said Pirotta.

The research could help to solve one of the mysteries of another magnificent creature of the deep — the Southern right whale. Its numbers have recovered on Australia’s west coast since hunting was outlawed but its population on the eastern seaboard remains stubbornly low.

In the past studies into whale health had to rely on examining whales that were either killed or those whales that had been stranded on a beach. Drones allow scientists to collect samples from free-swimming whales to gather information in a safe and non-invasive way. (VOA)

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday with a focus on vaccines delivery initially. "This is going to be a pilot project for the area. The drone is developed and manufactured entirely by our scientists," Union Minister for Science & Technology, Dr Jitendra Singh told mediapersons. Singh said he himself will be launching the project at Jammu.

The drone is developed by the scientists at Bengaluru's National Aerospace Laboratories (NAL), a constituent of Council of Scientific and Industrial Research (CSIR), an autonomous Society that is headed by the Prime Minister. For now, the delivery would be limited to Covid vaccines and once successful, it would be expanded to be used for regular delivery of medicines in the remote, hilly areas.

According to him Amitabh Bachchan is a great actor in the industry.

Bollywood actor Abhishek Bachchan shares how he feels when people compare him with his father Amitabh Bachchan on the singing reality show 'Sa Re Ga Ma Pa'. He also requests contestant Rajshree Bag to sing a track 'Bahon Mein Chale Aao' featuring his mother Jaya Bachchan.

Abhishek said after looking at the performance of Rajshree, who is often compared with Lata Mangeshkar on the show, that she reminds him of being compared with his father. "Rajshree, whenever I have got the chance to watch the show, I've seen people compare you to Lata didi. It actually reminded me about how people compare me with my father and ask me how I feel about it."

According to him Amitabh Bachchan is a great actor in the industry and this is what he says to everyone making these comparisons. "My answer to them is that there's no greater actor in this film industry than Amitabh Bachchan and if I'm being compared to him, I am sure I must have done something good."

"Similarly, your voice has a different kind of magic like Lata ji and that's why people are comparing your voice with her. I feel you should always take this as a compliment," he concluded. 'Sa Re Ga Ma Pa' airs on Saturday and Sunday on Zee TV. (IANS/ MBI)

Winters in India have always beckoned for that hot, steaming bowl of tomato and pepper rasam or the mellow, millet based Raab. Certain dishes like sarson ka saag, undhiyu, nimona pulao are winter specialites in the country. Seasonal food has always been an Indian speciality -- we switch our choice in fruits, vegetables, sometimes even grains with the onset of different season. The preference of using specific ingredients during certain climates is visible in our sweets as well. It's common to find local and traditional delicacies made of jaggery, instead of sugar during the winters. Case in point -- the Nolen Gur Rasgulla, a speciality made in Odisha and West Bengal between November to February.
