Researchers have developed a novel smell test that is easy to use in patients with Parkinson’s and Alzheimer’s, and could also be helpful in diagnosing Covid-19.
The smell testing kit, developed by Queen Mary University of London researchers, includes capsules of aromatic oils placed between two strips of single-sided tape.

To take the smell test, the capsules are simply crushed between the fingers and the tape strip peeled to release the aroma contained within the capsules. Based on a person’s ability to recognise these smells, a score would be generated that can be sent to doctors, if they are experiencing a loss of smell.
“Our capsule-based smell test can assist in the rapid diagnostic of various diseases linked to the loss of smell. These include chronic neurological conditions such as Parkinson’s and Alzheimer’s disease, as well as Covid-19, which is known to affect the sense of smell,” said lead researcher Ahmed Ismail from Queen Mary’s School of Engineering and Materials Science.
“Being non-invasive and less stressful, the capsule-based smell test has benefits over the nose swab in diagnosing Covid-19. This is an advantage for testing children in particular, as they are typically horrified if they need to do a nose swab, and the test can be done in the comfort of their own home,” Ismail added.
The study, published in the journal Royal Society Interface, showed that, in a small group of eight patients with Parkinson’s disease, the smells from the tests were detectable.
The participants also cited the relative ease process of rupturing the capsules, particularly for those with tremors, compared to the standard scratch and sniff smell test available on the market.
Moreover, in the capsule-based smell test, “the amount of odour released is controlled by the amount of oil precisely encapsulated. The mass-production of our new test would also be cheaper than a scratch and sniff test,” Ismail noted. (IANS/GA)
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.
Celebrity chef, Sanjeev Kapoor, strongly advocates this need of eating seasonal produce. He says, "The beauty of our food is in our seasonal usage of fruits and vegetables. If you realise, Gajar ka halwa is made aplenty during winters as this is the season when beautiful red carrots hit the market or mango pickle is made during summer, thanks to its availability. Despite people and sometimes, even me, suggesting that we should eat fresh as well as seasonal fruits and vegetables, we do not know what chemicals are sprayed on them to keep them safe while they are growing. When this produce hits the market, there isn't a certifying agency like the FSSAI that will help people understand what vegetables and fruits are free of pesticides and germs and which ones don't. Hence, the onus lies on us to make them safe for consumption. ITC's Nimwash is a good solution."
When it comes to winters, the Chef recommends eating these fruit and vegetables:
* Purple Mogri -- Mogri or Radish pods are not a common sight throughout the country. But you can spot them during the winters in local markets in northern India where women pick them up to make raitas, curries and stir fries. Rich in magnesium, calcium and copper, the vegetable is known to aid people from digestive problems.

* Sweet Potato -- A re-discovered favourite, Sweet potatoes have created a space for itself in the millennial kitchen. With its diverse addition in burgers, chips and even chat, the root vegetable is filled with nutrients such as fibres and vitamins.

* Avarekalu -- Called Hyacinth beans in English, Avarekalu is a winter speciality in the south that is added to sambhar, saagu, rotis, etc. Bangalore is famed for its Averakalu mela during the winter months, where you can find these beans in dosas, Pani puri and even Jalebis! Thronged by crowds from all over the city, the food fest is a gourmand's delight.

* Amla -- The Indian gooseberry is a common winter fruit found through the country. High in Vitamin C, it is known to be immunity building and extremely beneficial for the skin and hair. There are multiple ways to eat Amla -- it is pickled, made into a fruit preserve called as Murraba or even eaten by sprinkling salt over it.

Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a new study. The study, published in the journal Scientific Reports, found there was, on average, a 17 per cent improvement in participants' colour contrast vision when exposed to three minutes of 670 nanometre (long wavelength) deep red light in the morning and the effects of this single exposure lasted for at least a week.
However, when the same test was conducted in the afternoon, no improvement was seen. "We demonstrate that one single exposure to long wave deep red light in the morning can significantly improve declining vision, which is a major health and wellbeing issue, affecting millions of people globally," said lead author, Glen Jeffery from the University College London.

For the study, the team involved a small yet significant number of participants aged between 34 and 70, had no ocular disease, completed a questionnaire regarding eye health prior to testing, and had normal colour vision (cone function). This was assessed using a 'Chroma Test' -- identifying coloured letters that had very low contrast and appeared increasingly blurred, a process called colour contrast.
Using a provided LED device, all participants were exposed to three minutes of 670nm deep red light in the morning between 8 a.m. and 9 a.m. Their colour vision was then tested again three hours post exposure and 10 of the participants were also tested one week post exposure. On average there was a 'significant' 17 per cent improvement in colour vision, which lasted a week in tested participants; in some older participants, there was a 20 per cent improvement, also lasting a week.
A few months on from the first test (ensuring any positive effects of the deep red light had been 'washed out') few participants, carried out the same test in the afternoon, between 12 p.m. to 1 p.m. When participants then had their colour vision tested again, it showed zero improvement.
