A team of US engineers have developed a prototype wearable device that can continuously collect live cancer cells directly from a patient’s blood in an advance that could help patients avoid biopsy as well as get treatment for cancer more effectively.
Most cancer cells cannot survive in the bloodstream, but those that do are more likely to start a new tumour.
Typically, it is these satellite tumours, called metastases, which are deadly, rather than the original tumour. They can release more than 1,000 cancer cells into the bloodstream in a single minute.
This means cancer cells captured from blood could provide better information for planning treatments than those from a conventional biopsy, the researchers explained.
“Nobody wants to have a biopsy. If we could get enough cancer cells from the blood, we could use them to learn about the tumour biology and direct care for the patients. That’s the excitement of why we’re doing this,” said Daniel F. Hayes, Professor at the University of Michigan.
The wearable device contains a cell-grabbing chip, which in animal tests trapped 3.5 times as many cancer cells per millilitre of blood as it did running samples collected by a blood draw, according to the paper published in the journal Nature Communications.
The chip uses nanomaterial graphene oxide to create dense forests of antibody-tipped molecular chains, enabling it to trap more than 80 per cent of the cancer cells in the blood that flows across it.
It can also be used to grow the captured cancer cells, producing larger samples for further analysis.
The team estimates the device could begin human trials in three to five years. It would be used to help optimise treatments for human cancers by enabling doctors to see if the cancer cells are making the molecules that serve as targets for many newer cancer drugs. (IANS)
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.

Jammu and surrounding areas are sensitive in terms of the strategic importance. Some months ago, there was an attack on an Army installation using drones. Will the 'drones for vaccines' be permitted in such a case? Allaying fears, a top official from the Ministry of S&T said, "The drones would be deployed by authorised agencies such as hospitals, not anybody can use it, nor would any random person be permitted to use it."
NAL has called the drone as 'Octacopter' and it can fly at an operational altitude of 500 m AGL and at maximum flying speed of 36 kmph. It can be used for a variety of BVLOS applications for last mile delivery like medicines, vaccines, food, postal packets, Human organs (such as heart for heart transplantation) etc. NAL Octacopter is integrated with a powerful on-board embedded computer and latest generation sensors for versatile applications like agricultural pesticide spraying, crop monitoring, mining survey, magnetic geo survey mapping etc., S&T officials had said.

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.
