Your canine friend can use its highly evolved sense of smell to pick out blood samples from people with cancer with almost 97 per cent accuracy, a finding that can lead to new low-cost and non-invasive screening approaches for the disease, finds a study.

Dogs have smell receptors 10,000 times more accurate than humans’, making them highly sensitive to odours we can not perceive.


“Although there is no cure for cancer, early detection offers the best hope,” said lead researcher Heather Junqueira, at BioScentDx, a US-based healthcare company. “A highly sensitive test for detecting cancer could save thousands of lives and change the way the disease is treated,” he said.

For the study, the team used a form of clicker training to teach four beagles to distinguish between normal blood serum and samples from patients with malignant lung cancer.

Although one beagle — aptly named Snuggles — was unmotivated to perform, the other three correctly identified lung cancer samples 96.7 per cent times and normal samples 97.5 per cent times.

“This work is very exciting because it paves the way for further research along two paths, both of which could lead to new cancer-detection tools,” said Junqueira.

“One is using canine scent detection as a screening method for cancers, and the other would be to determine the biologic compounds the dogs detect and then design cancer-screening tests based on those compounds,” he said.

The results will be presented at the American Society for Biochemistry and Molecular Biology annual meeting in Florida. The team plans to use canine scent detection to develop a non-invasive way of screening for cancer and other life-threatening diseases. (IANS)

Pickles bottled in various combinations

India is known for its pickles, popularly called 'Achaar', even across the world. But who thought about the idea of pickles in the first place? Apparently, the idea of making pickles first came from the ancient civilisation of Mesopotamia, where archaeologists have found evidence of cucumbers being soaked in vinegar. This was done to preserve it, but the practice has spread all over the world today, that pickles mean so much more than just preserved vegetables.

In India, the idea of pickle has nothing to do with preservation, rather pickle is a side dish that adds flavour and taste to almost anything. In Punjab, parathas are served with pickle; in the south, pickle and curd rice is a household favourite, and in Andhra, it is a staple, eaten with everything. The flavour profile of pickles in each state is naturally different, suited to each cuisine's taste. Pickles are soaked in oil and salt for at least a month, mixed with spices and stored all year round. Mango season is often synonymous with pickle season as a majority of Indians love mango pickle. In the coastal cities, pickles are even made out of fish and prawns.

Spiral bound notebooks allow writers to easily access each part of the page

It is impossible to detail the history of bookbinding without understanding the need for it. A very useful, and yet simple invention, spiral coils that hold books together and allow mobile access to the user came about just before WWII, but much before that, paper underwent a massive change in production technique.

Beginning in China, paper was made of bamboo sticks slit open and flattened. In Egypt, papyrus was made from the reeds that grew in the Nile. In India, long, rectangular strips of palm leaves were stitched together to form legible documents. When monasteries were established, scrolls came into being. Parchment paper, or animal hide, also known as vellum, were used to copy out texts periodically to preserve them. Prior to all this, clay tablets were used to record important events, and in some cases, rock edicts were made.

By N. Lothungbeni Humtsoe

To keep the value and quality of what you offer, whether it's a romantic breakfast in bed or a royal wedding gift that will be remembered for years. The concept of gift-giving has taken on a number of shapes in today's society. Devina Singhania, the Founder of 'LE JAHAAN', a local home and decor accessories company, explains how the gifting paradigm has shifted.

Q: What do consumers expect from the gifting business and packaging designers these days?

A: Today's consumers are expecting more minimal sustainable products, designs and mediums. They are now more conscious about how their purchase affects the environment. Considering this shift in consumer buying, it's extremely important for companies to increase their commitments to responsible business practices and design products that are meant to be reused or recycled.
