NASA is planning to send small devices containing human cells in a 3D matrix — known as tissue chips or organs-on-chips — to the International Space Station (ISS) to test how they respond to stress, drugs and genetic changes.

Made of flexible plastic, tissue chips have ports and channels to provide nutrients and oxygen to the cells inside them.

The “Tissue Chips in Space” initiative seeks to better understand the role of microgravity on human health and disease and to translate that understanding to improved human health on Earth, NASA said.

“Spaceflight causes many significant changes in the human body,” said Liz Warren, Associate Program Scientist at the Center for the Advancement of Science in Space (CASIS) in the US.

“We expect tissue chips in space to behave much like an astronaut’s body, experiencing the same kind of rapid change,” Warren said.

The US space agency is planning the investigations in collaboration with CASIS and the National Center for Advancing Translational Sciences (NCATS) at the National Institutes for Health (NIH).

Many of the changes in the human body caused by microgravity resemble the onset and progression of diseases associated with ageing on Earth, such as bone and muscle loss. But the space-related changes occur much faster.

That means scientists may be able to use tissue chips in space to model changes that might take months or years to happen on Earth.

This first phase of Tissue Chips in Space includes five investigations. An investigation of immune system ageing is planned for launch on the SpaceX CRS-16 flight, scheduled for this year.

The other four, scheduled to launch on SpaceX CRS-17 or subsequent flights, include lung host defense, the blood-brain barrier, musculoskeletal disease and kidney function.

In addition, four more projects are scheduled for launch in summer 2020, including two on engineered heart tissue to understand cardiovascular health, one on muscle wasting and another on gut inflammation.

Also called a micro-physiological system, a tissue chip needs three main properties, according to Lucie Low, scientific programme manager at National Center for Advancing Translational Sciences in the US.

“It has to be 3D, because humans are 3D,” she explained.

“It must have multiple, different types of cells, because an organ is made up of all kinds of tissue types. And it must have microfluidic channels, because every single tissue in your body has vasculature to bring in blood and nutrients and to take away detritus,” she added. (IANS)

Apple has managed to reopen nearly 256 retail stores out of more than 500 worldwide, as it aims to safely restart operations.

Apple closed all its retail stores outside Greater China in March as COVID-19 pandemic spread. All the Apple stores in Greater China are now open.

“In China, and later around the world, we were one of the first companies to close our stores. In Greater China, we saw the importance of swift action — and the critical importance of social distance — to slow the virus’ spread,” according to Apple’s head of retail Deidre O’Brien.

“As time has gone on, we’ve continued to refine and expand our in-store health and safety measures, which have proven so effective in places like Greater China, where our stores have been safely open for months,” he added.

Apple is taking some additional steps in most places. Throughout the day, Apple is conducting enhanced deep cleanings that place special emphasis on all surfaces, display products, and highly trafficked areas.

“Face coverings will be required for all of our teams and customers, and we will provide them to customers who don’t bring their own. Temperature checks will be conducted at the door, and posted health questions will screen for those with symptoms — like cough or fever — or who have had recent exposure to someone infected with COVID-19,” O’Brien elaborated.

Oil Pulling: An Ayurvedic Treatment to Boost Immunity

Oil pulling is regarded as an ancient Ayurveda treatment that dates back to more than 3,000 years.

Considered as a detoxification therapy, it is done by taking a spoonful of cold pressed virgin oil (preferably coconut oil) and swishing it in your mouth for about 5 minutes, similar to using a mouthwash. The purpose of oil pulling is to swish the oil around in your mouth, between the teeth to get rid of bacteria in the mouth, spit it out and immediately rinse with some warm water.

Nutritionist Sheryl Salis shares how oil pulling that can help improve your immunity, uses of virgin coconut oil and the method of oil pulling:

Oil pulling is an alternative health practice gaining traction in recent times not only for oral health but also as an immunity boosting measure. As the mouth is a home to millions of microbes including bacteria, the oil pulling process helps get rid of these bacteria through swishing oil in the mouth and in-between the teeth. Swishing the oil for a prolonged period cleanses the mouth and decreases the bacterial load. Not only does this promote oral hygiene, this technique aids in overall health and well-being.

With the COVID-19 pandemic spread across the globe, it is recommended to build and maintain a strong immune system to help combat the risk of being infected. While external precautionary measures like sanitizing and washing hands are essential, maintaining basic hygiene measures and eating healthy to build one’s immunity is of utmost importance.

Using virgin coconut oil to build immunity

Cold pressed virgin coconut oil is a superfood recommended for its myriad health benefits; it is a rich source of naturally occurring Lauric acid and contains Vitamin E which helps to improve body’s immunity. The medium Chain Fatty Acids (MCFAs) that contain lauric acid and caprylic acid strengthens the immune system and has anti-viral properties. Therefore, Adding 2 spoons of virgin coconut oil to the diet every day can help improve the immunity and maintain a healthy, holistic lifestyle.

In most Indian household’s, virgin coconut oil is a staple for consumption and beauty practices and is slowly making its way in the mainstream wellness community for oil pulling. Known for its immune boosting properties, virgin coconut oil can be introduced as an effective technique into your heath regime.

eTake about 1 tablespoon of virgin coconut oil in the mouth and swish it for about 3-5 minutes.

eDiscard the oil by spitting it out. Do not swallow the oil as you will ingest the toxins with it as well

eRinse the mouth with warm water and brush your teeth as usual

eRepeat the process 3-4 times a week. (IANS)
