Tamil Nadu, Mar 11, 2017: At the site of the 4-day Bokkapuram Temple festival organised by the Sholur panchayat in the periphery of Mudumalai Tiger Reserve (MTR), the garbage littered by the devotees and the shops is still uncleared as reported by The Hindu.
The wildlife of the area has been affected as well, elephants were seen roaming around near the temple, consuming the plastic bags and food waste according to one local.
About 150 kg of plastic waste is generated every year during this 4-day festival and about one tonne waste is cleaned every year, according to M. Kumaravelu, field officer of CPR Environmental Education Center, who used to organize clean-ups after the completion of the temple festival every year, with the help of volunteers. But as the district administration does not offer them any help, they had to stop.

An official from the Sholur panchayat had assured that the clean up would start by Monday, and that the delay has been caused due to the unavailability of workers to carry out the clean up process.
Nagina Reddy a resident of Bokkapuram who runs a resort, thinks that the panchayat should help them out with trucks that would collect the waste and take it to a waste processing unit.
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)
