The Indian Space Research Organisation (ISRO) on 14 July 2021 successfully conducted the third long-duration hot test of the liquid propellant Vikas engine for the Gaganyaan programme, the country’s first manned mission to space.

According to the Satish Dhawan Space Centre (SDSC) website, the GSLV launch is scheduled for August and PSLV is scheduled for September. However, the dates have not been specified as yet.

The automated system consists of three simple steps–the septic tank (which is placed under the track, i.e., train line) top cover gets opened when train approaches to the septic tank place by using Radio Frequency Identification (RFID) sensor and reader placed at Engine and septic tank position respectively, sewerage material in toilet tanks is dropped into the septic tank when they are mutually synchronized, and finally the septic tank cover gets closed when train departs away from it.

In a recent study, scientists from S. N. Bose National Centre for Basic Sciences, an Autonomous Research Institute established under the Department of Science and Technology, Govt. of India, have theoretically shown that there is an optimum size of the receptor clusters at which the E.coli cell shows the best-directed motion guided by chemical signal received from its environment.

In a new study, scientists at the Indian Institute of Science (IISc) have experimentally shown the existence of two species of few electron bubbles (FEBs) in superfluid helium for the first time. These FEBs can serve as a useful model to study how the energy states of electrons and interactions between them in a material influence its properties.

A study by a team of researchers at the Government of India’s Department of Biotechnology’s Manesar-based National Brain Research Centre (NBRC) has helped gain new insights into molecular mechanisms involved in the proliferation of cancer cells, which may aid in the treatment of cancers based on the body clock.

In the new study, researchers have designed one using thermoplastic polyurethanes (TPU) and Polyethylene terephthalate (PET) as tribo layers. The easy availability of the active material and the simplicity of the fabrication process make it cost-effective over currently available fabrication techniques. The resulting device has also been found to be highly efficient, robust, and gives reproducible output over long hours of operation.
