Scientists create millirobot with simple design which can execute multi-locomotion
A group of scientists from Switzerland has created an insect-scale origami robot which can execute multi-locomotion. It's design was inspired by trap-jaw ants which have remarkable multi-locomotion mechanisms to jump upwards when threatened, by a sudden snapping of their mandibles.
New images of Chandrayaan-2 released a few days ahead of it's launch
ISRO has released new images of chandrayaan-2 mission which includes the first ever image of chandrayaan-2 satellite. The satellite satellite weighs about 3.8 tons. The mission will also carry a 27 Kg rover to the moon which will explore the lunar south pole. This six wheeled rover named 'Pragyaan' is equipped with cameras and other instruments to analyse the soil. This mission would cost only 1000 Cr Indian rupees. The launch date is 15th July 2019.
In a breakthrough, scientists demonstrate untethered flight of an insect-sized microscale aerial vehicle
A team of scientists from John A Paulson School of Engineering and Applied Sciences and Wyss institute for biologically inspired engineering, Harvard University, Cambridge, MA, USA have developed an extremely small insect-sized flapping-wing microscale aerial vehicle, which can fly without being tethered to external network. It consumes only about 110-120 mW power which is much lower than the other heavier than air flights.
New solar still can produces a record amount of fresh water and help millions.

Solar stills are devices which use the sun to evaporate dirty or salty water and condense the vapor into safe drinking water. Thus far, a large and expensive solar still could only produce a few liters of water daily. This is about to change now as researchers have developed a new material that accelerates the process of evaporation, enabling a small solar still to provide all the drinking water one family needs. If the technology comes at a cheap fortune to the market, it could provide millions of impoverished people access to clean drinking water. This new technology is developed by scientists at the University of Texas in Austin in the form of a new hydrogel. Any solar still which is using this hydrogel can distill water at a rate of 3.6 L/h/m2, the highest rate ever reported.
SPACEX launches Falcon heavy weight rockets with 24 payloads
SPACEX has finally launched its much delayed Falcon heavy from NASA’s Kennedy Space Center in Florida. The launch took place at 12.00pm IST. The rocket carries 24 payloads which will be launched at three different orbits and the rocket will undergo four separate upper stage engine burns.
New light weight device to make heart monitoring easier
A newly developed graphene based wearable device is can make heart monitoring easier and more efficient compared to the existing electrocardiograph machines. This new device is lightweight and stretchable due to which it can be placed over the heart for extended periods without discomfort. This work is reported in the Journal of Advanced Science.

NASA engineers at the Jet Propulsion Laboratory have attached a remote sensing mast to the mars rover which is about to be launched in 2020. During the interplanetary cruise, and its descent toward the Martian surface, the mast will be safely placed on the rover's deck. After the landing mast be raised to provide a high perch for the SuperCam, Mastcam-Z and Mars Environmental Dynamics Analyzer instruments and four Navcam engineering cameras. The mars rover 2020 which has the ability to accurately retarget its point of touchdown during the landing sequence is expected to land at Jezero Crater on Feb. 18, 2021.
India's ISRO to launch its own space station by 2030
Indian space research organization chief (ISRO) K Sivan said today that india would launch its first space station by 2030. The space station will mainly be conducting microgravity experiments. The space station is supposed to accommodate astronauts for about 20 days. However more details are not available about this mission for now. ISRO has currently plans to send humans to space and this mission is called 'Gaganyan'. The space station project will be an extension of this mission.
Researchers from the university of Colorado Boulder, have developed nanobio-hybrid organisms which can produce some biodegradable plastics and fuels such as gasoline, ammonia etc just by consuming carbon dioxide and nitrogen. For this microbial cells are injected with quantum dots which on photo-excitation would produce certain enzymes required to create the abovementioned products. Prashant Nagpal, lead author of the research and an assistant professor in CU Boulder's Department of Chemical and Biological Engineering. said "We're looking at a technique that could improve CO2 capture to combat climate change and one day even potentially replace carbon-intensive manufacturing for plastics and fuels."
Want to visit NASA’s International Space Station? Here is how you can

Apart from astronauts who happen to be scientists or military personnels, common men have always been denied the permission to visit outer space. Many people aspire to visit space in this life time of theirs. Much to their relief, NASA has announced that it will be starting space tourism to international space station (ISS) soon. The first flight to lSS is expected to take place sometime in 2020. The to and fro ticket alone is supposed to cost about 58 million USD. Extra charges will be there for food water and life support systems. The journey will be a month long.
Scientists have recently came-up with an AI based tool which can distinguish between 'normal' and 'abnormal' baby cries. A peculiar algorithm is used for this purpose.
According to Lichuan Liu, an associate professor at Northern illinois university, there are lots of health-related information in various cry sounds and the differences between sound signals infact carry the information,".
"These differences are represented by different features of the cry signals. To recognise and leverage the information, we have to extract the features and then obtain the information in it," said Liu.
"The ultimate goals are healthier babies and less pressure on parents and care givers," Liu concluded.
The work is published in IEEE/CAA Journal of Automatica Sinica (JAS)
Researchers from TUM develop permanent cooling system for quantum computers

Extremly low temperatures are mandatory for quantum operations. This is because qubits are more stable at low temperatures which is a compulsory requirement for the long life of a quantum computer. The research team from Technical University of Munich has come up with a new magnetic cooling system which is not only cheaper that the existing helium 3 based systems but also has a much longer life.
