World's First 3D-printed Steel Bridge Opens in Amsterdam
World's first 3D-printed steel bridge was opened to the public in Amsterdam earlier this month. It was developed by MX3D, a Dutch robotics company, in collaboration with a consortium of experts, and represents a major milestone for 3D-printing technology. After four years in development, the bridge was unveiled by Her Majesty Queen Máxima of the Netherlands. It was installed over one of the oldest canals in Amsterdam's city centre – the Oudezijds Achterburgwal.
The 12-metre-long steel structure will be a 'living laboratory' that would capture and transmit data on its health in real-time to show how it changes over its lifespan. The smart sensor network was designed and installed by a team from The Alan Turing Institute.
China Gearing Up to Activate the World's first 'Clean' Commercial Nuclear Reactor
Chinese government scientists have unveiled plans for a first-of-its-kind, experimental nuclear reactor that does not need water for cooling.
The molten-salt nuclear reactor, which runs on liquid thorium rather than uranium, is expected to be safer than traditional reactors because the molten salt cools and solidifies quickly when exposed to the air, insulating the thorium, so that any potential leak would spill much less radiation into the surrounding environment compared with leaks from traditional reactors.
The prototype reactor is expected to be completed next month, with the first tests beginning as early as September. This will pave the way for the building of the first commercial reactor, slated for construction by 2030.

Scientists Map the Mysterious Interior of Mars for the First Time Ever
Like a bruised peach sliced apart to reveal an enormous yellow pit, Mars shares its inner mysteries in the first-ever map of an alien planet's interior — released as part of three new studies published July 22 in the journal Science.
This premiere look at the Martian interior is the culmination of two years of research (and decades of planning) with NASA's InSight lander — a stationary science robot deployed to Mars in 2018 with the sole mission of studying the Red Planet's unseen innards. About a month after landing on the flat, smooth plain known as Elysium Planitia, InSight used its robotic arm to install a tiny seismometer on the nearby Martian surface, and began listening for marsquakes — seismic vibrations within the planet, similar to earthquakes on Earth.
According to NASA researchers, unlike Earth, Mars has no tectonic plates; its crust is instead like one giant plate. But faults, or rock fractures, still form in the Martian crust due to stresses caused by the slight shrinking of the planet as it continues to cool.

NEA Scout: NASA's New Spacecraft
NASA has announced that its new spacecraft, NEA Scout, has successfully undergone all the required tests and has now been safely tucked inside the Space Launch System (SLS) rocket.
NEA Scout is among one of several payloads that will hitch a ride on Artemis I, which is expected to be launched in November. Near-Earth Asteroid Scout (NEA Scout) is a small spacecraft which is not bigger than a big shoebox. NEA Scout's primary mission is to collect data from a near-Earth asteroid. This will be America's first interplanetary mission that will be using special solar sail propulsion. This spacecraft has been made using stainless steel alloy booms and will deploy an aluminium-coated sail which is of 925 square feet. This spacecraft will take around two years to reach the targeted asteroid and will nearly 93 million miles away from the Earth during its encounter with the asteroid.
The spacecraft is equipped with high-grade scientific special cameras that can take pictures from ranges of 10 cm/pixels to 50 cm/pixels. Post taking the images it can also process them and reduce their file sizes before using its medium-gain antenna to send them to the earth-based Deep Space Network.

Russia is Launching a New Module for the International Space Station
Russia is launching a new module for the International Space Station (ISS), after more than a decade of delays. The Nauka module is set to lift off from Baikonur Cosmodrome in Kazakhstan on top of a Proton-M rocket, along with a new robotic arm for the station created by the European Space Agency.
The ISS is composed of modules and equipment from different space agencies including Europe, Japan and Canada, but the bulk of the station is composed of two main sections, a Russian segment and a US segment. At 13 metres long and weighing more than 20 tonnes, Nauka, also called the Multipurpose Laboratory Module, will be among the largest in Russia's half.
Researchers at the Indian Institute of Technology (IIT), Ropar have developed a first-of-its-kind device that can regulate the flow of medical oxygen from cylinder during inhalation and exhalation by a patient, thereby reducing wastage. The device supplies a required volume of oxygen to a patient during inhalation and trips when the patient exhales, thereby saving the flow of oxygen at that time.
AMLEX is a system developed specifically for oxygen cylinders. It synchronises the flow of oxygen with inhalation and exhalation of a patient. This conserves a large amount of oxygen in the reservoir.
The device can operate on both portable power supply (battery) as well as line supply 220V-50Hz.
The device can be easily connected between the oxygen supply line and the mask worn by a patient. It uses a sensor which senses and successfully detects inhalation and exhalation of the user in any environmental condition.
Maharashtra to Issue Certificates Using Blockchain TechnologyMaharashtra to Issue Certificates Us...
Maharashtra will be the first state in the country to issue educational documents using blockchain technology. Forgery of documents is a serious concern for various educational and other institutions. Many steps are being taken to avoid forgery along with verification of documents. Maharashtra State Board of Skill Development has decided to issue blockchain-based certificates to students.
Around 10 lakh digital certificates will be issued to diploma holders of eight educational years. Mr. Malik said that Singapore, Malta and Bahrain are the only countries using this technology. Maharashtra will be the 1st Indian state and the world's largest user of Blockchain for educational certificates.
Each student will receive a "certficate_LegitDoc.zip" digital file containing the original PDF diploma certificate and its corresponding blockchain proof file. It can be verified within 10 seconds from anywhere around the world and does not require human intervention.
