‘Maglev’ is a portmanteau of ‘magnetic levitation’. Instead of running on wheels, maglev technology uses strong magnetic fields to lift the train and move it forward. Since the train floats above the track, there is no rolling friction during normal operations, nor are operations affected by inclement weather, like rain or snow. The result: the...

First ‘exomoon’ found comes with a challenge Using the radial velocity method, astronomers have found a large body orbiting a brown dwarf, CD-35 2722 B, which orbits a star. It is estimated to be 90% as massive as Jupiter and orbiting the brown dwarf every 170 days on an oval path. The find is a...
India’s green transition is missing long-duration energy storage
On May 21, India recorded its highest peak demand of 270.8 gigawatt (GW) during the day, an increase of approximately 90 GW from the same window in 2019. While power generators often meet India’s summer peak, the demand again increases at night, especially due to the use of air conditioners. This underscores the need for...
Space Exploration Day| Meet the parts that make space exploration possible
Launch Vehicle A launch vehicle, commonly known as a rocket, is the powerful vehicle that carries a spacecraft from Earth into space. Its primary job is to generate enough thrust to overcome Earth’s gravity and place the mission on the correct path. Once it has completed this task, the rocket’s role ends. What does it...
Space Exploration Day | Life at the International Space Station
In low Earth orbit can be found the International Space Station — a large laboratory where astronauts from different countries live and work together while circling Earth every 90 minutes. What began as a project involving the United States, Russia, Europe, Japan, and Canada is today a strong symbol of cooperation among countries for the...
As BSF mulls 90-km Sundarbans fence, security clashes with ecology
Just a few months after the Border Security Force (BSF) explored the curious prospect of releasing snakes and crocodiles into rivers at the Indo-Bangladesh border to deter “illegal activities,” the security force has now initiated another controversial feasibility study for a colossal project to safeguard the area. This time, as The Hindu reported, it is...
Space Exploration Day | How are astronauts trained?
By way of our sharp fascination towards a spaceflight event when it happens, we tend to forget reading into the entire process that led to that moment. Process, in today’s ‘all-instant’ era, seems to lose value unless you are part of it. Going to space in a rocket and coming back sounds simply doable but...
How did we identify fossil fuels to be remains of fossils, particularly those of dinosaurs?
— Vivek Keshri, Patna A: Scientists identified fossil fuels to be the remains of ancient life using physical and chemical evidence. Early on, some scientists thought oil was a mineral ‘sweated’ out of the earth’s interior. But in the 16th century, naturalists found imprints of leaves and tree trunks inside coal seams, suggesting that coal...
India’s rice fields now rank among world’s top methane hotspots
Greenhouse gas (GHG) emissions from paddy fields worldwide have doubled since the 1960s, a new study in NatureFood has found. In the most recent decade, 2011-2020, paddy fields around the world produced around 1.1 billion tonnes of carbon dioxide-equivalent (CO2-e) emissions every year — a 90.4% increase from the annual emissions between 1961 and 1980,...
‘Cruel, wasteful’: Dakar port a hotspot for illegal shark fins
In the high seas off west Africa, a fisherman on a Chinese longline tuna vessel cuts the fins off a live shark before throwing it back in the water to suffocate and drown. Its lucrative appendages will be landed at the port of Dakar before being shipped onward to Asia for use in shark fin...
