Mars in 30 days – Russian scientists are building a plasma engine that could slash travel time Long before any spacecraft can attempt a faster journey to Mars, scientists must first solve one of space exploration’s biggest challenges: propulsion. Chemical rockets, used to launch spacecraft into space from Earth, burn fuel quickly and produce a…

For hundreds of years, night didn’t mean a long sleep. Long before electric lights lit up homes and streets, people lived their lives according to the natural rise and fall of daylight. People changed their routines when the Sun went down and darkness came quickly. Historical records indicate that in various regions of Europe, Africa,…

Psychrobacter SC65A.3 is a 5,000-year-old cold-adapted bacterium resistant to multiple modern antibiotics/ AI Illustration A team of Romanian researchers has identified a bacterium preserved for roughly 5,000 years inside an underground ice deposit that can already withstand multiple modern antibiotics. The organism, recovered from Scărișoara Ice Cave in north-west Romania, survived frozen conditions for millennia…

Across large parts of rural Australia, farmers are facing harsher conditions. Rainfall is less reliable. Soils are losing structure. Fields that once supported crops are increasingly turning to dust. Years of drought and intensive farming have stripped soil of organic matter, making it harder for land to absorb and retain water. For many growers, the…

The Helix nebula, imaged here, lies 650 light-years away in the constellation Aquarius. Also known as NGC 7293, it is a typical example of planetary nebulae. (Image credit: Nasa) As children, many of us remember lying on terraces or open fields, trying to count stars. One, two, three and then losing track. Your parents would…

The waters of Lake Victoria have turned an unsettling green. And it seems, it’s not just a passing bloom this time. Local fishermen barely flinch anymore. What was once occasional now appears almost permanent. The world’s largest tropical lake is changing, and people who rely on it are feeling the effects every day. Millions in…

Source: University of Florida Gravity seems constant but it turns out, Earth is weirder than that. Gravity actually wobbles a bit across the planet. And the weakest spot isn’t the oceans or the mountains but right under Antarctica. Scientists now say this part of the frozen continent sits above Earth’s strongest “gravity hole.” And it…

What is the difference between asteroids, comets, and meteors Space around the Sun contains far more than planets. Scattered through it are smaller bodies made of rock, metal, ice and dust. These objects move on their own paths, sometimes quietly beyond Jupiter, sometimes crossing close to Earth. The terms ‘asteroid’, ‘comet’ and ‘meteor’ are often…

Scientists warn! Gulf Stream collapse could trigger severe global disruption Scientists are again examining the strength of the Atlantic Meridional Overturning Circulation, the vast ocean system that moves warm water northwards through the Atlantic. The current, often linked in public discussion to the Gulf Stream, helps shape weather patterns across Europe, North America and parts…

4.4 billion-year-old mineral found in Australia reveals new clues about Earth’s formation (AI-generated) Old crystals found in Western Australia are drawing fresh attention from geologists studying how the planet first took shape. These minerals, known as zircons, were recovered from ancient rocks in the Jack Hills region and are dated to be more than four…
