How often should I replace the water filter in my refrigerator?
It’s generally recommended to replace your refrigerator’s water filter every six months to ensure clean and fresh-tasting water. However, this frequency might vary based on usage and water quality. Signs that it’s time to replace the filter include a decrease in water flow, off-tasting or discolored water, and the filter’s indicator light turning on.
What are some effective ways to reduce my refrigerator’s energy consumption?
To enhance energy efficiency in refrigerators, set the temperature to the optimal level to prevent excessive power consumption. Regular maintenance, such as cleaning the coils, helps improve performance and reduces energy use. Additionally, minimise the frequency of opening the door, as cold air escapes each time, making the appliance work harder to restore the temperature. These simple habits can significantly lower electricity consumption over time.
Factors to consider when buying an energy-efficient refrigerator
- Energy rating: Always choose a 5-star-rated refrigerator for maximum electricity savings and efficiency.
- Inverter technology: Opt for a digital inverter compressor as it adjusts cooling based on usage, reducing energy consumption.
- Size and capacity: Select a refrigerator that fits your household needs—larger models consume more power.
- Cooling technology: Look for features like Twin Cooling, Turbo Cooling, and Moist Balance Crisper for efficient cooling.
- Stabilizer-free operation: A built-in stabilizer protects the refrigerator from voltage fluctuations, ensuring durability.

Mysterious ‘zombie star’ speeds through the Milky Way at 177,000 km/h, capable of ripping human atoms; origin remains unknown | – The Times of India
In a stunning cosmological find, astronomers saw an ultra-massive and magnetic stellar remnant speeding through our galaxy at record speed. Called a “zombie star,” the object—properly known as SGR 0501+4516—is moving through the Milky Way at over 110,000 miles per hour (177,000 km/h). Even more dramatic is the star’s fatal magnetic field capable of ripping human matter apart atom by atom.
But aside from its velocity and brutality, the origin of this star is confounding astronomers and could redefine existing theories of how such objects are formed.
A ‘zombie star’ SGR 0501+4516 moving through Milky Way
SGR 0501+4516 is a magnetar—a neutron star with an unusual and extreme magnetic field. Neutron stars in general are dense remnants of giant stars that exploded as supernovae. Though tiny, a little larger than a city, neutron stars contain more mass than our Sun and are among the densest objects known in the universe, except for black holes.
Magnetars, though, take it a step further. With magnetic fields as much as 100 trillion times more powerful than Earth’s, they are the most magnetic objects in the universe. Only about 30 of these objects have been found in our galaxy.
SGR 0501+4516 was discovered in 2008, about 15,000 light-years from Earth. But a new study published April 15 in the journal Astronomy & Astrophysics has found something surprising: it’s not only strong—it’s also speeding through space at a surprisingly high speed.
Magnetic field strength of the ‘zombie star’
The magnetic field strength of SGR 0501+4516 is unimaginable. If it were to fly by at half the distance to the Moon, its magnetism would wipe out all credit cards on the planet. Get within 600 miles, and its magnetic force would dissolve the human body on an atomic level. Fortunately, the magnetar is no threat to our solar system and will stay safely far away.
By employing data from the European Space Agency’s Gaia spacecraft as well as the Hubble Space Telescope, scientists tracked the magnetar’s recent history and discovered a great enigma. At first assumed to have been born of the local supernova remnant HB9, SGR 0501+4516 was travelling much too quickly—and in the opposite direction—to have been born out of that place.
Indeed, when researchers mapped its galactic trajectory over the course of millennia, they found it doesn’t seem to be associated with any supernova remnants or giant star clusters. That’s a fly in the ointment of the conventional view of magnetar formation.
Zombie star hints at rare cosmic transformation
This surprising path has brought astronomers to a new theory: SGR 0501+4516 could have developed without a supernova explosion whatsoever. Rather, it could have resulted from the direct collapse of a white dwarf—the dense core that remains after a medium-sized star exhausts its fuel.
Usually, a white dwarf would explode as a supernova if nuclear reactions are triggered within it. But in exceptional conditions, theorists have suggested, it could instead collapse directly into a neutron star without going through the explosive stage.
“We think that this magnetar might have been formed through this exotic pathway,” said Andrew Levan, study co-author and astronomer at Radboud University and the University of Warwick.
Zombie star theory could unlock cosmic mysteries
This uncommon formation mechanism may have wider cosmic implications. If white dwarf collapse can actually produce magnetars, it may shed light on the enigmatic fast radio bursts (FRBs)—brief, brilliant pulses of radio waves—from distant galaxies that are too old to contain star deaths.
The group stresses that additional observational information is required to verify this theory. But the research raises new questions regarding magnetar formation and their contribution toward creating some of the universe’s most powerful and fleeting phenomena. “Figuring out where magnetars are born is one of the greatest challenges of high-energy astrophysics,” said study co-author Nanda Rea, an astrophysicist at Spain’s Institute of Space Sciences in Barcelona. “It might help us understand some of the most violent events in the universe.”

The Justice Department and a group of US states have argued that Google should be forced to sell off its popular Chrome browser.
Internet company Yahoo Inc. — backed by owner Apollo Global Management Inc. — would bid for the Chrome web browser if a federal court orders Google to divest it as a remedy for maintaining an illegal monopoly, a senior executive said.
Brian Provost, the general manager for Yahoo Search, testified Thursday during Google’s trial in Washington that his company estimates the browser would have a sale price in the tens of billions of dollars.
Chrome is “arguably the most important strategic player on the web,” Provost said. “We would be able to pursue it with Apollo.”
Provost testified as part of a three-week hearing in the Justice Department’s case against Alphabet Inc.’s Google to determine how to remedy the company’s monopoly in internet search. Judge Amit Mehta ruled last year Google illegally monopolized the market and is contemplating a package of changes proposed by antitrust enforcers.

The Justice Department and a group of US states have argued that Google should be forced to sell off its popular Chrome browser.
Yahoo was the leading search engine in the early 2000s before losing that position to Google. The company has changed hands several times; Apollo purchased it in 2021 from Verizon Communications Inc.
Since the Apollo takeover, Yahoo has been seeking to “revitalize” its search engine, and started building its own browser that remains in development, Provost said. The company has also considered buying a browser and became interested in purchasing Chrome as soon as the Justice Department’s proposal became public, he said.
Yahoo would likely have competition. OpenAI also would be interested in buying Chrome browser, the head of ChatGPT said during the trial Tuesday.
“Yes, we would, as would many other parties,” Nick Turley, OpenAI’s ChatGPT chief, said in response to a question about whether the company would seek to buy Google’s browser.
