This is just one of many military advancements the nation has made against its arch-rival.
Back in July, South Korea undertook a 33-minute flight of its homegrown KF-21 fighter jet for the first time flaunting its military might and perhaps sending a message to North Korea.
South Korea is pursuing stealth drones that could take out North Korean air defenses as part of a “manned-unmanned teaming system.”
This finding “proved” the significance of chromosomal rearrangement, a crucial evolutionary indicator of the emergence of a new species.
Researchers from the Chinese Academy of Sciences (CAS) claim to have found a novel technique for programmable chromosome fusion successfully producing mice with genetic changes “that occur on a million-year evolutionary scale” in the laboratory.
The findings could shed light on how chromosome rearrangements—the tidy packages of organized genes provided in equal numbers by each parent, which align and trade or blend traits to produce offspring—influence evolution, reported Phys.org on Thursday.
Evolutionary chromosomal changes may take a million years in nature, but researchers are now reporting a novel technique enabling programmable chromosome fusion that has successfully produced mice with genetic changes that occur on a million-year evolutionary scale in the laboratory. The result may provide critical insights into how rearrangements of chromosomes—the tidy packages of organized genes, provided in equal number from each parent, which align and trade or blend traits to produce offspring—influence evolution.
The oldest radio galaxy yet discovered is hidden in a cluster.
Astronomers claim to have found the oldest fossil radio galaxy yet discovered, hiding in a cluster. The brightest galaxy in the cluster erupted as a result of supermassive black hole activity, blowing massive bubbles of radio light into space, according to a report published by ScienceAlert.
“These newly discovered bubbles — known as radio lobes, or a radio galaxy — are the oldest of their kind we’ve ever seen,” claimed the astronomers’ team led by Surajit Paul and Savitribai Phule from Pune University in India.
A second team of astronomers led by Gopal Krishna of the University of Mumbai also discovered a pair of younger lobes that are linked to the same parent galaxy.

Imagine two towns on two opposite sides of a mountain. People from these towns would probably have to travel all the way around the mountain to visit one another. But, if they wanted to get there faster, they could dig a tunnel straight through the mountain to create a shortcut. That’s the idea behind a wormhole.
A wormhole is like a tunnel between two distant points in our universe that cuts the travel time from one point to the other. Instead of traveling for many millions of years from one galaxy to another, under the right conditions, one could theoretically use a wormhole to cut the travel time down to hours or minutes.
You’ll often see wormholes in science fiction as a way to travel across the Galaxy.
Digital waste is a growing environmental and health problem whether dumped in landfills in the Global North or South. Are there solutions?
Meta CEO Mark Zuckerberg was a recent guest on The Joe Rogan Experience podcast, and during the episode, he discussed, among other things, neural technology. During his conversation, Zuckerberg remarked that Elon Musk’s Neuralink would probably not be popular in the next 10–15 years because “normal people” would not want to have devices implanted in their brains that are made of non-mature technology.
Zuckerberg admitted that Meta is researching neural interface tech as part of the company’s push into the metaverse, though he also noted that the tech company is focusing on innovations that can receive signals from the brain but does not send any information back to it.
In later comments, the Meta CEO noted that companies like Elon Musk’s Neuralink, which is developing a device that can be implanted into people’s skulls, is taking neural technology “super far-off.” Neuralink’s implant is designed to record and stimulate brain activity, which Musk has stated could help people address conditions such as obesity.
Modern satellites are becoming a collection of mass-produced computers floating in space. By the end of the decade, thousands more will be out there. But with the increasing reliance on orbital technology comes a growing appetite for hacking it.
Data relayed via satellites is not immune to hacking. James Pavur, an Oxford PhD focusing on satellite systems security, has proven the above statement to be disturbingly evident. With his team, he used $300 worth of satellite TV equipment to intercept vast amounts of information distributed along the larger part of the Northern hemisphere.
“When you’re eavesdropping on satellite internet signals, you’re effectively seeing what someone’s ISP would see. You see every website that a customer browses to, or every email that they receive for every account that they own,” Pavur told CyberNews.

We’re in the midst of a data revolution. The volume of digital data created within the next five years will total twice the amount produced so far — and unstructured data will define this new era of digital experiences.
Unstructured data — information that doesn’t follow conventional models or fit into structured database formats — represents more than 80% of all new enterprise data. To prepare for this shift, companies are finding innovative ways to manage, analyze and maximize the use of data in everything from business analytics to artificial intelligence (AI). But decision-makers are also running into an age-old problem: How do you maintain and improve the quality of massive, unwieldy datasets?
Imagine two towns on two opposite sides of a mountain. People from these towns would probably have to travel all the way around the mountain to visit one another. But, if they wanted to get there faster, they could dig a tunnel straight through the mountain to create a shortcut. That’s the idea behind a wormhole.

Instead of traveling for many millions of years from one galaxy to another, under the right conditions, one could theoretically use a wormhole to cut the travel time down to hours or minutes.
Because wormholes represent shortcuts through space-time, they could even act like time machines. You might emerge from one end of a wormhole at a time earlier than when you entered its other end.
Plants use light waves from only a portion of the spectrum for photosynthesis—the remainder can be recovered and used to generate solar power. That’s the idea behind the solar modules developed by EPFL startup Voltiris. Following encouraging preliminary results, a new pilot installation was recently installed in Graubünden.
In Switzerland, growing tomatoes, cucumbers, peppers and other light-and heat-intensive vegetables requires building a greenhouse—but operating one consumes a huge amount of power. Farmers have to carefully balance crop yields and economics with environmental concerns. “It costs more than CHF 1.5 million a year to heat a 5-hectare greenhouse,” says Nicolas Weber, the CEO of Voltiris. “And a greenhouse of that size emits roughly the same amount of CO2 per year as 2,000 people.”
The Swiss federation of fruit & vegetable growers, which cultivate several thousand hectares across the country, has set a target of eliminating all fossil-fuel-based energy from its farming processes by 2040. The system developed by Voltiris can go a long way towards reaching that goal. Its technology is based on the fact that plants don’t use all of the waves contained in sunlight; the remaining ones can be concentrated onto photovoltaic (PV) cells to generate solar power. Voltiris’ system is lightweight and designed to track the sun’s movement across the sky, and boasts daily yields on par with conventional solar panels. The first vegetables grown under Voltiris’ system were harvested this summer through pilot tests carried out at two greenhouses, in the cantons of Valais and Graubünden.
