Video: BSF, Meghalaya Cops Pursue, Arrest Armed Bangladeshi Gang

Four Bangladeshi nationals who allegedly attacked an Indian villager at a border area in Meghalaya have been arrested by the Border Security Force (BSF). Visuals of the aftermath of the operation to capture the four Bangladeshi suspects show the BSF questioning them in a forest. The police said the "brazen attack" on the villager happened at night on Friday. Balsrang A Marak, who runs a shop near the border with Bangladesh, was sleeping when eight-nine armed men entered his shop and kidnapped him, the police said. Mr Marak alleged the "Bangladeshi gang" handcuffed him and marched him toward the border. He said he was sure they would have slit his throat. As they were walking in the dark, he managed to sprint away and run inside the first house he could find in the area. The gang fired shots toward him, the shopkeeper said. The BSF along with the police immediately launched an operation and captured three Bangladeshi suspects. The police fired two warning ro...

US Scientists Demonstrate Method To Deflect Asteroids Using Nuclear Blast

Asteroid collisions with Earth are surprisingly common, with NASA estimating 48.5 tonnes of meteoric material entering our atmosphere daily. Most burn up, producing shooting stars. Although devastating asteroid impacts are rare in Earth's history, humanity has learned a crucial lesson from the catastrophic event 66 million years ago. The asteroid responsible for the dinosaurs' extinction was approximately six miles wide, but significantly smaller objects still pose a significant threat. In the face of potentially catastrophic asteroid impacts, scientists are racing to develop innovative solutions to protect our planet. 

In New Mexico, scientists are exploring a futuristic solution to defend Earth against asteroid threats: harnessing X-ray blasts from nuclear explosions, the Guardian reported. Scientists at Sandia National Laboratories in Albuquerque have successfully demonstrated a revolutionary method to deflect incoming asteroids using nuclear explosions. For the experiment, researchers harnessed the power of X-rays from a nuclear blast to vaporise the surface of a nearby asteroid.

The process works by unleashing an immense pulse of radiation, heating the asteroid's surface to tens of thousands of degrees. This creates a rapidly expanding ball of gas that can nudge the asteroid off its catastrophic course. By precisely calculating the blast's impact, scientists believe this technique can effectively push threatening asteroids away from Earth, potentially saving humanity from doomsday. 

"The primary mechanism involves using X-rays to rapidly heat the target surface, causing it to vaporize and expand into the adjacent vacuum. The expanding gas pushes against the asteroid, transferring momentum (in the opposite direction)," authors of the study published Monday in the journal Nature Physics wrote. 

Scientists noted that the nuclear option is for larger asteroids, particularly when time is short. Researchers believe this strategy can effectively deflect asteroids up to 2.5 miles wide, although this isn't a rigid limit.

“If there is enough warning time, one can certainly deflect larger asteroids,”  Dr Nathan Moore, the first author of the study said. 

Mr Moore and his team plan to conduct further experimental tests to refine the X-ray deflection technique, building on their initial success. Their goal is to enhance the method's effectiveness through additional laboratory experiments. Ultimately, they envision a space-based demonstration, similar to NASA's DART (Double Asteroid Redirection Test) mission, to test the technique on a real asteroid.

US Teen Who Slapped Teacher In Classroom Faces Kidnapping, Assault Charges

A US high school student, who attacked two teachers in school premises, has been hit indicted on assault and kidnapping charges, according to a report in Fox News. The outlet said that the attacks took place at Parkland High School in Winston-Salem, North Carolina. A video of 17-year-old Aquavis Hickman hitting one of the teachers in the classroom in April had gone viral on social media, leading to a barrage of comments. Hickman is being tried as an adult and his case has been moved from a juvenile court to a superior court. Watch the video: NEW: North Carolina high school student who went viral for hitting his teacher has been smacked with felony charges & is being charged as an adult.

US Reopens Lake Michigan Airspace After Closure Over "National Defense"

US officials restricted the airspace over Lake Michigan on Sunday citing a potential new threat to national security but soon reopened the skies, as the United States and Canada respond to multiple air intrusions. The Federal Aviation Administration (FAA) announced "temporary flight restrictions" over one of the Great Lakes along the US-Canada border, designating it as "national defense airspace," one day after a similar closure over Montana led to the scrambling of US fighter jets. The Montana closure was ordered over a "radar anomaly," but no object was discovered. Similarly, the Lake Michigan restrictions were lifted shortly after they were announced, apparently with no threat detected. "The FAA briefly closed some airspace over Lake Michigan to support Department of Defense activities. The airspace has been reopened," the agency said in a statement to AFP. Sunday's action over Lake Michigan marked the latest move to address a series ...

Biden Orders US Military To Shoot Down Iranian Missiles Targeting Israel

President Joe Biden has ordered the US military to "aid Israel's defense" and shoot down any and all Iranian missiles targeting Israel, the White House said. President Biden and Vice President Kamala Harris, the Democratic nominee in next month's US presidential election, are both monitoring Iran's attack on Israel from the White House situation room, it said. "President Biden directed the US military to aid Israel's defense against Iranian attacks and shoot down missiles that are targeting Israel," the White House said in a statement. A call that Joe Biden had scheduled with rabbis today ahead of the Jewish high holiday season - which begins later this week with Rosh Hashanah, the Jewish new year - had been postponed to another day, a White House official said. The United States and other western allies also stepped in to help defend Israel against a combined Iranian missile and drone attack in April, which Tehran launched in retaliation for an ...
