Apple’s iPhone 14 offers camera upgrades, satellite feature

Apple Inc. unveiled a new lineup of devices Wednesday with few surprises beyond one major one: It didn’t raise its US prices during one of the worst years for inflation in decades. At its biggest product-launch event of the year, dubbed Far Out, the company introduced the iPhone 14, fresh AirPods Pro earbuds and an Apple Watch upgrade that included a first-ever Ultra model. The iPhone retains the general look of the older version while getting camera enhancements, a long-anticipated satellite-messaging feature and -- on the higher-end models -- a new interface called the Dynamic Island. Apple is betting the…

China's new sky train levitates on a magnetic track 33 feet in the air

China is well known for its futuristic maglev trains, which use electromagnets to propel the vehicles over tracks at high speeds. Now the country has unveiled its first suspended maglev line built with permanent magnets, which engineers claim can keep a 'sky train' afloat even without a power supply. The 2,600ft experimental track, known as the Red Rail, is located in Xingguo county, Jiangxi province, in southern China. It uses powerful magnets to produce a constantly repelling force strong enough to lift a train with 88 passengers into the air, according to a report in the South China Morning Post.…

Thinking of living up to 200 years? Scientists are working on a drug to help you achieve that longevity

Adding another 100 years to your lifespan might be the stuff of science fiction but scientists are working on a miracle drug that would make it a reality. The drug, taken in pill form, works by eliminating cells that contribute to the ageing process in the human body, thus potentially doubling our lifespan. Human ageing is hurried along by cells called ‘zombie cells’, scientifically known as senescent cells. These cells stop dividing over our lifespan, accumulate inside our bodies, and eventually release compounds that speed up ageing. The drug has been tested on mice in a 2020 trial and the…

The big myth about charging tech you should stop believing

The average consumer will replace a smartphone 2.6 years after buying it (via Statista). If you have a laptop, you can expect it to last at least 4 to 7 years before you need an upgrade, according to Tech Guided. However, the lifespan of your smartphone, laptop, and even your electric vehicle depends on the battery's health. In fact, fewer people tend to upgrade their smartphones if they have an option to replace the battery -- Apple found this out after a loss in its revenue. Of course, batteries are not meant to last forever but you can make them…

WhatsApp extends time limit to delete a message, boosts privacy features

WhatsApp now allows you to delete a message for up to two days and 12 hours (60 hours in total), so you can remove an accidentally sent chat even after hours. Previously, this limit was 1 hour, 8 minutes and 16 seconds — yep, there were seconds involved. The company’s tweet about this feature just mentioned “little over two days” but didn’t specify the 12-hour part. WhatsApp first introduced the unsend feature back in 2017 with a time limit of just seven minutes but later increased it to one hour and eight minutes. Last year, WABetaInfo noted that the company…

How the Hellfire missiles used to kill al-Qaeda leader al-Zawahiri work

Photos showing the home in the heart of Kabul where al-Qaeda leader Ayman al-Zawahiri was killed in a CIA drone strike earlier this week show very little structural damage and U.S. officials say no one else was injured. To make that happen it appears that planners decided to use modified versions of the Hellfire missiles that are the main weapons carried by MQ-9 Reaper drones. Used in other counterterrorism drone strikes, the R9X missile is a version of the Hellfire missile that has an inert warhead and whose main feature is the deployment of metal blades that kill targets with…

After chess robot breaks boy's finger, it's clear the machines are coming for us

I take no joy in saying this, but for our own survival, we humans must immediately destroy all robots. They drew first blood. In case you missed the news story – perhaps because you were kidnapped by a self-driving robot car – a chess-playing robot at a tournament in Russia grabbed and broke a 7-year-old boy’s finger during a game last week. Video of what I’m calling “the attack” shows a robotic arm lifting a chess piece off the board, followed by the boy quickly sliding a different piece across the board. As the human child is moving the piece,…

Why it's so hard to defend against cruise missiles

On July 14, the Center for Strategic and International Studies in Washington, DC held a one-day conference premised on a specific threat: What if, in the future, war comes to the United States via cruise missile? Pointing to new developments in cruise missile technology, and the limitations of existing early warning systems that are focused on the high arcing trajectories of ballistic missiles, the CSIS conference and accompanying report suggests that to defend the continental United States from such a threat, the military should adapt and deploy the kind of cruise missile defenses presently used as regional weapons. Unlike ballistic…

'Ghost heart': Built from the scaffolding of a pig and the patient's cells, this cardiac breakthrough may soon be ready for transplant into humans

The first time molecular biologist Doris Taylor saw heart stem cells beat in unison in a petri dish, she was spellbound. “It actually changed my life,” said Taylor, who directed regenerative medicine research at Texas Heart Institute in Houston until 2020. “I said to myself, ‘Oh my gosh, that’s life.’ I wanted to figure out the how and why, and re-create that to save lives.” That goal has become reality. On Wednesday at the Life Itself conference, a health and wellness event presented in partnership with CNN, Taylor showed the audience the scaffolding of a pig’s heart infused with human…
