A Tesla owner who complained on Twitter about their Model 3 burning to the ground in their driveway says Tesla will not respond to their demands for an explanation. According to a Tweet apparently made by a Tesla owner, at the time of posting (March 4), it had been 58 days since the burning-down incident occurred, and he had then yet to receive a response from Tesla’s customer service department about the cause of the fire. The owner also shared a video from his neighbour’s security camera from the night the vehicle inexplicably went up in flames. “I STILL believe Tesla makes great cars but their customer service is truly horrendous,” they wrote. While insurance should cover the cost of the vehicle, that’s not the point the owner is trying to make, they write. Instead, the problem here is that a brand-new vehicle caught fire without warning, without somebody driving it, while under warranty from the manufacturer, and the manufacturer’s apparently unwilling to address it.

Many swimming pools in Germany don’t have enough trained lifeguards—and in many places, this skilled labor shortage is leading to closures. The solution could be a floating underwater rescue robot. According to one German life-saving association, nearly 420 people drowned in Germany in 2019, with the majority losing their lives in fresh water lakes, but also in swimming pools. Now, a team of researchers from the Institute for Advanced Systems Technology of Fraunhofer Institute for Optronics, System Technologies, and Image Exploitation (IOSB) is aiming to improve the situation with an aquatic robot that uses AI, the only one of its kind worldwide. The scientists have used their years of expertise in the area of underwater robotics to develop the autonomous device that will assist lifeguards and rescue swimmers in emergencies.

According to adverse incident reports collected by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) 966 individuals have died after having received an mRNA vaccine for COVID-19. Between Dec. 14 and Feb. 19, 19,769 reports were made to the Vaccine Adverse Events Reporting System (VAERS) following immunizations with either the Moderna or Pfizer BioNTech mRNA vaccines (the only two vaccines given during the time period assessed). The 966 deaths represent 5 percent of the total number of adverse events reports. Of those who died, 86, (8.9 percent) died on the same day they got the shot. An additional 129, (13.4 percent) died within one day. An additional 97 died within 2 days, and 61 within 3 days.

In the volcanic region of East Africa’s Great Rift Valley, tectonic shifts are tearing the continent apart – and releasing unimaginable quantities of clean energy. Drive along the dusty dirt road that winds through Kenya’s Hell’s Gate National park, past the zebra, gazelles and giraffes, and you’ll see a plume of steam shooting skyward in the distance. Vehicles must sometimes swerve to avoid running over warthogs as they enter a vast valley dotted with dozens of steam vents – a factory of clouds. Blasts of steam billow loudly, releasing heat from deep within the Earth. But even more powerful is the steam you don’t see: that which twists through miles of tubes to push past turbines, generating a type of clean energy that won’t run out for millions of years. Atop this infernal labyrinth of tubes is Kenya’s Olkaria Geothermal Project, where a new addition to the powerplant is about to go online. At 86 megawatts, the Olkaria VI expansion will push the project’s total production to 791.5 megawatts.

There’s a growing debate whether it could help or hurt the environment Jaeson Cardiff often faces the question whether his industry is good for the environment or merely helping to delay the inevitable transition away from fossil fuels. Cardiff is the founder of CleanO2, which collects carbon fumes and exhaust from industrial buildings for use in soap and detergents. At his office in Calgary, he describes how interest in his business has grown exponentially by increased awareness about climate change and the dangers of greenhouse gas emissions. In the past two years, CleanO2 has grown from having one employee to 10, with operations expanding to the U.S. and Japan. Still, he finds himself at the forefront of the debate about natural gas, which is increasingly characterized as either a saviour or a villain in whether it helps or hurts the environment.

Medicevo’s Graphene Face Mask uses a patented production process that implants graphene into the fabric of the mask directly, creating a microscopic sharp-edged netting. When a virus comes in contact with Medicevo’s Graphene Face Mask, the graphene netting slices through the virus particle, killing it. The masks are scientifically proven to kill COVID-19 particles and other types of infectious diseases like the seasonal flu, which is key for disease control and prevention. Medicevo’s Graphene Face Mask features four layers of protection. The outer layer comprises high-quality antibacterial, non-woven fabric with strong air permeability but isolates droplets and large particles. The graphene layer and patented plating technology kill more than 99% of viruses and germs. A melt-blown cloth layer creates an isolation and dustproof effect, filtering particles less than 0.3 microns in size. Finally, a skin-friendly inner lining with honeycomb-woven fabric and adjustable ear loops stretch over the wearer’s nose and mouth to ensure a secure and airtight fit.

LOS ANGELES — NASA’s Mars rover Perseverance has taken its first, short drive on the surface of the red planet, two weeks after the robot science lab’s picture-perfect touchdown on the floor of a massive crater, mission managers said on Friday. The six-wheeled, car-sized astrobiology probe put a total of 6.5 metres (21.3 feet) on its odometer on Thursday during a half-hour test spin within Jezero Crater, site of an ancient, long-vanished lake bed and river delta on Mars.

A multinational team of scientists have for the first time observed an almost 1,000 km-wide swirling vortex of plasma that rained electrons down on the Earth from the stratosphere. The team, which included researchers from China, Norway, the UK and the US, were searching through archives of satellite images from years ago when they caught the phenomenon, which had been recorded right over the North Pole. According to NBC News, the phenomenon has been dubbed a “space hurricane” due to the behavior of the plasma. Larry Lyons of UCLA iterated: “You could see flows of plasma going around, which were like the winds of the space hurricane. These flows were strongest at the edge and decreased as you moved toward the eye in the center, before picking up again on the other side, just like the flow of air in a regular hurricane.” “It really wasn’t expected. It wasn’t even theoretically known.”

Third time was almost the charm. SpaceX’s latest prototype rocket landed in one piece on Wednesday — following two recent test flights that ended in huge explosions. But minutes after cinching the touchdown, the test rocket blew up into a giant fireball. The Starship Serial Number 10, or (SN10), blasted off from Boca Chica, Texas, at around 6:15 p.m., after an earlier flight attempt was aborted earlier in the afternoon. The steel rocket flew as high as 10 kilometers, or about 32,800 feet altitude, before turning to a horizontal “belly flop” position and executing a series of complex mid-air moves. It then came down upright, making a soft landing at around 6:21 p.m.

Can physics prove if God exists?

I still believed in God (I am now an atheist) when I heard the following question at a seminar, first posed by Einstein, and was stunned by its elegance and depth: “If there is a God who created the entire universe and ALL of its laws of physics, does God follow God’s own laws? Or can God supersede his own laws, such as travelling faster than the speed of light and thus being able to be in two different places at the same time?” Could the answer help us prove whether or not God exists or is this where scientific empiricism and religious faith intersect, with NO true answer? David Frost, 67, Los Angeles. I was in lockdown when I received this question and was instantly intrigued. It’s no wonder about the timing – tragic events, such as pandemics, often cause us to question the existence of God: if there is a merciful God, why is a catastrophe like this happening? The idea that God might be “bound” by the laws of physics – which also govern chemistry and biology and thus the limits of medical science – was an interesting one to explore.
