Norway — There is a solution for the world’s insatiable energy needs. It is CO2-free and safe. And it’s located right under our feet.

Ever since Jules Verne wrote in 1864 about a trip to the Earth’s interior, people have dreamed of bringing up heat from the centre of the planet. So far we have only scratched the surface, but researchers are now beginning to work down into the depths.

In celebration of the 31st anniversary of the launching of NASA’s Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant “celebrity star,” one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust. Credit: NASA, ESA, STScI

The mighty blue giant AG Carinae is not your normal star. One of the brightest stars in our Milky Way galaxy, AG Carinae is sizzling hot, shining with the brilliance of 1 million suns. You would need super sunscreen if you lived in the star’s vicinity. The star is up to 70 times heftier than our Sun and burning fuel at a ferocious rate.

While leaded gasoline was fully phased out in 1996 with the passage of the Clean Air Act, it still fuels a fleet of 170000 piston-engine airplanes and helicopters. Leaded aviation fuel, or avgas, now makes up “the largest remaining aggregate source of lead emissions to air in the U.S.,” according to the Environmental Protection Agency.

Meanwhile residents continue to live with the air quality that comes with living near an airport where small planes burning leaded fuel fly in and out, said Alarcon, who is also a volunteer organizer with the nonprofit tenant advocacy group Vecinos Activos. It’s also unclear to air quality experts and residents what is arguably safe.

“There is no bright line that says ‘Above this concentration lead is safe and below this concentration’ that it is not. You’d have to make a policy decision,” said Jay Turner, an engineering education professor at Washington University in St. Louis and member of the EPA’s Science Advisory Board. “We’re really careful to come back to this point that just because public areas might meet the EPA standard [for lead] doesn’t mean zero risk or zero concern.”

They require less maintenance, and less pollution. Imagine if you used them as a battery backup during an emergency.

School board seals deal to bring 300 electric school buses to Montgomery County. The buses will recharge at night and run during the day. During the hot summers, the buses and charging stations can help store needed energy for local businesses.

Pyongyang’s recent ballistic missiles test indicated that the country is once again raising tensions to gain leverage with Washington.

A tidal turbine weighing 680 metric tons and dubbed “the world’s most powerful” has been launched from the Port of Dundee in Scotland, marking another significant step forward in the development of the U.K.’s marine energy sector.

In an announcement Thursday, Scottish firm Orbital Marine Power said its 2 megawatt (MW) turbine, the Orbital O₂, would now be towed to the Orkney Islands, an archipelago north of mainland Scotland, for commissioning.

The plan is for the turbine to then be connected to the Orkney-based European Marine Energy Centre, where it will become operational.

The NASA Perseverance Rover has a device aboard called MOXIE that will convert the air available on Mars into oxygen. The device is a test, and if the technology was used on a larger scale could produce oxygen for humans to breathe on the Red Planet and could be used for rocket fuel. NASA knows that one of the most challenging parts of putting people on Mars will be getting them off the planet and back to Earth.

A team of researchers at Technion—Israel Institute of Technology has developed a new technique for conducting real-time evanescent wave imaging using standard optical technology. In their paper published in the journal Nature Photonics, the group describes their new technology and ways they believe it can be used in photonic device characterization and other applications.

Evanescent waves are oscillating electric or magnetic fields that do not propagate—their energy remains in the vicinity of the source that created them due to a quickly decaying amplitude. They play an important role in acoustic and optical applications. Guided waves, on the other hand, have certain frequencies and energy that can travel very quickly along a designated path—they also leave a trace of their passing—an evanescent wave that decays so quickly that it is very difficult to see it with standard technology. Past attempts to image them have run into trouble, such as perturbation in the field under study, long acquisition times or the need for complex and expensive equipment. In this new effort, the researchers have developed a technique for measuring and imaging evanescent waves that overcomes all these problems.

The work involved studying evanescent waves of light by mixing them with a laser beam. Doing so resulted in the creation of a new frequency that could be both seen and studied. The method works, they note, because the laser changes the direction of the electric field. They found during experimentation that they could create different shapes using the laser. And further study showed that it was possible to both insert information into the evanescent waves and to take it out when desired. They also found that the shapes could be imaged using standard commercial cameras. The team calls the new technique nonlinear near-field optical microscopy and note that it does not require exotic equipment and can be done at very little cost.
